    "goal": "Store renewable energy by converting water into hydrogen and oxygen using radio-frequency energy.",
    "problem_addressed": "High cost and limited capacity of batteries for large-scale renewable energy storage.",
    "concept_summary": "The system uses a 10-30 MHz radio-frequency field to resonantly vibrate water molecules, causing dissociation into hydrogen and oxygen. The hydrogen is collected and stored for later conversion to electricity or fuel.",
    "detailed_description": "Fresh or salt water is atomized into droplets and exposed to a resonant RF field (~=10-30 MHz). The RF energy adds vibrational energy to the H_2O bond, breaking it into H_2 and O_2 gases. The gases are separated, filtered, and stored in containers. When energy is needed, the stored hydrogen can be fed to fuel cells or combustors to generate electricity. The process is claimed to achieve ~89 % conversion efficiency, surpassing conventional electrolysis (~60 %).",
