Pulling clean water from dirty air


Pulling clean water from dirty air Today’s Video of the Day from King Abdullah University of Science and Technology describes a device that could potentially pull drinking water out of the air.

There is nearly 13 trillion tons of water stored in the atmosphere across the planet, which is a huge untapped resource of clean water. Pulling clean water from dirty air is a new way that scientist have learned to take devices to pull out the impurities and make clean water.  Off-Grid Devices Draw Drinking Water from Dry Air. Technologies that pull moisture from the air are now solar-powered. There are millions of people without clean water.

The new technology, developed by Peng Wang from the King Abdullah University of Science and Technology (KAUST), is designed to serve as a low-cost method for collecting clean water in remote areas. Billions of people lack access to clean water for all or part of the year or must travel far to collect it. Extracting water directly from the air would be an immeasurable boon for them. But existing technologies generally require a high-moisture climate and a lot of electricity, which is costly and often unavailable.  Clean air is good for people to breathe. On a hot day with no wind, the air can feel heavy and have a bad smell. Once in a while, the air can even make your chest feel.

The study is published in the journal Environmental Science & Technology.
