Automobile exhaust energy utilization

Waste heat recovery is one of the promising methods as one of the energy sources that can be employed as it is abundantly available in the exhaust gases emitted from industries automotive engines braking mechanisms of automobiles etc. It is estimated about 30 to 40% energy can be harnessed from these exhaust gases by employing the principle of Peltier modules. This energy can be further utilized to generate power that can be utilized for both heating and cooling purposes.
