    Whose math is that? Initial minus final = 74V - 73.9V = 0.1V drop = 100mV less than what he started with. What is "1 mV? What is 99%? Nothing recharged. The 74 & 73.9V must be battery open circuit potential figures. During the wheel spinning the meter was reading 67.7V. Note 67.7V is less than battery open circuit voltage (74V), so the battery is discharging at 10.4A. So for his 16 minute air ride he used about 3 Ah. If it had a 30 Ah battery, then 10% of the charge was consumed spinning the wheel in air. Zero kilometers traveled. All energy was wasted. No recharge occurred.

    However the ideal combination of ReGen-X Quantum Motor coils and ReGenX Generator coils produced a solid 16 minutes of continuous running at 29 km/hr and the battery voltage did not drop and stayed at 67 Volts and it looked like it was going to increase to 68 Volts.
    It took me 10 minutes of waiting to see what the battery voltage would do before I realized I ought to pick up the video camera and record what was going on...
    BS. It was not "running at 29 km/hr". It was stationary. Zero km/hr. And he switched meter scales midway thru the 6 minutes to show 3 significant digits. During the last half of the vid you can see the meter reading fall from 67.7 down to 67.5V. A few 67.4 figures flicker towards the end.

    Why doesn't he put it on the road. It's only been like what? 4 years? Or at minimum, put the rear wheel on a load Dyno to get realistic load currents. And get some reasonable travel speeds. Who wants a 29km/hr motorbike?

    But I guess that is the point. Thane, like Turion will never do a legitimate public test because they both know they've got nothing but lies.

    Fake news BroMickeyLier:

    In the 6 minutes of the video, the battery goes down from 67.0 to 66.5V. And the 10.5A on the amp meter is the charging current to the battery. Thanes conveniently doesn't measure what the current from the battery to the motor is. This is a very easy measurement to do and should immediately show if the battery charges or discharges overall.

    And btw this is an old video that was already commented on extensively by bistander and myself.

    Happy New Year. Hopefully next year you will post some true stories. Have you considered going to work for the fake media?

    " so to work the homopolar generator the magnets must remain fixed or turn with the copper disk?"
    Yes.

    First you need to generate voltage. Requires complete flux coverage, uniform and unidirectional, over copper disc.

    To get high current, you need very low resistance electric circuit. Carbon brushes offer too high resistance. Use very low resistance everywhere. Brushes especially. Try straight copper metal at first. Will be low resistance but poor wear. Once working look into high copper content metal graphite brushes.

    Hi Memphis,
    Yep, with those set-ups you make an eddy current brake. To get the unipolar (or homopolar) DC generator you need a 'uniform' magnetic field covering the entire disc area.

    That's a pretty neat 12 pole synchronous PMAC dynamo. Memphis is working with a Faraday disc, homopolar, DC dynamo. Note the multipolar unit rotates the magnets adjacent to the stationary copper disc. Memphis rotates both the magnets and copper disc, essentially having no stator, except for the brushes.

    Faraday's Paradox. Interesting. Look it up.

    Bro, from the video it seems to me that the meter is set to amps, it is only 0.5A

    thanks Bistander, the magnets are arranged to attract each other, NS NS NS with the 2.5mm thick copper disc in the middle, I tried to rotate the disc at both 1400rpm and 2800rpm, but the result is almost the same , the increase is minimal.

    good morning guys, sorry if I allow myself, I know that this is another question, but I wanted to hear your opinion about it .... I tried to replicate homopolar generator, I used a copper disk with a diameter of 33cm, and 6 cylindrical 52n rare earth magnets measuring 6cm x 3cm, mounted in pairs on both sides of the disc and inserted in those nylons plates that you see in the photos to keep them united and integral with the disc of rotating copper, I turned it into rotation at 2800 rpm, I used 4 carbon brushes on the 2 inch diameter copper shaft and 4 brushes on the periphery of the disc, but the result was very disappointing, as you can see from the photos , not only the very low voltage, but the serious thing is that the amps were almost non-existent, we are talking about 0.2-0.3 amps ..... why? does anyone have an opinion about it or should I conclude that it is another fake ....?
    Hi Memphis,
    interesting project. Nice prototype.

    Are your magnets arranged unipolar or N-S-N-S-N-S around the disc? How thick is the disc? Air gap (distance between magnet faces)?

    Describe the brushes please. Where did they come from?
