Thermoelectric Generators for Waste Heat Recovery in Vehicles

Quick fact

Typical automotive TEGs can generate up to 1 kW of electrical power from exhaust heat, which can improve fuel economy by 2-5% depending on driving conditions.

Why this is interesting

Your car's engine wastes about two-thirds of the fuel's energy as heat. What if some of that heat could be turned back into electricity to power your car, saving fuel and reducing emissions?
