This Billboard That Produces Clean Water

In 2013, it seems advertising is needed about as much as clean water. So it's refreshing to see one company work to combine the two. Located in Luma, Peru, and developed by The University of Engineering and Technology of Peru (UTEC) and ad agency Mayo DraftFCB, the billboard is able to produce around 26 gallons of water a day using five filtration devices and Lima's extremely humid air. The billboard is designed to not only provide water to Peru's largest city-one in which 1.2 million residents don't have running water, but to also encourage kids to apply to the UTEC and study engineering.
