How much energy will it take for dozens of jet engines to maintain a "wet" and half-filled balloon that does not have time to "descend" in heavy rain at an altitude of km?

And you have already agreed with all the winds so that they did you sway your kilometer-long pipe? Do you have any idea how to build a kilometer-long pipe? I'm not very good.

And there are no rain clouds at an altitude of 2 km.

God, why did I answer this.

If you raise into the sky and anchor a round funnel balloon with a diameter of 320 meters to a height of 1 kilometer, then the catchment area will be 100,000 square meters. Let the precipitation fall 10 meters per year. Total 1 million tons of water. We get one billion ton-force meters, which is equal to 3 million kilowatt-hours, which at a price of 15 cents per kilowatt-hour will give us 450 thousand dollars of income per year. If the balloon costs 3 million dollars, then in 6.5 years we will recoup the costs and get energy for free. This is five times faster than at a hydroelectric power station (taking into account 15 years for the construction of the latter), but you can raise the balloon up to 2 kilometers (the balloon will not just collect rain, but will become the center of condensation of vapors from the air - like mountains, you just need to stretch the networks for "catching" dew) - it will be more difficult, but more effective. The water consumption on the turbogenerator will be only 35 liters per second with a pressure of 100 atmospheres (at a height of 1 km), so the pipe can be thin (two hundred will go). In addition, the cables (and there are dozens of them) that hold the balloon are attached to spring-wound winches, a ratchet and a generator. Any shocks caused by winds and pressure drops in the sky are mitigated by unwinding the cables while generating electricity. (as in a wave electric st.) ... All this can be done in shallow waters in a place rich in rains, which are abundant in the tropics, by attaching ropes to a decommissioned supertanker, into the tanks of which valuable distilled water (1 million tons per year) need to trade, and which will double the income. Places on Earth and the ocean are suitable, where there are no mountains (you cannot build a hydroelectric power station), and it is expensive to build a thermal power plant or a nuclear power plant (no fuel.). For example, the islands of Oceania, where there is a lot of rain. There is such a place on Earth - the Atacama Desert, where there is no rain at all, but the weather is cloudy: clouds sweep by, such is the paradox. This is where such a balloon would come in handy: it gave precious water and - at the same time - electricity. In the future, to increase the catchment area, one can imagine a celestial funnel with a diameter of 1.5 kilometers or more. It will not work to build a single balloon here, and it is not necessary. A round canvas tent is taken, hung around the edges, like beads, with dozens of not very large balloons, it rises into the sky, stretched by stretch ropes, and in the center is a pipe, etc. Such an awning-funnel can be spread over the water near the shore, or covered with this "reverse umbrella" a chemical plant, at the same time supplying distilled water and electricity. You can cover the city area, sports complex, etc. from rain and tropical sun. The Millennium tent in London, or the Khan Shatyr in Astana are comparable objects. Who will invest?
