Last Question first. I have done this and the sign changed but was
grossly reduced in magnitude at range over the original negative charge.
I was limited here by the fact that the supply was originally ground
referenced. I feel my attempts to reverse the system were not balanced,
and therefore not valid in the strictest scientific sense. I am trying
to get good quantitative data, but am currently making an isolated supply
which I can count on. This is also a key point in the H2 thyratron
experiments where a critically controlled single ping can give highly
accurate and quatitative results. This will be developed as an inside
project this winter. I will know the answer!!!!!!
Now, the primary circuit doesn't enter into the picture at all except
perhaps as a polarity determining factor! Further, I think that only the
1/4 wave system (or some odd multiple) will perform as advertised.
The DC output from the spark excited TC (whether AC or DC excited via
spark/capacitive discharge) is a real fact of life and not a topic for
debate. Only the mechanism of production is open for disucssion! I am
saying that the very fact that we have a decaying wave allows the system
to be monopolar as a DC electrostatic source! Each alternation within
the resonator has less energy than the last.
The first hot blast from the primary system forces energy into the
resonator referenced to ground. This energy is of a monopolar form as
the first sign within the sinewave's first pulse occurs. Whatever ions,
electrons, chargeclusters, or whatever you might be happy with, are
emitted (usally from a point), they are accelerated away by coulombic
forces and these forces alone! At the end of the first alternation the
polarity of the output terminal slowly reverses and builds up to a
maximum energy and voltage level a good deal less than the last
alternation. (damped wave) Meanwhile the original charges have a kinetic
energy "Ke" and a velocity "v" and the bulk of the original charged
matter is at a distance "d" from the terminal. The new, weaker charge
will try to anull the prior output. Agreed? This will be accomplished
by attempting to sweep up and neutralize all the opposite signed
However, the coulombic force exerted on these rapidly fleaing particles
is tremendously reduced now due to their remoteness or distance (inversed
square law portion of coulombs law.) The naturally reduced energy of the
current pulse coupled with the reduced force at range on the fleaing
particles tend to not allow one (or the other) of the signed outputs to
sweep up the bulk of the prior emitted charges. The scenrio is now
repeated with each weaker cycle, until the damped oscillation in the
secondary dies out. Thus a single polarity electrostatic ion wave is
launched along with the stock electromagnetic RF component. I really
believe, with only qualitative data on hand, that one polarity (the
negative one) is the predominant mechanism active here. This much, I do
have data for, but must give the positive method an unbiased equal
opportunity with rigid controls in place.
It would stand to reason that one mechanism might tend to predominate
based on the physics of ion/particle/cluster production.
The DC supply which is absolutely unreferenced is a must have item. The
H2 thyratron will rule out long term ion cloud formation. The
electrometer and a claibrated receiving capacitance "of large surface
area" is a must.
Tesla's original distinction in difference between the equivalent
capacitance of micro thin wires (radio antenna) which attain there large
capacities via electric field line concentration and that of huge
elevated, large area, isotrpoic capacities which attain their capacity
via interaction with space itself, is no trivial extension. I feel this
is the salient point in the exercise. On is intrensically
electromagnetic and the other electrostatic. Naturally, I will keep all
posted. Richard Wall has recently posted on his findings as well.
Finally, all coilers worth there salt have experienced the hard shock
which occurs just outside the spark radius of of small systems when
holding a metallic object. As the sparks just lap at the tip of the
object, each hit yields a sharp shock. You were at a DC potential
(charged up isotropically via emitted ions) while not in contact with the
spark which found its ground path back through the coil. (you were
discharged) As you approch the terminal and the discharge is continuous,
all sensation of shock ceases as you are now part of the resonant circuit
via a plasma connection and the RF passes harmlessly over the skin. You
are no longer isolated as a capacity and can't accept a DC charge via the
Finally, try this with a small coil. take a piece of .0005" mylar strip
and place it next to a metal plate about 1" away and insulated from same.
if the plate is placed just out of spark range and itself insulated, the
mylar immediately slams into the plate on power up showing DC charging of
the plate. Or you could just use a simple electroscope attached to it.
Hope this helps in understanding where I am coming from on this matter.
