Tesla Cosmic Ray Motor to Transmit Power ‘Round Earth.”

“I have harnessed the cosmic rays and caused them to operate a motive device,“ declared Nikola Tesla, famous scientist, in an interview last evening on the eve of his 76th birthday.

Tesla, who all his life has worked in seclusion and struggles to avoid publicity with all the vigor with which movie stars court it, permits a handful of “science writers” to violate the rules as a sort of birthday party.

It is very much of an ordeal to the tall, straight, meticulously attired gentleman whose inventions have been epoch-making and who is unable to understand why the public should be interested in him.

“Cosmic ray investigation is a subject that is very close to me. I was the first to discover these rays and I naturally feel toward them as I would toward my own flesh and blood,” said Dr. Tesla.

His statement is borne out by reference to clippings of interviews with him more than a quarter of a century ago in which he discussed “penetrating rays” and to which not much attention was given as no one was able to comprehend the nature of them as he discussed them.

“I have advanced a theory of the cosmic rays and at every step of my investigations I have found it completely justified.” said Dr. Tesla.

Dr. Tesla stated that the amount of power he was able to develop in the device was insignificant.

I asked him if its power output was of the same magnitude as that of Crookes’ radiometer, the device with four vanes in a glass tube that are rotated by sunlight, and which is often seen in jewelers’ windows. He stated that the power output was many thousand times that of a Crookes’ radiometer.

“The attractive features of the Cosmic rays is their constancy. They shower down on us throughout the whole 24 hours, and if a plant is developed to use their power it will not require devices for storing energy as would be necessary with devices using wind, tide or sunlight.”

“All of my investigations seem to point to the conclusion that they are small particles, each carrying so small a charge that we are justified in calling them neutrons. They move with great velocity, exceeding that of light.

“More than 25 years ago I began my efforts to harness the cosmic rays and I can now state that I have succeeded in operating a motive device by means of them.”

I was able to prevail upon Dr. Tesla to give me some idea of the principle upon which his cosmic ray motor works.

“I will tell you in the most general way,” he said. “The cosmic ray ionizes the air, setting free many charges—ions and electrons. These charges are captured in a condenser which is made to discharge through the circuit of the motor.”

“I have hopes of building my motor on a large scale, but circumstances have not been favorable to carrying out my plan.”

I asked Dr. Tesla if his plan for transmission of power between planets involved the use of cosmic rays, and he stated that the two projects have no connection whatever. He stated that he has continued his experimental work in the laboratory on the interplanetary power transmission project and is certain of its feasibility.

I also asked him if he is still at work on the project which he inaugurated in the ‘90’s of transmitting power wirelessly anywhere on earth. He is at work on it, he said, and it could be put into operation.

He at that time announced two principles which could be used in this project. In one the ionizing of the upper air would make it as good a conductor of electricity as a metal.In the other the power would be transmitted by creating “standing waves” in the earth by charging the earth with a giant electrical oscillator that would make the earth vibrate electrically in the same way a bell vibrates mechanically when it is struck with a hammer.

“I do not use the plan involving the conductivity of the upper strata of the air,” he said, “but I use the conductivity of the earth itself, and in this I need no wires to send electrical energy to any part of the globe.”

“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.”

“Ere many generations pass, our machinery will be driven by power obtainable at any point of the Universe…

“Throughout space there is energy. Is this energy static or kinetic? If static our hopes are in vain; if kinetic—and this we know it is, for certain—then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.“

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.

May the Fourth be with you!

Tesla Coil:

*Patent No. 462,418: 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.“

The Greatest Experiments In Scientific History

In Colorado Springs from June 1, 1899 to January 7, 1900, Nikola Tesla conducted experiments and research on high voltage and high frequency electricity to prove his theory of wireless energy transmission. Tesla’s 10 years of research, experiments, and demonstrations prior to his expedition was merely practice on a small scale compared to what he had planned for his station in Colorado. 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 high voltage and high frequency electricity. With his new and improved Tesla coils, which could produce electrical vibrations into the millions of horsepower, he 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, not only did he accomplish all three goals and prove his theory of wireless energy transmission, but he made some of the most remarkable experiments in scientific history. He obtained voltage and frequencies in the hundreds of millions of horse power–producing sparks over 100 feet in length, and sent energy through the earth to light multiple lamps which were placed dozens of miles away from his transmitter. He discovered stationary waves deriving from lightning discharges which his receiver could detect hundreds of miles away from his station. This discovery proved that power could indeed be transmitted through the earth. He also discovered that the earth, as a whole, had certain 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 frequency and phase, resulting in their mutual reinforcement and producing a single amplitude equal to the sum of the amplitudes of the individual waves). By doing this repeatedly, and by using the massive amounts of energy unheard of before, Tesla was able to transmit energy from his transmitter around earth and back to his receiver traveling at a mean velocity of 292,815 miles per second. Witnessing this experiment, 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 an even much larger scale than in Colorado. This would lead to his World Wireless System, known as his Wardenclyffe Tower. Unfortunately though, 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.

“I am unwilling to accord to some small-minded and jealous individuals the satisfaction of having thwarted my efforts. These men are to me nothing more than microbes of a nasty disease. 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.”

Nikola Tesla Describing His Idea of Transmitting Wireless Energy…

Nikola Tesla Describing His Idea of Transmitting Wireless Energy Through the Earth In 1893.

“I cannot stretch my imagination se far, but I do firmly believe that it is practicable to disturb by means of powerful machines the electrostatic condition of the earth and thus transmit intelligible signals and perhaps power. In fact, what is there against the carrying out of such a scheme? We now know that electric vibration may be transmitted through a single conductor. Why then not try to avail ourselves of the earth for this purpose? We need not be frightened by the idea of distance. To the weary wanderer counting the mile-posts the earth may appear very large, but to that happiest of all men, the astronomer, who gazes at the heavens and by their standard judges the magnitude of our globe, it appears very small. And so I think it must seem to the electrician, for when he considers the speed with which an electric disturbance is propagated through the earth all his ideas of distance must completely vanish.”
