Engineers in Peru have invented a billboard that captures and filters moisture from the air, turning it into drinking water for any passers-by. The billboard is 50-feet tall and can produce 100 liters of water out of thin air every day. One billboard is capable of providing drinking water for hundreds of families per month. It was designed by Lima’s University of Engineering and Technology as an advertisement for enrollment. The billboard’s resourceful design takes advantage of atmospheric humidity to overcome the lack of transportable water in the coastal desert. Can you imagine these billboards in your city?
