Lima, Peru, has the unfortunate distinction of being the second largest capital in the world located in a desert. It rarely rains there, and many of the residents are forced to get their water from dirty wells. But on the flipside, the humidity also hovers around 98 percent, so the local University of Engineering and Technology designed a clever billboard that’s able to harvest the moisture in the air and turn it into potable water.
The university teamed up with Mayo DraftFCB to create the billboard, because after all, who has more expertise with designing a giant sign than an ad agency?
A series of five tanks located at the top of the tower can store up to 96 litres of water at any given time, and the liquid reserves are accessible from a single faucet located at the base of the billboard. And because it’s being pulled directly from the air and further processed by a filtration system, the water is guaranteed to be clean enough for drinking all year round. [UTEC via PSFK]

“Hovers around 98%”
You mean 78% to 88%?
Come on, Gizmodo, you’ve been making so many dumb mistakes this week.
Did you not watch the video?
Try reading the articles out of interest not out of spite.
No — the video and source link both quote 98%.
When I was there the humidity was always around 80% during the day.. Although it was probably higher in the mornings when the haze came in from the ocean
So, why isn’t this technology being used to bring water to poor people of Lima other than through advertising billboards?
I’d guess it’s because the large surface area of the billboard allows it to collect more water and it being a billboard you could charge companies to advertise on it making the billboard pay for itself?
Because the advertising pays for it?
How much power does it use?
