New huge source of renewable energy & water supply, alternative for solar & wind
It is known that the solar energy reaching to the planet is about 10,000 times greater than the needs of humanity. About a quarter of it goes to the evaporation of water and virtually always more or less evenly accumulates in the atmosphere at any point around the world. Since the annual precipitation is about 1 m of rainfall with an average height of 5 km, this gives a potential capacity of about 810 TW, which is more than 60 times greater than all the current needs of humanity (13 TW). Standard hydroelectricity can only use a small fraction of this energy, because all precipitation lose most of their potential energy on the way to the ground to overcome the resistance of the air and hit the ground. In order to use this potential energy more cost-conscious, it is necessary to collect the water at that altitude, where it condenses, and use all possible vertical hydraulic head. This is what constitutes the essence of the decision.
Interestingly, already having gotten this solution, I began to search the Internet for key words such ideas, and unexpectedly found that in 1915 in one of the articles the genius Nikola Tesla was nearly half a step to the realization of this idea: he was correct in principle estimation of the required resource, but had not found a scheme to implement it, although all technics already was ready for it hundred years ago. It's a pity. If he then screw the idea, then we would live in a different world—clean, ecological, abundant, without wars for oil, etc... Unfortunately, humanity has lost a hundred years!
