Original TCML Post
- Kind of funny here, Paul Nicholson made a rare reply to TCML, so I sent this to him and CC'd TCML as a second recipient. This meant that if TCML again refused the post, at least Paul would know that. So After 6 months, TCML finally agreed to show my works.
First here is a preliminary reply;

This kind of work is on the fringe of TC coiling, and definitely not for beginers. In fact most will see it as being impractical. Indeed to reproduce these kind of effects using 3 phase from the power grid @ 60 hz would be problematic if not impossible. But many coilers have wondered if any advantages might be procured by using a higher frequency input,(near 500 hz) that a AC car alternator can provide. I use two high voltage 100 nf,(.1 uf) caps in series for my primary C value(s). This equates to 50 nf. Using slightly larger pulley diameters from the motor 3450rpm to the alternator pulley will provide a freq. from the 7 pole face alternator; (7 cycles / rotation) of about 465 hz. Under these conditions for a given field input, let us measure how much amperage the alternator can supply on a dead short of one of the three phases, and note that value which would normally be considered as a LIMIT as to how much amperage the alternator will deliver for the
specified DC field amperage conditions. Now let us replace that output short with a pole pig primary connection to this 64/1 step up transformer whose secondary now has that 50 nf load. What I found was that now the alternator phase delivering amperage had increased 80% past what the short value showed itself to be. This is a ferromagnetic resonance similar to what happens when a NST is given a capacity that matches the inductive reactance of its secondary. Ordinarily that practice is avoided with NST's because with a 120 volt input, the output of the NST would be over volted and damage the transformer. But here because the pole pig is practically indestructable, and also because the alternator normally only outputs a meager voltage in the 15 volt range, we can utilyze that ferromagnetic resonance principle. The worry about ballasting the pole pig transformer primary is replaced with the worry about the current limitations of the alternator itself,
which shouldn't be to hard to ruin with heats involved when that alternator begins producing more amperage then it is designed to output, given the limitations of that source to provide amperage.
So all of these things were noted years ago with the first alternator powered TC that actually only provided 2 inch secondary top terminal arcing. The car alternator simply cannot compete with the amount of power that the conventional 60 hz power grid can deliver. I mention these things as a primer to those interested in car alternator TC's. What has transpired beyond that point is quite beyond the scope of discussion for tesla coils, and involved the use of large inductors that could also resonate with that 50 nf C value at the alternator freq, and was more involved with the study of source frequency resonances, which is a totally different ballgame then the more familiar high frequency arc gap tesla secondary resonant phenomenon. Because I had extensively studied the source frequency resonant phenomenon both at 60 hz and the higher alternator frequencies beforehand; eventually I was able to connect these phenomenon in a somewhat unique way after first
building a 250,000 hz TC powered by an NST @ 60 hz. To connect these phenomenon I merely changed both the primary winding amount and changed the C value to the noted 50 nf so that both the source frequency and arc gap high frequency processes could be compatible. It was in this way that the use of ferromagnetic transformers at alternator frequencies could largely be bypassed. I thank the moderators of TMCL for allowing me to introduce this subject, and hope that I was not rude in doing so.

3 phase Car Alternator WIRELESS Bipolar TC

3 phase WIRELESS Bipolar TC system
At (3 ph) AC car alternator freq of 465 hz; a SOURCE FREQ series resonance can be established where by using a very large air core inductance, (2.4 H) the power transfer above and below sandwiched (pancake spirals obtained from 3 phase),(266 primary system) can be attained to itself power two primary arc gaps. This makes the operation of the TC system a COMPLETELY wireless operation. Even though this system is obviously a new type of tesla coil system, TCML refuses to allow posts concerning the subject, saying they do not discuss subjects on wireless power; they are off topic? The thing that makes these things work is that the source freq C value @ 465 hz will be the same C value that the tesla tank primary uses. No ferromagnetic transformers are used to power the primaries, instead the series resonant rise of voltage is used.
Comparison of Secondary Amperages
The secondaries have a reactance of ~7000 ohms at this 465 hz alternator freq., so for every 1 ma of secondary amperage circulation, 7 volts will be across the coils. In this demo the amperages of secondary and primary for top and bottom are noted.
Independent Dual Secondary Loadings of 266 primaries
The top secondary empowers three incandescent bulbs in series@ 490 volts
enabling 40 ma across load, from a 70 ma circulation. Its adjacent phase 3 pancake coil uses 4A @~10V. The bottom two phases 1 & 2 have ~1.5 A consumptions@ 10 volt range and above. The bottom secondary empowers a magnet assisted neon discharge whereby a wildly
fluxuating 5 ma is taken from a 40 ma bottom secondary amperage circulation or 40*7=280 volts,(the neon will not normally fire at this lower voltage and the use of the magnet is an innovation)
Bipolar Wireless TC
Dual Gap Firing
As indicated before getting both gaps to fire on the independent secondaries is problematic. Apparent by concurrent amperage readings of both the top and bottom secondaries the top secondary having the higher voltage will always fire on its gap first, sort of monopolysing the action and preventing the bottom gap from firing. The way the magnetic field action has shown itself is that if no output is taken from the bottom secondary, more magnetic field goes out the top secondary for interaction. But this allocation of magnetic field density
according to the recievers that are present does not work in reverse, probably because of the phase rotation. So what is desired in this operation is to have the weaker bottom side firing an arc gap, rather then the stronger side firing, and having no firing on the bottom. Now every time the bottom gap fires, it shorts out the higher currents on its LC loop, placing that amperage demand down to its lower reactive conduction; thus making for more magnetic field to issue to the top secondary. More secondary current will be attained to every time the
bottom secondary short arc gap fires. What is needed for the top secondary is to have a "weaker" arc gap, whereby adding resistance to the arc gap path was found beneficial, now this higher resistance pathway including an arc gap in series with the elements, this also means that "less" amperage conduction will be diverted through that top stronger LC loop: and when that systems gap fires, it probably doesnt reduce the short amperage to the components reactive value that
a direct short with associated TC primary in series normally approaches; where here we are also assuming that the primary arc gap itself has minimal resistance, which also may not be true. In any case by using this method, less amperage drop in secondary circulation during arcing must be occuring; and in this specific case the presence of amperage on phase 3 laying underneath the top secondary LC loop IS PREVENTED from assuming its full value; PROVIDED the top
secondary currents stay near their full value; where this method hopes to utilize that efficiency factor. The method uses a steel plate holding a ceramic magnet with a glass of water suspended below a needle, which then arcs to the water surface in a barely visible display. This method produces a very stable oscillation. It was then further found that the ordinary method of supplying a
directly shorted arc gap to the top secondary would also work simultaneous to the copper bar gap. This was done by taking the glass and magnet resistance out of the series by shorting then and then attaching the plate clip to the water itself, making this a simple water arc gap. So here we have two operations that
can be shown for you tube videos
Water Arc Gap for Top Secondary/ 1 inch TC Secondary Arcing
In this video the newer method for dual arc gaps is shown. The open circuit voltage of operation before the loads are added is shown. Surprisingly no significant drop of open circuit voltage after the circuit is engaged is noted.When the system is pressed for more continuous primary arcing neccessary to maintain a 1 inch secondary arc, the peculiarities of phases 2 & 3 voltage delivery going above their no load state is then noted, but with a sporiadic
primary arc gap this effect is not so evident, but still it would seem the delivery of amperage to the system should drop the voltage delivery down more then it appears to do. Now I am thinking the system needs a ferromagnetic transformer brought into the picture so that these voltage drops take place. Running the alternator with a projected 15 volt field as done in this video should produce about 28 volts open circuit operation: this should be coming very close to field saturation. This means the alternator should be getting hot
rather quickly and long duration runs at this level would not be advisable.

Conventional Arc Gap for Weak Bottom Secondary
Tests for 1 inch Top TC secondary arcing.
Improvement of Bipolar TC Demo.
As I was saying, sending 15 volts into the alternator field to produce a 28-30 volt stator level at this 465 hz rpm is an excessive amount close to projected field saturation. What was theorized and now demonstrated is that instead of having this high input voltage for the common operation of the alternator, we can instead introduce a ferromagnetic transformer between the source and its load. Since ph1; the bottom layer of the 266 primary system is primarily responsible for firing the arc gap from the weaker voltage present on the bottom
secondary; we introduce a 4/1 step up transformer between the stator lines, and then connect the former lines up to the transformer secondary. This practice seems to produce the same secondary 1 inch arcing set for tests; at only 2/3 the amount of field current.
A turn on today of 266 primary set up showed 147 volts from the top secondary and 100 volts on the bottom. After introduction of 4/1 step up transformer on bottom ph1, its input voltage went down upon secondary loading where the new conditions became 112 volts on top secondary and 180 volts on bottom secondary.
Thus the phase needed to fire the primary arc gap will now fire before the field currents and stator voltages become excessive.
4/1 Step Up Transformer added to bottom layer phase 1
The amperage meter for phase 1 remains on the phase itself; between the L and C quantities. However the primary of the transformer that feeds that phase should be drawing four times as much amperage by ratio. Thus phase 1 is actually being loaded down far more then the adjacent phases which employ no transformer. Because of this the stator voltage from the alternator serving phase 1 is reduced far below the other phases; and again those other phases exhibit a voltage input ABOVE the value they would exhibit if no load was present. The discrepancy of unequal amperage deliveries to phases is shown by the top stator line meters. A 10 volt field is used, rather then a 15 volt one as done in the
Graduated Input Parameters for Bipolar Wireless TC/ 4/1 Step Up Transformer Employed on Bottom ph. 1. By noting operation at 10,20 and 30 volts variac input to field,, the ratios of received currents for each phase can be compared. Ordinarily this ratio would be constant for a linear increase of power input. If it is not constant,torsional considerations may apply. This is undoubtably true with the flux
capacitor, the ratios of currents between resonances will not show a linear relationship upon increase of currents to those devices. This video may proove useful for making later comparisons, as the time for making good meter observations were made with good lighting. The action of the water arc gap for the top secondary is shown. Remarkably the coil using the weaker influences of the top secondary arc gap, and it's apparently weak water arc gap actually display the strongest influence on it's associated secondary column.
