Water from air

This process has been used for 1000's of years  and consists of a variety of techniques, capturing fog, drawing humidity out of the air.
They work.

This is another system, the presentation is long winded, and its sold like a 'steak knife set' but it has elements of truth in it.
Some have called it a scam, I dont know, perhaps form your own opinion and comment .

Hi John.  I looked for it too and found no one that is actually using it.  I would think with millions of acres left unplanted, because of drought this year this design would be all over the world.  I would love it if it were true.  Some things that make me wonder are no maintenance, 20 gal a day and all the other warning stuff around it.  Hopefully someone else will see your post.

Everything about this flies in the face of common sense.  You can build a device for $200 that will supply 20 gals of clean water a day from air.  So why does every family in the world not have one?  People are walking miles a day to get any amount of drinking water all over the world.  If this worked, there would be groups all over the world building them for people living in third world nations where people are dying from lack of access to clean water.  20 gals a day would supply all the water a family needed.  Maybe someday someone will come up with something like this, but I don't believe the day is here and you can build one with hardware store supplies and never have to touch it again.  Color me skeptical.  

While I don't know what is at that link it seems to me that the concept is not new to permaculture,

I have been reading for several years about "air wells" and "fog harvesting".

Anyone interested in the concept will enjoy these:

I put this item up because as Anne has said, its not impossible, its being done in a variety of ways.
In Australia I have seen 'dew collection' systems.
But I found this and whilst I have yet to study the websites credentials I have listed it so others can decide.

Looks like a standard electric dehumidifier that the user hooks up to a small water pump & water filter. No big mystery. I think the 20 gallon per day number is highly optimistic for a standard room dehumidifier. I had one of those in central Texas & it produced about a gallon per day.

A couple other things I noticed from your linked site.  That site says 60 gals a day.  It also says "The system works by drawing in humid air and compressing or condensing it to a level where the water collates. The Water Freedom System, therefore, will guide you to build the condensation device."  It sounds like he is talking about building a very large dehumidifier.  But then he goes on to say that you will need to come up with a list of things including:
A new dehumidifier
One cabin air filter
A water filter dispenser
A submersible water pump
Clear vinyl tubing of different sizes

These are the main components of the machine, according to the site:
A 55-gallon plastic barrel drum and lid
Another plastic lid that will fit inside the barrel
A round piece of plywood

He goes on to tell a little more about the building process.  In essence, it sounds like he is using a 55 gallons drum to contain a large dehumidifier and then filtering the water it pulls from the air.  There isn't really anything wrong with that, except that to get 60 gals a day would be impossible with only one of these, so you will need more than one.

This is from a dehumidifier site.  "Whole-House Dehumidifiers are large; thus, the amount of water vapor extracted is much more than that extracted by room or portable dehumidifiers.  Consequently, the amount that accumulates in the water collection bucket is more as you use larger units. Meanwhile, most room dehumidifiers can only remove around 40 to 50 pints of moisture per day from an average room around 2,000 square feet. " as well as

"With the exception of desiccant dehumidifiers, the ability of the dehumidifier to collect water depends on its power, temperature, and relative humidity level. The majority of machines can extract around 2 to 5 gallons of water per day. However, with larger dehumidifiers, you can collect up to 13 gallons at 85% relative humidity and around 86° F."

I can't imagine the electricity costs to run one that would provide 60 gals a day.

It would be great if there were more details given, of if someone had built one of these and posted it on youtube or something.  I can't find a single actual review of the material, only dozens of sites selling it.
