Drinking water extraction in the desert has always been a challenge for travelers, traders, and locals. Therefore, the invention by geniuses from the Massachusetts Institute of Technology and the University of California, Berkeley, did not go unnoticed by the media.
Device that Extracts Water from Air in the Desert
The news is intriguing because the invention is based not on theoretical concepts but has been tested in practice. After testing water extraction from air in real conditions, scientists announced their development to the world.
According to researchers, extracting water from air has been done before. The condition for a positive result was air humidity exceeding 50%. Here, however, they managed to create a mechanism that operates passively without electricity at humidity levels as low as 10 percent.
The principle of operation is simple. Encased in a special MOF (metal-organic framework) housing, a super-porous material attracts moisture and stores it for further use. The liquid is stored in pores and, under sunlight, condenses, after which it is collected by the user. The system is passive and requires no energy sources.
Field tests (in the Arizona desert) showed that a kilogram structure collected 250 milliliters of water per day. Although calling the device compact might be an overstatement, professionals assure that every gram of water is valuable in the desert. It is hoped that the Americans will not bury this innovation and that this life-saving device will reach residents of arid regions around the world.
