The technology dates back to 1925.

Probably not.  The problem is cost.  Musk and Co will probably get the
cost to GEO down from the current $20,000/kg to $2000/kg.  That's
still ten times to much for power satellites to make economic sense.
Skylon can probably get the cost down far enough and deal with the
volume (a million flights per year).  The capacity of the aircraft
industry would have to about double to make enough of them.
