Hi Anthony
It isn't a matter of even needing a large gear ratio. The force and
motion of a flywheel are at 90 degees. You push this way and it
moves that way. The only way to get it to work
is the allow the flywheel to change angle ( remember vectors at 90
degrees
when multiplied together create a 0 length vector = 0 power ). As the
flywheel
changes angles, it will precess towards the location that its axis is
lined
up with north and south. End of game.
As for slowing the earth, when he spins the gyroscope up, it will
change
the earths rotation slightly but monentum will still be conserved.
Regardless
when the flywheel stops, it will be restored. If the flywheel is moved
at 90 degrees,
it will add or subtract to balance the original change. This is the
law, we can't
change it.
The only way to permanently change the earth rotation would be to
spin
a flywheel up and then send it off into outer space. The total
momentum
of the flywheel and earth still doesn't change, it is just that we
will never see
the flywheel again. Anything we do on the earth that stays on the
earth
doesn't change the total momentum.
The moon is slowly slowing down the earth but the total momentum of
the
earth moon system doesn't change. In the case of the moon/earth, the
moon is moving to a higher orbit.
