Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Unfortunately now, Stefan Hartmann is very ill and He needs our help
Stefan wanted that I have all these massive data to get it back online
even being as ill as Stefan is, he transferred all databases and folders

I have found few errors and I will delete video and post   one with corrections !!!!!

flyback driver without easy adjusting output frequency can be used only if we know exactly how to tune to resonance, but even Tesla used tunable circuits because it is almsot impossible to match all parameters without adjusting

If precise frequency control is important then use the TL494 with an H-Bridge output stage, like Meggerman has suggested

Another way would be to drive the two mosfet gates with a TL494 push-pull IC so that you can control the mark space ratio and hence the driving power to the primary winding.

Attached is a picture of the TL494 on a small bread board.
I also have built this permanently on a vero board with a range of caps that can be jumpered in/out for a range from 50Hz to about 900Khz. I will post a picture of this one later.
Red/blue on 17/18 are the two push pull outputs.
10K trimmer on 6-8 is duty
100K trimmer on 22-24 is freq.
0.1uF yellow cap on 7-9 is frequency range cap (swap out for a different range).
I think this was set to go down to about 60Hz but the cap could be changed to allow it to go lower/higher.

My next step is to strip the HT coil + ferrite yoke out of an old TV thats in the loft.

@Wesley, which is the better design to work with: deflection Yoke or Tube + ferrite?
