Billboard in Peru Turns Air into Clean Drinking Water

Just outside Lima, Peru, a billboard provides drinking water to whomever needs it - producing water out of thin air for residents of the desert city.

The world has known jugs, taps, plants etc that are used to filter water, but imagine a 50 feet tall billboard on the main road that filters water for all of its adjacent area ? Yes, this has been made possible by the University of Engineering and Technology, Lima, Peru.

This billboard is capable of actually making 100 liters (26 gallons) of water everyday out of thin air (no its not a bank and no its not creating any paper currency but it’s much better than that). It works like this: the billboard is designed the way that it captures moisture from the air and puts it through a reverse osmosis system, turning it into drinking water which is then stored in 20 liter tanks. It is capable of providing drinking water for hundreds of families per month.

Originally it was designed by Lima’s University of Engineering and Technology as an advertisement for enrollment  the billboard works to overcome the lack of transportable water in the coastal desert. The resourceful design takes advantage of the atmospheric humidity of almost 98%, to counter the dangerously low annual rainfall (just over half an inch).

We all know that the government will not fund this but could this be the answer for other drought-stricken cities around the world? Can this be used in the deserts of Africa where many people die either because of the non-availability of water or because of the water born diseases? Can this method be used in cities and cosmopolitans where most of the tap water is fluoridated which is not only bad for health but also a reason for many diseases such as cancer.
