Now drinking water can be extracted from air
The University of Engineering and Technology of Peru (UTEC) has designed the first advertising billboard that produces around 100 litres of water a day, from the humidity existed in the air. UTEC is located in Lima, the central desert of Peru, which is certified as the second largest desert capital of the world after Cairo, Egypt. The city is situated along with the southern Pacific Ocean but one part of it lies at the northern edge of the Atacama, the driest desert in the world.
According to a 2012 UN report, 783 million people (that is nearly 1 in 9 people) across the globe do not have access to clean drinking water. More than 3.4 million people succumb to death due to disease generated by water, poor sanitation and lack of hygiene.
Lima sees virtually no rainfall but has high atmospheric humidity. It is said that the air of Lima contains 83% of moisture and the people of this wet dessert suffer from a huge deficiency of potable water.
FCB Mayo, an ad agency, came with the primary idea of extraction of water from air, mainly from the humidity existing in the air and approached UTEC to work on the project. With the small amount allotted for the cause, the University of Engineering and Technology of Peru (UTEC) started working on the innovative project of extracting water from air.
FCB Mayo and BPN Peru are the advertising partners in the project with UTEC. Some 9,450 litres of water has been produced by the billboard within three months. And it is estimated that the billboard will help hundreds of families suffering from shortage of drinking water.
The technology is not completely self-sufficient. It requires a generator to power the five devices of the billboard which work on the filtration process and each device generates up to 20 litres. The water finally transported through small channels to the central tank, designed at the billboard’s base.
Talking about the innovative technology to create water from air, Alejandro Aponte, the creative director of FCB Mayo said in an interview that they wanted to inspire engineers to introduce new technologies; technologies that address the basic problems of society and its need.
