Took a few minutes to peruse the Powerchips site.
Very interesting to say the least.
Depending on the efficiency, those could potentially rival photovoltaics in a solar reflector setup.
Going to keep watching that site to see if it pans out.
I'm on the borelius mailing list, get regular updates. They are actually a metals/mining company. This is a sideline to them. They are also doing this wheel tug thing for big jets wherein the jet can move around the airport tarmac on its own w/o ground tugs.
I first heard about this powerchips thing in Infinite Energy Magazine, Eugene Mallove editor. Eugene was murdered in may of 2003 by some druggies. It was really a super magazine then on new energy concepts but has since gone downhill. See infinite_energy.com; the back issues pre-2003 have some real WOW stuff.
