13. Quantum Vacuum Plasma Thruster

http://en.wikipedia.org/wiki/Quantum_vacuum_plasma_thruster


Theory of operation


The research team claims the "Q-thruster" utilizes the quantum vacuum fluctuations of empty space as a "propellant". The existence of quantum vacuum fluctuations is not disputed, because experiments with the quantum mechanical Casimir effect have unambiguously demonstrated that quantum vacuum fluctuations do exist. What remains to be proven is that these fluctuations can be utilized for this practical purpose.[4]

The Q-thruster operates on the principles of magnetohydrodynamics (MHD), the same principles and equations of motion used by a conventional plasma thruster. The difference is that the Q-thruster uses the atomic particles spontaneously produced by quantum vacuum fluctuations as its propellant. The atomic particles produced by the fluctuations are subsequently electrically ionized to form a plasma. The now electrically charged plasma is then exposed to a crossed electric and magnetic field, inducing a force on the particles of the plasma in the E×B direction, which is orthogonal to the applied fields. The Q-thruster would not technically be a reactionless drive, because it expels the plasma and thus produces force on the spacecraft in the opposite direction, like a conventional rocket engine. However, this action does not require the spacecraft to carry any propellant. This theory suggests much higher specific impulses are available for Q-thrusters, because they only consume electrical power and thus are limited only by their power supply's energy storage densities. Preliminary test results suggest thrust levels of between 1000–4000 μN; specific force performance of 0.1 N/kW, and an equivalent specific impulse of ~1x1012 s.[5][6]
