I saw a story a few years ago where they built concrete towers in the desert in Saudi Arabia. At night the air would flow through the towers and moisture would condense on the inside and drip down into a collector. I have always been fascinated by this and wish I could try it out nyself.

See my post #21 and it is interesting to hear about the
Saudi towers. I hadn't heard about them.
