Ja and I disagree, at least on earth. I havent gone over the
equations in the paper that Robert B. referenced, and I really
need to do so when I get the chance, but my calcs suggest we
arent there yet, and I havent found an error in those calcs.
Yet. {8^D
Mars would be good for an isosynchronous cable tho.

One was in tension, the other compression. Not directly comparable.

Useful. We would think of uses.

Sure would. That unsuccessful experiment with the shuttle where
they tried to reel out a long cable in orbit to generate power was
to show just this effect. spike
