PASADENA, Calif., March 22 (UPI) -- U.S. researchers say they've identified a new thermoelectric material that may lead to efficient conversion of heat into electricity and vice versa.

A thermoelectric material generates electricity when there is a temperature difference between one end of the material and the other.

Researchers at the California Institute of Technology have reported a promising new thermoelectric material can be made from copper and selenium, a solid that exhibits liquid-like behaviors due to the way its copper atoms flow through the selenium's crystal lattice.

"It's like a wet sponge," researcher Jeff Snyder said. "If you have a sponge with very fine pores in it, it looks and acts like a solid. But inside, the water molecules are diffusing just as fast as they would if they were a regular liquid.

We really do need some new breakthroughs in alternative energy... coal, nuclear and petroleum really need to start going the way of the dodo sometime in the near future :)

That doesn't sound like a new energy source, per say, but just a way of making existing energy sources more efficient. (I know you're not the one that wrote the headline, though.)
