Video of DIY Atmospheric Water Generators

November 29, 2019

Atmospheric Water Generators are machines that work on the same principle as dehumidifiers. They produce water from atmospheric moisture. The difference between them and the dehumidifiers is that the water they produce should be safe to drink.

In this video from desertsun 02’s channel on YouTube, a man shows off a simple AWG that’s he’s built himself. The explanatory paragraph for it runs

DIY Atmospheric Water Generator. Unit pulls Pure ‘distilled water’ straight out of the air! works best in hot humid conditions. this simple design pumps near freezing water thru a long section of copper coil. coil becomes very cold and dew (condensate) forms on the coil. the dew is then caught by a drip-pan located beneath the coil. *note that this unit has the added benefit of dehumidifying the air. *an AWG is essentially just a “Food Safe” dehumidifier. (my previous video shows this unit being operated primarily as a dehumidifier… the difference being that that design has plastic parts that come in contact with the water). to keep the water as ‘pure’ as possible, i used only aluminum and copper in this version. main thing with these is to keep the coils clean. if coils are cleaned after each use, the water generated is ‘distilled water’.

Of course, it raises the question that if he’s using cold water to condense the water in the atmosphere, why doesn’t he simply drink the water rather than go to all the bother of cooling and pumping it around just to get a few ounces from the atmosphere. But it’s a brilliant piece of home engineering, and scientists and engineers are building machines like these to give people in deprived, parched areas potable water. And we may need more of these machines very soon if the planet continues to warm up and desertification increases.

Texas Man Invents Machine that Creates Drinking Water from Air

November 25, 2019

This is pure Dune technology. This short video of just over 2 minutes long from RepsUp 100 channel on YouTube is a news report about a former ranger, Moses West, from Texas, who has invented a device that creates drinking water from the air. He invented his Atmospheric Water Generator back in 2015. West says of his machine that they’re at the point where they can talk about creating 50,000 – 1,000,000 gallons of water. The energy consumption is incredibly low. According to West, it’s far cheaper than groundwater and desalination. He has so far made eight of these machines. They’re in the Bahamas, Puerto Rico and Flint, Michigan.

According to West, the machines are federally approved and the water quality is tested by the Colorado Water Authority. Most of West’s devices were manufactured in Manitowoc, Wisconsin. The news broadcast says that the townspeople should be proud, as one unit provides the town with hundreds of gallons of clean water. It also appears that it doesn’t cost the residents anything, as West works with organisations like the Water Rescue Foundation to cover costs. He also says that people were very happy that somebody actually cared enough to jump over the bureaucracy and do this on a private piece of land. His concern now is to plant these in Flint, Michigan, to help the people there.

I don’t think West’s idea is particularly new. It seems to be a variant on the domestic dehumidifiers that are used to clean the moisture out of people’s homes. Some of these, like the one in the video below from Unbox Therapy on YouTube, manufactured by Ecoloblue, create drinking water from the moisture collected. West seems to have just created a larger, industrial scale version.

It’s a great device, and West is right when he says that there’s a water crisis coming. Back in the 1990s the Financial Times ran an article about how climate change and increasing demands for water are creating conflict. It predicted that in the 21st Century, most wars would be over water. When I was studying for my archaeology Ph.D., I also went to a seminar by a visiting professor, who had researched the effect climate change had through the human past on civilisation. He too was concerned about a coming water shortage. Machines like this could help solve some of those problems.

However, the use of these machines also demonstrates glaring iniquities in the American water supply system. Flint, Michigan, became notorious a few years ago because the local council had allowed companies to pollute the town’s drinking water to truly disgusting levels. People in a superpower like America, the world’s richest country, should not have to rely on charities for their drinking water.

It is, however, very much like something from Science Fiction. I’m reminded of the technology in books and films like Dune and Star Wars to bring water to the desert planets there. Like the system of underground cisterns and windcatchers in Dune to irrigate Arakis, and the moisture vaporators on Tattooine.

Now if only someone would invent something else from Dune – the stillsuit. A suit that collects water from the wearer’s own sweat and urine, and purifies it, turning it into drinking water so that they can survive weeks, even in the deepest desert. And in the 1980s David Lynch film, looked really cool too.

Here’s a brief video from Dune Codex on YouTube explaining how these fictional suits work.
