This Device Pulls Drinking Water Straight Out Of The Air — And It Runs Entirely On The Sun’s Energy

A new kind of water-capturing device could be a game-changer for some of the world’s driest places. It can pull water vapor out of the air at humidity as low as 20 percent — conditions that may be seen in the Sahara desert during its hottest months — and it can operate entirely off-grid, just using the ambient power of the sun. This means it could provide water for parts of the world likely to be most vulnerable to water shortages under future climate change, including areas afflicted by recurring drought.
