it can allocate itself to the charging station

when the battery is running out. the shelves.

 

so say there are walls, each certain amount of spacing dedicated

to recharging these shelves,

as would a car that is being parked.

 

but the side where the books are, they should be facing front,

 

so people can access.

 

if double-sided, then the wall should be able to rotate as a frame.

 

having some marine animals, none too distracting would be okay as well.
