Yes. Anywhere there's water, there's the possibility of distilling it provided you have the materials. You'll need a heat source, container for boiling, some type of collector and a condenser to condense the steam back into water. Unfortunately, that stuff may not be on your island. The best bet would be to go to the center of the island and try to dig down to water or look for another natural source like rain puddles, ponds or streams but remember, there's a high probability of parasitic infection drinking from standing water pools.Hi
If I'm stuck on an island with no water is it feasible to boil salt water and collecting the steam for drinking (after the steam has cooled down it will be distilled water) or would that take forever make all the water one needs?
It would probably take far too much wood (fuel) to condense enough water to sustain yourself without proper equipment though. Probably not the best method if you're randomly stranded.
