Putting a peltier to good use

[Groltz]

I can only wonder if the Bartender has one of these.

Not a bad idea. It must kill the batteries pretty quick though. A 118W, 127 couple cooler running at 9.6 volts draws around 7 amps. Even with the highest capacity NIMH batteries that's only about 12 minutes run time. Peltiers have a way to go before they're practical in battery powered applications. By my estimates keeping a beer at 0°C in an insulated container has a heat leak of <5 watts. If they could ever make a Peltier cooler that operates near the Carnot efficiency this would only require less than a watt of power even on a very warm day, making it practical for battery power. Current coolers require about 10 to 20 times that.

I have a pair of 172W TEC's, finding a switching power supply for them at an affordable price is not a simple task.

That is just beautiful. How about powering several of those coolers through an umbrella with solar cells on top?
