Here it is the imaginative rarefaction through electric discharges of Special Coils.
Tesla coil is the name of one of the most astounding inventions of the Serb scientist Nikola Tesla.
It’s an electric equipment that can generate electrostatic disruptive discharges at high frequencies and very high voltages, the Tesla coil, built and operated by masque, will transform the lightness of human posture in a Prometheus of the lightning.

When we first heard about the incredibile history of Nikola Tesla, it often came to our minds that we could be dealing with a sort of urban legend: how was it possible that the man who created the first power station of the world by harnessing the Niagara falls, would be a complete stranger and would be left in a corner of the scientific and human history of the past century, century of which he surely was the protagonist?
It didn’t seem to contribute to the fame of the Serb scientist the fact that he invented the three-phase system of electric power distribution that we use nowadays to fuel our industries and our houses, and that he owned the patents of the first alternating current motor and of the first appliance for radio transmission (until the sensational recognition, in 1943, from the Supreme Court of the United States, of the authorship of the invention of the radio, to the detriment of the Italian Guglielmo Marconi).
To the question about who is the greatest hacker of all times, someone could answer Adrian Lamo, others Kevin Mitnick, others Steve Wozniak from Apple or Richard Stallman from Massachusetts Institute of Technology, but we can assert without the shadow of a doubt that it was Nikola Tesla.

When the first lightning detached itself (115 cm in lenght, quite small compared to the ones produced by Tesla in his Colorado Springs laboratory, where he established the record of the longest lightning ever created by man, of 260 feet, more or less 80 metres) from the first Tesla coil built and operated by Masque,  it was clear that many of the “urban legends” about the Serb scientist were truths. It was also evident that the reason for that violent and ferocious disregard was due to the exceptionality of the inventions and the theories of Nikola Tesla, that were far ahead of its time, but above all, they were openly conflicting with the newborn American electric industry that Tesla himself had so strongly helped in getting started. Coming back from Colorado Springs, were he patented his discoveries about wireless transmission of energy, during a meeting with the famous banker J. P. Morgan, whom the inventor contacted to ask for financial support for the construction of his global system of wireless transmission of energy, Tesla proposed an idea of what the “global system” would have offered to humanity, underlining the advantages of the possibility to transmit electric power wireless everywhere on the Earth. Tesla accepted the 150.000 dollars that J. P. Morgan offered, in exchange for the 51% over his patents on wireless transmission of electric power. But J. P. Morgan was also the major financer of General Electric and of Westinghouse (the two multinationals controlled 90% of the market of the “cable” distribution of electric power). Before Tesla could complete his appliance of Wardenclyffe, in Shoreham, on Long Island –New York State –a 80-meter tower, designed by the famous architect White, was built, and the future of the great inventor was doomed. The trap that J. P. Morgan had set for Tesla had worked well. At 48 (the New York stock exchange announced the failure of Tesla’s project of Global transmission after J. P. Morgan declared he won’t have refinanced it) Tesla was finished. He will die at 86, alone in a New York hotel, but not before he could patent the “Death ray” that was used, few years ago, in the creation of the American Strategic Defense Initiative. The day after Nikola Tesla’s death, FBI put the seal “TOP SECRET” on the 20 boxes containing his various projects and devices.

But let’s come back to his most famous invention, the Tesla coil that can produce electrostatic disruptive currents of a million of volts. Here we will explain how it works. Many people think that the earth isn’t a good conductor. In reality, tha earth can absorb great quantities of electricity, and this is the reason why every electric appliance is earthed: the third terminal (the central one) in alternating current plugs has a wiring that makes it disperse into the ground.
In Colorado Springs, Tesla succeeded in a never before attempted enterprise: he used the whole planet as a conductor, making an electric discharge go through it. In other words, Tesla created a powerful electric power discharge and earthed it. Since it’s a good conductor, the current didn’t stop, in fact going on propagating like a radio wave at light’s speed: 300.000 km per second. The wave continued advancing: it was powerful, and it didn’t weaken even at miles’ distance…it crossed without any problem even the centre of the Earth…after all, molten iron is a perfect conductor for electricity! When the wave reached the other side of the planet, it came back , just like it does any wave facing an obstacle.
Every time it set off, it came back, and at times it reached again the starting point. Even if the idea could seem odd, it isn’t science fiction. Our planet has a 4000 km diameter: to have an electromagnetic wave crossing it’s a child’s play!
When the wave comes back (around 1/30 of a billionth of a second after it has been sent), its power has considerably decreased: so Tesla thought, why not send a second one to strenghten the first one? The two merge, react and go back, and the wave becomes more and more powerful. It’s just like pushing a swing every time it comes back: the power increases greatly with a series of small pushes.

Coming back to the latest machine we created, this is the way in which the electric tension of the principal transformers (15.000 volts in our Tesla Coil) is increased, in the so-called magnifying resonant transformer, up to around a million volts!  And we should keep in mind that 3000 volts are necessary to go through a millimeter of air.

Now, I would like to let you know I’ve realized one of the first experiments that can confirm the experience of the wireless transmission of energy… The distance covered by this transmission, up to now, isn’t more than 4,5 meters: we are currently building a system including two coils of great dimensions so to achieve a distance of transmission of 10/13 meters.
To make it clear the importance of the experiment we should act with extreme clarity and precision: during that experiment, after having shown and operated a Tesla Coil that produces a million volts and an arc to the terminal of the coil itself of around 100 cm, I accompanied the public to the courtyard in front of the room of the lecture: here one of my assistants dug  (live) a conductive bar of 170 cm into the ground.

Then we brought on the “scene” first the receiving coil (made of a winding of around 1000 wire coils and surmounted by a sphere of conductive material) and after, at a distance of around 2 meters, the transmitting coil (identical in shape).
One end of a bulb socket that holds two incandescent light bulbs of 25 watts each, is directly connected to the earth wire connected to the bar dug into the ground. At the other end of the bulb socket is the terminal of the winding of the receiving coil.
It’s worth noticing that the system made up of the bulb socket and the receiving coil forms a system that is completely insulated from the generator that is placed at a two-meters distance.
The two coils are attuned to the same resonant frequency (around 236.000 Hz).
Using a generator that allows to change the frequency from 150.000 Hz to 280.000 Hz, when the resonant frequency of the coils is reached (236.000 Hz) we can see a transmission via “ether” of electric power: the two incandescent light bulbs will brightly turn on.

Of course it’s not a real wireless transmission, since Tesla understood he could use the earth as a global conductor. Here is a photo of the work station: at the ends of the table, the two Tesla coils. At the right of the viewer the transmitting coil, at the left the receiving one.

The receiving coil (as well as the transmitting) is made up of a winding of around 1000 copper coils that is treated with insulating varnish: the end of which is directly connected to one end of the bulb. The other end (and this is the extraordinary thing) is tied directly to the earth!
