I saw on a TV show some time ago about a university student somewhere (full of good information in that statement) that had made tiles to place in public that generated electricity when people walked on them. I have to say I said to myself "yeah, right - practical as hell"... with a device like this... hmmm...

I kinda' believe there must be a device coming on the consumer market that uses this thing or a private company has it embedded in a product. It just doesn't strike me as a device that would get a budget just because someone thought it *could* make money. I did a Google search and didn't find it referenced in anything, yet...
