George: I do agree with you about the technical flaws in Busch's drawings, and I will not waste my time implementing anything like this. After all, his is an 80 years old technology. There would be ways to implement the concept in today's technology, though, as my ME friend confirmed - for a price he said. Think of Busch's as a mental experiment, though. Your train along the equator was a mental experiment, too, and a very nice one at that. I wish you would discuss the extension I proposed. Could you see perhaps the advantage of making the pivot movable and connected it to the mainframe by a spring? Did it reduce the influence of short time jerks? Did you notice any new problems? If you wish I will make a mathematical model in MATLAB including plots that show the movements of your pendulum in all detail - with and without my extension - and submit it to your analysis. It is an interesting system that has its own surprises, I promise! Regards H --- On Fri, 8/21/09, George Huxtable <george@hux.me.uk> wrote:
