A Device to Pull Water Straight From Thin Air
“Is it possible to pull water straight from thin air?”
Water is one of the most vital components to many natural and industrial processes, whether it be keeping humans hydrated, running HVAC systems, or growing food. However, in many desert areas, water is extremely hard to come by. So how can we use our scientific mindset to solve this problem? Well, a team of chemists at UC Berkeley and MIT recently used a class of porous materials known as metal-organic frameworks to build a sheet that can absorb water vapor during the night, hold it during the day, and use the sun’s rays to release some vapor and siphon it to a condenser to create usable water! This system uses 3 liters of water per day for every kilogram of sponge-like absorber it contains and holds much promise to revolutionize access to basic drinking water.
