Thermal to electrical energy conversion is one of the most promising technology to produce the electricity from the unused waste heat. The major heat sources are coming out <gwmw class="ginger-module-highlighter-mistake-type-3" id="gwmw-15789733632288296042405">from</gwmw> industries, automobiles and thermal power plant.
