I assume you might be refering to the 600 wind coil
multilayered coil where I noted that it resonated at
30,000 hz. In that situation there is no coupled
external capacity C,  In the analogy I merely used
this  coil construct and imagined how much bigger
diameter wise the same 600 winds  would have to be to
naturally resonate at 10 hz. Incidentally since
ordinary car size 3 phase alternators already have  7
pole faces ,only one rotation yeilds 7 hz. And
somewhat more remarkable the actions of an alternator
can be regulated with a self feedback loop of stator
AC output recycling output current back to the field
through a rectification obtained as a load from
resonant circuits placed on the alternator, thus
establishing a rpm dependent magneto effect, where the
alternator outputs power, but no  external field
currents are necessary, and this process is also rpm
dependent. What this means is that we could put an
alternator on a windmill, and it should be
freewheeling  until the rpm is reached where the
external circuits are then resonant at that rpm, and
then a recirculation of field currents occurs in a
controlled manner, where  experiments conducted with a
constant rpm source by a single phase motor driven
alternator, showed that just a direct stator/field
rectification feedback loop, without this resonant
ballasting will result in an uncontrolled chain
reaction between the stator output and field as a
runaway remagnetisation loop, bringing the alternator
very quickly into overload operation. Unfortunately
these effects are negotiated when the field rotor
already has an appreciable spin, where the feeble
magnetism created by metallic spin is amplified on the
feedback loop, so for this example making a 8 hz rpm
dependent magneto effect might proove unfeasible,
because of the low amount of field rotor spin,,, going
off topic here...

And there are special complications for resonating a
coil with internal capacity also, where in this
instance given the L value with C(int) when we add an
external C value, this seems to appear in series with
C(int), so that adding C(ext) and applying the
resonant formula does not yeild the predicted resonant
freq, we must consider the true C value as C(int) and
C(ext) in series.

Yes I did this with some 60 henry coils containing 9
miles of 23 gauge wire, using .12 uf C value, where
the 1000 ohm coil gave a q factor of 15, exhibiting a
voltage rise 15 times the input. The amazing thing
about the 60 hz resonant circuit is that I could light
a small radio shack neon from the system when the plug
was connected to a utility strip with the switch set
to off position. I think perhaps polar capacity
currents, or one ended currents with no return wire
are responsible for these currents that must come from
the grounded side of the circuit, and the off switch
evidently does not break that grounded connection
otherwise I would not be getting these one ended
currents. When the switch is actually turned on,
giving two opposite q voltage rises of 15 times 120
VAC; each bipolar 60hz resonant coil can light a 20
inch neon to ground , but not both simultaneously. If
one side was given a florescent to ground connection,
and a distant location given a neon path to ground,
the neon discharge could be controlled by allowing the
easier ground of the florescent to be enabled. Since
these are bipolar, or opposite voltage rises, if one
side were pumping electrons into the ground the other
side would be removing them. This provides for some
amuzing speculations as we might first measure the
supply of resonant voltage rise in open circuit; and
then consider the neon/ground path/ florescent pathway
as the load on that resonant potential, where if all
three of these elments were monitored for the voltage
drop, we might arrive at a ground resistance figure
calculation. The ground itself might just proove to be
a nonlinear resistance, which is evidenced in many
loads, such as water, neon tubes, ceramic magnets, and
even somewhat inconcievably the field of an
alternator. Even more amuzing is what happens for a
direct 20 inch neon grounded connection, with the coil
system directly hooked to a wall outlet, where the
neon bulb rapidly flickers where VHS tapings looked at
frame per frame showed about 25 blinks per 60 frames/
second, equating to about 12 hz, BUT if the same
system is powered by a variac, where things are said
to be isolated from ground, then the bulb does not
blink but displays a steady discharge.  Very Dry
ground conditions can make grounded neon discharges
much more difficult. But in this case we wonder if
this blinking bulb process somehow correlates to the
resonant frequency of the earth, and if this blinking
could be used to regulate another power source we
might be able to procur a novel method of producing
low frequency currents.
