ABSTRACT:
An energy storage system, and related method, comprises a plurality of wind turbines, each with a vertical shaft that passes through a support platform. One or more braces may be affixed to each vertical shaft at one end of this platform, at an angle of less than 60 degrees, preferably about 45 degrees. At least one heavily weighted device is configured and disposed to be raised with rotation of the wind turbine about its vertical shaft. The subsequent lowering of that weighted device generates electrical energies for immediate use. Alternatively, the weighted device may be suspended for storage of energy and subsequent use. Preferred embodiments include at least one energy storage system for holding excess unused energy. Representative devices include a weighted cylinder on a shaft or cable, and one or more railcars on a series of inclined tracks.
