PV Gap

Cathy Said:

What do they expect solar cell efficiency to increase to and what impact would this have on the use of solar?

We Answered:

There is more than one type of solar technology and it is getting more efficient all the time. All I know for sure is my PV system generates more energy than I was quoted and I will break even in about 6 years so I'll have about 18 years of free energy which will save me well over $50K. That's efficient enough for me.

Use of Nanotechnology in Solar Cells and Hydrogen Cells?

We Answered:

It is predicted that nanotechnology (NT) will bring revolutionary changes in many areas, with the potential for both great benefits and great risks. Developments in the military could entail specific dangers, containment of which will need special analysis and effort. Military research and development in NT is expanding rapidly. Potential future applications span all areas of warfare. Special dangers to arms control and stability may arise from new biological weapons and microrobots. For humans and society, non-medical body implants – possibly made more acceptable via the military – raise a number of problems concerning human nature. Further research is needed to find the best way to avoid possible dangers. For the near and medium term, several guidelines for limits and restrictions are suggested. As a first step, transparency and international cooperation should be improved.

Ways to use chemistry, biochemistry, or nanotechnology to address green sustainability.?

We Answered:

fool, none of that works, all of that need rare metal that produce more green house gas and take more enegry then you get out.
