With rapid industrialization, the world has seen the development of a number of items or units, which generate heat. Until now this heat has often been treated as a waste, making people wonder if this enormous heat being generated can be transformed into a source of electric power. Now, with the physicists at the University of Arizona finding new ways to harvest energy through heat, this dream is actually going to become a reality.

Great efforts have been made to improve public awareness about energy savings. Energy efficient appliances have replaced power consuming equipment. Millions of compact lamps and solar water heaters have been used, while many power saving models have been applied to factories and smart/green buildings.
