Here are some interesting topics for reading. While the forum is named "New Technologies" this is definitely old school technology put into practice.

This technology has been around for at least a couple of thousand years. Courtesy of our Arab friends.

I will look for some others. I have seen some pictures where the inventive Arabian folks made ice in the desert using this same principle.

Here is something that may be helpful.
