Interesting story. I do not believe it is far fetched. Some time in the future...maybe 20-100 years from now, this may be a type of product picked up for a few hundred of todays dollars and be smaller. With the advancement of nano-technology I would guess we can produce things like this when we begin to understand how to truly manipulate molecules en-mass. I would love a product like this on my 10 acres as I could have something to power the home and there would be no blackouts when the icestorms came......If there is a portable one, it would make camping a riot! Keep one in your car to use at the beach....good stuff.
I agree completely. I think nanostructured materials will give us huge breakthroughs in many areas of technology. It appears that one such has just been made for solar cell efficiency:
