    "goal": "Generate a self-energizing, free-energy source that can produce thrust and weightlessness for spacecraft.",
    "problem_addressed": "Need for a high-energy, low-mass propulsion system that can overcome gravity without conventional fuel.",
    "concept_summary": "Carr's Utron is described as a rotating, charged \"molecular shell\" (a hemispherical accumulator) that, when counter-rotated with electromagnets and capacitor plates, allegedly creates tensor stresses in free space, cancels inertial mass, and provides continuous electromotive force. The system is claimed to recharge from atmospheric electricity and to enable weightless, high-speed travel.",

        "There is nothing perpetual about our machine. The energies which cause it to operate are perpetual. You cannot destroy matter, and you cannot destroy energy; molecular flow is perpetual."
