Elfich: The Peltier effect is real. The idea is to use electrical power to transmit heat from one side of an object to other side of the object. The problem is that Peltier cooling is horribly inefficient compared to standard air conditioning. Normally Peltier cooling is restricted to specialized applications where the conditions do not allow for standard cooling techniques.Peltier cooling for humans has been tried before. I think there were some prototypes built into chairs at one point (the back of the chair got hot).Until someone gets the efficiency up it will remain a specialty application.
