Thoughts? Wow! I had no idea this would generate any replies at all- just thought it might be worth a moment of incredulity to some of you on its way to the rubbish heap. I think his idea is that a bank of parallel nano-diodes (I'm assuming sub-micron die size) is exposed to the environment and as heat energy is absorbed, some electrons are excited and cross the PN junction, after which they have nowhere to go but into the load. I think it's just a variation on the old "energy of the aether" scam. I also fail to see how it's fundamentally different from a Peltier/Seeberg device- what he's describing is not in fact how a P/S device operates, I find it hard to believe a person could build something like that and measure a current out of it without there being some element of Seeberg effect present.
