then what`s the point in using series rotary at all - only in reducing
heating of each flying electrode? but this is a wrong way - you can
achieve the same result just by increasing the number of electrodes, so
you don`t introduce additional air gap which is bad thing (coz this
means additional losses).

series rotary doesn`t decrease the dwell time, right?

it`s written here:
http://www.lod.org/Projects/electrum/construction/pages/rtarygap.html

"with 8 gaps in series, the effective opening speed of the gap system
is mach 3.2"

you want to say, that this gap system is nonsense and just waste of
materials and power, and it can be done in _much_ smaller volume with
absolutely same performance, coz "opening speed" have no significance
at all?
