"I was just wondering about the feasibility of using energy collected
at one location in space to power equipment in another location, via
the same kind of rectenna set-up proposed for getting energy to earth
from space. It increases the complexity of the overall system, but if
the rectenna has a lower mass to power ratio it might be worthwhile
for systems going to high-delta-vee locations."

Sounds great to me.

I'm just a little concerned about the long-term reliability of the energy
source. Back-up/emergency energy should be always available anyway - just in
case - so this needs to be kept in mind whatever the scenario, of course.
