And a space elevator is as far away as sustained fusion. We just don’t have the materials science. We have a material that might work, but no way to fabricate it in the lengths or quantities required, which is as good as not having it. Not that clearing every single equatorial orbit below geosynch is easy. A space elevator might require clearing ***all*** orbital infrastructure below geosynch since all of it crosses the equator and can hit the space elevator. We’ll see cheap sustainable fusion first.
