  Large flywheels are well known to be terrifying mechanical monsters, despite just being a spinning disc

  A couple decades ago I worked at a place that did power generation turbine controls.

  One thing I worked on was a redundant sync check for connecting turbines to the grid. A turbine has to be brought up to speed, about 3600rpm in the US, before being connected to the grid. The sine wave coming out of the generator needs to match the sine wave on the grid.

  If they are mismatched when the huge breaker closes, it’s not a shock or fire hazard, it’s an explosion hazard.

  Dams are scary too, I just hope people are able to decommission them slowly when the time comes. Otherwise the deluge is going to suck.
