    "inventor_name": "Graham Gunderson",
    "publication_year": null,
    "device_name": "Solid-State Electric Generator",
    "goal": "Generate electrical power with efficiency greater than 100 % (over-unity) using a solid-state magnetic flux synthesis without moving parts.",
    "problem_addressed": "Magnetic braking in conventional generators reduces efficiency and requires large mechanical power input; the invention seeks to eliminate this loss and achieve higher power density.",
    "concept_summary": "A permanent-magnet field is coupled into a magnetically soft ferromagnetic core that contains holes. An input coil drives flux flux, causing the magnetic field to appear to move (virtual motion) within the core. An output wire threaded through the holes intercepts this moving flux, inducing an electromotive force without any mechanical motion. The design claims to suppress Lenz-law braking and produce over-unity power conversion.",
    "detailed_description": "The generator consists of one or more permanent magnets (e.g., NdFeB, SmCo, ferrite) positioned inside or adjacent to a ferromagnetic core made of soft magnetic material (amorphous alloy, nanocrystalline alloy, powdered iron, silicon-iron, etc.). The core is drilled with radial holes. A primary coil (input winding) encircles the core; when an alternating voltage is applied, it modulates the magnetization of the soft core, causing the effective position of the permanent-magnet field to vibrate. A secondary wire (output winding) passes through the holes in an undulating pattern, cutting the moving flux and generating an output voltage. The device claims to synthesize magnetic motion, reduce Lenz-law braking, and achieve high conversion efficiency without any moving parts. Various embodiments allow different core shapes, hole patterns, and magnet configurations, and the output can be taken from the output wire or from a superimposed DC bias.",
