Small thrusters have extremely low efficiency, sometimes not exceeding 10–15 percent. Such an engine would use considerable amounts of electric power. This could potentially impact the payload and orbital service life. How to proceed with specific space propulsion systems?
Use the Thruster 50 times. You will be given the Thruster ability as part of the story during Connections when inside of the Conservatory. Press and then to select it. Press to use it. You’ll be able to boost in whatever direction you’re going when using it. Use the Grappleshot to board an enemy Ghost.
When the bow thruster is running, the resistance (and, hence, voltage drop) along the light cable is such that the current is limited to a couple of amps and so the cable is not overloaded. When the bow thruster is not running, the light cable trickle charges the bow thruster battery from the house batteries.
That battery is charged by the main engine alternator system with a third output from the splitter device that separates the starter and domestic charging circuits. When on shore-power, again a third outlet from the mains charger runs to the bow battery. All cables are significantly 'heavy duty'.
