Hello again Paul, I've taken a forced leave of absence due to my failure to appreciate a cultural taboo of western society concerning a specific group of 'chosen' people wink But coincidently it seems all you guys suffered a similar fate, so haha :P

Yep that's much clearer, cheers. I think, let me try to reconstruct it, correct me if I'm wrong:

There are 20 masses being accelerated along the length of the pipe. The reaction to this is what accelerates the pipe.

At the same time 20 other masses are free-floating in the opposite direction.

Both sets of masses reach their ends at the same time, where they're both turned around by a 180deg curved track/etc. The reactions from these two turn-arounds cancel each other out.

Repeat indefinately.
