True Dax. Grimer plans on eliminating that loss with a one way clutch or a stop as in the video. This only works for the start up and once in rotation it would be useless. I guess maybe I just don't get it. ;)
That is true, however, if there was enough energy for the reset (and I do not believe there is), you could capture the energy of the rotation, and bring the wheel to a stop every 180 or 360 degrees. All the energy you capture is available for use, as the mechanism would reset itself.
I wanted to post a pic, but the attachment problem is still not resolved. Since others are having the same problem, I suspect it is a problem with the site, not my personal limit.
Grimer, regarding the first video: on the first bounce, the position the right hand ball of the compound pendulum reaches
-0.359m. This is the point it has no energy left, and begins to ascend. The simple pendulum, after its perfect bounce and no wind resistance rises to
-0.359m. Again this is the point at which the rising pendulum has no energy left, and gravity pushes it down. This is measured by the sim. Do you think it a coincidence they both reach that exact point in simulation? This leaves no left over energy for rotation.
