I think this is pretty interesting, I can see the disruptive and CW camps
kind of converging nowadays. If Jimmy Hynes ever gets his DRSSTC to work
then the confusion will be complete. As far as I understand it, the DRSSTC
is a kind of ultra-staccato SSTC with a resonant primary that builds up
hundreds of amps. It operates in short bursts of ~100uS and if you ever
tried to run it CW it would vaporise.
