The device would look a little like a "world's greatest grandpa" foam beer can cozy or whatever, but would plug into the wall, and within 2 minutes chill a can of coke (or o'douls) to 2 degrees!
Hopefully we could do this without a big nasty heat pump and do it cheaply and just have it plug into
120V AC!

Any of our resident chemistry folks know how much energy it takes to reduce a 12oz. can of liquid from room temp to 2°C in two minutes? Could a Peltier device-equipped one-can fridge work or would you need to submerge the can in a chilled brine (like the rapid wine coolers I've seen at upscale grocery stores)? |

Both self cooling and self heating cans exist - the self-heating kind are pretty easy to manufacture, and are readily available, typically with coffee (of sorts) in them. |
