    No, it’s not air-flow. Peltier modules are “solid-state heat pumps”: You run electricity into them and one side gets hot while the other gets cold. Reverse the polarity of the electricity and the heating and cooling changes sides.

    So, as I said, sitting on one that’s cooling feels exactly like sitting on a piece of ice.

    My Cuisinart Yogurt Maker has one: It keeps the cultured milk at the optimum temperature for bacteria growth for twelve hours and then shifts to “cold” mode and chills the completed yogurt to stop the process. While it’s cooling, the “back” of the module radiates heat – there’s a fan in the yogurt maker that blows the heat out through a vent.
