["Dr.Hankenstein" <dr.hankenstein@xxxxxxxxxxxxx>]

Very interesting work you're doing here, Harvey. I'm still trying to digest
the theory. As always, it is nice to see someone working in virgin
territory. Please keep us posted on you progress.

Thanks,
Hank

It can be shown and argued by voltage and amperage measurements that the
alternator can input more energy to the TC then the 60hz 15,000 volt/ 30 ma
NST, and this is quite unexpected to say the least since only one of three
phases of the AC alternator are utilized. The 456 hz TC utilizes a smaller
primary and 2.5 times the capacity the the NST design utilizes.
>
> In the alternator/pole pig connection I have procured a special situation
whereby the capacitance employed in the TC primary is reflected through the
pole pig primary connection to the alternator stator windings so as to
resonate producing two useful effects, but first the understanding of the
principle of maximum energy transfer is noted, so that the comparison of
actual currents and voltages can be compared to this theory of maximum
energy transfer. Generally speaking the two specifications noting the
ability of the source of emf to produce power are given; these are the open
circuit voltage without a load attached, and the current that source can
deliver when a short is applied. What the maximum energy transfer theorem
implies is that when the open circuit voltage is cut in half by the amount
of load attached, this is the point of maximum energy transfer, but in this
situation only half of the short rating of available amperage conduction is
> available. Thus the maximum power or voltage times amperage from the
source is actually each of these ratings cut in half and then multiplied
together, yielding one quarter of what would be available if the power
ratings of open circuit voltage and short measurement of amperage were
simply multiplied together. Thus this maximum power output of the NST
should be [15,000 V* .03A]/4 = 112.5 watts. Now the same procedure is
applied to the alternator phase as a source of power. Because of the fact
that the pole face field rotor becomes remanently magnetized,( in the
correct polarity determined by its spin), the moment the alternator is
turned on these voltage and amperage ratings become apparent. All three
phases then read 1.6 -1.7 volts and a short of one of the phases shows a
delivery of 1.35 A. Now the pole pig is attached to one of the phases with
the addition of an amperage meter set on its highest scale without the
secondary load of the TC primary
> attached. This one threw me a loop because on the testing of two
different higher voltage transformers, both amperage readings of the non
loaded primary read 0 Amps. Apparently the open secondary condition of the
pole pig transformer that determines the highest impedance of the primary
has a non-linear response to the increase of frequency, where here the
increase in frequency being 7.6 fold would mean 7.6 times less primary
amperage conduction to the unloaded pole pig primary, but that may not be
happening and later the actual ratio of expected currents vs derived
currents can be calculated to show the non-linear increase of impedance
with increased frequency. This has been noted before with the stolen high
induction air core coils that exhibited 60 henry at 60 hz, but exhibited
values near 200 henry at these frequencies.
>
> Now the first attempt of showing an alternator powered TC involved first
making one at 60 hz powered by the NST, and that also was problematic but
we arrived at a hit/miss solution with a 2 ft secondary with a larger top
capacity that improved performance so as to exhibit 4 inch arcing. This
model uses 20 nf capacity. When the alternator/pole pig combination was
substituted as the power source the same coil only delivered 1 inch arcing,
but even this was a first. Jumping the gun a bit, the alternator/ pole pig
power source was reexamined to see if the capacity in the TC primary was
near the maximum energy transfer point. A turn on of the alternator yielded
3 phases of 1.6 volts before the field is energized, where the middle phase
2 is selected for the pole pig. As mentioned no amperage is recorded into
the pole pig primary until the secondary capacitive load of the TC primary
is added. With the arc gap separated and the field non- energized a series
of
> amperage conduction and voltage output tests are made. The short as
mentioned yields 1.35 A of a single phase, and an open circuit value of 1.6
volts. When the TC primary value of 20 nf was added to the pole pig
secondary its primary amperage went from 0 to .66 A, but the source voltage
of 1.6 Volts did not decrease its value to half, which is what a purely
resistive load should do by the premises of the maximum energy transfer
theorem, where it is assumed that having reached half of the short value of
conduction will also reduce the source voltage by half. Instead what
happens is that the stator voltage is increased by one third to 2.2 volts.
So initially measuring things on the high voltage end for these
circumstances, and also considering that since such low voltages are being
employed non-linearities of voltage transformation may exist since this is
the very low end of the saturation curve of the transformer, but
nevertheless the first recording of
> output voltages showed 123.5 volts without the capacity attached and 184
volts when it is attached. Now all these measurements and comparisons of
ratios seem to become distorted from their initially measured values at
this lowest possible level of measurement conducted with an un-energized
field, and these differences can be shown in comparison at real operation
with an energized field with a 10 Amp pole pig primary consumption, and
after the TC had been redesigned to employ the nearest correct resonant
secondary capacity to be determined by these unenergized field tests to be
noted next. In that case after the TC primary was redesigned and the
correct C value used, it was noted that by sending a third of an amp
through the field, this created three phases of 7.1 volts with no load
attached, but then attaching the TC primary to the pole pig secondary
resulted in the primary stator voltage now going up 60 % to 11.5 volts.
Thus at only a 7 volt unloaded
> stator it becomes 11.5 volts conducting 10 amps into the pole pig
primary, and the alternator can be pressed to do triple this duty for short
periods of time, sending near 30 amps into the pole pig primary.
>
> Now getting back to the un-energized field tests, the next thing to be
explored was the value of primary amperage consumption once the registered
level of 184 volts at the pole pig secondary was shorted, and this yielded
only a 1 amp primary consumption, when in fact a direct short of the stator
lines connected to the current limited supply of the alternator yielded
1.35 A. This at first puzzled me so then obviously the next thing to do was
to try various values of capacity for a pole pig secondary load. The
capacities being used are a series string of five .1 uf values yeilding 20
nf. Taking one out of the string yields 25 nf, two taken out yeilds 33nf,
and next a value of 50 nf. Note how the adjacent stator phase voltages
having no load are influenced by phase 2's pole pig primary load.

Using 33 nf; Stator phase 1) 1.5 volts Stator phase 2) 2.8 volts yields
1.55 A primary draw, it has exceeded its short value of 1.35A and also
yielding 253 volts at arc bars Stator phase 3) 2.5 volts

> Using 50 nf; This begins to load down stator phase 1, which along with
phase 3 is unloaded, so we wonder why the dramatic loss here on phase 1
which gets now get reduced to what the rms voltage meter interprets as 0.7
volts and now some scopings are made of the phase angle differences between
the affected phases. Initially it is assumed that the 3 phase alternator
distributes three maximum voltages 120 degrees out of phase and an unloaded
scoping of phases 2 and 3 as a dual channel scoping shows this fact, but
first the proper procedure for making these scope observations is noted.
First an isolated ground for the scope itself is desired which is enabled
by using a 2 prong plug into the wall voltage instead of three prong plug
for the oscilloscope which is simply achieved by use of a two prong
adapter. Now it is also observed that the common ground connection between
the scope leads themselves is in fact a common ground point, except for
perhaps very
> expensive scopes having dual isolated grounds on each channel. What this
means is that the first channel to be scoped uses both the probe ending and
the smaller clip as the ground. But the second channel when added only uses
the probe lead, and its ground connection is left open. The attachments for
the measurement of the adjacent phase once the first two connections are
made must be referenced to the placement of the ground clip on the initial
connection, which becomes channel 1 making a voltage measurement of phase
2. The alternator delta output has three points of voltage delivery, and to
reference the phase 2's primary connection to be loaded by the pole pig
secondary load of 50 nf, to the phase 3 which also sees a voltage rise from
phase 2's reactive loading, the common ground clip of the first channel is
made to be the point of delivery on the delta stator where both phase 2 and
3 have in common, and channel 2's probe lead is given the remaining
> delta point not yet attached with its common ground lead unattached. In
other words the common ground leads must not be shorted in making the dual
channel scoping observations, and since there are three points of voltage
reference and four points available to make these voltage reference
observations, one of the common leads must be omitted. To reference phase 2
and 3 the common ground of only one channel is placed on the delta triangle
on the point where the phases themselves are in common, and thus to measure
the referenced voltage between the other combination of phases 1 and 2 the
common lead is changed to the point in common on the delta triangle that
the measured phases themselves have in common. The first two dual channel
scopings are referenced between phases 2 and 3, both of which receive a
voltage rise after phase 2's addition of the pole pig primary load.

increase in the alternator established current limitation and 262 volts at

measurement of the actual current that should ensue for a 50 nf capacitive
reactance at 456 hz having an ohmic resistance of 6984 ohms @ 262 volts
however shows that these values are in agreement with current meter
readingsof 37.5 ma on the secondary end, and it is seen that although the
voltage rise ratio has been expanded, the current ratio of primary amperage
consumption and secondary amperage output has been preserved at 64/1. Note
here also that the open circuit voltage vs capacitively loaded operating
voltage has been increased some 60 %/ in reference to the previous dual
channel scoping

initially incomprehensible. EVIDENTLY THE THREE FOLD DIVISION OF VOLTAGE
REFERENCE POINTS IN TIME DELIVERED BY THE THREE PHASE WYE CONNECTED STATOR
WINDINGS PRODUCING A DELTA OUTPUT CAN BE ALTERED IN TIME THEMSELVES! As an
apparent result of this the voltage normally available on phase 1 has been
robbed from to provide an excess of voltage on its adjacent phases, where
its rms voltage reading shows only .7 volts. We might expect that since the
timings of voltage delivery have been brought near 180 degrees between
phases 2 and 3, this leaves very little phase angle difference left in 360
degrees of total time available between cycles on phase 1 which we then
term a â??neutrallyâ?? timed phase because of its loss of voltage; however
we still wish to investigate this timing issue by making a scoping to be
made

made at 2/volts/div. Because of this waveform shape the phasing angle
difference of the adjacent phase is hard to determine, but we would
certainly expect that the peaks of each waveform should co-incide better.
In fact the smaller dual peaked portion of phase 1's waveform does this,
but its larger one peaking at some 1.8 volts appears in the timing
reference point when the adjacent phase is producing 2 volts in opposite
polarity!??. .. Thus here the presentation of an incredible premise can be
made;

> THE CREATION OF THREE OPPOSITES IN TIME.

> What I have just shown is two oppositely phased voltages whose highest
peaks deliver almost opposite polarities in time, thus the net difference
between the voltages is almost the sum of their individual voltages. Next I
showed the voltage reference points to the neutral phasing showing that the
adjacent phase voltage can still have better then an equal and opposite
simultaneously created voltage in time. I have also been able use pancake
coils positioned in space at certain angles to each other to interact to
show an impossible phase angle greater then 180 degrees as we define it, in
that the net difference between the individual voltages in time is greater
then the sum of these quantities, but this issue has not been scoped out
yet to see what nuances of waveforms may exist there. Again the analogy of
dimensional progression is applied here. A two dimensional flat equilateral
triangle has three internal 60 degree angles, adding to 180. If we instead
> expand the internal area of this triangle by superimposing it on the 3-D
curvature of a sphere, we find that now the individual angles become
greater then the sum adding to 180, according to the ratio of the triangles
internal area vs the total surface area of the sphere. If we just use a
small portion of the sphere's surface area for the triangle the internal
angle change is negligible, but if the triangle is expanded to encompass
1/8th of the total surface area of the sphere, its internal 60 degree angle
will have increased 50% to 90 degrees. Now the analogy becomes expanding
the three 120 degree phase angles in time 50 % greater to that of three 180
phase angles in time. Somehow we presume that now a 4th dimensional
coordinate has been added, with the result that time has been expanded, and
a circle in time of phase angle differences no longer adds to 360 degrees,
but in excess to that. A 440 degree phasing measurement is shown at

application with three identical TC's powered by a three phase high voltage
transformer, which is also at my disposal for these experiments.

NST vs pole pig/alternator combo. We might assume that 32 volts input
becomes 62 fold through the pole pig transformer becomes near 2000 volts so
the ratio to 15,000 volts would be 13 %. But then again this amount of
energy transfers 7.6 times faster at 456 hz and multiplying .13 by 7.6
yields the original amount. But since the V term is exponential it would
seem that 60 hz @ 15,000 volts should have more energy transfer, however it
may be true that since the 20 nf value being used is over four times the
rated current limitation of the NST secondary, that it may only charge
those caps to 1/4 of its 15,000 voltage rating? And additionally the value
of capacity used for the alternator pole pig combination is 2.5 times
higher at 50 nf, which the NST may not even be able to fire. In any case I
have made my argument that that alternator can out-power the NST with the
456 hz driven TC
