No, the high rise time and fall time is for the establishment and disestablishment of the arc. Think of a Tesla coil Spark Gap with a grid around it that is charged positively and the arc negatively. That of course would be near identical to an Edwin Gray conversion tube and possibly a r esistor would be required to keep the arc negative. > > > The screen will pull negative particles out of the spark-plasma and > accelerate them out into the air. No, the screen is formed into a cylinder so the Faraday effect ensure it will have little effect. > Will I feel a stinging sensation on my > face? If Tesla is replicatible perhaps.

But Tesla didn't find them entirely stopped by metal. Also how can microwaves charge something with a static charge? It would be a stretch to propose that microwaves are the cause of any and simply impossible to be the cause of most of the evidence.
