Billboard Produces Drinking Water
Researchers at the University of Engineering and Technology (UTEC) in Lima, Peru, have collaborated with advertising agency Mayo Draftfcb to create a billboard that produces drinking water from humidity in the air.
The billboard, located in the village of Bujama, traps and condenses air to form water droplets, which are then filtered and stored in tanks. A tap at the base of the billboard allows residents to collect the water.
The billboard produces approximately 100 litres of water each day. It cost $1,200 to set up the internal system, which requires electricity to complete the filtration process.
According to Mayo Draftfcb, the billboard has produced 9,450 litres of water in three months – the equivalent water consumption of “hundreds of families per month”.
Water scarcity is becoming an increasingly crucial issue. For more on how forward-thinking companies are cutting and eliminating water usage, see Doing Without Water.
