    "goal": "Extract energy from gravitational and electromagnetic fields to produce electricity with over-unity output, addressing the world energy crisis.",
    "problem_addressed": "Global energy shortage and dependence on conventional fuels.",
    "concept_summary": "The theory proposes that electromagnetic and gravitational fields (often called Zero Point Energy) can be \"lead out\" using pulse forces applied to oscillating systems such as pendulums or rotating wheels. By synchronising a pulse force at resonance, the device allegedly extracts energy from the field, converting it to electrical power via magnetic induction or other transduction methods.",
    "detailed_description": "The core prototype consists of a pendulum or rotating wheel equipped with a metallic wire that cuts magnetic field lines, generating electricity. A pulse-force actuator supplies periodic pushes at the resonant frequency, which the inventors claim continuously draws additional energy from the surrounding electromagnetic or gravitational field. The system may be powered by a falling weight in a water-filled tube, a simple gravity-wheel, or a more complex electromagnetic resonator. Demonstrations were reportedly given to Chinese officials, and plans were announced to build four 5 kW units for university testing and wider distribution.",
