Generating electrical power from waste heat

Posted by in categories: energy, transportation

Directly converting electrical power to heat is easy. It regularly happens in your toaster, that is, if you make toast regularly. The opposite, converting heat into electrical power, isn’t so easy.

Researchers from Sandia National Laboratories have developed a tiny -based that can harness what was previously called waste and turn it into DC power. Their advance was recently published in Physical Review Applied.

“We have developed a new method for essentially recovering energy from . Car engines produce a lot of heat and that heat is just waste, right? So imagine if you could convert that engine heat into for a hybrid car. This is the first step in that direction, but much more work needs to be done,” said Paul Davids, a physicist and the principal investigator for the study.
