Titre : In desert trials, next-generation water harvester delivers fresh water from air

ScienceDaily (June 8, 2018)

Résumé
Scientists who last year built a prototype harvester to extract water from the air using only the power of the sun have scaled up the device to see how much water they can capture in arid conditions in Arizona. Using a kilogram of MOF (metal-organic framework), they were able to capture about 7 ounces of water from low-humidity air each 24-hour day/night cycle. A new and cheaper MOF could double that.

Présentation
Last October, a University of California, Berkeley, team headed down to the Arizona desert, plopped their newest prototype water harvester into the backyard of a tract home and started sucking water out of the air without any power other than sunlight. The successful field test of their larger, next-generation harvester proved what the team had predicted earlier in 2017 : that the water harvester can extract drinkable water every day/night cycle at very low humidity and at low cost, making it ideal for people living in arid, water-starved areas of the world.
