Problem with reverse osmosis is the membranes, they're expensive and require regular replacement. I'm quite intereseted in this idea, been toying with the idea of putting a water maker on the boat. They're reverse osmosis systems driven by an electric pump. They're a bit pwer hungry, though, small units draw over 30 amps at 12v, so you're looking at pretty heavy cabling. On the plus side, they produce a shitton more water, the smallest units will do 10 gallons an hour. They're also quite compact and easy to install, but at $8000 for an entry level system it hast to stay on the wish list for now.
