    Uhm, no. That would be a hell of a propulsion method, the definite
    perpetuum mobile - just give it a slight boost and it will keep
    accelerating, wow. Proxima Centauri, here we come! :)
    No, an increase in speed, an acceleration, requires a thrust. If the thrust
    ends, the acceleration will drop to zero, i.e. the speed will be maintained
    (given that there are no other influences, such as gravity).
