The point, Dave, is that these solutions are far lower cost than solar power
satellites; are incremental investments to existing infrastructure; and, are
being planned by organizations with hundreds of billions to spend.
I do not expect a planetary power grid in the next two decades; geopolitics and
the need to develop superconducting power cable assure that will be an end of
this century sort of effort.
Again, the point is that such solutions are lower cost and incremental to
existing economic needs: as Keith has observed, power loss in existing cable is
expensive; which is why transmission companies are experimenting with
superconducting cable to replace existing cable.
The solar power train has left the station; solar power satellites were never
even on the track.
