high output metal to metal thermoelectric generator? Answered
I saw this on youtube:
He has like 16 wires in this setup, and it generates enough power to light an LED... how much power could you get with some more wires? Say 1600?
Does the thickness of the wire matter?
Sorry to make you watch the youtube video, if you don't want to, here's what's going on. This guy, Nyle, uses copper wire lengths which he has heated at one end and cooled to coat each end of each length with copper oxide. He then bends the wire so that two ends of copper oxide-coated wire are touching and another end is about 3 inches from the junction. By heating the loose end, and touching one wire to another, he's able to generate enough current to light an LED... pretty neat!
