Acquiring water – distillation. Obtaining water by condensation.
A fairly effective method obtained and the water can be distillation. To this end, it dug a wide and deep in the ground 1 m. A vessel is set in it, from which a cane or a tube is protruding against the wall. An ideal way is to locate a certain amount of plant material at the bottom, containing a lot of water (Plants cut into pieces increase the condensation of steam). The bottom is covered with foil (2×2 m) Laying a pebble in the middle, to create a cavity in it. The edges of the sheet are covered with soil dug from below, so that it would not escape a bit of moisture.
As a result of heating with sunlight, the temperature at the bottom increases and causes water to evaporate from the ground and from plants. The pair condenses the foil (which is cooler) and drops in the dish with drops.
Water can be drunk with a tube without dismantling the entire device. Within 24 We will get hours from 0,5 do 1,5 1 distilled water. The system also works at night (About half of the daily portion is then obtained). The foil cools down quickly then, while the earth temperature drops very slowly.
The distiller can act as a cleansing filter: It is enough to wet the surface of the pit with sea water or water contaminated with mineral substances.
Another salt purification system (or contaminated) the water involves digging the bottom and filling it with sea water. You need to warm up a few stones in a fire -burning bonfire, and then push them with a stick into the water. Shell. The water vapor will condensate on the fabric, which then should be squeezed into the dish.
