	Many real life systems incorporate features that blend properties; for example, a turbojet engine in an atmosphere is mostly 'internal energy, external reaction mass', using the air, but part of the energy supply comes from the air gathered (to burn with the onboard fuel), and a small part of the reaction mass comes from the combustion products (internal reaction mass). Still, they are usually classed as 'internal energy, external reaction mass' because that's where the dominant effects come from. Some cases will be so borderline they might appear in either case, in which case the practice in the Galactic Library should be to include a cross-reference in the descriptive pages.

	There are a whole range of propulsion systems in both reality and fiction. Broadly speaking, they fall in to different categories based on where the energy comes from, and what they push on (how momentum is conserved). Generically, the mass you push against to get a force on the ship is called the "reaction mass", so where the reaction mass comes from is another factor. We classify propulsion systems in this work with the source of energy being internal to the ship, harvested from natural sources around the ship, or transmitted (beamed) to the ship, and likewise, that the reaction mass can be carried internal to the ship and expelled (called 'propellant' in that case), or harvested from natural sources around the ship, or transmitted (beamed) to the ship.
