It's been a year and by now, you might have read about University of Engineering and Technology in Peru researchers' innovative way of combining marketing with true engineering genius in their Lima-based billboard that pulls water from thin air.
Peru has always suffered from a lack of moisture, making it at risk for drought conditions. But its water conditions have worsened. As this article from Time states:
"Because it sits along the southern Pacific Ocean, the humidity in the city averages 83% (it’s actually closer to 100% in the mornings). But Lima is also part of what’s called a coastal desert: It lies at the northern edge of the Atacama, the driest desert in the world, meaning the city sees perhaps half an inch of precipitation annually (Lima is the second largest desert city in the world after Cairo)."
The city relies on water that trickles down from the Andes, specifically glacier water. However, with the effects of global warming, this water source evaporates faster and faster as years go by, eroding the supply for the fifth-largest city in the Americas.
