With rapid developments in idustrialization, the world has seen many items that generate heat. This heat has often been treated as waste. Now people are wondering if this heat can be used as a source for electric power. Physicists at the University Of Arizona have found new ways to convert heat waste in electricity. The research team at the university have been working on harvesting heat waste into energy. There findings were featured in the September 2010 issue of the scientific journal. There are many advantages to this. One of them is elimination of ozone depleting materials. The project also utilizes waste energy and advantages over solar energy because molecular devices help harvest from the sun and reduce dependence on photovolic cells. For the team at the University Of Arizona, their dream could actally become a reality someday.
