    Machinery to get the power in and out would be electrical field generators oscillating to kick the wheels into spinning. Which might be a single field over the whole fabric, or maybe a plasma field shaped to rotate spikes against the wheels, or maybe doped fullerenes setting a field for each wheel, in the fabric. Lots of brushless motor designs to make in miniature, and lots of new, integrated possibilities. I don't see why the high frequencies have to be lossy in the nanoscale fabric. We've already got very high efficiency MEMs getting pumped at pretty high frequencies. Photonic pumping could be very high efficiency, especially when the receptor is tuned to the incoming photons.

    We already encapsulate all kinds of molecules in fullerenes. As I explained, it's probably not even necessary, but if it is, it can probably be done effectively.

    Gyroscopic effects can always be neutralized by mounting another wheel rotating in the opposite direction.

    I don't see why the wheels can't be a large fraction of the fabric's mass, especially if the driving power is an externally projected electrical field.

    The fact is that the science that used to look like it sharply limited a nanoscale flywheel fabric's efficiency and utility is not really a barrier. Of course there are a lot of engineering problems to solve in making it. But there will be engineering solutions to those.

    The value of such a material is high enough that I expect someone (a team) will succeed sooner than later.
