Dr Ronald Stiffler SEC technology

[iQuest]

Itsu:
   Truly appreciate your continued good efforts, learning a lot from your test setups, thanks for sharing the results of your work.  It is interesting to note that at 0:50 on Dr. Stiffler's Pretesting video, which has been removed,
the two L3 coils are not the same length.  The L3 coil connected to the Cree LEDs appears to have about 10 more turns, see attached screen capture. 
   Regarding the disappearance of 23MHz resonance from SA when you move connection from open end of the 2nd L3 series coil to open end of the 1st L3 coil.  If you haven't already checked, the result may be different if you
connect SA to other side of 100 ohm resistor to leave it in the circuit as top load for the 1st L3 coil.  This may be a factor related to equipment impedance as you noted. 
   Regarding some unexpected resonant points that you are seeing, electrical length and velocity factor may be at play.  Gyula posted this link http://www.teslaradio.com/pages/tesla_coils.htm to an excellent paper by the
Corum brothers.  I think these quotes from that paper are very interesting and may be applicable:

"Tesla clearly understood the velocity-inhibited nature of spiral and helical resonators and taught that, "The length of the wire coil in each transformer should be approximately one-quarter of the wave length of the electric
disturbance in the circuit, this estimate being based on the velocity of propagation of the disturbance through the coil itself." [U.S. Patent 645,576; Applied for Sept. 2, 1897]  It's not the physical length of the wire but rather
the velocity inhibited electrical length of the helical coil which must be quarter-wave resonant  (i.e., have forward and reflected wave-interference producing a standing quarter-wave resonance).  This was recognized by
Tesla, and this is the meaning of the phrase "...this estimate being based on the velocity of propagation of the disturbance through the coil itself."

"The resonant frequencies are called "overtones" instead of "harmonics".  Only overtones that are integer multiples of the fundamental are called harmonics.  For a nondispersive resonator the fundamental is called the first
harmonic, the first overtone is the second harmonic, the second overtone is the third harmonic, etc.  However, a helix is a frequency dispersive resonator - the velocity factor is NOT a linear function of frequency and,
therefore, the overtones of the resonator are NOT integer multiples of the fundamental."  (See attached Corum photo, resonant frequencies of test results are not integer multiples.)

"The voltage magnification in coupled tuned coils is nowhere near what is possible from a simple distributed resonator with standing waves."

"It can be shown that the ultimate limit in voltage rise on the coil is set by the degree of coherence of the up and back resonator waves."

Thanks for the advice on the other page Brad.
Patent 645,576 is interesting as it's come up twice now.
Also iQuest, your quote from 645,576 reminded me of Custer's ChannelWing aircraft, "It's not the airspeed, it's the speed of the air."
The coil former shown in the pic with the gent at the side looks like an outer receiving coil from Tesla's famous photo from Colorado Springs, where he is sitting making notes and streamers are flying everywhere. That coil was also pictured by the photographer who arrived in the final days of that trip and took a pic of it outside. That's where my tiddly Walgreen tower design came from, as a sidenote.

Speaking of 645,576, i've come up with a simple circuit version of that Patent. Tesla's used something like the brushes of a motor to inject the L1, but i've used methods similar to a Slayer Exciter and the thing works great !
It outputs wireless on the Ground connection when connected to an outside ground rod too, which is a bonus. Hasn't been properly tested as such yet (it's night now).

Itsu: Can your set up light up a neon bulb?  What voltage are you using at the input. What do you get at the output?
Sorry, but one more question. How many turns are your L3 coils, tuned to 13.MHz.

Nick,

my oscillator setup cannot light up a neon bulb, and it runs on a 12V SLA.
I have charged up a capacitor to 100v or so, that will be the output, but it strongly depends on the load.
My L3 coils are 70 turns on a 16mm diameter former using 0.6mm (awg 23/22) magnet wire.
The coil length (wire) is about 4.5cm. and coated wih 4 layers of varnish.

I do see severall dimensions of this L3 coil (see comment below too), but it all depends on the former diameter
used, the AWG (23 - 26) and the number of turns needed.
The goal probably is to get to the mentioned 26.62uH ±15%, see page 30 here:

iQuest,

thanks for the comments, 
yes the L3 coils seems different, see my comment to Nick above about that.
i tried many variations in measuring the both and single L3 coils using my SA, and the outcome is mostly the same.
Thanks for the link, i had seen it before, but will go over it again.

Slider, 

nice experiment, worth looking into.
I build myself a SEC 18-x and seems to work. 
I will do some tests with it as that was what Dr. Stiffler was using on his latest (removed) video.

Itsu--- I think this is where Doc was going but with this new 'Loop' and Cree Board.  Why he thought he could transmit through the earth instead of the other way around is the mystery.
--Lidmotor

Well, Tesla's patents are not for the faint of heart...

TK,

My interpretation of a negative COP is infinite COP and a negative COP is the result of a measured negative input energy. 

I'm not so sure I agree that negative COP = infinite COP. That seems to go in the wrong direction somehow. Since it happens because _input_ power is negative, doesn't that mean that the device is supplying power to the PSU instead of the other way around?

The consequence of such a device would be runaway into destruction unless limited.

I think I do agree on that, with some provisos.
Is it the device itself that will run away to destruction, or will it destroy its power supply?
Perhaps it just runs up until inevitable losses meet gains and operation stabilizes without blowing up.

The real question is, are the measurements accurate?

Regards,
Pm

Agreed. There may be other reasons to reject the measurements than simply the measurements themselves. And even accurate measurements can be misinterpreted, or even be irrelevant, as we've learned before.  I think I'd like to know a lot more about how the scope does measurements and calculations on those measurements before I write home to Mom about the extra Joules in the box.
