sadly black holes go to something like 42% conversion (source: some minute physics video i think)

That's quite interesting. Is it because of the light produced when the materia starts spinning around in the accretion disk in very high speeds? I doubt hawking radiation would do anywhere near that much

No, It is actually the light produced that we can actually use as a energy source, the limiting thing is, before completely loosing its kinetic energy to frictional heat, stuff falls into black hole, from where we can not get anymore energy back. If black hole is stationary, then its 6%, and if its spinning (and assuming the fastest spinning theoretically possible) - 42% (spinning black holes are smaller and have smaller radius of no-return

Ahhh alright I was thinking the black hole converting mass to energy for itself, not as if we were to try utilize it

we can't let the noble black hole keep all ye energy, ye shall liberate it
