Hi everyone!

I was wondering - incase of an emergency - how do I turn salty river/ocean water into clean drinking water? (Of course, the way can't include electricity in this case. :D)

Thanks!

Seawater is forced through a semipermeable membrane that separates salt from water. Because the technology typically requires less energy than thermal distillation, most new plants, now use reverse osmosis. I don't know if we can do this at home though.

Reverse osmosis "wastes" about 4 gallons of water for every gallon of clean water you get from it. We have a RO System for drinking water at our kitchen sink. It works well, but we are on well and septic so all the additional water used is not a big deal for us.
I watched a documetnary on survival in the desert (I was home sick with the flu and that was really the only thing worth watching) and they showed digging a hole, place your cup in the bottom of the hole, cover the hole with plastic and place a small stone in the center of the plastic to make it droop and let the condensation drip into the cup from there. Or better yet, take a piece of string and poke it through a tiny hole in the center of your plastic wrap so it will dangle it into the cup.

yes, even many years ago they had such setups available for a reasonable price, i'm sure things have improved a lot in the 20+yrs since i had one (for marine/reef aquariums).

Well... I watched Ed Stafford did that in his show before... I forgot the title of the series... but it a good show... you'll learn a lot about survival... and creating your own drinking water is pretty much vital...
