MIT's high-tech 'bubble wrap' turns air into safe drinking water — even in Death Valley

"MIT researchers have created a high-tech "bubble wrap" capable of collecting safe drinking water directly from the air — even in Death Valley, the driest desert in North America.
The new water harvester is a major step towards providing safe, accessible drinking water to people across the globe — and works wherever you may find water vapor in the air, scientists said in a new study published June 11 in the journal Nature Water.
The water harvester is made from hydrogel (a highly water-absorbent material) that is enclosed between two layers of glass — much like a window. At night, the device absorbs water vapor from the atmosphere. During the day, the water condenses on the glass thanks to a coating that keeps the glass cool. The liquid water then drips down the glass and is collected in a system of tubes."
