Very interesting.
Old Tesla.

Nice,2nd pdf is too similar to EMjunkie's partnered output coil proof-of-concept experiment.

Most imprtant is 1/4 wave electrical distance from the source to the load.

Welcome. I i knew from the first moment you mentioned vector sum you are
referring to phase angles, but why even waste time on such well assumed basics.

Ofc capacitive current leads voltage by 90° and inductive current lags voltage by 90°, clearly, from outside perspective they cancel out and only ohmic loss current remains. I been saying this for years here and it's been known forever.

I addressed this detail already when i said how loading the resonant tank destroys resonance and brings voltage and current in phase.

Video you linked is ideal parallel RLC which is the exact opposite of real parallel RLC
Q factor wise. In ideal parallel RLC resistor is not in series with an inductor (as in real RLC) but in parallel, thus Q factor is proportional to resistance while in real parallel RLC Q is inversely proportional to resistance, just like for series RLC.

What matters is that, contrary to conventional "wisdom", one can build up reactive power in parallel RLC and this reactive power if done correctly can become a sink
for ambient.


As for 1/4 wavelength, that is all nice and sweet but ultimatelly we see it's totally not needed. Most of OU devices work at lower frequencies, few dozen KHz max, 1/4 for that would be many km/miles, For example for 50Hz it is 1,500 km, so we see it does not matter at all.

Here is another example what's possible with resonant trans....

He is drawing about 17W from the wall and powers few hundred watt
worth of lamps almost completely from earth.

Already tiny amp draw from the wall goes even lower when he turns on the lights.

Tesla coil works in kHZ range. It is a slow wave structure. Any loaded helical transmission line have velocity inhibiting properties. You get 1/4 wavelength with reasonable size.
