Over seven million people live around the Atacama Desert in Lima, Peru, and more than a million have limited or no access to clean drinking or bathing water. So when the University of Engineering and Technology decided to unveil a billboard that can generate water out of thin air, it wasn’t just a novelty. It was a very real life saver.
The billboard was erected last December as a way to boost UTEC’s sagging attendance numbers. It works through five condensers inside the billboard, which collect and extract moisture from the region’s as-high-as 90 percent humidity and converts it into clean water. This water can then be reached through spigots located directly underneath the billboard.
