In contrast, thermoelectric built in wine cooler is environmentally safe, since they don't have any hazardous materials fueling the cooling process. Thermoelectric cooling relies on the Peltier effect, named for the 19th-century scientist who discovered it. When an electric charge is sent through two joined pieces of metal it creates a heat flux, and heat is transferred from one side of the device to the other. One side gets hot and the other side gets cold.
