Although that one's a little ridiculous, note that you *can* make some
kinds of alterations to an orbit by doing this sort of "pumping" with
a tether and an end mass. In particular, provided your orbit is already
at least slightly elliptical, you can make it more elliptical -- raising
apogee at the expense of lowering perigee -- by reeling out the tether
upward at apogee and hauling it back in at perigee.
