This is one of those random TV episodes that's ripped straight out of master plots to fill time so that they can draw out the arc. On top of that, the whole premise is utterly stupid. You have to believe that "the Founders" had such advanced engineering that they built a steam turbine that can run 140+ years, but... they never thought of adding a steam vent so it could be shut down safely for maintenance. Like an essential feature that's been around since the 1800s? They have a backup system. What does it run on? Surely if they thought of a backup system, they would have thought about what would happen if the main turbine was offline? I won't even get into all the stuff that's crazy if you know anything at all about utility-scale stream turbines, but the silliness of the premise is just common sense. This episode is just one silly contrivance after another on many levels. It's acted out well enough that if you can force yourself to ignore how stupid it all is, it's somewhat enjoyable, but it sure was a struggle. I started the series thinking there might be some smart resolution to it, but slapdash writing like this has convinced me that the big reveals are probably going to be just as ridiculous.
