Billboard turns air into free drinking water

An advertising billboard in Peru produces clean drinking water from the humidity in the air.

Engineers from the University of Engineering and Technology in Lima teamed up with an advertising agency to produce the sign which provides clean water to people in the local vicinity who often struggle with supplies due to tough conditions and very little rain. To date the billboard has produced more than 9,000 litres of water, a rate of 96 litres per day.

"The panel traps humidity in the air and transforms it into water. It's that simple," said university spokesperson Jessica Ruas. "We want to change the minds of future engineers and inspire them."

"Just outside Lima, Peru, a billboard provides drinking water to whomever needs it - mainly, its neighbours."

This is, of course, a wonderful and inspiring story BUT ....... in the 21st century is it not appalling that a country that has had billions thrown at it, has left it's citizens in such poverty and ignorance? It is appalling regardless of what century we are in, too much of 'mans' suffering is caused by other men and its inescapable... Great article though, thanks for posting Seeder. Ties in with your avatar nicely to.

Of course it wouldn't work in AZ. I'm wondering about smog. Wouldn't toxins get into the water or at least a bad taste? Of course it would work in AZ, the water is run through filters to remove airborne impurities.This is pretty cool actually, it's how the frement got much of thier water in Dune.

This probably only works in desert areas bordered by a cold sea current. You need fog and something for it to condense upon. I believe there are fog traps like this in Namibia and in other similar areas, though much simpler in construction than this billboard, basically just mesh with a gutter system at the bottom to collect the moisture. There are cacti in western costal South America whose spines do the same thing. Water collects on them and trickles down to stems to the root system, which allows them to thrive in a land with no (or almost no) rain. Reminds one of the planet Arrakis and the ... [More]

I think this is a great idea, genius whilst simplistic. I agree it won't work everywhere, but somewhere is better than nowhere.

Cool! it wouldn't have to be a billboard... this system could be made on fences for instance. Water condensed form the air would be 'distilled' water... pure .. but lacking in any minerals .
