Hello all. So I am trying to see if it is possible to build a device that is able to extract water from the surrounding air. I know there are a couple of systems that already do that (based on condensation), some active and some passive, such as the atmospheric water generator (this device is tooooo expensive though) and air wells. As little as 50mL of water per day will do (more will be better). I read somewhere that a dehumidifier can be used to extract water from air (but that can cost around $200), worst comes to worst, i might have to go with this method. I also read how air well's work, but cannot come up with a decent method. Can anyone provide me with a link or method that may be able to help achieve what is needed (assuming my goal is achievable)? Primitive methods are okay as long as the system is somewhat portable.
