cost. I suggest that we import bearings, generator/motors, and carbon
fiber or Kevlar arms/containers from Earth to the Moon. Each unit

Adding mass to the system does not help with energy storage.

If you've got a given mass of carbon fiber in 'arms', then you gain
nothing in terms of energy storage capacity by adding extra mass to the
ends.

Ian you are suggesting that Brad do RealWorld math. His brain can not handle
such data.

Earl Colby Pottinger,
Tell you what my brown-nosed and otherwise dumbfounded friend. I'll
put up my LL-1 multi-megatonnage worth of massive counter-rotating
flywheels as per say up against your whatever multi-kg flywheel(s)
that's having to be associated with the surface gravity and
horrifically nasty dust of our salty as well as reactive moon, and
perhaps with each of us having a laser cannon pointed at one another
should tell real soon which of these flywheel methods offered the most
stored energy.

Exactly how many TJ or rather hundreds of MWhr worth of energy were
your wossy little flywheels going to store?
