    "goal": "Provide an abundant, high-energy fuel alternative to hydrocarbons by using long-chain silanes that combust with both oxygen and nitrogen.",
    "problem_addressed": "Dependence on limited carbon-based fuels, low combustion efficiency (only 20 % of air used), and the need for a cleaner, higher-temperature energy carrier.",
    "concept_summary": "Peter Plichta developed stable, long-chain silanes (5-10 Si atoms) that are liquid at room temperature. When burned, the hydrogen component reacts with oxygen to form water, while silicon reacts with nitrogen to form silicon nitride (Si_3N_4). This dual-oxidant combustion yields higher temperatures (~2000  deg C) and utilizes virtually all of the air, promising higher thermal efficiency and a non-toxic exhaust.",
