You need to be thinking of momentum instead of energy Harry. The two are not interchangeable.

You can't build a mechanism which extracts more energy from the rotation of the earth then you put into the mechanism. On the other hand, if the goal is to lengthen the day rather than generate useful energy, then such a mechanism would be considered useful. :- / harry On Sun, Feb 9, 2014 at 3:09 PM, H Veeder <[email protected]> wrote: ...and the rotational speed of the earth will descrease as a consequence. harry On Sun, Feb 9, 2014 at 3:06 PM, H Veeder <[email protected]> wrote: Focault's pendulum could be used to extract energy from the rotation of the earth. harry On Sun, Feb 9, 2014 at 2:15 PM, Hoyt A.

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
