Innovative way to get drinking water in desert areas

Gist of the article is that in desert communities in Africa, they don't have infrastructure, or qualified repairmen to fix things when they break down, or money and equipment to dig deep wells.  Also, things like the Drinking Straw that will filter water when you drink it, means finding a pond or stream in the first place, and that could be miles away, plus, you don't really get enough for crops and things, it's just enough to get a few sips for yourself.

So this thing, which looks like a modern art sculpture, gathers water from the air and then the temperature extremes plus the design of the thing help to condense water vapour from the air.  The inventor claims that it can pull up to 25 gallons out of the air, daily.

As far as I can tell, this is mostly theoretical, but is being tested.
