There was a film that collects drinking water from the air, even in the desert

The researchers used materials for the film that cost as little as $2 per kilogram.A kilogram of film

It can produce more than 6 liters of water per day in areas with a relative humidity of less than 15% and 13 liters in areas with a relative humidity of less than 30%.

More than a third of the world's population lives in arid regions where there is significant water scarcity. Scientists and engineers at the University of Texas at Austin have come up with a solution to help fix this.

The researchers used renewable cellulose and cognac gum as the main hydrophilic (water-attracting) framework.The structure of the film is similar to chewing gum with pores - this appearance acceleratesmoisture capture process. 

Another developed component isthermosensitive cellulose with a hydrophobic (water resistant) effect when heated. It helps to get the collected water quickly, so the total energy cost for water production is kept to a minimum.

According to the researchers, the reaction itself is very simple, so it is easy to scale and use en masse.
