    "inventor_name": "Randall Mills",
    "publication_year": 2025,
    "device_name": "Space Drive",
    "goal": "Provide reactionless propulsion capable of lifting large masses without expelling reaction mass.",
    "problem_addressed": "The need for propellant-free thrust for spacecraft and vehicles, eliminating the mass penalty of conventional reaction-based propulsion.",
    "concept_summary": "The Space Drive claims to generate lift by a free electron absorbing a photon while moving relative to an absolute-space inertial frame, transferring photon energy to electron kinetic energy without a conventional reaction partner. The effect is manifested as directional plasma confinement and supersonic plasma jets that produce measurable lift when driven by short bursts of microwave power.",
    "detailed_description": "A high-vacuum chamber is filled with an argon-hydrogen plasma (~=5 % H_2). Microwave power (~=330 W) is applied for ~40 ms, creating a plasma jet that is confined by the proposed \"space-drive\" mechanism. The lift is observed as a supersonic propagation of plasma pressure that pushes a quartz weight plate upward, producing a measured lift of 46.9 kg (103.3 lb). The measured lift matches theoretical predictions based on the photon-electron interaction model. The device demonstrates a weight-to-power ratio of roughly 3 W/lb, far exceeding conventional rocket propulsion metrics.",
