  • Metallic glow discharge diode and triode devices with large cold cathode as efficient charge generator—a power cell
    Patent number: 11296620
    Abstract: The invention describes a metal container that comprises a cathode containing an insulated anode with gases at pressures less than a fraction (0.1-0.9) of a mmHg. Metallic normal glow discharge diode and triode devices with large cold cathode area as efficient charge generator to function as a power cell. A metallic glow discharge device comprising a cylindrical cathode and a coaxial insulated anode containing gas at very low pressure utilizing radial electric field. A metallic normal glow discharge diode device containing a planar geometry, with an insulated metallic plate parallel to the broad side of the container forms the anode, while the container acts as the cathode.
