why can't a tesla coil be torroidal - for a small coil this could be wound on
a heavily insulated bobbin - it the most efficient way of coupling all the
flux from one coil to another.... maybe a flyback transformer type
arrangement like I see for the transistorized tesla coils can be scaled up to
500 w to 1 or 2 KW???
If an unloaded Q of <100 would suffice, then it seems that the
space-wound geometry with a small toroid would be the best approach,
in order to achieve a lower L/C at the lowest cost. Why add extra turns
to the sec, if doing so only forces the addition of a larger toroid to
compensate? The extra turns do not add extra voltage.
