Tesla Patent 512340 REDUX

[armagdn03]

An interesting patent to dissect indeed.

what is a capacitor, what is an inductor?
A simple answer to this question is, that all electrical systems are both. It just so happens that what we term capacitor and inductor are geometries that we have chosen to capitalize the properties of either capacitance or inductance. Because of this it should be noted that capacitors have inductance, and inductors have capacitance. Geometry is everything. Now that were done stating the obvious, consider the asymmetrical capacitor, (such as used in bifield brown experiments).
In the image below, the light red represents a positive charge with a low charge density (small charge per area). The next size down will be of opposite polarity and have a greater charge density. This can be continued down to a point where the charge density will be the greatest. This is the reason we want to keep sharp points off of tesla coils and such, because it leads to charge leakage. This applies directly to cylindrical (or in this case pancake) capacitors. Now think about what this means for the center of the coil.


Also consider the fact that this geometry does not create a capacitor in the traditional sense as the opposed conductive surfaces are electrically connected. This means that when a discharge is introduced into the coil, it will be absorbed primarily by the capacitive nature of the coil rather than the inductive property. This means that the natural resonant point of the coil will fall at a lower frequency since the capacitance and inductance are closer. This coil will ring because of this electrical connection, since the collapse of the electric stress field will enter the inductive property of the coil.  In and of itself, it is a mini LC circuit much the same way any coil is.

And one more to think about. Due to the nature of the coil the magnetic (inductive) properties are minimized to their smallest, and the electrical field components are voided, save the stray field at the periphery. so if we are left without dielectric, and magnetic fields (or at least they are kept to a very minimum) where are we? What is the perpose?

Tesla:

Capacity secured in this particular way possesses an additional advantage in that it is evenly distributed, a consideration of the greatest importance in many cases, and the results, both as to efficiency and economy, are the more readily and easily obtained as the size of the coils, the potential difference or frequency of the currents are increased.

What does Tesla mean by this statement?

[armagdn03]

Again it is about geometry, a parallel plate capacitor may not be perfectly parallel, meaning the charge distribution may not be equal, the  more evenly distributed it is the less of a chance you have of dielectric breakdown. Also again, take into consideration that a wire, is round, while plates have edges, and It was just pointed out that the sharp edge builds up charge density towards the point leading to corona leaks, the tubular wire, will have much less of this problem, and will contain the charge better.

[Grumpy]

Not from the view of a capacitor, or charged plates (which is incorrect anyway) - look at this coil from the view of an impulse.

I enclosed a picture of what i was thinking about, consider Fig 1 a Tesla coil unwound and flatened, if the frequency is low the compressive tension (+) will encompass the whole coil both wires as the wavelength could be many kilometers long, as will the (-). But at high frequency a full wavelength could correspond to the length of the coil(conductors A,B).
In fig 2 we can see Teslas coil in another orientation, here it is more obvious that one conductor A is under a compressive force and B is under a expansive force, opposite conditions between parallel conductors or a maximum potential difference. Now consider an ordinary capacitor, two plates in close relation, there is almost no possibility that this effect could manifest itself as the wavelength is too large, that is we could not concievably produce frequencies high enough to produce this effect.
There is also the fact Teslas coil is reducing in diameter as we approach the center of the coil, the question is how would the conductor percieve this? Also at any point "in" the coil the conductor A has conductor B on "both" sides of it, this conductor B on one side of A is at a different potential than conductor B on the other side of A because the diameter is always reducing, thus potential changes at any given point in a wavelength. As such I think this potential difference as a capacitive effect could possibly be in motion as the potential difference is applying a force both sideways and let's say forward, and a potential difference initiates current flow. Needless to say this is no ordinary coil and nothing like the bifiliar coils people have been winding.
