Homebrew Air Conditioning for Under $25

Posted by timothy on from the ice-is-free-after-all dept.

inkey string writes "Summer has arrived, and I've been busy slowly overheating in my student house without central air. I decided to put my thermodynamics classes to work however, and produced this ~24$ homebrew air conditioner. It'll cool a room to a comfortable level in 15-20 mins, and will run for a few hours on a garbage pail full of water. It's cheap, environmentally friendly (just fire the waste water off to your garden), and makes a good one hour project for a quiet evening."

    I hope his server isn't in his room, because all the thermodynamics courses in the world wont teach you about slashdotting.

    I think that his garbage can full of ice water should at least have a few cold beers. I mean really, he's in college!

    Hey! California has amazing redeeming value. Without it, all those idiots would be living with the rest of us!

    It's not a minor nit-pick. Its a major flaw. His setup is so much more inefficient than even a cheap ($100) AC.

    If he wants to be cheap, why not just take an old fridge ($20), remove the doors, and use the fridge to block the door to his room? Leave the coils facing out into the hallway, and his room becomes cooler - plus the light will always be on, so he can see wtf he's doing.
