  1. The BIG problem with the discontinuation of Electrical Power is that the Nuclear Power Plants (as they go through each of their backup COOLING SYSTEMS in sequence) would rapidly resort to their BATTERY systems. As you might expect, these batteries will eventually run out of power. When this happens, each Nuclear Power Plant will likely be faced with an unavoidable meltdown event.

  3. Electric suspended-from-a-steel-cable elevators will not even attempt to plummet to the ground in the event that Electrical Power is discontinued. That's not how their electric control works. I know, I used to service such elevators. You see, up on the roof of the building, there is a little shack where the ELECTRIC elevator control resides. Just before the large, electric motor in this shack begins to turn (either Clockwise or Counterclockwise), the spring-actuated brake (which prevents the large motor from turning) has to be DISENGAGED by activating an ELECTRIC SOLENOID. In the event that electrical power is discontinued, the Electric Solenoid will no longer be activated. When this happens, the SPRING on the Brake will mechanically engage the Brake. As you might expect, when the Brake is engaged, the steel cable (from which the elevator is suspended) can neither raise nor lower the elevator. The result is that it would be impossible for the elevator to plummet to the ground. Yes, there exists AN ADDITIONAL brake that is mounted onto the Elevator Car, itself. This particular brake ONLY ENGAGES in the event of a freefall event. However, there will be NO NEED for it to engage, because, as I have already pointed out, the Elevator Car will not go into a state of freefall, anyways. There is yet a THIRD reason why suspended-from-a-steel-cable Electric elevators WOULD NOT plummet to the ground (in the event that Electrical Power is discontinued.) On one end of the Steel Cable is the Elevator Car. On the OTHER end of the same Steel Cable is a large COUNTERBALANCE weight. So, even if BOTH brakes (the one up in the roof-mounted Elevator Shack; and the one mounted ON the Elevator Car itself) DIDN'T work, the Elevator Car would still NOT plummet to the ground. Instead, under the influence of Gravity, the Elevator Car would smoothly oscillate Up 'n' Down, until, eventually, the Up 'n' Down oscillations would cease and the Elevator Car would uninterestingly come to a safe stop, somewhere near the mid-height of the elevator shaft. If the elevator in question IS NOT a suspended-from-a-steel-cable elevator, then it must be the type of elevator that is supported, from beneath, by a vertical-action Hydraulic Ram. Since a Hydraulic Ram could care less if electrical power is discontinued, once again, no elevator cars will suddenly plummet to the ground.
