Researchers are trying to combat the lot of emissions from the car exhaust and convert them into usable form. This can be done by converting wasted exhaust heat into energy that can help power the vehicle. This can be achieved from thermoelectric technique, which uses temperature differences to create electricity. This technology can be implemented to make vehicles as efficient as possible at the time when gas prices are soaring. Scientists have created a metal-plated device called thermoelectric generator that surrounds an exhaust pipe could increase fuel economy in a Chevrolet Suburban by about 5 percent, a 1-mile-per-gallon improvement that would be even greater in a smaller vehicle. This technology would help in management of the waste exhausts.
