This technology reminds me of a sonic cavitation device called an eroder that is used to machine extremely hard materials. The spark in the liquid causes transfer of the energy by cavitation bubbles.

This machine dissagregates minerals perfectly at their boundarys, separating the rock into its largest perfect individual components with no chipping or fracturing. The liquid is just tap water.
This is much better than crushing to extract precious minerals as that process also breaks many of the larger grains.
This machine does it in a few nanoseconds... just a single pulse needed.

I thought it would have to be water, surely if the vessel were filled with kerosene it would explode or catch fire?
The high voltage research group at my university built a rock drill powered by three Marx generators, fired repetitively one after the other to create a rotating plasma. This seems like a more marketable idea though, seeing as it recovers valuable material from rocks.

Spark eroders of the type Radiotech was (presumably) referring to above generally use kerosene/paraffin as the dielectric, although I've also successfully used glycerine as well. Antifreeze (ethylene glycol) should work as well.
The discharge is below the surface, so no oxygen is available for combustion to take place. The flashpoint of kerosene is also quite high, but I've never discharged 200kV into it.
Presumably this setup is powerful enough to reduce H2O to hydrogen and oxygen, which, well....BOOM!
(The colour of the liquid in the chamber looks similar to kerosene, that's why I asked, but this is presumably caused by by-products from the process.)
