Free, clean drinking water from dew, fog etc

I was thinking of a large dish, used I think in Africa. Can’t remember the specs, and can’t find it on Google, but it seemed pretty impressive (I think it was a bit more than simply a large dish).

Also, would there be a simple, cheap machine, perhaps using coils, that could convert moisture into water?

Actually, at the worst, you’re probably going to then be close enough to civilization that you can get clean water from a tap!

Got one already. What I really need is a good protocol droid.

any kind of refrigeration device with air blown through i will result in condensation/ice forming on cold surfaces.
