Impulse Drives

Impulse drives are a type of subluminal Starship Drives. They all create propulsion by ejection of some matter in the opposite direction of the intended movement. 
Impulse drives are the simplest technical solution, creating a decent acceleration but are notoriously dependent on vast amounts of fuel and are rather inefficient compared to other solutions. Nevertheless, almost all subluminal acceleration is created by some kind of impulse drive or another.

A relatively rare but noteworthy kind of impulse drive is the class of electron-repulsion drives. 
Instead of expelling heated matter, these create a plasmatic Meisenbach field. The surplus electons created by this field repell each other, thus creating the wanted thrust. Electron-repulsion drives deliver low acceleration values, but offer a fuel efficiency unmatched by other technologies. Therefore, E-Rep drives are the preferred solution for long-distance exploration vessels. 
The decaying electron field they leave behind, though, is a minefield of exotic particles. Therefore, electron-repulsion drives are only cleared for use outside the local Mandala orbit. 
As the Meisenbach field is created by sub-atomic breakdown of the Ourania spindles, it is consuming fuel in the widest sense, and is classed as an impulse drive.
