Shorting coil gives back more power

[Goat]

Would add a note about Tesla bifilar vs regular coils. While for drive coil one certainly wants low inductance and fast response and Tesla bifilars are in business, it is a bit mixed bag with shorting coil.

If you look from one side - when shorting there must be rapid current buildup - low inductance helps with that.
If you look from other side - when unshorting there must be large backspike - high inductance helps with that.

So it is very complex problem with multiple variables. I guess some smart dude must do a dynamic über-coil that morphes between low and high inductances inside on shorting cycle

For example in the military they get kicks out of charging up big inductance and then get EMP by shorting individual turns step by step.

Thank you for your input on the Tesla bifilar vs regular coils and the Flux compression generator.

I have been thinking on various Tesla variations of his "Pancake bifilar coils" and the variations of such coils as opposed to normal solenoid coils and also any other coils like stepped or others, I can't help to think that we have barely started to explore in a scientific way what every coil once charged and shorted in the appropriate manner might return to load and source, is there really any extra energy in the right circuit?

As far as the Flux compression generator I can't help to think that there must be energy coming from the high explosive coming into the picture.  The only way to know for sure would be to exclude the high explosive and arrange a mechanical or electronic method to short the coil windings in succession as the high explosive would do.

Could we use diodes or other transistor devices, FET/Zener or other in between coil windings to start a shorting the coil windings in an avalanche?

If you look at shorting a coil such as the secondary of Tesla's patent 609, 250 (see below) for instance, how could one operate the charge/discharge while driving it into a load and feeding back to the source instead of  a single discharge into a spark, can we convert it back to the source with energy to spare?

Hope this makes sense...if not please ignore this post, just thinking ;P

Edit:  I also just thought of something that might be of interest as far as shorting coils.  What about Edward Leedskalnin's Permanent Magnet Holder (PMH), isn't that the same principle of the charge/(short) hold/discharge cycle as what we're discussing here?

Hehe, looks like you catch the drift

In relation to the above, how about this?
