Before I get started, I have to give props to Geoff Milburn, at http://www.gmilburn.ca/ac/
whose plan it was I copied. I'm not smart enough to think up something like this on my own. That being said, one of the places I work has no AC, but I'm allowed to have fans, so this seemed like a good project for me. It's not perfect yet, but it does cool the air better than just a fan.
