According to the studies, the air surrounding us contains more than 16 sextillion liters of water. Therefore, the air is, without any doubt, a perfect source for fighting drought which is affecting more and more regions due to climate change, especially. Now, the scientists from the University of California, Berkeley (UC Berkeley), came up with a material that is capable of extracting water out of the air.
The principle behind this technology is the well-known condensation principle but, despite the fact that this method is employing a very easy-to-understand physics principle, implementing it is quite challenging.
According to the researchers, the material used for extracting water out of the air needs to be colder than the ambient, thus, the question that arises here is “how would be possible to keep this technology cooler than the air surrounding it, in the middle of the desert?”
One way would be to create a cooling system, but it will consume a lot of power, thus, it won’t be suitable for remote zones such as deserts.
Scientists from the University Of California, Berkely, found a solution for extracting water out of the air to fight drought
In a report issued on June 8th, the scientists from the UC Berkeley explained how they were successful in extracting water out of the air in the Arizona desert.
According to the report, the researchers developed a box and spread over it a material made of organic material and the metal zirconium.
The material, developed at UC Berkeley, is porous and contains hundreds of internal channels. Therefore, when night comes and the air temperature decreases and the air humidity increases, the air condenses on the material’s surface which, through its internal channels, collects the water from the air.
The system was successful in extracting water out of the air in the Arizona desert and is designed to help the fight against drought which “conquers” more and more regions due to climate change.
