Benefits
The primary goal of ATEGs is to reduce fuel consumption. Forty percent of an IC engine’s energy is lost through exhaust gas heat. By converting the lost heat into electricity, ATEGs decrease fuel consumption by reducing the electric generator load on the engine. ATEGs allow the automobile to generate electricity from the engine's thermal energy rather than using mechanical energy to power an electric generator. Since the electricity is generated from waste heat that would otherwise be released into the environment, the engine burns less fuel to power the vehicle's electrical components, such as the headlights. Therefore, the automobile releases fewer emissions.
Decreased fuel consumption also results in increased fuel economy. Replacing the conventional electric generator with ATEGs could ultimately increase the fuel economy by up to 4%.
The ATEG’s ability to generate electricity without moving parts is an advantage over mechanical electric generators alternatives.

Famous quotes containing the word benefits:
“One of the benefits of a college education is, to show the boy its little avail.”
—Ralph Waldo Emerson (1803–1882)
“It is with benefits as with injuries in this respect, that we do not so much weigh the accidental good or evil they do us, as that which they were designed to do us.—That is, we consider no part of them so much as their intention.”
—Laurence Sterne (1713–1768)
“While greedy good-doers, beneficent beasts of prey,
Swarm over their lives enforcing benefits ...”
