    "goal": "Increase internal combustion engine torque and fuel efficiency by modifying oil charge and magnetic fields",
    "problem_addressed": "Low fuel economy, high fuel consumption, limited engine torque in conventional IC engines",
    "concept_summary": "The Hull Effect proposes charging the carbon particles in engine oil (or removing charge) to magnetize the engine block, creating a stronger spark and a magnetic field that alters thermodynamic heat exchange, reduces fluid drag, and improves combustion. The system uses alternator voltage spikes routed through a light-dimmer circuit into the oil stream, generating high-voltage bubbles and a plasma-like reactor inside the engine.",
