Water harvester (image) University of California - Berkeley Share Print E-Mail Caption The latest version of UC Berkeley's water harvester blows ambient air over a cartridge filled with MOF, which is visible inside the plexiglass box. The MOF pulls water from arid air, which is then removed from the MOF by mild heating. The concentrated water vapor is blown out through the tube at right to a condenser. This process produces water for drinking using only solar panels and a battery, even in areas as dry as the Mojave Desert.
