Impulse Drive

The Impulse Drive is a good form of cruising propulsion widely used.

Overview
This type of cruising propulsion is very fast and does not require much energy. The problem with it is that it cant run for long periods of time as it heats up very fast. For this reason it is not used much by Humans or Legoland. It is however used by The Aliens The Plague. The device uses pulses of high energy to propel a craft.

Users
The Aliens - This is the aliens main method of cruising for their ships. As most of their ships are small this form is ideal.

The Plague - There ships are very big and slow and s it is quite inefficient. Their ships however mainly move a traveling speeds so having a highly efficient form of cruising engine is not at all necessary.

Cligates - At B's ship uses this technology for cruising.

Other sub warp civilisations have been seen using this technology.

Trivia
