I'm calling bullshit. There's no way a Peltier element can exceed the coefficient of performance of the refrigeration cycle, at an affordable price, without turning the room into a hothouse.
Umm, a typical refrigerator cranks out a lot of heat. Why would would this be less efficient than that?
Check the efficiency of heat pumps.
Read the paper, it's linked below. This is solid state, there's no refrigerant. Heat pumps are efficient, and this IS a heat pump, which is far more efficient than the old school heat pump that uses a 'refrigeration cycle'. I'm with you on being skeptical, and it may be a long time from 'discovery' to production of a saleable device, but this IS a legit significant breakthrough.
