The purpose of this Instructable is to create a personal air conditioner for outdoor use. The 'cool' comes from an ice/water reservoir stored in a thermos. Copper tubing is used as a heat exchanger, a small water pump moves the ice water and a small fan distributes the cool air. The entire system is run from a solar panel from Brown Dog Gadgets. An off-the-shelf USB Y connector can be used to connect the components so that no soldering is needed.
Any insulated cooler can be used. It should be portable and ideally have a pouring spout at the top to allow the copper tubes to go in an out without a lot of drilling. The same spout can be used to collect any condensation on the copper coil and add that water to the reservoir.
