Wardenclyffe - Tesla's true intention

[dR-Green]

I suspect the frequency of the received energy to be low, in the order of Earth resonance (12.78 Hz) - Schumann resonance (7.5 Hz?) = 5.3 Hz.

How did you come up with that number (12.78)?

Based on earth's diameter it is approx 7.5 CPS assuming the velocity of light. Pi/2*this velocity = approx 11.7 CPS, which I believe is the average velocity claimed by Tesla.

Based on earth's circumference its frequency is approx 23 CPS. That's also the number that was given in a non-electrical geology course. Tesla says approx 12 cycles per second - the question is, based on what conditions. Deriving frequency from Pi/2*c comes closest but doesn't match your conclusion.

Forgive me Dr Green, I did not grasp the full meaning of your previous post, where you had coils which were fixed in position relative to each other, and only the ground connection was moved. Indeed, I would expect this to not follow the inverse square law and would depend greatly upon the quality of the ground connection and soil or ground conditions.

Might I suggest that the characteristics of the Earth at the ground connection would have a great deal of effect upon results of such an experiment. For example, if performed outside, after a significant rain, I would expect your resulting graph would change greatly. As noted in this forum already, Tesla's final choice for Wardenclyffe had a very significant structure beneath the ground, which was eventually meant to be flooded with water. Perhaps even the local water table, may even have been connected to the ocean to some degree. Salt water and wet Earth being very good conductors of electricity. The point being, the conductivity of the ground in such circumstances is most definitely relevant.

I would also consider, that small scale experiments just may not be capable of producing the same effects as Wardenclyffe was capable of. In the same sense as the waves of a small stone thrown into the ocean, would be exceedingly difficult to detect amongst the greater wind waves. There is likely a critical threshold of power, to electrically move the Earth as Tesla intended for industrial power transmission. That is not saying, there is no merit nor discoveries to be made with small scale apparatus, such as others have demonstrated.

I would point out the mention of this energy traveling quite well through rock, is an important clue. Radiation cannot travel through rock or Earth very well, but energy similar in nature to sound, would travel through such mediums very well. That is a mechanical or impact like electrical force, rather than simple AC oscillation. Furthermore, this is akin to the velocity of sound, increasing with density of the medium through which it travels. Such a mechanism provides an explanation for the Hairpin circuit as well.

The "Hairpin" circuit, in which energy is made to travel through a path and light a lamp, in which said path is electrically a short and should pass no electrical energy.

"Additionally, Tesla discovered an amazing phenomenon which removed all doubt concerning the true nature of energetic carriers at work in his apparatus. Tesla arranged a very heavy a U-shaped copper bus-bar, connecting both legs directly to his disrupter primary. Across the legs of this U-shaped bus-bar were placed several incandescent lamps. The arrangement was a very evident short circuit The lamps were illuminated to a brilliant cold white light, while being shorted by a heavy copper shunt Uncharacteristic of particulate current electricity, the bright but cold lamps revealed that another energetic current was indeed flowing through the "short-circuits""

If we think of ithe "hairpin" circuit in terms of a mechanical impulses( the other energetic current ) and not electrical forces seeking the shortest path, it is far easier to grasp its mode of function.

There's a similar interesting thing mentioned I think in the "On his work with high frequency AC" book. It's simply a copper rod/wire connected to one terminal of the coil, with the two terminals of an incandescent lamp connected at different points along the rod. By placing the connections according to the standing waves the bulb can be made to light.

The earthing here is going to be upgraded but it's not cheap, I've just done some basic testing so far to see if it would work at all and start to get an idea of the whole thing. It can be observed in real time that the power received varies by pushing the (receiving) earth terminal in or out of the ground, the deeper the better. On the plus side I live in a very wet country, and there's a lot of springs in the area and boggy/marshy fields, so the conditions are about as good as I could hope for. And the sea is only a few miles away so no doubt a beach experiment will be done some day. I suppose the biggest problem regarding transmission experiments is that it's not possible to make a portable earthing arrangement for the receiver to be earthed as adequately as the transmitter. (Enter the Crystal Radio Initiative).

One of the most important factors in scaling the Colorado Springs coil is to match the original coil characteristics. For example impedance is matched to the full scale model, e = i*Z. So a certain input to the full scale coil will yield the same output in a scale model of any size. But the frequency varies, high frequencies apparently being not as efficient.

However, I think Ernst put something in one of his videos regarding beat frequencies or something like that, and achieving a low frequency modulated output compared to the higher resonant frequency of the coil, thus impressing the currents upon the earth at the 'necessarily' low frequencies, but Ernst is using spark gaps. It will be a very simple procedure to apply regular amplitude modulation at any desired frequency to produce the same effect, which is something I intend to investigate.

[TheoriaApophasis]

So so so sooooooooo many of you people are not (no offense) not using logic when you're approaching Tesla in his thinking.


Yes, Dollard is correct.


But 'everyone' is not using deductive comprehension in Tesla's mental pattern , synthesis, and his methodological approach.

You're reading HIS writings, great, but there is NOT 1 person in a MILLION researching Tesla who researches what TESLA was researching!


All Teslas (most) photos are staged, and the MOST STAGED photo of Tesla, he has his hand on "HIS BIBLE", THEORY OF NATURAL PHILOSOPHY by Roger Bosckovich.


If any of you claim to grasp Tesla WITHOUT having read "his bible", you're just spitting against the wind.


The principles of field convergence / divergence, vector modalities, Platonic retroductive analysis etc etc. That space IS NOTHING, is only an attribute of a field (my next paper) are all within "Tesla's bible".


You must must must read it to grasp Tesla.

Smart people "read the master(s) work"
The smarter people are reading "the reading material OF THE master".

[TheoriaApophasis]

How can Earth has iron core if iron become non-magnetic in high temperature.

You dont understand magnetism, extreme COLD kills off a magnetic field, not heat. Superconductors are supra-diamagnetic at extreme cold.


You're looking at it UPSIDE down from a dielectrically capacitant object, a "MAGNET", which loses its magnetic field when heated.


Your "magnet" you hold in your hand has attributional magnetism at a ratio of 3.23606 Dielectric to 1 Magnetism.

Heating that so-called "magnet" kills off its mag field, but only as attributional to killing off its dielectric capacitance in the heating.

Again, its seeing things backwards regarding magnetic induction (the TRUE 'magnet') vs. a dielectrically capacitant neodymium (for example) with attributional magnetism.


Induction of molten iron in a solenoid field is a given

https://www.youtube.com/watch?v=6B9EA7Ktc8w



Magnetism is definitionally radiation, is spatial and polarization (opposite to that of dielectricity).

A superhot ball of iron has enormous capacity for magnetic induction either from field induction or self-induction by its own swirling convections within the earth.

The scope what Tesla did is very diverse.

I think we are slowly reconstructing what was neglected and lost.

When making a point it is useful to explain an experiment to something specific Tesla was doing. The care in which we describe the details and charecteristics of electrical nature is how we can build greater understanding.

What is all this jabber about magnets ?

[dR-Green]

You're reading HIS writings, great, but there is NOT 1 person in a MILLION researching Tesla who researches what TESLA was researching!

A very good point. Unfortunately there is not even a million people researching Tesla who have more than a superficial interest because they want free energy, and nothing more.

People who are deeply/sincerely interested inevitably discover the philosophy of all philosophies, end up experiencing the philosophy to a point that seems like obsession, they are compelled from within to go further. "Researchers" merely become aware of it, nothing compels them to comprehend it.

So unfortunately most don't consider the unseen foundational philosophy to have any relevance to the visible work.

They should also start reading and comprehending Walter Russell.

Oh well yes, not literally ANYTHING close to a million. That was just a hyperbolic point.
TRUE philosophy , ie Pythagorean definition of same is NO different than Science, all are two sides of the same coin.
I translate ancient Greek and Prakrit.
If you could SEE what is IN the ancient Greek about the Aether, it would make your head UNSCREW off your shoulder and fall off.

Plotinus goes into the Aether in ways that would have stunned Tesla and Heaviside.

Even Aristotle KNEW (got it from Plato) the 4 archetypes of Aether,

Radial
Circular
Spatial
Counterspatial

Odd you mention that, Since I am the one that JUST digitized Russells 3 main works and made them searchable.

Also uploaded here:

I have been banned from that site at least 5 times for uploading SO many books. So I eased off on THAT site.

I have " most books" on servers in Russia, Romania, and here in the USA, (that and I have over 250 hard drives)
If you are looking for a book go to Library Genesis
There is NO site on earth like it, They have "most of" my stuff too.

Here is Roger Boscovich work , i.e. "Tesla's Bible" :
https://archive.org/details/theoryofnaturalp00boscrich

I have 12 Terabytes of PDF books by the way. I go by "God of PDF books" on some websites.
Most of that (obviously) I "acquired" BUT I also personally over 20 years scanned in BY HAND many many many 1000s of books.

(yes, 12 Terabytes of PDF books)
I have destroyed at least 20 (more) flatbed scanners over 20 years.

VERY VERY ODD you mention Russell, since TODAY, I plan on uploading his main work UNIVERSAL ONE
There IS a scan out there, but its VERY VERY BAD!!! and some pages cannot be read

My digitized versions of his works above are missing his diagrams, So i will, TODAY (or tomorrow) upload a professional scan of his book in.

[dR-Green]

Awesome stuff! I buy hard copies of the 'important' books but the pdf download always precedes it so thanks! I'm currently just over half way through reading Divine Iliad vol 2, A New Concept Of The Universe was probably going to be next. According to Russell he was told by Tesla that he should lock his work in a vault for a thousand years until humanity is ready for it. I'm becoming pretty convinced that the basic principles of "Creation" as described by Russell is what's demonstrated by Eric in his old CIG experiments...

That's a lot of books you have! Have you read them all?

Thanks for the Library Genesis link, tested it on something that took me ages to find manually, and it was listed. So that should come in very handy.

Any idea if this publication is any good? I hate it when they make useless reproductions and end up having to buy it twice.

You are MUCH better off reading UNIVERSAL ONE before reading "New Concept of the Universe" ............while Universal One was created earlier than New Concept, ...........Universal One is his magnum opus....and "New Concept" is more of a "this is what I kinda have left to say"

To be sure, his "New Concept" book is an orange already "half squeezed" as far as brilliant concept compared to Universal One is.


Libgen.org is located in RUSSIA, it sometimes goes down at NIGHT, because thats when Russia is active, but download during your daytime (Russia is asleep)


I will have a PROFESSIONAL FULL copy of the UNIVERSAL ONE done for upload by tonight. Complete cover to cover with excellent resolution on ALL DIAGRAMS.......


There is only ONE copy online of it (including the many many diagrams) and it REALLY REALLY STINKS!!..... and parts are UTTERLY unreadable.



Read all 12 Terabytes of books? Not even if I had a 1000 lifetimes.


Ive been busy enough doing translations and have written 12 books already.

1 Terabyte ALONE of my PDF book collection is already much larger than MOST descent sized libraries.

much less 12 Terabytes.




Oh yes, I know about Teslas comments to Russell. There are a few things Russell gets stunningly wrong, but that doesn't change the enormous amount he gets right. So, no big deal.


I will post the link to the NEW perfect copy of "UNIVERSAL ONE" here when I am done , which will be in just a few hours.

@TheoriaApophasis

Thank you very much for the scans and information as to what Tesla was reading in that photo! I sincerely appreciate your efforts to spread this knowledge. These concepts and works should be far more available to people.

Indeed we can look at Tesla's work as a scientist and engineer, but most importantly we must look at him as the visionary he was. A visionary trying to "Increase Human Energy" as a whole, trying to improve worldly conditions for all men, trying to seek the real Universal truths and most profound answers and give them to the world for the benefit of all.

Tesla's true intention of Wardenclyffe, was not just a power distribution system. The Wardenclyffe system would have transformed, improved and advanced the state of our entire planet. Advanced the world and mankind to a state few people can imagine nor dream of today. Wardenclyffe would have brought on an entirely different way of life and living, much more advanced and successful even then what we have today. The underlying science behind Wardenclyffe, would have and still can send us into a completely new age of abundance, equality, understanding, purpose, unification and exploration.

We are still in the dark ages, when compared against the vision of Tesla, Russell and so many others.

Make sure to tape your ears closed when you read Boskovich's work, ...reading that text will make your brain explode.... it does MOST people.

There is a HUGE SECRET (I lecture on this) regarding Tesla and people like Tesla, and people like his guru Roger Boskovich,...... or people like Maxwell, and Heaviside.

Its not in their brains (to some degree, their genius of course), its NOT to be found in their writings (as most people think it is),...
it has to do with something that was 100% LOST about 150 years ago.
Its a Platonic methodology of abductive/ retroductive synthesis, a thinking methodology known as retroduction.

Its far superior to deduction and induction.

If you were the rich brat son of some super rich family back in the 1500s, 1800s, 1600s, 1700s, etc. you were forced to understand the methods and works of Plato, Plotinus, Proclus.
I translate Plotinus, for example......consequent to this, every really really intelligent thinker / author that is in outer space mentally, was reading Proclus, Numenius, Syrianus, and especially Plotinus, or even just Plato


Allllll (and I mean 100 dam* percent) of those 8th thru 17th century "Christian Mystics' that wrote stuff so deep and complex and wonderful you'd think it just wasn't possible. Everyone of them was reading Plotinus. Every single one of them.

The same way architects today look at the Parthenon and say "H3LL, Even my Phd in engineering, I still couldn't build this thing if given a billion $$$ and threatened with death!!???!! "


Boskovich (Tesla's 'god') was an Ultra-ultra-hardcore student of the Platonic method.


You might ask "Ok, what was Roger Boskovich reading other than Plato and Plotinus where he got his logic and methods from?"

The PERIPHYSEON, .... insanely HARD to buy a copy of this giant collection.
Oh wait, thats right, I scanned that in years ago (along with many 1000s of other books), heres the link to THAT collection:
Eriugenas PERIPHYSEON Rare Collection 4 VOL English & Latin Original | Scribd





You can have the most intelligent electrical engineer on earth, that is SO smart he makes everyone else look like pond scum, but if his mental method is trash, hes not going to discover or invent anything!!!!!!!
You can read a bit about retroduction "Abduction" (problem solving / thinking methodology) here at page 85 of this book I uploaded:
Vol 1 Neoplatonism and Contemporary Thought

Or get a taste of this type of problem solving / thinking methodology here I just uploaded:
Syrianus 3-4:
Sryrianus 3-4

The question then is "what the he11 is the big deal"? Well its a lot. Its why Tesla got so far 'down the road'
He had the brains, the FUEL, but the high speed device was his methodological approach he inherited from Roger Boscovich and Plotinus (which Tesla did read)


Tesla said something like (paraphrasing here) ........"Poor Edison!!! All those years trying to perfect a light bulb, if he (only used my method of logic) he could have done it all in no time!!!"
Tesla , his guru Boskovich and others used a wholly lost art of retroductive thinking / approach.


useful but inferior:
Deduction:
I heard so and so say she dropped the needle over there, and bob said the needle was 4" long, so we know what to look for, wind speed indicates since it was dropped from 5 feet up, it should have fallen on THAT side of the haystack.

Induction:
Well, theres a needle in a haystack, it was last seen over there on that side, needles are heavy, so Im going to go looking over there for it

Superior in every way: (Tesla's method)
RETRODUCTION / ABDUCTION:
I know the properties of a needle, I know the properties of Hay...... watch this!
lights a match......POOOF......!! All is gone in a second in a giant flame

Theres the &@**$& needle!!!! Hay burns, metal needles dont.

Problem solved
..........(deduction and induction are still looking in the hay)


Deduction and induction are looking in a murky tub for a gold coin (wisdom, insight, invention, solution).
Retroduction says "scr3w all this nonsense" and pulls the plug and taa-daa, there's the coin.



This type of method is also called via negativa , or Apophasis. Its positing (the answer) thru RAPID negation/ elimination.

If you know the properties of ABCDEFGHIJ..........and X.........and if you are looking for X, then you literally "burn ABCDEFGHIJ into the dirt in a millisecond leaving your answer X" right in front of your feet.

Incredible book on same I uploaded:
The Unknown God. Negative Theology in the Platonic Tradition by Deirdre Carabine


All that "wonderful stuff" the writings, the architecture, the lost secrets of HOW to make things, how to discover things from "dumb people" back 5000+ years ago, (or even Tesla) has its epicenter in via negativa / apophatic / retroductive methodologies.

Tesla, IN THAT PICTURE, has his ONE hand on his head pointing at his brain, and his OTHER hand on his "bible", Boskovich's work..... meaning hes 'channeling' (in a manner) this methodology of thinking to solve the problems to all his issues of his countless inventions, and fantastic stuff.

We give 100% of the credit to Tesla's Brain-Power in his creations / inventions........ really its more like 40%, the 60% IS this/that methodology.



There are some really really intelligent folks with brain power (fuel) out there,.....but their methodological approach to looking at a problem/ invention is literally driving a Yugo, or some broken down old Buick


When I worked at Lexmark tech support long time ago, 20+ years ago, all my peers hated my guts, my problem solving "time per call of problem diagnosis" on high end complex business printers was typically 5X less than everyone else.
The managers kept monitoring my calls to wonder how the h3ll I was diagnosing 2000+ part business printers so much faster than everyone else was.
It really is that methodology.



You draw a circle around the problems, and move divergently AWAY from the problem, which is itself a CONVERGENCE to the center , the answer, thru DIvergence from the problems.

You can have DIvergent thoughts leading you from the center, the answer,...... looking for "a BILLION WAYS NOT TO MAKE A LIGHTBULB" (Sorry Edison, but you were a tinkering MORON!!!)
Great, you spend ENDLESS years eliminating the circle just to see/realize the center, which is very dumb.

Or you can realize the nature of ABCDEFG, the circle...... and have DIvergent thoughts FROM the circle (the non-answer) which is , logically necessitated to be so, CONVERGENT thoughts quickly bringing to to the center of the circle, the answer, the solution.


Divergent elimination is CONvergent synthesis (answers, solutions, discovery, invention).


Generically we think of 'divergent' as having useless thoughts going everywhere, but a different kind of divergence is used eliminatively to create a CONvergent 'mental vacuum' of comprehension into the answer of things we seek.




Edison was whacking weeds to invent........ Tesla ,mentally, was throwing gas on the BS and burning it leaving him with the answer.
This is HOW and WHY Tesla invented SO MUCH
and Edison invented , well, not so much


People have the brains and ignore the method. He11, method is 60% or more of the battle.

One thing I haven't been able to find any information about regarding the tower.
Was the intent to use AC or Pulsed DC?

[thx1138]

Read the patents

One thing I haven't been able to find any information about regarding the tower.
Was the intent to use AC or Pulsed DC?

If you will read the patents most everything is there. But be aware that his ideas changed over time and there are multiple patents at different times expressing different methodologies. Note that the dates given below are the application dates rather than the dates the patent was granted. This more closely tracks the point in time at which Tesla developed his idea to the point where it could be reduced to a patent. The date the patent was granted could be months or years after he filed the application.

1897-09-02 US Patent 645,576 System Of Transmission Of Electrical Energy proposes transmitting between tethered balloons maintained at "sufficient" altitude. His original intent was 15 miles high (79,200 feet) but by developing sufficient voltage he managaed to reduce that to 30,000 feet. make note of the date.

When he went to Colorado Springs in 1899 he was still intending to use the elevated balloons and there are notes about electrically extracting hydrogen from the atmosphere for this purpose. On July 4, 1899 he made some critical observations while watching the electrical discharges of lightning in a storm and detecting them with a "sensitive device". He even notes, "This is important!" Read these notes as well as the patents. The true importance didn't dawn on him immediately because on the next day, the July 5 notes talk about the hydrogen extraction for the balloons again.

Upon his return from Colorado Springs he filed another patent which still specifies using balloons at altitude.
1900-02-19 US 649,621 Apparatus For Transmission Of Electrical Energy
In this patent he clearly states that the transmission is via true conduction and not radiation. That relates to the altitude: at 30,000 feet the air is thin, the pressure is low, and it is very cold, roughly -40 degrees, all of which aid conduction. You also need to keep in mind the times. There were no airplanes. And at that time the jet stream winds of 250+ MPH were unknown which would probably have foiled his attempts to maintain the balloons at altitude with tethers. As far as I know he never attempted the transmission between balloons. If he had done so there would surely have been photographs of such an undertaking.

1900-03-21 US 685,012 Means For Increasing The Intensity Of Electrical Oscillations
This patent is a method of using "liquid air", i.e. supercooled liquid gas, to cool the coils to reduce resistance so higher frequncies may be attained - the precursor to superconductors. It also simulates maintaining the coils at altitude to achieve the cold temperatures.

1902-01-18 US 1,119,732 Apparatus For Transmitting Electrical Energy
This patent is generally accepted as the patent describing the Wardenclyffe Tower. It makes no mention of transmitting through the air or using elevated balloons. So I'm guessing that some time between the earlier patents, above, and this one it dawned on him the importance of his July 4, 1899 observations - that he could transmit through the ground without having to maintain the balloons at altitude. The patent above about cooling the coils being his method of bringing the cold of the upper atmosphere down to earth for his coils.

1906-04-17 Canadian Patent 142,352 Art Of Transmitting Electrical Energy Through Natural Mediums
This patent clearly states that the transmssions are to be through the earth and that he is reproducing the effects of lightning striking the earth and setting up standing waves from which signals and/or power may be extracted. This patent, being filed in Canada, would have been somewhat obscure in those days because one had to be physically present to examine it. Note also that this is after Wardenclyffe was abandoned. It contains a lot of detail.

So all of his transmission patents were to create and control the strength, timing, and location of man made lightning. His early patents reproducing a cloud to cloud lightning bolt and the later ones reproducing a cloud to ground lightning bolt. In his July 4, 1899 observations he noted that the storms moving away from him changed the nodal points of the standing waves. By producing the same in a fixed location with a fixed frequency he could engineer and control the locations of the nodes which would receive the transmissions.

It is a very worthwhile endeavor to read the actual patents rather than what people have said about them. All of the drawings of Wardenclyffe shooting bolts of electricity into the air are misleading and all the BS about an "ionized channel" to the ionosphere is absolutely wrong. Any discharges from the cupola of the tower would be losses and the transmission at height was to be "true conduction" between balloons maintained at an altitude where the air is rarefied, the pressure is low, and it is very cold thus making conduction much easier to attain.

In answer to your question (finally) it was pulsed DC or, as he called it in every patent "impulses" that were being transmitted, but at tens of millions of volts like lightning and sometimes exceeding that of lightning as he clearly states in the patents. More accurately described it would be the disruptive discharge of a capacitor (the cupola) through a spark gap(s) and into the ground creating a displacement current to be retrieved at a distant nodal point.

It didn't matter, however, how the capacitor was charged. Although AC would have been more efficient, I don't think he ever said specifically other than to say a "suitable source" or something to that effect. I saw a picture somewhere of the generator at Wardenclyffe but don't remember if it was said to be AC or DC. I suspect AC just because Tesla was doing it. Why would he use a DC generator after all the animosity with Edison? Also consider the size of the wire that would have been necessary to carry DC from the lab generator to the tower vs that needed to carry AC of the same magnitude and budget was an overriding concern in the developent of Wardenclyffe.

I'm beginnign to ramble. One of the keys to understanding what Tesla did is to read his patents, notes, articles, and lectures and not what others say about what Tesla did or meant to do.
