    "publication_year": 2003,
    "device_name": "Thermal Energy Cell",
    "goal": "Generate continuous heat for domestic heating with far less electrical input than conventional systems.",
    "problem_addressed": "High cost and carbon emissions of gas/oil heating and the need for large storage for renewable electricity.",
    "concept_summary": "A sealed tube containing water, potassium carbonate (potash) and a secret chrome-based catalyst is passed an electric current. The mixture allegedly taps a metastable hydrogen state, releasing heat that exceeds the electrical energy supplied.",
    "detailed_description": "The device is a 12-inch tube with two electrodes immersed in a liquid mixture of water, potassium carbonate and a proprietary catalyst. When a low-power electrical current (~=1 kW) is applied, the system heats the surrounding water to near-boiling, producing up to 10 kW of thermal power. The inventors claim the effect is due to a quantum-theoretic metastable hydrogen state, but the exact mechanism is not understood. Independent tests have reported energy gains ranging from 3x to 26x the electrical input, though critics point to possible measurement errors in the electrical input.",
