Hi Sven,
"If it were just a mere sloshing of energy, voltage and current would not rise so much, but would have to stay at the same level as the input energy."
The voltage and current must increase when energy is increased. The energy can be directly calculated from knowing the LC-tank size and the peak voltage or peak current.
"Actually, the flyback in an induction is the boosting component. If there were no stored magnetic field energy, the energy would not increase in a resonant circuit even if it is blind."
Again knowing the stored energy of the magnetic field (i.e. calculated from the inductance and the current) is what determines the peak of the flyback voltage depending on what impedance the coil looks into. A high impedance flyback load must give a high flyback voltage peak as the current must and will stay continuous at the change in impedance by opening the circuit. The voltage to drive the same current at increased impedance makes the voltage step up at the rate of impedance changing. E.g. doubling the impedance requires doubling the flyback voltage to drive the same current through it. Thus the voltage is doubled but the time it lasts is halved.

Hi Ole,
yes, the energy spills back and forth like a wave. A wave power station is also there because the waves work through the up and down waves.
I think we divert some of the reactive power to let them do some work and then bring them back so the main LC does not notice what's missing.

Really hard to grasp this topic.
Maybe I should try the resonance experiment with my 3 spotlights, now I have 1200W as a light bulb in 3 lamps, if they shine bright with resonance energy that would be a confirmation of the energy, of course, only if the energy in the input source does not rise sharply.
