ABSTRACT
Thermoelectric devices convert temperature gradient to electric voltage, and vice-versa. With the rising awareness about global warming and the scarcity of fossil fuels, these devices recently drew worldwide attention. Thermoelectric devices have emerged as promising power generating source from waste heat without burning any extra fuel. Due to this green feature and distinct advantages, the thermoelectric technology is instrumental in designing simple, compact and environment friendly system for harnessing waste heat emitted by automobile exhaust. The project is based on an array of thermoelectric modules which convert thermal energy into electricity for the purpose of charging small batteries etc. During this research, an assembly of thermoelectric modules is tested at various RPMs of the engine and several temperature gradients with a goal of proving its effectiveness in producing current for electrical parts running in an automobile. The research data proved that their current conversion efficiency is technically and economically practical for small applications.
