Peruvian Billboard Turns Humidity into Drinking Water

The University of Engineering and Technology in Lima, Peru has invented an incredible new billboard that sucks humidity from the air and turns it into drinking water for local residents. Clean drinking water can be difficult to come by in Lima, as the city rests on a desert where it rarely rains, and many of the city’s wells are polluted. However, with 98% atmospheric humidity, engineers saw a tremendous opportunity.


The billboard’s generators capture water vapor and, using reverse-osmosis, transform it into potable water that is stored in tanks. Residents collect the water from taps on the billboard and furnish their supplies of clean H2O.

The billboard has produced 9,450 litres of water in 3 months, which equals clean water for hundreds of families.

      Agreed. Suddenly billboards don’t seem so annoying.

    Ahhh! This is so cool!! I guess here is an example for how science and innovation can solve the world’s problems (at least some of them). So basically, if you have a brain, use it! Collaborate, with people to turn ideas into realities!

      Exactly! Progressive innovation and collaboration –especially innovation that helps needy or marginalized groups of people– is what we need to see.

    Sounds great – is it affordable though, or is it more of a one-off? Either way, an inspiring story 🙂
