Researchers at U.C. Berkeley and M.I.T. have engineered a solar-powered device that harvests water by extracting moisture from low-humidity air, thus offering an innovative way to operate low-cost, off-the-grid water delivery systems.
Experts believe the technology is a major breakthrough as it collects significant amount of water at relatively much low energy expense, writes Seeker. The water harvester, which currently extracts about a Coke can of water in an hour, can be scaled up to boost its capacity.
Moisture farming technologies have been around for some years now but the processes required either very humid air or involved impractically high electricity consumption, making them unfit for viable applications, notes Science.
