Billboard in Lima Produces Potable Water

Lima’s University of Engineering and Technology (UTEC) and the ad agency Mayo DraftFCB have developed a billboard that convert’s the Peruvian capital’s moist air into potable drinking water.

Lima is situated in a desert where annual rains amount to just over half an inch, or 1.5 centimeters, a year. There’s lots of humidity in the region however, hovering at about 98 percent, which can be collected.

This is apparently an offshoot of a previous project in which giant nets dubbed fogcatchers are used to trap water from the area’s humidity. National Geographic had a good summary of one such project here.
