Plasma Confinement by Pressure of Rotating Magnetic Field in
... Figure 1: Plasma confinement by rotating magnetic field tangential to the plasma surface. The confining rotating magnetic field is created by AC currents driven by applying oscillating (with f ≥ 1 MHz) voltages to toroidal and poloidal gaps (insulated horizontal and vertical cuts) in the shell of th ...

Momentum, Impulse, and Collisions
... Net external force = M totalg " a cm = g " center of mass motion follows a parabola path even after the shell exploded (because internal forces which cause the explosion do not affect the center of mass motion.) Note : Total momentum is NOTconserved because there is an external force. Copyright © 20 ...

Quantum vacuum thruster
A quantum vacuum plasma thruster (or Q-thruster) is a proposed type of spacecraft thruster that would work in part by acting on the virtual particles produced by quantum vacuum fluctuations. This was proposed as a possible model for an engine that could produce thrust without carrying its own propellant. Some physicists working with microwave resonant cavity thrusters think that they might be the first examples of such an engine.
