Abstract:
1. A low resistance composite conductor using superconductors comprising: said low resistance composite conductor having a longitudinal direction, at least two superconductors, with each of said at least two superconductors having a longitudinal direction parallel to said longitudinal direction of said low resistance composite conductor and with each of said at least two superconductors having a preselected surface parallel to said longitudinal direction of said low resistance composite conductor, a normal conductor having a longitudinal direction parallel to said longitudinal direction of said low resistance composite conductor, said normal conductor having a preselected surface parallel to said longitudinal direction of said low resistance composite conductor, a connection of said preselected surface of each of said at least two superconductors to said preselected surface of said normal conductivity conductor, wherein said preselected surface of each of said at least two superconductors is electrically connected to said preselected surface of said normal conductor, wherein an electric current flows in said longitudinal direction of said low resistance composite conductor at a higher current density in said at least two superconductors than in said normal conductor at locations wherein said preselected surface of said at least two superconductors is electrically connected to said preselected surface of said normal conductor; wherein an apparent specific resistance of said composite conductor below a superconducting transition temperature of said superconductors is lower than a specific resistance of copper at the superconducting transition temperature.
