    "inventor_name": "Antonio d'Angelo",
    "publication_year": 1928,
    "device_name": "Inter-Atomic Ion Motor",
    "goal": "Amplify the power obtained from an electric battery to supply lighting, heating, and propulsion with a motor that claims to generate many times the input power.",
    "problem_addressed": "Low-efficiency power conversion from batteries and the need for cheap, portable electrical power for homes and transportation.",
    "concept_summary": "The motor-generator uses a stationary pole-armature and a rotor with primary and secondary windings of different pitch. The secondary windings encircle multiple poles, causing rapid flux changes that induce a higher electromotive force than the input battery voltage. The inventor attributes the excess power to \"inter-atomic ion energy\" released by the ions within the machine.",
    "detailed_description": "The invention comprises a stationary armature made of insulated soft-iron sheets with eight long poles and a rotor with four poles. The primary winding is wound on the stator poles with a short pitch, while the secondary winding has a much larger pitch and each turn encircles two or more poles. Direct current from a battery is supplied to the rotor windings via slip-rings and brushes; the rotating magnetic field of the rotor cuts the secondary windings, inducing a voltage that is claimed to be several times larger than the input. The patent describes a method of winding that reduces self-induction and sparking, and outlines several configurations for converting DC to AC, stepping voltage up or down, and producing multi-phase output. The inventor calls the additional energy source \"inter-atomic energy of the ions,\" but provides no physical mechanism beyond this description.",

        "\"He showed how it started to develop energy from an electric battery, and how this original impulse worked on the machine to generate many times its power through the 'electricity produced by the inter-atomic energy of the ions'.\"",
        "\"The motor-generator illustrated in Figures I to V of the drawings is used for transforming direct current into a two-phase alternating current;\"",
        "\"The pitch of the secondary windings is much greater than the pitch of the primary windings. The secondary circuit consists of windings divided onto a plurality of coils, the turns of which encircle or surround two of the poles.\"",
        "\"Since each turn of the secondary winding encircles two poles of the stationary armature, one coil of the secondary winding is subjected to four variations of the magnetic flux in one half cycle.\"",
        "\"The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawings...\""
