There is an interesting OU possibility which arises
from observing the "Swinging Atwood Machine" (SAM).
Many undergrad physics classes use these for demos,
and some have been very artfully constructed.

Pendulums can be very efficient anyway- 99.99+% And
the potential anomaly comes from the possibility of
creating slight variations of a 3:1 mass ratio on
either of the two sides of the device....
... begging the question of "why is a three-to-one
ratio so important" ? This ratio pops up in science
from time to time. Mendel found it in plant genetics,
etc. but is there a more basic importance?
...and what could happen IF that ratio were to be
automatically "alterable" on demand (via computer
control)
How on Earth would you 'alter' the mass ratio "via computer control"?
This sounds like Tony Stark's "transistor powered" armor!
You need alter the weights by adding or subtract mass to do that, and if
you don't add back mass at the same height, moving with the same
velocity, as the mass you subtracted, you're cheating: you've just added
or subtracted energy without quite admitting you did so.
In any case the physical mechanism for varying the ratio of the two
masses while the system's operating seems kind of obscure.
in a positive (gainful) way?. It doesn't take
much alteration to get big results in the swings, but
the predictability of the variation in unknown.
SAM’s simplicity of construction and operation is
evident in the Hamiltonian, and it can be modeled
easily using software such as Mathematica - but belies
the complex dynamical behavior when M > m or M < m,
even in very slight amounts.
Is there room for near perpetual motion here ?
(lifetime of the bearings) and assuming everything is
as close to frictionless as possible in the mechanism-
and that the windage has been minimized by a partial
vacuum.
