They proposed turbines that are higher than the Empire State Building, and would generate 130,000,000 kilowatt/hours per year at a cost of $ 1,100,000, not adjusted for inflation. Not such a bad idea. ::Modern Mechanix
The surveys which have been made in Germany show that, with little variation, wind velocities of 22 miles an hour are quite constant at the height illustrated. To utilize this most effectively, instead of small wheels, it is proposed to erect on each wind-turbine tower three power wheels, each 530 feet in diameter. The whole weight is so counterbalanced on bearings that it faces the wind; while the angle at which the wheels encounter the air currents is depending upon the velocity of the wind. If this is very high, as in a storm, they present their edges only; if the currents of air are light, the wheels take a vertical position, as illustrated in the detail at the lower right of our illustration. The wheel will begin to rotate in a breeze of but 4 miles an hour and, because of its great inertia, will turn steadily.
The method of generating the power is unique. Instead of gearing the great wheels to a generator, as in previous construction, each wheel is itself made the rotor of a great electrical generator. The rings are double; the armature and field coils are built into the outer and inner rings, respectively; and the output is fed into a distributing system, which has the necessary transformers and converters. The inventor plans 40,000-volt direct-current transmission lines. The cost of each 30,000-horsepower unit is estimated at $1,100,000; delivering 130,000,000 kilowatt hours a year with slight cost for maintenance.
The first experimental tower to be erected is to be 665 feet high, with 200-foot turbine wheels, and located near Berlin.
