Water Bottle Fills Itself From the Air 173
mbstone writes "The Namib Desert Beetle generates water from water vapor via its shell, which has alternating hydrophilic and hydrophobic bumps which channel water droplets into its mouth. Scientists at MIT developed a self-filling water bottle using this technology, and have announced a contest for the best design of a countertop water-from-air generator."

My point is that a temperature gradient is far cheaper and available to poor third world desert countries where such a system is required. This technology is neat but not all that practical. Still a combination of the two systems, ie. lining the inside of underground pipes with this substance and letting the wind push air through might have a much higher rate of condensation and could be used for commercial and military operations in the desert.
