Welcome to summer (if you're in the Northern Hemisphere anyway)! Here's a quick video on how to make an easy, portable air conditioner - which only uses as much energy as an electric fan.

The basic principle is pretty simple: Waterproof box, vent holes, ice, electric fan - a quick search of Google will give you a wide variety of designs following the same basic concept.

So, if you don't have the $ for an actual air conditioner, don't want to pay the energy bills that come with running one or if you need one temporarily to cool an area - this is about as easy as it gets (if you want hard, put in a hydrothermic cooling system).
