Well. Its certainly humid here.
How does it work?
Just consider how many times a day ya have to empty a small dehumidifier in your home down there....... Now figure you can make 5 gallons a day for drinking and expand upon that concept.
We made one from a store bought dehumidifier, macgyvered up some under sink water filters and made 4 gallons in a day up here.
Willie Inc has residential and commercial versions that make much more a day.
