Abstract

Electric discharges of several megawatts were applied, at 77 K, to propelling devices made of Y123 superconducting layers and thin insulating layers. During the discharges, the devices were strongly pushed in the direction opposed to the electron flow. The layered devices were apparently propelled by their emission of a momentum-bearing flux of an unknown nature. This flux weakly accelerated distant irradiated matter and created several physical effects not yet reported. The emitted beam had no electric charge, and traveled through materials without apparent absorption or dispersion, at a speed much greater than 1% the speed of light. The kinetic energy transferred by the propelling momentum of the devices to external masses, were proportional to the square of the electric energy of the discharges. No known effects were found which could explain these phenomena.
