A New Kind of Alchemy: Water from Air

The inverted pyramid you see pictured here is an invention I've read about in a few places called the WatAir. Created by students at the Technion in Israel for a world-wide competition on water gathering, it can draw 12 gallons of water overnight, drop by drop, into the bucket below - IN THE DESERT! This innovation has the potential to transform life for millions, if not billions, of planet-dwellers without safe access to water. The water, since it is distilled straight from the air, is uncontaminated.
The WatAir can be made from a variety of lightweight materials, so it is easily installed in remote places. I don't believe it's in production yet, but what a great contribution. Think of how many hours women will save every day if they don't have to lug water from afar.
I like that it literally turns the pyramid idea on its head, just like the paradigm shift of the early Israelites traveling in the desert escaping pyramid-building. Let's hear it for designers Joseph Kory and Eyal Malka!

wow, that's cool. what does it cost, and what kind of maintenance does it require? Does it require power? These could be obstacles to widespread implementation.
