What Do You Think?

The 14 NAE Grand Challenges for Engineering can help us to target our research direction and try to solve those problems that affact our life most.

I think this website is very good and had potential.

I like to take this challeng to study more about the engineer tools

All of the above grand challenges are fairly high-tech in nature with one exception. This is the one concerned with providing access to clean on water. Since the basic principles of water treatment already exist, I would imagine that this p[articular challenge might take on forms such as appropriate adaptation of technologies to suit small scale water treatment applications for example for rural areas and villages. I would imagine that the emphasis in innovation might be in cost effective adaptations as there often will be little funds available in the regions concerned. Any advanced technologies (e.g. nano-filtration) might e.g. more applicable to areas where clean drinking water already exists and not to those that lack basic potable water.

Hence, this particular challenge may well lie squarely within the appropriate technology. I am a chemical engineer. I have been looking at appropriate technologies in the area of water treatment. I must say that even these do exist as there are companies that have containerised small water treatment plants. The challenge may be to produce a super low cost water treatment plant that can be run by a village.

I would like to follow this up further. I am pleased that there is at least one relatively low-tech grand challenge on the list.

A grand challenge will be to protect our oceans by cleaning up the microplastics in the gyres, and reversing acidiification.

We are now in the age of computers and the truth is easily exposed using basic mathematics and physics and the power of computers to do the numerical calculations required in the equations that we derived for a particular problem.
Microsoft Excel can be applied by the computer to perform any numerical calculations required in the equations derived mentioned above. Approximate methods may not be correct anymore once the exact method is applied.
The whole world is still using the approximate method exemplified in technical books and favored by authors and college professors who had been brainwashed and buried using existing literature even though computers are all over the place.
I am the only one in the world doing the ‘rotation of axes’ while everyone is copying the ‘principal axes’ in any given rectangular and circular section. I have shown the way in all my presentations and technical books on the analytical method in structural analysis.
It is obvious that a new paradigm from the approximate to the exact method is called for everybody to discover the truth about anything using basic mathematics and physics learned in school. A serious researcher should follow the saying ‘seek ye the truth and the truth shall make you free’. Tons of literature based on approximate methods should now be discarded in favor of the discoveries which can be made by this new paradigm.

We have to build a thought for future challenges..Is it possible build a ship traveling under the sea?????????????Think like MECHANICAL Engineer..........

I was fascinated by the solar/wind car developed by an engineering student of Shivaji University Kolhapur. Can someone give more info ? I want to post the news.

Virtual reality already exists and is very advanced.

about making the most economical solar energy I think it would be one of the biggest challenges for engineering and there are many of General Interest. I think we would have to focus on people and how you think about this, change the culture and show the future benefits .In my city this would be very beneficial because we paid big money for the electric power and is one of the hottest places in the planet so it's a necessity have air conditioning. I wonder if anyone knows how we could make this possible? or how we can sensitize the people about this topic?
