I'm always fond of soda that is ice cold, but often for some reason don't have any in the fridge. I have a small can chiller that works by rotating the can in a tub and you put ice on top which lay on the can. It does a pretty good job in 2 minutes or so, but is noisy and wears out rechargeable batteries pretty quick.
I wonder if some sort of peltier setup could chill a can without the noise and ice? Does anyone have any experience with using peltier's in a project? One issue is the connection between the can and the peltier. Any thoughts?
