Wanting to obtain water from the soil, You should build a sun heated boiler. If a temperature difference arises between two surfaces, The air will warm up and saturate with water vapor, which sprinkled on a cooler surface and will flow.
Boiler construction
Trench in the ground a width of approx 1 m and depths 30 cm. Set the vessel at the bottom. Cover the bottom with foil, and its edges of the stone to chase. Wear the center of the foil with a fist size stone, that it hangs exactly above the vessel. When under the influence of the sun the air heats up, The water vapor will start to settle and condense on the cooler surface of the foil, and then flow into the dish. Such a boiler works very well in the desert both during the day, and at night. At night, the air over the bottom cools faster, thanks to which it is still warmer, So there may be condensation on the surface of the foil.
Condensation of sea water
Sea water or urine can be treated with the same condensation method, which is used when obtaining water from the soil. Pour sea water into a bowl, in the middle of which put a cup. Stretch a piece of foil above the bowl and attach to the edges. Put a stone on it, that he burden the agent. The air in a bowl under the foil is heats up, That's why sea water will start to evaporate. The water vapor condenses on the foil as sweet water and flows into the cup.
