Here’s a cool green machine that makes power from wasted heat.
It’s a simple concept really, sorta like turbos in cars. Turbos work by running off the wasted exhaust heat and fumes to rotate it’s rotors while the green machine does the same thing. It’s a turbo for any other applications.
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.
