    "problem_addressed": "Need for reliable, low-maintenance power sources where solar or conventional generation is insufficient, such as on Mars or in low-head water environments.",
    "concept_summary": "The technology uses suspended conductive fibers (carbon, graphite, graphene) that collect energy from ambient electric fields created by atmospheric ions or ionized particle mists. The collected charge is rectified by diodes and delivered to a load. Variants incorporate radioactive material to increase ionization, water-hammer shock waves, or electro-hydrodynamic mist injection to boost collection efficiency. An electrostatic motor enclosed in a hermetically sealed, gas-controlled chamber is also described, improving efficiency by stabilizing the internal atmosphere.",
