Waste energy converted to heat for $1 a watt

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


  1. 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.
