April 28, 2015 (San Diego’s East County) - What if there was a way to extract water from the air—harvesting dew drops to help meet water needs?
Konstantin Avdienko, an 18-year-old student at the University of San Diego, has done just that. As part of the school’s annual Changemaker Challenge, he invented a “water condenser” using supplies readily available at hardware stores, 10 news reports.
The device uses a solar-powered fan to pull air through a PVC pipe into the ground, where copper wiring cools moisture in the air until it condenses into water, which is then collected in a container beneath the ground.
Avidienko got the idea while looking at condensation on a drinking glass. He says his simple device collects a third of a gallon of dew in just one day. He envisions condenser farms to help alleviate drought and assist poor communities in need of water.
