I disagree, there is a secret to the triode, a triode is the voltage version of a transistor NOT a diode. Grey did not show how he controlled the grid of the triode .... therefore it is secret in my book ... if you say it is not secret, then please share how he controlled the triode .. A triode when switched on has a bi-directional current path, not a one way path like a diode ..
EDIT: Actually I was wrong above, a triode only conducts cathode to anode when turned on. However, the grid is normally tied to the anode when used as a diode, this is not shown. .... and why did Gray just not put a diode symbol in there if the intention was a diode ... I still think the grid was controlled as a triode to get the pulse short enough .. and if the intention was to stop current reversal, then the grid would have to be controlled relative to the resonant frequency ,,
As far as the commutator is concerned, it was to control the sequence for pulsing the coils .. it is not necessary for proving this effect ..
