Impulsed Plasma Engine

One of several technologies copied, studied and refined from an Arlekian ship that had crashed on the Moon millenia ago. Some of the components in the original Arlekian engine were made of materials of unknown origin but suitable replacements were found. The basic principle behind the engine is like that of a hydrogen fusion reactor (a controlled hydrogen bomb) where hydrogen (the most abundant element in the known universe) is superheated and collided together; releasing even more heat and some power in the process. The 'exhaust' is any spent and reacted plasma released in controlled pulses at high frequency.
