So you have to find an interaction unexplained by conventional science to find PM...
I don't disagree with that, but I would suggest that such an interaction could possibly be unexplained simply because it is a type of interaction that has just not yet been considered rather than that the accepted scientific laws currently on the books are incorrect or wouldn't apply.
In other words, the empirical laws in the books might actually allow for such a thing already and the scientists and others could just be ignorant of that.
This could mean they already have the keys to the kingdom but just don't know how to use them to enter in themselves and would attempt to bar others from entering in due to their own ignorance, hypocrisy and self-righteousness.
Bang-on, IMHO mate.
If it's possible, then it must be so
because of the standard classical laws, not in spite of them. The exploit
depends on the variability of CoM in relation to CoE in rotating systems, due to the variability of MoI circumventing the restrictions of mass constancy in linear systems.
As others have noted, we could create KE if we could reshuffle the balance of M and V for a conserved P; transfering or converting momentum into a mass reduction and consequent velocity and KE increase.
But in a linear system, mass constancy precludes this - the balance of M to V in the momentum of a body at rest is locked down by the invariability of M.
However in rotating systems, M is replaced by MoI, which
is variable - for instance as a function of radial distribution of mass.
And we already
can create RKE by dynamically reducing MoI... we just can't accumulate it cyclically, yet...
But Bessler's success is proof positive that such an exploit
is possible, if we can find it.
If we can, then we'll be able to reshuffle the
conserved balance of MoI and angular velocity, to create an effective rise in force (if MoI goes down and RPM stays constant, torque must rise). In other words, we can trade a drop in MoI for either component of an F*d boost - torque, or displacement / time (angular velocity). Whichever variable is held constant, the covariant quantity must rise to conserve net momentum.
This is consistent with the general assumption that local CoM is more fundamental than local CoE - indeed, the latter merely being an incidental consequence of the former in most cases.
If this approach is correct (and it appears to be the only one on the table in terms of classical mechanics), then momentum is
so fundamental that CoE can be 'conserved' right out of existence. Energy schmenergy - so long as all the momentum's accounted for, nature's happy.
In a nutshell, momentum and energy have different dimensions, yet the latter is wholly dependent upon the former - P=MV, while KE=1/2MV^2. Thus CoE is entirely contingent upon the balance of M and V in the momentum terms; if that balance shifts, then for a given P, KE <> the length of a piece of string... we simply need an MoI variation that matches the amount of energy we'd like to create or destroy, and some means of accumulating it over successive cycles.
As such, the path to OU could be no more than an addendum to the page in every physics textbook explaining the ice-skater effect...
