You can't fight entropy. Somehow, this still won't convice my boss a neat desk is wrong...

No, but it's fun trying to figure out why Xiao keeps bugging us with this "wheel with the pool balls falling out".

Actually, the sad irony is that the wheel runs *longer* as the balls fall out, not in spite of it. I think this guy has started it running, seen it running for such a long time with all these balls falling out, and thus concluded "Hey, if I could stop the balls from falling out then the wheel would run for ever!!!".
Going Down: Ball -> Wheel
Going Up: Wheel -> Ball
The system he is talking about wont work even if it were frictionless because whenever you move the ball into a different section you either need a slope or a wedge. The slope takes a little bit of gravity to get you rolling sideways, the wedge steals a bit of your angular momentum instead. But when the ball rolls back into the wheel the energy in its horizontal velocity isn't being properly captured (because the ball gets stopped at the gate), and thus that wastes a little bit of energy through each cycle.
In the attached diagram the little red bits are energy used to move the ball between sections that he hasn't re-captured somehow, and thus the system is losing energy before you even consider friction.

Almost forgot...

Because it'll ensure he never looses his high scores again.
