I have been looking to see if anyone has found limits of the cross section of copper and silver wires for current carrying capacity and for superconductors. I found nothing. I did find this website which talks about critical magnetic field. I suppose one can work out the relationship of critical magnetic field and the ability to carry a large amperage current.
http://hyperphysics.phy-astr.gsu.edu/hbase/solids/scbc.html
Shows a graph of Critical magnetic fields B_c versus Critical temperature T_c and we see the familiar mercury at around 4 K and lead at 7 K and niobium at 9 K. And we see Rh at less than 10^-3 Kelvin and W at 10^-2 Kelvin.
I guess we can focus on magnetic field versus temperature, but it is far more important to focus on current carrying capacity versus temperature.
If we focus on current carrying capacity, what we find out is that superconductivity is a exotica phenomenon and not very important, because silver and copper should be on the diagram shown on that website. Silver and copper would be near that of Rh, rhodium, except would zoom upwards since it has no limitations of a critical magnetic field in the context of that graph.
In other words, when we view superconductivity in context to normal conduction, that silver and copper are the two major conductors of electricity and that nothing as far as superconductors is going to make any dent in that view. The only time that superconductors are needed is when you have a tiny amperage current that you want to maintain.
In terms of energy costs. It is easier to maintain a high current conductor of pure silver or copper at a cool temperature nowhere near 0 Kelvin than to maintain a high temperature superconductor which has only a fraction of the current carrying capacity.
The physics community of superconductivity research needs to change its attitude and view of superconductivity. Not only is BCS theory an utter fakery, but the attitude of researchers blinded to never focusing on current carrying capacity. This attitude leaves the impression around the world of scientists and nonscientists that superconductivity is someday going to replace normal conductivity is a silly idea. Superconductivity is always going to be a dabbling in the exotica of electricity and magnetism.
And what has to emerge is the understanding that normal conductivity of copper and silver wire is the highest we can achieve as far as conductivity.
Once we focus on graphs of Temperature versus Current Carrying Capacity, we see and understand that the future of electricity is in copper and silver as the transport and storage.
There is an analogy in physics that relates to superconductivity, and it is fusion energy. The promise of the 20th century was a fusion energy future, but with the realization of the Fusion Barrier Law, that controlled-fusion (emphasis on controlled) will always take in 1/3 more energy to create it than useable energy released in output.
The 20th century was a century of crazy hopes that could never be fulfilled-- hopes of commercial fusion and everything run on superconduction. The 21st century cuts away those crazy and silly hopes and puts us more realistically what the future is going to be-- no commercial fusion, but we never needed it anyway since geothermal (tapping the Earth's interior) will solve our energy needs, and that normal conduction of copper and silver outbest the superconductors.
