**************Oh that would be great!  Thank you for that.  I dug up my old "size grande" chips today, though they have more like 3mm x 3mm x 3mm cube elements.  I may not get to the point on the carousel of doing anything with them anyway until after mid next week, due to other remaining post-vacation catch-up work.

*************Mebbe, but it needs to be examined in the form that most easily complies with the hypothesis at hand, and so I am very much intent on trying the surface charge application test.  Presumably, an object emitting N monopoles would be repelled from a N pole of a regular magnet and attracted to the S end.  Its just that for the emitter, the force would be isotropic, like an electron.

************I can see how Bi2Te3 doped for thermoelectric use could be on the hairy edge.  The Peltier effect requires the Z coefficient, but also current.  With such materials, Z can be made high (>>1) but the conductivity goes to nuthin'.  So my guess would be that if all of this holds any water at all, the best Bi2Te3 would be marginal for thermoelectric use, probably under-doped.  But I DO also have a few kilos of Te and a kilo of Bi lurking as well in my chemistry set...

**************Never tried that... but dang, what an excellent idea.  A flat plate cap with Bi2Te3 would in theory produce a field like a bar magnet, wouldn't it?  N monopoles emitted from one face, S monopoles from the other?

I have to confess, it has been SO long since I tried to exercise my peabrain with monopole gymnastics, I forgot the burn.
