Even at the fairly large element sizes chosen for performance
estimating, this prospective performance is startling, though the
example scale is too large to be maximallly effective. Using nano-
technology the performance could be improved by orders of magnitude.
For example, Casimir cavities of width less than 1/10 micron, 100
nanometers, would be necessary to achieve significant inertial mass
reduction. This can be achieved by making smaller beams, but also by
extending into parallel slits of width less than 100 nm, rows of
planar protrusions from the beam, protrusions which are of less than
100 nm width extended from beams which are on the order of a micron
wide. When this is done only a percentage of the pendulum mass is
involved in actual inertial mass reduction, but, given the cubic
power distribution of the zero point field, the effect should grow by
at least the inverse square of the slit widths. The limits to
advancement of technology of this kind are probably features on the
order of 10-20 nm.
