A new way to produce power
WEST LAFAYETTE, INDIANA - Purdue University scientists have developed a device designed to produce electricity from the heat a car's engine produces, potentially enabling it to improve mileage by reducing an engine's workload.
It produces an electric current by maintaining a steep temperature difference between two chambers, with one harvesting heat from exhaust gases that can reach 1,300 degrees.
The scientists say the technology also could harvest wasted heat in homes and power plants as well as improve solar cells.
