A Billboard that Produces Clean Drinking Water from the Air
A Peruvian university worked with designers to create the world's first billboard with a tap: the billboard shows off some of the university's technology for making clean drinking water from humidity in the air. Lima's in a desert (though the air is humid), and water that residents draw from wells is often polluted. Interesting technology, and an interesting way to make a billboard better tell a story, and serve an actual need.
