    "abstract": "We critically review our recent claims that it is possible to obtain a\npropellantless propulsion device similar to electrodynamic tethers by means of\na closed wire partially shielded by a superconductor from the outer magnetic\nfield. We find that such a device is not possible as it violates basic physical\nlaws. Furthermore, we show what is the correct local picture for the currents\ndistribution within the superconductor.",
