Scientists have successfully extracted water from the air in the desert
The scientists were able to create a device for the collection of water from dry desert air. To do this, they need only to heat from the sun. Their invention could change the lives of 2, 1 billion people who lack clean drinking water. The main advantage of the invention is that for it to work requires neither electricity nor rain. Previously, we reported on an important invention. Finally, it could be tested.
A group of scientists from the University of California at Berkeley have created a device of a porous MOF material (organometallic design), placed in a clear plastic box. Water vapor from the atmosphere collected through MOF material such as a sponge, after which the water evaporates and is collected in a special tank.
The researchers conducted a test of your device in Scottsdale, Arizona. During the day, they collected about 7 ounces of water. This is quite a bit, but scientists say that their invention is extremely easy to scale.
MOF material consists of metal and organic carbon compounds. Its peculiarity existence of a large number of tiny air pockets between the molecules of different types. This allows the material to collect the condensate and liquid absorption effectively. Especially effective is he doing it at night, when the relative humidity increases. As the sun rises, the heat causes the evaporation of water from the sponge material, but since it is enclosed in a box, the vapor is collected and again becomes water entering the tank. After that it can be used for drinking.
water collection devices already exist, but this is the first device that requires so little resources. There is a small problem - the high cost of production MOF, since at this point the material is produced with the use of costly zirconium. However, researchers are working on the MOF using much cheaper aluminum.
At any time in our atmosphere sekstilliardov contained 13 liters of water. Getting affordable way to use it can solve many current and future problems of the people.
