"What I really need is a droid that understands the binary language of moisture vaporators." "Vaporators? Sir, my first job was programming binary loadlifters—very similar to your vaporators in most respects."
A moisture vaporator was a relatively simple device used to harvest excess atmospheric humidity. It was ground-based and used on planets such as Tatooine.
The device comprised any number of tall slender refrigerated pipes (usually one). When hot, moist air came into contact with one of the frigid tubes, the humidity immediately condensed into droplets of pure water that ran down the tubes and into underground storage tanks.
A properly maintained moisture vaporator could usually collect enough water to sustain three average Humans, even on hot desert planets like Tatooine, and Geonosis; water could be collected from air with a moisture content of as little as 1.3%[1]. Because of the delicate nature of the machines, regular maintenance was usually required.
Patch-in droids were often used as counterparts to the vaporators, as the droids translated the binary language they spoke, for the benefit of the operators.[2]
Farmers called a moist and dark area under the vaporator that commonly housed vaporator mushrooms the mushroom patch.[3]
