1 500 million people need clean drinking water
The supply of quality drinking water is dramatically insufficient in the world. According to official estimations about 1 500 million people on Earth do not have enough quality drinking water. Every 8 seconds one child dies because of drinking contaminated water.
There is an urgent need to provide drinking water to humanity, especially in arid regions!
Give water – Give life!
Water from air?
Air humidity is potentially a very promising source of clean water. This potential is vastly unknown, because people do not realize that immense quantities of water are contained in thin air in the form of water vapor. Under normal conditions, a cubic km of air contains enough water to constitute a river 1 000 m long, 15 m broad and 1 m deep. This amount of water (15 000 000 liters!) is equivalent to the daily supply of drinking water for 5 million people. There is an unlimited supply of humid air on Earth.
Even in dry places, such as the Sahara, each cubic kilometer of air contains a river 1 000 m long, 3 m broad and 1 m deep! The air humidity is constantly renewed by winds from the oceans and, therefore, cannot be exhausted. Air contains ten times more water than is carried in all rivers of our planet and is an unlimited source of clean water on Earth.
All water on Earth comes from air in a perpetual water circle. Air always contains water. It rains when the saturation limit of water in air is exceeded. In vast regions this does not happen and they are dry, infertile and unsuitable for life…
Is it possible to get water from air without rain?
In principle yes! Several attempts have been made in the past. For example, air was cooled down, so that water condensed and could be recovered. However, the water yield from one cubic meter of air was only about 10 ml. For this tiny volume 1,000 liters of air had to be cooled close to 0 °C. Such a procedure requires tremendous energy, expensive machines and construction. Water obtained has the quality of condensed smog, it contains dust, it is contaminated by bacteria and must be therefore intensively purified. All this makes the whole cooling process complicated and very expensive. No wonder that it is not used on any significant scale to this day. The same holds true for other attempts to harvest water from air.
