how can one make a multi spark spark gap (get more than one spark)

[robowaffe]

Ive got this idea, to conduct through a dielectric by literally sparking through it,  the problem is u only get one spark,

but if i could get a lot of sparks (like a plane of them) and spark them all through at once,  then i can have conduction through a dielectric!  (like oil for example.)

So anyone got any ideas for a multi-spark system,  no stupid suggestions, and no stupid people.
