Reptiles
They are not water directs. Reptiles can suck dew, or from the capture of small animals to get water, which can survive for a long time even if the anhydrous.
Insects
Insects are a very good source directs. In particular bees: they are usually not far from the hive or hive up to over 6500 meters. But drinking time there is no law. Ants also inseparable from the water, a team marching toward a tree ant is likely to go underground cistern water. Such water even in barren land may also be found. Most insects in the water within the radius of 90 meters to fly non-stop, especially when exposed to the kind of flying shining green stone body of the European bee.
Human traces
Human footprints can often take you guide well or sump. To reduce evaporation, they may be covered with shrubs above or slate. After use should be re-covered.
Condensate
Plant roots can absorb moisture from the ground. Some tree roots may extend into the ground 15 meters or deeper moisture. Person is not so effortless to dig too deep. Of course, you need not be so, you can let the tree to help you. In the period of tender leaves of trees on the sets of a plastic bag, leaf bag produce condensate. Pick strong, dense foliage twig bar. Bag down, the lower corner of the bag in order to collect condensate.
Will be a long polyethylene film coated on any biological plants can be good to collect moisture. Because increased transpiration of water vapor generated in contact with the film cold, it will condense into water droplets. Left illustration, the top of the film and suspended shut up, or stick with a resilient pad propped up. Drops of condensation. Should be allowed into the bottom of the wall along the film collecting dish. Do not let the leaves touch the film, otherwise knocked condensation water drops.
Even just cut off the fresh plant leaves in large plastic, the temperature rises, it will also produce condensate. Stones with a clean pad in the foliage below, in order to facilitate the collection of condensate. The bag taut with stones, sticks supporting elastic cushion bags top, so avoid touching foliage bag face. Plastic bags should be slightly tilted along the inside wall of the condensation of water droplets slide collection points. When the foliage becomes listless no longer have a strong transpiration, carefully and then put on a fresh batch foliage.
Salt
Salt is also a human necessity. Under the conditions of a normal diet, intake of 10 grams per person per day needed salt. If the discharge is greater than the intake, the body will be trouble. Pee will take away perspiration and salt, so the climate is warm, the more salt loss. Manual will increase the consumption of salt.
The primary symptom is lack of salt, muscle spasms, ear dizzy dizziness, nausea, fatigue and ease fatigue. Rehydration salts mode can be a pint of water add a pinch of salt dissolved drink. Your lifesaving bag with salt tablets, crushed them, and add water to dissolve. Do not swallow whole - this will cause stomach discomfort, but also detrimental to the kidneys.
If you do not run out of tape or salt tablets how to do? Located along the coast or at sea can get enough from the sea salt - a pint of seawater contains about 15 milligrams of salt. But do not directly drinkable water, it should be well diluted with fresh water. Evaporation of sea water can be obtained crystals of salt cake.
Living inland, salinity problems must be solved. In pastoral areas, you can find the cow licked the salted ground - but then you came close to the realm of civilization, the less likely will continue to lack of salt. All mammals need salt, to observe their whereabouts can be found in salt. African elephants are willing to risk the deep exploration into the dark hole, just to lick the salt wall food.
Some plants are also salt. In North America, the best is the walnut tree roots; in Southeast Asia, you can use Xiabai palm roots. Grill until the roots are all moisture evaporates, the salt crystals will precipitate black. If salt is difficult to find direct, indirect methods you can try. Animal blood at any time are not easily abandoned, because it is a useful source of mineral elements.
Daylight distillation
Daylight distiller
Dug in the ground about a 90 cm wide, 45 cm deep pit. Hang up a collection pan bottom center, as shown in the pit hanging on a pull into a curved plastic strip. Solar elevated pit moist soil and air temperature, evaporation of water vapor. Gradually saturated water vapor, in contact with the plastic case of condensation of water droplets to form, down to collection dish, this method is suitable for desert areas or areas of a large temperature difference between day and night. Plastic pieces fall faster than the air temperature, water vapor condenses very obvious. Such distillation within 24 hours to collect at least 1 pint (55 ml of water).
Such distiller also trap function. Plastic strip can attract insects and snakes, they will slide along the curved plastic strip at the bottom, when the fall of the peristaltic collecting dish.
Daylight distillation can also be used to collect water from toxic or contaminated condensate transpiration. Plastic strip to ensure that the central part of the plastic strip hanging a curved stone so water droplets can slide along the bar and fall into the collection center at the bottom of the dish (pictured above). Plastic strip ends are pressed with stones. Fixed dish will be collected in order to avoid falling into the trap of biological overturn it.
Warning: Do not drink water whenever and urine, however, by distillation, both can be used to produce potable water - water residue while providing essential salts.
Distill
Distillation vessel is a part of life-saving appliances, if not you can make the best of. In order to smoothly carry out the distillation, you need to find some room can replace real risk retort something that works. Insert one end of the hose filled with water in a closed container at the top, and the other end into a closed cooling dish, to heat water containers, water boiling steam generated administered sub-distributed to the cooling dish case of condensation to form clean water. Tubes can also be adapted to local conditions, local materials - such as backpacks hollow frameworks. In order to avoid steam shed, mud or wet sand with a closed pipe joint between the gap and the container.
Plug one end of the tube flap container, container contained sewage to be boiling, salt water or even urine, and the other end into a solar distiller inside. Bark covered with a metal plate or the container mouth. Used as a cooling dish daylight distiller mouth can even use leaves rolled into a cone to cover, which helps to gather steam.
Ice and water
Snow melted water
Easier than the melting snow melting ice - requires less energy, faster more of water from; same energy, the former can produce double the amount of water. If you only use the snow, the snow should be melted in a small jar, and then gradually increased, and a large number of blocks of snow into one of the drawbacks, the bottom of the first snow melt into the upper part of the water will be sucked soaked snow, this will produce hollow, is not conducive to further heat the pot will even burn.
Sea ice of the water
High salinity sea ice - into water is undrinkable unless's very old ice, airsoft mask
, salt content less. The more recent era of ice, the higher the salt content of these ice rough outline, generally milky white. Alternating ancient ice due to climate impact is not so smooth edges, the general was sky blue.
