Additionally, this one of the first times I've seen a description of the skyhook that brings up what I've always been wondering about: Conservation of momentum. Admittedly, since a skyhook would already be in orbit, it can use much more efficient ion/plasma engines, but it will still need to re-boost periodically. Especially since for a long time earth is going to be a net-mass exporter.
