What if Your Refrigerator Was Twice As Efficient and Completely Silent?

APL’s CHESS thin films nearly double refrigeration efficiency. The scalable materials could transform cooling and energy-harvesting technologies. Scientists at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, have created a new solid-state thermoelectric refrigeration system that is simple to manufacture and twice as efficient as devices built with standard bulk thermoelectric materials. As [...]
