    "problem_addressed": "High fuel consumption, pollution, and inefficiency of conventional steam/diesel power generation.",
    "concept_summary": "The invention proposes a structure that couples the Earth's gravitational field with a high-intensity magnetic field. A bowl-type energy concentrator axle loaded with liquid space, together with eccentric high-strength magnets and a geometric governor, creates a repulsive force that drives a solid-shaft output axle, producing smooth, low-noise rotation without apparent fuel consumption.",
