Is this a possible Water Prep Long Term Solution? - Creates Water from Thin Air!
"This GENNY Home Unit Creates Drinking Water From The Air"
https://www.forbes.com/sites/jeffkar...h=11ce37373619 "The solar version can pull in up to 3.5 gallons a day and is ideally suited to remote locations. It will sell for $5,000-$8,000 depending on location and configuration, starting in the third quarter, Harris says." https://us.watergen.com/ "About drinking water from air" "The production of drinking water from humidity in the air (AWG) is one of the most important and innovative water extraction solutions available today, used to tackle the growing problem of depleting levels of drinking water in the world. Within a decade from now, it is believed that 50% of the world's population will live in areas without access to clean, fresh, and safe drinking water." Not sure if this is currently available for sale in USA, but if so, would this be a good prep for a long term water solution?

This has been brought up in the forum before, try searching for it. However, the general consensus was no, it is not economical because of the amount of electricity required to refrigerate the collector, allow the moisture in the air to condense on it, collect and then treat it, usually with UV. To create enough for regular household use would require a rather large unit so it does not scale well. Living in a dessert with dry air, only reduces the efficiency as well.

Perhaps as hydrogen-fueled electrical cells proliferate and become more affordable, the water by-product of the process will create another benefit layer. Remote locations usually need power of some sort and wind and solar vary with nature which is why many people rely on generators as part of their power scheme.
In a damp environment, condensing moisture from the air works pretty well, I've played with it at my OR place where the humidity usually is in the 70-80% range and temps are under 70 max, using a typical window AC operating in open air. If the space is enclosed, the unit will dehumidify the air and loses effectiveness. Power is pretty cheap, 7 cents kwh but without capturing the waste heat/cold air, the unit is pretty inefficient. I guess as long as the well pump works and the creek keeps running, capturing moisture from the air is something I'll leave to the redwoods and firs and cedars on the place. They do a pretty good job, some days creating their own rain. |

Its basically a really expensive Dehumidifier with more filtration. So the real question is would you like to "purified" grey water that is not only cost prohibitive but also may get you sick if 1 part of the multi-filtration system is not adequate?

Or you could just cover the California Canals with solar panels for a win-win 3rd world solution.

Solar powered a option?

Have been doing this in African regions for years. Small village type setting
Like fueling the cooking fire with methane generated by a sealed composter full of animal dung. |

I guess there's a plug in version and another that runs on solar?
https://www.forbes.com/sites/jeffkar...h=7f8e5b843619 "Gather ‘round the water cooler and take a sip of this: Watergen plans to start selling a consumer version of its “water from air” appliance later this year. Dubbed the GENNY, it can generate up to 8 gallons of drinking water per day. There’s a plug-in version and another that runs on solar power."

There was a crowd source funding for a similar project that was BUSTED as fraud.
This is a very close match. The issue- 1-lead in the dehumidifier makes the water unsafe to drink. The unit was made as a dehumidifier... 2- power - cant get 10 amps from the solar 3- relative humidity- if its dry - no water is made to me - Forbes is now a pay to play advertisement- no longer a real publication

IIRC, it was called an "Air Still". Nothing to it really. But reserved for emergency only status.
Dig a hole in sunny spot little smaller dia. than the plastic rain poncho we all had. Deeper is better, traps more air, but no need to go crazy. Place pan from cooking kit centered in bottom. Place small rock in middle of poncho as weight. Spread poncho over hole. But not "tight". Leave slack so rock is well below ground level. Place rocks and dirt on poncho around all edges. To trap the air underneath. During daylight it is a small solar oven. Heating the soil in hole and cooking the moisture out of soil but trapped under poncho. Sun goes down, temp drops, Doesn't take much temp differential for the really humid air under poncho to give up the moisture. Condensed moisture collects on underside of poncho. Which runs down to low spot created by the rock weight on top. Drips into pan. Of course the more humid the atmosphere, and moister the soil the more it produces. Big Horn Scout Camp at Lake Arrowhead. You can get 6 to 8 oz a day. |

You NEED to get out of the bay area more, or watch some survival videos... at least SOME (on Discovery?)...
Youtube: "solar still". Quote:
"Solar Still" is the name I have heard used on multiple occasions. You can even do this with leaves if liquid is unavailable for lesser results. |

I remember being told to add leaves/cactus to increase water quantity.

Anybody have thoughts on this item? Yes, it may be a bit expensive, but in regards to how it operates/functionality would it be a good emergency water distiller/option?

Desalination using the Sun
http://youtu.be/hdmCqtIpFOc Rear projection TV fresnel lenses, parabolic mirrors, many adjustments needed for the Sun's movement, but boiling 5 gallons of water with his still made out of an old propane cannister. His channel is pretty cool. He shows how to DIY all of these, including the parabolic mirrors out of a trashcan lid and emergency foil/mylar heat blankets. On a sidenote, wouldn't a large dehumidifier and a Berkey filter do the same job but much less expensively? Last edited by surfdesigner; 07-29-2021 at 9:16 AM.. |

Solar stills and drinking urine are for emergency survival, not a permanent solution for long-term survival if potable water supplies run out or get contaminated. I certainly don't consider drinking urine as being "prepped".
For $5000-$8000, one could build & bury a concrete water cistern that holds anywhere from 500-10,000 gallons of clean & cool water, and have plenty left over for a pump, rainwater collection system, along with sand & gravel mechanical filtration & charcoal chemical filter. Should still have enough for truck delivered water to fill it.
