Wardenclyffe - Tesla's true intention

[Farmhand]

Sputins, Tesla made Arcs (lots of them) and Eric does as well. That is one of the
things a Magnifying Transmitter can do and should be able to do, it makes
enormous potentials, and the terminal can be temporarily made to leak to "display the potential" ?

The coil I have can Make arcs or not depends if I want to or not. A gun can
be used for a club and a firearm. Things have multiple uses. Some want to
make very high potentials some don't.

I think Ernst just doesn't want Eric constantly shoved down his throat, neither do I.
People have the right to not appreciate that.

Here is my coil with and without an added "leak point" . Where is your transformer
how much potential can it provide ?

This clip shows both how big the arcs can be, and how much they can be suppressed.

Power level leak test - YouTube

Eric has opinions on others and others have an opinion on Eric. Eric does not
own Tesla tech or the Magnifying Transmitter name.

Tesla states that for telluric transmissions a high potential and relatively low
frequency is needed, and leaks should be minimized, the elevated terminal
design and shape is important to minimize the leaks.

I am interested to see the potential other peoples transformers are making.
Only way to really see it is by arc display. I'm sorry you Eric followers feel the
need to foist Eric's work on everyone else.

Having said that I do not totally ignore Eric's work, I get some things from Eric
and some from other places.

I don't believe anything but a 1/4 wave structure covering the secondary and
extra coils both is needed. The concatenated mode of operation is in my
opinion very unlikely or impossible. Tesla also states that a high rate of
transformation alone is sufficient to effect telluric transmissions, which in my
view seems to say no special mode of operation is required.

To be totally honest I think almost everyone is making more of it than it is.

Bottom line is, if a transformer can make arcs why not show them ? In my opinion a
transformer that is capable of continuous discharges into the air shows it has
the ability to produce a "loaded" high potential.

Tesla loved to make arcs, and gave tips for producing better arcs and sparks.
He considered it a valid way to show and determine the terminal's potential.
True or lie ?

Cheers

[Ernst]

Thanks Farmhand!
That is one post that I 100% agree with.

I do not want to discuss whether or not Eric is accurately replicating (i.e. copying) Tesla's work, for the same reason as I would not start a discussion on whether or not grass is green; it is completely obvious that he is not. Read his work and read Tesla's and you WILL find the differences. That is all I have to say on this issue.

Found another amazing statement on him:

- the only successful demonstration of Tesla's Longitudinal Dielectricity ever made available to the public

Tesla's Longitudinal Electricity 60 minutes

Is that the ONLY one???? Really????
In that case I will prepare the second demo and post it within the next few days.

Listen, it is not that I want to discredit Eric, but we have to remain realistic.
Eric Dollard in not Nikola Tesla. Eric does not have any patent or rights on Tesla's work, nor is he the only man who can replicate Tesla's work.
Eric Dollard is Eric Dollard, and really that is good enough. There is no need to make him into something or someone that he is not.

here on Longitudinal Electricity.
This relates to both the source of the "Free Energy" of Wardenclyffe and the way it can be tapped.

I will let Eric have the "only video on LE".

One comment though, with respect to your note "there are no special requirements". There are some relations that have to be observed when building even a basic TC in order to be able to get a good vibrating system. On the magnification of the extra coil ( part of a magnifying system ), Tesla clearly states in the beggining of his notes in Colorado,p. 52 of CSN ( attached ), a very important relation. Quote:
"The additional coil is" ( the extra coil ) ", as observed in the New York apparatus, an excellent means of obtaining excessive electromotive force. But it is peculiar that to property develop the independent vibration of a coil its momentum should be very great with respect to the impressed vibration. When such a relation exists the free vibration asserts itself easily and prominently. But when the impressed vibration is very large and the coil's own momentum small, the free vibration can not assert itself readily." The italicization is mine. Tesla goes on and compares the relations in process with that of a swinging mechanical pendulum.

Hope that this note helps some of you.

[Ernst]

@epwpixieq-1 (where did you get that name???),

Please note that the document is on Longitudinal Electricity. If I remove the extra coil and probably also the secondary (still have to test this) the results described in that document should not change. It is only the impulse current in the primary which creates the documented effects.

Back to Wardenclyffe connecting the final dots....

In my experiments I do not get more than about 25% out of my magnifier coil (coil #4), so returning to my literature study I have found the following:
Letter to J.P. Morgan dated 5 Nov. 1903:

Dear Mr. Morgan:-
The enclosed bears out my statement made to you over a year and a half ago. The old plant has never worked beyond a few hundred miles. Apart of imperfections of the apparatus design there were four defects, each of which was fatal to success. It does not seem probable that the new plant will do much better, for these faults were of a widely different nature and difficult to discover.
As to the remedies, I have protected myself in applications filed 1900-1902, still in the office.
Yours faithfully,
N. Tesla

As I have not found a copy/scan of the original letter I am not sure if this is a real letter by Tesla but it could explain why my set up failed. So which applications were filed in the mentioned time frame?
685.012 1900-03-21 Means for increasing the intensity of electrical oscillations
787.412 1900-05-16 Art of transmitting energy through the natural mediums
655.838 1900-06-15 Method of insulating electric conductors
723.188 1900-07-16 Method of signaling
725.605 1900-07-16 System of signaling
685.957 1901-03-21 Apparatus for the utilization of radiant energy
685.958 1901-03-21 Method of utilizing of radiant energy
1.119.732 1902-01-18 Apparatus for transmitting electrical energy
The first concerns cooling coils to reduce the resistance.
The second using standing waves in the natural medium (earth).
The third insulating conductors with a frozen material.
The fourth and fifth using different frequencies for sending messages.
These could very well be related to the 4 problems that Tesla found.
Then in 1901 he files 2 patents concerning radiant energy. It looks like he has removed this from the Wardenclyffe design. The fourth coil served 2 purposes:
- the feed back circuit of the primary circuit
- converting and redirecting the incoming energy as described in the 1900 article
By removing the energy generation part of this system, the other function (preventing discharges from the top of the extra coil) can be done in a much more straightforward manner; by increasing the size of its top-load.
This finally leads to the patent filed in 1902 which reduces Wardenclyffe to a system for telluric transmission of energy and information.

I think this seems the most logical and complete solution to the question of this thread.
Perhaps this also brings peace back in the camp

@epwpixieq-1 (where did you get that name???),
Ernst.

actually, it is a fundamental mathematical identity, first derived by Euler, abbreviated with letters in a nonstandard form.

[Ernst]

@epwpixieq-1,

Concerning my earlier statement:

If I remove the extra coil and probably also the secondary (still have to test this) the results described in that document should not change. It is only the impulse current in the primary which creates the documented effects.

I have removed these coils and tested it.
- with a complete system: I get 30 KV without amplification by an external coil
- with extra removed: I get 17 KV without amplification by an external coil
- with only a primary: I get 2 KV without amplification by an external coil

It appears that the presence of a strong electric field increases the effects significantly.
(which I actually should have known, as the original Wardenclyffe design was based on this)

It seems some physics forums and electrical engineers are quick to jump on the explanation of Wardenclyffe, as simply a radio broadcast tower. They do thusly despite the evidence Wardenclyffe was obviously more complex than a simple broadcast antenna for Hertz waves.

Most times when this concept is mentioned, they find it important to point out how poor a design Wardenclyffe was compared to the current advanced transmitters, and how Tesla did not know as much about radio transmission as them,despite the fact he basically invented it. IE Tesla was eccentric, crazy, was wrong and is not worth researching and couldn't actually do what he said he could do.

The most obvious point against Wardenclyffe as a radio transmitter tower is this:

Tesla called Wardenclyffe his World Wireless System and makes repeated reference to the ability of this system to transmit information or power around the entire globe, with only the single tower at Wardenclyffe.

Clearly, these so called expert radio and electrical engineers are forgetting, a normal Hertz broadcast system cannot transmit around the globe, hence our development of repeater stations, relays and communication satellites. Hertz waves are primarily line of site, with some special cases where we get some reflection off the ionosphere and so on. It is quite clear, Tesla was doing something very different, if he could transmit globally, as he so vehemently claimed.

I know very well, I need only drive 200 or 300 km and I will, in most cases, lose reception of all the preset stations on my car radio. Using Tesla's Wardenclyffe system, this would not happen. Anyone who sticks to this concept of Wardenclyffe, as just a radio transmitter, really needs to actually research and read Tesla's work, before they voice their so called 'educated' opinions.

In fact, we could erect a huge grounded metal screen or shield around the entire Wardenclyffe tower/system, and it would still have operated quite well and signals would still be receivable outside the shield. If someone thinks this is impossible, it is only because they do not actually understand what Tesla was doing at Wardenclyffe. Heaven forbid something does not fit inside their box.

Thought this point should be mentioned for posterity and to vent my frustration at some of these 'experts' not anyone specifically on this forum.

It depends on YOUR perception of "radio". To do it correctly you simply transmit the signal through the earth rather than the air. Disinfo averted.

Wireless is not necessarily "radio", but radio is wireless, wrap your head
around that. Wardenclyffe was not necessarily radio but it was wireless and
did have a radio aspect to it. A ULF wireless transmitter is not necessarily a
"radio" transmitter. When you tap a long steel pipe and someone can hear the
tapping a long distance along the pipe is that radio or wireless ? It's not
conductorless, And nor would Wardenclyffe have been conductorless.

To send signals and significant industrial levels of power to the other side of
the planet a tuned (resonant) receiver would be required. If travelling by car
you would most likely be listening to radio because of the lack of ground
connection even if a Tesla system was in place for global communications.

There is absolutely no reason why Tesla would not have been considering
using radio transmitters for local radio coverage especially for pocket receivers.

For household power in remote locations (small amounts of energy), just a
small grounded receiver would be needed. But for industrial power,
(and residential power in cities) the Tesla power transmitter would work to
transmit power from the Hydro plant or similar to the city area where the
receiver would supply the regular grid system in the city. Same with the
wireless signals, the wireless signal from the other side of the planet could be
received by a ground connected resonant receiver, then for the local area a
radio receiver could be used, and radio transmitters could also be used for
transmitting signals for portable radio's, close to a receiver the portable radio
would likely work well.

My bet is that if you erected a huge screen around the Wardenclyffe tower
it would effect the tuning of the tower because of capacitance and suppress
the radio part of the towers output, which Tesla admits cannot be totally
suppressed but it is useful. It might also allow the easier formation of leaders
from the grounded shield and cause discharges to it from the terminal of the
tower. Anything that de-tunes the transmitter by any means, be it capacitive
or other would adversely affect the transmitter.

My question to you is blunt. If you know so much where is your experimental
setup and where are the experiments. Show us you can utilize the four tuned
circuits (the concatenated tuned circuits) ( not the concatenated mode as
described by Eric), the four tuned circuits even using a connecting wire rather
than the Earth, the connecting wire can be Earthed.

Show us you can suppress the radio to less than 50% and get more than 50%
of the output in ground current or even close. I think that would be difficult if
using over 100 kHz but maybe not impossible.

Show us you can at least do something like this.

I am speaking of the common explanation of radio, nothing to do with MY personal perception whatsoever.
https://en.wikipedia.org/wiki/Radio
Can you point out where "radio" is explained here as being transmitted through the earth?

Enough with the weak "disinfo" comments already, I have provided numerous links, pictures, references and real information anyone can verify for themselves. If you call what I am saying is "disinfo", then your basically saying all these sources and references are disinfo, which is really pathetic. Many have been quotes from Tesla himself. It takes zero intelligence to keep calling out "Disinfo", whenever you cannot follow or disagree with someone.

Any reader of these topics will see this, so your just making yourself look bad when you keep pulling out the "disinfo" card.

@dR-Green & Farmhand

If you look back on my posts here, you will see I mention numerous times and fully agree Wardenclyffe uses a form of ground transmission. Thus Wardenclyffe does not fit the mainstream definition of radio as a Space wave transmission. So I am not sure why you two are trying debate with me Wardenclyffe used the Earth, because I obviously agree Wardenclyffe used the Earth as the main means of transmission. I agree there will always be some electromagnetic radiation ( ie radio waves ) from such a system, but the fact remains this is considered a loss in the case of Wardenclyffe, not the goal.

From this diagram( I previously linked ), it is extremely clear Wardenclyffe is concerned with the Earth, not the Air or Space.
http://www.ovaltech.ca/images/Scalar...ansmission.png
I fail to understand why I must repeat this to you, when my position on this was previously made very clear.

The screen I mentioned is a hypothetical device to point out electromagnetic radiation was not the goal of the Wardenclyffe tower, and such a screen would not be practical for many reasons, such as the ones you mention as well as size and cost. The point was simply, Wardenclyffe was not designed as an electromagnetic radiator. Tesla went through great efforts to minimize such electromagnetic radiation from Wardenclyffe.

This is again very apparent when you consider, no modern radio transmission antenna, has a gigantic spherical capacitance on its top! Again, clearly Wardenclyffe was not a simple radio antenna as we consider in radio transmission. If we put such a large capacitance onto a standard radio antenna, it actually greatly decreases our effective transmission power, which is why you do not see this done on ANY radio tower today.

Let me be blunt why I do not have experiments and demonstrations at present Mr. Farmhand. Not everyone has funds, nor space, nor time to spend on such endeavors, do they? I prefer buying food and a place to live at present, over spending my hard earned money on wire, scopes, electronics and so on. I assure you, if you wish to send me the money to pay my bills so I have time to do this, rent the space and supply me with the materials required, I could easily blow your little set-up out of the water.

Not that I could even grasp what is so special about what you have done from your video, the mumbling audio, lack of diagrams and explanation, and panning the camera around at your set-up, does nothing to further educate anyone about such things. It shows you can build a Tesla coil, as currently described in a hundred different sources, and use some standard electrical/electronics test equipment, and transmit some power through a long wire( extension cord ).

The waveform on your scope, clearly shows a perfect sine wave, which I know is not what you would get from an actual Tesla coil in operation. You simply built an RF Wired transmitter/receiver which looks like a Tesla Coil. We call it cable TV. I am not impressed in the least, because you show nothing unique, creative or special here, its all still right out of the electrical engineering textbooks. A science fair project, without the science fair.

It seems any time this forum makes a step forward, in a creative direction, some ego's quickly step in to push it back inside the box again.

[boguslaw]

I'm sorry but I have no time to discuss anything.
All I can say is that Tesla transformer is a hammer.
Extra coil is the momentum part of hammer. Sometimes Tesla called that all magnifying transmitter but some times he thought about the whole concept.
Surely the missing part is tuning fork which is a (missing) receiver part. Thus magnifying transmitter is really transceiver.
Earth is resonant cavity.

Now you know why Tesla transformer as shown in youtube videos is useless - it's like using hammer to break window because you are missing important parts.
It's hard to understand why people still do not grasp Tesla concept - it's easy.

It IS disinfo if you are saying it has nothing to do with radio. Put it this way, if a newcomer was to come along and read your (previous) comments, they would be diverted from the truth. They would be turned away from practical applications, and all they would have left is to make lightning bolts. Also the disinfo remark equally applies to your understanding and the disinfo of the people on the physics forums you are talking about, the ones who believe they know all there is to know about radio. Those people equally divert away from the truth. The disinfo is averted through not listening to them. There are also people going under the guise of being pro-Tesla, when in fact they are pretending to be that which they wish to destroy, and because they repeat exactly what the masses want to hear they automatically become the credible source. I have dealt only with facts and experimental evidence, all of which has been openly shared on this forum, and I'm called a shill by those who choose to disagree. Join the club.

Apart from that, earth wave propagation is known to the radio community/authorities, in order to experiment in this area you need a radio license, whether you are transmitting through the air or the earth.

Boguslaw, if I understand correctly, you are saying the TMT was both receiver of energy as well as transmitter of energy. TMT as receiver seems to be the point of Matt Blythe's video:
Tesla's Little Secret (Original) - YouTube
I don't think he's got the whole picture, but it's interesting.

This one seems to make more sense to me - see from 0:50 onward (short video):
Tesla Patent - Magnifying Transmitter - YouTube

He states in his comments that resonance is what matters here.
Here's my take:
This resonance would consist in pulses from the primary through secondary and resonant coil to the capacitor at the top. Once the resonant coil hits resonance, we then have a kind of pump, sustained by the resonant coil's ringing. The resonance of the structure (like a tuning fork) creates and sustains a useful imbalance between positively charged top of the tower, and ground - to allow the radiant energy to flood in.

In addition, this pulsing must also perpendicularly cross earth's lines of magnetic force. Perhaps the earth's magnetic field comes into play here as well.

In my limited experience with radiant energy, I have found that it flows opposite to conventional (hot) electricity: i.e., from ground to positive, rather than conventional positive to negative. If we consider the earth as Tesla's resonant cavity, then the TMT's resonance (and resulting open dipole/imbalance) would tap into the earth's radiant energy, which in turn flows up from the ground.

Comments by anyone welcome.

No skin off my nose, I never said there was anything special about the setup
just that it is a series of tuned circuits. You assumed I was implying it was special but it isn't and very inefficient as well. Your's is the ego.

I was asking for a simple demonstration from you with equipment that costs
very little to buy. I saved up to buy my parts and equipment. What's your
excuse ?

And a Tesla coil operated in continuous wave mode at resonance will show a
perfect sine wave. Is that a lie ?

This coil does not show a perfect sine wave. Because it is not operating in continuous wave mode.

Power level leak test - YouTube

Could you please define, "Tesla coil" , "Tesla Transformer" , "Tesla Magnifying Transmitter" , "Tesla Transmitter".

What are the differences ?

So far I see the use of the word magnification by Tesla as having nothing to
do with extra energy.

By the way I'm not trying to teach anyone anything, I'm stating my beliefs
based on my observations, and showing some of my experiments from some
time ago and from recently, you should check the dates video's were
uploaded and realize that people learn stuff as time passes.
