How to Make Seawater Drinkable
Desperate times call for desperate measures. When you are in a survival situation, you have to find water in any way that you can, even if it results in drinking seawater. It is possible to use seawater and even urine to develop freshwater by condensation. It employs the same concept as a solar still. Here are step-by-step instructions on how to make freshwater out of seawater:
1) Place the seawater in a bowl, with a cup in the center.
2) Drape a plastic sheet over the bowl and tie it down.
3) Place a stone in the center, forming a cone over the cup.
The idea behind this is that the air under the plastic will heat up, and as the seawater warms, it will condense into freshwater, on the underside of the sheet.
Another way is to distill the seawater. This can be done by boiling the seawater with a cloth covering the pot. This will collect the steam. Using about several cloths, use a stick to take the cloths off the pot, wait till it cools, then wring out the pure water in them.
The method I have just shown you as well as other survival techniques on this site are recommended to only be use in survival situations.
