My theory made sense in my head.
Thanks for bringing forth the facts John. I guess I should edumicate myself a little better on the hows and whys of electrons. :-)
Follow Ups:
an Indium based one has only 28% the resistance of copper wire. The more connections the worse it does become, simply because the solder forms an interface between the connector and the wire. No solder and after a few years that crimped interface corrodes, at least in my experience.
Sorry, reference can be found on the Indium website. The indium Corp, also makes standard type solders, SN62, etc. so you can easily make comparison.
most of the solder sold under the indium name is not made of indium :)....the ones i found are like SAC 305 or Sn63 Pb37 some with silver, mostly traditional mixes :)

Indium is found mixed in with lead in nature and is a bit difficult to extract. Hence the indium corp makes standard lead solder too. Their website lists conductivity of their solders. I honestly forgot the high conductivity formula, except for the fact that it was expensive. I have some somewhere but have yet to make a controlled listening test.
Also interesting to note much lower melting point. Might be good for smd stuff.

sn62 conductivity 11.9%
97 In, 3Ag. 23%
100 In. 24%
These indium formulations not common at all and pricey
EBay has a pound of 97in3ag solder. Buy it now for $4950!!!!
that is probably not the source i want to use...
