Getting Energy From Exhaust Pipes

Posted: Updated:

Researchers are working on a thermoelectric generator that converts the heat from car exhaust fumes into electricity. The module feeds the energy into the car's electronic systems. This cuts fuel consumption and helps reduce the CO2 emissions from motor vehicles.

In an age of dwindling natural resources, energy-saving is the order of the day. However, many technical processes use less than one-third of the energy they employ. This is particularly true of automobiles, where two-thirds of the fuel is emitted unused in the form of heat. About 30 percent is lost through the engine block, and a further 30 to 35 percent as exhaust fumes. Scientists all over the world are developing ways of harnessing the unused waste heat from cars, machines and power stations, in order to lower their fuel consumption.
