Eh???

Well, it'll probably still be moving when the sun explodes, so I guess
that's close to perpetual motion.

Actually it's no "closer" than any other process--it follows same
thermodynamic laws--it's just that the losses are relatively small with
respect to the total mass. It (assuming the reference is to the earth I
presume) _is_ slowing measurably albeit granted it's on a relatively
long time frame.

Well, maybe it's not pure perpetual motion, but it'll probably keep going
longer than anyone will be around to see it finally stop. In any case,
without visiting the link, I'm pretty sure it's closer than what they have.
