Richard Hull answers Richard Wall:

Absolutely!!!  The resonator can be sort of,... kinda,... maybe,...be 
viewed as a laser cavity.  The primary is the flash lamp. (energy input 
source).  The helix of wire is the tuned cavity.  The ground is the 100% 
reflective mirror.  The toroid end is the partially silvered output 
mirror/window.  A bigger toroid (heavy silvering) traps energy within the 
cavity longer increasing the relative rise of power, via multiple 
reflections, but reduces the output duty cycle.  Smaller toploads or no 
toroid (very light silvering) allows the system to function but the 
energy output is minimal but more continuous.  Energy is conserved , as 
always, but the output appears vastly different in the two cases.  The 
energy in the coil is blasted in and out of the ground at the resonant 
frequency.  100% of the cavity energy (energy actually circulating in the 
resonantor tank system) passes through this connection! 

Lousey grounds show up as a real loser...the once 100% silvered mirror 
(ground) is now only partially reflective and emitting or releasing some 
of the trapped cavity energy! 

 There is some loss, or energy differential between this point and the 
actual ouput point, (heat, skin losses, resistive losses, etc), but it is 
fairly minimal in a good system.  This is where the rubber meets the 
road!  I would say that a measure of the base energy would closely follow 
the actual output energy of the system. 

 From my measurements ( not calculations) made in the past on two coil 
systems, this is on the order of only 10-20% of the wall outlet supplied 
energy.

If you want to see nasty raw RF power,..  If you want to smoke 
instruments,... stick 'em in the base/ground circuit of a big system.
