 In space, the only real option for propulsion is pure thrust.  Drives of these sort fall into two categories:  reaction drives, which rely on Newton's third law of motion, and reactionless drives, which do not. In space, the only real option for propulsion is pure thrust.  Drives of these sort fall into two categories:  reaction drives, which rely on Newton's third law of motion, and reactionless drives, which do not.
  
-For all space vessels, the only thing that matters is raw acceleration.  Divide your vessel's total thrust by your vessel's total mass;  the result is your acceleration, in gravities.+For all space vessels, the only thing that matters is raw acceleration.  Divide your vessel's total thrust by your vessel's total mass;  the result is your acceleration, in meters per second per second (m/s\[s2]).
  
 Most of these drives can also be used on air, water or ground vessels.  However, those with reactors (fission, fusion, antimatter or nuclear pulse) will probably have unfortunate effects on a planet's biosphere. Most of these drives can also be used on air, water or ground vessels.  However, those with reactors (fission, fusion, antimatter or nuclear pulse) will probably have unfortunate effects on a planet's biosphere.

 No types or names are provided for these drives, for the simple fact that they are completely up to setting fiat.  The closest to any functional concept we have is the idea that if gravity could be manipulated, it could be used to cause a ship to "fall" in the desired direction. No types or names are provided for these drives, for the simple fact that they are completely up to setting fiat.  The closest to any functional concept we have is the idea that if gravity could be manipulated, it could be used to cause a ship to "fall" in the desired direction.
  
-The best that can be assumed is that these drives will suck a //lot// of power from the ship's powerplant.  The exception is the TR0 reactionless drive, which is assumed to use some even more exotic principal to produce thrust, like magic.+The best that can be assumed is that these drives will suck a //lot// of power from the ship's powerplant.  The exception is the TR? reactionless drive, which is assumed to use some even more exotic principal to produce thrust, like magic.

 +Mass is per Newton of thrust.  Cost is per kilogram.  Volume for all engines listed above, in cubic meters, is equal to their mass divided by 75, and includes access space for maintenance to be performed.
