(20) Turning now to the figures:

(21) FIG. 1 symbolically shows the compartments used to analyze an electrochemical reactor. FIG. 1 gives organization to the different parts of a simple reactor referred to in this disclosure. It is not meant to be physically realistic with respect to size. The cathode is dissected into four regions. Three compartments are shown within the metal itself. The flow of deuterons is shown by arrows. The label 1 represents the metallic cathode, usually palladium in the preferred configuration. The labels 2 and 3 represents compartments 2, and 3 respectively, which are discussed in detail below. The label 7 represents the anode which in the preferred embodiment is composed of palladium.

(22) The label 6 represents the solution consisting in the preferred embodiment of a gel containing antidesiccant, in combination with LiOD, palladium salts, and heavy water (D.sub.20). The power supply and control unit consists of a current source and FUSOR reactor control device as described in Swartz (1989), and are not shown in the figure. For simplicity, the electrical connections, heat removing apparatus, and several improvements described in this disclosure are not shown in FIG. 1.

(23) The application of said power source creates an applied electric field intensity which produces cation flow towards the cathode. There results in the near cathode solution (labeled as 5 in FIG. 1) a buildup of deuterons, and a low dielectric constant (gas bubble) layer. The bubbles are labeled as number 10 in FIG. 1. There may be spikes or on the cathode (labeled as 11 in FIG. 1).

(24) Classically, an electrode in a deuteron solution at equilibrium should measure potentials associated with the Nernst equation. However, during the reaction, the system is not at equilibrium. Thermodynamics assumes equilibrium but tells nothing of the rate. Therefore, a quasi-1-dimensional model can be used to describe the situation external to the cathode. In the absence of solution convection, molecular flux (F) results from both concentration gradients and electrophoretic drift.

(25) $F\left(D^{+}\right)=-\left[B.Math.\frac{d\left[D^{+}\right]}{dz}\right]-\left[.Math.\left[D^{+}\right].Math..fwdarw.\stackrel{.fwdarw.}{}\right]$

(26) Coupled equations thus determine the distribution of deuteron species in the bulk solution. K.sub.f is the bulk rate of the desired reactions. K.sub.c is the rate at which deuterons physically enter the palladium cathode. B is the diffusivity.

(27) $\frac{\underset{\_}{d}\left[D^{+}\right]}{\underset{\_}{\mathrm{dt}}}=-K_F+\left[B.Math.\frac{d\left[D^{+}\right]}{\mathrm{dz}}\right]+.Math.\left[.Math.\left[D^{+}\right].Math.\left(\stackrel{.fwdarw.}{}\right)\right]+.Math.\frac{d\left[\right]}{\mathrm{dz}}.Math.\frac{d\left[D^{}\right]}{\mathrm{dz}}]-K_c$

(28) For simplicity, a number of approximations are made, such as no free charge density. In addition, deuteron penetration occurs at the cathode, and is electron limited, at an efficiency of Ec, so that the following steady state expression for the initial coefficient of the final spatial distribution of deuterons is:

(29) $D^{+}\left(z\right)=\frac{\left(\frac{I.Math.E_C}{A.Math.F}\right).Math.\sqrt{\frac{K_F}{B}}}{\cosh \left(\sqrt{\frac{K_F}{B}}.Math.L\right)-1}$

(30) FIG. 2 a simplified two-dimensional diagram which schematically shows the cathodic compartments used to describe a CAM electrochemical reactor. The cathode is dissected into several regions. The label 1 again represents the crystalline metal cathode. In FIG. 2, the label 2 points out the entrapped volumes within compartment 1 (label 1). Three of the compartments are open to the ambient and two are labelled by number 3; they represent compartment 3. Most current theories involve the crystalline metal (label 1).

(31) One problem with tunneling in the crystalline metal is that the internuclear separation is even larger (0.3 Angstroms) than in an isolated D.sub.2 molecule. Although this may be offset by theoretical screening by localized 4d electrons, the tunneling probability remains vanishingly small until internuclear distances of less than 0.7 Angstroms occur.

(32) Therefore, to explain the invoked tunneling, current theories suggest either screening effects of electrons, high effective mass electrons, decreased effective deuteron mass, deuteron energy fluctuations, or coherent screening. The rest of theories use the periodic lattice to surmount the obstacle. Other models involve shrunken atoms either by a theory or by the proven interaction of heavy negative particle with the crystalline metal lattice containing deuterons. The muon capture theory begins with heavy muon capture by a deuteron leading to a greatly contracted electronic shell around the deuterium nucleus by a factor of 200.

(33) The catastrophic active medium (CAM) theory differs from the other theories in that the desired reactions are hypothesized to not occur within the metal bulk, but at certain large vacancies and defects by the sudden fractional desaturation of deuterons. The CAM Model approximates the palladium (or titanium) used by three compartments. FIG. 2 schematically shows a piece of such highly loaded metal. The bulk metal crystalline lattice comprising the cathode is compartment 1. Large defects consisting of enclosed spacesnot open to the ambientcompromise compartment 2. With subsequent crack, fissure, or other dislocation compartment 3 is formed. The model for the cathode consists of three compartments (FIG. 1).

(34) One cathodic compartment consists of the crystalline (e.g., beta phase) palladium into which deuterons can diffuse and remain in well-defined shallow energy traps. The second and third compartments of the cathode consist of the defects, grain boundary dislocations, and larger defects merging into bubbles and fissures. It is the multiple compartments of the cathode which makes the CAM theory unique. The desired reactions are postulated to occur outside of the crystalline palladium lattice (compartment 1). It is the movement of deuterons to compartment 2 which begins the process at that location. Catastrophic deuteron flux, coupled with a exothermic deuteron desaturation of the active medium, drives the fusion reactions.

(35) This occurs until, by a second catastrophic process, the fusion-defect-site is no longer confined. The final reactions in the CAM theory ends with the opening up of the defect or fissure through a large crack (compartment 3). By this theory the fissures are the result of the catastrophic desaturation of the active medium that was previously fully deuterated (e.g. in the preferred embodiment palladium or titanium).

(36) The CAM theory may offer explanations for the tremendous difficulties observed by many experimenters attempting to repeat experiments, for the bursts of excess energy seen, for the very tardive appearances of both the excess energy and those bursts. The CAM theory begins at the cathode, labeled 1, by taking into account the special character of palladium and titanium with respect to deuterons and hydrogen.

(37) In most metals (e.g. aluminum, cobalt, copper, iron, nickel, platinum, silver, and tin) the deuterium solubility is described by the experimental relation [where K is the Sievert constant, and p is the partial pressure of deuterium gas (S=K*{square root over (p)})]. However, all such metals have low solubility, and only dilute solutions are stable (about one deuterons per 10,000 or more metal atoms). Furthermore, in such metals deuteron solubility is endothermic. Therefore, the solubility for these metals increases with temperature.

(38) In contrast within palladium and titanium (and other Group IVb and Vb metals and some rare earths such as cerium, lanthanum, niobium, tantalum, thorium, vanadium, zirconium) much different behavior occurs. First, much more concentrated solutions can exist. For these metals the greater deuteron concentrations mean that they act like emphores (vases, similar to the biomaterial myoglobin). Furthermore, the deuteron binding in these metals is exothermic. This indicates that the deuterons reside in shallow energy traps located within and throughout the lattice. Most importantly for the CAM theory, the deuteron binding capacities decrease with temperature for these metals.

(39) The deuteron-laden metal lattices change significantly with increasing deuteron loading. An extensive literature, involving solubility isotherms and x-ray results demonstrates two solid solutions of protons in palladium. During the time of deuteron loading there is progressive increase in the volume of the cathode. A 5000 atmosphere internal pressure is consistent with the 4% plastic deformation following deuterium loading.

(40) Classically, the atomic ratio of deuterons to palladium is used to describe the quantity of deuterons in metal.

(41) (Pd D.sub.x), where

(42) $x=\frac{\left[num\mathrm{ber}D\right]}{\left[num\mathrm{ber}\mathrm{Pd}\right]}$

(43) This is broken up in the CAM model. The total deuteron content in a given volume of palladium cathode is modeled as the sum of the deuterons physically located in compartments 2 and 3 (and in any amorphous palladium hereinafter ignored for simplification) and those deuterons which are entrapped within the palladium lattice (compartment 1). The quantity of the former amount is modeled as the product of the Henry gas solubility coefficient and the deuterium partial pressure [P.sub.D.sub.2].

(44) The quantity of the latter depends both upon the amount of deuteron binding material present [e.g. palladium in its beta phase], the number of intralattice sites available for the deuterons (n) and the affinity of the palladium lattice for those deuterons.

(45) The affinity is thus modeled as a fractional saturation (y.sub.D).
P.sub.D.sub.2=[a.Math.(P.sub.D.sub.2).Math.f]+[(1f).Math.y.sub.D.Math.{circumflex over (n)}]

(46) f is the fractional amount of defect sites (e.g. compartments 2 and 3) in the beta-phase palladium. For a solid metal cathode, the quantity of dissolved deuterons in compartments 2 and 3 (first term above) is small compared to that bound to palladium because most of the metal resides in a crystalline lattice. Thus, f is therefore close to zero.

(47) This relation can be examined in the limit of f approaching zero by l'Hospital's Rule. That analysis indicates that the deuteron pressure is related to the quantity of bound deuterons as:
Lim P.sub.D2(f=>0)=n*y.sub.DI

(48) This indicates that CAM model in that limit is consistent with well-known solubility laws of deuterons in most materials.

(49) FIG. 3 shows the hydrogen-solubility (hereinafter called saturation or binding) for palladium as a function of temperature, along with Taylor series expansions at two temperatures. The curve shows the quantity in cubic centimeters (STP) contained in 100 grams of palladium. The total quantity of hydrogen in palladium is markedly temperature dependent. The Taylor series expansion shows that the differential desaturation with temperature increases with decreasing temperature. The sharp decrease in total quantity bound for an increase in temperature may drive the desired reactions by catastrophically displacing deuterons into compartment 2.

(50) Many of the technologies now described are useful no matter how filling of the deuterated metal occurs. Some preliminary comments are in order. Because the process and apparatus are independent of method of filling said metal, a greater examination is now given to said deuterated metal. The actual loading of the palladium will be ignored for the CAM model and theory, but said deuteron loading does play a significant part of the device described below.

(51) The CAM theory considers palladium as an active medium because unlike most other metals, palladium has a deuteron capacity which falls rapidly as the temperature rises. The temperature effect upon deuteron desaturation, in palladium, usually begins in the beta phase. The binding decreases so markedly with temperature that there is almost a decade decrease from just 0 to 50 Centigrade. At 110 C, the beta phase converts to the alpha phase with an additional 0.3 moles of 0.sub.2 gas released.

(52) In the CAM model there is assumed to be rapid mass transfer from compartment 1 to 2 as the catastrophic desaturation occurs. This is a reasonable assumption because of the deuteron diffusivity in palladium increases with temperature. It is that increase in diffusivity which enables palladium foils to remove hydrogen and deuterium from other gases at elevated temperature. The CAM hypothesis was tested in a computer simulation wherein the desired reactions were hypothesized to occur only in the metal-surrounded free gas compartment located physically within the cathode (FIG. 1). The fractional saturation was approximated by expressions for both pressure and temperature qualitatively similar to those reported.

(53) $y_D=1-\exp \left[\frac{-P_{D_2}}{c_1.Math.T}\right]$

(54) The last qualitative assumption used was that the temperature would increase very slightly with the desired events, secondary to markedly increased pressures for deuteron pressures greater than 50 atmospheres.

(55) The qualitative model used to test the catastrophic active medium (CAM) theory did show that in the model the metal was capable of exothermic catastrophic fractional desaturation. FIG. 6 shows the results of that simulation. The same phenomenon occurred for several different such qualitative formulations. The three curves are A) the normalized deuteron pressure (in atmospheres), B) the normalized system temperature, C) the fractional saturation (y.sub.D) of the active medium (palladium).

(56) FIG. 4 shows that as current is delivered to the cathode there is a steady increase in deuterium within the cathode. Initially, because of the large capacity for deuteron binding in compartment 1, the deuteron pressure rises only slightly. Thus the sublinear relation of total deuteron content to pressure, shown by the CAM model may also be consistent with the {square root over (p)} law, experimentally derived, and discussed above. FIG. 4 shows that the computer model predicted that compartment 2 is suddenly, catastrophically, fed deuterons from the larger crystalline palladium lattice compartment. It can be seen that there occurs a critical catastrophic event wherein the fractional saturation suddenly falls as the temperature rises in concert.

(57) As the active medium (palladium) catastrophically releases deuterons to the defect sites astronomic pressures develop. In a crescendo fashion, the desired reactions result and the cathodic temperature rises even further. The temperature in compartment 2 rises further, but is limited as phonons carry off the excess energy of the reactions. The active medium around the defect site, in which the desired reactions occur, reabsorbs phonons resulting in the observed excess heat.

(58) The catastrophe occurs precisely because the further temperature increase causes even more flux of deuterons into compartment 2, further increasing the likelihood of the desired reactions. The reaction is driven by the catastrophic fractional desaturation of deuterons from the crystalline palladium lattice, previously filled to capacity. The catastrophic mass transfer of deuterons to the defects (from the saturated metal, not the solution) enables the desired reactions to occur. Also the electrical charging of the cathode to a high negative voltage should enhance the reaction.

(59) The reactions of deuterium continue until the crystalline palladium (the active medium because of its high fractional saturation and its exothermic desaturation tendency) is spent of its deuterons or until, by a second catastrophic process, the fusion-defect-site is no longer confined. At that point, catastrophic exposure of compartment 2 to the ambient occurs creating compartment 3. The intracathodic compartment 3 of the CAM theory is known from endstage deuteron (or hydrogen) embrittlement. This compartment usually declares itself when the dissolved deuterons, after entering a metal through a corrosion reaction or by cathodic polarization, explode into the ambient as the metal fissures or otherwise irrefutably changes shape. The fugacities involved are enormous ranging from 5000 up to an estimated 107 atmospheres for hydrogenated palladium.

(60) One special compartment 2 should be noted. Because the solubility of deuterium in water is relatively low, the electrolyte solution itself acts as a barrier to create another type of compartment 2 which is more compliant because of the water (hydrogen bonds vs. covalent bonds of the palladium). The space charge formation, the low dielectric layers (gases) in front of the cathode, any spikes on the cathode, work together at this compartment 2 to create very large electric field intensities. Further ionization reactions contribute to activate the reaction.

(61) Turning now to FIG. 5 shows a typical experimental setup, but with a novel cruciform-shaped sacrificial anode of palladium in a solution (labeled 7). The preferred solution (6) contains palladium salts, lithium deuteroxide, and heavy water. The cruciform shape is the preferred shape of the anode in that as it is sacrificed to the solution (enabling efficient codeposition of palladium and deuterons) the surface area most nearly remains constant during its decomposition of said sacrificial anode. The connections to the electrodes are labeled as 81 and 82. The reaction vessel is labeled 8. The cathode is labeled as number 1.

(62) This type of system, coupled with the FUSOR (JET ENERY, INC., MA) drive system, is capable of filling the cathode with deuterium from the solution. However, the deuterated metals could also be filled by codeposition of deuterium and palladium, or by high pressure deuterium gas.

(63) In the following devices, heat pipes are included as well as a superassembly capable of removing excess heat.

(64) In the following devices, palladium is the described preferred embodiment for the cathodes, but members of the group consisting of vanadium tantalum, niobium, lanthanum and cerium may also be used.

(65) Furthermore, one improvement is that the cathode should be improved for deuteron solubility, while being stabilized from catastrophic deformation which would end the desired reactions. There are a number of methods by which this is accomplished.

(66) Within the metal (labeled 1), there are several methods used in this device to minimizing catastrophic fracture. First, is the preferred use of cathodic binary alloys. Some palladium alloys (e.g. boron, silver or gold) exhibit, for intermediate compositions, peak levels of hydrogen (and deuteron) solubility.

(67) Second, in the preferred embodiment manganese could be added to the palladium to decrease the susceptibility to deuteron cracking. Third, in the preferred embodiment said cathode is stabilized by an external barrier construction. Fourth in the preferred embodiment additional diffusion barriers are placed to obstruct the released deuterons.

(68) In the preferred embodiment internal materials are added to decrease the likelihood of electrode deformation. For example a composite material could be fashioned using palladium and epoxy so that the electrode is more like bubblegum than like crystalline metal. Although the inter- and intramolecular forces are less, the bond energies increase because the important parameter is the product of force times distance. The weaker interactions, acting over longer distances, would lead to increased energies required to rupture the electrode.

(69) In the preferred embodiment tungsten microspheres are added to the metal. The very large melting temperature of the tungsten prevents it from melting and alloying with the palladium when the desired reactions are achieved. The purpose of the spherical shape of the microspheres is to stop the propagation of defects by giving a large radius of curvature which thus decreases the likelihood of said defects proceeding.

(70) FIG. 6 a simplified two-dimensional diagram which schematically shows the effect of providing intracathodic materials to quench mechanical crack propagation and subsequent breakdown of said cathode. The crystalline metal cathode is labeled 1. The deuterons and D2 gas located therein are not labeled. Compartment 2 is labeled, and a compartment 3 (compartment 2 opening to the ambient) in the upper right corner is not labeled.

(71) Spheres, or rods, labeled 30 in FIG. 6, are present within the cathode to act as defect terminators which stop propagating defects. Their radius of curvature is such that the force applied to the metal lattice is minimized.

(72) After turning to FIG. 6, attention is drawn to the barrier labeled 40 which surrounds one sphere of compartment 2 (which is not labeled). It is made of a material characterized by a high modulus of elasticity so as to retard any expansion of compartment 2. The purpose of the expansion barrier is to prevent expansion of the cathode (labeled 1) and thereby minimize formation, and propagation of compartments 3.

(73) FIG. 7 is an isometric drawing of a CAM electrochemical device, and shows the direction of the electric field. FIG. 7 shows a see-through view over the cathodic volume. This cutaway exposes the four concentric components of the device at that location. In this simplified CAM device, surrounding the cathode, in coaxial fashion, are a deuteron diffusion barrier (labeled 50) and an expansion barrier (labeled 40). These barriers are discussed in detail below. In this particular device, the cathode is axially-fed the deuterons. For simplicity, the power supply, control apparatus (including phonon drive, magnetic fields, thermal capture system and electrical connections) are not shown in FIG. 7.

(74) The electric field points from anode (labeled as 7) to the cathode (labeled as 1). In the device shown in FIG. 3, label 20 represents the structural casing wall which makes this CAM device dry. The enclosed solution, in the preferred embodiment actually consisting of a heavy water-LiOD-gel, and is labeled number 6. The device is shaped like a fuse and can be easily placed into, or removed from, an assembly and system used to both power the reaction and extract the excess heat. For simplicity, the power source, connections, and thermal extraction system are not shown.

(75) FIG. 8 shows a vertical cross-sectional slice of a CAM device, having a external structural casing support system, a centrally placed axially-filled cathode, a coaxial deuteron-barrier and coaxial expansion-barrier. The structural support system (labeled 20) encloses an axially-filled cathode for loading reactions consisting of a coaxial deuteron-barrier and coaxial expansion-barrier. The expansion barrier (labeled 40) surrounds the cathode and prevents expansion. Between the two is a deuteron impermeable barrier (labeled 50) which prevents outward diffusion of deuterons when the cathode is catastrophically desaturated of its deuterons. The barrier prevents loss of deuterons to the expansion barrier, and acts as a circumferential locus of fusion. The cathode is labeled as 1. In this CAM device, the cathode is charged in a direction perpendicular to the drawing (e.g. similar to FIG. 7). For simplicity, the power supply, FUSOR control apparatus including phonon drive, magnetic fields, thermal capture system and electrical connections are not shown in FIG. 8.

(76) FIG. 9 is a cluster of seven CAM devices held together by an external structural casing support system, and an intercluster thermomechanical material. A high thermally conductive epoxy would be the preferred embodiment. This would enable facile, relatively inexpensive, support and thermal coupling for the system.

(77) The cathodes are fashioned as cylindrical palladium surrounded by a deuteron impermeable (or relatively impermeable) barrier (e.g. tungsten or gold). The result would be that after a slow charge with deuterons, the catastrophic desaturation yields a rapid symmetric flux through the walls of the cathode cylinders-directly into the impermeable wall thereby increasing fusion. For simplicity, the power supply, FUSOR control apparatus including phonon drive, magnetic fields, thermal capture system and electrical connections arc not shown in FIG. 9.

(78) FIG. 10 shows a vertical cross-sectional slice of a CAM device, with a central axially-filled cathode, two coaxial deuteron-barriers and an inner thermal pipe. This device is surrounded by a structural support system labeled 20. The axially-filled cathode (labeled 1) is constructed within and around novel devices. Coaxial with the cathode are two sites consisting of double coaxial deuteron-barriers and an inner thermal pipe.

(79) The inner thermal barrier is labeled 70. In the preferred embodiment this would be gold. Within that barrier is the thermal pipe (labeled 70). In the preferred embodiment, the pipe could consist of a thermocouple, or be connected to a themocouple by a diamond filament or thermally conductive composite material. The outer deuteron barrier is labeled 50. The barrier to expansion is labeled 20. For this device the inner four layers (from inner to outer) are diamond filament, gold, palladium, and gold.

(80) FIG. 11 shows a vertical cross-sectional slice through a novel CAM coaxial device with a coaxially-filled cathode, and an inner coaxial deuteron-barrier and thermal pipe. This embodiment is in a cylindrical configuration. The electric fields are in the radial direction. This device is characterized by coaxial loading of the cathode with deuterons (labeled 1).

(81) In the figure, the anode is circumferential to the cathode, and is labeled as 7. The solution (labeled 6) consists of lithium deuteroxide, palladium deuteroxide, and heavy water as the preferred embodiment. The inner diffusion barrier (labeled 60, and consisting of gold in the preferred embodiment) and the inner thermal pipe (labeled 70, and consisting of a diamond filament in the preferred embodiment) are shown in cross-section. For simplicity, the power supply, FUSOR control apparatus including phonon drive, magnetic fields, thermal capture system and electrical connections are not shown in FIG. 11.

(82) Also, the intracathodic defect-terminators and the fenestrated extra-cathodic expansion barriers are not shown. The heat energy is extracted from the center. In this CAM device, the activation current is supplied between 1 and 7. The barrier (70) acts to provide a geometric focus at which the desired reactions occur. The is extracted through thermal pipe (70) which in the preferred embodiment is diamond, or composites of diamond (e.g. thermally conductive epoxy filled with diamonds).

(83) FIG. 12 shows three CAM devices (labeled as 90 in FIG. 12; but similar to what is shown in FIG. 3). These devices each contain a cathode (labeled 1), intradevice gel containing lithium and palladium deuteroxide (labeled 6), and anode (labeled 7). These CAM devices are inserted, similar to a fuse onto a holding board (labeled 91), held in place by clips (labeled 92). Some of the clips are electrically conductive (e.g. to hold the anode) whereas other clips are insulators.

(84) After being mounted to the board, the three CAM devices are inserted into the device receptor apparatus (labeled 93 in FIG. 12). Said apparatus has electrical and thermal connectors (labeled 96, and 97 respectively) which are held in a mechanical connecting system (labeled 94). The entire apparatus has heat dissipative radiator (labeled 95).

(85) The purpose of the device receptor apparatus is to integrate the three (or more) CAM units. The three cathodic connectors are connected to the control apparatus. However, the thermal connections (labeled 97) are used to couple said units together. The damage or rundown of one CAM unit is thus easily exchangeable by replacement with a functioning one.

(86) FIG. 13 is a crossectional drawing of a lamellar CAM reactor. This device has two orthogonal applied electric fields. The first (labeled E-field number 1 in the figure) is that which is applied to charge the palladium with deuterons. The second applied electric field intensity is delivered after full charging has been achieved. In the figure the anode and cathode are labeled as 7 and 1. The electrolyte solution or gel is labeled as 6. The connections for the first electric field are labeled as 81 and 82. The connections for the second electric field are labeled as 85 and 86. The mechanical casing is labeled 20. The deuteron impermeable barrier is comb-shaped in this preferred configuration, and is labeled 55 in FIG. 13. The cathode in this preferred configuration is divided into parallel slabs. Between these slabs alternate deuteron-impermeable barriers. Application of the second electric field causes the deuterons already loaded in the cathode to redistribute, but the deuteron-impermeable barrier(s) act to enhance the desired reactions.

(87) The 4-terminal CAM device shown in FIG. 13 does not show, for simplicity, the thermal transfer equipment or these parts needed for superassembly as described above.

(88) Turning to FIG. 14 which shows three lamellar CAM reactors. Each device is equipped with orthogonal applied electric fields. The second applied electric field intensity is delivered after full charging. Each reactor is labeled as 90 in FIG. 14, but similar to what is shown in FIG. 13. These devices each contain a cathodes (labeled 1), intradevice gel containing lithium and palladium deuteroxide (labeled 6), and anode (labeled 7). These CAM devices are inserted, similar to a fuse onto a holding board (not shown), held in place by clips (labeled 102). The three CAM device are shown connected to a microprocessor control system (labeled 110). Said apparatus has an electrical bus to connect the anodes (labeled 105) which are connected to the anodic connectors (labeled 82). Said apparatus has an electrical bus to connect the cathodes (labeled 106 and 107) which are connected to the cathodic connectors (not labeled in the figure). The cathodic system buses (106 and 107) are electrically shorted together during the deuterium charging.

(89) Said apparatus has a thermal bus (labeled 107) connected to the heat pipes (labeled 70) which are held in a mechanical connecting system (labeled 20). The entire apparatus has a heat dissipative system which is not shown.

(90) The purpose of the receptor apparatus is first to integrate the three (or more) CAM units. The three cathodic connectors are connected to the control apparatus. However, after loading the cathodes, the cathodic buses (106 and 107) are separated and a second electric potential is supplied between these two buses. The result is the second applied electric field which is shown in FIG. 13, but not in FIG. 14. The result is the piling up of deuterium at the deuteron-impermeable barriers (labeled 55 in FIG. 14). The energy is directed out via the heat pipes (70) and the thermal bus (107). The damage or rundown of one CAM unit is thus easily exchanged by replacement with a functional one.

(91) FIG. 15 is a crossectional drawing of a device used to activate a CAM reactor. The cathode is labeled 1. The solution or gel is labeled as 6. The mechanical casing is labeled 20. The deuteron impermeable barrier is labeled 55. In the figure the anode and the solution are not shown, because the cathode is axially loaded. The CAM device shown in FIG. 15 does not show, for simplicity, the thermal transfer equipment. External structures labeled 110 and 120 are near circumferential in location to the casing (20), and are used to squeeze the CAM reactor. The resultant pressure causes catastrophic desaturation. Also not shown in the figure are temperature control systems which can also activate the reaction.

(92) Turning to FIG. 16, shown are three pressure-activated CAM reactors. Each reactor (un-labelled) is similar to that shown in FIG. 13. These devices each contain a cathode (labeled 1), heat pipes (labeled 70), expansion barrier (40), deuteron diffusion barrier (labeled 50), external casing (20), and thermomechanical connector (labeled 130) for assembling the heat pipes (70) to the external thermal bus (140). The entire apparatus has a heat dissipative system which is not shown. Said apparatus has an electrical bus to connect the anodes (not shown), and an electrical bus to connect the cathodes (not shown). The CAM devices are inserted, similar to a fuse onto a holding board (150, 151 above and below the assembly), held in place by clips (not shown for simplicity). External structures labeled 110 and 120 are near-circumferential in location to the casing (20), and are used to squeeze the CAM reactor.

(93) The resultant pressure causes catastrophic desaturation. The purpose of the receptor apparatus is to integrate the three (or more) CAM units, and to couple said devices to the control system. As before, damage or rundown of one CAM unit allows easy replacement by a functioning one.

(94) FIG. 17 is another configuration of device which can be easily integrated into power and heat systems. It consists of a reactor as described above (cf. FIG. 13) which is arranged as a thick film device, located in a transistor-like header. The header (labeled as 200) is perforated by six (6) holes (not labeled) to accommodate insulators (labeled 210), through which six leads enter said header. The leads consist of electric leads (182, 185, 181, and 186), and two thermal connections (labeled 170 in FIG. 17). The electrical leads are connected to the thick film device. The anode (labeled 7) is connected to the anodic terminal (82) to which is bonded the anodic lead (labeled 182).

(95) The cathode (unlabelled but located adjacent to its cathodic terminal labeled 81) is connected via the cathodic terminal (81) to the cathodic lead (181). The electrolyte is an electrolyte gel as discussed above (labeled 6). After loading the leads 185 and 186 are activated to drive the deuterons into the obstructing barriers (which alternate with the cathode). Thermal leads 170 are, for simplicity, not shown connected to the thermal bus which extracts the heat from the reactor.

(96) FIG. 18 shows a CAM reactor with a modification to extract an isotopic nuclear fusion product (e.g. tritium) from said reactor rather than heat. The device shown in the figure has an axially loaded cathode (labeled 1). The anode is labeled 7, and the solution 6. The structural casing is labeled 20. The cathode and anode have electrical connections labeled 81, and 82, respectively.

(97) The electrical connections to the FUSOR power supply are labeled 181 and 182. An expansion barrier (40) is shown.

(98) An inhomogenous magnetic field intensity is applied by coil labeled 300 to one portion of the cathode (1). Said magnetic field is driven by the power supply (labeled 301) in the figure. The spatially inhomogenous magnetic field could also be created by a superconductor.

(99) The cathode is loaded by the electrochemical drive system. The differential magnetic susceptibility between isotopic fuel and the nuclear fusion product is used to magnetically pump the product to and through the barrier labeled 350. At that location there is a buildup of the isotope with the larger magnetic susceptibility due to said differential magnetic susceptibility. The magnetic force resulting from the applied magnetic field is the derivative of the magnetic coenergy with respect to distance in the axial direction, and is proportional to the square of the current, the square of the number of turns in the coil (300), and said differential magnetic susceptibility.

(100) The products are removed at the product barrier (labeled 350). If said isotopic product is of lower magnetic susceptibility, then the coil is moved toward the portion of the cathode near to the solution (6).

(101) A two-stage method which involves a first stage of loading, and then, a second stage of sudden rapid (catastrophic) flow of hydrogen within the metal.

(102) An apparatus including a novel cathode, novel anode, and heat pipes, to improve reaction rates. An apparatus including means to extract products. An apparatus including intraelectrode barriers to obstruct the movement isotopic fuel.

(103) Modification of the invention herein disclosed will occur to persons skilled in the art and all such modifications are deemed to be within the scope of the invention as defined by the appended claims.
