Schwarzschild Kugelblitz Drive; any reason it's not in OA?

Jim Wisniewski's Hawking Radiation calculator says that a black hole with one second left to live still contains 228 tonnes of mass energy; this will be radiated away over the course of that second, getting brighter all the time.

I would be nice to think of a way to capture that brilliance, but it all happens very quickly.

a) The article mentions putting the 'Dyson Cap' in front of the bow of the ship - which would be the front. How that is supposed to translate into forward moment is not explained.

I presume it is a kind of Shkadov Thruster - this works best if the acceleration is long, and slow. Trying to capture thrust from an exponentiating black hole would be tricky.
