Quite possibly. I'm not concerned with power transmission so much; that's just engineering, and the tiny Centennial Challenge teams were doing well enough over a few years that it seems quite soluble. We will probably have UAVs flying on beamed power regularly within a few years. The tether materials are obviously the long pile in this tent. We have theoretical materials that will work, which is great, but we really need practical materials. The day you can go buy nano tube thread you can formulate an actual timeline for a space elevator. Until then, its only a dream.
