  Roughly speaking a VTTC uses a vacuum tube to replace the
spark gap. The tube is put into conduction long enough to
"ring up" the secondary, then cut off. The envelope is
approximately flat instead of exponential as in a SG coil
hence the "CW as opposed to impulse" explanation. That's
kinda raw; use Google to find more.

  As for Wardenclyffe rumors, I've still never seen a clear
explanation of how the "particle stream" was supposed to get
out of the alleged vacuum.
