The true Tesla Coil
« on: December 15, 2012, 05:42:41 AM »
I was hoping to start a discussion on exploring Tesla's notion of the "extra coil" in his system aside from the primary and secondary. The most interesting diagram I have ever personally seen in regards to the true Tesla Coil is that of Eric Dollard's which approaches the subject entirely different than a conventional Tesla transformer, or even the systems I have been personally developing. It takes advantage of David Sereda's concept of a differential harmonic created between two different electromagnetic waves in between each coil set. This diagram can also include a spark gap in between the capacitor and the primary. I have reread Dollard's Condensed Intro to Tesla Transformers several times over, and several parts I've lost count. This piece of writing is like no other in the free energy movement. I would love to hear other people's persepctive and opinions on the subject.

I have been coming to this same conclusion...  That the sparks from a tesla coil are not from the power put in (not a transformer).  If you get into researching back EMF you find videos where putting power to a coil then stopping it creates a back emf voltage spike. I even saw a video where a guy used a switching circuit to pulse power to a coil and collect it.  Do some searching on Back EMF Thief.  It may make you rethink the Tesla Coil.
Then do some research on "electron avalanche and Townsend  Avalanche".

My conclusion in teslacoil is different. I believe that the real source of power of teslacoil is the earths magnetism. The primary coil vibrates the earths magnetic field and this what cause extra energy in the secondary. I made up with this conclusion when i notice there are similarities between teslacoil and magnacoaster. In inductor alone the power that put in is equal to the bemf. But when the magnet was added like in magnacoaster, the bemf become greater than the input. Same with teslacoil, the earth act as a magnet and this what cause an increase in power in the secondary.

My first time hearing of the magnacoaster. I'll research it and see if I can see your perspective. Sounds interesting. Makes me wonder how a small radiation source would effect the back EMF.

I did some researching and I found some answers for you.  Basically magnets will change the inductance and resistance of the coil. If you don't know this you will see voltage changes that can deceive you. From some info I found where a guy tested putting magnets at each end of a fly back coil. The resistance and the inductance drops with the magnets. http://www.overunityresearch.com/index.php?PHPSESSID=4fd888aa4bb4c00ac57e21426c98c12f&topic=173.0

It is my belief that ZPenergy comes from Dielectric absorption. You fill the coil with a charge and the atoms of the coil and
air around it swing to polarity like tiny bar magnets. When discharged, the atoms swing back to their original positions. Like pulling back a pendulum then releasing it. The energy comes from the swing back. The swing back could possibly be a realignment with earths weaker magnetic polarity. Ignore the first paragraph http://en.wikipedia.org/wiki/Dielectric_absorption

Hi,

Sorry to jump in, would like to draw attention to "resistance" in your text below which was meant to be impedance in the original text i.e. inductive reactance. The usage of the word "resistance" by the guy was a mistake, normally the word resistance refers to wire DC resistance,  see this Reply #13 and also Reply #16 on the same thread: http://www.overunityresearch.com/index.php?topic=173.msg1518#msg1518

So a permanent magnet can change the inductance of a coil wound onto a ferromagnetic core and this naturally involves the change in inductive reactance of course but the copper resistance of the coil does not change.

Thanks,  Gyula

Interesting comment Neo. Your Magnacoster thoughts remind me of a similar idea to from a regular poster named IST a few years ago on YT:

Hi Folks,

The Corum brothers have studied very thorougly the Tesla coil and some of their papers can be read freely on the net. See  here: http://www.tuks.nl/pdf/Reference_Material/Corum/  and if you read  paper "Tesla_Coils_and_the_Failure_of_Lumped-Element_Circuit_Theory"  then you find that the secondary coil is a quarter-wave resonant helical resonator, albeit it is a basically a single layer solenoid air core coil, positioned with its axis vertically and driven at its bottom.  Its voltage 'magnification' comes from the standing wave: any 1/4 wave long conductor or (elongated metal structure) has a voltage maximum at its end when excited either inductively or directly at its other end by a frequency which corresponds to the 1/4 times of the self-resonant frequency of this conductor (or metal structure, in this case this structure is a solenoid coil). 

Here is a series of a symposium video on the Tesla coil by James Corum:

Sorry Folks, here is the second half of the above sentence correctly:  any 1/4 wave long conductor or (elongated metal structure) has a voltage maximum at its end when excited either inductively or directly at its other end by the full wave frequency which corresponds to the self-resonant frequency of the full wave long conductor (or metal structure, in this case this structure is a solenoid coil).

Hi Greg:  Thought that you might like to know that Tesla's Wardenclyffe tower was simply
a very large impedance matching transformer, in between his radiant energy
Converter and the earth. Just like the one that is most likely on your house.

The 10,000,000,000 watts of free electricity was created in his lab by his
Radiant Energy Converter, which converted etheric currents into electric currents.
He then simply pumped this 10 billion watts of energy into the earth with his tower.
More Later,
Nik

I read a little peace of Teslas research paper.  He said that there is great power using a Globe within a Globe.  He reffered to the Earth and the core, and also the earth and the ionisphere and the energy that is produced.
Any thoughts on Teslas love of 3,6 and 9.  Maybe using the 3 turn primary with a 6 turn secondary.  Then use a 9 turn recieving coil.  Or is that just nothing?

The problem I have seen is that people do not understand Tesla, because they tend to either "look for the mystical", or place Tesla on a pedestal as somehow "unknowable". Tesla was brilliant concerning resonance, and understood inductance, reluctance, reactance,  and capacitance extremely well. He was also an ordinary human being such as you or I.


Tesla was a practical man, which I gathered quickly after reading his patents and research notes, as well as many of his lectures. His goal was not resonance for resonance sake. Every application of resonance in any situation had a very specific purpose. He designed his coils in numerous ways, for numerous purposes. Some might be wound for specifically high potential, and designed on the quarter wave principle for that purpose. Others might be wound specifically to test theories of self capacitance, self-inductance, reluctance, etc.


"Tesla Coil" as Tesla made them encompasses a great number of possible designs each for potentially different purposes.


The question then naturally must be asked. For what purpose do you wish to achieve? You then use Tesla's concepts to achieve the goal.


Want a coil which will resonate without a capacitor? All in the coil design, as you choose a design and wind for the proper self capacitance, with both the inductance, wire length, and capacitance designed for the desired frequency.


With enough thought in your design, you can use the properties of coils to simulate almost any basic electrical component of Tesla's day.


Just because you see a coil in Tesla's notes, pictures, or drawings..... don't automatically assume it is there as a conventional coil.  :o


That used to logically trip me up.

The surface of the earth is a conductor. So is the core, and so is the ionosphere. There is dielectric between each, and as such form two separate but connected capacitors. They can be used to either store, transmit, or provide energy. These capacitors are constantly being charged by the sun, so inherently hold a vast amount of energy, some of which we see exchanged with breakdown of the dielectric as lightning with it's temporary localized equalization of charges.


Telsa had a "thing" for resonance. 1/4, 1/2, 3/4, 1, multiples of 2, as well as 1/3, 2/3, 1, and multiples of three. The first were for harmonious resonance, the second set for destructive inharmonious resonance. Harmonious and inharmonious are often overlooked. They are not used in modern electronics or concepts of resonance. However, Tesla had a "thing" for any and all forms of resonance including physical, field, and electrical. "Waves" interested Tesla also, and it made no difference if it were pressure, sound, or radio.


Those numbers all have to do with wavelengths, harmonics, wave and field manipulation, and their respective uses and application.

This is a link to a scribe page.  It is a Book on Nikola Tesla and his Lecture before the New York Academy of Science, April 6th 1897.  It is about 167 pages long.  It is a very hard book to find, but it free to read directly from the web page.  It tells about how he makes some of his inventions.  Like the HairPin Circuit and the special Transformer that he made from a Pancake coil that has both the Primary and Seconadary in it and is made with 30 PSI and covered in Bees Wax.  If made right, it can produce 10 inch sparks from 12 watts.  It also can draw in Ambient Either Energy, that in the Dark can be seen.  It can only work right if made in a vacume, with no air present in the coil.  I would love to hear of everyone making one and gathering the Either energy that it draws in.

How should this coil be properly excited ?  To get what is written there.
From 50 volts 25kilovolts. That is, the square root of 250,000. ?
