Is this like the nuclear battery chip which we are told can charge your cell phone for the next thousand years? Only problem is it takes over 2 years to produce enough electricity to charge the cell phone. Dave has a great video on it,
The first computers weighed tons and filled a building now I have a smart phone with millions of times more computing power which also allows global communications. I have a good feeling about this technology and all the biggest breakthroughs are coming from nanotechnology related energy systems.
This concept is basically Maxwell's Demon, harnessing thermal motion on the atomic level to produce electricity, Maxwell would be proud of how far we have come in my opinion.
