Electron extractor grid is biased POSITIVE; it is a conduction path and needs its own current-limited isolated supply

POLARITY. In the Gas Processor section of The Birth of New Technology, once electron ejection occurs "the liberated and free floating electrons (117a xxx 117n) continue to migrate toward positive voltage zone (106)", while the newly formed ionized gas atom (104) continues onward through the air intake manifold (109, Fig 3-31). Consistent with the dissociation convention in CA1234773A1: hydrogen attracted to the negative voltage zone, oxygen to the positive.

THEREFORE: an electron extractor grid intended to strip free electrons from an ionized gas stream must be biased POSITIVE relative to that stream. Electrons are collected at the grid; the remaining positive ion stream passes on un-neutralised, which is the recombination-prevention function.

ENGINEERING CAVEAT (my own, not in the source): a positively biased collecting grid is by definition a CONDUCTION path. The collected electron current is a real load. If that grid is fed from the VIC secondary it becomes the leakage term k in the Figure 8 voltammogram of US 4,798,661 and will prevent the drive from climbing the amplitude ladder. The extractor bias must be a separate, current-limited, isolated supply.

PROVENANCE NOTE: the associated "Figure 20YID" charge-extraction drawing (item numbers reported by Scotchn as grid 51, bias loop 54/57/180, gas resonant cavity 110, combustible gas inlet port) has NOT been verified against a readable scan — the image failed to ingest on four attempts. Treat those item numbers as unconfirmed.
