A Lawrence Berkeley National Labs spin-out has developed the new technology, which is dramatically cheaper than existing waste heat conversions.
The U.S. consumes around 100 quads (100 quadrillion BTUs) of energy a year and 55 to 60 quads get dissipated as waste heat

From the sounds of it, this is only effective in VERY hot environments right now. They’re saying a car engine may not reach the levels needed to make it worth while. For large manufacturing plants and the like, this may be a good thing soon. But you won’t be seeing devices to stick on your car, CPU or in your roof any time soon.
Exactly. This is meant for big time industrial waste heat.
