  1. The catch is critical current density(Amperes/cm^2). In the paper it is not provided properly, as only critical current is provided(Amperes). In normal superconductors critical current density is quite high, at least several thousands amperes per square centimeter. If their 250 milliampere current corresponds to even square millimeter, it is insanely low.
