Turning Excess Heat Into Energy
'Waste heat' is a hot area of research as an alternative energy source. Providers say they can turn excess heat produced by machines in factories into clean electricity.
In one factory retrofit, the company Recycled Energy Development (RED) is projecting that they can produce 1/3rd of the power a West Virginia factory needs purely from the excess heat they are already generating.
Michael Kanellos writes, "The U.S. consumes around 100 quads (100 quadrillion BTUs) of energy a year, and 55 to 60 quads get dissipated as waste heat, according to [UC Berkeley professor] Arun Majumdar."
"Thus, there is a lot of waste heat out there and it could be cheaper than solar."
