Electricity from Waste Heat-Ener-G-Rotors' system harvests energy at lower

The company replaces the turbine in a typical electrical generator with a device called a gerotor, which it claims to have made "near frictionless." "If this works, it's so huge," says Bob Bechtold, president of Harbec Plastics, one of Ener-G-Rotors' potential customers. "I've been dreaming about the concept of using [low-temperature waste heat] ever since I first knew what it was about . . . It's all about using what we have more completely."
