Ugly and effective, this air conditioner costs as much as you'd pay to run a fan and water the lawn at the same time.

Salvage a computer fan, power it with a solar cell, and surround it with wet cloth. That's the gist of this mini solar A/C. At $5, it's cheap too. You could place a half dozen of these around the house. Just make sure they match the curtains.
On smoldering hot days, Rob Patto derives smug satisfaction knowing that the same sun that keeps him huddled indoors is also cooling his home. Here, he describes how he gutted an evaporative cooler and cobbled his A/C together from salvaged and new parts. Be sure to read Patto's separate instructions on setting up solar panels to power the unit: http://www.instructables.com/id/DIY-Solar-Setup/
Using only a tin can, a CD, a computer fan and ice, this is a brilliant design for a tiny air conditioner. The best thing about these instructions are that their maker doesn't speak English as a first language, so they're concise and rely heavily on photos.
