From HyIQ's video showing this effect:   ""On rare occasions, Sweet saw this effect, called self-oscillation, occur in electric transformers"

and

"Sweet was also a transformer designer and expert, and he remarked that he had also observed specialized self-oscillation in certain transformers. "

I show the importance of knowing and understanding the A Vector Potential and how simple it is to create a self assisted oscillation. This set of shorted Self Assisted Oscillating Coils. This can be improved hugely and is possible to be made to self run with this technology. Nikola Tesla, Floyd Sweet, Lester Hendershot, Edd Leedskalnin and Daniel McFarland Cook all knew about this technology. They all used it in various ways to improve their devices...."

xenophed - thanks a lot for the details. That new diagram makes sense. Have to improvise on the wire, copper became really expensive.
So, I'm AFK for some tests...

It is "capacitive flame". It is tethered to ether itself, but still reqire power to glow. One wire glow is shown on neon lamp in upper post. I decided to use blitz lamp from disposable camera, so effect cann be beter seen trough clear glass.

Other end is not connected and no glow(flame) there.

In stumbling around some other ideas today I came across this info which Floyd "Sparky" Sweet (well known for his Vacuum Triode Amplifier) was studying and was likely a part of his fascinating creation.  The statement ""An alternate explanation for the current gain in the UDT is to consider each secondary winding as acting as the primary winding for the other secondary winding when an output current is drawn because the two secondary windings generate geometrically opposing fields."  The UDT as describe here: http://www.hyiq.org/Research/Details?Name=A%20Free-Energy%20Device  provides more power out than is consumed at input.   Perhaps something similar is happening here with xenophed's coil and circuit.   
Also of interest is that today the news update from HyIQ is he believes he has cracked the riddle of Floyd Sweet's VTA.   See www.hyiq.org

Video below demonstrating the device shows different to the statement I made bold text above.

Input is 1.2 Amperes at 12.6 volts = 15.12 Watts input, output = maybe 2 watts (not fully lit 2 Watt bulb). Which is about 13% efficient. How does anyone come to the conclusion it is even efficient not to mention say it gives more out than in ?  UDT device video test from 2011. https://www.youtube.com/watch?v=iJsVSMQqCOM

Please explain.

For the 15 Watts input it should be able to light up at least 4 of those globes to full brightness (3 Watt each x 4) with 12 Watts output, but it cannot even light up one to full brightness less than 3 Watts, looks like less than 3 Watts.

Farmhand,  Chris (the person that has the hyiq.org web site) seems like a very sharp guy to me.   He states on his web page : " I think it is important to note that this type of device is more than real, I have shown that it can work. Click Here to see my video. "
Floyd Sweet describes this same action as is described above: "If the directions of the two signals are such that opposite H-fields cancel and E-fields add, an apparently steady E-field will be created" "I watched his video too but I am not sure how to interpret it - I was taking his word for it.    So who am I to believe?   I'll watch it again later or maybe ask him for an explanation.   From what I've seen the past couple years Chris does very good and thorough research.   I think he will be better to ask for an explanation.   
I took another quick look at the video.   Firstly we don't know the efficiency of the big amplifier.  It looks like a car audio amp so if we are lucky maybe 50% efficient.    Secondly it does not seem he is trying to show efficiency whatsoever in that video but rather is simply demonstrating that the shorted coil setup causes a self oscillation which results in the light getting brighter.    It appears he is not showing the UDT but rather just one basic concept involved in how the UDT works.
