I didn’t know this, and it jumps out to me because 10k is pretty much the exact difference between room temperature and wine fridge tenperature - I wonder if this is actually not a horrible application for peltiers?

Found a wine fridge at the thrift store last month, pulled the model number, realized it was basically a Peltier cooler and a fan, and thus likely to be still operational. Powered up just fine, so...

$10 and an hour of deep cleaning later, and now we have a wine cooler in our basement. I don't recall the specs or power consumption offhand, but it does keep my beverage-of-choice a few degrees cooler than ambient. :)

I think the gotcha is that you need a beefy heatsink and fan (and power for the fan) to keep the hot side anywhere close to room temperature.
