I happen to think that SPS is the most elegent solution but I'll play
along. But first, don't neglect the SPS thermal proposals which don't
use PV cells.

Thinking outside of the box, we could tap electrostatic field
differentials but I think they are stonger in LEO than at GEO.

We could also seek to tap into the Earth's momentum as a source of energy.

That taps me out for the moment. I still think that these sources are
a bit of a reach when we consider that the Sun is pumping out all of
that energy, so no need to rob the Earth of its spin to provide us power.

As for He3, Andrew Case, one of our list members provided us with a
very thorough explanation about the difficulties involved, and in fact
his post was prompted by a request from another student in your
program. See here:
