Thermopile, let extract some electricity from heat without steam

[Jacquesl]

I want to build a Thermopile to generate usable electricity with a heat source, like a small fire or something,

I can build something like this but, I only get 1 mA and an ant of a volt. And it subjected to 1700C blow torch, it sucks.

 

So does anyone have some info about that, would be nice, to light a candle and then your able to watch a DVD

Please describe the one you already built

look up RTG's. Yeah, they use a nuclear substance as a fuel but the way they convert the heat to electricity is what you want. just be sure to swap the heat source from radioactive stuff to a small fire or something, just to keep the feds off your back.

I’ve build one with copper wire and some iron wire looped around 6 times
