Military has full scale Atmospheric Water generators, if you want to spend thousands.
I have actually toyed with the idea of using a dehumidifier as a low tech, redneck water generator-- biggest issue is the large amount of power they take. The whole point of plug in dehumidifier is to pull water from the air.
k, NOW I am going to spend the next half hour looking for 12 volt RV dehumidifiers to see if this could be done via solar?
I wonder if you could ""supplement"" the humidity using local plants..
