waste heat

ElectraTherm, Inc., announced the first commercial installation of their new ”Green Machine”, an electrical generator that recaptures waste heat and turns it into electricity. The generator was recently installed at Southern Methodist University in Dallas, Texas. Since this system uses heat from other systems that is normally wasted, no additional energy is required to generate electricity, making it a truly “zero emissions” power source.

We renewable energy advocates love our silicon solar cells, but they come at a price: the process of making silicon generates massive amounts of heat and is a great big electricity hog. Now a company has found a way to make money capturing and using that heat, to make steam to run electrical generators.
