The momentum borrowed by the pendulum will be returned once the pendulum comes to rest. At that time, the earth will spin faster as required to keep the total angular momentum constant.

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.

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. Nigel
