Cool off with a home-made air conditioner

Summer's here and the mercury is rising. That means air conditioning, and if you're like me, you've got that central A/C unit humming along and sucking up the dollars. But some areas in my home don't have A/C. My shop is a good example. OK, it was meant to be a two-car garage, but what a waste of space that would have been.

That's why I was pleasantly surprised to stumble across this site that shows how to construct a home- made air conditioner. The one featured here uses a small table-top fan, but I can envision one that uses a big box fan instead. More bang for your buck.

To build one of your own, here's what you'll need:

• A fan
• Ice chest
• Copper tubing
• Aquarium pump
• Ice
  

This set-up is actually quite similar to what I rigged up a few years ago when I used to brew beer. The wort had to be chilled quickly when emptying the brew kettle. Maybe I could rig it up to do both things at the same time. Hmmm...
