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.)


“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?”


“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?”


“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?”


“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.

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.”


“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.”


“Yes, it did.”

Legal Counsel:

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


“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?”


“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?”


“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?”


“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.


Nikola Tesla was asked how long would it take for the transmission of energy, by his system, to travel around the world?

“The exact time is, according to my measurements, 43-1000 of a second, which is a speed about 50 per cent greater than that of light.

“The impulse starts from my magnifying transmitter with infinite speed, slows first rapidly and then at a lesser rate until, when it has penetrated to a distance of 6000 miles from the transmitter, it proceeds with approximately the speed of light. From there on it accelerates, first slowly and then more rapidly, and reaches the opposite point of the globe again with infinite speed only to rebound and pass through the same phases on its way back to the transmitter.

“This movement of electricity through the Earth, which takes place strictly in accordance with a mathematical law, and enables a great number of accurate measurements and determinations to be made, which are of immense practical and scientific value.”

–Nikola Tesla

*Nikola Tesla’s remarkable experiments with wireless lamps and vacuum tubes shown before the Franklin Institute and the National Electric Light Association in 1893*

“These were the most striking results I showed in the transmission of energy… You see how far I have gone into the mastery of electrical vibrations in 1893. I stand here [Fig. 190] in the hall, holding a lamp in my hand, and the energy transmitted lights it. Here again [Fig. 191] I hold a phosphorescent bulb in my hand, and here [Fig. 192] a vacuum tube.

"These experiments, I remember, were made in St. Louis. There was a hall with 6,000 or 7,000 people. When I explained how I had shown a phosphorescent bulb to Lord Kelvin in England, and told them that the bulb was going to spring into light, and the current was turned on and it did burst into light, there was a stampede in the to upper galleries and they all rushed out. They thought it was some part of the devil’s work, and ran out. That was the way my experiments were received.”

An Inventor’s Seasoned Ideas

Nikola Tesla, Pointing to ‘Grievous Errors’ of the Past, Explains Radio as He Sees It at Age of 77 — He Expects Television

By Orrin E. Dunlap Jr.

A tall, lean inventor in a cut-away walked into his skyscraper parlor thirty-three floors above the sidewalks of New York, laid his black derby on the table, opened the window and then was ready to talk about radio’s past, present and future. He was Nikola Tesla, the inventor whose discovery of the rotary magnetic field made possible the alternating-current motor. He described a system of wireless transmission of energy in 1892.

Seven milestones beyond three-score and ten, this electrical wizard, who came to America in 1884, looked back across the years, recalled where theorists often chose wrong paths at the crossroads of science and then turned his thoughts to the future in which television lurks.

A Spectacle That Frightens.

There is something frightening about the universe when we consider that only our senses of sound and sight make it beautiful,” said Mr. Tesla as his furrowed brow indicated he is puzzled with its destiny. “Just think, the universe is darker than the darkest ink; colder than the coldest ice and more silent than a silent tomb, with all the bodies rushing through it at terrific speeds. What an awe-inspiring picture, isn’t it? Yet it is our brain that gives merely a physical impression. Sight and sound are the only avenues through which we can perceive it all. Often I have wondered if there is a third sense which we have failed to discover. I’m afraid not,” he said after some hesitation in thought.

Looking back to the mauve decade, to the turn of the century when the world was being thrilled with new ideas and discoveries, Mr. Tesla observes a vast change in the art of invention. Man, he finds, in this streamline era of speed, has little chance to think.

Fruits of Seclusion.

The big, modern research laboratories are but the incubators of ideas as he has watched them function. Seldom, if ever, he explains, has an original idea of any consequence been born in an elaborate laboratory. The egg of science is laid in the nest of solitude. True, it may later be incubated, hatched and nursed in the million-dollar laboratory.

It is providential that the youth or man of inventive mind is not ‘blessed’ with a million dollars,” said Mr. Tesla. “He would find it difficult to think. The mind is sharper and keener in seclusion and uninterrupted solitude. No big laboratory is needed in which to think. Originality thrives in seclusion free of outside influences beating upon us to cripple the creative mind. Be alone, that is the secret of invention; be alone, that is when ideas are born. That is why many of the earthly miracles have had their genesis in humble surroundings.”

Radio experimenters of this age are following ancient theories, Mr. Tesla believes, and he warns that progress will be more rapid when they discard the old and adopt new ideas. His directions for getting on the right track of radio, television, power transmission by wireless and sundry other branches of science follow:

“The fascination of the electro-magnetic theory of light, advanced by Maxwell and subsequently experimentally investigated by Hertz, was so great that even now, although controverted, the scientific minds are under its sway. This theory supposed the existence of a medium which was solid, yet permitted bodies to pass through it without resistance; tenuous beyond conception, and yet, according to some, one thousand times denser than platinum. According to our conceptions of mechanical principles and ages of experience, such a medium was absolutely impossible. Nevertheless, light was considered essentially a phenomenon bound up in that kind of a medium; namely, one capable of transmitting transverse vibrations lite a solid.”

A Question Tesla Asked.

It is true,” said Mr. Tesla, “that many scientific minds envisaged the theory of a gaseous ether, but it was rejected again and again because in such a medium longitudinal waves would be propagated with infinite velocity. Lord Kelvin conceived the so-called contractile ether, possessing properties which would result in a finite velocity of longitudinal waves. In 1885, however, an academic dissertation was published by Professor De Volson Wood, an American, at a Hoboken institution, which dealt with a gaseous ether in which the elasticity, density and specific heat were determined with rare academic elegance. But, so far, everything pertaining to the subject was purely theoretical.

“What, then, can light be if it is not a transverse vibration?” That was the question he asked himself and set out to find the answer.

I consider this extremely important,” said Mr. Tesla. “Light cannot be anything else but a longitudinal disturbance in the ether, involving alternate compressions and rarefactions. In other words, light can be nothing else than a sound wave in the ether.

“This appears clearly,” Mr. Tesla explained, “if it is first realized that, there being no Maxwellian ether, there can be no transverse oscillation in the medium. The Newtonian theory, he believes, is in error, because it falls entirely in not being able to explain how a small candle can project particles with the same speed as the blazing sun, which has an immensely higher temperature.”

We have made sure by experiment,” said Mr. Tesla, “that light propagates with the same velocity irrespective of the character of the source. Such constancy of velocity can only be explained by assuming that it is dependent solely on the physical properties of the medium, especially density and elastic force.“

Micro-Wave Possibilities.

Coming now to the wireless waves, it is still true that they are of the same character as light waves, only they are not transversal but longitudinal. As a matter of fact, radio transmitters emit nothing else but sound waves in the ether, and if the experts will realize this they will find it very much easier to explain the curious observations made in the application of these waves.

It being a fact that radio waves are essentially like sound waves in the air, it is evident that the shorter the waves the more penetrative they would be. In 1899 I produced electromagnetic waves from one to two millimeters long and observed their actions at a distance. There has been a great hope expressed by various workers that introduction of these waves will have a revolutionary effect, but I am not sharing the opinion. They will be used, of course, but to a very limited extent. It is manifest that applications of the very short waves will not produce any appreciable effect upon the wireless art.”

“Errors” Retard Wireless Power.

What about the possibilities of power transmission by wireless? the inquirer said.

Here again Mr. Tesla blames “a strange misconception of the experts” and “grievous errors” for retarding the idea. He believes that when it is accomplished, the power will travel on long waves and not on the wings of “uneconomically produced” short waves. He said he could vouch that the scheme of wireless power transmission is entirely practical.

The application of short waves for power purposes,” said Mr. Tesla, “involves complicated and expensive apparatus for rectification or frequency transformation, which would make any serious attempt to carry out a project of this kind much more difficult from an economical point of view.“

When will television come around the corner? he was asked.

It ought to be with us soon, and some day it will be on a par of perfection with broadcasting of music.” Then with a circular sweep of his arm and added, “There will be large pictures thrown on the wall.”



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.

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.”

–Nikola Tesla

“The Transmission of Electrical Energy Without Wires As a Means for Furthering Peace.“ Electrical World and Engineer, January 7, 1905



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!
