The Single-Coil Tesla Coil idea

[Magnethos]

Hi guys, in the following days I am going to experiment with a single coil Tesla coil idea I had some time ago.
As we know, an ordinary Tesla coil produces high voltage and a high frequency oscillations. In an ordinary schematic, we need the primary coil and a secondary (output) coil.


Well, after reading some information on the net, I came with an interesting and I think possible, idea: the Wattless Single-Coil Tesla coil.


The idea is to feed directly the secondary Tesla coil using high voltage, high frequency energy using single wire coming from a HV-HF transformer.


Here we have a visual representation of the differences between ordinary and single-coil, Tesla coil: [size=78%]http://imagizer.imageshack.com/img924/8918/FJiqxE.png[/size]


So, if we use a signal generator and we feed a step-up high voltage transformer with high frequency sine wave energy, then we will have high voltage and high frequency in the output of the transformer. As we know, we can use only one wire from that output, in a similar fashion as in an ignition coil [size=78%]http://imagizer.imageshack.com/img922/1760/oIPguQ.png[/size]


If only one wire is used, we don't close the circuit so the transformer will act as a transformer with no connected load. So, in theory, there would be only reactive power in the input of the transformer and displacement current in the output of the transformer. Placing a secondary (in this case is primary) Tesla coil in the output of the transformer, will serve as an antenna to move the free electrons in the air.


Then, some different circuits can be used to extract useful energy from the energy that the antenna generates without, in theory, affecting the power factor of the input of the transformer.

The advantage of a Tesla coil is to raise a voltage by resonance, i. e. a process that initially takes the energy of the source step by step, sums it and stores it in a form oscillating between the current/magnetic field of the coil and the voltage/electric field of the capacitor. Then the system is maintained by the energy supply from the source, which compensates for the losses.
If you produce a high voltage in another way, you no longer need a Tesla coil or you complicate a simpler solution.

The "one wire" transmission is an illusion. The circuit is always closed by capacitive coupling and the current flowing in the "one wire" still obeys the same laws as an ordinary current. Energy is consumed at the source when you feed a load at the end of a single wire, I checked this myself even if it was obvious.

Displacement currents have nothing to do with electrons in the air, which is an ionized path. A displacement current also occurs in a vacuum.

If you really want a single Tesla coil, simply feed it to an intermediate point in the winding, such as an autotransformer, not far from the cold point, preferably with that part of the coil wound with a thicker wire because more current flows there.

If there was more energy in a Tesla coil than we put into it in any way, it would have been noticed long ago.
Sorry for that, but I'm afraid that your idea is not "wattless" but "wattwith" as all other so-called "ideas" about Tesla coils, perpetually recycled about the manner but not in substance.

Technically this is not entirely true, we could ground one end of the Tesla coil then attach a parallel capacitor and a series rectifier to the capacitor and it would receive radio signals just like a crystal radio. Now if the primary was tuned to a nearby radio station and the output was regenerative then it could put out more energy that put in if the efficiency was high enough. It's never what we know that hinders us it's what we couldn't have imagined.

Real science is not some blind dogma or cult and we are collectively learning millions of new things each and every day. Now if everything is known or it should have been noticed long ago then why... are we still learning so many new things?. It would seem to be a contradiction and defy all logic and reason.

The fact is there will always be intelligent people who will question everything and they will always be learning new things. It's the people who stopped questioning everything and stopped learning we need to be wary of because they have no future and choose to live in the past.

It doesn't make any sense. The energy we receive from a radio transmitter is part of the energy that feeds the transmitter and is then radiated. If there was no receiver for the radiated waves, the wave energy is lost as well as the energy that supplies the transmitter.
If your receiver is near the transmitter antenna, i. e. in an area called the "near field" (at a distance of the order of wavelength), then there is a coupling between the transmitter and receiver, regardless of the type of coupling, an LC circuit or any type of antenna. This means that the transmitter "feels" the receiver as an energy source at the primary of a transformer "feels" the secondary when a current is drawn from the secondary.
If you put two receivers close to the transmitter, they influence each other and share the transmitter energy, each receiving half the power when only one can recover near all the power of the transmitter if the coupling is well designed.
Thousands of radio operators since the beginning of the 20th century have experimented in this field, I am one of them, and also professionals. If we could extract energy from such childish ideas, free energy would be a common product of the electronics industry for decades!
