Abstract
Abstract Generating stations which each have a rotary voltage step-up mechanism integrated with an inertial energy storage device are connected in series through a transmission line to produce high-voltage utility electrical power from distributed primary energy sources, such as arrays of solar energy panels, wind-driven generators or the like, which may be intermittent. Each station in the series may include an elevated generator supported on insulative structure and operating at the high-voltage level of the transmission line to add an increment of voltage and power to the line. The generator is driven through an insulative drive shaft by a motor operated from the nearby primary energy sources. Each station further includes a massive flywheel secured to the drive shaft assembly that links the generator and motor in order to store locally developed energy during periods of excess supply whereby energy may be continued to be delivered to the transmission line during periods of diminished supply or to meet demand peaks.
