“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 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 does not believe in the existence of an “electron” as pictured by pop science — or, he maintains, through practical reasoning and experimentation, that if it can exist at all, it does so only in perfect vacuum.

“To account for its apparently small mass, science conceives the electron as a hollow sphere, a sort of bubble. Now, a bubble can exist in such a medium as a gas or liquid because its internal pressure is not altered by deformation. But if, as supposed, the internal pressure of an electron is due to the repulsion of electric masses, the slightest conceivable deformation must result in the destruction of the bubble!

“Just to mention another improbability, the force tending to tear an electron apart is, in pounds per square inch, represented by the staggering figure of 256,899 followed by twenty-one zeros — and this is 513,798,000,000,000,000,000 times greater that the tension that tungsten wire can withstand! And yet it does not burst! Not even when it is hurled against an obstacle with a speed hundreds of thousands times greater than that of a bullet!”

–Nikola Tesla

“A Famous Prophet of Science Looks Into the Future.” Popular Science Monthly, November, 1928.

“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.”

Nikola Tesla

“Nikola Tesla Tells of New Radio Theories.”New York Herald Tribune, September 22, 1929.

“The idea of the atom being formed of electrons and protons which go whirling round each other like a miniature sun and planets is an invention of the imagination, and has no relation to the real nature of matter.

“Virtually all progress has been achieved by physicists, discoverers and inventors; in short, devotees of the science which Newton and his disciples have been and are propounding.

“Personally, it is only efforts in this direction which have claimed my energies. Similar remarks might be made with respect to other modern developments of thought. Take, for example, the electron theory. Perhaps no other has given rise to so many erroneous ideas and chimerical hopes. Everybody speaks of electrons as something entirely definite and real. Still, the fact is that nobody has isolated it and nobody has measured its charge. Nor does anybody know what it really is.

“In order to explain the observed phenomena, atomic structures have been imagined, none of which can possibly exist.

Nikola Tesla

“Great Scientific Discovery Impends.“ The Sunday Star, Washington D.C., May 17, 1931.

“My ideas regarding the electron are at variance with those generally entertained. I hold that it is a relatively large body carrying a surface charge and not an elementary unit. When such an electron leaves an electrode of extremely high potential and in very high vacuum, it carries an electrostatic charge many times greater than the normal. This may astonish some of those who think that the particle has the same charge in the tube and outside of it in the air. A beautiful and instructive experiment has been contrived by me showing that such is not the case, for as soon as the particle gets out into the atmosphere it becomes a blazing star owing to the escape of the excess charge. The great quantity of electricity stored on the particle is responsible for the difficulties encountered in the operation of certain tubes and the rapid deterioration of the same.”

–Nikola Tesla

“Dynamic Theory Of Gravity.“ July 10, 1937(Prior to interviews with the press on his 81st birthday observance).

“Before the electron theory was advanced, I had established that radio-active rays consisted of particles of primary matter not further decomposable, and the first thing to find out was whether the sun is charged to a sufficiently high potential to produce the effects noted. This called for a prolonged investigation which culminated in my discovery that the sun’s potential was 216,000,000,000 volts and that all such large and hot bodies emit cosmic rays.

“While the origin and character of the rays observed near the earth’s surface had thus been sufficiently well ascertained, the so-called cosmic rays observed at great altitudes presented a riddle for more than twenty-six years, chiefly because it was found they increased with the height at a rapid rate. My investigations brought out the astonishing fact that the effects at high altitude are of an entirely different nature, having no relation whatever to cosmic rays. These are particles from celestial bodies at very high temperatures and charged to enormous electrical potentials.

“The effects at great elevations are due to waves of extremely small lengths produced by the sun in a certain region of the atmosphere. THIS IS THE DISCOVERY I WISH TO MAKE KNOWN. The process involved in the generation of the waves is the following: The sun projects charged particles constituting an electric current which passes through a conducting stratum of the atmosphere approximately ten kilometers (six miles) thick enveloping the earth. This is a transmission of electrical energy exactly as I illustrated in my experimental lecture in which one end of a wire is connected to an electric generator of high potential, its other end being free. In this case the generator is represented by the sun and the wire by the conducting air.”

“The passage of solar current involves the transference of electric charges from particle to particle with the speed of light, resulting in the production of extremely short and penetrating waves. As the air stratum mentioned is the source of the waves it follows that the so-called cosmic rays observed at great altitude must increase as this stratum is approached.”

“I had been constructing with my assistants the first high-frequency alternators (dynamos), of the kind now used for generating power for wireless telegraphy. At three o’clock in the morning I came to the conclusion that I had overcome all the difficulties and that the machine would operate, and I sent my men to get something to eat. While they were gone I finished getting the machine ready, and arranged things so that there was nothing to be done, except to throw in a switch.

“When my assistants returned I took a position in the middle of the laboratory, without any connection whatever between me and the machine to be tested. In each hand I held a long glass tube from which the air had been exhausted. “If my theory is correct,” I said, “when the switch is thrown in these tubes will become swords of fire.” I ordered the room darkened and the switch thrown in—and instantly the glass tubes became brilliant swords of fire.

“Under the influence of great exultation I waved them in circles round and round my head. My men were actually scared, so new and wonderful was the spectacle. They had not known of my wireless light theory, and for a moment they thought I was some kind of a magician or hypnotizer. But the wireless light was a reality, and with that experiment I achieved fame overnight.

“Following this success, people of influence began to take an interest in me. I went into “society,” and I gave entertainments in return; some at home, some in my laboratory–expensive ones, too. For the one and only time in my life, I tried to roar a little bit like a lion.

“But after two years of this, I said to myself, “What have I done in the past twenty-four months?” And the answer was, “Little or nothing.” I recognized that accomplishment requires isolation. I learned that the man who wants to achieve must give up many things—society, diversion, even rest—and must find his sole recreation and happiness in work. He will live largely with his conceptions and enterprises; they will be as real to him as worldly possessions and friends.”

The Greatest Scientific Experiments of All-Time

If you search the web for the greatest, or most famous experiments in history, no site will mention any of the many experiments conducted by Nikola Tesla. What you will find are wonderful, and very important experiments–like those of Isaac Newton, Galileo Galilee, William Harvey, Michael Faraday and Luigi Galvani, but nothing about Tesla, whose investigations into electricity make history’s more recognized experiments look like high school science. Many people today do not know that Nikola Tesla was one of the greatest experimental scientists of all-time.

Throughout the scientist’s investigations into high frequency phenomena, Tesla satisfied himself with a conclusion that an electrostatic field of sufficient intensity could fill a room and light wireless lamps. In 1891, he demonstrated this fact in a lecture given before the American Institute of Electrical Engineers, and left an audience of America’s greatest engineers spell-bound as he demonstrated by experiments a new theory of light. He showed that by connecting two large sheets of zinc to the terminals of a circuit with the sheets being spread apart about fifteen feet away from each other, he could create an electrostatic field between the two. The sheets served as condensers, and both received the charge of electricity from the wires connecting the sheets to the transformer. Tesla would then introduce vacuum tubes and place them between the zinc sheets, illuminating the tubes and lighting the room. He waved the vacuum tubes around like a Jedi showcasing the first light sabers, and the tubes continued to glow as long as they remained in the electric field. With these results, Tesla theorized that it was possible to use the earth as a conductor of energy, create an electrostatic field in it, and send power to distant parts of the globe. 

To further develop and prove his wireless theory, Tesla spent time in Colorado Springs, from June 1, 1899 to January 7, 1900, to research and experiment with high voltage and high frequency electricity. He chose Colorado Springs because of the high elevation and low air pressure suitable for experimenting with electricity. Also, because he was in such as open area compared to his lab in New York that he was free to experiment with any such desire of voltage and frequency. With his new and improved disruptive coils (Tesla Coils), which could produce electrical vibrations into the millions of horsepower, Tesla was set test the limits of electricity. 

It’s clear from his notes that his principal aim was to find ways to manipulate the forces of nature and to utilize them for the advancement of mankind. He expressed that he had three main goals:

  1. To develop a transmitter of great power.
  2. To perfect means for individualizing and isolating the energy transmitted.
  3. To ascertain the laws of propagation of currents through the earth and the atmosphere.

In his 7 months of work, Tesla obtained voltage and frequencies in the hundreds of millions of horse power, producing sparks over 100 feet in length. He sent energy through the earth to light multiple lamps which were placed dozens of miles away from his transmitter, and discovered stationary waves deriving from lightning discharges which his receiver could detect hundreds of miles away from his station–a discovery proving that power could indeed be transmitted through the earth. He also discovered that the earth, as a whole, had certain natural periods of vibrations, and by using his inventions he could impress electrical vibrations at the same periods upon it, and the globe would be thrown into oscillations of such nature that massive amounts of energy could be created, collected, and transmitted to any distance. This process is called constructive interference (the interference of two or more waves of equal frequencies resulting in mutual reinforcement and producing double the amplitude). By doing this repeatedly, and by using the massive amounts of energy unheard of before, Tesla was able to transmit energy from his transmitter all the way around earth and back to his receiver traveling at a mean velocity of 292,815 miles per second. Witnessing these experiments and measurements, space, according to Tesla, was completely annihilated.

Fully confident that he accomplished what he set out for, Tesla journeyed back to New York to patent improved apparatuses, and to build a new system on a much larger scale. This would lead to his World Wireless System, known as his Wardenclyffe Tower. Unfortunately, Tesla would not complete his dream of providing mankind with cheap, unlimited energy… But his legacy and his dream should live on through these experiments in Colorado Springs.

“My project was retarded by the laws of nature. The world was not prepared for it. It was too far ahead of time. But the same laws will prevail in the end and make it a triumphal success.”

[Fig. 2.] — Experiment to Illustrate the Capacity of the Oscillator For Producing Electrical Explosions of Great Power: The coil, partly shown in the photograph, creates an alternative movement of electricity from the earth into a large reservoir and back at a rate of one hundred thousand alternations per second. The adjustments are such that the reservoir is fulled full and bursts at each alternation just at the moment when the electrical pressure reaches the maximum. The discharge escapes with a deafening noise, striking an unconnected coil twenty-two feet away, and creating such a commotion of electricity in the earth that sparks an inch long can be drawn from a water main at a distance of three hundred feet from the laboratory.

image

[Fig. 3.] — Coils Responding to Electrical Oscillations: The picture shows a number of coils , differently attuned and responding to the vibrations transmitted to them through the earth from an electrical oscillator. The large coil on the right, discharging strongly, is tuned to the fundamental vibration, which is fifty thousand per second; the two larger vertical coils to twice that number; the smaller white wire coil to four times that number, and the remaining small coils to higher tones. The vibrations produced by the oscillator were so intense that they affected perceptibly a small coil tuned to the twenty-sixth higher tone.

image

[Fig. 4.] — Burning the Nitrogen of the Atmosphere: This result is produced by the discharge of an electrical oscillator giving twelve million volts. The electrical pressure, alternating one hundred thousand times per second, excites the normally inert nitrogen, causing it to combine with the oxygen. The flame-like discharge shown in the photograph measures sixty-five feet across.

image

[Fig. 5.] — Illustrating An Effect of An Electrical Oscillator Delivering Energy at a Rate of Seventy-Five Thousand Horse-Power: The discharge, creating a strong draft owing to the heating of the air, is carried upward through the open roof of the building. The greatest width across is nearly seventy feet. The pressure is over twelve million volts, and the current alternates one hundred and thirty thousand times per second.

image

[Fig. 6.] — Experiment Illustrating the Capacity on the Oscillator for Creating a Great Electrical Movement: The ball shown in the photograph, covered with a polished metallic coating of twenty square feet of surface, represents a large reservoir of electricity, and the inverted tin pan underneath, with a sharp rim, a big opening through which the electricity can escape before filling the reservoir. The quantity of electricity set in movement is so great that, although most of it escapes through the rim of the pan or opening provided, the ball or reservoir is nevertheless alternately emptied and filled to over-flowing (as is evident from the discharge escaping on the top of the ball) one hundred and fifty thousand times per second.

image

[Fig. 7.] — A double-exposure photograph of Tesla sitting in front of his electrical oscillator. Of course he’s not really sitting there with the machine on. He would die.

[Fig. 8.] — Experiment Illustrating an Inductive Effect of an Electrical Oscillator of Great Power: The photograph shows three ordinary incandescent lamps lighted to full candle-power by currents induced in a local loop consisting of a single wire forming a square of fifty feet each side, which includes the lamps, and which is at a distance of one hundred feet from the primary circuit energized by the oscillator. The loop likewise includes an electrical condenser, and is exactly attuned to the vibrations of the oscillator, which is worked at less than five percent of its total capacity.

image

[Fig. 9.] — Experiment Illustrating the Transmission of Electrical Energy Through the Earth Without Wire: The coil shown in the photograph has its lower end or terminal connected to the ground, and is exactly attuned to the vibrations of a distant electrical oscillator. The lamp lighted is in an independent wire loop, energized by induction from the coil excited by the electrical vibrations transmitted to it through the ground from the oscillator, which is worked only to five per cent. of its full capacity.
