Nanotechnology could recover energy

WEST LAFAYETTE, Ind., April 17 (UPI) -- U.S. researchers say a new technique could harvest energy from hot pipes or engine components to recover energy wasted in factories, power plants and cars.

Scientists at Purdue University say they've used nanotechnology techniques to coat glass fibers with a new "thermoelectric" material they developed.

When thermoelectric materials are heated on one side, electrons flow to the cooler side, generating an electrical current.

Fibers treated in this manner could be wrapped around industrial pipes in factories and power plants, as well as on car engines and automotive exhaust systems, to recapture much of the wasted energy, the researchers said.
