Those Tesla patents are one of such. They implemented what Tesla saw in childhood - snowball effect.
They are EXACT implementation of pendulum with special method of working.Pendulum which is powered by feeble impulses in phase AND additionally on each cycle it GROWS like snowball. Like a child on swing who eats hamburgers he he. Imagine that !

See ? Nature is our best teacher. Swing,snowball, also whip. Who can tell me what would be the implementation of whip in electric circuit ?

You just gave explanation how resonant effect works in RLC circuit. Just Tesla made it open RLC and added one-wire receivers.  Tesla made Tesla Coil like generator of reactive power and in receiver he just coverted it (picked up longitudinaly or transversaly) in any desirable form.

Delboy says that it is my transformers that are a problem. Im working on a couple air core designs that I want to give a go. we will see.  =]
In this circuit, I dont see that resonance is a tuned thing. Think about it, a gas engine will be changing rpm, thus the speed of the timing will change also. That is why I felt strongly about this. Now if we were able to store the output, can that be converted to a viable power that can run things or even recharge its own battery? Thats the way I see it.

For patent 609250 as electrical igniter for gas engines it doesn't have to be resonance to give spark on output. The point is that it will not draw huge current from source and you will stil have HV on output.
But I was not talking about making igniter, but TeslaCoil. Princips are same, just in Tesla Coil you have to regulate to achive resonant effect for max output. And YES, problem will be in both cases if your output transformer is one with core, because you will have large primary inductanse and oscillations will be slow (low volts/meter). Primary is only few turns of thicker copper wire or copper tube!
You want high inductanse with laminated core (for example 0,5H) only on input to prevent large current from source!
You must understand why is somewhere needed large inductanse and why is somewhere needed small inductanse!

I was searching for self induction coils and I came across a Nikola Tesla lecture book which had diagrams resembling the igniter type and also a double tank circuit so I thought of posting the link and one of the diagrams in the hopes someone might get inspired by it....

It's patent No. 577670. You can get Tesla patents on
www.pat2pdf.org   just enter number of patent without free spaces
This patent is improvement for production of HV/HF because with one condenser there is period of rest, when receivers are cut off for supply for a half period of switching period.
As Tesla says in this patent "high frequency may be produced thereby continuosly or without period or rest"

This is the patent which Scott McKie replicated (PODMOD device link I posted).

hey, all.

Actually what that book is refering to mr Goat, is Tesla's late patent of the "inductunce charging a cap" with consequent resonant action patent series (no. 577,670)

I have devised one traditional spark-gap Tesla coil lately, (check energetic forum http://www.energeticforum.com/renewable-energy/5186-patent-462-418-method-apparatus-electrical-conversion-distribution.html for report) and contrast it to my Solid State one (Kacher).

Ordinary Tesla coils of 100 or 120 breaks per sec does NOt have smooth resonance. Actually, it can be seen that with an o-scope. I exlain, upon every primary break, that happens in a small time period comparing with its charging time from the source, we have tremendous power "in an inconceivable small time, initiating results of huge power" or very very long sparks, yet the Secondary is inactive most of the time of vibrating at minute amplitube soon after each "bang".

In other words, it operates more or less as a tuned (for ringing) flyback transfomer. If you take into account the fact that the traditional spark-gap primary, DOES not guarentee every time will fire upon the same time interval hence cannot be absolute synergy bewteen every break..

This causes slight mis-phasing and true resonance cannot be achieved. Of course, rotary spark-gaps of constant speed solve at large this problem. After all, the very core of the those patents is a rotary switch of very fixed frequency. (that this is the core concept IMO of those Telsa patents series Tesla 568,178-568,180, 577,670)

So, by using a constant frequency switch and inductunce for charging a high voltage cap from low voltage, he could obtain smooth resonance and facilitate ease for HF HV currents making in a compact and simple apparatus to be used in a table.
Especially the  577,670 patent with the primary of two caps alternatively charging/discharging accomplishes this purpose attains Smooth resonance.

EDIT

I am curious, to see how the 577,670 arrangement as the picture of Goat has posted with the two secondaries is made and what its benefit. or in other words how a primary can oscillate two secondaries and yet being distinct form one to another?
