Power Grid Improvements

[Roomba]

As far as I can tell, the first two suggestions seem to be largely aimed at punishing engineers at doing too well at their job and getting a good engine hellburn. I don't really know why having the SMES explode is considered an interesting failure state, it seems a pretty crippling issue to me. Furthermore, having the engine start hotwired and require rigging up to the SMES makes it a little too easy to cause a lot of damage to the station through sheer negligence, which I don't think should really be encouraged. Not a big fan of these suggestions.
