A wind-driven power source comprises a propeller-driven rotor structure and a stator structure carrying clusters of copper-wire wound ferromagnetic cores as voltage generators. The cores are arranged in pairs spaced apart by hard rubber rollers which engage the inside surface of a load ring forming part of the rotor structure. The overall rotor structure comprises the large diameter load ring, a smaller diameter root ring and a plurality of aerodynamic blades extending radially outwardly from the root ring and secured either by saddle blocks or integral bonding to the load ring. The load ring may be aluminum or plastic. Permanent magnets are arranged around the load ring to interact with the voltage generator structures to produce three-phase electricity.
