He he, except that themoonis currently moving away from us at about
3.8cm/year. As you take energy out of the system there is less to
alter the course of themoonso it tends to travel a straighter path
and thus moves away, well it's a theory...

Err no. The moon is gaining energy by taking angular momentum from the
earth and hence is speeding up and going into a higher orbit. The
earths rotation is slowing down in response to the loss.
