Thrusite

Thrusite was a synthetic liquid mineral. It formed a fuel when made into an oily solution with moderate amounts of patroleum, a common motor fuel. The solution would be vaporized in a special tank, and the vapor would then be ionized, allowing thrusite fuel to be used as a substitute to hypermatter. Thrusite was first synthesized by Republic scientists circa 40 BBY, at which point it was distributed among the Republic Judicial Forces, who modified many of their Consular-class frigates to use this fuel. By the time of the Clone Wars, however, most Republic Navy warships were designed to use Malastarian fuel or anthracite as cheaper alternatives to hypermatter, and as such Thrusite, by the time of the Imperial Period, was almost exclusively used by some pirate gangs and backworld police forces.
