Dear Sir. My Idea is on Increasing the agriculture production. In today's world land is decreasing day by day for living and cultivation.we are moving upward in tall buildings to utilize air space for living. At the same we can use this concept in agriculture also.I call this Mirror agriculture Technique. we can do vegetation on all the floors of building.and the sunlight can be provided with mirror reflection or some type of fiber optics . Waiting for your reply. Nikhil Gupta

The thoughts of engineering can be outdated before building even begins. the simple task of research and development could go on infinitly in theory on paper but it is the physicsl test that unvovers flaws in the design, materials, unforseen elements and physical limitations and components. With the information we have today this too can now be done on paper and tests can be carried out in a theoretical windtunnel based on the data collected from previous tests so the whole process of building certain mecahics no longer is required because it either already exists and the data collected could be used. This would free up nations from unnecessary labor, expenses and resources/funding if there was a global pool of...oh wait the internet... the problem now lies in choices, trends and social phases, and financial traffic if money was considered vehicles on roads and shops or expenses the destination. What is attracting the traffic, where is if blocked, flowing, lost? The world needs to find a base focus that it can work towards in any given location and once again I go back to the basic elements and food and water. any given human would appreciate a meal and a refreshment depending on the trade but in some cases it is already owed...

Thinking first. Switch 99.9% of people from repeating the same old things to the majority thinking. Move a 1000 years in day. Break the link between a calendar and events in them. A year can carry unlimited thoughts. Unlimited developments. Humanity hasn't moved since our evolution. In the same galaxy, same solar system, same planet, same land masses, live in the same square boxes, travel up the same flat crowded roads, make up the same gods, fight the same wars, collect the same plants, eat the same food, have the same sex and die the same death. Nothing changes. We dont even live in two thirds of the planet or five feet either side of the biosphere. We're self satisfied two diemensional flatlands monkees with the added burden of organised superstitions. Electronics has not even increased its rate of improvement for forty years. No improvement in Moore's law, ever. Hopeless. Why hasn't the rate of improvement doubled every eighteen months, now that would have delivered a billion times the computing power by now. 35 hour weeks and research grants are the reason. Weeks have 168hrs. The prime directive is to think more time. To eliminate death Time second. We use this added life time to think. Think how to connect intellect. To instantly communicate. Energy third and Resources forth. The output of thought after time, is then energy. Fusion energy. Nothing else is worth a candle. Forget all the silly voodoo green sources, they are many orders of magnitude too tiny. We need energy to travel stellar distances and to mine and convert vast resources. I tire of small thinking, This planet has 40000 tons of extra resources each year. Nothing over a few tons ever leaves. Everything that ever was here, is here. All we need is energy to convert it. With energy and what we have, we can make everyting we need a billion times over, for ever. And then we can accept our real responsibility and search the universe. We need to stop burning down human libraries and stop death, now. The strange thing is, I sound like the mad person. Not the rest of the planet. Never laugh at the past, its still a flat earth. Nothing changes.

Saves money, and its simple, only until you find a way to make a netting solution that would be harmless to the o-zone, or anything else up there, or even that small to even capture Co2. It also would help our o-zone with all the Co2 being burned and released. Save us a couple more years, save the earth a couple more years.

I've got an incredible idea for flying cars that are VTOL and electric. What makes my system superior is the efficiency factor, which is at 90%, a vast improvement over traditonal aircraft. All airplane wings and helicopter propellers produce drag to generate lift or thrust, but they waste the majority of energy put into the drag production, whereas my system uses almost all the drag produced for thrust and/or lift. This is a revolutionary idea that is based around simple drag physics that have been proven for centuries, meaning there is no chance of failure. Practical VTOL flying cars can be produced in our lifetime with this technology and this is not too good to be true, it is only physics being applied in an outside-the-box sort of way.

I disclosed how get existing or new non-accelerated vehicles and other machine that save much energy and directly or indirectly emit least emissions in the world: Creator’s idea is non-accelerated, quiet, and green vehicles and other machines are disclosed by two USA patents 8,011,274 at 09/06/2011 and 7,191,676 at 03/20/07 for making money by both manufacture and customer; prevents environment and economic collapses. There above 1,000 state-of-the-arts gearbox apparatuses designs are created by revolutionary methods. What are the main 7 differences in design (other at www.repowermachine.com)? 1. It has least numbers of gears/maybe shafts in the world without competitors in future; 2. It is not brake in the propulsion of machine, uses only one torque or speed of motor shaft and produces all needed speeds including the sufficient number of overdrive speeds that eliminates motor interior gas or magnet field acceleration system and its noise; 3. More simple shifting mechanism design opens opportunity to create three regimes as manual, semi-automatic and automatic simultaneously with operation by computer; 4. It reduces energy consumption, emissions, noise, power and cost of motor in many times; 5. It improves driver’s safety by simplification of operation; 6. It improves maneuverability: a) driver saves time in the movement by getting each speed with zero time of vehicle acceleration and many higher reverse speeds without additional gears; b) it expands the range of speeds up to 272 forward/170 reverse overdrive speeds/torques by adding only 2 shafts to existing heavy-duty truck gearbox of 18 / 2 torques; c) driver uses front on uphill and rear on downhill, or all wheels temporarily for additional saving energy; d) aircraft or watercraft have much increased turning speed if uses it instead existing operation system. 7. Its production uses the same machine tools and other items of existing manufacture. Why is much reduced motor torque or power magnitude? Well-known maximum torque of vehicle wheels is calculated so: friction coefficient (0.7) between wheels and road on stop by weight with biggest load by radius of wheel. Then it by ratio of differential gear and pinion is torque of gearbox output shaft. Highest torque of its input shaft is torque or power magnitude or size of motor. There are examples: 1) Existing transformed non-accelerated heavy-duty truck Volvo VGD has 20 forward/5 reverse torques/overdrive speeds gearbox apparatus comprising 20 gears/3shafts or 40% number of gears and four shafts less than its shift gearbox of 18/2 torques. It reduces motor power in 4 times (500 hp to 123 hp). Driver of the long haul tracking saves above $25,000 per year by diesel ($3) economy in 2 times and saves by increased speed on uphill if it is fully loaded; 2) Existing transformed non-accelerated Toyota Camry could have gearbox apparatus of 12 forward only overdrive speeds/ 4 reverse by 16 gears/ 3 shafts or one gear plus to existing gearbox of 6/1 speeds. It reduces motor power in 9 times (178 hp to 20hp); 3) Existing transformed, non-accelerated CNC Knee Mill spindle joined to automatic programmed gearbox apparatus of 64 torques and overdrive speeds by 7 shafts/32 gears. It joined to Dayton motor of 1/2 hp that replaces expensive programmed motor of 5 hp and could reduce power in 10 times that provide reduced cost in 2 times ($35,560 to $18,000) less. 4) Much lower interior temperature of motor eliminates condition of the harmful gas - nitrate oxides (NOx) creation that is main killer of life on Earth. According to Peter F. Ducker “Business has only two basic functions-Marketing and Innovation”. Expensive machine market is much more dependent to number of customer high-paying jobs and customer’s interest to save health and money than the markets of other products. The crises USA automakers have disclosed the wrong way of machine creations are based on permanent aid by taxpayer’s dollars where “In God we trust” wrote and incorrect information. Human wisdom of past ignores Creator’s Physics Laws of Lever and Inertia in the machine designs are based customer’s interest to save money and health by using more clear air. They created innovations for getting “easy” money by: a) using gas or magnet field for many thousands pounds acceleration; b) using radius of motor shaft as level by directly jointing to wheels or propeller or spindle; c) using each transmission as second brake to the acceleration system that wastes up to 80% mechanical energy in form of motor heat; d) using two clutches with name “automatic transmission of torque convertor and continuous variable transmission” that never get timely higher torque/lower speed before reaction of motor with excessive power. Those are not available any longer. Today the prices of energies, numbers of machines, technical progress, education, global communication, environment disasters and people premature deaths from lung diseases are increased in many times that require to stop ignoring the steel lever in each machine design. Maybe shift gearbox has limited little gear ratio as planetary transmission design or has competitors between existing other transmissions? No, there are incorrect. The pair of gears uses only 2% energy that is least magnitude in the world and it could reduce motor torque in up to 7 times. For example, shift gearbox of seven shafts could reduce the torque of motor in up to 7x7x7x7x7x7=117,649 times but it wastes only 2%x6=12% energy. Please contact me if you are interested in licensing the patents and desire a relationship with me to develop gearbox apparatus systems for existing vehicles, CNC machine tools, heavy-duty equipment etc

The train system should be improved for the future generation with magnetized modern trains with top speed of 300km/h. The future MEGASTRUCTURES shoul'd be starting to be built becasue the population is massive and a safer way is to build in the sky. Like the Mega Sky Citties that are starting to be built it's like a massive tower with a city inside with elevators,apartments,ice-skating centres,shopping malls,homes,pools,hotels,offices,studios,sport centres and so much more. If this is achieved it will be a clue for the future generation and afcorse the rest of the world. The Tower's can also be joined by sky tunels and sky bridges, so if there's soemthing in the other tower that's not in this tower the people can cross to the other tower. In 2015 those megastructures will start to be built. And by 2050 there will be alot of robots that will replace humans on the construction sites,all humans will have to do is control the robots by computers and other futuristic technology.

Does anybody know how these challenges were chosen? What was the criteria? Are they chosen to save lives? To improve society in some unified way? Ideology driven? Clean water would go a long way to saving lives. Better tools (my choice for #1 on the list) enable solving all of the other problems plus cross over to many other problems. Reading the documents about the selection, the theme I get is "This century our unsustainable society will start to collapse without these improvements". Thoughts?

"" 

The Grand Challenges proposed by the National Academy of Engineering are fantastic! Six of the fourteen, arguably, are directed at achievement of a sustainable human society. The concept of a sustainable society is, however, not mentioned on the academy's main web page. Also, a more holistic approach to supporting programs that identify the needs of a sustainable society and the tools to get there should be provided in my view. Don't we want human society to be sustainable? We must act soon if that is to happen in a planned and organized fashion. How do we do that? What technologies are needed? What current technologies should be replaced with something better? What is the infrastructure of a sustainable society? Does our current infrastructure just need updating or, rather, a fundamental restructuring and replacement? The Grand Challenges should address those questions.

I am a high school graduate, but I haven't gone to college yet. However, I have the thought experiment that allows me to figure out ideas, including a wide range of details, big and small, without a physical demonstration, or taking a class for it in my life. So I have a lot of certainty, although no experience from school or college. I have skill in checking in all the choices I have, big or small, and putting them together and finding a solution. With all this, I have ideas for how the transatlantic tunnel could be much more reachable in modern science, technology, and more affordable, or profitable. How the tunneling by itself could be completed within a decade, no water/weather/temperature challenges, less dependantcy on steel mills, and less shipping. Also how the cost could be dropped by 5 times, possibly more. Also ways to charge passengers that could mean a faster rate of recovery of the cost of everything payed to build the structure. Also ways to reduce g-force effects and without cutting down passenger capasity and without additional power cost. The total cost might be dropped down by 90%. But the beginning of profit earnings might still be a long time away, but the reducing of 90% would be a good head start, considering the economy. And on their way, time will tell if the cost dropping of 90% will increase to 91% or more. There will always be time for another drop. Never too late, even though the sooner the better. Even if the economy improves. Money/profit is the goal. Never lose hope for a better future. That's how I think about it. But would they believe solving these challenges I mentioned, especially the cost, should make the Transatlantic Tunnel reachable enough that it would be no more hazardous as the Bering Strait Tunnel, considering the cost and dangers of building thousands of miles of railroad from both ends added together?

Hi, I reached here via InnoCentive. Why we only think about an economic solar electricity. We can think other way to use the solar energy efficiently. I'm not an engineer or reasercher. I have a doubt that why we are not combining the technology of Absorption refrigeration system and Solar energy. According to my knowledge, Absorbtion refrigeration system only researched or used by Japan or Korea. Why other contries (Companies) not using this technology. If we combine, Solar and absorption refrigeration system for Airconditioning at least in Day time, we can use solar heated water for heating the generator of absorption refrigeration plant and Solar electricity for pumps. That means entirely grid power free airconditioning for sunny and hot areas like Northern India. I think no need of drastic changes required for this. Already absorption plants using hot water, hot air or steam for heating the generator of the absorption refrigearation plant.

Thinking outside the box, new approach to “flushing”: What better way would it be if we “flushed“ our toilet with Air instead of using water and wasting water (which is mostly drinking water) to transport our “message” from A to B. From A, the toilet to the B, the wastewater treatment plant. By flushing with Air we save an enormous amount of water only less than 1 litre is used to flush instead of 15 litres. Imagine a boarding school with 500 students. Water to flush the toilet is normally 7500 litres per day, this is 1.875.000 litres per year. With Air this is only 125.000 ltr per year. 93% savings This way we would not need any expensive waste water treatment facilities that only consume energy. If We collect all this organic (faecal) matter ("blackwater with a minimum of water) and digest it in an Anaerobic digester with all organic kitchen waste, from preparing the food and the returns / leftovers, we can produce methane gas for heating /lighting or cooking In the Anaerobic Digester all organic material is digested by Anaerobic Bacteria and Biogas is formed (Methane and Carbon di Oxide). This Biogas can be used to burn and cook the meals or in a heating system. The amount of Biogas generated is approx. 20 litre per day per person. A boarding school or hotel with say 500 people/beds would produce ca. 10.000 l Biogas/day. ENVIERHO AQUA PROTECT ‘s intention is to market and sell vacuum systems linked to an Anaerobic Digester that will produce methane gas for heating and cooking. This concept could be easily implemented where we have a concentration of people. - Large boarding schools with canteens. - Larger cluster of apartments. - Prisons. - Large hotels with restaurant - Hospitals with kitchen. - Cruise ships. - Larger camping sites. - Holiday homes clusters. - Army Camps - Refugee camps To get this concept implemented a Pilot Scheme is required to proof its viability.

Hi, I followed the path from Innocentive. I was interested in healthcare and I have been working on something myself. There are certain areas where I lack experience and doing this alone will likely take a long time. Let me tell you one of my visions. I got physically sick around 3 years ago. My dad had a heart attack. My mom was already having health problems. I want to help the world learn how to eat again with the various health conditions. I believe it is possible to write a computer program with all of the nutritional data we have on food and disease. This program that I am thinking about would hopefully be able to give a patient the knowledge they would need to eat healthy with whatever ailment they are experiencing. It would also allow people to make the food banks of better utility for those in need. When I had to use a food bank I ended up giving some of it away because of my sensitivities. If we could find a way to feed the most people without the likelyhood of causing a reaction or health concern, we could utilize the information to help the food banks as well as oversea hunger problems. I suppose I am dreaming of software that would take a lot of data entry. I do not know where to find lists of premade data tables that I may be able to use. I also do not know how to write the program in computer language. But, I do know it will likely take me much longer to do this on my own. I have many ideas but I am not sure where to give them away or where I can find help in implementing them. I am also unsure of where you could go to submit for challenges.

For provide access clean water it is nessacary Water Treatment Plants correct design. A main unit of that Plants is Settling Tanks or Sedimentation Basins because there are detained about 95-96% of suspeded solids. But Settling Tanks design has a great problem at the present time. The reason of this is next: more than 100 years ago was developed traditional(conventional) theory for Settling Tanks design on the basis of the Newton gravitational law and Stokes equation. But thanks to this theory it is impossible to calculate the sizes of Settling Tanks and to create models of them and to choose effective one. It is unbelieveable, but for Settling Tanks depth calculation all manuals and books are recommending "ideal sedimentation basin" where settled spherical particle . That theory is very effective for chemists, biologists, but not for engineers. For decision above broblem 1991 the I developed Alternative Sedimentation Theory on the basis of the Newtons Second law: http://knol.google.com/k/sadyrbek-djighitekov/alternative-sedimentation-theory/1cs9gt8jgdjvm/9# Example for Rectangular Tanks design is given on the web: http://knol.google.com/k/sadyrbek-djighitekov/settling-tanks-basins-design-on-the/1cs9gt8jgdjvm/2# Everybody can visit to discussion forum too: http://www.waterandwastewater.com/cgi-bin/yabb/YaBB.pl?num=1232599276/41 - On the basis of the Alternative Sedimentation Theory it is possible Settling Tanks Design accurately; - Thanks to above theory it is possible to create models of Settling Tanks types and to choose of effective one; - Alternative Sedimentation Theory is very effective for students of the universities for clear understanding of Settling Tanks Design; - That theory give a great opportunities for management of water and waste water treatment plant for economy chemical coagulants or improve sedimentation process in Settling Tanks. The conventional(traditional)sedimentation theory can not give above opportunities for scientists, experts, engineers, and students. Support of the new approach for Settling Tanks design by National Academy of Engineering would be great support Challenge in the field of World Water Industry.

I am promoting inventions in the field of engine-building. At present there are issue international patents for two inventions. The core of know-how is a completely new conception of structure of internal combustion engine. This is not a technology, but this is a new and fairly simple principle of structure of an engine without using a crank mechanism. The inventions are at the "Idea and research" stage, but for technological implementation there are required a lot of funds. Concerning know-how advantages: The project can be considered as a social one as it has a direct relation to reduction of CO2 emission to the air. The principle allows to construct an internal combustion engine in such a way that combustion mixture can burn down almost up to 100%, thereby it helps to minimize CO2 emission. These decisions are in no case reflected on engine power, even vice-versa increase indicated power two, three, four times as much reducing fuel consumption at the expense of structure downsizing.

Consumerism is the root cause of most of our climate and social issues. There are the few who can afford everything in excess and the many who can not afford even the basics.

All great technological innovations need to have a social understructure to function. It would be great to have new sources of energy, but we all know it comes with a price that someone sets to profit themselves.

Sincerely Byeungok Oh (lccobok@yahoo.co.kr) L.C.C. life environment research institute 10-9 haewhadong jongrogu Seoul 110-530 South Korea Attched: Medicine improvement by the artificial mitochondria that come true newly It does not realize between continuous time passes and energy balance equilibrium state is kept constantly. To hang in physiological function of cell overly and Purpose function of cell being not grasped, it is foreseen that fair flustered feel will go first that artificial mitochondria device is pronounced. Substance of energy is managed by some route anything really? But Question can go first. As present drug stuffs form, even if energy utilization state is microbial outgrowth unit or is used in human body by herb medicine ingredient unit customary. This very small quantity being used and Change is various kinds thousand that is accompanied here. Specially, human body sees as is reacting in always fixed form, but it is not equal feedback. As form one�@ circulation, because keep feedback. Although it is difficult that present model of some form, Unit model circumstance disposal is much easier if is mixed as complex and it must to be always fixed do according to last presence at a clinical result and keep this level. System function weighs so far and although spoke that reaction for this function is important, because all situations are variable, it was not agreed easily. Energy generation that is human body main reaction, nutritive substance transport, exchange, reaction path connected with excretion create and disappeared thing is situation occasion although it is suspended if do even if full . These situation cell or the formation agency of as function originally, All components are wormed orderly. But, it must atomize here much more and examine. It must divide condition and human body formation physiological function that human body formation component is arranged with optimum function preservation. Otherwise, fall at discord if it does not adjust balance even if it is emphasized one�@ side. It arrives in one�@self own collapse. Alternate the formation agency of corresponded part when is such. Although it is preferring excessive method to rescue function, is not problem solution. Because controversial point of inside is indwelled. . Also, it is going to have a hasty decision to remove own collapse part, but it is temporary expedient as well as this. As see while it does, it can not equal super computer how much compensated organization and institutions are how bulky. By the way, it is great development that chases gene change recently and arrives in disease treatment. Although minuteness diagnosis and assay can be available to micro tissue overly among these trends, it is very inefficient. Also, in such a case it is thing similar to very inappropriate disposal situation in acute situation of system control command department. If one�@ is spot responsible person, how does it may control? It must connect being detoured if nerve control is problem. Organization need to do construction in beam style support thing by urgency processing if it was damaged. After it handles surgical situation of these method, Energy supply of drug delivery way follows. This method is being not becoming minuteness control entirely. Still, it guides to organization which become an issue like missile and Do even if do so that effect may appear time lag like time capsule shape, it is going to minimize drug stuffs side effect, but is the station tribe. Still, improved a little, the effect preservation is limited extremely and can not escape limit situation. Also, change by special skill that is contributed by one�@ expedient and is getting stabilization easily. However, mechanical heart industry falls in stagnation representatively, is staying in presence at a clinical level continuously. It is a little inconvenient in recent science level. All sides of human body are stagnated and are degenerated but It must define state that is gotten back in various disease syndromes clearly newly. It is not gotten back that get travail effect by some drug stuffs taking medicine. It is not gotten back that cut formation which function is suspended and is collapsed by radiation and remove by surgical operation. So, although party satellite of rehabilitation medicine will be formed, We must supervise responsibility why we aggravated situation in this way. Gene defect is indwelled because disease symptom is not come to the fore, time passes Or, economical reason can be. At the some moment, patients who appeal bodily languor can lift that is many. It is most workpeople, but because connected production efficiency drops rapidly. Even if severe labor condition is improved by much production facilities automations, It been going side by side business stress can not avoid and hygienic condition is worsened remarkably. As it is going to minimize life risk to various kinds economy leading composite index, weather forecast information etc. present, it must hydrate health information since and do life. If discomfort index is high, human body atomizes health index as operate air conditioner It should be forecasted commonly and should be managed. So, important health power of a number will be judged that is managed by a constant time medical examination, but it is big mistake. And method that can get health improvement from a medical examination is ephemeral as method or kinesiology experience and is not forming system. This state can announce health safety low limit critical state. This moment is overlooked mostly and is not managed. So, by suitable model system operation administration although took example. is similar to be difficult to do to recognize situation. But, if onc�@e more example to be delayed constantly if exchange battery, watches the effect prove. Similarly, level should be kept as summit human body is that human body use artificial mitochondria device. Therefore, what is free energy from metabolize energy level change and essence being, what is achieved career. Important bolt is going whether is regulated in some route and is gotten back. So, it is thing which gives a name as artificial mitochondria device and proposes and does. But, medical world expects thing supplied freely cultivating trunk embryo bud cell. If speak as artificial, although it can do that is not clinical two like mechanical heart and do inquiry, To embryo bud stem cell keeps stationary state, minuteness environment should be supported. It can not overlook level is free energy that is happened in metabolize energy, can not be formed altogether. Also, human body as system is ATP energy supply and demand situation forecast can, It does not examine closely ATP energy essence continually and is grasped that is energy that is happened in conversion between ATP and ADP. Nothing is marched in this state. There may be composure yet When blow upon critical, situation can not estimate roughly by special quality half-life if pass a little. Have you to abandon still? By automation already in system control command room system safety run, In human body system any confrontation do not ready also action step ready. If see the main mitochondria function, If oxygen per alveolus, enzyme etc. that is carried in blood is supplied and is assimilated to mitochondria like sponge, expected compression heat occurrence effects are accompanied. So, energy is stored to ATP, energy supply and demand circumstance becomes very unstable as for this path. And it can say as formation agencies�f physiological function that reaction action is gone by ATP system energy supply. Energy source should be supplied and is overlooking by bigger efficiency than this. So, when explain applying by system model, agreement does not become. Therefore, energy save medium and career are defined newly and are normalized. it can help function in human body that do artificial mitochondria energy development device. Is ideological and abstract yet? Because adjustment is available onl�@y energy career Indiscretion energy avoids side effect being supplied like covenant. First of all, it is energy save medium. It speak that energy was stored in fattiness quantity, but direction energy supply medium is not examined closely yet. Such series process can assume easily to system administrators and is grasped. Although reposed wall one�@ is human body cell and another is never easy to fusion each other as is the inorganic matter molecule world According as career of energy supply process and common homogeneity of medium are embodied, the importance of fusion�fs learning is emphasized. Although it is applied by various kinds field, Because focus and examine again, is participated together and when standardization is gone ahead Human health contribution becomes advance.

I think engineering can, for one, help the economy. Well, right now there only a few things that could accually HURT it, if you know what I mean. But also I beleive that it helps in four other areas: Entertainment, Experience, Saftey, and Productivity. I just saw this thing about this engineering company in Germany that created a mechanical flying penguin. They said it could be used to deliver mail, wich would be okay but more to humor them then anything, but if they began selling those on the market, that could really encourage the younger generations to go outside and run after them, because, what's a TV compared to a flying penguin? Engineering could work in the opposite way, too, though. Also, experience. There would be so much different variety in life if you technology that alowed you to do things you've never done befor. Thirdly, Saftey. What if car crashes became so strange that they happened once a year? I'm reffering to pre-existing tecnology that people use on a daily basis to be improved. I'm not saying that it would be good if they invented aa chip that goes into your head that stops a murderer from killing someone. And finally, productivity. Faster things being made, stronger things being made, stronger alloys being formed, deeper caves being dived into, faster ships bringing human life to study mars, more accurate weapons to nuetralize terrorists and not their hostages. There really aren't many ways for advances in technology to NOT help society. And, no, I really don't think that technology will be taking over. That's really just sci-fi movies and Ray Bradbury novles.

Engineers and Scientists exist in harmony with one another because they are have been able to create a mutualistic relationship. Engineers design the tools Scientists need to explore the world. Scientists develop the knowledge and principles Engineers must follow when creating the world around us. Therefore, if Engineers discontinue creating tools, Scientists discontinue the ability to discover the world around us. Life in the Informative Age is based upon the ongoing ability to constantly discover. There are still questions out there in fields such as biology, astronomy, chemistry, and general exploration. With new tools comes new knowledge. With new knowledge comes evolution of the standard of life.

I think gladly that do in NAE my proposal for information interchange and community. As new paradigm of modern medicine, I propose perfect solution that treats disease. I presented my proposal in NAE for a long time but was not examined. Because power of expression is insufficient and research environment is unprepared and was going to avoid that study so alone, but hard problem appears go. First of all, we should be contributed in mankind health because establishing medical treatment standardization with me. Thank you very much. Sincerely Byeungok Oh (lccobok@yahoo.co.kr) L.C.C. life environment research institute 10-9 haewhadong jongrogu Seoul 110-530 South Korea Attched: Medicine improvement by the artificial mitochondria that come true newly It does not realize between continuous time passes and energy balance equilibrium state is kept constantly. To hang in physiological function of cell overly and Purpose function of cell being not grasped, it is foreseen that fair flustered feel will go first that artificial mitochondria device is pronounced. Substance of energy is managed by some route anything really? But Question can go first. As present drug stuffs form, even if energy utilization state is microbial outgrowth unit or is used in human body by herb medicine ingredient unit customary. This very small quantity being used and Change is various kinds thousand that is accompanied here. Specially, human body sees as is reacting in always fixed form, but it is not equal feedback. As form one�@ circulation, because keep feedback. Although it is difficult that present model of some form, Unit model circumstance disposal is much easier if is mixed as complex and it must to be always fixed do according to last presence at a clinical result and keep this level. System function weighs so far and although spoke that reaction for this function is important, because all situations are variable, it was not agreed easily. Energy generation that is human body main reaction, nutritive substance transport, exchange, reaction path connected with excretion create and disappeared thing is situation occasion although it is suspended if do even if full . These situation cell or the formation agency of as function originally, All components are wormed orderly. But, it must atomize here much more and examine. It must divide condition and human body formation physiological function that human body formation component is arranged with optimum function preservation. Otherwise, fall at discord if it does not adjust balance even if it is emphasized one�@ side. It arrives in one�@self own collapse. Alternate the formation agency of corresponded part when is such. Although it is preferring excessive method to rescue function, is not problem solution. Because controversial point of inside is indwelled. . Also, it is going to have a hasty decision to remove own collapse part, but it is temporary expedient as well as this. As see while it does, it can not equal super computer how much compensated organization and institutions are how bulky. By the way, it is great development that chases gene change recently and arrives in disease treatment. Although minuteness diagnosis and assay can be available to micro tissue overly among these trends, it is very inefficient. Also, in such a case it is thing similar to very inappropriate disposal situation in acute situation of system control command department. If one�@ is spot responsible person, how does it may control? It must connect being detoured if nerve control is problem. Organization need to do construction in beam style support thing by urgency processing if it was damaged. After it handles surgical situation of these method, Energy supply of drug delivery way follows. This method is being not becoming minuteness control entirely. Still, it guides to organization which become an issue like missile and Do even if do so that effect may appear time lag like time capsule shape, it is going to minimize drug stuffs side effect, but is the station tribe. Still, improved a little, the effect preservation is limited extremely and can not escape limit situation. Also, change by special skill that is contributed by one�@ expedient and is getting stabilization easily. However, mechanical heart industry falls in stagnation representatively, is staying in presence at a clinical level continuously. It is a little inconvenient in recent science level. All sides of human body are stagnated and are degenerated but It must define state that is gotten back in various disease syndromes clearly newly. It is not gotten back that get travail effect by some drug stuffs taking medicine. It is not gotten back that cut formation which function is suspended and is collapsed by radiation and remove by surgical operation. So, although party satellite of rehabilitation medicine will be formed, We must supervise responsibility why we aggravated situation in this way. Gene defect is indwelled because disease symptom is not come to the fore, time passes Or, economical reason can be. At the some moment, patients who appeal bodily languor can lift that is many. It is most workpeople, but because connected production efficiency drops rapidly. Even if severe labor condition is improved by much production facilities automations, It been going side by side business stress can not avoid and hygienic condition is worsened remarkably. As it is going to minimize life risk to various kinds economy leading composite index, weather forecast information etc. present, it must hydrate health information since and do life. If discomfort index is high, human body atomizes health index as operate air conditioner It should be forecasted commonly and should be managed. So, important health power of a number will be judged that is managed by a constant time medical examination, but it is big mistake. And method that can get health improvement from a medical examination is ephemeral as method or kinesiology experience and is not forming system. This state can announce health safety low limit critical state. This moment is overlooked mostly and is not managed. So, by suitable model system operation administration although took example. is similar to be difficult to do to recognize situation. But, if onc�@e more example to be delayed constantly if exchange battery, watches the effect prove. Similarly, level should be kept as summit human body is that human body use artificial mitochondria device. Therefore, what is free energy from metabolize energy level change and essence being, what is achieved career. Important bolt is going whether is regulated in some route and is gotten back. So, it is thing which gives a name as artificial mitochondria device and proposes and does. But, medical world expects thing supplied freely cultivating trunk embryo bud cell. If speak as artificial, although it can do that is not clinical two like mechanical heart and do inquiry, To embryo bud stem cell keeps stationary state, minuteness environment should be supported. It can not overlook level is free energy that is happened in metabolize energy, can not be formed altogether. Also, human body as system is ATP energy supply and demand situation forecast can, It does not examine closely ATP energy essence continually and is grasped that is energy that is happened in conversion between ATP and ADP. Nothing is marched in this state. There may be composure yet When blow upon critical, situation can not estimate roughly by special quality half-life if pass a little. Have you to abandon still? By automation already in system control command room system safety run, In human body system any confrontation do not ready also action step ready. If see the main mitochondria function, If oxygen per alveolus, enzyme etc. that is carried in blood is supplied and is assimilated to mitochondria like sponge, expected compression heat occurrence effects are accompanied. So, energy is stored to ATP, energy supply and demand circumstance becomes very unstable as for this path. And it can say as formation agencies�f physiological function that reaction action is gone by ATP system energy supply. Energy source should be supplied and is overlooking by bigger efficiency than this. So, when explain applying by system model, agreement does not become. Therefore, energy save medium and career are defined newly and are normalized. it can help function in human body that do artificial mitochondria energy development device. Is ideological and abstract yet? Because adjustment is available onl�@y energy career Indiscretion energy avoids side effect being supplied like covenant. First of all, it is energy save medium. It speak that energy was stored in fattiness quantity, but direction energy supply medium is not examined closely yet. Such series process can assume easily to system administrators and is grasped. Although reposed wall one�@ is human body cell and another is never easy to fusion each other as is the inorganic matter molecule world According as career of energy supply process and common homogeneity of medium are embodied, the importance of fusion�fs learning is emphasized. Although it is applied by various kinds field, Because focus and examine again, is participated together and when standardization is gone ahead Human health contribution becomes advance.

Everyone keeps saying " Wouldn't it be nice if only . . .but not many people actually work at the problems on their own account. Yet, there is an American and Western-Civilisation tradition for individuals to tinker with hand, brain an own resources to meet problems head-on by solving them, first in a small way, then all the way. I can quote names like Joule, Watt, Edison, and Ford, which leaves out multitudes of those who made it and of course, those who gave up before they made it I have a serious "work-in-progress" proposal for a "solar energy combine harvester", some definite details of which are already disclosed on my blog with "engineering.com". To anyone who back-tracks these disclosed details and wants to know more, I will answer with facts, figures, text and pictures from my open "Project Portfolio". My target, to be actually demonstrated at artisan scale with models I personally build, is : concentrated heat resulting from 70-times concentration of rays, at a cost of 10 US cents per kilowatt hour. The heat is then to be converted into electricity by a reciprocator directly powered on the sun-follower rig, via pneumatic or compressed air that drives the rotary electric generator. Evidently, a working- fluid is heated in a very innovative concentration target, - water-steam or hot-pressure air both suitable. A payback of investment within one year is plausible, but has to be proved. Completion target for my end of the project - midsummer 2011.

I completely agree with Peter from Arizona. Living in a country when the Sun beats down throughout the year, I am appalled at the minuscule number of solar panels I have seen. I know that they are hardly efficient due to the lack of intensity per square area, and that they very costly, but, as Peter said, this is one resource, i hope, the world will NEVER run out of. You could also use solar panels on vehicles, be it on road, water or air. This can greatly reduce fuel consumption => not only does solar power have its own advantages, it also cuts down disadvantages of other power types. SOLAR POWER ftw

Although water is the one of the most abundant compounds on our planet, the supply of water for human needs is very low, so engineers need to be responsible for improving the supply of drinking water. One idea that I thought deserves investigating is the low-energy production of clean water using forward osmosis, where saline water is brought into contact at a selectively permeable boundary with a more concentrated solution with certain properties. The water moves by osmosis into the more concentrated solutions, but the solution has properties such that the solute will vaporise and be given off by simple heating, producing pure water. (Or equally I thought you could use concentrated nutrients solutions, to avoid neeting to remove any solute). I agree with whoever mentioned overpopulation problems, but the only ethical policies for solving that (i.e. limitations on no. of children) require the implementation of politicians rather than the ingenuity of engineers.

I believe that in order to become more sustainable we will need to harness solar energy. This is the only renewable energy source that is common everywhere. If we can create more efficient solar panels then we can reduce use of fossil fuels and lessen our carbon footprint. I also believe that the introduction of switchable glazing windows, which can reflect 90% of the suns rays, into homes and businesses can reduce energy costs dramatically. Also if we can implement solar panels into windows this would allow for much more renewable energy. Creating solar panels that are able to function as windows would allow solar panels to be in glass buildings, cars and homes.

Most of the "Grand Challenges" listed are ultimately the result of unsustainable population / demand growth. It is unscientific that this singular grand challenge "Overpopulation" has been conspicuously omitted from the list and it's discussion. The only listed Grand Challenge that comes close to addressing the grand challenge of "Overpopulation" is education. Which has been proven to lower population growth rates world wide. As engineers we have provided every society on earth with access to birth control only to see religion trump technology throughout the undereducated segments of the worlds population.

I have seen a few post mentioning this, but would like to state it again, explicitly. By focusing our efforts on advancing solar energy, wind energy, hydro energy, wave energy, geothermal energy, etc, are we not building a burden to carry in a few generations' time? Considering 'localised climate change', if we harness all our energy requirements from the elements, we might be affecting a balance that we as yet are not comprehending, nor will be truly comprehending until we have significantly changed that balance. Hence as much as fusion seems the old school choice, it seems like to more sustainable choice.

Complete Automation Based On Self-manufacturing General Purpose Robot Post-science provides the foundation for complete automation. Complete automation starts from the Self-manufactured General Purpose Robot with the ability of touch (coming safely into contact with an uncontrolled environment, as human, animal, and insects can do). The Self-manufactured General Purpose Robot is manufactured by itself and, with the ability of touch, can perform general duties and, thus, can replace all human physical labors, as machines have replaced animal labors in the Industrial Revolution. To finance the development of the SGPR (Self-Manufactured General Purpose Robot), the automobile industry provides an intermediate stage of application, which can justify the development cost. The main improvement will be the active shock absorber, which will give a competitive edge to the automobile. The active shock absorber will allow the car to travel on rough road and to make driving far less tiring when all the shocks have been eliminated. The active shock absorber will transfer the stress on the tire to the jumpulse mechanism, which is the key ingredient in preventing bounces. Thus, it will lengthen the useful life and reduce the manufacturing cost of the automobile tires. Most likely, the smooth ride could greatly increase the gas mileage. The feasibility of the active shock absorber has been experimentally demonstrated by mogul skiers, who can come down a bumpy hill in a straight line, while their legs go up and down executing jumpulses. Similarly, touch, collision without bouncing off, and prolonged contact in racket sports need the application of jumpulse. Post-Science Institute has solved the problem of touch, using the concept of jumpulse, an instantaneous change of force, while Isaac Newton and all the physicists since Newton have not yet fully realize touch is one of the most subtle problems in mechanics. A robot finger bounces off a surface like a ball bounces off a racket; jumpulse is needed in both touch and prolonged contact. To be completely automated, the Self-manufactured General Purpose Robot is constructed by the software programs which instruct the Robot to self-construct. In other words, the construction and modification of the Robot are done at a computer terminal. The robot software used should be completely automated, in particular, allowing completely automated updating from old to new versions with new functions. Thus, the other big innovation in complete automation is the completely automated software. Homotopy Graph Theory of T. L. Kunii will be useful in drawing the Robot. Homotopy Set Theory of Kunii provides an efficient mathematical foundation for complete automation. The solution of value of Hugh Ching will be needed to determine the value of the Robots. Richard Stallman and his army of Free Software programmers world-wide can rapidly convert the current partially automated to a completely automated software standard. Post-Science Institute would be willing to release the fundamental patent to the Free Software Foundation so that both the economic and the technical barriers to computer usage will be eliminated at the language level under the completely automated software standard. All people around the world over the age of six can start to program a completely automated All People Programming Language, which will communicate with its users in their native language or even graphics and sound. When the Self-manufactured General Purpose Robot is available for programming, everyone can have a job programming the Robot. For example, a car will be manufactured by simply push a button ordering the car to be manufactured. Today, in Japan there is already an electric fan factory, which is almost completely robot controlled. With the current financial crisis and with the automobile industry falling a victim to the economic downfall, our world has an opportunity to revamp the entire automobile industry, with public investment and, possibly, a world-wide initiative. Turning the automobile industry into a robotics industry might be the first step in the human destiny toward a completely automated technology. World political leaders should have the wisdom to see this opportunity. This huge project is blessed by the spirit of Ta-You Wu, who coined and defined the term jumpulse.

Use software engineering to provide for the following to come true: Capital markets are unstable. In the past there was no way to make them stable. But today we have computer power that can be used to make them stable. By using the greater computer power of today we can have a much higher turn over of capital in the capital market. This higher turnover will make the market harder to game or control and the market will no longer have the unstable run ups or declines. Who can change or control the market when say 20% of the capital is trading each day? So now that we have the compute power to provide for all these transactions that will smooth out the market how do we force people to turn over at a rate of 20% a day? Easy, put a cap gains tax of 0% (zero) on all gains of 7 days or less and put a cap gains tax of 90% of all gains of more than 7 days. The likes of Yahoo, Micosoft and/or Sun Micro Systems will give us the systems that will provide automated software agents to support turning over one's investments every 7 days (based on the specs you give the agent). A system like this will make the financial markets work as smoothly as the local fruit market.

Problem: Limited fresh clean water Solution: The transport of melted Iceberg water from the Southern Hemisphere to America. Engineering can help America by developing the simple technologies of gathering, transporting and distribution of iceberg water from Mega icebergs that have run aground in the Southern Hemisphere around the 57 latitude. Iceberg water is a renewable resources and recognized as such by academia and the UN. Melting iceberg water can add to Americas fresh water resources. Giant fresh water tankers driven by photovoltaic cells and other eco-friendly power sources can economically supply an endless need for fresh drinking water not contaminated by industrial and pharmaceutical pollutants. Recycled drinking water does not mean clean water, its just water that meets a lower standard. Iceberg water does not mean the continued wasting of water only the expanded supply and the possibility of better water management. Right now all we are doing is recycling not expanding our water supply. Technology can only do so much. We are slowly poisoning our self's with recycled water just like the Romans did with Lead pipes. Think about it!

I was told Mr. Raymond Kurzweil that reverse-engineering of the brain is impossible and unnecessarily task. There I will provide some details. “The plan is to engineer the mind by reverse-engineering the brain,” says Dharmendra Modha, manager of the cognitive computing project at IBM Almaden Research Center.” Reverse-engineering of the brain is impossible task. The brain is a dynamic structure. Dynamic of the brain structure is reflecting condition of a body where the brain is seating moment after moment. That will bring requirements to model a brain as whole in time short enough to make that structure pseudo static and link that structure to history of the body. That is important restriction. Brain structure is reflecting conditions of the body and did not have links to conditions in the environment. That is enough to make reverse-engineering of the brain impossible. Why that task is unnecessarily? So far no one attempt to build the human hand like printers. The same is with a brain. We have to build the devices with functionality of a brain. That is possible to accomplish on the base of a conventional computers and I know how to do that. Be my partners. Michael

Asteroid/Comet Impact Prevention is an "insurance policy" for civilization. http://legendarypharma.co m/jdf/impact.html In our Solar System, each of the planets is hit by large, high-velocity rocks at unpredictable times. A meteorite which is 50 meters (150 feet) or more in diameter can wipe out a whole city. A larger meteorite hitting the ocean would cause tsunamis, huge waves which could wipe out all of the coastal cities on the shores of that ocean. A meteorite several kilometers in diameter (more than a mile) would cause global firestorms, trigger massive earthquakes, volcanic eruptions, and tsunamis, and terminate human civilization and most "higher" species of life on Earth. If a comprehensive sky survey were in progress, a threatening asteroid could be discovered months or years in advance. If diversion planning is begun in advance, then the longer lead time could be used to send up a rocket to divert an incoming comet before it strikes the Earth. The expense of such preparations could be justified as buying DISASTER INSURANCE or implementing safety programs. We need to scan the entire sky every month. Long lead times are essential to successfully divert these objects to safely miss us. PARABOLIC COMETS (Long-period comets) are a special threat because: **They come through the Solar System only in once in human history, so we have no historical records by which to predict them. **They can come in from any direction including the north or south pole. **They come at extremely high velocities (50,000 miles per hour). **They are very large. **They could smash the Earth on their FIRST PASS through the inner Solar System, so we don't have lots of time to calculate their orbits. Hence the NEED TO SCAN THE ENTIRE SKY EVERY MONTH

Focusing on a few challenges can draw attention away from others. Any list limits knowledge of others sometimes unintentionally. My list, with clear statement that I think lists can be somewhat misleading wihout misleading being my intent, would add 1. Finding ways to stop collapse of cities into the soil or tunnels underneath in some cities 2. Finding ways so that people with disabilities do not lose rights under guardianship 3. Time travel through wormholes 4. Much further distance with space travel 5. Engineering home gardening and urban gardening when people need food without damaging farming agriculture 6. Decreasing launch costs 7. decreasing radiation exposure during space travel 8. Making space travel more affordable 9. Engineering ideas wthout making them so that ideas can be shown to eachother 10. Building bridges out of fabric so that they can be laid easily 11. more boats to more people to respond to water level rises 12. Controlling 9/11 like airplane use 13. understanding where missile technology is going and controlling the technology from harming others 14. Helping people not misuse products like I misuse or overuse caffeine sometimes through helping people understand results of overuse My list would include many more issues as well.

My comment concerns the lack of engineering and technology fields being selected by our current students. If the Administration wins its battle to cancel the Constellation program then how many young engineers does that affect when it comes time for them to select a program of study? How many students will choose other degrees outside of engineering and technology? There is already a lack in Aerospace Engineering graduates in the US today. According to current NASA Science and Engineering population statistics, nearly 87% of its workforce is of the age 35 and older. Of that 87%, 45% of those individuals will be eligible for retirement within the next five years. Young engineers who were motivated by space exploration and the dream of one day becoming an astronaut have just been removed by this Administration. How does canceling American’s spaceflight program improve our current education and workface gap in engineering and technology? It doesn’t! The number of predicted jobs for commercial spaceflight is less than the number of jobs that will be lost in canceling Constellation. Where do those young professionals go? By losing them you’ve just increased the time it will take to send American’s to ISS or beyond LEO. Where do you stand????

Post-Science Institute has solved the problems of completely automated software and touch, or collision without bounce. The following is an explanation of the significance and the technology of the software: Of all the advantages in software design, none is more important than the design requirement of permanence achieved through complete automation, a lifetime unfinished goal of John von Neuman, the inventor of the computer. Generally, a permanent entity will someday be infinitely more valuable than a temporary entity. In fact, permanence could be the only discipline of its own for computer science, and is the main characteristics of life science, which can be defined as the programming of DNA, the prime example of a completely automated software system. The condition of permanence is achieved through endless self-generation and automatic updating, which are necessary features of complete automation. Without auto-updating, nearly all the software budget today is allocated for software manual updating. The three main innovations in the completely automated software are (1) Universal User Interface, (2) Universal Computer Source Code, and (3) Universal Data File, the last of which has been thoroughly examined by the patent examiner for the completely automated software “Self-generating and Completely Automated Software System” Pat. No. 5, 485, 601 and only needs to be understood by technical people. Just the first two innovations should provide a convincing argument for the absolute need of the completely automated software. Universal Computer Source Code is simply integers from minus to plus infinity. The completely automatic manipulation of integers by the computer is the key to complete automation. The Integer is the natural language of the machine or the computer. DNA, represented by 1, 2, 3, and 4, is the ultimate example of Universal Computer Source Code. However, the integer representation of machine instructions is hard for the human users to remember. To minimize the technical barrier to computer usage, instructions should be explained and documented in human native languages or universal symbols. Universal User Interface is a tree-structured, numerical multiple-choice question format, which allows the human user to understand the questions expressed in human understandable expressions and the computer to handle the integer answers. Humans have been created with the ability to remember an unlimited amount of information through Universal User Interface, which groups similar items in the same branch of the tree-structured multiple-choice questions. This ability is related to the Human Associative Memory, which allows the human user to retrieve an unlimited amount of information from a computerized library catalog and gives humans the capability in their self-creation. The completely automated software will bring about a technical breakthrough of historical proportion, even exceeding the significance of that of the Industrial Revolution. In addition to bridging the gap between human technology and creational technology, the completely automated software, with the elimination of all the technical barriers in computer usage, will make the tangible contribution of full employment, one of the ultimate goals of economics.

In my opinion, there are hundreds of ways that mankind can use its resources in a more efficient and eco-friendly manner. It is more an issue of general knowledge and awareness by the public, coupled with favorable economical and political policies to be implemented by governments and multinational corporations. I´m particulary interested in the supply of clean water to the population, specially those who can´t afford it or are geographically distanced from mayor cities. A lot of these technologies already exist but are not being implemented either because there is a lack of budget or action by the government. Relatively cheap forms to accomplish this if by using surfaces or devices that capture the water vapor from humid air and condensate it to liquid form. This is a simple yet effective way to obtain water from the air (a source that is present in abundance). In addition to this, there is a huge development in water filter by using ceramic filters or activated carbon. It is important to take into account that these methods are not energy demanding such as reverse osmosis or desalinization plants, and could be supplied (transported) easier to populations in need, for example in the current situation in Haití.

"The biggest problem with this is not that we do not know how to purify water or help prevent disease, but rather that we do not have efficient systems to transport our help to these areas." 

I believe that the first step to answering these questions is to identify our most pressing problems. While there are many out there and many great minds to focus on them, I believe our most pressing human problems begin in the areas that cannot gain access to healthcare, clean water, and other essential needs. The biggest problem with this is not that we do not know how to purify water or help prevent disease, but rather that we do not have efficient systems to transport our help to these areas. If we can develop technologies that can be airdroped or distributed in more efficient ways, we can make all of the knowledge and resources we have more useful to all. This is one of the weakest links in the system and therefore I believe its one of the places we need to focus the most effort.

"It is vital that engineers come up with a way to mimic the Earth's magnetic field to protect Earth from solar winds, radiation, etc. "

My idea might well fit inside the pages of "Energy and Transportation: Challenges for the Chemical Sciences in the 21st Century" I propose the Glass Highway for America's transportation needs. A computerized electrical highway system that will power America's electric cars at 200-300 mph. The cars will be eco-clean & not even require a battery. The roadbed will be made of 50' sections of 2-3 foot glass (from melted sand) embeded with reinforcing, electrical conductors, a car slot, and communication wires. Massive machines will make the panels onsite and lay the 6 lane glass panels, 2 to a section, 6 lanes going, 6 lanes coming. The power will be supplied by 100 nuclear reactors built on each of our three coasts, to power America's future. Next to these will be built desaltination units, running fresh water by piping into the arid interiors of America. The nukes will also be hooked into the electrical grid to lower industrial costs, farming costs, domestic costs, and the glass highways. Overall, this project would eliminate our oil dependence, provide cheap consumer products, help us compete with the world, provide jobs, stop killing Americans due to exposure, and take our workforce to work at high speed uncongested highways. Thank you.

Title: On the quantum theory of Einstein's argument for the Analysis of 0. Introduction. The universe, in nature, natural phenomena should be similar, only the material universe, the formation of different density and structure of the different quality of performance, makes us feel amazing. 1. Nature of matter and energy. High and low quality material and the formation of high and low speed compression level of energy; promoting the synthesis of high-density material, decide the level of synthesis of high energy density material, high-density substance that is very low or lower the quality of countless particles of compression; promoted by the need to promote the same level of energy ; impact the level of decomposition of the quality of the material synthesized particles can be high-energy particles of synthetic material to lower the quality of decomposition of the small particles, and to promote particles of high-speed movement, high-speed movement of very small particles can enter the high energy density material, in collision of high-density material; arising from the accumulation of high-energy, at the same time, external high-energy to promote accumulation of material arising from the energy of movement of high-energy, high-density material and there must be space, ultra-high energy can be broken down into very low quality of the material particles, the level of energy; quality is endless. High-quality high-speed movement of material will be high-energy friction material into a large number of low-quality particles. From sub-atomic. Proton. Electronic components, neutrons from a number of electronic synthesis, the electronic energy by the atoms inside and outside the movement to promote. Pressure by the weight of the material compression; energy thrust; cold reaction; by Block, and synthesis of particles of different densities; structure to properties of atoms to the material. That is, the weight of the pressure of compressed high-density material is the weight of the material particles will be compressed in many high density, the thrust of energy that is the level of high and low quality of the material of the high and low speed movement of material particles of energy to promote compression, thermal expansion or movement of many particles of high-speed collision of the energy generated material composed of particles or the expansion to break down the material into a soft particles, condensation or low-energy composition of the material so that many static and rigid particles, the seat edge to promote material that is, when the particle energy must be blocked high-density substance. The level of quality that is composed of atomic particles to the most basic unit of material. The performance of different high and low quality of particles mixed into cells of different density and structure of the cells to the performance of different properties of plants; biological. Cell density of the material that is the quality of cell synthesis of the energy density of the material. High-density material, the more the number of particles needed to effectively break down a certain energy degradation, it is difficult or slow low-energy decomposition and degradation of high density material, low-energy decomposition of the material can be friction and low-quality particle surface. Low-energy particles that is low-quality low-speed particle movement, the collision can not be strong; friction particles of high-quality synthesis of high-density material particles and decomposition of energy to friction. Synthesis of the material structure that is formed between the material particles of the gap; gap, different high-density mixed particles, very low quality synthetic particles of different density and body-like particles of higher quality. High density of different body shape and different sizes of particles of numerous kinds, and different properties of particles of different properties of synthetic material. Light in different density and structure of the material to produce different colors, different properties of density and structure of how much the quality of the material can absorb light. Some high-density material; tough; high temperature, some soft; Some have toughness; Some are flammable, such as gunpowder; oil; iron and steel; the density and structure of plants. Crystal structure that is the gap between numerous particles, particles of low density between the meson, photon - particle easy to penetrate. Flammable material that is the synthesis of particles of lower density, low-density particles have a more low-density particles as a meson, easy to make high-energy particles flammable and low-density energy. Internal high-density material to high-quality, by the energy of the particle movement to promote the accumulation of more rapid movement of the particles can not be released outside the accumulation of high-energy, external energy to promote the accumulation of internal energy arising from higher energy movement. Such as external temperature and low temperature heating and cooling have a role. The star of the heat energy will be broken down into very low quality of the material particles, the energy limited the promotion to a certain distance, some by the energy level of the quality of the material to enter the collisions between particles have high energy, the energy accumulation of material by the external energy to promote movement and rotation magnetic field energy to other particles in order to capture higher quality, and some material with the release of the laws of celestial bodies to run to run, and some substances absorb their own magnetic field, and some other substances with a strong magnetic field to capture the stars. Particles composed of material for the production of heat and friction of the source, the weight of the pressure of compression and friction, energy and the friction of the thrust to promote (a large number of high-energy particles into the material with the friction; the formation of high-energy collisions). Stars within the field of high energy can not be effectively released by rotating the external energy to promote and stimulate the outer stellar particles that form a magnetic field, the solar system by the energy and the activities of the Milky Way, the Milky Way galaxy by the greater energy and the activities of ultra, ultra outside galaxies greater energy galaxies unclear. Galaxies in the deep air support there is for energy, the universe, there is also in deep energy for air support. Nature, ultra-high energy density; structural material performance, ultra-low energy density; the structure of the performance of the material also. The galaxy; objects should include the quality of the sphere of influence of its magnetic field. Uneven distribution of the material universe, there is the level of sub-stellar quality, high-quality energy generated galaxies - magnetic fields and the release of lower-quality energy dominated galaxies, stars and galaxies to promote the activities and operation of the energy that is released by magnetic fields and energy . Galaxies in the universe, that is, the quality of this release tiny particles of high-speed run to the far into the material by the formation of energy. The quality of the material universe, that is, the quality of tiny particles to smaller particles. 2. Conclusion language So Einstein do not think there is a certain density; structure; the quality of the particle, the particle level of quality is endless, with different densities of particles and structure of substances (particles), high and low speed of the formation of high and low quality of the material energy. On scientific cutting-edge issues, please consider this research, a lot of technological breakthroughs in natural science questions need to find answers from this article, I just love scientific principles, what is the exchange of views with me.

I think that we should stop using money currency and switch to a network( separate from the internet) of electronic debits and credits. This way crime can become completely preventable in a society that used this system. Fraud could not exist because of the system would be somewhat autonomous. We can have some sort of fingerprint ID which is how your account is charged and also how you are paid by your employer. We could have people who apply for business licenses to have a fingerprint ID scanner coupled with an ID card scan to ensure proper identity. When i say crime i mean illegal trades like drug trafficking. If we are not using cash it would be difficult and less economical for people to deal drugs because their business scanning system would show accounting errors or some strangely high priced items. Tax evasion would not exist either because all income is Automatically reported. It is a little bit of a fantastical idea but maybe something of the sort could help economic regulation.

Dear Sir, During my M.Sc. in Environmental Technology, I was given a class-assignment to tackle a global environmental problem in an innovative way. I chose “Rise of CO2 in the Air” because I had something to say on this. I wrote a plan which was low tech, can easily put into practice and where the whole world can come to play. The plan opens a new dimension to carbon trade for businesses, also the World. The outline was as this- Fast-growing trees assimilate CO2 out of air fast. We need to harvest these trees for their fast growing period in selected areas around the world. The harvest (dry hard wood is >70% carbon? And very slow degrading?) will be put away into caves, empty mines and faults- thus putting away atmospheric CO2 safely and cheaply for a very long time. After all, thousands of years old similar fossilized trees we use (oil, coal and gas) cause air CO2 to rise. Why not put back some? A Chinese saying is “Catastrophe = Opportunity”. Could we not witness the CO2 rise as an opportunity to store some energized Carbon (similar to currency?) for future use? Businesses may choose to grow & bury calculated numbers of trees each year to compensate for their extra carbon emission need. This plan will help developing countries come to terms with the world’s Carbon Trade agreement where they can even keep the harvest for themselves. This act means no offense to tree-lovers, forest-lovers or nature lovers. Only newly grown, purposefully, commercially harvested trees will be used, leaving natural forests alone. Scientists will calculate the numbers of trees required each year and decide types of trees to harvest for total sustainability (go bananas! ..may start experimenting with water hyacinth!). Desperate time calls for desperate measures! I know this is not ‘The’ solution, but as an Environmental Technologist I believe it has the signature of being a substantial part of it.

As an Army Officer who transported material across the world, I saw what modern transportation has done to rapid movement of large items. Instead of pipelines, dams, and reservoirs that have large environmental impacts, why not use the modular technology in conjunction with trains to move water from areas that are flooded or potentially flooded. A 60 car train should transport about 4.5 million gallons of water. The technology to pump water is there and used regularly. GE has hybrid train engines and with some additional electricity (solar panels etc), the engine could run hydrogen and electricity while powering the pumps for the water. Modular tanks are already produced or current sea/land vans could be lined to carry water. Currently there at least 40,000 unused rail cars. Multiple ways to link systems but it is a way to remove water before it damages and provide water to areas that need it using excess capacity or a specific set up.

I would just like to inform those that might be interested that my ideas for food safety would be to tell us where exactly the food was grown, and not where it was shipped from. Remember the strawberries a few years ago sickened several grade school kids and we were told they were shipped from California---but they were grown in Mexico. I have instructed my family, "We buy nothing from Mexico, period!!". Our Vice President said in an article in the USATODAY paper yesterday, said several things about how we should operate to make our food safer but never mentioned about where the food is grown, not shipped from!!!!!!!!!!!!!! Now, on another topic. In todays issue of the same paper they show a man telling us how much he liked his little electric car, and I have an idea about this! If you have an accident and bang up a fender or another panel somewhere, we should take a page out of the Nascar book and make our frames much stronger than we do today, then cover them with plastic fenders and panels that we should be able to buy from our 5 & dime store on the corner, or our parts store who handles things of this nature, Anywhere where there is competition to hold the price down. Our owners of these Nascars should be able to inform the makers of these panels where to get the best deals!! Can you see where these things could put people back to work, both in the plastics business and the installation and the selling of the part??? I don't know why we are stalling on these subjects!!!!

"I think the biggest engineering challenge is to have the profession recognised at its true worth to society. " 

I think the biggest engineering challenge is to have the profession recognised at its true worth to society. There are a few countries, such as Germany, Japan and parts of the USA, where engineering is revered as a qualification, and the profession flourishes in spite of many headwinds. In other societies in the developed world engineering is paradoxically seen as a basic skill, not worhty of recognition in status or reward. The paradox lies in the fact that the education system in these societies has been evolved to avoid the hard subject matter that is a prerequisite to any engineering qualification. Societies that recognise the potential of engineering as a profession, and appropriately reward its achievers, will contribute most in the discovery and development of solutions to the specific problems that your website seeks to prompt. I believe that the effort in this direction over the next decades will increasingly eminate from the east, which is a logical consequence of the fact that such a high proportion of the region's Kindergarden parents understand and pass on the importance of education, especially in the mathematical and science arenas. This aspect of glabalisation is one of the most positive I can imagine.

Solar Highways: Although solar fotovoltaic cells are a still less profitable way to obtain electric energy when compared with fosil energies, there's no doubt that they are an absolute trend for next decades and that this source of energy will be key for next generations' survival. In that particular sence, I think it could be a good idea to start exploiting right now the possibility to join in the same frame the construction of highways with the construction of solar centrals. A highway can easily support at its sides (and in the middle zone sometimes) a frame of solar fotovoltaic panels elevated for example 4 or 5 meters from the soil and with the possibility to rotate according to the sun position. This already well known structures could be replicated in theory across all the highway of any sunny zone of any country in the world. The idea is to take advantage on the fact that a highway is a sunk cost with a permanent impact and this impact can be additionally used to support another sunk cost with another permanent impact. Possibily, there could also be construction savings. Furthermore, it would be easier at the begining to attract investors for a solar central if it is part of a surelly profitable toll communication way, than otherwise. Business could be made for example with a partnership between an energy company and a highway company. The main point of this idea is that this way the presence of fotovoltaic solar energy arround the globe could be boosted just because there's an intense need to built or renewal highways everywhere, specially in emerging economies.

It allows to use any brackish or seawater for agricultural irrigation (one of the major use of water) with minimum investment. It will allow to return millions of acres of fallow land back into production and free valuable drinking water for population.

Please look abstract my research A hypothesis is proposed concerning the cause of the origin of universal gravitation. This cause consists in a system of the ether vortex rotations. Physical and mathematical grounds are described and the formula for the determination of the space gravitation forces is deduced. On the basis of the vortex gravitation, the principles of creation and existence of the celestial bodies are shown. Methods of the use of the vortex gravitation properties for the space flight projection are proposed. My theory can to explane origin of gravitation, anomalies and accelerations space flight of satelites "Galileo", "Rosette", "Cassini". My theory can to make flight on Moon and other planets on 25-30% cheaply. My theory can to explaine cause of THE ELLIPSOIDAL SHAPE OF ORBITS and OF EBBS AND FLOWS. My article was published on journal http://jvr.freewebpage.or g/TableOfContents/Volume2 /Issue2/2-2.html I would like to receive your response with your opinion and your help to research its principle.

A bridge between physics and engineering in the field of nanotechnology can lead world to meet challenges like energy storage, environment purification and treatment of chronic diseases. For instance nano-TiO2 is proven to have been a great soruce of gas cleaning, energy storage and treatment of diseases like cancer. Production of nano-materials on larger scale can produce a great revolution in the engineering world.

I think increasing the efficiency of biofuels, in the harvesting (or collecting, when we think of used cooking oil, for instance), processing, tax incentive, government laws and aid, and so on, is a challenge for this century.

"Refineries for used cooking oil and other materials, that can be processed into bio diesel, could be built." 

We need to find ways to produce biofuels economically on a large scale. Refineries for used cooking oil and other materials, that can be processed into bio diesel, could be built. It would solve two problems: how to dispose of used cooking oil, and how to provide cleaner, Petroleum-free fuel. Also, developing cellulosic ethanol and producing hydrogen on a large scale from water are other methods for providing renewable fuel that need to be further developed. Another Idea involves using plasma disposal units to dispose of our municipal refuse. I don't know why this technology is not used more widely

"Efforts to create photosynthesis artificially should certainly rank with sequestration of carbon dioxide as a challenge." 

1. I have serious doubts that sequestration of carbon dioxide will pass a cost-benefit test. Nature deals with it by using photo-synthesis to free the oxygen and use the carbon for building plant material. Effort to create photosynthesis artificially should certainly rank with sequestration of carbon dioxide as a challenge. It would be a lot easier to bury the resulting solid material. 2. If hydrogen is used as an energy-storage medium, the next question is whether it would more effective to ship the hydrogen to points of use, or to use it with fixed-base fuel cells at the point of creation and to transmit the resulting electricity to the points of use. I doubt that hydrogen and fuel cells in electric cars will prevail, so I bet on the second option. 3. Unspoken in the very meaningful challenge report is that population control lies at the heart of many of the problems addressed. The application of engineering to the reproductive process is certainly the equal of possible engineering actions to other biological processes. The fact that there are religious and other sociological barriers to the application of any results of such research and development should not prevent the search for better methods for dealing with this issue.

There remains humanity's unflagging acceptance of the quasi-engineering challenge, that suggests Mother Earth is incapable of satisfying each and every need of her beloved inhabitants. Dismantling this roadblock will involve a paradigmatic shift, not unlike any other technology application, requiring techniques of behavior engineering, currently in vogue. The overarching belief in scarcity undermines innovation by virtue of its unquestioned acceptance in human reasoning. There is a fantastic abundance of electrical energy pervading our Solar System in the form of electric ring currents. Our challenge is therefore, to activate, arouse and awaken the bountiful creativity long repressed in the human mind. Once that is accomplished, it will become obvious that scarcity has always been the mere figment of the imagination.

Please consider adding another Grand Challenge focused on complex adaptive systems. A few thoughts regarding a complex adaptive system grand challenge: This framework was influenced from work underway at the Boeing Company and the book "Complex Adaptive Systems" (Miller-Page). Research questions to consider: Study Industry-Academia and Governments as complex adaptive system: What is it that enables the their system to sustain productivity aggregate patterns through technological. For example in the aerospace industry, advanced material and product lifecycle management and global business partnerships i.e., distributed  global business shared risk-shared value investment model?  How robust are these heterogeneous social system? What is the capacity for dynamic adaptation? What policies and procedures enable adaptation, how do they propagate through the social network?  What is the effect of internal  external policy decisions, technology and global pressures change? How do these decisions support the goal oriented behaviors of social agents? (Contagion phenomena)  What computational models can we employ to better understand the Boeing Innovation culture, as a complex adaptive system?  What are the commonalities among adaptive agents (leadership, fellowship and extended workforce)? Can we distill these behaviors into prototypical adaptive behaviors; can we leverage this insight to shift lifelong learning strategies? Can we identify the level of sophistication and enabling conditions?  Social Niche Construction: the new business model fundamentally altered the internal agent behavior through exposure to global external agents and cultures. Can we model this new operational mode and understand how to leverage the combined intellectual capital generated from this diverse perspective? Social worlds: This new model presents a opportunity to shape influence global behaviors by shifting the balance of local and regional control. How is this accomplished by agents within this global environment? How does this decentralized  centralized balance occur, how does this impact agent behavior i.e., heuristic business modeling for the benefit of the collective system goals?  Social agents receive or acquire knowledge; the information is leveraged against a schema, processes and acted on. Within the social network, how do agents access information, what is the level of fidelity, how do they direct their acts toward optimizing the solution space?

"Every new highway project can cheaply and easily integrate more green practices with proper research and development. " 

It is vital that every engineering discipline do their part to advance the quality of the world we live in. I believe one of the most plaguing issues facing my field of engineering (Civil) is an unwillingness to accept the challenge to advance to a higher level of environmental consciousness. Every new highway project can cheaply and easily integrate more green practices with proper research and development.

"Several of the remaining challenges can be solved if we have access to clean power. " 

In my mind, the greatest challenge is the generation of cheap, plentiful power. Several of the remaining challenges can be solved if we have access to clean power. This can come from many sources but ultimately all power on earth originated with the nuclear fusion reactor we call the Sun. We should look to solar and nuclear power as the primary sources for this clean energy. Engineers and scientists should also take a larger part in developing public policy. In the US, I would go so far as to suggest the generation of a third political party - the Engineering Party. Let engineers do what they are trained to do - solve problems - in the political arena.

Next challenge: engineering science figuring out how to integrate the working members of those families to productive chains with optimized state funding. Maybe even showing how they can be involved in the obtention of their energy or water.

"Could we tap into volcanic magma and create blowback steam in the casing after pumping high pressure water through ceramic high temperature pipe? " 

Could we do more to turn our earth"s volcanos into geothermal furnaces? Could we tap into volcanic magma and create blowback steam in the casing after pumping high pressure water through ceramic high temperature pipe? Ceramic pipe is also used for water jet cutting? Shouldn't we be using the extra heat of global warming from as far down as possible? Turn ocean volcanic activity into hydrogen and oxygen mines via steam turbine powered remote electrolysis plants. The same ships that haul Natural Gas could haul Hydrogen. Come on people those zits to big for us or what? If the source of the heat of the magma is from a large concentration of high density and radioactive minerals "piled" up at the center, it may be at least part of the source of global warming and shouldn't we be trying to use it? Any chance some of our deep wells could turn into volcano's, if the heat from beneath is expanding?

"Mostly, to the general public, this list could represent the ideal direction in which humanity should progress. " 

Hi, I am also an engineer, and I like the idea of having these grand challenges listed. It serves a source of inspiration to help student engineers choose areas of study as well as to giving senior engineers something to consider for their career. This list also hopefully servers as an inspiration to business leaders looking for market opportunity areas or directions for R&D efforts. Mostly, to the general public, this list could represent the ideal direction in which humanity should progress.

Consider placing sol-stationary solar collectors in series between the earth and venus. The collectors would be convex mirrors (~3 ft. in diameter) teathered to reflective foil parabolic parachutes (~500 ft in diameter) with a hole in their middle. The concave side of the foil would face the sun, reflect sunlight to the convex mirror which would then focus it earthward through the hole in the foil. Dozen of these assemblies could be placed in a line so that the final beam could be dozens of megawatts of thermal energy. Each assembly would be held into place by the balancing of the solar wind force pushing the assembly spaceward against the gravitational force on the mirror. The nearer an assembly is to the sun, the lighter the mirror and or larger the foil. It is this opposing force dynamic that would allow an object that is closer to the sun to maintain the same rate of revolutioin around the sun as the farther away earth. These concentrated beams of light could be used to protect crops from occassional freezes, melt ice for fresh water, make battle zones temporarily uninhabitable, optimize climate (like evaporate sea water channeled to death valley so that Utah, Nevada have higher air humidity), run power stations on earth, and possibly disrupt hurricanes. Since the assembies could be 'sailed' by feathering the foil 'sail' they would only consist of a mirror, a small solar collector to run servos that tug on specific wires of the 'parachute'. In theory, mass produced assembly could be produced for a pitance. One last thought is the climate effect. Blocking sunlight and then channeling it for power reduces heat input to the earth as well as reducing heat retention.

"Make solar energy affordable" is inadequate; transmission and annual-scale firming storage are necessary for "solar" and other large-scale stranded renewables. Electricity transmission provides no affordable annual-scale storage. We find that gaseous hydrogen (GH2) and anhydrous ammonia (NH3), gathered and transmitted and distributed via underground pipelines as C-free fuels, firmed in solution-mined salt caverns (for GH2) and surface liquid "atmospheric" tanks, would allow us to run the world on renewables. See our papers, posters, and conference presentations at www.leightyfoundation.org /earth.php We must think energy systems, not sources. Now we need to build pilot plants to discover and demonstrate whether these GH2 and NH3 renewable-source energy systems are technically, economically, and socially attractive. Thank you.

It is a fight we ought to make collectively challenging each other and exchanging innovative as well as existing ideas. We get caught in the innovation realm, while leaving a lot of proven technologies that need breeding grounds on the table.

The only way engineering can advance is if we focus on what is actually possible within the realm of what we already know, I have read alot of the previous comments and reading some of them I actually lost a little bit of hope for humanity. Just a couple that stood out in my mind, Transmitting energy wirelessly is physically possible, but you cannot control it's direction, it is well known that electricity follows the path of least resistance, in an atmosphere resistance is homogenous, this means that the energy goes in all directions losing more and more energy to both the fact that it is spreading in a spherical manner, and the extremely high resistance of air. basically what I am saying is that you can transmit electricity through air, but it would be amazingly inefficient and would probably kill everyone in the room. the other proposition that I remember is the idea that we could make bacteria that consume CO2 and produce water, I would recommend a basic chemistry class to this idea's author, Carbon and oxygen do not make water. Hydrogen and oxygen do, so in order for these bacteria to produce water they would need to be supplied with hydrogen and probably produce pure carbon as a byproduct, not a terrible idea altogether until you consider the energy that has to go into the production of hydrogen it ends up being a wash, with today's energy costs its just not economical to use hydrogen fed bacteria for capturing carbon. but at least these two authors gave an honest effort, albeit a very idealistic attempt, they are still far superior to the single sentence of one "d.venkateswarlu" from india, this kind of pessimism is not constructive in any way, and if you want to continue making statements like that I suggest you change fields, literature perhaps. Overall i like the comments that are on this site, it shows that people, especially young people still have ideas, and still want to change the world for the better. With just a little bit of guidance these ideas could be pointed in the right direction and actually do some real good, for example, if you want to transmit energy efficiently, look into high temperature superconductors, if you want to work with bacteria to improve the world, look into genetics to make bacteria that produce new pharmaceuticals, I hope that my remarks on the two previous ideas did not discourage their authors, I only want to provide some of my previously mentioned guidance. and thats the end of my rant :P

Engineering is not always necessary to solve the perils created by human kind itself. A general approach may bring a drastic change. I, being a student of chemical engineering, strongly believe that, small changes like avoiding packaged drinking water(to prevent exposure of plastics to environment) may be considered one of the step. Figure this out, a used plastic pouch has an approximate area of 0.005 sq.m only. Imagine that a small location of population around 100000 causes an exposure of around 5000 used bags per day. The area for heat transfer with atmosphere available is thus 25sq.m. Summing up for a city of population around 500000 and considering the average consumption of 200000, the area is 10000 sq. m. WOW! almost equal to 2 football grounds. These statistics are for a single day and a single location. Now consider usage in whole world, and u get 1000s of football ground exposed to amosphere directly to exchange heat. a temperature difference of 5 degrees celcius and avg conductivity of 2 will give 100000 watts of heat per day. Now u can imagine the HUGE effect of a small change.

I might be young to have a respected opinion, but it's one that I believe will change how we engineer the world. We need a new form of transferring energy. A world without wires would help our environment, resources, discoveries, and how much energy we could access. Transferring energy in large quanities could lie in our information technology. Just like we can transmit images and sounds wirelessly, we could engineer a way to do the same with energy.

One important way that Engineering can improve the world, is to have an epistemological sense of itself, i.e. to know the bounds of problems it is equipped to potentially solve. Some problems are better addressed through social science, focusing on innovative applications of existing technology. For instance, virtual reality is listed as one of the 14 challenges, however online social networking applications such as Facebook, which are certainly some of the most compelling forms of "virtual reality" existing today, are not mentioned. Technology is a partial solution. When Engineers work in tandem with social scientists and social innovators, better solutions emerge.

If food habits can be changed there is enough water for providing safe drinking water to all the population in the world. For instance one kg. of paddy consumes about 4000 litres of water. This coupled with minimizing transmission losses would help meet water needs of the world. Then the issue to be discussed would be equitable distribution of water. Politics enters here. We need statesman here not the run of the mill politicians whose agenda most of the times is for 3-5 year time span. Therefore the solution is not in finding engineering solution to the current problems(these will be replaced by new ones once they are solved) but engineering the emergence of statesman to lead the nation states and the world. Is this a tall order?

People are always talking about two thing: global Warming and provide clean water to the world. The two don't really have any thing in common but I recently came up with an idea which will kill both birds with one stone. humans around the world have been creating carbon collectors a lot recently which store carbon underground for all eternity, well I thinking maybe humans could Bio-engineer a form of bacteria that breaths or eats carbon dioxide and the creatures waste product is water. we could create billions of these creatures in carbon collectors and when they've eaten all the carbon, fresh H2o awaits to be filtered, then drunked. It sounds a little crazy I bet but for every ton of CO2, there's 250 gallons of water, and given the billions of ton of CO2 we have created would mean hundreds of billions of gallons of new water would be available for mankind.

I propose that further involvement is taken into the consideration of materials science in environments not that of earth. One subject that has recently captured my attention is the rust on Mars. Now, think that for rust to occur, the process of oxidation and reduction needs to occur. Well, if one looks at the chemical composition of basic iron (III) oxide, you can see there is H2O included. Back to Mars: if there was ever found a reliable method of seperating this water from the hydrated iron oxide (a de-oxidation, if you will), then we could very well be producing water and oxygen on Mars -- a very good proposition for Space exploration/colonization in years to come.

"...governments of first-world countries should start making new desalination plants and distribute the water to third world countries..." 

I was thinking to give access to clean water throughout the world is this: governments of first-world countries should start making new desalination plants and distribute the water to third world countries and use the water to replenish reservoirs with the water [the reason why I think it would be best to replenish reservoirs rather than just give people the water is because the reservoirs are where the water evaporates into the atmosphere and begins the water cycle which would be better because it would feed crops better, gives nature some of the water for plants and animals, and distribute the water much better.]  I'd also a have people make sure that theres only a certain amount of water each person or farm would get; making it much more sustainable. last but certainly not least, I start making a wide range of water plants that recycle the sewage water, filter and clean it, and redistrubute the water [they already do have a plant located in orange county, California that recycles sewage water but It would be good if we started making lots of these plants.] if we did all these things, we would save millions [if not billions because a third of our world lacks clean water.] of life's, and stop world hunger.

Engineering, reviewing current trends, will lead to more efficient technologies. These technologies will not be enitirely new ones, but improved versions of the ones we use today. I conducted a research lately on the future of aeronautics. I designed a plane for the aviation needs of 2058. During the research I noticed that current technical efforts were directed on improving current technologies rather than making new ones. For example, the research on the propulsion systems is meant not to come up with an engine with an entirely new mechanism, but instead to understand the operating principles better through computational engineering and then only to 'modify' current designs. By studying new concepts like the Boundary Layer Ingestion (BLI), engineers are working to change the current propulsion sytems by varing nozzle/intake geometry, engine placement, and bypass ratios, so that the utilize BLI efficiently. The results are better engine configurations which can be validated without largescale design revisions. This means that technology can be improved significantly to meet changing demands with minimum wastage of effort and, most importantly, money. Engineering in the coming years will improve existing technologies with moderate capital investments, benefiting the developing economies in particular.

"What would we DO with this free and abundant energy, if we were to have it NOW?" 

Assume, for a moment, that we found the perfect, everlasting, abundant, and totally non-polluting source of energy. Assume also that this energy was freely available, compact, portable, very cheap, and simple enough for anyone to harness with simple/cheap off-the-shelf equipment. Also assume this energy would be available to all, from the poorest-of-poor to the richest-of-rich, as it is neither patentable nor could anyone own it's source, as it is everywhere. Assume also that this energy would be capable of energizing all of our current machines of the world many times over into the future, ad infintum...

Now, this hypothetical 'perfect energy' may one day become a reality. But the pertinent questions we must ask ourselves are these.... What would we DO with this free and abundant energy, if we were to have it NOW? Likewise, what would 'they' do with it? What are we doing NOW with our CURRENT cheap energy? (Oil is about a dime per cup, and a couple gallons of oil does the work of one man-year of labor.) Again, what are 'they' doing with it? Extrapolate, if you will, from our current energy needs and wants, on into our future needs and wants....Include our children's needs and wants, and their children, and on and on. Include all the nations of the world. Include 'them'... Would we not overpopulate, overpollute, and overextract everything of value within this once precious Earth? If one were inclined to say "No", then consider how one could prevent someone else from saying "Hmmm...Yes, why not? (We'll just lobby!)". Are we/they not destroying our planet now with cheap oil? Also consider the 'darker-side' uses of this perfect energy, as in the utilization of this cheap, compact, and portable energy as a 'not-so-friendly' gesture of general disagreement. Again, would any Earth-Life survive? Do we really need what we so desparately want? Is it for the good of FUTURE Mankind, i.e, the child, and his Earth-home, that we find this energy? Judging by our current uses of energy, some would think not.

"Our society today demands more accurate modeling of our world..." 

Throughout civilization's advancement, modeling of what is 'to be' has allowed engineers through simulation to experiment and optimize solutions that have advanced modern society. Our society today demands more accurate modeling of our world so that better decisions on how things are to be and how these things will behave can be explored. Advances in modeling of electrical infrastructure in particular are critically important, as is the lean management approach to the data and information required to make better decision on this decaying infrastructure. The application of Machine Learning in making better decisions on predicting potential issues with underground infrastructure is one such example of better math to enable better decisions. Models of infrastructure using version 31 of old Fortran computer software models will not allow us to make the advancements we need to migrate to the electric economy that can enable the significant use of renewables and demand side management.

I read somewhere that the possibility of immortality was actually possible....really? I guess I wouldn't be too surprised, with all of this new and amazing technology, however, when and how would you go about this? I've heard about transfering brains into computers (kind of like the matrix...seriously!), cryonics (or something like that), and a way to manipulate genes in order to stop aging in the body, or at least prolong youth untiil some kind of replacement or transfer can occur. I also understand that this process could probably take place within the year of 2050 -2080.....interesting stuff to ponder on :)

A large volume of water is used for power plants as a heat exchange medium. Some experimental designs for a new generation of nuclear power plants use Helium as a heat exchange medium. I was thinking that water could be saved for drinking and agriculture by switching power plants to use helium gas as a heat exchange medium. It has a much lower boiling point than water so I was questioning if it would be even better at generating electricity.

With respect to some the comments on this page, it's easy to jump to solutions instead of identifying the challenges.

I recently read an article about ozone pollution. There were so many discussions about environmental limits. If I remember my basic chemistry, ozone is 3 oxygen atoms bonded. It occurred to me to develop a [catalytic converter] of sorts for smoke stacks. My theory was to have a device to break up the ozone molecule and let it recombine as oxygen. I thought that an electrically charged plate (solar powered, wind backup) would satisfy the valence shell electron and break up the ozone, then send it through a gradient to allow the oxygen ions to recombine.

Engineering community, The article "Introduction for grand challenges for Engineering" was well written. Onother couple of topics left out. Harnising the hydrodgen fuel cell cheaply. Some company's have claimed they can cheaply crack water (into hydrodgen and oxygen) by using nanotechnology. The most important one left out is an American issue all to itself. The U.S. is failing to produce large number's of engineer's which will leave a major talent drain in the U.S. For the U.S. to reclaim/maintain it's technology and innovation, bringing Engineering back to the forefront in the U.S. must happen or we will lose (our losing) our hold on being a technology leader. This change must occur fast. China is pumping out 650,000 engineers per/year form college and the U.S. is only bringing 75,000. Accoring to world ranking, the U.S. colleges are rated 17th in the world, wheras, a half a century ago, we were 1, or 2 in getting a quality education. How do we convince our Government/kids/parents, that engineering and science are the needed fields to be in. The field that will allow the country to pull out of the slippery slope the U.S.is currently on? History, has told us time and time again, that technology will always be a major layer as to how well a country prospers or suffers. How do we (as U.S. citizen's) make the change of the failing system and get innovation and engineering back to the forefront? Sincerely, Mark Webster Kokomo, IN

I have two suggestions for the scientists and engineers: #1 - If you can simply design wings for the human being so that we can fly like birds. If it can be done, we don't need to worry about building million miles of road networks, we don't need to live in congested cities and no need to worry about CO2. Most of todays problems will be solved. This idea might be little too far but hope this can be done in the near future. #2 - If we can design human body through genetic engineering (by inserting plant genes) to have chloropyll in the body which can perform photosynthesis in presence of sun light like any plants do. People won't suffer from hunger, malnutrition, food safety, etc. I hope these two are not that difficult achieve in the near future. Best,

Engineering has to improve statistic methods. Most decisions are made based on statistics that do not represent opinions or characteristics of man or any other research subjects reliable. From this it follows that we have to improve the engineering of statistics. The (especially in Germany) popular idiom "I only believe in statistics that I doctored myself." demonstrates the current situation. decisions are like steps upstairs, it's dangerous when the bottom of these stairs is not firm and reliable. The improvement of engineering of the statistic methods has to go along with all the other challenges.

I have gone through the Grand challenges. I belive before creating a new era or innovation better to look backwards and bridge these new challenges where it can fullfill the earlier engineering developments. In addition every invention has two sides such as Bad and Good, the magnitude of the direction is decided by the mob/decesion maker. So this is the time for challengeing the past innovations rather than finding new challenges. I also belive the challenges posted are shortlisted from human evidencing disasters earlier times. I belive the biggest challenge is to the engineer life cycle of a citizen.

GRAND CHALLENGES What are the grand challenges for engineers? Engineers, today and in the future, need to fully examine our design & construction processes to determine the impacts (both positive and negative on all life forms) for the next 7 generations as a guiding principle (source: the Iroquois Confederation). Principle Declarations I. We must reclaim our humanity through creatively imagining the future with everyone (every being on this planet is a stakeholder -- not only our clients, employers, and local ecosystems and local human communities). II. We must change our engineering foundations from Newtonian/Cartesian thinking (mechanical-based, disconnected, separate, reductionist analytical theories and laws) to integrative and complementary, fluid, circular, holistic living systems-based, connected, conceptual theories and laws. We can not change the world for the better until we change the way that we view the world. III. We must choose peace and not war. We must decide to use our intelligence to create a peaceful, fair, just, and humane world. We have participated way too long in Wars where we systematically kill ourselves, therefore we must begin the process of healing and saving ourselves. We must support and engage in research efforts that enhance everyone's humanity, imagination, creativity, and overall well-being. IV. We must support ethics by not condoning corruption and other unethical behaviors in our business dealings, pursuits, research, etc. V. We must examine our design and construction processes through life cycle ecological & temporal synthesis (geologic time constraints, internal and external costs, ecosystem health impact, human health impact, overall global impacts - biogeophysicochemical cycles, etc.) rather than life cycle analysis. VI. We must develop frameworks similar to the Cradle to Cradle framework created by the MBDC. VII. We must develop energy effective rather than energy efficient products (source: MBDC). VIII. We must work with the general public better because solving the world's problems and avoiding creating future problems requires working in true interdisciplinary teams. IX. We must continue research efforts in the field of biomimicry. X. We must uphold ecological health systems [ecosystem health & human health (biological, economic, emotional, social, spiritual) in our top lines rather than our bottom lines (source for triple top lines: MBDC).

Engineering has a great opportunity to not only advance the cutting edge of advanced technology, but more importantly to find ways to ecenomically bridge the divide between the richest of nations and the poorest. The great divide is certainly an engine for conflict which will continue to drain rich nation's wealth on national defense. An investment in the future will find ways to reduce the wealth gap through the building of infrastructure in the poorest of nations. Through technology improvements that can reduce the cost of current technology and a forward thinking policy to fight the root conflict the world can be made much better via engieering and technology.

Engineers need to participate in carving the future of society. They should take steps to grab political power and spend on hour a day with non engineers.

First and foremost I'd like to express my thanks for at least having such a forum available where people can express themselves in regards to these issue. now I'd like to take this opportunity to say a few things about the issues brought to the table here. What is the purpose of this site? to inform the public about what could be done in the future? what about today. The time is now!! and it's all the time we get. no matter how much planning or debating or wishing is done, we are still wasting the only time we will ever have to do the things we're not doing right now. stop the crying over spilt milk and let's get off our butts and do something. I am so tired of hearing about the next big breakthrough in whatever field we're talking about. I am 100% positive that if we wanted solar energy to be the main source of electricity for our urban centers it can be done with nothing more than will power, which costs the taxpayers nothing. efficency is the tag line for solar energy. we need more effiiciency. how efficient is the destruction of the ozone layer? let's just start using it and worry about efficiency as we grow with the technology. sound evolutionary to you. natural maybe. The promise of making a killing in the fiels of solar energy is the only thing holding it back from benefitting all of us right now. money is the greatest excuse those who have it and control it can use to deter those who don't have it from achieving their goals. What it takes to get things done isn't monetary in nature. human beings survived for a long time without money and seemed to get things done in ways we will never truly know or understand. I'm not saying anything about getting rid of money or using a barter system, but human beings make money from paper made from trees. the importance comes from that which we put on it and it has gotten to a point where we have fooled ourselves into thinking money controls us, therefore those who control the money control us. well I for one am not sacrificing my life so people can have gold toilets, SUV's and flatscreen tv's. Food and water maybe! the basics. this is where we need to go. we need to supply the need not the demand. If I demand 40 virgins and all the beer I can drink. do I have to go bomb a building to get it in my next life? or do I just sell you oil to burn and call it a "prophet"-able day. educating the young is a problem only because the young will conquer the old and create a new system of thier own which the older generation will resent them for having when they did not and could not create themselves. the jealous side of human nature. so until the old school thinkers can benefit equally from any new system (monetarily as this is the only thing woth having to them) more war and strife are looming to stop any new system from emerging. I am also 100% positive that on the day I was born, when mankind was sending it's first explorers to set foot on another body in the universe (the Moon, JULY 16, 1969) the money spent to do so was alot more than it would cost today. but of course inflation / greed has increased substantially since then, so the costs of even repeating tasks that have already been accomplished would cost more. this is not how nature works but this is how society as we have allowed it to become works. nature is our only teacher but again the experts know more and know better. not just in the field of space exploration but in every walk of life? The mindset of the people in charge is that they deserve to be in charge and make decisions for the rest of us who can't make decisions for ourselves. well if asked I'm pretty sure I can make any decision I need to make given the proper information. this is the next point i'd like to make. information is the root of evil not money. those with the information always use it to better themselves which naturally makes it worse for others somewhere. simple math to illustrate. if you have 50 apples in your bag, that means 50 people can't have 1 apple each. is that simple enough, can george bushites understand that kind of simple and true logic? there will be no true democracy until the commmon man can have his own voice heard instead of an elected official whose voice is bought and paid for. this is the future of the communication network evolving out of the internet. a forum where true democracy can actually raise it's head and proudly proclaim to be the voice of the people by the people themselves. No small closed off groups to manipulate us anymore. voting will be real and meaningful as it has never been in the past. We need to change our ways of thinking about life, about society/civilization and about the future. we leave a splintered and corrupt legasy of abuse to the planet that spawned us all. We have already condemned our future generations to a life of slavery just to undo the damage we've done. yet all we can do is praise ourselves for the technology we have and the lifestyles we lead. we are the most useless and worthless society yet to emerge due to our lack of connection to the real world we live in and what's worse is we're destroying it. when was the last time you said no to buying gas which you know causes wars and pollutes the atmosphere? yeah I thought so. I don't own a car and won't until they come fully electric. you think this is a long way off but it's actually a long time gone by because electric cars have been around since before the combustion engine. those in control felt it was better for you to have gas guzzling cars instead. for an answer to the question why, just look at the "president" a dumb as a stump cowboy who thinks because he has money and power (gained from your consumption of gas) that it is somehow his right to make decisions for the rest of us. this guy wasn't even elected to the office and you're still allowing him to rule you like julius ceaser. is this guys word the best that you can offer the world? if so the US is headed for a major fall on the order of the Egyptians, romans, and especially the Neanderthals. Economies can't survive being based on commodities which come, go and run out. ecomonies need to be based on those who are affected by them meaning people. nothing can run without people. people buy and sell. people consume goods and services. people are the most underrated and under used commodity out there. we all need to eat, we all need to drink, we all need a roof over our heads. and we all will do whatever we have to do to get these things whether it's work 9-5, rob, cheat, steal, or kill. I say base the ecomony of the world on the simple principles of feed and house, and let the rest sort itself out. We have people better suited to run the free world than george bush and the like. or do we just want to let the wild west riegn forever and have things sorted out in a manner man can only acheive with a handful of bullets. If that's the future we're going to allow, I'd rather go back to my birthday 38 years ago when man had at least a hope of better things to come. in not so short, ACTION NOW is what we need to focus on, not questions like "What are the engineering challenges we need to focus on?" don't put off until tomoorow what you can do today because tomorrow isn't guarrenteed to any of us. and I mean that literally. we will always be able to ask questions of what to do but let's get something done now that we engineer to be "UPGRADABLE" in the future. We've been asking the wrong questions for far too long already and these questions are not going to go away even after we find the answers, a whole new set of questions must arise. this is change, and it rules the universe not your local goverment no matter what they try to tell you. this is where your fight is, not fighting change itself but fight for the changes you know to be right, are you up to that challenge?

Dear Fellow Engineers, We have seen so may revolutions including Industrial, Automobiles,Information Technology ,Space and what not. We have missed to solve the problem of shortage of safe & good water. It applies to Drinking as well as for Agriculture . We have forgotten that Nature [ or say GOD ] has given us on this earth more of WATER only. That too with a safe pollutant resistant as Common Salt .Even if it is salty it is only water which can be desalinated. The question is how to economically desalinate this? When the whole focus is on it, solutions can be easily found. We can find ways to get Good Water and Hydrogen from sea water to feed all the populations right from Plants , Animals and Humans. May be ,hydrogen as a bye product will be the best replacement for the Petroleum. The whole world is facing inflation due to the so called 'PETRO - GOLD ' pricing . Let the best of our Engineering Brains spend their energy with the support of the International Donors / Sponsors to break new grounds There is a famous quote from an Indian Swamiji as follows: 'THE PROBLEM IS YOU THE SOLUTION IS YOU ONLY' Let us jointly solve this problem. .The problem is only SALT. Desalination at an economical process. I am confident that the Engineers and Scientists who made Mr Neel Armstrong to land on the Moon and return safely will be able to solve it - given the right direction and resources. True to his words 'LET US GET A GREAT LEAP FOR MANKIND BY TAKING THE ABOVE SMALL STEPS' Social Medicine Scientists and Agricultural Scientists will agree that better drinking water will bring in better healthy individuals and better plants/crops. And environmentalists should take care of the GREEN OCEAN in this endeavour. WISHING THE BEST WE ENGINEERS MAKE THE WORLD

One challenge not mentioned in the list is that of finding a way to reduce the human population of the planet, and maintain it at a low, sustainable level, preferably without resorting to nuclear war or a global fatal disease epidemic. Our other scientific and engineering challenges can ultimately be traced back to the fact that there are simply too many people trying to thrive on a limitted amount of resources. Global education of people about science and the consequences of over population seems the most effective method of achieving this goal. If huge amounts of money and diplomatic effort could be spent on the education of the world's population about basic biology, chemistry, ecology, geology, and all aspects of how our planet and its inhabitants funciton, then people would be in a better position to make political and lifestyle decisions.

The greatest problem we face is the ongoing human population explosion. This core problem is a major contributing factor to many other serious problems, such as running out of water, deforestation, desertification, collapse of fishery populations, running out of oil, pollution in many forms, climate change, etc. There are simply too many of us humans for this planet to support. Therefore, the most serious challenge we face, in my opinion, is to find humane ways to regulate, control, and reduce the human population.

Achieving the goal of sustainable development is indeed one of the greatest challenges of the 21st century. If industrialization and economic development is not based on the premise of sustainable development that is in harmony with nature’s carrying capacity (supportive and assimilative capacity), human civilization cannot realize the goal of eradicating poverty and improving the living standards of the majority of its population. The present open ended economy which is driven by unsustainable pattern of consumtion must be replaced with ecological economy wherein the use of natural resources must not exceed the rate of their regeneration. Ecological economy would help to preserve the ecological integrity of the earth system and produce waste only at the rate at which it could be assimilated by the nature. All our present and future developmental goals are to be set on the premise of symbiotic relationship between consumer human race and producer natural systems so that dynamic equilibrium is always maintained between them. The very goal of sustainable development offer multitude of great challenges and opportunities for engineers and scientists, those challenges may be broadly categorized as follows. Materials Materials we formulate and design must have closed loop, either they should be recyclable or be safely assimilated by nature at the end of their life cycle. Production and Process Engineering Zero waste and zero emission Energy I vote for the combination of wind, solar, tidal and bio-waste energy. Until problem of nuclear waste is solved, or nuclear energy is based on closed loop cycle with zero waste it is not a viable solution for energy problem Engineers must design affordable and viable energy generating systems (wind, solar and bio-waste) which can be installed and maintained by individuals at house-hold level. Water and Sanitation Desalination plants driven by tidal and wind energy Affordable biological wastewater treatment plants which can be installed and maintained by individuals at house-hold level Aero-toilets, can natural air be harnessed for flushing instead of water, a great challenge for engineers. Sanitary engineers and compressed air technologists may have to work together Food and Agriculture Genetically engineered crops which use atmospheric moisture for their growth Can we design plants which make use hydrogen and oxygen available in atmosphere and produce water for themselves Can we design a single crop which can deliver all nutritional requirements? Shelter A simple shelter kit which is affordable by masses, can be bought across the counter and be assembled by individuals. Such shelter kits should fulfill the basic functional requirement such as protection from natural forces and man made hazards, privacy and durability. Health Replacing and/or repairing defective parts of brain If any disease is traced to particular genes, doctors simply should be able to replace the defective gene and cure the patient. Indeed a great challenge to genetic engineers and doctors. Elimination of all known inherited or genetic diseases would be a wonderful gift to humanity. Drugs with zero-side effect Build virtual hospital which works round the clock ( 24x7x365 ) and can reach the masses. A patient from any geographical corner of the world simply should be able to reach this hospital through local machine and interact with doctor. Hardware and software required to measure basic health parameters (like blood pressure, pulse rate, temperature etc.) should be part of the local personal computer. This basic data should be delivered real-time to the virtual hospital. At least regional virtual hospitals which can be connected to all villages in the region would have revolutionary impact on rural health system in developing countries. It is great opportunity and challenge for computer and information technology engineers Transportation Transport sector is the enemy of climate scientists. Again a big challenge and opportunity for all those concerned engineers in this sector. Carbon footprint of a typical car is about 250 grams /km, whereas it is 3 grams/km for walking and cycling, so walking is almost 80 percent more efficient in terms of carbon footprint. Human beings are akin to bio-reactors and produce energy very efficiently. Comparative analysis of IC engines and these bio-reactors make very interesting study. We need to understand in grater detail the principles behind the energy production and energy management system of this organic automobile (human beings), and explore the possibility of adopting them in cars and other automobiles. We climb, jump, jog, swim , think etc., I am sure energy requirement is different for these different activities, energy management system of human beings (even some animals) must be very sophisticated and efficient to manage these multi-tasks. If we include energy as constraint, then all these so called state-of-the-art automobiles, aircrafts, trains, ships and even many more gadgets suddenly looks primitive!!! Transport sector should be powered by air, water and sun; it is indeed a great challenge and a pre-requisite for SUSTAINABLE DEVELOPMENT.

Idea For Personalised Learning. In the information age everything is going to become digital or computerised. reading printed material should not be encouraged. yet there is tremendous use of computer printing as the information is always printed on paper for reading. the reason is habbit & less burdon on eyes. the purpose of digitisation i.e paperless office will never achieved.

One of the important thing in urban infrastructure is mass transit.It reduces the polution cosiderably.The stress on mass transit is always high & it became the most usafe & unpleasent mode of travel. the infrastructure for mass transit should be improved to make it more attractive & enjoyable experience for the commuters. one of the method i would suggest is use of natural force- Gravity for mass transit. A sloping track can be built on the existing rail track like roller coster. the slope will cause the acceleration & speed up the car at the destination the slope will not maintain resulting stopping of the car. the bottom of a car has an air bag whose botton will mach with the slope resulting keeping the commuters of the car in horizaontal position. when the car approaches towards the destination the air bag will release the air resulting to make it horizontal agin near the destination.If the car wish to travel again next station it has to travel a negative slope. for this there should be two approchase eithe a vertical lift or using travelling belt which is moving continuously. the structure required for this arrangement will be high in air cosidering 20 meter high with slope of 1 degree.so for every 1 km there would be requirement of lift station of 20m high. the car used for this type of transport will be similer for roller coster with 4 occupants. this method should be studied in engineering asspect with improvements in design.

A Space Elevator is a mandatory requirement for human advancement. Regarding matters of objective environmental research, simple scientific methodology implies that we should be collecting regular environmental data on non-terrestrial bodies, so that a reliable set of base data can be arrived at for analysing the environmental data of Earth. Humanity must explore our solar system, and especially our near neighbours like the Moon, Venus and Mars. This will not be economically viable, via contemporary rocketry, and the carbon load will be prohibitive. Although in it's first iteration a Space Elevator will be a serious scientific an financial undertaking, following versions will be much more accessible. The first 'proof of concept' of a Space Elevator must be built on the moon, where the one sixth gravity will make it immediately doable with contemporary materials and technology. Valuable experience will be collated and inexpensive access to the lunar surface will be made available. Once built a Space Elevator makes Low Earth Orbit launches trivially inexpensive, and real non-terrestrial scientific research in the grasp of even Post-Graduate students. http://en.wikipedia.org/w iki/Space_elevator

Sustainable living, also called a "full-world" mindset, is necessary as all the accessible places in the world either support life directly or indirectly. A reasonable and balanced approach to fulfiling life's necessities need be determined, established and maintained. I've offered a few ideas to folks for reducing the demands people make on the planet, without much sacrifice. For instance: 1. If all the appropriate roof tops in the USA, and wherever it is affordable , were to be used either for solar power generation, solar water heating or small wind power plants the need for new, large, centralized power generating plants (and the requisite distribution infrastructure) could be vastly reduced. Carbon Dioxide would also be reduced and folks would have the power needed for a modern, efficient-utilization, lifestyle without induced suffering or sacrifice. 2. If large scale electrolysis and fuel cells (possibly on a closed, or near-closed, cycle loop) were placed near water sources, along the routes of power distribution grids, then the fluctuations of solar and wind based electrical power generation might be smoothed out efficiently and effectively. 3. I've proposed to a few organizations that we team up to take on the American X Prize challenge of the 100 mpg auto. I believe that there are reasonable and relatively simple steps to that end that, for reasons that (I hope) have escaped me (because the ones I can imagine are seriously unflattering), have not been sufficiently pursued; if at all. There is much talk, in this election year, of energy independence. I feel that unless people are willing to make tremendous sacrifice that that goal is unattainable. However, sustainable energy utilization is possible with moderation and comparatively small changes in our way of living on planet Earth.

Develop carbon sequestration methods: This one is a dual use strategy, make bio fuel, and sequester CO2. http://www.youtube.com/wa tch?v=8hioZ7C6HLs It is the Vertigro System developed by Valcent fuels that uses certain high oil yield algae to turn sewer waste into bio fuel, and the remaining material can be used as fertilizer or sequestered underground possibly even in dry oil wells. The best part is the land used to grow the Algae can be desert, and thus not disrupt land used to grow food.

I think I'd have voted with the majority to make solar power cheaper but I'm pretty sure this is already happening. REC is putting in a 1.5 GW manufacturing plant in Singapore and this should have the scale needed to make solar power cheaper than coal. The US is falling behind in solar power manufacturing and should try to do something about this but costs are going to go down dramatically if we do or if we don't. So, I voted for sequestration. But, I don't support sequestration of carbon dioxide. I think we need much better engineering than that. We need to sequester carbon in elemental form or as carbonate minerals. And, we need to do it from the atmosphere, not power plants. This, I think, is going to be the greatest engineering challenge of the next fifty years. We need to bring the concentation of carbon dioxide in the atmosphere down below 320 ppm from its current value of 385 ppm. So, we need to retrieve about half of the carbon we have put into the atmosphere since about 1965. The biosphere has soaked up the other half already. Revisioning engineering to be planetary and cooperative with the ecosystem seems to me to be about the only way a challenge of this magnitude can be met. Managing the nitrogen cycle is probably only an beginning for this.

Submit that until corruption of our rulers and barriers against social reality is dealt with, any further technological progress just adds weapons to the arsenals of tyrants and further enslaves people who must react. I am no Luddite, I am an engineer and innovator. The way engineers can help is by fighting the forces of ignorance and manipulation. The "rule of law" is a precisely defined law. It is the highest law of mankind, stated below: the suppression of forceful and fraudulent methods of goal seeking all are treated equally by the law. This means ALL, including king and judges absolute property rights This in turn is based on the fact that human behavior (the topic of law) is about goal seeking. In the seeking of any goal, there are only three possible methods: force, fraud and honest trade. Any transaction that is not an honest, mutually agreed trade will cause a self-defensive response (conflict) from the victim whose survival has been affected. "The Rule of Law" is the glue that keeps all of mankind acting together in common interest, tied together by mutual dependence of trade, on an evolutionary path to excellence. Force and fraud creates conflict and destroys civilizations. Mankind is now on a devolutionary path to extinction because the co-operation once forced by "the rule of law" has been replaced by legitimizing force and fraud for those who incorrectly believe they wield power.

The biggest challenge and first priority must be towards de creation of one or more solutions for clean and cheap energy. After solving this problem, Humanity will have the means to reduce other problems of the society like pollution, waste management and access to cleaner water. Logic would suggest that the sun, wind and tides should be the correct sources to use for energy harnessing. In parallel with that, investment should be made in order to abandon the centralized production of electricity, since it's transport over long distances is so inefficient. The generalized use of solar panels and wind generators in buildings should be promoted so that electricity could be produced near the consumer, thus avoiding waste in it's transportation. This would also allow for the usage of lower voltages avoiding health problems associated with very high voltages (leuchemia and others).

I do indeed have an idea, more than one in fact, but first things first. Hydrogen power seems to be the way we are turning these days and I for one like the notion. I know the problem is a power source to actually make hydrogen resulting in possibly more consumption of resources. I say what is the feasability of a small plant that is owned by the power company (so they won't be left out of the loop and still make money) that hooks up to the water that already comes into the house, and is powered while you are away by both a small wind turbine and solar cells? Surely this can account for enough to store and use for most of our population. ( I'm just talking vehicles for now here. ) When it comes to bigger buildings or other business why not simply use the same idea to a larger degree? Based on traffic, a scale could be used to determine how much they should generate for the community, or of course, themselves. Things don't happen unless people see profit of some sort in the venture, be it either of a material or a moral/spiritual nature. This solution could provide a lot in both directions without taking away anything from anyone. Start up costs would be a lot, but they always are. I know the idea of a hydrogen generator on every structure soulds like overkill, but I feel it is more practical than central stations doing the same thing since wind and sunlight hit everywhere eventually. The only downside might be in drought stricken areas where water needs to be squandered. Solution- recycling the grey water generated from the house or business. Once it's processed leftover sewage simply gets washed down the drain with enough fluid to make it flow.

I am most interested in using incredible economies of scale to boost access to global communications and information infrastructures for both developing countries and underdeveloped populations in more advanced economies. For example, the concept of utility computing, where the applications and information you required for any purpose would be readily available over a global network (aka the "Internet"), is changing the mindset of a generation of technologists about where and how computing should take place. If you reduce the need of the global citizenry to own electronic infrastructure--through public access points, super cheap wireless smart phones, etc--then computing becomes increasingly ubiquitous, which in turn increases the economic power of successive generations. Of course, all of this computing requires power, so I voted for solar power as the most important engineering challenge.

Ironically, the safest and most abundant source of continuous, carbon-free, renewable power on Earth is right under our feet in the the heat of the crust of the Earth itself. And the technology to access it is called Hot Dry Rock (HDR) Enhanced Geothermal Systems (EGS). I call it Earth Power. And you and I already invested $100 million of our taxes dollars over 24 years in the R&D at Los Alamos National Laboratory to prove that it works! So why not use it now to solve our major problem? It's time to scale-up this brilliant long-term solution to our fundamental energy insecurity and invest in a PERMANENT Earth Power utility system that benefits everyone. Because --- buried in the Jan '07 MIT (DOE-funded) report, "the Future of Geothermal Energy", drafted by world experts in geothermal development, is the astounding estimate that, using existing technology, in the Earth's crust just in the Western US is enough accessible, convertible heat to produce SEVERAL THOUSAND TIMES all the electricity generated in the US in 2006 for SEVERAL THOUSAND YEARS! That's more than 1,000,000 years of safe, carbon-free power! Not peak oil that will end in this century. Not coal that we've still got 100-200 years to choke on! Not nuclear power with meltdown and waste problems for millions of years. Several million years of reliable, clean power -- without destroying ourselves or the world ecosystem! And Earth Power's accessability is spread over huge regions of the Earth that can be accessed almost anywhere with a tiny foot print (avoiding obvious fault lines) allowing universal decentralization for maximum energy security and optimal economic equity. And this astounding estimate only assumes the use of EXISTING technology. The HDR/EGS power-generation aspect is relatively simple and low cost. The big upfront capital cost is in drilling miles into the crust (ironically using advanced oil-drilling technology) to create the artifcial geothermal fields that generate the steam that power the turbines to produce the power. The Western US has lots of hot dry rock areas that are closer to the surface and easier to get to. That's why the experts focus on developing it first. We need the power and we've already publically paid for the technology to generate it for eons. So let's use it. Here's the really Grand Engineering Challenge for the 21st century: having the wisdom to realize the Grand Energy Opportunity of the ages. And just like the US Interstate Highway System, the apparently daunting upfront costs very soon will be dwarfed by the far greater benefits of the newly installed super-system. Our recent technological history clearly tells us that the positive R&D re-investment 'snowball effect' quickly lowers the cost of new capacity expansion. Focused, competitive R&D multiplies technical breakthroughs that lower costs and increase efficiencies, often suddenly and dramatically. It's happened before with the Silicon Revolution and it will happen with Earth Power. And consider that unlike all other renewables, such as wind and solar, Earth Power runs continuously 24/7/365 for literally eons! These artificially created geothermal fields do have their operating life, but these are proportional design and economies of scale issues, not fundamental obstacles to making it work, not only here but everywhere on Earth. Think of the large upfront investment it would take to set it up as a million-year mortgage on PERMANENT human civilization. Whatever you're paying on this initally enormous million-year mortgage, its obviously going to be an immensely positive trade-off to maintain the mortgage while we devoted thousands of years to our social and ecological as well as our technological and economic development. Because with Earth Power, we now will have secure, continuous, safe power getting cheaper and cheaper, which will help fundamentally and permanently solve a vast web of related problems (urban design, desalination, electric transport, distorted power politics, the economic roots of war, global development injustice, allowing the smarter use of limited fossil fuels for higher value-added purposes, etc.) And one of the experts who actually demonstrated Earth Power at Los Alamos tells me that after you pay for the set-up costs, the cost of the power drops 80-90% to less that $0.01 per kWh! Earthy Power is perhaps THE single best alternative for solving the post-oil global base load problem (running power day and night all year round without having to store it). It can effectively replace coal and nuclear - without their pollution and political risks. Again, with the base load covered the coal can be used for essential hydrocarbon products, not wasted by being burned for crude heat! It's like burning the library to stay warm while you try to read by the fading fire light! However, the most astounding thing about the MIT study besides its estimated mind-boggling upside, was the utterly myopic, timid proposals made by these paid experts to further investigate and develop Earth Power - surely disappointing considering its obvious, enormous potential advantages and our urgent need for them! I guess experts have to be careful not to upset the bureaucracy, jeopardizing their next research grant with unbridle optimism, even if its objectively warranted. But I don't have to be timid. Neither do you or the rest of the American taxpayers who've already paid for this breakthrough. This is the time for bold wisdom, grounded in practical reality, not timid caution. Earth Power deserves courageous leadership with the vision and political power to make this an essential part of a foundation of permanent solutions -- while we still have the resources and imagination to make them a reality. As an earthling, a US citizen, and a concerned grandfather, I got excited enough about Earth Power to immediately contact two of the key people who did the research at Los Alamos on my own and I went down there to meet them. Don Brown is a retired nuclear engineer who is the inventor of some of the primary patents on HDR and Dave Duchane was the former project manager for the Los Alamos HDR project for many years. These two smart, dedicated gentlemen graciously hosted me, and took their valuable time to explain the history and prospects for Earth Power to a complete stranger with no qualification. I was amazed by what they showed me. Don very kindly took me out to the Fenton Hill site up in the mountains near Los Alamos where they drilled and ran the first HDR EGS power system in the 1980's and 1990's. It's still there, with a small weed-covered plaque com-memorating the place where human beings created artificial, clean geothermal power for the first time in history. I was deeply moved, thinking that this modest spot might some day be considered more important in human history than the blasted, desolate Trinity Site where the first atomic bomb was detonated. This little pipe end in a beautiful mountain meadow was where human beings discovered how to permanently assess the safe, clean, non-military power of the natural heat of the Earth on which they finally established a permanent, sustainable human civilization that would be compatible with the survival of ALL life on Earth. These two retired pioneers and the network of other top people who worked there are a collective national treasure that needs to be recognized and honored by being listened to, by being supported to pass on their vital knowledge to future generations, so that we can make full use of the amazing breakthrough they demonstrated. Only a handful of projects demonstrating the commercial scale of Earth Power are underway in Europe and Australia. Just recently, a new venture, called Altarock, backed by the visionary venture capitalist, Vinod Khosla, is starting to build the first commercial Earth Power systems in the United States, using some of the technological innovations of pioneers like Don Brown. But its still a relatively modest start - compared to the gigantic potential of Earth Power. We need hundreds of these ventures, now. And Don Brown rightly points out that the most important place to start yesterday is in China, to prevent the eco-catastrophe of coal there from eventually choking our children into our living rooms. I am trying to help him do this, but it is well beyond my limited contacts and talents. We share a common threat and an open oppotunity to do something about now. I encourage anyone seriously interested with access to the resources to help make Earth Power happen to directly contact Don Brown  and/or Dave Duchane. These two, delightful, intelligent guys just want their life's work to be used for the good of all earthlings. I trust that we will eventually show ourselves to be wise enough to do this. It may be part of the ultimate Darwinian test of whether or not human beings are fit to continue to be earthlings. Somehow, I know that we WILL build a permanent eco-healthy human civilization, based - in part at least - on Earth Power. After all, we've taken millions of years to evolve brains capable of eventually understanding that we are standing on the answer to our greatest problem. Maybe Louis Armstrong will be proven right after all, and future generations will sing our praises with him: "what a wonderful , wonderful world it will be!"

Soon every home could own a home printer that will produce any plastic utensil or toy you can think of. Not to long after that fully functioning plastic and electronic devices will be printed. Ultimately the cost of innovation and building of ideas may become much easier and cheaper once 3D printers bring down costs of prototypes to the level of mass production.

Manned space exploration is essential to the continued survival of the human race, and part of a program to leave our planetary cradle should be the creation of a relatively inexpensive means of achieving Earth orbit. All, or at least the large majority of, national and international space program activity should immediately be focused on the goal of sustainably settling outer space, the moon, and other planets. The geologic record is replete with instances of massive comet and/or meteoric impacts, some of which affected the entire planet. Supervolcanoes, which we can do nothing about, have erupted repeatedly in the past, wiping out massive numbers of species. We know from DNA records that the human race was significantly reduced in numbers around 70,000 years ago. We know from ice core drillings that world-wide, major climate changes can take place during the course of a single human life-span. As we build space habitats and planet or moon based habitats, our experience and knowledge on how to build such habitats will grow until they are eventually able to become self-supporting by extracting raw materials from the asteroids or the satellite/planet they are based on. Keeping our heads in the sand by thinking that it is impossible for a major, human-race-extinction-cau sing event or events to occur while we inhabit just this one planet is the height of foolishness.

One innovation that seems quite neglected, despite being, I think, within a decade or so from commercial use, is use of "smart vehicles" to increase the capacity of highways without additional lane expansion. Here in the rapidly growing Research Triangle of North Carolina, there is much talk of new toll roads and intercity light rail systems. It could easily take more than 10 years, and billions of dollars to add these investments. In the same time frame, we could probably develop cars and buses that (for starters) could go into dedicated lanes on existing highways, be put under auto pilot while in the lane, then speed along at a constant speed with much less space between vehicles than on current roads. The constant speed alone would save fuel, and the increased number of vehicles per lane would increase capacity. At the end of the high speed lane, control would be returned to the driver. I would think that drivers might be willing to bear the cost of the in-vehicle equipment, just as they are starting to do with more primitive accident avoidance and self parking equipment.

"...how to create connections between man and machine, neurons and transistors." 

Of all of these "Grand Challenges" I believe the most critical one, and therefore the one that should be addressed first in a massive Manhattan Project type of assault is reverse-engineer the brain. The potential applications described in the write up on this challenge described just the tip of the iceberg of what will be the most powerful benefits of this technology. Curing neurological disease will certainly help many of thousands of people, but the benefit that will effect every soul on Earth will be the knowledge of how to create connections between man and machine, neurons and transistors. An example of this would be a question that originates in the mind of a scientist, this thought radiates throughout his brain crosses over to a microprocessor which in turn searches the whole human knowledge via the internet and when the answer is located it is returned directly to the brain of of the scientist all in the blink of an eye. No monitor, no keyboard, no mouse, no operating system, just thought and result. Notes, databases, calculators, other minds all available just a thought away. This would mean never forgetting anything, organization, and intense productivity. This technology will push the development of everything allowing these other challenges to addressed and resolved in fraction of the time.

We are a world who wants to be healthy but may never find the time or motivation to put ourselves to work when becoming physically fit. Maybe the money is an issue because health clubs are becoming increasingly expensive to use. My idea is building health clubs everywhere in a city or town with equipment that produces power through people. Like those giant wind farms you see in fields out in the middle of nowhere that produce power though wind moving a turbine; Bikes and ellipticals by hundreds or thousands could produce energy in the same way by people getting their daily workout. Maybe it's not just bikes and ellipticals but some other weird contraption that would bring many people together to produce power through exercise.

There is an extremely ambitious "mega" project, just beginning to go public (after numerous years of working discretely), which, for the most part, has already come up with solutions to all 14 challenges, and a whole lot more. . . A clean-slate solution for reinventing civilization, fully integrating advanced new SUSTAINABLE systems for transportation, food production, housing, communications, health care, entertainment, etc. - designed as a complete end-to-end system for maximum efficiency and minimal cost. A solution involving HUNDREDS of (never before revealed) innovations, breakthroughs and inventions, which results in a brand new POST-SCARCITY society. A solution that is apparently capable of bringing EXTREME PROSPERITY, not to a lucky 5% of the population, but to everyone on the planet - in a fully SUSTAINABLE way, free of exploitation, but rich in advanced techology, automation, efficiency and clever design. The key is setting the right goal ("creating abundant prosperity and opportunity for everyone, without harming anything" as opposed to "lets make a quick buck"). It is quite exciting to contemplate the possibilities of a future that bright. Actually creating it is the next step. . . Check out LoveTopia.org for the beginnings...

Evolution of intelligent life is our primary goal; reverse engineering the mind is the most important, although not immediate goal. It is the key for technological acceleration and human evolution. The immediate goal is cheap energy, because without energy work cannot be done, and humanity will quickly engage in worldwide no quarters warfare. Solar, Fusion, and Solar Power Satellites, are the Holy Grail for energy technology, and are needed to expand and sustain world economies. Humanity's evolution with Brain Machine Interfaces, Artificial General Intelligences and Gene sequencing will survive almost any possible future scenario, including a likely post nuclear apocalypse. If achieved, our second manifest destiny will be assured.

There seems to be an interesting omission in this great line-up of challenge: Create software engineering tools that allow the collaborative modelling of complex realities such as the human body from the molecular level on upward, the history of the universe from the Big Bang onward (or even before), the detailed cultural history of the middle east, the planetary climate or thousands of complex situations like these. Without the reconstruction of such realitiesw we will not be able to solve the biggest problems facing this planet, because onl this way these complex realities become comprehensible as well as the subjects of human experience and therefore interaction.

A fundamental underlying issue here is that most of humanity does not comprehend engineering and science itself. People worldwide take for granted what only a very talented few (smarter than me) have developed. The engineering community is the only community capable of solving these technological challenges. Most non-engineers don't actually know how the wings of an airplane develop lift, or how cell phones transmit calls. They don't understand how fusion works, or how solar energy can be converted to electricity. They are great at leveraging these technologies once they exist, but most can't see their way to the solutions beforehand. Thus our collective human shortsightedness keeps us from directing adequate resources to solving outstanding issues. The problem as I see it is not to rank these very solvable challenges, but to obtain funding and staffing to complete all of them. Then, once the solutions are developed, to motivate countries around the world to deploy them. That makes this, in many ways, more a challenge of leadership than of engineering. Luckily we at least know that the engineering portion can be done.

Well this could be a book. This grid scientist who consistently insists we are listened to so that engineers can task in the proper direction and not be led down the path to enhance the boys with your purse strings attached. Engineering a proper train system in the USA will be where we eventually go. My design for that new system after being tasked to do just that has been held up by very powerful interests,but they can only hold us back for just so long. The ned to reduce the amount of carbon in the atmosphere and reduce the use of all of our resources at once and plan for the future has many proponents,and hopefully many,many more when we install our plan. The highways are beat to death by heavy truck traffic and the repairs keep the system drained of resources. The trucks in my system run down the rails to the closest siding(With many sub-sidings also built) The semi trailers are modified to be a spread axle setup with train wheels ahead of the front and rear rubber tires with an air deployed system. A dolly with train wheels is attached to the king pin and at least 10 trailers can be pulled by one modified tractor,(All weather) up and down the routes to drop and pick trailers for local trucks and switchers to place at their destination. The main north/south-east west long routes could have 50 or more trailers pulled down them to be put on the short lines along the way or taken full route. Trucking companies contract wit the system trains to task their trailers to the point closest to their final destination.and so are still in business,their revenue will not drop,but their expenses and liability will and the roads last 10 years longer and we use 50 percent less fuel.We have much less accidents and weather and driver problems. There is also a completely designed passenger system that takes no additional right of way that I have designed to co exist with the freight system also,but is far more than the brief I just released. But it completely relieves the congestion in all cities. There is also alot more that my committe has on its shelves to enhance all of the major problems we have on this planet. We are earth scientists,we are grid scientists,we are also engineers when need to be.Our group designed the earths and the universe long ago and has responsibility for our grid system today. We are an organization called "Earth Service" Usually very private,but find the need to task public until repairs are made to earths systems.

Energy - Please don't limit this challenge to solar or fusion. Just state the challenge as energy independence. Examples A. one orphan concept are exothermic hygroscopic materials which can store thermal energy indefinitely and most certainly between for the period between summer and winter. Such materials can release heat hot enough to cook on. Energy density is good (visualize 3 or 4 250 gal oil tank sized units to cover your upper eastern USA 2000 sq ft home). This technology would require roof top solar panels to harvest the summer’s heat. No technical hurdles, just basic mass-produciton related issues. B. metal hydride hydrogen storage coupled with desert solar. Charged tanks would be shipped to those that need the power (think of propane tanks). C. re-chargeable hybrids – come on Detroit, we are the verge of this, I can taste it. Make us a car that can go at least 1.25 hour on a charge. Tell big oil to stop secretly thwarting this and be good patriots and get behind it (put your billions into electrical generating plants – don’t die, adapt) Education – Needs a big overhaul, way beyond internet instruction. For example, make the alumni association like software maintenance – you sign up and your school sends you scholarly updates including software. Increase cross fertilizations – The math department needs to share the wealth. It is like the Marines and Navy and army all having their own airplanes. Stop all lectures that are memory exercises, analytical thinking from art to architecture! Insurance (yes insurance too boring for you?) – Here’s a simple idea – share accident location data with all insurance companies. If a certain intersection routinely has accidents of over X per unit time (which cost insurance companies big bucks), then the insurance companies could pay for a traffic light and get a rapid pay back. The Ins. Cos. win, the towns win, the people win. After all, the statistic that 30,000 die per year in car accidents is a massive outrage, makes Iraq look like small potatoes and we are doing this to ourselves! Health – Repeat after me – Poor people end up on the doorsteps of emergency rooms with horrendous problems that could have been stopped weeks earlier by small practical measures, lets get basic coverage to every one, don’t get all balled up over if this is going to be a government or private solution, lets come together on this one. Let’s also elevate fees for participation in dangerous stuff. Yes Johnny can pay football, but society might have to deal with his brain injuries for decades, repair his blown out knee, etc. We need to go from a system that is poised to handle all of the dumb things citizens do, to a pre-insurance system where participants pay much stiffer insurance fees up front to advertise the risk they are taking (and no more free rescues of bumbling outdoorsmen off of public mountains, oceans, etc – make them pay full freight for their rescues). Doctors have massive statistics on risk (how many toys kids choke on, how many ski injuries, etc) – public must be better warned (like cigarette labels).

Only one challenge - IDEA'S then Only two objectives TIME and ENERGY. IDEAS - Generating ideas - At Will - can transform everything now. Humans can leap forward as far as you like, as fast as you like, just by designing the basis of idea generation. We already know the answer - ANALOGY. Ideas are generated to meet any challenge by analogy. But we don't know the mechanism and have been stuck with the brain, a fine parallel processor with a hopeless 8 bit serial input and output and don't share in neuron real time. The objective of Ideas is to extend Time for humans until its unlimited and to provide Energy until its unlimited. Everything else is free. With time and energy you have everything. There are no resource limits whatsoever in the environment. With energy I can make anything, travel anywhere, do anything. Setting any target other than idea generation mechanisms, shows the problem is not appreciated. People are stuck in the technology era. Grand challenges are neither grand or the right challenge. Humans cannot fix them in the time available. Designing Idea generation is not difficult, but does require one final and last co-ordination effort for humans. It will happen anyway and soon but not as fast as needed or possible, especially while the best people are working on TACTICAL stuff like the challenges. "Design the the Designer" not the stuff.

The concept in the formation of engineeringchallenges.org is superb. BTW, I voted for "Solar Energy". The world has long been wanting for the guidance of an international panel of experts on civilization. Notice I said civilization and did not say engineering. Civilizationchallenges .org would have been more to the point. That point being that all governmental systems yet tried by mankind have proven themselves to be unarguably inadequate to respond appropriately to the challenges people face. In the past, the consequence of this inadequacy was simply more human suffering. Now however, the fate the earth hangs in the balance. I do understand that a declaration on your home page that "All governments have proven themselves to be incompetent." is probably not a wise course of action. Nevertheless that does not preclude you from, in fact it is your responsibility as members of an international panel of experts to benefit mankind to, list as one of the chosen pressing challenges "Research into the development of more effective political/economic systems". Surely this can replace "Advancements in Virtual Reality". ?? OK, I've come this far. Here goes. I've often thought that I would like to have James Burke, the creator of the "Connections" series, drafted to be Czar of the planet Earth. He would never do it willingly. He would have to be forced. OK, so we can't achieve that (yet). Here's a rough outline for a political system of government to be recommended as a replacement system of government for all sovereign states. All members of the advanced Academic Community (read professors) vote upon who is the most outstanding leader of their field of expertise. The "winners" are obligated by law to agree to convene a "Convention" at which they will nominate and vote upon a candidates to be the "Chosen Leader" of the sovereign state. The person who is chosen may not refuse to serve, under penalty of life imprisonment. The "Chosen Leader" will have a term of office of 15 years. All of his/her decrees will have the full force of law. The "Chosen Leader" may at anytime be impeached by a 60% vote of the general populace. There will be daily impeachment plebiscites held on the internet. The convention of Academics is responsible for setting up the administration of these plebiscites. The only preclusion to the power of the "Chosen Leader" is any alteration to the established administration of the Impeachment Plebiscites. At the end of the term of office for the "Chosen Leader" or in the event of impeachment, the entire process begins again from scratch.

Without a doubt, the biggest issue of our time is the issue of clean and efficient energy production. All other aspects of modern life, both the problems- clean water, global warming, poverty- and other concerns, e.g., space travel, economy, and social issues are recognized because basic human needs are met, in much of the world, with the production of energy for electricity. However, in order to continue and increase the prosperity of all people, more complete sources of energy are needed. I was very happy to see nuclear fusion included on this list, as it is most certainly the most complete source of energy that will, hopefully, be availabe in the not-too-distant future. Although I support renewable energy, no form of that energy is available that can compete with either type of nuclear energy, whether fission or fusion.

As others have alluded to here, I believe that the challenge lies not in finding any particular engineering solution but in creating systems of government and commerce that do not, of necessity, drive unsustainable practices. Since China and Russia have embraced forms of market economy it is universal amongst the world's large economies that people's everyday needs of food, clothing, housing and, to a lesser extent, education and healthcare are all met via a system that demands constant economic growth in order to function. This is also true in the macro economic world that, through the funding of business, research and even aid and defence budgets ultimately decides which of the engineering challenges you posit will be met. Until we can create a system that does not require constant growth to meet our needs for wealth distribution then our battles against pollution, overpopulation, and the overuse of scarce resources can never be won.

Carbon sequestration also occurs in living things. Trees are towers of sequestered carbon. Sequestered carbon also is measured in board feet that, used as a building material and covered with paint or varnish, can prevent the release of its cargo of carbon indefinitely. Switch grass, kudzu, honeysuckle, hydrilla, henbit and nutgrass are also perennial reservoirs of carbon sequestration that also increase atmospheric oxygenation. If we were making ethanol/ methanol from these and other undesirable but prolific flora, instead of food crops that require fertilization, perhaps our reliance on fossil fuel could be mitigated. Our foudries, factories and fossil fuel power plants emit tons of CO2. Would it be possible to deliver this as gas to area cropland where it could be slowly released to fuel photosynthesis during the growing season? Alternatively, could not the factory be surrounded by greenhouses growing crops to sequester the carbon and in turn provide feedstock for the factory boiler or the ethanol/ methanol industry? The common practices of clearing woodland by slash and burn, by burning off managed forest and grassland, and by bulldozing massive piles of trees and brush for burning all increase CO2 emission. Could not portable power mills be placed on site to process undesirable vegetation, either into electricity or into fuel? Could not any CO2 produced in the process be captured and transferred to cropland? Could not the woody vegetation be processed in a chip mill to produce waferboard or OSB, common building materials? As your discussion of the historic carbon balance noted, the carbonate was a repository for excess carbon. So, too was Pennsylvanian and Missisippean vegetation, coal mined today to produce electricity for our people. That carbon was sequestered in massive quantities for millions of years. The process continues today in our forests and fields.

You list a group of specific items, such as "solar energy" or "fusion", yet, there is a major SYSTEMS ENGINEERING problem of identifying what is the best environmental, scientific and economic path forward. Solar energy and fusion may just be a small part. Urban sustainability, localization, improved energy transmission and improved energy production, across the board, could all be players. For example, biofuels, which were so highly touted by our country as the solution (primarily so that folks could get wealthy from ethanol) has been discounted as maybe causing more harm than good.

Communities of practice will become localized accrediting mechanisms that assign "title" to knowledge assets. People have ownership of their knowledge - and behave as entrepreneurs. 3. A percentile Search engine will predict the probability that various combinations of knowledge assets can execute a business objective. If it can be predicted, then it can be financed and insured. Innovation risk approaches zero. 4. Innovation risk can be diversified away and innovation cash flows can be predicted. As such they can be amalgamated into large cash flows then divided into innovation bonds. 5. Innovation Bonds can be sold to public at competitive market rates - everyone becomes a venture capitalist. 6. Innovation equals the rate of change of knowledge with respect to time. Knowledge equals the rate of change of information with respect to time. 7. Wall street quants can invent derivatives representing proxies of innovation, knowledge, and information flows which correspond to predictable cash flows. 8. Global technological priorities will naturally reallocate by fair market forces to those projects that have the highest impact on long term human productivity. 9. All NAE projects noted in this website are simultaneously funded by trillions of dollars of cash simply looking for the highest return and lowest risk. 9. The rest is history.

Hello. I think you should include the following as one of your main areas of research: There is a real possibility that global warming will not be stopped, and that one of the outcomes will be a significant rise in sea level. This, in turn, will cause hundreds of millions of people to be displaced and cause immense damage. Engineering needs to develop an international project to deal with this. (Methods of storing food, medicines, and materials; how to relocate people in a controllable way, etc.). In addition to sea level rise, there may be long-term changes in the climate that will change rainfall patterns, making vast areas of farmland into dust bowls. Engineering should address issues of how to divert and store large quantities of water for irrigation and public use.

An excellent and worthwhile program. I consider competitive solar power as one of the prime objectives for a better world, but this should also include other alternative energy sources in areas that do not have abundant sunshine, i.e. Scandinavia, Russia etc. With cheaper, and more abundant power, this will also immensely help with the clean water initiative, less political strife, and an overall improvement in the human condition. As part of your program, I would also recommend updates on what average people can contribute to the process, whether political 'pressure', general ideas or support, or as a tracking median on progress. As a full time RV'er with over 30 years experience in the international arena, there are many early retirees and others that would be more than willing to participate if information is available on how.

Advancing personalized learning is imperative to say the least if we as an intelligent society are to claim a roll in survival. Do's & don'ts in accordance of what's right and wrong today is based on popularity and tradition thus putting the blame for the destruction of life in a Pandora's box which when opened for discussion brings out more destruction through what's more popular by way of another standard tradition! Advancing personalized learning should equal the understanding of words that promote all life without exception. All things rather good or evil are made of words which were truly discovered by the electron microscope and that lesson wasn't learned due to the personalized advancements of selfish goals which destroyed many other words of life that makes up the life the science world now sees as a threat as an over industrialization of toxins. Where do we go from here? The debate has been open from the beginning of time and humans seem to be putting an end to it P.S. The positive energy of words that balances the right to live obviously is being used for self goals there- by for the magnetic properties that holds it all together is vanishing. My studies has gone way beyond the Advanced personalized learning of the science world of earth if that should make any difference to the group that seeks recognition. Good luck with this idea! If you want help let me know... David Loomis

We have the technology and the intelligence to transition into a world in harmony with nature. I believe the biggest challenge will be with getting people to change. People in general seem to have an aversion to change and also a sense of invulnerability or denial that bad things will happen to them until it's too late. Personally, I have made all the changes I can without the means to go further. I try to convince others to even make small changes in their own lives. The ones I cannot convince that way, I try to show the potential profitability of investing in alternative energy stocks. This way, everyone does some small part to initiate our transition into the future.

"Cheap electricity, water, and keeping pollution at bay are my main concerns. " 

The challenges addressed here are of vast importance. I personally feel that the most important tasks ahead of us are those that involve the environment. Cheap electricity, water, and keeping pollution at bay are my main concerns. Considering myself as one who's moderately knowledgable to knowledgable about technology and global environmental problems, I believe it's in our best interest not only to come together to find the best solutions to our great problems but to communicate to the general public the problems and possible solutions. If anyone has noticed the same trend that I have, it's that people simply don't know or don't understand the problems the world faces today. At the top of the list of the engineers challenges should absolutely be to find a way to communicate the severity and need for quick actions when it comes to the most pressing problems. Without the majority of the public actively participating in the solution, there's a greater chance that the proposed solutions either won't work, or they'll be heavily delayed. What the world needs before it's problems are solved, is to inform the "average Joe" why and when, before the how.
