Hubbard coil

[giantkiller]

And getting back to simplicity with air core the coils can emit the field more freely and farther into space. No dampening. Only one material by one frequency to resonant. Add another material and you don't get the single tune.

Yes, core material is a major concern.  Having uniform cores made from exactly the same material are also key.  I am thinking about small wires, like 1 mm (0.0254 inch) wires that are laminated and grouped into rods. Then the windings are wound directly on the conglomeration of iron rods.

The resonant frequency of the core is defined by the permeability of the cores.  This thing needs to be compatible with current equipmentation.  This means a relatively low frequency.  Most landlocked equipment is 60 Hertz, while ship and aircraft are 400 Hertz.  We are supposed to build a compatible power supply, not something that resonates in the KHz band.  So the large amounts of iron in the cores gives it a relatively large permeability.  The Hubbard Coil is a current generator and not a HV generator.  The iron slows down the resonant frequency to some thing below 500 Hertz.  The actual frequency is dependent on the physical coil design.

I really had to bend my reality to understand this thing.

Howdy Grumpy,

You have to look at this thing in a different way...

Tesla defined alternating current theory, and I have seen it resonate with a sinewave.  The reason that the ring oscillator will work is not magnetic induction alone.  The wave running the peripheral coils is "pulsating" via alternating current.  The magnetic fields are spinning around the central core.  This produces a vortex in the center coil, increasing the flux density and increasing the energy traversing the coil.  Ordinarily the back EMF from a coil is less than the initial energy put into it.  But in this case the vortex produced by the spinning magnetic coil pulls more energy in from the surrounding environment.  This produces a power gain in the center coil which is inductively coupled to the peripheral coils.  This increases the voltage in the peripheral coils, sustaining the device.  The core design is the key to the magnetic vortex.

I am looking at this from a realistic perspective not some damn la-la-land-pseudo-magentic-vortex-sci-fi-wanna-be way.   Hubbard never said it was AC - he said it "pulsated" and that is a huge clue that you choose to ignore out of ignorance!

If there was a magnetic vortex in the center coil - in the orientation illustrated - it is not perpendicular to the wires and therefore can not induce an electric field!

If HV is not required to excite the device then why the 11.25 kv DC power supply?!  Why the auto distributor?  This device does not work by the application of high current!  It can't!

If you had any idea what I gave you when I explained this device, your mind would melt, so perhaps it is best that you didn't "get it".

Believe whatever you want, be as foolish as you want, enjoy your "blue pill" and your self-satisfying world of illusion...

now your all gonna get me going agin ....

you dont need me have a look at this thing .....

do ya??

i have never even looked at this thing but i can tell you this i can figure it out too !!

why?

cuz someone else already did...  if 1 can we all can ....

think simple....  it is the best way...

ist

gotta be plused dc ....

........So, the hammer and the tuning fork are separate and that is what Tesla was doing.  The resonant rise stuff was just a means to get a higher voltage.  He stated much later when that resonant rise was not the best way to achieve this........

That is really interesting, as I have read tons of Tesla's works, both early and late, and have never come across this assertion. It would be great if you could provide a source for this Grumpy sir.

Concerning the impact resonance, yes self-limiting resonance is achieved. However, this resonance is self destructive, and doesn't provide squat.

ADDED CONCERNING ABOVE STATEMENT:
Otherwise every single resonant frequency circuit built would be producing the desired effects...... Radio's, TV's, Computers, etc.... Yet, they amazingly DON'T.
END OF ADDITION:

It is amazing how everyone states the TPU puts out DC.

In the video copy I bought from JDO300 (the high-quality version), it is amazing how he makes the statement DC at 5Khz, then when prompted quickly states "No, it is A.C... For all intents and purposes it is D.C."
