The Earth spins, in doing this it selectively exposes it's
surface to the sun. One complete rotation takes about a day,
any it always will. However, the length of that day will
increase, because the Earth's spin is gradually slowing, mainly
due to the moon... which is to blame for a lot of things.
possible to derive energy from the Earth's rotation. To do
this you get a massive flywheel or two and put them in a
gimbal-type arrangement. The flywheels will spin away,
appearing to move around in their gimbal with a 24hr-ish
period. Now, you could use this motion to power a current-
day-length clock. Interestingly, the clock itself will help in the
slowing of the Earth.

||Uh, I don't think so. You'll accelerate the earth as
much in spinning up the flywheels as you'll slow it
down by their action.
||er... sure? I was thinking that spinning them up
would create a big thing with lots of lovely
momentum, the Earth rotation will then cause the
flywheel's axis to change relative to it's original
position because of the whole precession thing.
||If you spin them up in space using circumferential rockets they shouldn't transfer momentum to the Earth?
||If you want to extract energy from the rotation of
the earth, you need an external "stator". The moon
or sun can be used for this purpose, hence tides.
||The only other known way to achieve this is by using
the Buchanan-Foucoult-Powerball generator <link>
but the physics of this are undercertain.

||Y'know, I've been in club like that...is this the first recorded occurrence of geo-porn..
