NIKOLA TESLA Y SU RELACION CON EL EXPERIMENTO FILADELFIA - DESENMASCARANDO LAS FALSAS DOCTRINAS

Picture a reclusive man, dripping with sweat all night in a dark lab, illuminated only by crackling sparks that periodically leap from enormous machines and cast a purple glow across his face. This was Nikola Tesla, the archetype of the mad scientist. His inventions fill the world around us; they are instrumental to our modern electrical grid. They are quiet, reliable, invisible machines.

Perhaps his most famous invention is the Tesla coil – a contraption that produces beautiful flying arcs of electrical energy. It was invented by Tesla in an attempt to transmit electricity wirelessly.

Transformer in action

The principles behind the Tesla coil are relatively simple. Just keep in mind that electrical current is the flow of electrons, while the difference in electric potential (voltage) between two places is what pushes that current. Current is like water, and voltage is like a hill. A large voltage is a steep hill, down which a stream of electrons can rapidly flow. A small voltage is like a near-flat plain with almost no water flow.

The power of the Tesla coil lies in a process called electromagnetic induction. This is where a changing magnetic field creates a voltage that compels current to flow. In turn, the flowing electric current generates a magnetic field. When electricity flows through a wound up coil of wire, it generates a magnetic field that fills the area around the coil in a particular pattern.

Similarly, if a magnetic field flows through the centre of a coiled wire, a voltage is generated in the wire, which causes an electrical current to flow.

The voltage (“hill”) generated in a coil of wire by a magnetic field through its centre increases with the number of turns of wire. A changing magnetic field within a coil of 50 turns will generate ten times the voltage of a coil of just five turns. (However, less current can actually flow through the higher potential, to conserve energy.)

This is exactly how a common alternating current (AC) electrical transformer, found in every home, works. The constantly fluctuating electric current flowing in from the power grid is wound through a series of turns around an iron ring to generate a magnetic field. Iron is magnetically permeable, so the magnetic field is almost entirely contained in the iron. The ring guides the magnetic field (in green to the right) around and through the centre of the opposite coil of wire.

The ratio of coils on one side to the other determines the change in voltage. To go from 120V household wall voltage to, say, 20V for use in a laptop power adaptor, the output side of the coil will have six times fewer turns to cut the voltage to one sixth its original level.

How the coil rolls

Tesla coils do the same thing, but with a much more dramatic change in voltage. First, they employ a pre-made high voltage iron core transformer to go from 120V wall current to roughly 10,000V. The wire with 10,000 volts is wrapped into a large (primary) coil with only a handful of turns. The secondary coil contains thousands of turns of thin wire. This steps up the voltage to between 100,000 and 1,000,000 volts. This potential is so strong that the iron core of a normal transformer cannot contain it. Instead, there is only air between the coils.

The Tesla coil requires one more thing: a capacitor to store charge and fire it all in one huge spark. The circuit of the coil contains a capacitor and a small hole called a spark gap. When the coil is turned on, electricity flows through the circuit and fills the capacitor with electrons, like a battery. This charge creates its own electric potential in the circuit, which tries to bridge across the spark gap. This can only happen when a large amount of charge has built up in the capacitor.

Eventually so much charge has accumulated that it breaks down the electrical neutrality of the air in the middle of the spark gap. The circuit closes for a fleeting second and a huge amount of current blasts out of the capacitor and through the coils. This produces a very strong magnetic field in the primary coil.

The secondary wire coil uses electromagnetic induction to convert this magnetic field to an electric potential so high that it can easily break apart the air molecules at its ends and push their electrons in wild arcs, producing enormous purple sparks. The dome on the top of the device acts to make the secondary coil of wires receive energy more fully from the first coil. With some careful mathematical calculations, the amount of electrical energy transferred can be maximised.

Flying blue streamers of electrons flow off the coil and through the hot air searching for a conductive landing place. They heat the air and break it into a plasma of glowing ion filaments before dissipating into the air or surging into a nearby conductor.

A tremendous light show is generated, as well as a loud buzzing, crackling sound, which can be used to play music. The electrical theatrics are so stunning that Tesla was known to use his device to scare and mesmerise visitors to his lab.

Tesla might not have invented a source of unlimited power, which was one of his goals, but he did design a brilliant machine to demonstrate the sheer power and beauty of electricity.

The “Earth is a realm” quote is often wrongly attributed to Nikola Tesla in flat-Earth communities and incorrectly regarded as “evidence” that Tesla believed Earth is flat.

Someone wrote pseudoscientific drivel and added an actual quote by Nikola Tesla. Flat-Earthers wrongly assume both statements are by Tesla & it became a hoax claiming Tesla was a flat-Earther.

The quote by Tesla was taken from “The Problem of Increasing Human Energy,” in which Tesla mentioned the word “globe” 12×, “gravity” 4×, “planet” 10×. It is clear Tesla was not a flat-Earther.

The source of this problem is a Facebook post that quotes Tesla by a Facebook user named ‘Darrell Fox.’

“Earth is a realm, it is not a planet. It is not an object, therefore, it has no edge. Earth would be more easily defined as a system environment. Earth is also a machine, it is a Tesla coil. The sun and moon are powered wirelessly with the electromagnetic field (the Aether). This field also suspends the celestial spheres with electo-magnetic levitation. Electromag levitation disproves gravity because the only force you need to counter is the electromagnetic force, not gravity. Though free to think and act, we are held together, like the stars in the firmament, with ties inseparable.”

These quotes are widely circulated in the flat-Earth circles. The message got mixed up at some point, and they began to assume that the entire passage was from Tesla.

The only part that Tesla said is the last paragraph:

“Though free to think and act, we are held together like the stars in the firmament, with ties inseparable. These ties cannot be seen, but we can feel them, each of us is only part of a whole.”

Some unscrupulous flat-Earthers even ‘simplified’ the section, and then it got passed on as:

“The stars are attached to the firmament.”

The original quote by Tesla is from his article “The Problem of Increasing Human Energy with Special References to the Harnessing of the Sun’s Energy,” published by Century Magazine, June 1900.

It was only a figure of speech, emphasizing human togetherness in the energy problem. And obviously, it doesn’t refer to the shape of Earth or its motion.

Some Quotes from the Article

This metal, it would seem, has an origin entirely different from that of the rest of the globe.

…

It is a well-known fact that the interior portions of the globe are very hot, the temperature rising, as observations show, with the approach to the center at the rate of approximately 1 degree C. for every hundred feet of depth.

…

The difficulties of sinking shafts and placing boilers at depths of, say, twelve thousand feet, corresponding to an increase in temperature of about 120 degrees C., are not insuperable, and we could certainly avail ourselves in this way of the internal heat of the globe.

…

By realizing such a plan, we should be enabled to get at any point of the globe a continuous supply of energy, day and night.

…

I was confident, however, that with properly designed machinery signals could be transmitted to any point of the globe, no matter what the distance, without the necessity of using such intermediate stations.

…

The observation of this wonderful phenomenon impressed me strongly that communication at any distance could be easily effected by its means, provided that apparatus could be perfected capable of producing an electric or magnetic change of state, however small, in the terrestrial globe or environing medium.

…

That communication without wires to any point of the globe is practicable with such apparatus would need no demonstration, but through a discovery which I made I obtained absolute certitude.

…

For instance, by their use we may produce at will, from a sending-station, an electrical effect in any particular region of the globe; we may determine the relative position or course of a moving object, such as a vessel at sea, the distance traversed by the same, or its speed; or we may send over the earth a wave of electricity traveling at any rate we desire, from the pace of a turtle up to lightning speed.

…

My measurements and calculations have shown that it is perfectly practicable to produce on our globe, by the use of these principles, an electrical movement of such magnitude that, without the slightest doubt, its effect will be perceptible on some of our nearer planets, as Venus and Mars.

…

Its practical consummation would mean that energy would be available for the uses of man at any point of the globe, not in small amounts such as might be derived from the ambient medium by suitable machinery, but in quantities virtually unlimited, from waterfalls.

…

Men could settle down everywhere, fertilize and irrigate the soil with little effort, and convert barren deserts into gardens, and thus the entire globe could be transformed and made a fitter abode for mankind.

…

On the other hand if at any point of the globe energy can be obtained in limited quantities from the ambient medium by means of a self-acting heat-engine or otherwise, the conditions will remain the same as before.
