Water from thin air!
.Researchers at the University of Texas at Austin have now demonstrated a low-cost gel film that can pull many liters of water per day out of even very dry air.

In tests, the gel film was able to wring an astonishing amount of water out of the air. At a relative humidity of 30 percent, it could produce 13 L (3.4 gal) of water per day per kilogram of gel, and even when the humidity dropped to just 15 percent – which is low, even for desert air – it could still produce more than 6 L (1.6 gal) a day per kilogram

That's really pretty impressive for a gel that costs about $2.00 per kilogram...
