»» Sides beyond the habitable surface areas are devoted to absorption
and amplification of sunlight, and to structural integrity fields.
There are also nearly one billion sunlight gathering stations
within the habitable areas. Even though the amount of sunlight they
absorb is filtered by the inner ring, these stations -- backed by
super-amplifiers under the surface -- provide plenty of power.

»» Underneath the land surfaces, as well as under the ocean floors,
there is topsoil and hard rock, each with abundant minerals.
Also, there are trillions of kilometers of tunnels for the flow
of water, as well as for the distribution of greatly re-amplified
solar power. Also below are trillions (and more) of kilometers of
fiber optic cables, which can carry a mix of television, internet
and telephone signals. Given all the underneath space, the fiber
cables can be much larger in diameter than their "old Earth"
counterparts, and can carry information at greater speeds and
capacities without signal loss or external interference, as is
the occasional case with above-ground wireless systems.

For the Ringworld population density of 0.0022008751 (+/-) to apply to
actual Earth land areas, the current actual total world population
would have to be approximately 327,798 persons.
