Re: Shape of the Orbital Wires?

| Around a planet such as Earth, orbiting tethers will naturally stretch out perpendicular to the plane of their orbit: one end pointing at the planet, the other pointing away. Around Jupiter or brown dwarfs, the gravity gradient is such that this doesn't work except very close to the planet. So you need another means of stabilizing the cable so that it presents the greatest cross-section to the magnetic field. I've heard proposals such as loops or rotating tethers for this scenario. The tethers I describe in Permanence are, of course, a bit fanciful and exaggerated. But I think a loop, traveling edge-on to the field, is one possibility. |
