I'm experimenting with new/different solenoids, coils that are now 216uH (in AIR), single-wire connection between tanks with bridge rectifier on either side, and connecting the solenoid center tap to one of the cans.

  • Further to my comments here, I can't help but think that Hendershot's intuition was far in advance of the supposedly educated experts who gave themselves the right to judge his inventions; eg the claw rotor.

    In notes I read yesterday I saw he used 'vibrating' pins/ blades for tuning purposes. Did his 'buzzer' armature have a 60Hz vibration mode under influence of combined magnetic field and coils, in the same way as resonant discs later used in Mechanical Intermediate Frequency Transformers?

    My humble attempts at replicating only PART of the full Hendershot circuit made me realize immediately that Hendershot was very experienced with coil winding -- as would be someone who tinkered with home-brew radio equipment. He utilized basket weave coils at a very early date. He was certainly reading up on what the main-stream was doing with radio at the time. His circuit has a heterodyne tickler coil -like - appearance. This was in vogue in the early days of amplified radio.

    Last night I concluded Hendershot '3' generators were a deliberate hoax.

    As with Hubbard's, only one method of operation was/is possible;

    this relates to something he possessed which he did not tell anyone about -

    because he was fabricating a story to hide the Truth -

    'free energy' has willfully been denied to us by the Governments for over 100 years.

    Was Hendershot going to 'tell' before his*official* 'suicide' ?

    He had access to military grade materials (magnet) and SUBSTANCES !

  • @z1zaz

    I had read some speculation about his unusual magnet... that it was out of some used military RADAR equipment ... and there was some speculation that the MAGNET had "accidental" properties. There was also speculation that both Hubbard and perhaps Hendershot used radium or some other radio active material to make the coils sing. Remember, though, that Hendershot made a TOY plane WAY before his fuel-less generator and if it likely worked on the same principal which I doubt was radioactive.

  • @z1zaz

    Good thoughts about close-to 60Hz for his circuit. I've reasoned that because of its mechanical nature, the resonant frequency MUST be low ... from say 50Hz upwards to 200Hz... No higher. For best POWER, you need to have a resonant frequency down low .. implying resistance is low, and inductance is very large. Hendershot appears to put all his inductances in series... which is interesting.

  • Hi morpher,

    Did you ever do more work on the Hendershot Generator ?

    I just read up on Mark Hendershot's notes.

    The magnet 6:10 was double south pole, north in the middle, could be fabricated using steel bar and neodi magnets.

    The soft iron stator bar was not on the magnet but vibrated.

    Wonder, was the magnet making the stator coils saturable reactors ?

    Wonder what happened that an antenna was no longer connected ?

    I recon the steel tube for the capacitor needed to be very close to the coil wind.

  • @z1zaz

    I think the cylinders might serve as antenna. Yes these tolerances such as how close the cylinder needs

    to be to the coil are things that need to be investigated. I have proven to myself that capacitors and coils can exchange A/C currents no problem. A/C or pulses travel through capacitors as if they were wires, so a cap can be incorporated into a transformer design.

see all

    When two magnets are glued face to face in opposition, then a coil overwind can steer the resulting field and modify that present at the junction.

    A sudden release of current causes the bulge of opposing fields at the join to 'ping' outwards at right angles to the overwind with extreme high field change speed !!!!!

  • @morpher44

    Surely that magnet would have been a military secret in the 50's?

    This is why I think the Mk3s could have been a radium type hoax.

    Yes he perfected the Mk1 before he was bought off, also he allowed his family to operate it.

    The Mk1 had an EM radiation collector/ initiator, but detail appears to be lacking relating to the encapsulated mechano-magnetic driver inside the initial wave-wound coil.

    Did that include a Radium or Pitchblend based internal fixative to stimulate photon release?

  • @morpher44

    I read his series connected 'buzzer' coils were separately measured at 5.6mH and 10.5 ohm each in the Mk3 cct.

    11.2mH and 40uF brings us close to 200Hz; then add in the other series connected inductances, incuding other transformers !

    Also his original Mk1 cct had a single untuned wavewound coil assembly, though with 2 close coupled two turn overwindings likely having high distributed self capacitance.

  • @z1zaz

    From trials of ferrite sleeve antennas like the new FS Loop design (google), I have observed considerable alternating magnetic field interaction with ambient at mv/m field strength transduction, so H's field interaction with Earth-Space field at 100W plus of power, must have been considerable - same with Hubbard and Moray.

    I wonder if the 'buzzer' is saturation 'switching' output power from alternately induced parasitic ringing events within otherwise spatially synchronised steel cores ?

  • @morpher44

    An observer stated the cylinders would attract a magnet, but were non-(para)magnetic.

    ie, the internal molecular electron orbit spins could align with magnetic inducement yet return to random.

    .

    I think of the tuned winding induced electron aligment oscillating throughout the ferric sleeve was longitudinally disturbing the spatial magnetic equillibrium via electron orbits within the steel being made to coherently precess in a wave like motion wrt the winding.
