Sure, if you keep pumping AC current into a parallel tank, it will store energy. DC voltage into an inductor will store energy too. But we don't want to store energy in the transmitter coil, we want to charge a car battery.
At K=0.1, most of the transmitted mag field is going into places that are not the receive coil. Your sim has over a 10:1 ratio of coil currents, which will be over 100:1 ratio of copper losses.
In your sim, the voltage across the transmit coil settles to about
2.5KV p-p. The coil dosen't know where that voltage came from.Your load gets about 500 watts, 6.7 amps RMS. The capacitor current is
96 amps RMS and the drive into the transmit coil is 90 KVA.Resonating is just a way of impedance matching sine waves. Given some driver technology and some coil geometry, it might make sense to invest in some giant film caps, series or parallel, and maybe cooling for them. But resonating is not magic, except that it seems to be for raising money. If there is practical amounts of power transfer, Q must be low. That's one definition of Q.
