Two spaced electrodes having a load in an external circuit connected between them are disposed in an electrically conductive liquid, and energy is imparted to the liquid in such manner that energized free electrons in the liquid excite free electrons which flow into one electrode to a greater degree than in the other electrode, thereby causing electric current to flow in the external circuit through the load
1. Field of Invention
The invention falls within the class of batteries, miscellaneous.
2. Prior Art
Acheson No. 375,243 discloses a thermo-electric generator wherein two spaced electrodes are disposed in a liquid and one electrode is directly heated, and the liquid is caused to flow so as to avoid accumulation of gases at the electrode surfaces. Free electrons in the metal of the heated electrode cause current to flow in an external circuit. However, unlike in the subject invention wherein free electrons are caused to flow from the liquid into one electrode more than the other, Acheson, by directly heating one electrode, causes free electrons to flow out of the heated electrode into the liquid and thus inhibit rather than enhance establishment of a current in the external circuit.
Case No. 344,345 discloses the heating of two spaced electrodes disposed in a liquid which, when heated, reacts chemically with one of the electrodes. The use of heat to promote chemical reaction is distinguished from the use of heat merely to impart energy to the free electrons in a conductive liquid, as is here involved.
Gilbert U.S. Pat. No. 1,379,909 discloses the heating of a bar, one end of which is drawn through a die. This results in a thermoelectric junction which produces measurable current in an external circuit. In contrast, the subject method does not utilize a junction.
The collection of electric current from an energized electrically conductive liquid in the absence of essential electrochemical change and in the absence of a thermoelectric junction was well-established by Lord Kelvin. Metal plates immersed in flowing sea water were used to create a magneto-hydrodynamic generator. Unlike the present subject invention, however, the metal plates were symmetrically perpendicular to the direction of flow and were carefully placed with respect to a magnetic field which differentially deflected electrons from the flowing stream.
By contrast, the subject invention eliminates the need for and does not employ a magnetic field. Further, among other differences, when the stream is flowing in this invention, the electrodes are assymmetrically oriented with respect to the source of energy.
Even though the metal plates immersed in salty sea water would appear to make a chemical "sea battery," Lord Kelvin's device was not a chemical battery. Lord Kelvin observed that such variables as placement of the magnetic field and the direction of water flow affected the current output of his device. Such variables do not affect battery operation.
Likewise, the electricity generated by the present subject invention is not due to electrochemical change and, as in Lord Kelvin's device, the variables which determine current output in the present subject invention do not determine current output in chemical batteries. Such factors as direction of flow of the electrically conductive liquid and orientation of the electrodes in the manner described do not determine the output of chemical batteries.
Scientific America, Apr. 23, 1910, p. 334, discloses a current generating device wherein electrodes are disposed on opposite sides of porous barrier which separates ions in liquid flowing through the barrier and, hence, a constant net free electron concentration is not maintained in the liquid.
"Geomagnetism" by Chapman and Bartels, Oxford University Press, 1946, pp. 445-448, and "Magnetohydronamic Power Generation, A Status Report, Electronics & Power", August, 1964 disclose spaced electrodes disposed in water which flows through the earth's magnetic field so as to induce an electrical current. The flowing sea water is the source of energy, but the ability of one electrode to respond to free electrons more than the other depends upon the magnetic field of the earth.
OBJECTS
The primary object of the invention is to provide a method for generating electricity, utilizing two solid electrodes of conductive material immersed in a conductive liquid, wherein energy is imparted to the liquid so as to agitate or excite free electrons therein, and to cause more of the free electrons to flow into one electrode than into the other. This may be accomplished by several modes, all emobdying the same basic concept.
A more specific object, relative to one mode of operation, is to provide for the disposition of two electrodes, having an external load circuit connected between them, in a stream of flowing conductive liquid, with one electrode upstream of the other, i.e., closer to the source of energy, whereby the upstream electrode is exposed to more free electrons in the liquid than the downstream electrode. More free electrons in the liquid reach the upstream electrode first. While variations in the amount of current flow in the external circuit may be obtained by making the upstream electrode the larger one, or by making it of greater electrical conductivity than the downstream one, measurable current, useful for operating low power devices, can be generated where the electrodes are of the same size, shape and material.
According to another mode, an object is to generate electric current by means of two electrodes immersed in a conductive liquid, wherein energy is imparted to the liquid by mechanically moving one electrode, i.e., by vibrating or oscillating it, thereby stimulating or moving more free electrons in the liquid in the vicinity of the moving electrode than in the vicinity of the other.
Still another object is to generate electrical current in a load circuit between two electrodes of different properties of electrical conductivity immersed in a conductive liquid, wherein energy is imparted to the liquid in the form of heat, and wherein more electron activity occurs in the electrode which is more electrically conductive.
These and other objects will be apparent from the following specification and drawings, in which:
FIG. 1 illustrates one mode of performing the method utilizing a flowing conductive liquid;
FIG. 2 illustrates a variation of the FIG. 1 mode;
FIG. 3 illustrates another mode of performing the method, wherein mechanical energy is imparted to the conductive liquid adjacent one electrode;
FIG. 4 illustrates still another mode of performing the method, wherein electrons are concentrated adjacent one electrode more than at the other electrode by means of heat applied to the conductive fluid; and,
FIG. 5 illustrates a variation of the FIG. 4 mode.
FIG. 6 illustrates still another embodiment in which the electrodes are of different metals.
Throughout the following examples, there are shown, in each instance, a conductive liquid 2, an external load circuit 4 having a milliammeter or microammeter 6. Polarity of the electrodes is as indicated.
Referring first to FIG. 1, electrodes 8 and 10 are supported in spaced relation to one another by an electrically insulating block 12. The electrodes were 1/4 inch in diameter and 5 inches long. Conductive liquid 2 is a stream of water supplied by a household water faucet, the water having sufficient impurities to render it conductive, and flows at the slowest rate possible consistent with a steady stream. Electrode 8 is upstream. Both electrodes 8 and 10 are of the same size and shape, and are immersed to a depth of about 1/2 inch in the water. Where electrode 8 was copper and electrode 10 carbon, the measured current in load circuit 4 was 17 microamperes. Where both electrodes were brass, the measured current in load circuit 4 was 25 microamperes. Where electrode 8 was aluminum and electrode 10 brass, the measured current in load circuit 4 was 43 microamperes.
In the FIG. 2 example, electrodes 8a and 10a were both constructed of shredded aluminum foil and disposed in a rubber hose 14 connected to a domestic cold water faucet 16. In this case the measured current in external load circuit 4 was 30 microamperes.
In the FIG. 3 example, electrodes 8b and 10b were of the same size and shape as electrodes 8 and 10 of the FIG. 1 example, both were made of brass, and both were immersed in the conductive liquid 2, which was cold tap water, to a depth of about 1/2 inch. Electrodes 8b and 10b were individually supported by electrically insulating blocks 12a and 12b. Electrode 10b was held stationary in the conductive liquid, which also was still, and electrode 8b was set into vibratory motion at the rate of four cycles per second by means of a solenoid 18. This yielded 14 microamperes in the external load circuit 4. No current was produced when both electrodes were motionless.
In the FIG. 4 example, electrodes 8c and 10c were of the same size and diameter as in FIGS. 1 and 3, and supported by an electrically insulating cover 12c to an immersion depth of about three inches in conductive liquid 2, which was tap water contained in a vessel 20. In this case the liquid was heated by an external source of heat 22 to approximately 200 DEG F. When electrode 8c was aluminum and electrode 10c was brass, the current flow in external load circuit 4 was 1.4 milliamperes. When both electrodes were of brass, no current was produced.
FIG. 5 illustrates a practical modification of the FIG. 4 example. Here, sets of electrodes 8d and electrodes 10d were made of 20 gauge sheet metal 31/2 inches long and 1 inch wide, the sets of electrodes interdigitating with one another and being supported on common conductors in a vessel 20a, the common conductors being supported by an electrically insulating block 12d. The conductive liquid was tap water, as in the previous examples, and was heated to about 200 DEG F. by a source of external heat, not shown. The same effect can be achieved by imparting the same amount of energy to the water by other means as agitation. Electrodes 8d were of aluminum and electrode 10d were of brass. The current yield in external load circuit was 60 milliamperes, which was more than enough to operate a seven transistor radio at full volume.
In the FIG. 6 example, electrodes 8e and 10e were made of aluminum and brass, respectively, each of the same size and shape as in the examples of FIGS. 1, 3 and 4. The electrodes were mechanically supported by insulating stoppers 12e in a glass tube 20b which was 1/2 inch in diameter and 31/2 inches long. The conductive liquid 2 was tap water, at room temperature, about 73 DEG F. The current yield in external load circuit was 20 microamperes. When the water was replaced by an electrically conductive jelly (i.e., gelatin), the device continued to operate and produce 15 microamperes in external load circuit 4.
In all embodiments, one of two electrodes, disposed in a conductive liquid to which energy is imparted so as to excite free electrons therein, is made to respond to more free electrons than the other one, either by locating closer to the source of energy or by virtue of the fact that it is made of more electrically conductive material, or because it is agitated so as to contact more free electrons than the other.
In all examples, the net free electron concentration, i.e., free electron population in the conductive fluid, is maintained substantially constant, as contrasted with batteries relying upon significant electrochemical change between the electrodes. Also, in all examples, the flow path for electrons and liquid between the electrodes is substantially free.
Because electrochemical change is not essential to the operation of this invention, the elements of this invention do not degenerate and decompose into waste products. Consequently, there is not particulate or chemical pollution of the electrically conductive liquid.
Furthermore, since a magnetic field is not essential to the operation of the apparatus or method, the orientation of the electrodes with respect to the earth's magnetic field is of no consequence.
