    "problem_addressed": "Lack of efficient, low-cost propulsion and gravity-control methods for space travel and other applications.",
    "concept_summary": "Brown hypothesises that matter contains 'gravitational isotopes' whose inertial and gravitational masses can be altered by electrical potentials, photon irradiation, or friction. By applying high-voltage fields, UV light, or charged particle impacts to materials such as quartz or silicates, he reports weight loss, thrust, or dielectric effects that could be harnessed for propulsion or energy generation.",
