No more posts or objections? So let me summarise all the properties of a superconductor, which have to be explained by the correct model:

1. The charge carriers must not scatter (even BCS concede this)

2. Once an equilibrium current flows, the superconductor must be a perfect dielectric.

3. When the emf increases, the charge carriers must be able to increase their drift velocity WITHOUT increasing their kinetic energy (It is strange that John Bardeen, the co-inventor of the transistor did not pick this up).
