Scientists at the University of California at Berkeley (USA) have developed a device that can capture and collect water molecules in the air, using sunlight as an energy source. The results of the research were published by the journal. nature water.
The development is an organometallic framework МОК-303, a three-dimensional framework consisting of Al(OH) and 1H-pyrazole-3,5-dicarboxylate. This material is very porous, which allows it to collect water molecules from the air at low relative humidity.
Disc-shaped membranes with a diameter of 38 mm and a height of 0.8 mm were placed in a cartridge placed in the open air to capture atmospheric water. It was moved to the body of the device during the day. Thanks to solar heating, water is released from the membranes in the form of steam and is condensed in an aluminum radiator, then flows into a collection vessel.
This development has been successfully tested in Death Valley (the Mojave Desert in the southwestern United States, on the border of California and Nevada). Tests have shown that the device can collect up to 285 grams of water per kilogram of IOC per day at temperatures of 21.9-60.7 degrees Celsius and 9.4-36% RH.
