    "publication_year": 1995,
    "device_name": "Fuel Additive for Internal Combustion Engines",
    "goal": "Increase the energy output of hydrocarbon fuels by adding stable isotopes that fuse with protons during combustion, thereby providing additional power.",
    "problem_addressed": "Low energy density and efficiency of conventional hydrocarbon fuels in engines and turbines.",
    "concept_summary": "Stable isotopes such as lithium-7 or boron are mixed into conventional hydrocarbon fuels. During the high-pressure, high-temperature event of ignition, some of these isotope nuclei fuse with released protons, releasing fusion energy that adds to the normal combustion energy, theoretically yielding many times the conventional power output.",
    "detailed_description": "The patent describes a fuel composition comprising a conventional hydrocarbon base plus a small amount (e.g., 0.1 % by weight) of a stable isotope capable of nuclear fusion with protons (Li-7, B-H). The fusion events occur under the extreme pressure and temperature conditions of the combustion chamber, producing mass-defect energy that supplements the oxidation energy. The invention claims that even a 1 permil addition of Li-7, with only 1 % of the nuclei fusing, can provide up to 50x the normal combustion energy. The document also mentions required engine compression ratios (~=1:11 to 1:20) and suggests using a separate additive tank to control dosing. No peer-reviewed data or independent replication is presented.",

        "Addition of a very small amount of Li-7v3, for example 1 pro-mille, of which only 1% of the Lithium nuclei would fuse with rondvliegende protonen, would then still yield 50x the energy of the combustion of the conventional fuels to which it has been added.",
        "He advises a lot of tuning and tweaking to get the settings right. He advises to use a separate tank and fuel feed for the additive to avoid settling of components in the mixture inside the gas tank and to increase control over the exact amount added.",
        "De Geus calculates the energy output of less than 1% of fuel additive to yield over 50 times the normal energy output of the engine/cylinders. Which would obviously blow up the engine.",
        "He points out that there is no radiation and no waste isotopes, and that after over 1000 miles his engine showed no signs of negative effects.",
        "The mass defects of these fusion products generate additional energy to that released during the combustion process."
