Water Bottle Fills Itself From the Air

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."

And now imagine instead of being a bottle, it's a dense matrix made to maximize surface area and fresh air is pushed through with a solar-powered fan to accelerate the "condensation." Sort of like an evaporative cooling chiller in reverse. It could be really useful in humid tropical areas and a good alternative to desalination plants.
