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."

I did. It's roughly 0.7mL per hour for a 710mL coke bottle; takes around 40 days to fill it up.
