There is water everywhere in the sea, but you cannot drink it. This leads to rapid dehydration of the body. By drinking salt water, you will die even faster than without water at all. However, with a penknife or razor and a couple of items that are easy to find, you can create an impromptu desalination system. A simple desalination plant that uses the sun and the most common saltwater resource in the sea.
Transformation of sea and salt water into drinking water, an improvised desalination plant from a plastic bottle and an aluminum can for drinks.
To make a desalination plant, cut the bottom from an empty cylindrical plastic bottle with a knife or scissors. The bigger it is, the better. Leave the cap screwed on. Carefully peel off the cut part. Then cut and remove the top of the aluminum can for beer or other drinks.
Bend the bottom of the plastic bottle inward so that a groove about 5 cm high or even more forms. Fill an open aluminum can with sea or salt water and place it on a hard surface in direct sunlight. Place a prepared plastic bottle over the top of the aluminum can. Its cover must be closed. Everything. The simplest desalination plant is ready.
From the heat, sea or salt water will evaporate. And these vapors rise and condense on the inner surface of the plastic bottle. While the salt remains inside the aluminum can.
When drops collect on the walls of the plastic bottle, they flow down and end up in the gutter you created. Keep this improvised desalination plant in the sun until enough drinking water is collected in the gutter of the plastic bottle. Then just unscrew the lid and drink.
Drinking mode of a person in extreme and emergency conditions.
Although in order to be prepared for emergencies, a person should drink about 4-5 liters of water per day, in conditions when it comes to survival, you can do with one liter of water per day. That is a quarter of the norm, and even less if you manage to find foods with a high moisture content. For example, fish and algae.
If there is no drinking water at all, a fatal outcome will occur in 3-5 days. Depending on the temperature of the environment, the characteristics of the body of each individual person and the initial level of hydration.
