Actually, I'm not impressed by the portable version. More interesting to me is the possibility/feasibility of scaling it up (a lot) to provide fresh water that many of the villages and villagers in developing nations need instead of the polluted and disease infested water they are forced to use.

I'm thinking of the many villages in the tropics that have no access to clean water. A fixed installation might be able to produce significant amounts of potable and (relatively) safe water day in and day out. A "well" that produces water from the tropical air. . .how many lives would it save?
