Title: Comment on "Case of thermodynamic failure in the Ginzburg-Landau approach to fluctuation superconductivity"

Abstract: Jorge Berger shows theoretically in the paper Phys. Rev. B 109, 024501 (2024) that according to the Ginzburg-Landau theory the persistent current can create the persistent voltage, i.e. a dc voltage at thermodynamic equilibrium, on segments of nonuniform superconducting loop. A similar result was published early and was collaborated experimentally. The persistent power estimated by Berger is compared with the experimentally observed power. The attention of experimenters is drawn to the possibility to observe the persistent voltage thanks to its increase with the number of identical rings connected in series.
