Talking of 100A and wire size I carry a 3 inch length of "wire" in my wallet
rated at 100 amp continuous 1/8 inch wide and 3/32 inch thick. It was given
to me after a trip round a factory research department and it is (under a
microscope) silver tubes filled with ceramic dust and then rolled until its
thin enough to use. I suppose I should mention that it needs to run at -25 C
it being superconductor. :)
