What if there was a way to cool your home, car, or workplace without the need for a big, loud, and energy-hungry machine? What if this device also was entirely solar powered with no moving parts? Sound to good to be true?
This Instructable will cover the method I used to build a prototype Solar Air Conditioning Unit. This unit is a prototype, and was only ever meant as a proof of concept that my idea could work. There is a lot of testing that needs to be done to see how this idea can be used in more practical applications.

.:| This Instructable was intended to be entered into the Green Technology Contest. However, because this project uses no electronics, it was not accepted. I entered this into the Hurricane Laser Contest instead, and if you like this Instructable, it would be awesome if you would vote for it in the contest! Having a laser cutter would be awesome because it would allow me to build things better and more quickly to be able to share them with the community! |:.

Step 1: "Why?"
-I'll take this point to say that if you don't care about specifically why I built this, then move on to the next step, no hard feelings : )
My car sits in the sun all day, and has a black interior. I'm sure you already know that dark colored things tend to get hotter when they sit in the sun than lightly colored things. Additionally, windows do a funny thing when light hit them, and serve as a sort of insulation, so that the air in my car actually gets hotter than the outside air temperature. Both of these factors cause me to start sweating almost immediately upon entering my car, which isn't very attractive when going to work, nor very comfortable.
Therefore, I was thinking of different ways I could cool down my car while it sits in the driveway. Leaving all my windows down isn't very practical for safety reasons and letting bugs in. A foil sun shade that would sit on my windshield would be annoying to put up and take down. I also had a vague idea of how a Solar Air Conditioning Unit could work, and decided that a car would be the perfect test medium for my concept! The car would allow me to attempt to cool a small amount of space, in a fairly controlled setting, and potentially save me from a very uncomfortable commute.
