    "device_name": "Hydrogen Generation System",
    "goal": "Produce hydrogen without chemicals or electrolysis, eliminating greenhouse-gas emissions and reducing cost compared with conventional hydrogen production.",
    "problem_addressed": "Conventional hydrogen production emits large amounts of CO_2 and other pollutants, requires expensive infrastructure, and relies on fossil-fuel-derived electricity.",
    "concept_summary": "Joi Scientific's \"Hydrogen 2.0\" system uses a pulsed-DC driver signal and a set of reactive circuits (positive, negative, and feedback) to excite a hydrogen-generation chamber containing seawater (or other feedstock). The chamber contains a hollow cylindrical anode and a tungsten cathode. The processed signal induces hydrolysis that yields hydrogen gas without the need for traditional electrolysis electrodes or chemical catalysts.",
    "detailed_description": "The patented system consists of a signal-generation unit that creates a pulsed DC driver signal. This driver is filtered and fed to a signal-processing block containing a positive reactive circuit (inductor-capacitor network), a negative reactive circuit (inductor-capacitor network), and a feedback circuit (capacitor and asymmetrically conductive component). The processed chamber-excitation signal is applied to a hollow cylindrical anode that holds the feedstock (e.g., seawater). A tungsten cathode is positioned along the axis of the anode. The interaction of the excitation signal with the feedstock causes hydrolysis, producing hydrogen gas which can be collected for use in fuel cells or combustion engines. The system is modular, rack-mountable, and designed for scaling from 500 kW to 100 MW plants.",
