    "publication_year": 2008,
    "device_name": "Electro Magnetic Energy (EME) motor",
    "goal": "Create a high-efficiency motor that can run for long periods without external power, using permanent magnets as the primary energy source and thereby replace gasoline engines.",
    "problem_addressed": "Reliance on fossil fuels, low efficiency of conventional internal-combustion engines, and the need for clean, low-maintenance power for vehicles and appliances.",
    "concept_summary": "The EME motor uses a combination of permanent magnets mounted on a shaft and electromagnets in the stator. Positive and negative charges push and pull the magnets, while a magnetic-cushion bearing eliminates metal-on-metal contact. The motor draws power from six motorcycle batteries, recharges them via back-EMF harvested in secondary windings, and claims to achieve efficiencies up to 82 % (with future versions projected >100 %). The design emphasizes plastic and wood components to avoid magnetic interference and to keep costs low.",
    "detailed_description": "The motor consists of two rotors each carrying a permanent magnet, a stator with electromagnets, a shaft-position sensor, and a switch that energizes the electromagnets at precise rotor positions. As the rotor spins, the magnetic field compression between the permanent magnets and electromagnets generates torque. Secondary windings capture the back-EMF generated during compression and store it in capacitors to recharge the batteries. When the motor exceeds a certain speed the shaft rides on a magnetic cushion, eliminating mechanical bearings. Prototypes have been built in a plastic case (small) and a larger metal-frame version installed in a 1951 Ford pickup. Reported performance includes 10 000 rpm (small prototype), 15 000 rpm (wooden prototype), up to 600 HP and 5 000 VAC for a 15 x 30-inch model, and a claim of >100 % efficiency in future designs.",

        "The prototype EME has been shown to be up to 82 percent efficient, he said.",
        "Wheeler said he's run the little motor for an hour and only used 2 percent of the battery power.",
        "They expect their next prototype could be over 100% efficient, harnessing permanent magnet power which may be drawing it from some kind of universal energy source that nature provides inexhaustibly and for free.",
        "When the motor runs above a certain speed, the shaft rides on a magnetic cushion, not on bearings, eliminating the metal-on-metal wear all together.",
        "The motor produces no heat but runs at ambient temperature, so super-cheap, recycled materials could be used in its manufacturing."
