A plasma thruster is any thruster that uses plasma to provide thrust, hence the name. They are usually used on spacecrafts to push the craft into the right orbit. Plasma is the fourth state of matter. It is VERY hot and can be pressurized and can be controlled easily using electrodes and electromagnets. So, it's pretty useful for thrusters. The gas that will be turned into a plasma goes into a chamber. The gas is then turned into plasma by either direct current, radio waves or microwaves. Plasma can also be made by heat, but it would have to be really hot and would be very inefficient. The plasma is then contained by electromagnets. The plasma is sometimes heated even further to be more pressurized and provide more thrust. Then the plasma is made to shoot out in a steadyoutwardway by using electrodes or magnets. And, that's how plasma thrusters work.

my thruster bike cost is $80

Plasma has a refresh rate of 60Hz but the pixel is pulsed 12 times per hertz resulting in the equivalent of a 720 Hz.For more fallow this link http://www.digitalhome.ca/forum/showthread.php?t=73892

An azimuth thruster is an engine and ship's propeller in a pod which is azimuth adjustable.
