    "concept_summary": "A sealed aluminium cylinder containing a crystallised mixture of sodium metasilicate (Na2SiO3) and calcite (CaCO3) that allegedly produces a continuous electrical current through galvanic or unknown internal processes.",
    "detailed_description": "The device is an aluminium pipe (or cylinder) filled with a melt of sodium metasilicate and calcite that is allowed to crystallise. Internal electrodes are made of dissimilar metals (e.g., brass, copper, graphite, magnesium alloy). The crystal lattice is claimed to generate a continuous current, measured as >3000 mAh through a 910 Omega resistor, and to operate for years without external energy. Some reports mention a priming cycle, water evaporation effects, and possible contributions from radioactive impurities in the calcite.",
