The company intends to make units that range in size from 30 kilowatts to 500 kilowatts, enough to offset electricity use at an industrial facility. A 50 kilowatt unit can generate roughly what 40 U.S. homes consume.

'Green machine' makes power from waste heat

Thermoelectricity--the practice of drawing electricity from heat--is getting a real-life work-out.

ElectraTherm on Thursday said that it has installed a 50-kilowatt machine that uses industrial waste heat as its "fuel."

The company says that the ElectraTherm Green Machine, installed at Southern Methodist University in Dallas, will recoup its purchase cost in three to four years with electricity costing three or four cents per kilowatt-hour during that time.

The machine uses an organic Rankine cycle to heat liquids which are turned into a vapor that turns a turbine to make electricity.

The thermoelectric effect has been known since the … Read more
