Tether power sources?
Hi Lee
Tapping a conducting tether for energy extracts it from the orbital energy of the object itself, so that's a bit self-defeating isn't it?
But there maybe antimatter lurking in the magnetospheres of the Jovians, captured from cosmic-ray collision by-products. Maybe.
Better off just using fusion power since there's planet-fulls of He-3 out there. But even ultra-light solar collectors, or beamed-power from "roaster orbit stations", might be viable too.
Dunno about the giant Space Wheel colonies. Arguably they're analogous to skyscrapers in our present cities, but at billions of tons apiece...
