Ok, but don't confuse the Tesla effect with transformer effects.
Either one can raise voltage quite high, but the mechanism is very
different. 

A transformer does its thing purely by magnetic coupling and does not
store energy from one cycle to another. 

A Tesla coil, by comparison, stores energy by means of the "flywheel
effect" of a parallel resonant tank and actually adds more energy with
each RF cycle that is pumped into it, something a transformer can not
do. The amount of energy buildup is limited by the Q of the circuit
and in many cases, by corona if the voltage gets really high. 

A true Tesla coil, as built by some experimenters, contains both a
parallel resonant circuit and a transformer and uses both phenomena to
achieve some truly spectacular results. I visited the Tesla museum in
Colorado a few years ago and they demonstrated a million volt Tesla
coil - truly awesome.
