The air-conditioning system

  • The air-conditioning system of the future may work through so-called thermoelectricity. The thermoelectric device is very small and very quiet. It is composed of tiny "pairs", each of which is composed of a pair of semiconductors connected by parallel current. When flowing directly through them, these galvanic couples produce cooling at one end and heating at the other end. This is called the Peatier effect. When the current is reversed, the cooling and heating effects are reversed. When you find a cheap way to produce such miniature thermoelectric devices, they may cool and heat your entire house. - rovsun
