OK, fresh water with salt as a by product, that would be handy, but the tips by the potter are invaluable. The still is interesting, but the techniques used in building the stove are invaluable. They could be used for building a cook stove, it is actually almost a modified rocket stove, a true rocket heater, the same basic design could be used to build a beehive oven or a wood fired kiln to make the pot for azrancher or to store the water or other beverage made by the still, enhanced beer or wine anyone? The filler to the still pot acts as a safety valve and will leak before the pressure builds up enough to explode if the outlet is blocked, the clay will seal the pot, but will not get hot enough to fire, so the lid can be removed and the salt removed. One of the things the Pacific Islanders didn't have on their volcanic islands was clay and thus no pottery and the work a rounds are in themselves worthy of study.

The man with the educated hands and feet took wood and clay and created not only water, but pots, ovens, stoves, dishes, etc.
