A Device that Can Pull Drinking Water From the Air

A system that uses “Skywater, a large box that mimics the way clouds are formed” and powers it with a biomass gassifier, a low-cost source of energy:

When the gassifier is filled with wood chips, coconut shells, or whatever biomass is locally available, a process calls pyrolysis vaporizes that material. That makes the system hot and humid, the ideal environment to run the air-to-water machine. As it generates power, it also produces biochar, a charcoal that can be added to soil to store carbon and help plants grow.
