Alphabet Energy solution is tetrahedrite: an abundant, naturally occurring mineral that also happens to be more efficient on average than existing thermoelectric materials.
Ali Shakouri, a professor of electrical and computer engineering at Purdue University, says that tetrahedrite has promise
tetrahedrite costs about $4 per kilogram, whereas other thermoelectric materials cost between $24 and $146 per kilogram.
if tetrahedrite can be used to harness heat from car exhaust. Scullin says that other thermoelectric materials have achieved typically about 2. 5 percent efficiency in cars,
but tetrahedrite could reach 5 to 10 percent efficiency. hese aren incremental improvements, he says. heye really huge improvements that make really significant impact. l
