I'm not so sure even this would work as is. If there can be no conduction
between the rings, there isn't anything really cutting across the field.
The charge expected would be between the axis and the circumference.

It works because there is a "connecting" mechanism that connects the
rings one to another while the magnet is spinning. The rings are
disconnected before anything stops spinning and hold some of the
charge.

If you have a wire segment from near the axis to the circumference, which
is not attached to anything, it would be cutting across the field while it
is on a rotating non-conductive disk (wood, glass, plastic, etc). But how
to measure that charge? If you attach wires to each end, that is a new
circuit that is cutting the field and developing an opposing current. It's
still a case of the observer being affected by the experiment.

Absolutely. Early on I fell victim to this mistake. I had a disk-
magnet setup and got the idea that since as a Faraday device it
produced enough voltage to light an LED all I needed to do was wire an
LED from the center to the edge of the disk without any "external"
wiring to see if a voltage was there! STOOOPID! The leads of the LED
cut the field just as the disk does. Hence You get +V in the disk and
+V in the LED leads. Around the loop you get... Lets not see all the
same hands... ZERO Duh!

If this design does work, it has the advantage of being
able to run multiple windings in series, for higher voltage (a problem
that plagues the basic Faraday generator).

Have you seen Tesla's design for higher voltage? He uses a copper
braid belt around flanges on two disks essentially hooking them in
series and the two brushes are then on the shafts which means that
they are much lower friction than brushes at the edges of the disk...
