I just read your paper on open Air Habitats, in which you cited my posts
to this list in 97 in the following paragraph:

Another effect of this ion flow will be that since each pole will
attract oppositely charged particles, in the center where the flows
interact, you will get a large amount of dischaging which could
interfere with communications across the hub. I'd suggest the addition
of a membrane or grid of some sort that would generate power from this
potential difference. Having two grids, one across the north edge of the
hoop, and another across the south edge of the hoop, with a circuit in
between would pull a large amount of energy from the solar ion stream,
and sheild communications within the hub from interference.
