There was a film that collects drinking water from the air
The researchers used materials for the film that cost as little as $2 per kilogram. A kilogram of film can produce more than 6 liters of water per day in areas with relative humidity less than 15% and 13 liters in areas with relative humidity up to 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 renewablecellulose and cognac gum as the main hydrophilic (water-attracting) framework. The structure of the film is similar to chewing gum with pores - this appearance speeds up the process of trapping moisture.
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, because it is easy to scale and use in large quantities.
