' Wrote:Where's the <strike>catalytic</strike> cracker?
Or is the big chamber it?
you mean the process known as 'cracking' which creates water from oxygen and h-fuel?
That's caused by the combining of oxygen and hydrogen molecules during sparking at the rear of the chamber, when the fuel stream is 'ignited' it creates water vapor which gets pulled down the pipe at the back of the chamber and is moved into the water tank for storage.
Heat, Radiation, and Electromagnetic energy from the fuel stream ignition is absorbed by the 'hamster wheel' at the center of the chamber, which converts it all into electrical energy and stores the leftover energy in the power cells. Energy that isnt stored is consumed by the electromagnetic coils lining the chamber - which condense the fuel stream from the injectors and propel it out of the rear of the engine towards the igniters.
Altering the coil frequency (i.e. the rate at which they activate and deactivate) increases the velocity of the fuel stream, resulting in the ship moving faster. Reducing the coil frequency slows the stream down, resulting in the ship moving slower.
