If you have built a variable angular acceleration engine driven with particle superconducting acceleration, It's easier, and can be reactionless since you now have a braking system. You can also use the black hole as a power source for an engine (see my GIF below). If anyone says that this is a perpetual motion machine, they know very little about physics. (Sure it would last hundreds of years, but so do planetary orbits!!). You could also use this to create a differential field propulsion system, where you fall into a frontal gravity well. Black holes are just powerful enough to do this. Many other things that could be done. E-mail me if interested. Kyle Mcallister
