Hi Everyone,
Indeed, timing and delaying the effective action of a force might very well be the key here. According to George B. Airy, such effects actually provide for at least the theoretical possibility of PM. If you haven't already, please see his 1829 article posted on this site:

Here is my paraphrasing of Airy's article:
PM is not possible with the known forces because the expression Xdx + Ydy + Zdz is integrable "per se." In other words, the hypothesis of Conservation of Energy holds for any 3-dimensional field of force - i.e. for space as we know it. Since the expression above is a complete differential for all the known forces, PM is incompatible with those forces.In the above reasoning we presume that the magnitude of the force acting on a body at any instant depends on the position of the body at that instant. If however the magnitude of the force should depend on the position of the body at a prior instant, then the theorem would no longer be true.
For a body moving in a closed path, each time it returns to the same position, its velocity could be either higher or lower than the time before. If it were higher, it would increase until the force of friction held it constant.

: I was playing with increasing velocities by spiraling weights in a coil to see if I could derive more energy than from freefall. I put a BB in a tightly coiled copper tube , arranged vertically. It had about 20 feet of travel. When it came out the bottom after all that swirling about, it was barely moving!
: BUT, it took a LONG TIME to get to the bottom!!!!
: I propose that if you can slow the descending side you can have more weight than the ascending side.
: Now how can we do that?
