MIT Combines Waste Heat Tech With Solar

The companies that turn heat into electricity usually try to harvest their heat in hot environments, like under the hood of a vehicle or on the outside surface of a steam pipe. Researchers at MIT have come up with an experimental device that could take heat directly from the sun. A group of researchers led by professor Gang Chen have devised a thermoelectric device that converts solar heat directly into power via the Seebeck effect. In the Seebeck effect, a sharp temperature gradient can result in an electric charge. (Solar thermal power plants work indirectly: heat makes steam and then turns a turbine.). The device is only 7 percent to 8 percent efficient and requires a difference in temperature of around 200 degrees Celsius, but it's more efficient than other, similar experimental devices. (See more in the Nature article.) The device consists of a thermoelectric converte...
