Is the moon leaving, or are we shrinking by 38 mm/year

Obviously there's tidal gravitational forces continuously at work, as
otherwise something as massive as the Earth/Moon union would become
one.
A real sidelight, but I don't think they would "become one". I think
that
in the existing system, there is enough angular momentum that there is
no
way a single "partially liquid" body wouldn't spin out one or more
lobes.
You might jam the two together, but I don't think they'd stay together.
That's certainly a good thing to know about.
Any better notion upon my village idiot efforts at obtaining the
kinetic energy requirement for just sustaining the lunar orbit?
Zero additional energy should do OK. The solar wind boosts one side, and
retards the other. The earth would have to freeze solid for all eternity,
of course. All the way down to the core. Might as well tidally lock it as
well.
Otherwise, it'll just continue to gain angular momentum from the Earth.
Should pretty much stop the recession...
