I've always wondered why cell doors in Science Fiction are always something that fails when the power goes off.

What ever happened to good old METAL doors and bars? Like really, a metal door, with a metal lock bar, does NOT easily open if someone trips the wrong breaker.

But I like the layout for the most part, but I think you should be able to cram far more criminals in there.

My personal favorite method for holding inmates for sci-fiction transit is in small life support pods. Stack them in like cord wood, and if anyone manages to get too wound up in their small coffin sized cells, then just lower their life support levels till they go back to sleep.
