That would be peak output power vs average input power. While moderately 
impressive at an  implied duty factor of about 1/600, I think that the run 
of the mill quarter shrinker is probably more impressive (because the rep 
rate is lower)...

60 seconds to charge a 10 kJ bank is only 170W.  Discharge current could be 
on the order of 20 kA at 20kV, for 400 MW peak power.

As a practical matter, many, many radars run at 0.1% duty cycles and 
probably have a 500:1 peak RF power to average input power ratio, at 
kilowatt kinds of average power levels.

No free energy anywhere..
