actually churns plasma external pool... centrical shunt or inner plasma pool is constant.... the non-energized plasma plate... although both are hydrogen charged for polarity push... the outer is activated emitting quanta... early designs had separate chambers.... TOS would have outer chamber inner core... with a tubing that initiated the staged polarity through a "wiper" activating polarity push. Your warp field was emitted through flux... not quanta being resonated in great magnitude. Although quanta is generated and the coloration is seen in later enterprises... we know that it is mostly contained in plating in this TOS era.
