Abstract
Thermoelectric devices are now a days much popular regarding their combined effect of electrical and heat energy. Due to their capability to convert heat energy into electrical energy, they can be used as heat recovery units in engine exhausts. An assembly of thermoelectric modules when placed in the exhaust of engine can produce current. The phenomenon is governed by Seebeck effect and carried out in a single stage. This energy can be utilized in powering electric appliances running in automobiles. It can produce energy from waste heat of engine and thus providing a huge area of interest in automobile industry to extract energy using TEG.
