An engineering student, Geoff, in Ontario, Canada lived in housing without AC. During the Summer, as temperatures rose, so did his brilliance. You can read more about his Homemade Air Conditioner. It created quite a buzz in Canada, and I'm very thankful that he shared his idea with the world.
Trying to follow Geoff's original design, here's what I did.


How it Works
To get it started you just prime the siphon by sucking on the end where the water will drain. Once it starts pouring out, you know it's working. After you have the siphon working, the ice cold water flows from the bucket of water through the copper tubing attached to the fan's surface, and out to the drain. The copper tubing gets icy cold. The fan then blows over the tubing which in turn makes the air very cool.
According to Geoff, if you have a decent sized water container, the cool air should last for about 3 hours depending on how fast your siphon is. He also says that it can cool off a room in about 20 min. We will be using ours for the first time tonight, so I'll let everyone know how it goes.
