Lima, Peru is the second largest desert capital in the world, with almost 8.5 million residents. The arid city’s average rainfall is a mere .51 inches per year, but the humidity is around 98%. So, how do you tackle water scarcity in such an environment? The University of Engineering and Technology (UTEC) answered by creating a billboard.
The billboard is engineered to capture the extremely humid air and turn it into purified water for the community to use. The air goes through air filters, then a series of condensers and carbon filters to liquefy and purify the H2O. The water is then collected in a central tank, where members of the community can come to fill up. Access to clean water is a crucial aspect of communities that most of us take for granted. UTEC managed to give themselves a good name, advertise themselves, and make a huge difference in a community all at once. As humanitarian efforts continue to garner attention, campaigns such as these will become increasingly common.
