Everyone living in a coastal area should learn this skill. If you run out of drinking water and there’s a drought or you have no access to lakes or rivers, you might have to gather water from the ocean.
The cruel irony of planet Earth is that there is water almost everywhere, but less than one percent of it is safe to drink. Not only will drinking salt water make you even more dehydrated, enough of it will cause kidney failure and death. But knowing how to turn salt water into drinking water can get you around this problem.
The simplest way to do it is the distillation method. When salt water evaporates, it leaves the salt behind. Then when the steam condensates on a surface, fresh water drips off of that surface into a container. To see what I mean, watch this video by Jenny from MomPrepares.
The downside of this method is that it takes a lot of energy just to get a little bit of distilled water. That might not be a problem if the power grid is up and running, but if the power is out then this method will require a lot of precious fuel.
One solution is a solar water distiller. This method uses energy from the sun to heat up the water. It’s a very slow process so you would need to have a lot of these going (or a few very large ones) to get enough drinking water for the day, but it could work.
Hopefully, these videos helped you understand what the distillation method is and how to do it at home. If you live near the beach, make sure you know how to turn salt water into drinking water using this method.
