Lima Billboard Is Tapped For Drinking Water

PhysOrg

Pretty damn cool. ATS'rs living in humid climates may want to take notes for their local officials.

A billboard in Lima, Peru, created by ad agency Mayo DraftCFB in collaboration with the University of Engineering and Technology (UTEC), captures the air's humidity and turns it into potable water for Lima residents. Lima is referred to as a "desert megacity" where many residents cope with inadequate access to clean drinking water. The agency and university formed a team to produce what they refer to as the first billboard that produces drinking-water out of air.

Generators inside the billboard process the air and filter it into water, stored and drawn by residents at the bottom of the billboard. The system has an air filter, a condenser and a carbon filter. The system is designed to generate 96 liters of water per day for the local community. A video showing the project presents more of the details. "Each generator captures the air humidity," said a team member, "and from there it goes through a reverse osmosis system; each tank stores about 20 liters." Five generators' purified water is gathered into one tank.

That is pretty cool. It's not a question of can it be done, it's really always been a question of who is going to foot the bill.

Great idea, but how do they operate the generators. they don't mention it in the article or the video.

I'm guessing it's still cost effective. But it'd be something more if they were powered by stored energy from the sun.

A self sufficient water system, pulling energy from the sun during the day to extract moisture from the air at night.

In a humid desert environment that can only be win.

Artificial cactus with no need for roots or cell growth to take from the water.

it just seem common sense to me, but I am only thinking out aloud..

So cool

I wonder if it could be solar powered in the future -

I love this stuff :-)

edit to add: I need to learn to read the whole thread before I reply

What? Water from nothing??

I'm sure Pepsi/Coke will have something t say about that....


Great invention though. *+F for sharing

This is pretty awesome, they should mandate all of these eye sores around towns to use this style collection system. Not only would they be advertising, but they would also keep people from being thirsty.

Now if they would make these into giant towers dedicated to collecting water, it could help sustain a lot of local communities. This is what taxpayers should be funding, not endless wars and the encroaching police state.

In some areas the thing will pay for itself as the advertising costs quite a bit for a billboard. The water is available at the bottom so it would need to be off the highways.

Actually, they tried free water already, It didn't work.

Of course! because Coca-Cola said so!

Edit: My neighbor has one of these condensations machines and it does work.

Just think of it like this, your air conditioner drips condensation into a bucket (we have all seen these water filled buckets by the AC units) but instead of going straight into a bucket, it is actually filtered into drinking water.

Same deal...

Im sure solar powered generators an lithium ion batteries for night would be enough.

I like this idea so much, i started a hastily searched thread on it.

This is my opinion on it.

This, to me seems such a logical evolution of the Plastic sheet,

pinned with stones to collect condensation water in the desert.

If they are going to advertise anyway,

Why don't they do this all over the world?
