Over two billion individuals don’t have a safe source of potable water. A team of researchers from the University of Texas at Austin conducted a research and discovered that you can extract water from thin air by food scraps, and they call it “ atmospheric water harvest”, with a goal of alleviating global air scarcity, by transforming polysaccharides which are complex carbohydrates into affect affected hydrogel sorbents. They made molecularly functionized bio mass hydrogels by using food scraps to seashells not have the ability to absorb massive amounts of water weight and by doing so created a universal molecular engineering strategy that converts natural materials into high efficiency sorbents.
