Abstract: Apparatus for generating electrical energy is disclosed wherein an annular arrangement of rotor windings is affixed to a number of rotatable blades which radiate outwardly from a central rotatable hub. An annular stationary assembly of stator windings is coaxially positioned adjacent the rotor. Jet engines, mounted at or near the outer terminus of the blades, cause the blades and rotor to rotate about the hub and induce alternating current electrical energy into the stator windings. Some arrangements of the disclosed electrical generating apparatus include a second electrical generator wherein the stator thereof is affixed to a stationary wall that coaxially surrounds the path followed by the rotating blades. A second annular rotor assembly, including wind vanes that are subjected to airflow caused by the jet engines and rotation of the blades, is slidably mounted to the upper end of the stationary wall.
