LA-LIB
The LA Library is large
Card Catalogs are gone long ago.
You better brush up on
Finding books on the Shelves...
Before the power fails...
Colletions are on different Floors.
Lots of Branch Libraries, too...
Of course, if the Grid fails,
you'll need a flashlight...
What about your phone?
The simplest way to build
a Shake-to-Charge phone charger, would to build
several shake flashlights,
and observing battery polarity,
connect several in series
to an Automotive USB
power adapter.
The adapter would condition
the battery voltage to 5 volts
for your phone ...
So you can check when
the cell towers go back online.
Of course, Remote Cell Towers
use Methanol Fuel Cells as backup...
Toshiba made a methanol
phone charger years ago.
Maybe you should get one.
