Not that mad scientists haven't figured out
a way to convert waste heat into energy
, but a team from Ohio State University has developed a new material that does the same sort of thing... just way, way better. The new material goes by the name thallium-doped lead telluride, and at least in theory, it could actually convert exhaust heat from vehicles into electricity. According to a new report about to hit the journal Science
, the material packs "twice the efficiency of anything currently on the market," though it still seems as if it's a good ways out from being ready for commercial applications. Nanotechnology geeks -- you've got a real treat waiting in the read link.
