Someone Clever tell me why this isn't possible.

Why hasn't a material been manufactured that takes all its heat energy and transfers it to electrical current.

So you have a material that is close to absolute 0 all the time pumping out current, and it just keeps taking energy from heat to do this. This would mean that the material would be constantly be cold, and the area around it.

Like a solar panel does with light, why not a material with heat??

You could also maybe solve global warming this way ?

Long time since I've had to think about this, but you seem to be describing a perpetual motion machine of the second kind?

Seem like quite a complicated subject, but basically using heat to move material or in my case electrons.
