I'm not a physics major but it seems like the principle is that the water would flow behind the fan and as it's being warmed, it'll cool the air around it. You leave the tubing in the back in order to take that cooled air and cycle it around your room. The concept works...but yeah, try explaining that to a date..."What the HELL is that?!?!?"

Can't afford it? http://www.eng.uwaterloo.ca/~gmilburn/ac/geoff_ac.html Someone on another forum tried it and said it worked like a dream. It looks like crap, but a hell of alot cheaper than spending $300, $400 on an A/C unit. Rating: 5
