    "goal": "Investigate whether a small, inexpensive ceramic-magnet generator can produce self-acceleration, weight-change or other free-energy effects described for the full-size Searl Effect Generator.",
    "problem_addressed": "The claim that rotating permanent magnets can extract energy from the environment (ether) and produce net power output, a phenomenon commonly referred to as the Searl Effect.",
    "concept_summary": "A cylindrical stainless-steel housing contains a vertically magnetized ceramic rotor magnet (cobalt-samarium) surrounded by twelve ceramic magnetic rollers. The rollers are initially attracted to the rotor and then spaced by mutual repulsion. During motor-driven rotation the rollers are expected to self-accelerate and reduce the motor's power consumption, indicating energy extraction from the surrounding medium. The prototype was instrumented with optical and inductive sensors to record rotor and roller speeds, motor current, and temperature.",

        "After the speed reaches a particular value of 8.5 rps, the speed of the rollers stabilizes and does not increase in spite of the increase of rotation speed of the rotor magnet.",
        "Unfortunately, we couldn't find any anomalies in the temperature distribution and distribution of magnetic field around the converter.",
        "These experiments proved the point of view that during the device operation the nonlinearity of the wave processes, which take place in quantum medium (ether) plays the main role."
