Solar-powered system extracts drinkable water from "dry" air
Axios reporter Bryan Walsh highlights how MIT researchers have developed a new solar-powered device that can extract drinkable water from the air and "could help alleviate water scarcity in some of the world''s driest regions." Walsh notes that the new design "makes use of a more common material called zeolite, doubling its capacity to generate water."
Researchers in Australia Develop a ''Water Harvester''
The device absorbs water from the atmosphere. Solar energy or heat from other industrial processes can be used to produce hot, wet air. After heating, the air cools, producing water for drinking or watering crops. Behdad Moghtaderi of the University of Newcastle''s Centre for Innovative Energy Technologies told VOA how the technology operates.
