The use of a distillation system (still) is an economical and reasonable to make fresh / purified water from sea water on extended trips. I have used my small aluminum 2 liter pressure cooker with a 6 foot length of plastic tubing to make about .5 liters/hr. with no difficulty. I attach the tubing to the center vent on the lid of the pressure cooker and with my Peak 1 stove at a medium-medium low setting I can fill up a ½ liter bottle in about an hr. It certainly can also be done on a wood fire or any other source of heat sufficient to boil the water gently. It is not the fastest way but on a trip you have, time, an unlimited source of sea water, a stove, and a pot (pressure cooker for camping is about $26) and it is very easy to bring a piece of flexible plastic that will fit tightly on the center vent (I believe that it is about $.25/foot in your local hardware store. You can also drink the water with confidence since it has been boiled and condensed leaving most everything behind (salt, bacteria, microorganisms, silt, pollen etc.).
