    "goal": "Increase the efficiency of electrical generators and achieve over-unity (free-energy) output.",
    "problem_addressed": "Low conversion efficiency, magnetic flux distortion, and the need for commutators in conventional DC generators.",
    "concept_summary": "An asymmetrical electro-mechanical device in which a geometrically-magnetically-asymmetrical stator and rotor move relative to each other across an air gap. The magnetic flux path is interrupted at the gap, inducing voltage in armature conductors on both stator faces. Variants include correction coils to cancel unwanted flux, commutator-less DC operation, and multiple interchangeable stator/rotor units to improve efficiency.",
    "detailed_description": "The invention comprises a stator with an air gap that makes it magnetically asymmetrical and a rotor that passes by this gap. When the rotor moves, the magnetic flux linking the stator is periodically interrupted, generating an EMF in conductors placed on both stator faces. One embodiment adds a correction coil wound around a portion of the magnetic circuit; a correction current creates an opposing magnetic flux that reduces distortion and load effects, thereby raising efficiency. Other embodiments describe a commutator-less DC machine where the rotor and stator move relative to each other, eliminating the need for brushes. The patents also claim methods of increasing generator efficiency by adjusting reluctance, supplying reactive current, and filtering DC components from counter-potentials.",
