Description

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. The metallic container provides for basic normal glow discharge devices. Even though gas molecules are continuously moving following Brownian motion, since they are neutral the gases don't carry electrical current. If an electron is generated by cosmic rays or the photoelectric effect at this low pressure of the confined gas, the electron will have a mean free path of approximately a cm or so. Under the action of an electric field, the electron will gain sufficient energy to ionize further neutral gas molecules. Creating an electron and an ion pair, which under the influence of the electric field will further ionize the gas. In gaseous discharge ionization, recombination and meta-stable states occurs generating photons when the excited ions returns to the neutral state which trigger photo-electrons from a cathode. This process generates electrons, ions and neutral molecules continuously. The low pressure of the gas and the low mass electrons migrate towards the anode rapidly, while the heavier positively charged ions migrate towards the cathode slowly. By virtue of this a plasma of electrons and ions surrounds the anode. This is a typical characteristic of “normal glow” discharge. A glow discharge is considered to be “normal” until the glow covers the whole cathode area.





BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1b. A characteristic circuit configuration, wherein a DC bias supply source, a series resistor, which controls the current and the diode device connected to an external load.



FIG. 2. Radial Field Configuration of the cold cathode metal “normal glow” discharge device. A cylindrical cathode and a coaxial insulated anode containing gas at very low pressure. The distance between the anode and cathode illustrated is 3 cm. Therefore, the diameter of the cylinder would be about 6 cm. The length of the cylinder and anode is variable and depends on the load current requirement.

DETAILED DESCRIPTION


FIG. 1 shows the characteristic circuit configuration of such devices. A DC bias supply source, a series resistor which controls the current and the diode device. The larger the cathode area the larger the plasma with an increased number of ions and electrons surrounding the anode. A small fraction of these charged particles are required to sustain the glow discharge phenomenon, while the rest of the charged particles which are generated due to the electrical field working on gas molecules are available to drive an external load and not draining any additional current from the bias supply. The ratio of sustaining glow discharge current to the current supplied to load could be as high as 10 times.


Two (2) configurations for making such devices are disclosed by FIGS. 2 and 3. A cylindrical cathode and a coaxial insulated anode containing gas at very low pressure utilizing radial electric field approximately 1 meter in length. The “normal glow” discharge phenomenon occurs at voltages which are multiples of the first ionization potential of the gas mixture. That can be between 70-300 volts depending upon the geometry and the nature of the gas. The other configuration is planar. Where normal electric field will be effective. The anode is an insulated metal plate parallel to the broadside of the container. The container acts as the cathode. In both configurations the distance between the anode and cathode can be but not limited to approximately 3-4 cm. Therefore the diameter of the cylinder would be about 6-8 cm. The height of the planar box would be approximately 6-8 cm. In the cylindrical configuration a practical length would be approximately 1 m. For the planar configuration the area can be 1 sq meter or greater on the broadside.


This invention of generating a power cell opens opportunity for small or large scale electrical efficient power generation. The concept is very simple to execute and would provide units at very low costs as well as non-polluting. Since the gas is at very low pressures the structural strength of the units would be very light and there would be low chance of leakage of the gas. The small scale application one could use both in developed as well as developing countries for charging lithium ion or NiCAD batteries. The batteries in a series configuration are charged. The charged cells operating at low voltage (3.2 V) could operate light emitting diode devices efficiently and further a new concept of home wiring could be used at low DC voltage.
