Please correct me if I'm wrong.
No it would be distillation. Basically you put wet blankets on the ground, then hang a cone shaped plastic with the point down over the blankets. You seal the sides so that the water that evaporates from the cloth cannot easily escape, and it condenses on the bottom of the plastic, runs down to the center and drips into the bucket. This method is really more for the camper who gets lost and can easily carry some clear plastic film in his backpack. They will dig a hole, put a glass in the center of the hole, then put plastic over the hole, and a stone in the center. Does not produce much, but it can save you life if dying of thirst. I think the designs shown below are probably better, they use a box, and sloping glass or plastic: http://www.solardome.com/SolarDome84.html http://www.solaqua.com/solstilbas.html > On the other hand I > think rain water may work just fine in some areas. -- The silver-list is a moderated forum for discussion of colloidal silver.
