PLASMA WAVE
The radial planar
guide is the perfect configuration for a magnetohydrodynamic power
generator, which would both accelerate the plasma, and induce electric
energy from it. ("The Plasma State" J.I. Shohet (1971) p145)
The combination of the radial planar wave guide, the capacitive
configurations, and the coiled up cycloconstrictive fields (of stored
electro-magnetic energy) are the main component parts, along with a plasma
of ionized particles, that make up a plasma acceleration device (broadly
similar to a coaxial plasma gun - but, of course, more refined and much
bigger). The plasma, of mainly positive ions and protons would be set in
motion by the recoiling action of the repulsed cycloconstrictive fields
and then accelerated by the oppositely-charged planar wave guide
electrodes, out in a tangential flow through the toroid’s radial magnetic
field. Confinement (which amplifies its force even more) in the wave guide
would be in all directions except at the circumferential duct, where the
aerodynamic shaping of the duct (and like-charges repulsion) would
constrict the plasma and then direct it downward and outward, whereupon
the plasma would blast its way through the toroid’s magnetic confining
field - as a propagated wave of kinetic energy - at almost the speed of
light. 
Some comparative figures from a small 8cm diameter hydromagnetic plasma
gun might give an idea of the energies involved. Using a coaxial tube to
accelerate a hydrogen plasma, and where the conversion of electrical input
to kinetic propulsive energy was rated at 40% efficient;
