Gallery: Billboard Produces Drinkable Water From Desert Air in Peru


Peruvian researchers have collaborated with an ad agency to create an unusual billboard that generates drinking water from thin air. While the billboard fulfills its traditional role as an advertising tool—in this case for courses at Lima’s University of Engineering and Technology (UTEC)—it harvests moisture directly from the air, which is then processed through a filtration system. Capable of producing 25 gallons (96 liters) of water a day during summer, the billboard has produced 9450 liters of clean drinking water for a nearby community in the three months since it was first installed.

Lima, Peru’s capital city, receives less than one inch of rain each year, forcing some residents to get their water from dirty wells. Despite the lack of rain, the high humidity makes it possible to harvest water directly from the city’s air, providing a sustainable, alternative source of drinkable water.

The researchers at Peru’s University of Engineering and Technology teamed up with Mayo DraftFCB advertising agency to create the billboard. The panel consists of five machines which convert humidity into water through use of air and carbon filters and a condenser. The water is stored in five tanks located at the top of the structure. The filtered water flows into a pipe at the bottom of the billboard, supplying the neighboring community with clean water. In the three months since it was first installed, the billboard has produced 9450 liters of water.

    This is brilliant and obviously could have a massive impact all around the world in these types of climates if the idea catches on.

    It is a completely false statement that we are running out of drinkable water. We are simply not utilizing it sustainably, consuming it faster than it can replenish itself which happens naturally and will long after we are gone, given time.
