- A space elevator. If we ever figure out how to make carbon nanotubes
long enough, we can literally suspend a cable (more like a ribbon,
actually) from geostationary orbit and get stuff into space for an
estimated $300-400/kg (vs. $6000-11000 at present).

I thought the current cost-to-orbit was much higher?

Well, that's the cost range for LEO (mostly). You'd want your solar
power sat in GEO, which will probably cost you, I don't know, eight
times as much or something.

At current launch costs, GEO runs between 1.5x and 5x LEO costs,
depending on launcher used.
