Clear Channel Billboard Creates Water From Peru HumidityLouise Downing
A billboard is extracting enough drinking water out of humid air to help supply a Peruvian village near Lima with about 96 liters (25 gallons) a day, Clear Channel Outdoor Holdings Inc. said.
The San Antonio-based company that operates 750,000 outdoor advertising displays on five continents said today in a statement that the experimental $32,600 billboard in Bujama, south of the capital, dispenses enough clean water that 15 to 18 family villagers access the filtered liquid daily.
The water is used by villagers for cooking and drinking as it doesn’t need to be boiled, according to a Clear Channel video. One resident called it water “from heaven because it comes from air.” Schoolchildren stop to drink from a tap at the billboard, including those from running classes.
The billboard uses a panel to trap humidity in the air. The panel comprises five devices that extract water vapor that’s stored in tanks at the top. The water is filtered before flowing down a pipe to a tap available to anyone who passes.
About 15,000 liters of water have been produced in the six months since the billboard was installed, according to the statement. Clear Channel said it developed the project with researchers at the University of Engineering and Technology in Lima as well as a media and advertising agency.
