Wind Turbines, 1932 Version, Costs $1 million, Generates 130 Million kilowatt hr

By Chris V. Thangham     May 2, 2007 in Environment
A $1 million Giant Wind Turbine can generate 130 million kilowatt hours enough to power 144,000 homes per year.
German Engineers in 1932 created special wind turbines that could supply a large amount of electricity at affordable rates. They found that the wind at the surface of the earth is not the best place to install a turbine, where the speeds are low and uncertain, but the same winds thousand feet above the ground, is comparatively steady and dependable. At that heights one can harness wind power at a high rate. This wind power generation has excellent potential to generate electricity compared to the limited hydraulic power available at that time. The design here was prepared by a German Engineer Honnef, the builder of several huge radio towers. The structure used for this wind power generation will be taller than any other building.
Germany recently wants to adopt a similar wind turbine for electricity generation. Researchers surveyed wind velocities at the height the previous model stipulated. They found the wind velocities at 22 miles an hour and constant speed, which will be good for wind turbines don’t have to rely on uncertain winds they face at the ground.
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.
They are designed to cope up with storms and the wheels will start rotating at a speed of 4 miles an hour. Compared to other wind turbines which have to connect through many steps to generate power, this turbine can generate electricity directly; each wheel becomes the rotor of a large 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 company is planning to have 40,000 Volt direct current transmission lines; the cost of each 30,000 hp unit is estimated at $1,100,000 and delivers 130,000,000 kilowatt hours a years with only a slight cost of maintenance. A home uses on an average 700 to 900 kilowatt hours, then 144,000 homes can be powered with one turbine.
The new experimental tall tower will be built, a height of 665 feet with 200 foot turbine wheels and located near Berlin. If this is successful, more will follow.
It is an interesting technology hope the utility companies will do more of this in the future.
