Given the way electrostatic charge can accumulate on
moving vehicles maybe Hamish Robertson is getting closer to
the facts:
The most likely place for accumulated charge to settle is
at the ~ 6,000 square centimeter Helmholtz Layer Interface
of the electrodes/container vessel in the Joe Cell.
Lots of ReDox possibilities there, even if it only spits out electrons
near the air intake without actual connection to
the Throttle Body, or for us older folks the carburetor.
