The latest Xprize winner harvests drinking water from the air
Judges have chosen the winner of the Water Abundance Xprize, and it might just be vital to solving some of the world's most difficult shortages. The Skysource/Skywater Alliance has earned $1.5 million for WEDEW (Wood to Energy Deployed Water), a system that converts air into drinking water using natural resources for power. The heart of the technology imitates clouds by cooling warm air and collecting the condensation in a tank. A biomass gassifier, meanwhile, vaporizes wood and other organic material to generate the necessary power for the system.
