What's going on here in this Hob Nire video? "Harmonic Resonance":

The same thing is going on as has been used in RF equipment for many decades:  A waveform with lots of harmonics is used to stimulate a resonant tank that has been tuned to one of the harmonics.

@MarkE,


Thank you. It dosen't appear as though Hob's powering his Bedini with the oscillation.


The precision ceramic bearing in the top photo is 1/8" ID and 1/4 OD. This bearing slips over the 1/8" brass axle in the photo below, and the 1/4" ID magnet tube slides over the bearing. This "thick walled" PVC coupling allows for safe shatter proof spinning at Mach level RPM. The axle is stationary!


This thick PVC "Coupling" safety shield is the best protection against magnet shattering I've seen devised, and absolutely essential for high speed RPM. Done this way, it's a very exciting kind of of fun and completely safe. That's all it takes to spin up to LC harmonic range safely! The precision ceramic bearing costs are the only prohibitive aspect of this kind of platform at around $75. This setup was designed by me especially for safety! It's possible to cap both ends of the coupling, and cut a small slit across one side to laser tach through. Starting can be accomplished by magnet swipe from outside.


This design allows us to evacuate the housing with a plexiglass tach window in place if we choose. I inserted a plastic sleeve through the tube magnet in the bottom photo that extends from both sides, to help visualize the size of the bearings.

Here's a better picture of the bearings, and a link to the manufacturer:

I viewed the "Tuning Bifilar Tank" video by the "Old Scientist", and he concluded that the bifilar tank needs capacitive resonance.  The Reed Switch capacitance of .2 pico farads must have matched the self capacitance of the tiny thread spool air core solenoid bifilar in my prototype. I really need to test the coil, but the math holds up.


Take a good look at this "Resonance of a Bifilar Coil" video if you haven't already seen it: "While in resonance we are able to capture the reactive energy into the inductance of the ferrite, lighting the led without affecting amperage".

We can capture reactive energy from the oscillating sine wave in the "Bifilar Coil" to power a "Magnet Spinner" in resonance without affecting amperage too. A tiny axle and bearing disk spinner mounted inside the 100 hertz resonating  bifilar coil core, spun up to 6000 R.P.M. let's say by compressed air , should start to spin with the same reactive power that lights the LED.

I think that you mean reactance.

When you can add a load without affecting the input, it invariably means that you are shunting power away from another loss mechanism.  The analogy is idling your car in Drive and controlling your speed with the brake.

@MarkE,


"I believe you meant reactance"


No, I didn't mean "Capacitive Reactance", I meant what I said when I said resonance LCC. When we wire a capacitor to a series bifilar, we basicly have two capacitors in the Tank. The external capacitance can either be in "Harmonic Resonance" with the self capacitance, or dissonant! 


Here's what "The Old Scientist" had to say about it:


"Bifilar coil has strong harmonics, but it's not influenced in the same way a standsrd or series LC circuit would work by achieving resonance between the capacitor and the self capacitance of the coil".


Try to understand what he's saying: The external capacitor can not be tailored to the biflar tank in the standard way!



What do you make of TK's sine wave spinner that acts as a "Negative Load" in regards to your views on power shunting? Think about this; How much input do you think the spinner would feed back into the tank?

Synchro, I've shown the effect of no change in input with an added load many times. It is as Mark says, it's a re-routing of
losses to the load. What do you think is happening to the input when there is no load and the input is still the same as with
a load ? I'll tell you it's wasted. So all that wasted power would need to be made up before tipping the scales anyway.

I can show a decrease in input with an added load, I can show no change to the input with an added load and I can show
increased input with an added load, and I can do all those things without a series connected bifilar wound coil in sight.

The effect has nothing to do with bifilar wound then series connected coils. I can prove that and have done already.

Look, I do not care any more that you are misrepresenting and misinterpreting Tesla's work as well as common electrical parameters and relationships

BUT STOP MISREPRESENTING MY WORK !!

I have asked you MANY TIMES to stop misrepresenting me and my work but STILL YOU CONTINUE TO DO IT.

Well then you are just mistaken.  There is no such thing as "capacitive resonance".    In the realm of lumped elements, resonance occurs where the capacitive and inductive reactances are equal.

There are only two possibilities in this world:  One has OU or one does not.  Since no one has successfully proven OU, under the assumption that a circuit is UU, when load changes do not reflect to the source, it is because the load simply shunts power that was already being drawn from the source.

@MarkE,


Here's what I'm talking about: The Colpitts uses the twin capacitors. Tank resonance drops when the twin caps are connected, because half the electrostatic energy disappears. The twin capacitors also stabilize the resulting tank frequency. The halving is a consequence of connecting wire resistance.


The series bifilar connected to an external capacitor equal in value to the bifilar's self capacitance halves the electrostatic energy, and lowers the tank frequency. The bifilar inductor and the twin capacitors oscillate at lower resonant frequency. It's not wrong to describe the two capacitors as in capacitive resonance with the inductor.

Synchro, you say Colpitts, but you've attached a picture that describes the conservation of charge versus conservation of energy problem charging an empty cap from a charged cap.  A Colpitts oscillator has two capacitors, but it also has an inductor.  As long as we are in frequency regimes where we treat capacitance as lumped, we need an inductance to build a tank.

That's what I just got through saying. The important point is that if the Reed Switch goes normally open from excessively high magnet rotor speed and begins to act as part of a colpitts tank circuit, the self resonating frequency of the bifilar tank drops!

Synchro I don't want to degenerate into pedantry, but technical terms have specific meanings.  An LC tank circuit resonates.  Ignoring parasitics, neither the individual capacitor(s) resonate.   There is not a capacitive resonance or an inductive resonance.  There is just a resonant frequency where XC = XL.
