In Peru, Clear Channel has launched the world's first ever billboard to create drinking water from humidity in the air. The billboard is the product of a partnership between the outdoor advertising owner, the University of Engineering and Technology (UTEC) in Lima, media agency BNP and advertising agency, Mayo Publicidad.
It sits above the skyline in Bujama, a small village community just south of Lima where some residents have no access to a clean water supply. The climate is humid, so the billboard uses a panel to trap humidity in the air. This extracts water vapor that's stored in tanks at the top, then the water is filtered before flowing down a pipe to a tap. Since the billboard's arrival at the end of last year, Clear Channel says residents of Bujama now have access to an average of 96 litres of drinking water a day.
