In a simultaneous co-counter rotating field of gravitation, it would do no good to make a vertical engine core also in co-counter rotation. Polarization is rotation in one way only. And so the vertical core also polarizes the top half of the warp drive vortex in the center of the Outer Ring engine, and above the Central Accumulator -- monopolar. Polarization of a simultaneous field is the idea.
Polarization of electrostatic creates an electromagnet.
Magneto-electrostatic polarization of light is mass.
Note increased inertial gravitational frequency in the Core, and increased negative gravitation at the outer circumference -- a negative warp bubble, while also including additional (increasing) vortex polarity of accelerating mass.
