I thought about the idea for awhile after hearing about being stranded on a deserted island on a TV show. It went along the lines of what could you
eat? I thought to myself, what would you drink?
I could spend hours researching water desalination techniques, and build a thread explaining the techniques to make saltwater safe to drink, so I
thought instead, hey, let's throw this one out to the ATS crowd. On that premise, we are bound to learn many practical techniques to do just that.
Many scenarios come to mind where everyone should know one trick or another.
1. You are on a plane, and it crashes on a deserted island, with no resources available. What's the means by which to get freshwater (of which you
have none), from the sea, (which is all around you) and have enough water to survive on?
2. Cruise ship, same scenario, it sinks and you wash ashore somewhere. How do you get freshwater to drink until the rescue crews arrive?
3. The Collapse occurs, chaos all around, yet you are near the ocean, but cut off from supply lines. You need to make your own water to drink from
I did a tad of research, and rather than go in-depth, I chose to see what ATS comes up with. Here's a bit of info to get you started:
Thirsty? How 'bout a cool, refreshing cup of seawater?
No, don't take us literally! Humans cannot drink saline water. But, saline water can be made into freshwater, which everyone needs everyday. The
process is called desalination, and it is being used more and more around the world to provide people with needed freshwater. Most of the United
States has, or can gain access to, ample supplies of fresh water for drinking purposes. But, fresh water can be in short supply in some parts of the
country (and world). And, as the population continues to grow, shortages of fresh water will occur more often, if only in certain locations. In some
areas, salt water (from the ocean, for instance) is being turned into freshwater for drinking.
Here are our parameters for saline water:
Fresh water - Less than 1,000 ppm
Slightly saline water - From 1,000 ppm to 3,000 ppm
Moderately saline water - From 3,000 ppm to 10,000 ppm
Highly saline water - From 10,000 ppm to 35,000 ppm
By the way, ocean water contains about 35,000 ppm of salt.
The worldwide need for freshwater:
The scarcity of fresh water resources and the need for additional water supplies is already critical in many arid regions of the world and will be
increasingly important in the future. It is very likely that the water issue will be considered, like fossil energy resources, to be one of the
determining factors of world stability.
Okay, so my OP doesn't need to be so fantastical such as a plane crash on a deserted island. There already a freshwater shortage, and the demand is
overwhelming the supply. It appears to be a tenuous balance worldwide.
So, ATS, feel free to respond. We need freshwater, from salt water, in a survival scenario. Solutions?
