Thermoelectric generators rely on temperature differences to produce electricity. They have a hot and cold side, and when heat is transferred from one side to the other, electrical power is generated.

For instance, the generator output was estimated to be 56 W when deployed in a car. However, a helicopter exhaust could generate 146 W of energy, the equivalent of 12 lithium-ion batteries.

The Heat Coming Out of Your Car’s Tailpipe? Some Can Be Turned Into Electricity. Share. Resize. Listen (2 min) ... called a thermoelectric generator, designed to do just that.

Power from heat: A thermoelectric generator that converts waste heat from a car’s exhaust system into electricity could improve fuel economy.

In simulations mimicking high-speed environments, the waste-heat system demonstrated great versatility; their system produced up to 56 W for car-like exhaust speeds and 146 W for helicopter-like ...

If 75% of this heat goes to the exhaust, then we have a ‘heat stream’ of 36 kW compared to atmospheric conditions, so the conversion to (lets be generous) 56W equates to 0.16% of the exhaust heat.

Electricity From The Exhaust Pipe Date: June 4, 2008 Source: Fraunhofer-Gesellschaft Summary: Researchers are working on a thermoelectric generator that converts the heat from car exhaust fumes ...

And my concept of a micro-generator PHEV would help with another major issue of pure-electric cars: heat. As in the kind of heat my old VW didn't have much of. And that's an issue that, so far, it ...

New thermionic generator overcomes the 'space-charge problem'. (Courtesy: J Mannhart/MPG) A new type of thermionic generator that turns heat or light into electrical energy has been developed by ...

If you have a car, you have a generator. If a hurricane or flood hits, what should I plug in, ... You pull it out, you attach it using the built-in heat-proof booster cables.

A car dealer dragged a generator for four hours through the snow to power a shelter in Buffalo, NY. Vive Shelter was without power for 27 hours after Buffalo was hit by a blizzard.
