New tech harvests drinking water from (relatively) dry air using only sunlight
A new device the size of a coffee mug can generate drinkable water from desert air using nothing but sunlight.
“With this device, you can harvest the equivalent of a Coke can’s worth of water in an hour,” says cocreator Omar Yaghi, a chemist at the University of California, Berkeley. “That’s about how much water a person needs to survive in the desert.”
