How would you improve the singularity engine?

TG's works by having it start small, and get larger as it's fed/shot by a particle accelerator. Of course, TOO big and it escapes containment.

I think the singularity should only ever escape via gross negligence or intentional sabotage, compared to the TEG it already has several downsides and is much more dangerous. Punishing people for trying to get more energy out of the engine should be something less disastrous imo
