“The superstitious belief of the ancients, if it existed at all, can therefore not be taken as a reliable proof of their ignorance, but just how much they knew about electricity can only be conjectured. A curious fact is that the ray or torpedo fish, was used by them in electro-therapy. Some old coins show twin stars, or sparks, such as might be produced by a galvanic battery. The records, though scanty, are of a nature to fill us with conviction that a few initiated, at least, had a deeper knowledge of amber-phenomena. To mention one, Moses was undoubtedly a practical and skillful electrician far in advance of his time. The Bible describes precisely and minutely arrangements constituting a machine in which electricity was generated by friction of air against silk curtains and stored in a box constructed like a condenser. It is very plausible to assume that the sons of Aaron were killed by a high tension discharge and that the vestal fires of the Romans were electrical. The belt drive must have been known to engineers of that epoch and it is difficult to see how the abundant evolution of static electricity could have escaped their notice.”

Nikola Tesla On His “World Wireless System”

“By this invention every live part of Mother Earth’s body would be brought into action. Energy will be collected all over the globe in amounts small or large, as it may exist, ranging from a fraction of one to a few horse power or more. Every waterfall can be utilized, every coal field made to produce energy to be transmitted to vast distances, and every place on earth can have power at small cost. One of the minor uses might be the illumination of isolated homes. We could light houses all over the country by means of vacuum tubes operated by high frequency currents. We could keep the clocks of the United States going and give every one exact time; we could turn factories, machine shops and mills, small or large, anywhere, and I believe could also navigate the air.

“One of the most important features of this invention will be the transmission of intelligence. It will convert the entire earth into a huge brain, capable of responding in every one of its parts. By the employment of a number of plants, each of which can transmit signals to all parts of the world, the news of the globe will be flashed to all points. A cheap and simple receiving device, which might be carried in one’s pocket, can be set up anywhere on sea or land, and it will record the world’s news as it occurs, or take such special messages as are intended for it. If you are in the heart of the Sahara your wife can telegraph you from Washington, and if the instrument is properly made you alone will get the message. A single plant of a few horse power could operate hundreds of such instruments, so that the invention has an infinite working capacity and will cheapen the transmission of all kinds of intelligence.”

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

We know that 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 that Einstein’s theory was true, 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 numerous observations, experiments and measurements, qualitative and quantitative.

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, thus demolishing one of the basic pillars of the structure of relativity. Also, in 1899, he conducted experiments at Colorado Springs where he sent currents from his transmitter around earth and back to his receiver traveling at a mean velocity of 292,815 miles per second. 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.

Whether you believe Tesla witnessed and measured such speeds or not, his statements should still be given due consideration. After all, both Einstein and Tesla were remarkable scientists, but Einstein relied on abstract mathematics to prove his theories while Tesla followed the scientific method like a religion and was solely dependent on actual experimentation too prove his. Tesla’s work and theories have yet to be proven wrong either.

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

“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.)

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.)

“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.)

“[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.)

“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.)

“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: THE FIRST JEDI

Method of Lighting Wireless Vacuum Tubes Devoid of Any Electrodes Placed In An Alternating Electrostatic Field.

In 1891, just before becoming an American citizen, Nikola Tesla was asked to lecture before the American Institute of Electrical Engineers at the Columbia University in New York. He performed experiments with alternating currents of very high frequency and left an audience of America’s greatest engineers spell-bound as he demonstrated a new theory of light. This lecture would be the first public demonstration of transmitting wireless energy, making Tesla the true father of radio and wireless power.

Throughout his investigations of alternating currents of very high frequency phenomena, Tesla satisfied himself with the conclusion that light bulbs using carbon filaments were inferior, and that an electric field of sufficient intensity could be made to fill a room and light electrodeless vacuum tubes. This was done by connecting two large sheets of zinc to the terminal of the circuit with the sheets being spread apart about fifteen feet away from each other. The sheets served as condensers, and both received the charge of electricity from the wires connecting the sheets to the transformer, creating an electric field between the two. 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.

He accomplished this by upping the speed of his dynamo, transforming his alternating currents into a continuous flow of static currents. This allowed him to pass a large amount of energy from sheet to sheet, or even through his body, without any harm. To help better explain this, direct currents carry an electric charge along a conductor which travel in one single direction, like a straight line, while the charge in AC alternate back and forth in waveform. Both are extremely dangerous! Static currents, on the other hand, are stationary with no movement. Tesla would speed up his AC so fast that they would transform into a static current, allowing him to create a static field of electricity capable of lighting his wireless bulbs.

The electrical wizard went on to show the absolute harmlessness of his electric system by passing thousands of volts of electricity through his body–lighting light bulbs and shooting sparks out of his finger tips.

These amazing demonstrations would set Tesla apart from the rest of the scientific world, and the inventor would be showered with awards and invitations from all around the world begging him to share his work.

“EARTH ELECTRICITY TO KILL MONOPOLY.”

***A Way to Harness Free Electric Currents Discovered by Nikola Tesla***

The World Sunday Magazine, March 8, 1896.

The World is on the eve of an astounding revelation. The conditions under which we exist will be changed. The end has come to telegraph and telephone monopolies with a crash. Incidentally, all the other monopolies that depend on power of any kind will come to a sudden stop. The earth currents of electricity are to be harnessed. Nature supplies them free of charge. The cost of power and light and heat will be practically nothing.

The scientist-electricians who have for years been trying to master the mystery of electrical earth currents with which the ground beneath your feet is filled, are on the threshold of success. The success of the experiments they have under way means much to them, but vastly more to the people. It means that if Nikola Tesla succeeds in harnessing the electrical earth currents and putting then to work for man there will be an end to oppressive, extortionate monopolies in steam, telephone, telegraphs and the other commercial uses of electricity, and that the grasping millionaires who have for two decades milked the people’s purse with electrical fingers will have to relinquish their monopoly.

Nikola Tesla has discovered the secret of the electric earth currents of nature, and they will be adapted to the use of man. He has succeeded in transmitting sound by the currents that make an electric riot of the earth. The transmission of power will follow. His experiments reduced to commercially practicable uses will be able to tap the electric currents of the earth and make them serve the purposes of industry and of trade just as a well digger over on Long Island taps water or a Pennsylvania miner opens a vein of coal. The mighty electrical energy that has been stored up in the earth for ages will be harnessed and made to move the machinery of men.

Electricity will be as free as the air. For the privilege of its use legislatures will not have to be bribed or men corrupted at the polls, and public boards will not have to be “seen” to bestow exclusive franchises upon corporations organized to use public property for purposes of private gain, and make the people pay the original cost of their investment and excessive charges for service in order to squeeze dividends out of copiously watered shares.

Monopolies for purveying steams power too will be forced to capitulate to free electricity, for with the latter manufactures will only have to connect their dynamos with the earth currents to set their machinery in motion. The successful adaptation of Tesla’s discovery will administer a death-blow to the most galling slavery that has ever yoked the activities of men to the treadmill of monopoly. Tesla is the wizard who is going to emancipate modern industries from the shackles of corrupting, dividend-grabbing, monopolistic corporations.

Sound travels with amazing speed, but electrical vibrations travel so swiftly that it is difficult to conjure up a figure which will graphically illustrate their speed. Here is one that will perhaps convey a vivid and lucid impression. In fancy place yourself at a table with a revolver in one hand and a finger of the other hand on the key of a telegraph instrument connected with a wire that girdles the globe seven times and laps over on the eighth turn a distance equal to 11,000 miles. Pull the trigger of the pistol and simultaneously press the telegraph key.  While the sound of the report of the revolver is traveling 1,100 feet the electrical impulse imparted by the pressure on the key will pass seven and a half times around the world through the wire with which the key is connected.

Sound travels 1,250 feet a second and electrical impulse 186,000 miles a second. If the electrical currents with which the earth is filled can be harnessed and put to work a new era in electricity will have dawned. It is to the mastering of the mystery of these earth currents and their adaptation that scientist like Tesla have been striving.

In the course of Tesla’s experiments it is reported he found that in the vicinity of large cities there were so many conflicting earth currents that satisfactory results could not be obtained. So he went out to Denver and near there found a better field for experimenting.  There he met a friend interested in electrical research. They went to Pike’s Peak.  Conspicuous among their baggage were two autoharps.

Tesla and his friend scaled the rugged sides of the peak. At an elevation agreed upon they separated. Tesla skirted the peak and on reaching a point precisely opposite the place at which he left his friend he stopped. The two experimenters, on a line drawn straight through the peak, were thus separated by four miles of stratified rock. The two autoharps had been very delicately attuned before the scientists parted, and a time fixed for Mr. Tesla’s comrade to play an air (also agreed upon) on the autoharp.

Tesla waited patiently the arrival of the appointed time. Then he connected his harp with the ground in such a way as to secure harmonic resonance with the earth current. The manner and medium of this connection are secrets. The receiving autoharp was equipped with a microphone. As the time approached for his friend on the other side of the peak to strum the appointed tune Tesla listened with rapt attention.

At last, as a tuning-fork responds to its harmonic note sounded on the strings of a piano, the autoharp in Mr. Tesla’s hands gave out the harmonic tunes of “Ben Bolt” which his companion at his station four miles away straight through the peak was plucking from the tense wires of his instrument. The experiment was a success. After many tunes had been played Tesla and his companion descended the peak. A statement of the facts and results of the experiment was written and attested before a notary public as a matter of scientific record.

The electric currents are in the earth. Their strength is great enough to furnish all the power and light man needs. Mr. Tesla has overcome the initial difficulty, and has located and tapped the earth’s currents. The rest will follow, as followed the telephone, Prof. Bell’s discovery of how to transmit speech over a wire.

Reposting this again because this was only 1896. Tesla went on a killing spree with electricity after this and proved his theories through experiments at Colorado Springs. Everything after 1899 was just Tesla trying to commercially bring it forth to the public.

The Greatest Scientific Experiments of All-Time

image

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. 1.] — Nikola Tesla’s building in Colorado Springs which he called his “Experimental Station.”

image

[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.

image

[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.
