Not so!!!!!!!!!!!!!!!!!!!!!!!!  It seems that the whole idea of a Tesla
coil(resonance) is being overlooked in this discussion. The above equation is
valid if, one time,  you take all the energy from one capacitor and transfer
it to another cap . In a resonant system you are taking oscillations or pulses
from one system (Tesla primary) and adding them up in a second system (Tesla
secondary -- an LC energy storage reservoir).

The equation  Vs = Vp sqrt(Cp/Cs)  should be Vs = Vp sqrt(NCp/Cs) where N is
the number of cycles or pulses transferred from the primary (if at 100%
efficiency).

 A bigger torroid gives a bigger spark because it allows the voltage to rise
to a higher value before "breakout"(allowing N to be larger). If 100%
efficiency could be reached, a giant torroid would allow the primary to pump
up the secondary LC system for a week with one spectacular spark at "breakout"
from the torroid (and a very large voltage).
