Rethinking this whole thing

John:

Something just occurred to me:

Think about JC's test setup holistically: There is a symmetrical arrangement of junctions, but the current flow is in one direction. I think these effects may cancel one another out (or do they double...?)

Example: let's say you have a gold-to-copper junction at one end of the cable. You also have a copper-to-gold junction at the other end.

With the current flow in one direction on any given half-cycle, the heat currents will be reversed (one will heat and the other will cool). They won't directly cancel each other out (because they are some distance apart) but they will lead to opposite Seebeck potentials that WILL cancel each other out.

So, even though each junction might possibly result in a measurable error signal, the symmetrical arrangement of junctions will result in cancelation.

Am I missing something, or does this make sense?

Peter
