UTEC, the university of engineering and technology in Lima, Peru in collaburation with Mayo DraftDCB has developed the world’s first billboard that can produce potable water from the air as a promotional admissions campaign. In this region rainfall is scarce year-round, but atmospheric humidity reaches almost 98% – the project provides residents with up-to 96 liters clean drinking water in reserve tanks situated in taps at the foot of the sign, instead of having them deal with polluted wells.
Interestingly, the project wasn’t so much driven by Lima’s need for water as UTEC’s need for more engineering students. Their motto is “We will continue changing the world through engineering.” And if this is what such students could get working on, we’re all for it.
The billboard contains five generators that churn out purified water through a reverse osmosis system. The system sends water to a tank that can store up to 100 liters per day. As you can see in the video above, people are actually using the billboard to get fresh water. In three months of operation, the billboard has produced thousands of liters.
Fortunately, the Peruvian government isn’t counting on UTEC and Mayo DraftCFB. They’ve recently announced a $3.3 billion-dollar upgrade they plan on making to their water and sewage infrastructure to provide better drinking water to their citizens.
