ok   here is some items that can be had for this experiment.  A 2mh coil made of 16awg wire that came from mid 80s passive sub cross-over supplies, and I have 16 560nf 1kv caps that I can arrange up to 8kv at 560nf or a few other values to work in the range of the circuit I posted last.   
The key is to be able to discharge the cap into the coil with an electronic cutoff when the cap reaches 0v, or the cap will start charging the other direction and if released at other than 0v the oscillation voltage will suffer.
I have some ideas i will try electronically. Tesla used motorized rotational switching that was tuned for what he needed and could produce even a rectifying effect from it.

I was just investigating some materials on microwave oven circuitry and operation. I saved a transformer, a diode, and a cap from a scrapped unit and just wondered exactly what goes on in there. And also what can I do with these parts and what they can do for me. 
I found a very interesting description of the transformers they use and why there is a gap in the center core.

Here is the description  and I found it here   http://repairfaq.ece.drexel.edu/sam/micfaq.htm#micwdmleak

High voltage transformer
(From: John De Armond.)

The transformer goes by several names, depending on where you are. Variable reluctance, leakage flux, stray flux, etc. It is exactly the same construction and operating principle as a neon transformer, some kinds of HID light ballasts and some series streetlight constant current transformers.

The core is an almost standard "E" core (or "H" core if you prefer) with one exception. The center leg has an air gap. The windings are on the end legs of the "E" instead of the center leg.

There are two magnetic paths around the core for the field set up by the primary to travel. Around the periphery and across the secondary and around the center leg and across the air gap. The field that travels along the center leg does not cross the secondary and induces no voltage.

With no load applied, the bulk of the field travels the peripheral, very much lower reluctance solid iron path, inducing full secondary voltage proportional to the turns ratio. As current flows in the secondary, counter-MMF raises the reluctance of the peripheral path so that some of the flux travels through the center leg. With less flux traveling around the periphery and cutting across the secondary, the secondary voltage drops as the current remains about the same. At the limit, if the secondary is shorted, the peripheral path has so much reluctance that most of the flux travels the center leg and across the air gap. The same current as before flows through the secondary but at zero volts.

When the dimensions of the core and gap are set up correctly, the transformer behaves as an almost perfect constant current device. That is, the secondary voltage varies as necessary to keep the same current flowing through a varying load. Just what the doctor ordered to keep the magnetron happy.

The secondary current can be increased by opening up the air gap. This raises the reluctance of that path and forces more field through the secondary leg. Closing the gap has the opposite effect.

The center leg is often called the magnetic shunt and frequently it is a separate piece of laminated iron stuck between the coils and TIG welded in place. It is a common trick for Tesla Coilers to open up a neon transformer and either knock out the shunt entirely or grind it down to open the air gap. This modification causes the transformer to output much more current than it is designed for - for a little while, at least :-) The same thing works with microwave oven transformers (MOT).

This design in a microwave oven is a vital part of keeping the magnetron anode current within spec. The magnetron is electrically a diode. A diode that isn't emission-limited would draw destructive current if not externally limited. With this design, the filament can be heated good and hot for long life and not have the tube run away. The design also is vital for protecting the magnetron from potentially damaging conditions such as operating the oven empty, arcing, etc.

It's popular to use several MOTs to build an arc welder. This works quite well specifically because these transformers are constant-current devices - exactly the characteristic stick welding needs. If they were conventional transformers, the first time the rod touched the work and shorted the secondary, fault current would flow and the breaker would trip or blue smoke would leak out.

Along similar lines, one can cut off the high voltage secondary and replace it with a suitable number of turns of heavy wire, connect a bridge rectifier and have a nice constant current battery charger. Select the turns carefully and it'll do the bulk/absorption stages of the smart 3 stage charging algorithm.

I was playing with the circuit sim today after reading your posts here.  It seems not-too-difficult to get seeming OU configurations of RLC circuits using it.  Is this maybe just a flaw with the sim?

This one appears to take 1W in for 5W out: (attached txt file for the falstad circuit sim)

Also Void and All

I had shown a circuit code above with the comparison of in and out power. I chose the 2ohm resistors in order to try and show equal loads for power measurements to be clear.  It is possible that if I used .2ohm resistors, that the power consumed by the resistor alone, may not be the total power in the lrc as a whole.   Point being, the 2ohm resistors are most likely the weak link.   Otherwise, we need to measure all components to see what the total power dissipated on each side, in/out, really is as a whole.   If the resistor is very low, its power dissipation will be very low due to low voltage across it, so now wee would need to see the power dissipated into the inductor to get a true circuit potential.

If we have 2 100 w bulbs in series, on 110v, then each would get 25w and the total would be 50w dissipated.
If we have a 500w bulb in series with a 100w bulb, the 500w may not even light up, but the 100w may be near to full power.  But just the measurement of the 100w bulb will not give the total power consumed, so what ever the 500w bulb is consuming, should be added to the 100w as a whole.   But the 100w should give a pretty good indication of high majority of power consumed as the 500w filament will be at much lower ohms than the 100w when full current is running and the 100w is hot and high.

Hey Void
The diode is a ruff way of doing it, It does the cutoff near zero, but the switch still needs to be opened on or near that time also.
Im thinking what we need is a comparator circuit that measures the caps voltage discharge and use it for a trigger to cut the switch(mosfet, etc)  It all has to be quick. But with what we have to work with today, I think we can gitter done.

The basics of the so called amplification is here. I say so called due to it is the end result, but not conventional for most.  Now the switching needs work. And now that I get the feel of the lrc, how it works, and the required switching, The switching does not seem that hard to do after all.

Some say the mosfets wont do what Teslas did exactly, but it will work.  Lets say that a mos transistor doesnt have quite the on resistance or timing we are looking for, so what, if the input suffers a tiny bit, the output will suffer a tiny bit, but the power ratio should be similar. And the sim is showing we can get some amplification at lower voltages and freq also, and thats what I am going for.

Cold electricity is cool, lol, but I cannot say that is what we have here. Yet anyway.  Just inductors with inertial effects and caps that tune the bounce in the circuit.  Basics.

As I come up with the switching circuits I will upload the codes.   Ill send the diode on the cap tonight to demonstrate that its function is desirable here, and then work on the How To Switch  it circuit.

Thanks for giving it a shot, I could use a another good mind to help me out. =]

Mosfets are so made they won't work of smoke immediately in case of any energy gain

Maybe we just werent looking close enough.   I took a screenshot of my desktop, zoomed in on the input and output power traces and used photoshop to stack them.  I also decreased the time step so we could get a close look at the waveform of the output.

It looks like while I'm getting 2.5KW on output, with 1.25KW on input, the output is in the form of a damped oscillation(I think that's the right word), so half of the apparent power isnt power.  Which incidentally also points that if you discharge the cap at optimal (0 volts) you get roughly twice the power out.  If I'm interpreting that correctly, still new to the solid state area

Ya, I did the exact same thing - I was elated to see the simulated results, and yet something was nagging in the back of my mind regarding the fact that the output was a solid color...  More than resolution of your desktop, make sure you change the timestep of the scope in the circuit sim to see the actual output at a resolution you can interpret - its under Options -> Other Options -> Time Step Size.  I just reduced it by a power of 10 and was able to see the damped oscillation.

I think I've been interested in OU research for almost a year now.  I'm becoming accustomed to disappointment!  But it's not a bad thing, I don't believe.  While the knowledge I am gaining is showing me that most of what is presented that looks promising is either due to measurement errors, poor research or even disinformation distractions, it is also securing a tenuous opinion that we have taken a wrong step (or several) over the last century with regard to our understanding of physics.  Perhaps even misled, which sometimes seems far more likely.  But if we can recognize this misstep, we can correct it, and I am more convinced today than I was initially that there is an answer waiting to be discovered.
