	Wrong.  The energy is initially stored in the primary capacitor and is
transferred to the secondary during the time the gap is closed. 
Resonance in no way increases the amount of energy.

	Wrong.  The best one can achieve is 100% energy transfer, at which
condition the peak voltage at the secondary will equal the peak primary
voltage times the square root of the ratio of primary capacitance to
secondary capacitance.

	Energy is stored in the magnetic field of the coil, and at any instant
is equal to 1/2 Li^2, where L is the inductance and i is the current.

	The only difference is that the stored energy is is equal to
1/2 Cv^2, where C is the capacitance and v is the voltage.  The
oscillation of the secondary voltage represents a periodic exchange of
stored energy between the inductor and the capacitor.
