I would choose using namespaces to nest the classes.
Clearer code, best designed, improved readability and extensibility, and
over all, increases the level of abstraction, which is a key factor for
ie: I have nothing to do with the class PowerBattery related to 'power'
if you choo to use power::battery, a can later do a power::solar_panel,
and use functions insife power (like power::have_i_supply_for_one_hour())
which abstract me on the specific power supply the instance is using.
I vote for this, if valuable,
