Waste heat could power computers, cell phones
Close to 60 percent of the energy produced by burning fuels or generated by power plants is lost as excess heat. Computers, cars and cell phones all have to get rid of excess heat to run properly, creating a significant energy waste. Researchers at MIT believe they’ve developed a way to reclaim a majority of that wasted energy and turn it into electricity.
