“Friesen, an associate professor of materials science at Arizona State University, has developed a solar-powered hydropanel that can absorb water vapour at high volumes when exposed to sunlight. 

It is a modern-day twist on an approach been used for centuries to pull water from the atmosphere, such as using trees or nets to ‘catch’ fog in Peru, a practice that dates back to the 1500s and is still being used today.

Amid the flashy transparent televisions and electric vehicles at the Consumer Electronics Show (CES) in Las Vegas in January, there were a few start-ups claiming to have new ways of exploiting this ancient, and often overlooked source of clean drinking water. And with the help of artificial intelligence, they’re finding ways of pulling even more water out of the air.”
