The Pell cells in earlier posts have been used for a number of years in portable coolers. You plug into the cigarette lighter in your car and the inside gets cold. Turn the power around and the inside gets hot. The cell is attached to a large heatsink that is molded into the outside of the cooler, no fan is needed. It is not an efficient way to get cool but it does fill a niche.
