Now you have me wondering how an external magnetic field would influence the
process, especially when using conductive particles.
IIRC somewhere I read about moon dust floating above the surface under certain
conditions. Could that be related to a similar process? Here I am not
referring to magnetic effects.

But conductive particles do manipulate hall effect and suppression so this
could be an effect on the ambient trapped gases between the dynamic spacing of
the grains.. would be very interest if the voltage forms in a vacuum.

I wonder if the fact that a different charge appears on the first separating
grains which then biases the process to enhance that effect. I always seek out
positive feedback mechanisms and this might be another.
Something of this nature could make sense since the particles with the initial
charge impacts other particles nearest to them greater than those at a
distance. It would be interesting to determine what characteristics are common
to the powders most active. Do they polarize easily? Is the dielectric
constant the most important parameter? Of course conductive particles could
not behave this way since the charges would leak off.

Hi Harry,
[snip]
When grains made of long chain molecules rub against one another molecules
can
be broken (this should happen with some plastics too). When a molecule
breaks,
it can either form two neutral molecules, or a pair of ions. The latter
constitute opposing charges on two separate grains (each gets part of the
original molecule). Breaking into two charged ions may be more likely in
molecules containing atoms such as Oxygen which tend to hold onto excess
electrons, thus retaining a negative charge.

Here is another story about the same research. Apparently they detected
the same effect with glass particles.

If ions are formed in the way you describe wouldn't these microscopic
charge differences
tend to cancel out at the macroscopic level?
Harry
Yes, I would think so. That's the flaw in my theory. When two different
substances rub together, one will probably have a greater electron affinity than
the other, which would explain bulk polarization of charge, however the same
can't be said for a single substance. I guess that's why they are so puzzled.
Now I am too. :)
