German conservationists Kai Tiedemann and Anne Lummerich came up with an ingenious solution to Peruvian village Bellavista's water problem. The small village south of the capital city of Lima has very little rainfall but a lot of fog, so the duo set up fog catchers to harvest hundreds of gallons of water a day right out of the air!
The nets stand perpendicular to the prevailing wind, which blows fog into the coarse, woven plastic mesh. From there, drops of fog-water fall into gutters that carry the water to collection tanks.
