Re: watmath.1678: Mooning Around
A synchronous powersat would NOT be in earth's shadow
half the time;  it's much less than that.  The shadow
goes directly away from the sun, not outwards at the terminator.

Planar platforms wouldn't tend to tumble; they would tend to
align the long axis toward the planet;  some sort of stabilizing
thruster would be needed.

A better thing than putting two power stations on the Moon is putting
three at 120 degree intervals.  That way somebody always has a
good angle on the sunlight.

If the moon were exactly in the ecliptic, there would be a lunar
eclipse every full moon.  It's pretty far off, but my books
are far, far away and I can't give the right number.
