.72 Fresh water from the sea (Sunwater Company solar stills installations). This retirement home in Mexico is 200 miles from the nearest source of drinking water. The 1400 gallon reservoir steres sea water to supply the toilet, other household needs, and the 3 g.p.d. still-- which is seen on the roof. An automatic feeder, the rectangular object on top of the cylindrical fresh water reservoir, keeps the still in operation indefinitely, as long as there is sea water in the feed reservoir. Fresh water, automatically stored during the owner's occasional absences, is available with the turn of a tap at the kitchen sink. With this system, resort and retirement homes can be built anywhere in the world, depending on the sea and the sun permanently for fresh water!
