This Carbon-Negative Generator Makes Drinkable Water out of Thin Air

Scientific Water News from Popular Mechanics – A high-volume water generator that can create water out of precipitation, and can be used in any climate, has been awarded a $1.5 million XPrize. The culmination of a two-year water extraction competition, the Skysource/Skywater Alliance was awarded for developing the machine that can produce, at minimum, 2,000 liters of water per day from the atmosphere using 100 percent renewable energy. Like many innovations, the new machine steals from nature. With the acronym WEDEW (for Wood-to-Energy Deployed Water System), it creates its own clouds within a box the size of a shipping container. Powered by wood chips and similar biomass, the WEDEW draws warm air from outside and sends it through an antimicrobial air filter to remove impurities. Once inside the box, the WEDEW introduces the warm air to generated cold air inside. This produces condensation. (more)
