In Arizona, to build a "tower of Babel solar"

However, such people are found only overseas – "Babel solar tower" will be built in Arizona. Details – under the heading of Nikolai Grinko on the radio "Vesti FM." A little about the project. The basis of power is the greenhouse – construction of metal and glass, built in the shape of a circle diameter of nearly two kilometers. At its center will elevate the pipe diameter of 130 meters and a height of 800. At the base of the pipe installed turbines and generators – that is, in general, and all the power description. In the Arizona desert, the air is heated to 40 degrees Celsius, and under the glass roof, its temperature can reach 80 degrees. Since the high-altitude atmospheric temperature is lower streams of heated air will rush into the pipe, turning the turbine blades passing. Interestingly, the work station will not depend on the absolute temperature of air in the greenhouse, home here – a difference of several degrees between the upper and lower layers. Therefore, the solar tower will be able to work on a cloudy day, and even at night, because the soil heated by the day, be able to maintain the temperature in the greenhouse. Calculated efficiency of this method of converting solar energy – about 60 percent of the peak power of 200 megawatts. That's enough to feed about 100 thousand households or typical American town with a population of over a hundred thousand people. The developers claim that the tower power plant would require virtually no maintenance other than periodic inspection and possible repair of turbines and generators. Our version is fully welcomed the development, wondering just why such a simple, in general, the idea has not yet been implemented in practice. Troubling, only one – the engineers plan to build on top of the tower observation platform for tourists, and no member of the editorial board is not prepared in good faith to climb the 800-meter height.
