Dirt-cheap thermoelectrics

In Science, technology on January 25, 2013 at 7:55 am

Researchers at Michigan State University found a way to make efficient devices that convert heat into electricity using common minerals found in dirt. They process them by grinding and applying heat and pressure, which is far, far cheaper than the usual methods of creating thermoelectric devices. Because current technologies waste copious heat, thermoelectrics seem like a straightforward route towards higher efficiency energy use.
