APM in T.Level III may enable us to create a new type of macroscopic bearings in the form of a passive metamaterial.

From classic to infinitesimal bearings. More layers reduce the relative speed differences. The result has lower friction and higher damage tolerance.

To reduce the relative speed of two surfaces one adds a great number of layers with minimal thickness (un-percievably small - thus "infinitesimal"). Just enough to accommodate some necessary nanomechanics. Those nanomechanics are DMME gears (not bearings) and further structure that make sure that every layer takes the same part of the total speed difference. Note that a single layer can take well perceivable macroscopic speeds without being destroyed. Since there's no static friction and very low speed dependend dynamic friction in diamondoid nanomechanics [TODO add references] the bearings efficiency can be expected to be exceptional.

It is to investigate how a macroscopic infinitesimal bearing performs relative to nanoscopic DMME bearing and how long an infinitesimal brearing of certain size would turn till it e.g. reaches half its initial speed.

As in all products of advanced nanosystems the nanomechanics must (through their structure) provide some redundancy making the design more complicated. [TODO add more detailed Model]
