Patent ID: 7612463

Claim:
An electrical power generator is provided which comprises a stationary frame connected to the ground, a rotating frame carrying an electrical generator(s) to generate electrical power within said rotating frame, and a rotating transformer arranged to transfer said electrical power from the rotating frame to the stationary frame, the transformer being of a rotating transformer type comprising a stator and a rotor arranged to rotate about an axis of the stator core with a gap therebetween, said rotor and said stator being arranged coaxially wherein said rotor is arranged radially about said stator, said stator and said rotor respectively having electrical windings arranged to create a magnetic flux which circulates between the stator and the rotor upon application of said electrical power as an alternating electrical current in one electrical winding in either the stator or the rotator so that a voltage is induced in the other electrical winding relative said alternating electrical current for a driving electrical current so that electrical power generated within said rotating frame is transferred between the windings across the gap between the stator and rotor despite relative rotation about an axis of the stator core, said stator having a hollow core for electrical cables coupled to the winding for delivery of said driving electrical current, said rotating frame carrying a power source to drive rotation, said stationary frame comprises said electrical cables, said rotatable power source being arranged to drive said electrical generator, said power source being at least one turbine having blades driven by the force of a fluid acting on said turbine blades wherein said at least one turbine is a wind turbine designed to operate at high altitudes wherein said wind turbine is free from a rigid connection to the ground and wherein said stationary frame comprises said electrical cables.
