This Wind-Powered Device Pulls 11 Gallons Of Drinkable Water From The Air Each Day

Whereas many individuals in developed nations often worry over catching their favorite television show, a constant stress for approximately 2.3 million people on the planet has to do with obtaining clean, drinking water. Fortunately, a solution to the latter conundrum has been presented, and it's one that might ease generations of worry in locations where purified water is hard to come by.

The Water Seer collection device relies on simple condensation to collect drinkable water from the atmosphere and can provide up to 11 gallons of clean aqua without one external power source each day. Best of all, it can potentially run forever and does not create greenhouse gas emissions which contribute to climate change.

To ensure the device works, it's planted six or more feet into the ground, then soil is packed around its metal neck. Inhabitat relays that the device holds a vertical wind turbine in which internal fan blades spin and draw in air into the subterranean chamber. Because the underground portion of the invention is cooled by the surrounding earth, water in the air drawn in by the turbine condenses and is collected in a sort of artificial reservoir. It's from this well that people can draw clean, safe drinking water 24/7.

VICI-Labs is responsible for creating the game-changing device in collaboration with UC Berkely and the National Peace Corps Association. It didn't take long for the IndieGoGo campaign to raise over $77,000. Apparently, many people are interested in seeing "orchards" of water collection devices in communities around the world.

Every 90 seconds a child dies due to lack of clean water. Over 2.2 billion people don't have access to safe water.

Great! Just install 500 million of these worldwide and that problem'll be solved.

Who'll pay for it? Pepsi or Coke if either installs a billion of these babies, bottling the excess to sell under some new brand label. If people are gullible enough to pay for water supposedly from Mt Fuji where only the enterprise profits, then they'll be more than happy to drink water sourced from beneath Africa et al. benefiting its underprivileged inhabitants directly/indirectly.

PS: Rich astronauts drink their own piss. Hey, maybe we could bottle that and sell it to them flat-Earthers.

A version that uses a sterling engine instead of a wind turbine might actually be practical.

I was thinking, "This is game changing," and then it mentioned the same thing towards the end of the article. 

But yes, things like this and renewable energy would make the world much better.

I doubt. Smaller Stirling engines have a efficiency factor of 0.1or less which is terrible.
And in bigger size they are getting very expensive.
Not something you want to sell to the 3rd world population.

The previous game changer on Kickstarter that produced more gallons of water per day:

We wrote about the towers last year when Vittori unveiled a full-size prototype. The company has a newer version of the WarkaWater and a Kickstarter campaign to fund field testing in Ethiopia later this year. Based on tests performed in its Italian lab, the company claims the latest iteration can harvest 13 to 26.4 gallons of water daily. That’s less than most people flush away each day, but a significant quantity in a country where some 60 million people lack sufficient potable water.

It seems to cost 1000 $ though in relation to the 180$ from OP.

Btw. I really support stuff like that. In the future drink water will be one of the most valuable resource for us humans.

The efficiency of wind on a hot day with no wind is zero.

Well if your energy source is wind and you have no wind....

I guess you wanted to use a sterling motor with gasoline? ^^

Btw. Do you understand what the youtuber did there?

We're discussing the use of the temperature differential between the Earth and the air & surface to not only to condense the water vapor into a liquid but also to power the device on days with no wind. The argument that my solution was too inefficient to work was countered by a simple demonstration of an inexpensive sterling engine powered by some ice water.

That is exactly the point.
In your case you need additional energy to create and maintain the ice. But this is exactly not wanted. No additional energy source needed.

The stirling engine works like a heat pump so a greater temperature difference is more effective but that becomes harder to archieve if you have more then a cola can to cool down especially in 3rd world countries with unreliable electricity.
