The Inventor Trying to Suck Water From the World's Driest Air
.
" What started as the SunGlacier conceptual art project has evolved into the patent-pending Droppler technology, which uses solar power to pull water from the driest air — and could help some of the 5 billion people the United Nations projects will face water shortages by 2050." " It wasn’t until 2015 that he started constructing water-harvesting devices that put his art to the test, and it took years and more than 50 prototypes to get it right." "...the Netherlands Ministry of Defense invited Verheggen and his partners to run tests in Gao, Mali — one of the driest, hottest places on Earth, where temperatures can reach 122 degrees Fahrenheit with 3 percent relative humidity." " Even in desert conditions, van Geloven explains, a system that sucks in 50 cubic meters of air can yield up to 1,000 grams of water per hour. “It’s that simple,” Harrewijn says, noting that even his department’s researchers were surprised. The Ministry of Defense is providing financial support for the creation of a portable device aimed at generating up to 40 liters of water per day." https://www.ozy.com/rising-stars/the...c1fc106f66bb56 ------------------------------ ---------------- .
