Gravity works, therefore it is,

but is it friend or foe?


I guess it depends on how old you are and how much you eat.

It's lovely to digress from calling each other names ... couldn't you just harvest energy from the black hole's Hawking radiation? If you're dealing with suspending a black hole in the center of a hollowed-out sphere you don't just need calculus, you need to go all the way to GR calculations - Einstein and the metric and all that. I don't know too much about it to help. But I think the situation can be simplified by having both the black hole and the shell completely spherically symmetrical and imagining the shell moving w.r.t. the black hole instead of vice-versa. Then sum up the force acting on multiple shells.

Now, we need a mathematician to make this work.
