Drive subsystem of a gem-gum factory
The drive system (or energy management subsystem) is an essential subsystem of gemstone metamaterial nanofactories.
Like other non-primary subsystems it would be located in the housing and the internal walls of a device.
The energy conversion inefficiencies in this subsystem are a major source of waste heat (beside friction) so one ought to minimize them.
Waste heat from energy conversion can be more difficult to estimate in an more accurate way beyond just very crude conservative estimations.
Systems of interest
Tips on a molecular mill wheel doing mechanochemistry provide only intermittent torque and sometimes even the wrong polarity.
Connecting wheels directly via mechanical differential would drive back other wheels in the longer frewheeling pauses
or even cancel out opposite with drive in the opposite direction.
The obvious thing to do is to couple a number of wheels as stiffly together as possible with slight phase shifts such that one overall gets a continuous positive torque in the desired direction. Only then one couples various grouped sources together to larger transmission line(s) via mechanical differentials.
The design needs to be such that if one group mill-wheels attempts to back-drive an other group,
then this other group needs to increase resistance to that.
What is desired here is a negative feedback self-regulation.
This is related to the reason why LEDs need resistors in series before putting them in parallel.
Otherwise their slight differences in threshold voltage leads to huge differences in current, leaving some dark and some burning through.
Though we want to avoid resistive dissipation elements as much as possible to stay energy efficient.
Especially at the nanoscale transmitting powers of single chemical reactions with small margins.
So other solutions than friction are preferable
