New Solar-Powered Device Can Pull Water Straight from Desert Air

Apparently, there are crystalline powders called metal organic frameworks (MOFs) that can be manipulated to control and bind different gases. One type of MOF, which was designed to excel at absorbing water, has made possible a device that can pull 2.8 liters of water out of the air per day for every kilogram of powder. Needless to say, this contraption would be a blessing for those who reside in the driest parts of the world.

آ…wringing water from the desert sky is now possible, thanks to a new spongelike device that uses sunlight to suck water vapor from air, even in low humidity. The device can produce nearly 3 liters of water per day for every kilogram of spongelike absorber it contains, and researchers say future versions will be even better. That means homes in the driest parts of the world could soon have a solar-powered appliance capable of delivering all the water they need, offering relief to billions of people.
