Solar heating sets up a set of convection cells - very simplisticly ;
air rises at the equator, falls at approx 30 N rises at 60 and falls at
the poles. Without coriolis these would just go north-south. With
corriolis they end up with a substantial Westerly component; see
http://en.wikipedia.org/wiki/Global_wind_patterns. The energy that
drives this system is solar radiation from the sun heating the earth and
causing the convection currents, and it is this that blows ships and
windmills.
But, you will then ask, what drives the 300 mile an hour winds on
Jupiter which is so much further from the sun? It turns out that we
dont really know, but it appears some people think that thermal energy
from within the plant might be driving them.

I would say the trade winds are a good example of the extraction of
energy from the rotation of the Earth. Heat certainly is generated
and Man has used these winds to cross the oceans for years.
Nigel, what is the external body in the case of trade winds that is
present for the extraction of energy from the Earth's rotation?

You're undoubtedly right. It makes me wonder if these simple
newtonian problems from dynamics 101 can be so
mind blowing, what's the chances of analyzing these bizarre
non-linear maxwellian/relativistic/quantum mechanical kinds
of problems.

As I found out some years ago when I spent a couple of months on
this, whatever system you come up with, when you actually go
through the maths it comes up with the same answer, and that is
that you cannot extract energy from the rotation of the earth
without reference to some external body. You can come up with
complicated systems that makes the maths more difficult (our
gyroscopes on railway tracks travelling between the pole and the
equator was particularly 'interesting' to analyse. I'm not sure
that 15 years later my brain is still up to it, that why I get my
son to do it), and that is what may have happened with the RAR
machine. Its complexity hides a mistake in the analysis of the
forces and moments which made it appear that it was possible to
extract energy from the earths magnetic field.

You make an excellent point Nigel. Even an artillery shell
that has its apparent path diverted by the coriolis effect is
not given extra energy from the earth, but instead travels in
a free path. The earth rotates out from beneath the original
aim point. A similar process must be happening to the air
flowing due to wind.
