Episode: Microwave-Sized Harvester Pulls Water from Desert Air
Description: Researchers from the University of California - Berkeley have developed a new solar-powered water harvester that's the size of a microwave and pulls water out of the air in areas as dry as the Mojave Desert. The harvester blows air over a cartridge filled with metal-organic framework (MOF). The framework pulls water from the air, which is then removed by heating it. Next, the concentrated water vapor blows through a tube to a condenser. The harvester can pull more than five cups of water from low-humidity air per day for each kilogram (2.2 pounds) of water-absorbing ma...
