Peter, whatever happened with Eric P. Dollard?

Why pulsed DC?

So I've enjoyed learning from Eric and going through the references, including Tesla's Colorado Springs notes, Steinmetz and others. However, I've got a question. I understand the concept that electricity gets stored in the magnetic and dielectric field and then can oscillate between these two. Yet why is there something special about a pulsed DC source? Based on the references, I still don't understand why pulsed DC is special. Any thoughts from anyone?

Does pulsed DC do something special to the dielectric field?

From what I understand it is not so much pulsed DC....as in conventional square wave pulsed DC in modern circuitry rather it is DC Impulses.

Watch the video with Eric Dollard & Chris Carson. In it Eric explains the difference between AC, DC, Impulse and Oscillating.

Impulse waveforms in Tesla Coil Resonance have infinite amplitudes and the harmonic components are IN PHASE. Contrary to standard up and down DC waveforms where amplitude is limited and harmonics are out of phase. This is what makes Impulses special. The video has pictures as well to help explain.

wait a sec

how can harmonics be in phase?

Parts of them can be in phase.

They can be best lined up (mathematically) for best transfer by phase adjusting but I have never seen harmonics et al in phase or any math that would lend credence to it even being possible.

yes the idea is impulse having more punch through power, and as far as I am concerned it is similar to a typical ballistics problem.

For a very general example to make a point not be in any respect mathematically correct, if you have 100 grains of lead moving 1 million feet per second impacting an object or you have a 1 ton chunk of lead impacting at 100 feet per second the disturbance will be the same.

Both the lead and the watt are doing work by a force and it all comes down to power which is a function of both pulse height and pulse width, ie velocity and mass in the case of the lead and maybe also in the case of power. If the impulse were infinite sparks would be jumping all over the place and it would be uncontainable, so suffice to say they are not infinite in the real world.

There is no such thing as infinite or even approaching infinite in the real world applications as the peak of the impulse will be determined by the internal resistance plus any reactive components of the media.

At this point I have not seen any other things going on here that would lead me to a well grounded understanding of the 1.57c or magnification meaning anything beyond a transformer action.

I do want to believe but I am still not in a position to do so, and I do not know if its me or the manner in which the theory and information is put out here, and several of my questions went and continue to go unanswered to my satisfaction.

call me unenlightened Mr stick in the mud if that is what I am but that is where it stands with me LOL

Impulses NOT Pulses

Gestalt,

You gave an excellent response to Skaght's question, although I would have to somewhat agree with Kokomoj0 on the phasing issue of harmonics. I may, at some latter time, give my thoughts on that interesting problem. But for right now here's some basic considerations of an Impulse. When generally considered, you have two possibilities with super-imposed waves, constructive (additive) or destructive (subtractive) "interference". For an Impulse, the wave-front's steepness is determined by the parasitic capacity and inductance of the discharge path, the tail however is determined by the resistance or conductance of the discharge path and the storage capacity of the discharging medium. This matters because the rise time of the Impulse can be considered to be based upon the "bandwidth" of the wave-front (similar to a "Pulse", which is limited due to parasitic inductance & capacity) this would determine how many "waves" are composing the wave-front of the Impulse. If you consider radiation resistance, then you will have a certain amount of Hertzian waves emitted near (and progressively less further away from) the source of the disturbance (i.e. the discharging storage medium). As for a nearby circuit it will be affected by two entities, the radiated hertz waves and rapidly changing Dielectric and Magnetic gradients G & H this causing mutual coupling to the surrounding circuits. Here, with mutual and radiative coupling, the harmonics play a bigger role in my opinion, this followed with the understanding of FREE OSCILLATIONS (NOT "ALTERNATIONS") will give much more insight into the Tesla transformers workings.

Interestingly (for fun) you can HEAR the difference in bandwidth between a Sine, Impulse and Pulse with a pair of head phones (I actually did this experiment the other day while building a tube amp). The square wave will have more HIGHS and a consistent sound level. The Impulse will have Highs initially but then fade and sound level varies giving a super imposed "beat" to the sound. A sine wave is a "pure" tone (if you have a good signal generator) and its sound level doesn't "seem" to vary. The best tests are done at 30 to 100 hertz where you can easily tell if there shouldn't be any high frequency sound or secondary beats.By the way, I would like to give a HUGE shout of thanks to Jpolakow and Information_synthesis for "modernizing" and uploading the Generalized Electric Wave and other books of Mr. Dollard (to the yahoo N6KPH group). (They almost look like modern text books!)

construction details

How important is it that the secondary turns remain parallel?? i.e. can you use a "basket weave" style.

I tried to wind the secondary using 14ga but it is very unfriendly.. small changes caused by the dowles bending slightly caused bending and twisting of the wire. Which lead to not very parallel turns and a horrible experience with winding on a large wood former. I threw in some toothpicks to keep the spacing sufficient.

Anyways it makes a good directional radio? Picks up 1620 with no problem and no 60Hz hum.

Making the extra coil today should be easier with the thiner wire.

And on the primary. How close should the two turns be? Would as close as possible be the place to start?

Furthermore "DC" is not what people think it is, DC has NO FREQUENCY thus is TIME INVARIANT so ANYTHING that does something other than look like a horizontal "straight line" is not "DC". The term CONTINUOUS CURRENT is more accurate a term than DIRECT CURRENT. If the current varies in time it is no longer DC, but now AC, OC or IC superimposed upon DC (or CC). Hence why you use AC filters on DC circuits to IMPROVE the DC "characteristics" or "cleanup the DC signal".

The understanding of PULSES comes from that of SINE WAVES and NOT ASYMPTOTES. In a general sense, Pulses can be described by odd-order harmonic sines superimposed upon a fundamental sine. DC Pulses are "DC Offset" AC square waves. The "rise time" and "fall time" of a square wave relates to its "bandwidth" or how many (odd-order) harmonics are superimposed upon the fundamental signal. Capacitance and Inductance act as filters, which slopes the edges of a perfect square wave, thus there will never be an infinite rise time square wave, if any amount of inductance or capacitance is present. Generally in digital circuits too fast a rise time can cause issues so the slope of the wave is carefully chosen to "play" well with the logic elements used.

Impulses are an interesting subject but for the sake brevity and not belaboring the issue, I put up some excellent references to the subject and links to them via my Scribd account.

By the way I would like to give a HUGE thanks to Jpolakow and Information_synthesis for "modernizing" and uploading the Generalized Electric Wave and other books of Mr. Dollard. (They look like modern text books!)

Hi Garrett, So am I to assume that Batteries don't supply DC then ? Because
the voltage of a battery varies all the time when in use ? If batteries don't
supply DC then what do they supply ?

My understanding is that DC just doesn't alternate from positive to negative
or negative to positive. For DC to be only a non varying voltage is a very stiff
requirement.

Cheers

So then from the above reasoning, impulses work better. Unless I'm mistaken, that doesn't explain why you couldn't use AC impulses, rather than DC impulses. A lot of the free energy dogma seems to indicate that if you switch to AC, the magic goes away. From the above explanations, I don't see why an AC impulse signal would present a problem. i want to understand the underlying physics, so I'm hoping to continue the discussion on the topic...

Who's free energy dogma? If you are referring to Peter Lindemann's explanation from the "Free Energy Secrets of Cold Electricity" then you had better think again. I am by no means saying that Peter is not giving out accurate information as far as he knows. All I am saying is that when asked in July at the Renaissance Charge Conference what he knew about the importance of parameter variation with regard to "free energy", he told me that that sounded like "hocus pocus" and that "Eric didn't stay around long enough to explain himself". (Referring to first EPD forum posts in 2010) I am not really sure why Peter acquired the Chris Carson Electrostatic Machine without knowledge of parameter variation but that will be a story for Peter to tell...


If you look at the math of energy storage by means of Dielectric or Magnetic, you will see something significant happen when you start to vary the parameters. For example, the magnetic:





Start playing with L and i and see what happens to the energy. These equations show that you get a rise in energy when lowering the inductance. I am currently using a dual AC waveforms to experiment with this at home. You can see my preliminary results using a generic core material here: http://www.energeticforum.com/renewa...tml#post183463 As far as I am concerned, this waveform is worth a second look (When I talked to Eric, he said it looked like I was getting somewhere).

From an archetypal view at all of this energy mess, I see variation in the parameters appearing all over the place. Just look at the Veljko Milkovic Two Stage Mechanical Oscillator. What is it doing? Why does it show more energy out than in when tuned correctly? I don't buy it as being attributed to gravity only. Gravity only assists in the oscillations of the pendulum which from its imbalance changes the parameters of the oscillations much like the oscillations of parameter variation from the dielectric and magnetic resonance components in the control winding of a MAGAMP. EPD quote: "Just keep them swinging"...

I think that pulsed DC is more for the Bedini machines and the IMPULSES RETURNED by the discharging inductor from which the passing magnets saturate the cores causing an INDUCTANCE CHANGE in the system.

anytime you have delta t, you do not have DC.

DC is the near steady state difference in potential.

The idea that a varying voltage is dc is nonsense though a full wave rectifier for instance is considered pulsed dc, then when filtered and loaded the variation is considered ripple, or the ac component riding on dc.

[Farmhand]

I think the terms are mostly outdated and need changing.

AC or Alternating Current should instead be Alternating Potential.

DC or Direct Current should instead be Continuous Potential.

Alternating Current should be reserved for current that changes direction or polarity.

Direct current should be reserved for current that does not change direction or polarity.

DC as an unchanging potential should be just considered a "scalar potential" shouldn't it ?

Impulses in my mind would have an almost instantaneous rise in potential.

Pulses can have a more gradual increase in potential.

That's my uneducated and unenlightened misunderstanding of it anyway.

Archtype Electric "Waves"

General or Archtype Electric "Waves"



The Cyclic or Periodic variety:

1) Forced Alternations: (example, generator or alternator)
Alternating Current, Undamped - Continuous Level
Time: Radians per Second
Effective Field Energies: ONE, Magnetic OR Dielectric

1A) Constant Potential (this is what you use in your home)
RMS Current changes with load impedance, RMS Voltage remains constant

1B) Constant Current
RMS Voltage changes with load impedance, RMS Current remains constant

2) Forced Oscillations: (example, LC tank or coax)
Oscillating Current, Undamped - Continuous Level
Time: Radians per Second
Effective Field Energies: BOTH, Dielectric AND Magnetic

3) Free Oscillations: (example, LC tank or coax)
Oscillating Current, Damped - Logarithmic Rising or Falling Level
Time: Neper-Radians per Second
Effective Field Energies: BOTH, Dielectric AND Magnetic

NOTE for 2) & 3) in a distributed element network like a coaxial cable a harmonic wave (square wave) can develop rather than a fundamental sine, which a lumped LC tank would produce.

The Acyclic or Aperiodic Variety:

Impulses:

A)Magnetic Discharge (through an "effective resistance"), Damped - Logarithmic Rising or Falling Level with a Steep wave-front
Time: Nepers per Second
Effective Field Energies: ONE, Magnetic

B)Dielectric Discharge (through an "effective conductance"), Damped - Logarithmic Rising or Falling Level with a Steep wave-front
Time: Nepers per Second
Effective Field Energies: ONE, Dielectric

The Non-Cyclic or Non-Periodic Variety:

Continuous or Direct Current (NOT PULSED)
Time: NONE
Effective Field Energies: BOTH, Dielectric AND Magnetic

A)Constant Potential (a battery)
Current changes with load resistance, Voltage remains constant

B)Constant Current
Voltage changes with load resistance, Current remains constant

NOTE, All of the above can be simplified further (condensed to only 4 general types) but I thought it best to expand the General Archtypes a little bit to give more insight.

EVERYTHING ELSE:

Every other "wave" type is a combination of the above periodic, aperiodic and non-periodic types and can be looked at as compound waves.

Compound waves with DC Source (example):

Battery to BoomBox (radio) initial turn on is a Dielectric impulse, charging the filter capacitors. If on but not playing any music a quiescent current draw is DC. If playing music Load impedance changes dynamically, this causes a changing level in current draw and subsequently an AC signal is super-imposed upon the DC power signal from the battery. During turn off, if there was a high current draw as the switch was flipped off, then a Magnetic Impulse would be seen, although it would be very small due to low inductance.

Tesla Longitudinal Wave Energy [Video Transcript] Excerpt:

[mikrovolt]

When compression and rarefaction is sufficient to observe
it becomes more evident that transverse is not the same.

The boombox is acoustic example. Two people at ends of a rope
can demonstrate both transverse and longitudinal waves.

We sometimes use a function in an equation to produce a meaningful
graph is not always evident so we plug in numbers and forget the demonstration and it becomes dogma.

The lump transmission line or a tsunami are other examples to help see there is more than transverse waves. Some are more noble and would like to harness some of it as free individuals.

Theoryexternal to the physical body exhibiting the effects of gravityif I can.

This takes us to the Landers Installation of George Van Tassle. Contained in his Landers Installation was a hemispherical structure approximately 50 feet in diameter and thirty feet high. This structure served as a magneto-dielectric transformer, operating at a potential of 100 kilovolts. This is the same potential as used by Marconi and Alexanderson. In a strange way it seemed like the Wardenclyffe Dome had come back and was waiting. George Van Tassle called it the INTEGRATRON. This structure was founded upon archetypal Four Quadrant

[Kokomoj0]

Here is what bothers me. Meyl regardless of how well he duplicated teslas work put his coils on a printed circuit board to test the theory. The kool thing about that is consistency. The windings are cad drawn and perfect spacing etc and that is good for splitting hairs. He had about a 4 turn primary and roughly a 90 turn secondary on the other side. The 4 turn primary was underneath the secondary and I would estimate the secondary was about 62% spacing incidentally.

Now what bothers me is that he said in his lectures that he was able to get at 3 different schools where he taught how the device works, he said they (the students) measured 100%, 300% and 1000% output over input at the receivers.

So did he get lucky and get something right by accident or doing some kind of magicians trick or what?

Well needless to say all the german physicists are all over him about this faster than speed of light business and calling him a fraud etc etc.

Now interestingly another physicist somehow measured the density around the dome while meyls towers were in operation and he charted out it all out and was surprised to see that the density was substantially greater on the side facing the receiver.

So is meyl just leading us up the golden path or did he get really lucky and just happen to build a device that works?

There is an old saying that goes, you cant argue with success, at least not much. and "IF" meyl really had success did he use erics math or how did he derive his work?

[kitcar]

For german speaking readers (or use google translate), here Meyl is debunked.

There is a guy "Jensen" selling replications of the the meyl resonating coil sets on ebay.com for a thrith of the price by the way.
