Energy swinging frequency
In reversible computing devices energy needs to swing back and forth. If energy is moved back to the main energy storage source possibly every cycle (possibly through lots of mechanical differentials) friction losses will become too high.
For every stiff material there is a natural resonance frequency characteristic for size. If the swinging of energy is kept maximally local thus minimal in size the natural resonance frequency will be very high enforcing a too high operation speed with too much friction again.
Some optimal point in-between these two extremes must be found. To lower the resonance frequency the springs must be made more compliant and/or the mass must be made bigger.
(TODO: add the scaling law math for the resonance frequency of rotative and reciprocative resonators - how to scale the springs?)
