I am not sure where this question is going and I am pretty sure that my terminology is wrong. But let me at least start and I will correct my question as we go along.
Say a spaceship was travelling at near the speed of light relative to us.
Now inside of the spaceship you have wires that provide energy to the engine that is under the hood in the front of the space craft. The space craft is travelling directly away from us and towards its "front" ( the engine is the farthest point away from us, the rest of the spaceship closer ).
Without energy ( electricity ) the engine can not work.
When the spaceship accelerates and now is near the speed of light, the electrons in the spaceship still need to move around ( at the local speed of light ) and drift towards the front at a rate suffient enough to power the engines. However since it moving at near the speed of light I would think that the natural tendency of the electrons would drift backwards towards us.
Another way to look at this is that electrons move around in somewhat arbitrary motion at the speed of light, the drift usually would push from source to sink, however since it is travelling at the speed of light wouldnt an artificial sink be produced?
