On the desert planet of Tatooine, where Luke's uncle was a moisture farmer, it got me to thinking about building my own moisture collector.
Power: Of course, it would need a power supply, either wind or solar, and a battery system to run the unit longer, but not necessary. Easy enough to buy off the shelf systems, especially solar. The wind turbine might require more thought.
Moisture Collector: Dehumidifier can be bought fairly cheap which is basically a moisture farmer. The water can be directed into a collector device with a Berkely osmosis water filtration system, then to a clean water area for storage.
I'll do further research into how they work, and possibly tinker with my own version. The more mechanical the system the better. Most of my preparations have been geared towards a long term grid down situation or EMP event.
Here is a link to a version already on the web.

Just an idea for your thoughts.
