Nikola Tesla explaining his “World Wireless System“ and how it differs from today’s radio and wireless technology.

(Pre-hearing interview with Nikola Tesla’s legal counsel in 1916 to protect his radio patents from the Guglielmo Marconi and the Marconi Company.)

Tesla:

“The idea was to put the coil, with reference to the primary, in an inductive connection which was not close—we call it now a loose coupling—but free to permit a great resonant rise. That was the first single step, as I say, toward the evolution of an invention which I have called my “Magnifying Transmitter.” That means, a circuit connected to ground and to the antenna, of a tremendous electromagnetic momentum and small damping factor, with all the conditions so determined that an immense accumulation of electrical energy can take place…

“I mean that you have to have in the circuit, inertia. You have to have a large self-inductance in order that you may accomplish two things: First, a comparatively low frequency, which will reduce the radiation of the electromagnetic waves to a comparatively small value, and second, a great resonant effect. That is not possible in an antenna, for instance, of large capacity and small self-inductance. A large capacity and small self-inductance is the poorest kind of circuit which can be constructed; it gives a very small resonant effect. That was the reason why in my experiments in Colorado the energies were 1,000 times greater than in the present antennae.

Legal Counsel:

“You say the energy was 1,000 times greater. Do you mean that the voltage was increased, or the current, or both?”

Tesla:

“Yes, both. To be more explicit, I take a very large self-inductance and a comparatively small capacity, which I have constructed in a certain way so that the electricity cannot leak out. I thus obtain a low frequency; but, as you know, the electromagnetic radiation is proportionate to the square root of the capacity divided by the self-induction. I do not permit the energy to go out; I accumulate in that circuit a tremendous energy. When the high potential is attained, if I want to give off electromagnetic waves, I do so, but I prefer to reduce those waves in quantity and pass a current into the earth, because electromagnetic wave energy is not recoverable while the earth current is entirely recoverable, being the energy stored in an elastic system.“

Legal Counsel:

“What elastic system do you refer to?”

Tesla:

“I mean this: If you pass a current into a circuit with large self-induction, and no radiation takes place, and you have a low resistance, there is no possibility of this energy getting out into space; therefore, the impressed impulses accumulate.”

Legal Counsel:

“Let’s see if I understand this correctly. If you have radiation or electromagnetic waves going from your system, the energy is wasted?”

Tesla:

“Absolutely wasted. From my circuit you can get either electromagnetic waves, 90 percent of electromagnetic waves if you like, and 10 percent in the current energy that passes through the earth. Or, you can reverse the process and get 10 percent of the energy in electromagnetic waves and 90 percent in energy of the current that passes through the earth.

“It is just like this: I have invented a knife. The knife can cut with the sharp edge. I tell the man who applies my invention, you must cut with the sharp edge. I know perfectly well you can cut butter with the blunt edge, but my knife is not intended for this. You must not make the antenna give off 90 percent in electromagnetic and 10 percent in current waves, because the electromagnetic waves are lost by the time you are a few arcs around the planet, while the current travels to the uttermost distance of the globe and can be recovered.

“This view, by the way, is now confirmed.  Note, for instance, the mathematical treatise of Sommerfeld, [*] who shows that my theory is correct, that I was right in my explanations of the phenomena, and that the profession was completely misled. This is the reason why these followers of mine in high frequency currents have made a mistake. They wanted to make high frequency alternators of 200,000 cycles with the idea that they would produce electromagnetic waves, 90 percent in electromagnetic waves and the rest in current energy. I only used low alternations, and I produced 90 percent in current energy and only 10 percent in electromagnetic waves, which are wasted, and that is why I got my results.“

[*] Editorial note: In 1909, Sommerfeld performed a theoretical analysis of the propagation of radio waves around the earth, solving for the problem of a vertical dipole over a finitely conducting homogeneous ground. He divided the expression for the resulting field into "space wave” and “surface wave” components. The surface wave part had nearly identical properties to a unique plane surface wave solution to James Clark Maxwell’s equations that had been identified by Jonathon Zenneck two years previously. The field amplitudes varied inversely as the square root of the horizontal distance from the source and decayed exponentially with height above the interface. [Sommerfeld, Arnold N., “Uber die Ausbreitung der Wellen in der drahtlosen Telegraphie,” Annalen der Physik, March 16, 1909 (vol. 28, no. 4), OP. 665-736.]

Legal Counsel:

“You spoke… about getting all of the energy from your transmitting into your recieving station by this method of yours. I do not understand how you can get all of it.”

Tesla:

“Oh, that is hardly true; I am speaking as a matter of principle. You never can get all the energy, because there is no such thing as a perfect apparatus.”

Legal Counsel:

“I did not mean it in that sense. I understand that there is, of course, always some loss, but my conception was that when you created a disturbance in the commercial condition of the earth at your transmitting station, that that extended out in all radial directions.”

Tesla:

“Yes, it did.”

Legal Counsel:

“And therefore how, at any given station, can you get more than a small fraction of that energy?”

Tesla:

“Pardon me you are mistaken… In my first efforts, of course I simply contemplated to disturb effectively the earth, sufficiently to operate instruments. Well, you know you must first learn how to walk before you can fly. As I perfected my apparatus, I saw clearly that I can recover, of that energy which goes in all directions, a large amount, for the simple reason that in the system i have devised, one that current got into the earth it had no chance of escaping, because my frequency was low; hence, the electromagnetic radiation was low. The potential, the electric potential, is like temperature. We might as well call potential electric potential. The earth is a vast body. The potential differences in the earth are small, radiation is very small. Therefore, I’d I pass my current into the earth, the energy of the current is stored there as electromagnetic momentum of the vibrations and is not consumed until I put a reciever at a distance, when it will begin to draw the energy and it will go to that point and nowhere else.”

Legal Counsel:

“Why is that, on your theory?”

Tesla:

“I will explain it by an analogue.

"Suppose that the earth were an elastic bag filled with water. My transmitter is equivalent to a pump. I put it on a point of the globe, and work my little piston so as to create a disturbance of that water. If the piston moves slowly, so that the time is long enough for the disturbance to spread over the globe, then what will be the result of my working this pump? The result will be that the bag will expand and contract rhythmically with the motions of the piston, you see. So that, at any point of that bag, there will be a rhythmical movement due to the pulsations of the pump.

"That is only, however, when the period is long. If I were to work this pump very rapidly, then I would create impulses, and the ripples would spread in circles over the surface of the globe. The globe will no longer expand and contract in its entirety, but it will be subject to these outgoing, rippling waves.

"Remember, now, that the water is incompressible, that the bag is perfectly elastic, that there are no hysteretic losses in the bag due to these expansions and contractions; and remember also, that there is a vacuum, in infinite space, so that the energy cannot be lost in waves of sound. Then, if I put at a distant point another little pump, and tune it to the rhythmical pulses of the pump at the central plant, I will excite strong vibrations and will recover power from them, sufficient to operate a receiver. But, if I have no pump there to receive these oscillations, if there is nowhere a place where this elastic energy is transferred into frictional energy (we always use in our devices frictional energy – everything is lost through friction), then there is no loss, and if I have a plant of 1,000 horsepower and I operate it to full capacity, that plant does not take power, it runs idle, exactly as the plant at Niagara. If I do not put any motors or any lamps on the circuit, the plant runs idle. There is a 5,000 horsepower turbine going, but no power is supplied to the turbine except such power as is necessary to overcome the frictional losses.

"Now the vast difference between the scheme of radio engineers and my scheme is this. If you generate electromagnetic waves with a plant of 1,000 horsepower, you are using 1,000 horsepower right along – whether there is any receiving being done or not. You have to supply this 1,000 horsepower, exactly as you have to supply coal to keep your stove going, or else no heat goes out. That is the vast difference. In my case, I conserve the energy; in the other case, the energy is all lost.”

Legal Counsel:

“Mr. Tesla, does that not presuppose that the fluid must be incompressible?”

Tesla:

“I should say so, and electricity, whatever it is, certainly it is incompressible because all our experiments show that.”

Legal Counsel:

“Now, if you were giving that a name, what principle would you say was involved by which the radiation loss, where there is no receiver, becomes a gain or a conservation where there is a receiver?”

Tesla:

“There is no radiation in this case. You see, the apparatus which I have devised was an apparatus enabling one to produce tremendous differences of potential and currents in an antenna circuit. These requirements must be fulfilled, whether you transmit by currents of conduction, or whether you transmit by electromagnetic waves. You want high potential currents, you want a great amount of vibratory energy; but you can graduate this vibratory energy. By proper design and choice of wave lengths, you can arrange it so that you get, for instance, 5 percent in these electromagnetic waves and 95 percent in the current that goes through the earth. That is what I am doing. Or you can get, as these radio men, 95 percent in the energy of electromagnetic waves and only 5 percent in the energy of the current. The apparatus is suitable for one or the other method. I am not producing radiation with my system; I am suppressing electromagnetic waves. In my system, you should free yourself of the idea that there is radiation, that the energy is radiated. It is not radiated; it is conserved.”

I saw a video on Youtube,saying that,a new Tesla Tower is built at Milford,Texas,U.S.A.,i don`t know if it is actually working yet,or the aims of it`s owners for future use of it.

Yes it’s being made by Viziv Technologies.

As Tesla explained above what his wireless system was intended to do, that is exactly what VT’s tower in Texas plans to do (to an extent at least I believe). From their website they claim, "Our Viziv surface wave system allows the Earth itself to be used for clean, safe and efficient transfer of power between any two points on the globe, wirelessly… The transition to a global wireless system utilizing the Zenneck surface wave is a breakthrough that will effectively “cut the cord” between power generation facilities and the local distribution grids. This breakthrough will significantly enhance energy surety, reliability, and resiliency of the world’s electrical distribution systems.”

Although they claim Jonathan Zenneck was the first known scientist to study electromagnetic wave propagation, my research on Nikola Tesla has proven that Tesla precedes him by over half a decade. Tesla actually meet and talked with Zenneck at one point and went over the calculations of his Sayville antenna and found that it was highly inefficient. So as this company praises Zenneck’s work, I hope they haven’t skipped over Tesla’s, who had a far better understanding.

I’m definitely going to keep following it though. Hope everything works for them. If not, at least it’s a start to bring us back to Tesla’s work.

Tesla Coil:

*Method of transformation of electrical energy by oscillatory condenser discharge. It was predicted that this apparatus afforded vast possibilities and would play an important part in the future.*

“This type of apparatus is identified with my name as certain as the law of gravitation is with that of Newton. I know that some have claimed that Professor Thomson also invented the so-called Tesla coil, but those feeble chirps ne’er went beyond Swampscott. Professor Thomson is an odd sort of man; very ingenious, but he never was a wireless expert; he never could be. Moreover, it is important to realize that this principle is universally employed everywhere. The greatest men of science have told me that this was my best achievement and, in connection with this apparatus I may say that a lot of liberties have been taken. For instance, a man fills this space [break D] with hydrogen; he employs all my instrumentalities, everything that is necessary, but calls it a new wireless system – the Poulsen arc. I cannot stop it. Another man puts in here [referring to space between self-inductive lines L L] a kind of gap – he gets a Nobel prize for doing it. My name is not mentioned. Still another man inserts here [conductor B] a mercury[-arc] rectifier. That is my friend Cooper Hewitt. But, as a matter of fact, those devices have nothing to do with the performance.

“If these men knew what I do, they would not touch my arrangements; they would leave my apparatus as it is. Marconi puts in here [break D] two wheels. I showed only one wheel; he shows two. And he says, “See what happens when the wheels are rotated; a wonderful thing happens!” What is the wonderful thing? Why, when the teeth of the wheels pass one another, the currents are broken and interrupted. That is the wonderful thing that happens? The Lord himself could not make anything else happen unless he broke his own laws. So, in this way, invention has been degraded, debased, prostituted, more in connection with my apparatus than in anything else. Not a vestige of invention as a creative effort is in the thousands of arrangements that you see under the name of other people – not a vestige of invention. It is exactly like in car couplings on which 6,000 patents have been taken out; but all the couplings are constructed and operated exactly the same way. The inventive effort involved is about the same as that of which a 30-year-old mule is capable. This is a fact.

“This is one of the most beautiful things ever produced in the way of apparatus: I take a generator of any kind. With the generator I charge a condensing. Then I discharged to condenser under conditions which result in the production of vibrations. Now, it was no sense Lord Kelvin that the condenser this charge would give this vibration, but I perfected my apparatus to such a degree that it became an instrument utilizable in the arts, In a much broader way than Lord Kelvin had contemplated as possible. In fact, years afterwards when Lord Kelvin honored me by presenting to the British Association one of my oscillators of a perfected form, he said that it was "a wonderful development and destined to be of great importance.”

The True Story of Nikola Tesla (In A Nutshell)

In the past, Direct Current was thought to be the future of power transmission. Then a young pimp named Nikola Tesla stepped in and showed that Alternating Current was the future. The inventor was ridiculed, bashed and attacked for years by Thomas Edison and his nut-hugging associates who were blinded by commercial interests. However, like a true playa, Tesla rose above the comp and proved that AC booty🍑 was far more superior than DC. Eventually, all scientists/inventors/engineers realized AC’s advantages to DC, and all the crony capitalists of the time instantly switched to AC to reap off Nik’s swagger. So while everyone else was finally catching up to the young pimp, Tesla finessed on to new discoveries in power transmission–world wireless power transmission. Nik Titties proved in numerous experiments throughout the late 1800s that energy could be transmitted wirelessly through the air, and or the earth, and power the world’s machinery. He did everything he could to share his advancement with the world, but unfortunately the commercial development of AC had taken full force, and the development of power transmission could not misdirect again like it had from DC to AC. The OG was pushed aside and ignored while the children played with his kid toys. So the Industrial Revolution progressed using Tesla’s primitive work, and now the world is a hundred years behind in development with no signs of returning back to the direction dreamed by NT.

And this… is the true story of Nikola Tesla (in a nutshell).

“The Singular Misconception of the Wireless.”

By Nikola Tesla

“Famous Scientific Illusions.” Electrical Experimenter, February, 1919.

“To the popular mind this sensational advance conveys the impression of a single invention but in reality it is an art, the successful practice of which involves the employment of a great many discoveries and improvements. I viewed it as such when I undertook to solve wireless problems and it is due to this fact that my insight into its underlying principles was clear from their very inception.

“In the course of development of my induction motors it became desirable to operate them at high speeds and for this purpose I constructed alternators of relatively high frequencies. The striking behavior of the currents soon captivated my attention and in 1889 I started a systematic investigation of their properties and the possibilities of practical application. The first gratifying result of my efforts in this direction was the transmission of electrical energy through one wire without return, of which I gave demonstrations in my lectures and addresses before several scientific bodies here and abroad in 1891 and 1892. During that period, while working with my oscillation transformers and dynamos of frequencies up to 200,000 cycles per second, the idea gradually took hold of me that the earth might be used in place of the wire, thus dispensing with artificial conductors altogether. The immensity of the globe seemed an unsurmountable obstacle but after a prolonged study of the subject I became satisfied that the undertaking was rational, and in my lectures before the Franklin Institute and National Electric Light Association early in 1893 I gave the outline of the system I had conceived. In the latter part of that year, at the Chicago World’s Fair, I had the good fortune of meeting Prof. Helmholtz to whom I explained my plan, illustrating it with experiments. On that occasion I asked the celebrated physicist for an expression of opinion on the feasibility of the scheme. He stated unhesitatingly that it was practicable, provided I could perfect apparatus capable of putting it into effect but this, he anticipated, would be extremely difficult to accomplish.

Figs. 5 & 6. — A Section of the Earth and Its Atmospheric Envelope Drawn to Scale. It is Obvious That the Hertzian Rays Cannot Traverse So Thin a Crack Between Two Conducting Surfaces For Any Considerable Distance. Without Being Absorbed, Says Dr. Tesla, in Discussing the Ether Space Wave Theory.

"I resumed the work very much encouraged and from that date to 1896 advanced slowly but steadily, making a number of improvements the chief of which was my system of concatenated tuned circuits and method of regulation, now universally adopted. In the summer of 1897 Lord Kelvin happened to pass through New York and honored me by a visit to my laboratory where I entertained him with demonstrations in support of my wireless theory. He was fairly carried away with what he saw but, nevertheless, condemned my project in emphatic terms, qualifying it as something impossible, “an illusion and a snare.” I had expected his approval and was pained and surprised. But the next day he returned and gave me a better opportunity for explanation of the advances I had made and of the true principles underlying the system I had evolved. Suddenly he remarked with evident astonishment: “Then you are not making use of Hertz waves?” “Certainly not,” I replied, “these are radiations. No energy could be economically transmitted to a distance by any such agency. In my system the process is one of true conduction which, theoretically, can be effected at the greatest distance without appreciable loss.” I can never forget the magic change that came over the illustrious philosopher the moment he freed himself from that erroneous impression. The skeptic who would not believe was suddenly transformed into the warmest of supporters. He parted from me not only thoroughly convinced of the scientific soundness of the idea but strongly exprest his confidence in its success. In my exposition to him I resorted to the following mechanical analogues of my own and the Hertz wave system.

"Imagine the earth to be a bag of rubber filled with water, a small quantity of which is periodically forced in and out of the same by means of a reciprocating pump, as illustrated. If the strokes of the latter are effected in intervals of more than one hour and forty-eight minutes, sufficient for the transmission of the impulse through the whole mass, the entire bag will expand and contract and corresponding movements will be imparted to pressure gauges or movable pistons with the same intensity, irrespective of distance. By working the pump faster, shorter waves will be produced which, on reaching the opposite end of the bag, may be reflected and give rise to stationary nodes and loops, but in any case, the fluid being incompressible, its inclosure perfectly elastic, and the frequency of oscillations not very high, the energy will be economically transmitted and very little power consumed so long as no work is done in the receivers. This is a crude but correct representation of my wireless system in which, however, I resort to various refinements. Thus, for instance, the pump is made part of a resonant system of great inertia, enormously magnifying the force of the imprest impulses. The receiving devices are similarly conditioned and in this manner the amount of energy collected in them vastly increased.

Fig. 7. — The Theory Has Been Seriously Advanced and Taught that the Radio Ether Wave Oscillations Pass Around the Earth by Successive Reflections, as Here Shown. The Efficiency of Such a Reflector Cannot be more than 25 Per Cent; the Amount of Energy Recoverable is a 12,000-mile Transmission being but One Hundred and Fifteen Billionth Part of One Watt, with 1.000 Kilowatts at the Transmitter.

"The Hertz wave system is in many respects the very opposite of this. To explain it by analogy, the piston of the pump is assumed to vibrate to and fro at a terrific rate and the orifice thru which the fluid passes in and out of the cylinder is reduced to a small hole. There is scarcely any movement of the fluid and almost the whole work performed results in the production of radiant heat, of which an infinitesimal part is recovered in a remote locality. However incredible, it is true that the minds of some of the ablest experts have been from the beginning, and still are, obsest by this monstrous idea, and so it comes that the true wireless art, to which I laid the foundation in 1893, has been retarded in its development for twenty years. This is the reason why the “statics” have proved unconquerable, why the wireless shares are of little value and why the Government has been compelled to interfere.

"We are living on a planet of well-nigh inconceivable dimensions, surrounded by a layer of insulating air above which is a rarefied and conducting atmosphere (Fig. 5). This is providential, for if all the air were conducting the transmission of electrical energy thru the natural media would be impossible. My early experiments have shown that currents of high frequency and great tension readily pass thru an atmosphere but moderately rarefied, so that the insulating stratum is reduced to a small thickness as will be evident by inspection of Fig. 6, in which a part of the earth and its gaseous envelope is shown to scale. If the radius of the sphere is 12½”, then the non-conducting layer is only 1/64″ thick and it will be obvious that the Hertzian rays cannot traverse so thin a crack between two conducting surfaces for any considerable distance, without being absorbed. The theory has been seriously advanced that these radiations pass around the globe by successive reflections, but to show the absurdity of this suggestion reference is made to Fig. 7 in which this process is diagrammatically indicated. Assuming that there is no refraction, the rays, as shown on the right, would travel along the sides of a polygon drawn around the solid, and inscribed into the conducting gaseous boundary in which case the length of the side would be about 400 miles. As one-half the circumference of the earth is approximately 12,000 miles long there will be, roughly, thirty deviations. The efficiency of such a reflector cannot be more than 25 per cent, so that if none of the energy of the transmitter were lost in other ways, the part recovered would be measured by the fraction (¼)30. Let the transmitter radiate Hertz waves at the rate of 1,000 kilowatts. Then about one hundred and fifteen billionth part of one watt is all that would be collected in a perfect receiver. In truth, the reflections would be much more numerous as shown on the left of the figure, and owing to this and other reasons, on which it is unnecessary to dwell, the amount recovered would be a vanishing quantity.

Fig. 8. — This Diagram Illustrates How, During a Solar Eclipse, the Moon’s Shadow Passes Over the Earth With Changing Velocity, and Should Be Studied In Connection With Fig. 9. The Shadow Moves Downward With Infinite Velocity at First. Then With Its True Velocity Thru Space, and Finally With Infinite Velocity Again.

"Consider now the process taking place in the transmission by the instrumentalities and methods of my invention. For this purpose attention is called to Fig. 8, which gives an idea of the mode of propagation of the current waves and is largely self-explanatory. The drawing represents a solar eclipse with the shadow of the moon just touching the surface of the earth at a point where the transmitter is located. As the shadow moves downward it will spread over the earth’s surface, first with infinite and then gradually diminishing velocity until at a distance of about 6,000 miles it will attain its true speed in space. From there on it will proceed with increasing velocity, reaching infinite value at the opposite point of the globe. It hardly need be stated that this is merely an illustration and not an accurate representation in the astronomical sense.

Fig. 9. — Theory.

"The exact law will be readily understood by reference to Fig. 9, in which a transmitting circuit is shown connected to earth and to an antenna. The transmitter being in action, two effects are produced: Hertz waves pass through the air, and a current traverses the earth. The former propagate with the speed of light and their energy is unrecoverable in the circuit. The latter proceeds with the speed varying as the cosecant of the angle which a radius drawn from any point under consideration forms with the axis of symmetry of the waves. At the origin the speed is infinite but gradually diminishes until a quadrant is traversed, when the velocity is that of light. From there on it again increases, becoming infinite at the antipole. Theoretically the energy of this current is recoverable in its entirety, in properly attuned receivers.

Fig. 10. — Tesla’s World-Wide Wireless Transmission of Electrical Signals, As Well As Light and Power, Is Here Illustrated in Theory, Analogy and Realization. Tesla’s Experiments With 100 Foot Discharges At Potentials of Millions of Volts Have Demonstrated That the Hertz Warn Are Infinitesimal In Effect and Unrecoverable: the Recoverable Ground Waves of Tesla Fly "Through the Earth”. Radio Engineers Are Gradually Beginning to See the Light and That the Laws of Propagation Laid Down by Tesla Over a Quarter of a Century Ago Form the Real and True Basis of All Wireless Transmission To-Day.

“Some experts, whom I have credited with better knowledge, have for years contended that my proposals to transmit power without wires are sheer nonsense but I note that they are growing more cautious every day. The latest objection to my system is found in the cheapness of gasoline. These men labor under the impression that the energy flows in all directions and that, therefore, only a minute amount can be recovered in any individual receiver. But this is far from being so. The power is conveyed in only one direction, from the transmitter to the receiver, and none of it is lost elsewhere. It is perfectly practicable to recover at any point of the globe energy enough for driving an airplane, or a pleasure boat or for lighting a dwelling. I am especially sanguine in regard to the lighting of isolated places and believe that a more economical and convenient method can hardly be devised. The future will show whether my foresight is as accurate now as it has proved heretofore.”

“Over five years have elapsed since that providential lightning storm on the 3rd of July, 1899, of which I told in the article before mentioned, and through which I discovered the terrestrial stationary waves; nearly five years since I performed the great experiment which on that unforgettable day, the dark God of Thunder mercifully showed me in his vast, awe-sounding laboratory. I thought then that it would take a year to establish commercially my wireless girdle around the world. Alas! my first “world telegraphy” plant is not yet completed, its construction has progressed but slowly during the past two years. And this machine I am building is but a plaything, an oscillator of a maximum activity of only ten million horse-power, just enough to throw this planet into feeble tremors, by sign and word—to telegraph and to telephone. When shall I see completed that first power plant, that big oscillator which I am designing! From which a current stronger than that of a welding machine, under a tension of one hundred million volts, is to rush through the earth! Which will deliver energy at the rate of one thousand million horse-power—one hundred Falls of Niagara combined in one, striking the universe with blows—blows that will wake from their slumber the sleepiest electricians, if there be any, on Venus or Mars! .  .  .  It is not a dream, it is a simple feat of scientific electrical engineering, only expensive—blind, faint-hearted, doubting world! .  .  .  Humanity is not yet sufficiently advanced to be willingly led by the discover’s keen searching sense. But who knows? Perhaps it is better in this present world of ours that a revolutionary idea or invention instead of being helped and patted, be hampered and ill-treated in its adolescence—by want of means, by selfish interest, pedantry, stupidity and ignorance; that it be attacked and stifled; that it pass through bitter trials and tribulations, through the heartless strife of commercial existence. So do we get our light. So all that was great in the past was ridiculed, condemned, combated, suppressed—only to emerge all the more powerfully, all the more triumphantly from the struggle.”

drnikolatesla:

Why Was Nikola Tesla One Of Albert Einstein’s Biggest Critics?

We know that Albert Einstein’s Theory​ of Special Relativity says that the kinetic energy (e) of a body equals its mass (m) times the speed of light (c²), or (e=mc²). The equation expresses a theory that mass and energy are the same physical entity and can be changed into each other. It also asserts that speeds greater than 186,300 miles per second (speed of light) are impossible in the universe. It is literally one of the principal tenets of the theory; that the mass of a body increases with its speed, and would become infinite at the velocity of light. Hence, a greater velocity is impossible.

Nikola Tesla positively denied Einstein’s theory, not just because he rejected the idea of matter being convertible into energy, and energy into matter, or even the existence of space-time, but because he himself had measured speeds traveling faster than light in many experiments, observations and measurements, both qualitative and quantitative throughout his lifetime of research.

As far back as 1896, Tesla conducted experiments on cosmic rays where he measured cosmic ray velocities from the star Antares, which he measured to be fifty times greater than the speed of light, literally demolishing one of the basic pillars of the structure of relativity. Also, in 1899, he conducted and recorded numerous experiments at Colorado Springs where he sent electrical currents from his transmitter around earth and back to his receiver traveling at a mean velocity of 292,815 miles per second. After these experiments, On April of 1900 he published a patent on this transmitter titled the “Art of Transmitting Electrical Energy Through the Natural Medium,” which was just a play thing compared to his Magnifying Transmitter patented in 1914. Also, in June of 1900, he published an article in the Century Magazine titled “The Problem of Increasing Human Energy,” where he outlined his experiments in Colorado Springs and his plans for the future.

Whether you believe Tesla witnessed and measured such speeds or not, his statements should still be given due consideration. After all, both Tesla and Einstein were genius minds, but Einstein was merely a theoretical physicist who relied on abstract mathematics and other scientist’s work to prove his theories, while Tesla followed the scientific method like a religion and was solely dependent on actual experimentation to prove his. Nikola Tesla’s work and theories have yet to be proven wrong to this day and are beginning to resurface as present science and technology improves.

Anyways… Here are 6 quotes from Tesla critiquing Einstein’s Theory of Relativity. Enjoy (((:

*Nikola Tesla reading James Clark Maxwell’s book, “The Scientific Papers,” in front of the spiral coil of his high-frequency transformer at East Houston St. 46, New York*

1. “What is ‘thought’ in relativity, for example, is not science, but some kind of metaphysics based on abstract mathematical principles and conceptions which will be forever incomprehensible to beings like ourselves whose whole knowledge is derived from a three-dimensional world.”  –NT  (“Great Scientific Discovery Impends.” Sunday Star. Washington D.C., May 17, 1931.)

2. We read a great deal about matter being changed into force and force being changed into matter by the cosmic rays. This is absurd. It is the same as saying that the body can be changed into the mind, and the mind into the body. We know that the mind is a functioning of the body, and in the same manner force is a function of matter. Without the body there can be no mind, without matter there can be no force. Einstein has for years developed formulas explaining the mechanism of the cosmos. In doing this he overlooked an important factor, namely the fact that some of the heavenly bodies are increasing in distance from the sun. This is the same as writing a business letter and forgetting the subject you wish to write about. In order to explain this phenomenon Einstein has invented the quantity “lambda.” My theory of gravitation explains this phenomenon perfectly.” –NT  (Tesla’s statement relating to force and matter, to Einstein’s theories, and Tesla’s own theory of gravitation. Courtesy of Nikola Tesla Papers. Rare Book and Manuscript Library, Columbia University. April 15, 1932.)

3. “I hold that space cannot be curved, for the simple reason that it can have no properties. It might as well be said that God has properties. He has not, but only attributes and these are of our own making. Of properties we can only speak when dealing with matter filling the space. To say that in the presence of large bodies space becomes curved, is equivalent to stating that something can act upon nothing. I, for one, refuse to subscribe to such a view.” –NT (“Pioneer Radio Engineer Gives Views On Power.” New York Herald Tribune, September 11, 1932.)

4. “[The Theory of Relativity] is a mass of errors and deceptive ideas violently opposed to the teachings of great men of science of the past and even to common sense. The theory wraps all these errors and fallacies and clothes them in magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king. Its exponents are very brilliant men, but they are metaphysicists rather than scientists. Not a single one of the relativity propositions has been proved.” –NT(“Tesla, 79, Promises to Transmit Force.” New York Times, July 11, 1935.)

5. “The kinetic and potential energy of a body is the result of motion and determined by the product of its mass and the square of velocity. Let the mass be reduced, the energy is diminished in the same proportion. If it be reduced to zero the energy is likewise zero for any finite velocity. In other words, it is absolutely impossible to convert mass into energy. It would be different if there were forces in nature capable of imparting to a mass infinite velocity. Then the product of zero mass with the square of infinite velocity would represent infinite energy. But we know that there are no such forces and the idea that mass is convertible into energy is rank nonsense…

“According to the relativists, space has a tendency to curvature owing to an inherent property or presence of celestial bodies. Granting a semblance of reality to this fantastic idea, it is still self-contradictory. Every action is accompanied by an equivalent reaction and the effects of the latter are directly opposite to those of the former. Supposing that the bodies act upon the surrounding space causing curvature of the same, it appears to my simple mind that the curved spaces must react on the bodies and, producing the opposite effects, straighten out the curves. Since action and reaction are coexistent, it follows that the supposed curvature of space is entirely impossible. But even if it existed it would not explain the motions of the bodies as observed. Only the existence of a field of force can account for them and its assumption dispenses with space curvature. All literature on this subject is futile and destined to oblivion. So are also all attempts to explain the workings of the universe without recognizing the existence of the ether and the indispensable function it plays in the phenomena.” –NT (“Dynamic Theory Of Gravity.” July 10, 1937. Prior to interviews with the press on his 81st birthday observance.)

6. “The relativity theory, by the way, is much older than its present proponents. It was advanced over 200 years ago by my illustrious countryman Boskovic, the great philosopher, who, not withstanding other and multifold obligations, wrote a thousand volumes of excellent literature on a vast variety of subjects. Boskovic dealt with relativity, including the so-called time-space continuum.” NT

Nikola Tesla aka “Mr. π / 2 ( c )”

v = π / 2 ( c )

v = average velocity of Tesla’s electrical current round earth (miles per second)

(you can plug in any metric and get same results)

c = speed of light (miles per second)

v = π / 2 (186,300)

v = 1.57 (186,300)

v = 292,491

While experimenting in Colorado Springs at the end of 1899, Nikola Tesla sent electrical currents around the earth faster than the speed of light. In his patent No. 787,412, filed May 16, 1900, titled the “Art of Transmitting Wireless Electrical Energy Through the Natural Mediums,” Tesla showed that the current of his transmitter passed over and around the earth’s surface with a speed of 292,815 miles per second. In his patent he says:

“The most essential requirement is that irrespective of frequency the wave or wave-train should continue for a certain period of time, which I have estimated to be not less than one-twelfth or probably 0.08484 of a second and which is taken in passing to and returning from the region diametrically opposite the pole over the earth’s surface with a mean velocity of about 471,240 kilometers per second [(292,815 miles per second)].”

Tesla held, however, that our present “wireless” technology (ex. Internet, WiFi, radio, etc.) are not true Hertzian waves, but act more like sound waves. They travel close to the speed of light and are purely radiation while his energy transmission through the earth gives off no radiation. Also, his energy is completely recoverable while other wireless transmissions are not. This is how Tesla theorized that he could send any amount of electrical energy through the earth to power the world’s machinery and technology.

So… Mr. “π / 2 ( c )” was, and still is a mind far ahead of his time!

“NIKOLA TESLA TELLS OF NEW RADIO THEORIES.”

An interview with Nikola Tesla

New York Herald Tribune, September 22, 1929.

Does Not Believe in Hertz Waves and Heaviside Layer, Interview Discloses

The model of a “Tesla Coil” which will be featured in the historic exhibit of the radio show reawakens interest in its inventor.

It is not generally appreciated that this curious apparatus, often associated with pretty or spectacular demonstrations of high voltage electricity, is really a fundamental part of modern radio. For all the tuning apparatus and circuits in every transmitting and receiving set are simply variations of Tesla coils and Tesla coil circuits.

It was for this invention, and other inventions and principles concerned with tuning, heterodyning, and the generation of continuous waves, which were made at least several years before the very first experiments of Marconi, that many of our most reputable engineers have conceded to Nikola Tesla the title of “Father of Radio”.

Mr. Tesla, still actively working, was interviewed last week to get his ideas regarding the prospects of the radio of 1930, and beyond. As a prophet, however, he balked. He had repeated time and again his visions for the future. As far back as 1900, he had contemplated a world-wireless system which included broadcasting, picture transmission, international time service, and in addition television and the distribution of electrical power. Part of this early prophecy has been realized – what remained, still stood as his prediction.

Disputes Hertz Waves

What, then, about power transmission by radio? Laurence M. Cockaday, the technical editor of this radio section, had expressed the opinion several weeks ago that, with present apparatus at least, it was hardly feasible. Mr. Tesla agreed to discuss the point at length.  As a result, he made public for the first time one of the most extraordinary conclusions – that Hertz waves do not exist! If his theory is true, there may be found in it more adequate explanations of “dead spots”, fading, reflection and a dozen other problems that have always puzzled the profession.

The inventor began by referring to Cockaday’s article:

“I have read the article, and I quite agree with the opinion expressed – that wireless power transmission is impractical with present apparatus. This conclusion will be naturally reached by any one who recognizes the nature of the agent by which the impulses are transmitted in present wireless practice.

“When Dr. Heinrich Hertz undertook his experiments from 1887 to 1889 his object was to demonstrate a theory postulating a medium filling all space, called the ether, which was structureless, of inconceivable tenuity and yet solid and possessed of rigidity incomparably greater than that of the hardest steel. He obtained certain results and the whole world acclaimed them as an experimental verification of that cherished theory. But in reality what he observed tended to prove just its fallacy.

“I had maintained for many years before that such a medium as supposed could not exist, and that we must rather accept the view that all space is filled with a gaseous substance. On repeating the Hertz experiments with much improved and very powerful apparatus, I satisfied myself that what he had observed was nothing else but effects of longitudinal waves in a gaseous medium, that is to say, waves, propagated by alternate compression and expansion. He had observed waves in the ether much of the nature of sound waves in the air.

“Up to 1896, however, I did not succeed in obtaining a positive experimental proof of the existence of such a medium. But in that year I brought out a new form of vacuum tube capable of being charged to any desired potential, and operated it with effective pressures of about 4,000,000 volts. I produced cathodic and other rays of transcending intensity. The effects, according to my view, were due to minute particles of matter carrying enormous electrical charges, which, for want of a better name, I designated as matter not further decomposable. Subsequently those particles were called electrons.

"One of the first striking observations made with my tubes was that a purplish glow for several feet around the end of the tube was formed, and I readily ascertained that it was due to the escape of the charges of the particles as soon as they passed out into the air; for it was only in a nearly perfect vacuum that these charges could be confined to them. The coronal discharge proved that there must be a medium besides air in the space, composed of particles immeasurably smaller than those of air, as otherwise such a discharge would not be possible. On further investigation I found that this gas was so light that a volume equal to that of the earth would weigh only about one-twentieth of a pound.

"The velocity of any sound wave depends on a certain ratio between elasticity and density, and for this ether or universal gas the ratio is 800,000,000,000 times greater than for air. This means that the velocity of the sound waves propagated through the ether is about 300,000 times greater than that of the sound waves in air, which travel at approximately 1,085 feet a second. Consequently the speed in ether is 900,000 x 1,085 feet, or 186,000 miles, and that is the speed of light.

"As the waves of this kind are all the more penetrative the shorter they are, I have for years urged the wireless experts to use such waves in order to get good results, but it took a long time before they settled upon this practice.

"Although the world is still skeptical as to the feasibility of my undertaking, I note that some advanced experts, at least, share my views, and I hope that before long wireless power transmission will be as common as transmission by wires.”

According to Mr. Tesla, the present broadcasting station does not propagate Hertzian waves, as has always been supposed, but acts more like an “ether whistle” – transmitting waves through the ether similar to the waves transmitted by an ordinary whistle through the air. He also expressed his disbelief in the Heaviside layer, and claimed that the reflection of waves back toward the earth was due to the change of medium encountered at the vacuous boundary of the atmosphere.

At Colorado Springs, about thirty years ago, this scientist had a Tesla coil seventy-five feet in diameter which produced voltages above 12,000,000, and sparks over 100 feet long. Electrical flashes were created which were the nearest approach to lightning that man has ever made. During his experiments there, of over a year, Tesla claims that he transmitted a considerable amount of electrical current to the other side of the earth. It was upon these, and later experiments that he bases his present prediction.

If only he wasn’t blackballed by Edison… 😢

And the U.S. Government.
