The biggest problemwith pelts is obviously the cost and effecieny of the power supply. Now, since peltiers are very simple loads and care very little about the quality of the power coming to them, why not hook 10x 12 volt pelts or 5x 24 volt up in series, thus making a 120 VDC peltier. Then simply take 2 or 3 large bridge rectifiers hook them to the 120 VAC line, then hook the peltiers to the other side. This would cost very little and provides loads of peltier cooling. It is also very small. The only problem I can forsee is that you would be saying "wtf am i supposed to do with 5 or 10 pelts?". Also 120 VDC is very dangerous as it is not a self quenching arc. Any suggestions/thoughts to my idea?
