    "goal": "Detect and harness the so-called Universal (telluric) Current for power, communication, and levitation.",
    "problem_addressed": "Inability to capture and use natural earth-derived currents for practical energy and propulsion.",
    "concept_summary": "Rota claimed that a non-electromagnetic energy he called the Universal Current flows a few metres below the Earth's surface. By using large buried laminated metallic blocks he could tap this energy, amplify it with a device he called the Transducteur, and convert it into electrical power, levitation forces, and secure wireless communication.",
