Asking out of curiousity. All answers appreciated.
You have a machine that generates micro black holes on the outside of it which evaporate quickly and then are immediately generated again upon evaporation.
You make sure a part of the machine is next to where the event horizon of these micro black holes would be. Each black hole evaporates before the machine falls into the event horizon.
From repeatedly being pulled toward each micro black hole, never falling into the event horizon, could this generate movement of the machine?
