Alex,

Start a new thread in the cider press.  Maybe quote from some bits here to get your new thread started.

Bill mentioneed wildlife guzzlers which are comon in our area as well. The majority of the collection being from rain and snow, however those made with metal roofing do scavenge dew as well. several diffrent styles and configurations. some collect the water under the panel in an enclosed vessel and the trough component has a float valve to draw water from the reservoir as the trough empties, preventing  some evaporation.

Cassie said "At its simpliest an air well is a structure or a device that collects water from the air using condensation



I am a firm believer that rocks are one of the best examples of this and this is why air wells work.

What are some other ways to collect water from the air?

What about water vapor collection and fog collection:

https://en.wikipedia.org/wiki/Fog_collection

Since this thread is about Air Wells has anyone seen water collecting Air Wells?  Where are these air wells?

Do Air Wells really work?

How do those guzzlers work, I live in a dry forest and I have big bird drinkers, but out in the forest more could be used.
How are the fed?
Do they evaporate dry?

John, some are fed by rain and snow, some in our area are adopted by a local that drives out and fills their adopted guzzler.  Many different designs and degrees of how much they collect.

Source Global makes the water harvester that they are using in Warm Springs for potable water. Guzzlers here are not a purchased piece of kit but creatively crafted.

Maybe we should split from "air wells" to water harvesting?

Seems like most of the stuff I'm finding is saying mediums with high thermal mass are not ideal ... they retain too much heat (overnight?).

Heat is part of the process:

...we harvest water by combining atmospheric humidity, heat and air flow...

It is possible to harvest water from air almost anywhere in the world. Our core Air-to-Water unit uses a turbine that forces air through a heat exchanger, where the air is cooled and condensation takes place.



https://rainmakerww.com/technology-air-to-water/

[Many atmospheric water generators operate in a manner very similar to that of a dehumidifier: air is moved over a cooled coil, causing water to condense. The rate of water production depends on the ambient temperature, humidity, the volume of air passing over the coil, and the machine's capacity to cool the coil. These systems decrease air temperature, which in turn reduces the air's capacity to carry water vapor.

https://en.wikipedia.org/wiki/Atmospheric_water_generator


These technologies are given only as an example regarding the statement about the heat.

Air Wells, of course, do not use this technology, though it is the same heat process as the cool air is what produces the water.

I would imagine that there are times when it is just too hot for them the air wells work.

Does anyone know how those Source Global water collectors manage to keep from being filled with dust and getting all gummed up?  

Source Global hydropanels how they work (but doesn't seem to explain how dust and sand are filtered out...)


The company is in AZ, so I guess they figured something out... but I can't fathom what!  ha  I'm also in the desert, and you should see my window sills... it's a constant effort to get the sand out.  After a sandstorm or dust storm, there is dust/sand on everything indoors and out.

Thanks for the links above to more low-tech options, too!
