Turning Car and Helicopter Exhaust into Thermoelectric Energy

Posted by Dronerator
Combustion engines, the engines in gas-powered cars, only use a quarter of the fuel’s potential energy while the rest is lost as heat through exhaust. Now, a study published in ACS Applied Materials & Interfaces demonstrates how to convert exhaust heat into electricity. The researchers present a prototype thermoelectric generator system that could reduce fuel […]
