Dehumidifiers already exist. You can get one at Walmart for 30 bucks.
Ya I realize that, and certainly it is using cooled condensers some way. (With a filtering system)
What intrigued me was that they said it's cheaper than ground water treatment or de-desalinization. It's also mobile and capable of being implemented in specific or remote areas and could be ran even with loss of power in the surrounding community.
If I had the money, I'd be buyin one!
Unfortunately, there's not enough water in the air to provide enough water for even one person. The only places where such technology would yield even a modicum of water are high in humidity, and places with high humidity are like that because they have steady and regular rainfall. In which case, it would be much cheaper and easier to just collect the rainwater in barrels.
Ah yes, rain. That would make things easier. Although not as consistent supply.
But, I'm gonna have to disagree with you on the amount of water available in the air. Here is a page that goes into great detail about how much water is in the atmosphere.
-"On average, there is about the equivalent of 30 mm [1.2 inches] of rain in the form of vapor available to fall over any point of Earth's surface," -"That's around 55 pounds [25 kilograms] of water over every square yard, most of which is in the form of vapor,"
Also, anybody that has ran a small dehumidifier in their basement will tell you how fast you fill it up. Easily 10-25 gallons a day, depending.
I just realized I need a dehumidifier that will run on DC current.
