Air2Water makes units that generate pure and filtered water from ambient atmospheric water vapor, allowing you to stick it to your local municipality (assuming you’re content with “up to six liters a day). Their website isn’t quite complete in some places, so it’s difficult to determine how well this might work in the desert or places where pure water is terribly scarce, but their residential unit should be available within the next few months. This technology has existed for some time now, but it’s only now that it appears to be making it to market.
