Hello, I have been curious about a few things with a tesla coil.  
     First:  I have read some of tesla's patents and articles.  It seems 
Tesla talks of a TC running in the MHZ to 100MHZ ranges, has anyone done 
this?  Is it possible?
     Second:  It seems that tesla often used DC for the input to his TC's, 
and the rotated a "contactor" to determine input frequency.  How does raising 
or lowering the input frequency from 60 hz change the resonant frequency?  
Like with 1 Khz input or so?
     Finally: on the rotational spark gap, can you run multiple disks off the 
same drive shaft and put the tunsten terminals an X degrees out of phase with 
the next disk?  If each disk were wired the same, you could possibly achieve 
higher switches or sparks per revolution of the motor without increasing 
possible arcing, right?  Just curious.
