— What is the point? — Says Viktor. — As you know from the school course, a pair of warm air from the land rises to a height it cools, condenses, and eventually precipitation. But this mechanism is not always, but only at a certain relationship between the relative humidity, temperature and altitude. Can artificially create such conditions, it will rain. Say, a simple formula is: if the street plus 30 degrees Celsius and humidity of 50 percent, you have to raise the moist air to a height where the temperature plus 15 Celsius, and to begin condensation.
But how to raise the air? Not in the same cylinders to pump? The scientist has hung in tiers balloon garlands large area. Made of blackened material, they will be very hot in the sun and release heat to the surrounding air. And now he rushed up, where each successive layer receives additional heating. And so on until the air reaches the design height. There he is prepared to ensure that spill onto the ground.
But this condition is necessary but not sufficient. Need more points or "seeds" of condensation — the dust, aerosols, ash, soot. Or better, if the particles have a negative charge. And the scientist knows where to take them. It turns out, they immediately at hand. After all, between the Earth and the ionosphere potential difference, which is at an altitude of two kilometers of 200 kilovolts. To get the ions have to raise this height grounded conductor, there is a corona discharge, and the ions are formed themselves.
Beautiful idea, but immediately raises many questions. To what height to lift the air? Long as it takes to make it rain? How long will all this take?
— Air should raise about 700-1500 meters, — explains the scientist. — It will take about 4-5 minutes. It is crucial that the height does not need to "inject" a lot of air. Enough, as head of a pin, punch a few "holes" in the so-called inversion layer.
The fact is that in the atmosphere the air cools with altitude. But at some altitudes, there is a layer where the temperature stops falling. Moreover, even hot. Behind it falls again. Beneath these layers occur clouds good weather, such cumulus. They can not go higher, since the fibers are not allowed. "Our task — to break — said Pavlyuchenko. — Then updrafts from the earth, which are constantly rush upstairs. Thus include a self-sustaining system." According to the scientist, the price of such a facility tiny, say, one story — about 1-3 thousand dollars.
In addition, such a system could not only the rain, but also cleans the air from the smog of cities located in the basins. Winds it is not seen, so this method would come in handy. He has just received a patent for his invention.
Over the past 40 years the amount of fresh water for each person in the world fell by 60 percent. Over the next 25 years is expected to decline as early as 2 times. According to UN figures, more than two billion people in the world suffer from a shortage of drinking water, and in 2025 this figure will increase to three billion. The disadvantage, especially in the Middle East is already leading to political tensions between states.
