article imageBillboard creates drinkable water 'out of thin air'

Lima - A billboard in Peru has been making headlines for creating water from humidity in the air. Media reports say it produces over two dozen gallons of water a day.
Marketing can be found in many aspects of life. One billboard in Peru has not only promoted a message, but also gives what could be a partial solution for the desert region. The billboard literally creates drinkable water "out of thin air", reported TIME.
Located in Lima, the billboard is a joint effort between The University of Engineering and Technology of Peru and Mayo DraftFCBand, an ad agency. The school is looking to recruit students and the ad agency was "struck on the idea" of a billboard that could create potable water, according to the TIME report.
“We wanted future students to see how engineers can also solve social needs in daily basis kinds of situations,” said Alejandro Aponte, creative director at Mayo DraftFCB.
Lima is one of the driest desert regions in the world, second only behind Cairo, but has extremely high humidity. It receives a minimal amount of rain, less than 1 - 2 inches per year, according to media reports. Residents are often forced to take polluted water from wells, according to the Huffington Post.
How it works is through reverse osmosis, a water purifying process and then the water is placed into storage tanks at the billboard's base; water comes out of a faucet. TIME reported the billboard creates approximately 26 gallons (100 liters) of water a day.
How much electricity it uses is not clear, but it has produced 2,500 gallons (9,450 liters) of water in the past three months and appears to be widely viewed as a potential and/or partial solution to the region's water problems for an area where lack of clean water is a serious issue.
A video was released last month that further explains the billboard project:
Phys Org reported the Ministry of Housing says approximately 700,000 Lima residents lack access to drinkable water, and another "600,000 rely only on water cisterns." The country is about to invest $3.3 billion in Lima's water and sewage infrastructure to improve availability and quality of water.
