I wonder how practical that is, versus the incredible expense?

On Turesday there was a huge power outage in Florida caused by a shut
down of a nuke plant for safety issues.

all public buildings nationwide should be required to have a minimal
back up power capability.

to run emergency lights, get elevators to ground level, and stuff like
that.

people stuck in elevators is really dumb in this day and age

Elevators in our condo were update last year with a feature that uses
gravity to automatically return them to the bottom floor if the power
fails.
No emergency power required.

Hmmm. I thought most buildings already had that -- at least for basic
systems like exit and power-failure lights. One of the lessons learned in
the first Wold Trade Center bombing was that a central emergency system
generator, if destroyed -- which it was, can't do any good when the power
failures. The WTC replaced stairway lights with local battery-power units
which did work on 9/11.

I see battery-powered egress lights in restaurants, churches, stores, etc.
now. Something for elevators sounds a bit more expensive especially for
tall buildings, but even a system that returns the elevator cab to the main
floor could be powered by something like a car battery for the bit of power
and limited time required.
