I have an interesting question. Why do Jump Drives need jump fuel? Why are their reactionless maneuver drives that run on only power from the power plant? Why doesn't the Maneuver Drive get the fuel instead? We could call it "Maneuver Fuel". Now "Maneuver Fuel" would be separate from fuel for the power plant. Fuel for the power plant is a source of energy, a fusion reaction occurs and the power plant fuel gets turned into something else while energy is released, the power plant then channels that energy into the various ship systems including the maneuver and jump drive. Now the maneuver drive throws hydrogen out the back to push the ship forward, while the jump drive bends space so the ship can enter jump space, I don't know why the jump drive required fuel to do that and not just energy from the power plant, and why does the Maneuver drive require only an energy input, I would thing this arrangement would be the opposite. Why not?
