The present inventions relate to methods, apparatuses, devices, and systems for creating, controlling, conducting, and optimizing fusion activities of nuclei.

For 60 years the science and technology communities have been striving to achieve controlled and economically viable fusion. The commonly held belief in the art is that another 25-50 years of research remain before fusion is a viable option for power generation-“As the old joke has it, fusion is the power of the future-and always will be” (“Next ITERation?”, Sep. 3, 2011, The Economist). Further, until the present inventions, it was believed that a paradigm existed in that achieving fusion of reactants was unobtainable without incredibly high temperatures for even the most likely reactants and even higher temperatures for other reactants. As a consequence, it was further believed that there was no reason to construct, or investigate the composition of, a nuclear fusion reactor with lower temperature reactant confinement.
Prior to the present inventions it was believed that the art in controlled fusion reactions taught that temperatures in excess of 150,000,000 degrees Centigrade were required to achieve favorable gross energy balance in a controlled fusion reactor. Gross energy balance, Q, is defined as:
where Efusion is the total energy released by fusion reactions and Ein is the energy used to create the reactions. The Joint European Torus, JET, claims to have achieved Q ˜ 0.7 and the US National Ignition Facility recently claims to have achieved a Q >1 (ignoring the very substantial energy losses of its lasers). The condition of Q=1, referred to as “breakeven,” indicates that the amount of energy released by fusion reactions is equal to the amount of energy input. In practice, a reactor used to produce electricity should exhibit a Q value significantly greater than 1 to be commercially viable, since only a portion of the fusion energy can be converted to a useful form. Conventional thinking holds that only strongly ionized plasmas, are necessary to achieve Q >1. These conditions limit the particle densities and energy confinement times that can be achieved in a fusion reactor. Thus, the art has looked to the Lawson criterion as the benchmark for controlled fusion reactions-a benchmark, it is believed, that no one has yet achieved when accounting for all energy inputs. The art's pursuit of the Lawson criterion, or substantially similar paradigms, has led to fusion devices and systems that are large, complex, difficult to manage, expensive, and economically unviable.
A common formulation of the Lawson criterion is as follows:
All of the parameters that go into the Lawson criterion will not be discussed here. But in essence, the criterion requires that the product of the particle density (N) and the energy confinement time (τE*) be greater than a number dependent on, among other parameters, reaction temperature (H) and the reactivity σv
ab, which is the average of the product of the reaction cross section and relative velocity of the reactants. In practice, this industry-standard paradigm suggests that temperatures in excess of 150,000,000 degrees Centigrade are required to achieve positive energy balance using a D-T fusion reaction. For proton-boron fusion, as one example, the criterion suggests that the product of density and confinement time must be yet substantially higher.
It should be noted that current fusion schemes using D-T fuels, which produce radioactive materials, should have shielding and take steps and precautions, such as the use of robotic operating systems to maintain safety.
An aspect of the Lawson criterion is based on the premise that thermal energy must be continually added to the plasma to replace lost energy to maintain the plasma temperature and to keep it fully or highly ionized. In particular, a major source of energy loss in conventional fusion systems is radiation due to electron bremsstrahlung and cyclotron motion as mobile electrons interact with ions in the hot plasma. The Lawson criterion was not formulated for fusion methods that essentially eliminate electron radiation loss considerations by avoiding the use of hot, heavily ionized plasmas with highly mobile electrons.
Because the conventional thinking holds that high temperatures and strongly ionized plasma are required, it was further believed in the art that inexpensive physical containment of the reaction was impossible. Accordingly, methods being pursued in the art are directed to complex and expensive schemes to contain the reaction, such as those used in magnetic confinement systems (e.g., the ITER tokamak) and in inertial confinement systems (e.g., NIF laser).
In fact, at least one source in the prior art expressly acknowledges the believed impossibility of containing a fusion reaction with a physical structure: “The simplest and most obvious method with which to provide confinement of a plasma is by a direct-contact with material walls, but is impossible for two fundamental reasons: the wall would cool the plasma and most wall materials would melt. We recall that the fusion plasma here requires a temperature of ˜108 K while metals generally melt at a temperature below 5000 K.” (“Principles of Fusion Energy,” A. A. Harms et. al.)
The present inventions break the prior art paradigms by, among other things, increasing the reactant density, essentially eliminating electron radiation losses, and combinations of these, by avoiding the use of a strongly ionized plasma, modifying the Coulomb barrier and thus increasing the reaction cross section, and essentially eliminating the need for confinement to contain the fusion reaction. Such approaches make Lawson's criterion inapposite.
The importance and value of achieving economically viable controlled fusion has long been recognized and sought after in the art. Controlled fusion may have applications in energy production, propulsion, material creation, material formation, the production of useful isotopes, generation of directed energetic beams and particles, and many other key fields and applications. In the energy production area, controlled fusion has been envisioned to provide a solution to global energy and environmental challenges, including supply, distribution, cost, and adverse effects from using hydrocarbon or other alternative fuel sources. Accordingly, there has been a long-standing and unfulfilled need for a controlled fusion reaction, and the clean energy and other benefits and beneficial uses that are associated with such a reaction. This need, however, has primarily focused on using controlled fusion for larger, or macro applications, such as providing power to a city, factory or building.
There has further been a long-standing need for reliable and dependable small power sources for use in small devices such as cell phones, robotics, hearing aids, pace makers, laptop computers, smart phones, hand held electronic devices and the like, as well as for newer, smaller, and emerging technologies, such as, nano-technologies, micro-circuits, nano-circuits and micro-robotics. While battery technologies and other power sources have been rapidly evolving and becoming smaller, and smaller, in many instances they have failed to keep up with the needs of smaller and smaller devices, and the need for having power supplies that do not readily become depleted. Unfortunately, in many cases, battery technology may be becoming the limiting factor to the further advancement of these small electronic technologies.
The present methods, devices and systems for conducting fusion reactions solve these and other problems, deficiencies, and inadequacies associated with prior attempts to create a viable controlled fusion system, and short comings in conventional small, micro-, nano-, and sub-nano-electronic devices. Further, the present inventions avoid the risks associated with conventional fission power generation. Moreover, available aneutronic embodiments of controlled fusion avoid the potential issues associated with managing neutrons produced in other fusion reactions, and make devices utilizing these embodiments readily usable in devices that are closely associated with living entities, e.g., a pace maker. Thus, the present inventions, among other things, solve these needs by providing the articles of manufacture, devices and processes taught, disclosed and claimed herein.
Thus, there are provided the methods, systems, articles and devices of the present specification, drawings and claims.
In general, the present inventions relate to methods, apparatuses, devices, and systems for creating, measuring, controlling, conducting, and optimizing fusion activities of nuclei. In particular, the present inventions relate to, among other things, fusion activities that are conducted individually on a very small scale; and for the utilization of the energy, materials, and particles that are produced from these small-scale fusion activities. The present inventions further related to, among other things, small devices for causing and controlling these small fusion activities, and utilizing the products of these fusion activities, as well as, the aggregation of these smaller devices and the utilization of the aggregation.
Generally, the present methods, apparatuses, and systems utilize the creation of submicron regions, and preferably nano regions (e.g., about one cubic nanometer, nm3, 10−27 m3) or smaller, of high charge densities to provide for controlled fusion reactions, and preferably with simple containment schemes (without the need for any complicated containment schemes), and more preferably without the need for any magnetic fields. Further, embodiments of the present inventions create or modify quantum and other effects to provide for, or enhance, the fusion reaction.
In general, embodiments of the controlled fusion devices cause electrons to form an area of high charge density associated within a base structure containing the reactants. In an embodiment the base structure has, is, or forms a lattice, mesh, cage, pores, other substructures, and combinations and variations of these. The base structure, and preferably the substructure, holds, carries, encapsulates, encompasses, replenishes, exposes, contains, supports, maintains and combinations and variations of these reactants. The high charge density associated with the base structure can be provided by causing the electrons to move in a manner that results in their collection, agglomerating, coming together, increasing density and combinations and variation of these.
Embodiments of the base structure material include, for example palladium, tungsten, boron hydride, titanium, tantalum, getter materials for hydrogen and low molecular weight gasses, and other materials that can support or carry the fusion fuel. The base structure may be a composite material, an alloy, a metal-ceramic, it may contain layers, the layers may be of the same or different materials, the layers may have the same or different substructures, initially underlying layers may over time become exposed to the reaction as the device operates, and combinations and variations of these and other configurations. Coatings may be used on the surface of the base structure, for example, gold, copper, silver or other conducting materials, and preferably materials having good conductivity, and having low resistance.
Embodiments of the base structure have a discontinuity. This discontinuity can be an area of discontinuity, or more preferably one or more points of discontinuity (It being understood that the point(s) may still have some area, but as used herein the point(s) of discontinuity generally refers to a generally circular shape, generally square shape, generally rectangular shape, generally elliptical shape or other shape having an area of about 1 μm2 or less, about 500 nm2 or less, about 100 nm2 or less, 50 nm2 or less and preferably about 10 nm2 or less). Generally, this discontinuity is associated with, preferably adjacent, and more preferably central to the area of high electron charge density. The discontinuity may be a knife edge, it may be an annular knife edge, and preferably it may be the tip, e.g., point, of a tapered member, such as a solid or tubular nano-needle. The base structure may contain one, two or more discontinuities. When multiple discontinuities are present they may be the same or different, for example, in terms of shape configuration, intended reactants or other attributes.
The fusion fuel may be any of the materials identified in this specification, as suitable for a fusion reaction or known to be useful in such a reaction, or later discovered to be useful, that can be loaded or otherwise incorporated into, or held by, the base structure, and more preferably the substructure of the base structure. Preferably, the fusion fuel is, for example hydrogen, deuterium, Boron-11, Helium-3, and mixtures of these. The fusion fuel is loaded or reloaded into the base structure. Preferably, the fusion fuel is loaded or reloaded into the discontinuity, and most preferably is load into the area where the high electron density will be present. Thus, in a preferred embodiment the fusion fuel is heavily loaded into the volume of the base structure that is in the area of the discontinuity and the area of high electron density, with the fusion fuel being held by the substructure.
It addition to the fusion fuel being preloaded into the base structure, the fusion fuel can be added continuously, batch wise, generated in situ during the fusion reaction (e.g., generation of 3He), between operations and combinations and variations of these. Thus, for example, a palladium tubular nano-needle base structure, having a closed tip to a needle point, can have its inner space filled with excess hydrogen (or in fluid communication with a source of hydrogen) so that as the hydrogen is depleted during operation the excess hydrogen will migrate, e.g., getter, into the base structure and thus re-load the structure with fusion fuel.
In an embodiment, the device can be operated without reloading or replenishing of the fusion fuel in the base structure. The device could be created with many base structures, only some of which operate at any given time, wherein the additional base structures would be activated when the fusion fuel is fully or partially depleted from the base structures that had previously been activated. Such an device would include a monitoring and control mechanism to successively turn off and on base structures in a desired manner.
The volume of fusion fuel, e.g., hydrogen to the volume of base structure material, e.g., palladium, can be significantly larger, providing advantages to the fusion reaction. The volume of fusion fuel can be 2× larger or more than the volume of base structure material, it can be 3× larger or more, it can be 5× larger or more, and it can be 7× larger or more, depending upon, among other things, the particular fusion fuel(s) used, base material used, and substructure present. For hydrogen fuel, palladium base structure embodiments, the hydrogen can be loaded to 8× the volume of the palladium.
Preferably, the fusion fuel can be loaded or reloaded into the base structure to particle densities of 1015 /cc or more, 1018 /cc or more, 1020 /cc or more, 1022 /cc or more, and more preferably about 1023 /cc. It being noted that the fusion fuel densities of the present inventions are substantially greater than the densities obtained in the larger magnetic containment fusion devices, such as the Tokamak reactors (reported to be limited to particle densities of 1014/cc).
The fusion fuel can be loaded or reloaded into the base structure by gettering, provided that the base structure-fusion fuel type exhibit this effect. The fusion fuel can be loaded or reloaded by any means or technique known to the art, or later developed, to incorporate or include smaller atomic scale particles into a larger matrix or supporting structure. The fusion fuel itself, may also be the base structure.
The region of high electron density can be provided by using a microwave generator, radio frequency (RF) wave generator, or similar device, associated with the base structure. In operation, the high electron density generator causes the electrons to move in a first direction along generally the surface of the base structure toward the discontinuity (forward electron flow), and then quickly reverses the flow of the electrons away from the discontinuity (reverse electron flow). In this manner the forward and reverse electron flows along generally the surface of the substructure creates a high electron density at the discontinuity. The base structure can be coated with a material to enhance or facilitate this flow of electrons along its surface, such as a gold coating, copper coating, silver coating or a coating of other conducting materials, and preferably materials having good conductivity, and having low resistance. This area of high electron density is present, e.g., exists, at its peak periodically. Typically the periodicity of the high electron density peak is at about the same frequency as that of the high electron density generator; although there may be doubling, and other effects that result in a differences between the two. For example the generator may operate at a wavelength of from about 10 microns to about 0.1 micron. The generator can also operate at wavelengths of x ray and gamma ray to reach higher electron densities. The power for these generators is minimal, requiring about 1 mW to about 10 mW, and generally less than about 1 mW per discontinuity.
A laser may also be directed on the discontinuity and establish a similar forward and reverse flow of electrons to establish an area of high electron density peaks. Laser wavelengths of from about_10 microns_to about_0.1 micron_, The laser power for the laser beam can be from about_1_nW to_1 _mW, about_1_mW to about_10_mW and generally less than about _1 _mW. The base structure can be coated with, or made from a material, that is selected to optimize the laser material interaction and more preferably to optimize both the laser material interaction and the flow of electrons.
In addition to the laser, microwave generator and RF generator, other manners of, devices for, generating the region of high density electrons can be used, for example magnetrons with cavities which can bundle electrons together to high densities or nonlinear effects in an electron-beam plasma where the electron wave can collapse three dimensionally to very small locations with high electron densities.
The region of high density electrons, in particular embodiments, can have particle densities of 1015 /cc or more, 1018 /cc or more, 1020 /cc or more, 1022 /cc or more, and about 1023 /cc or more. The electric field for these regions can be greater than about 108 V/m (volts/meter), greater than about 109 V/m, greater than about 1010 V/m and greater than about 1011 V/m.
The fusion fuel material may be, for example, hydrogen-1, boron-11, lithium-6, lithium-7, deuterium, helium-3, nitrogen-15, tritium. It may be advantageous to use molecular compounds that are good electron emitters, for example boron nitride or lanthanum hexaboride or cerium hexaboride and combinations and variations of these and other types of materials.
It should be understood that the figures in this specification are generally representative of very small components (e.g., micron, nano, and pico sizes). Thus, the figures are not to scale, and are illustrative of the relationships, structures and components of the various embodiments, and should be viewed as part of, and in the context of, the entirety of the teachings of this specification.
Turning to
The movement of the electrons is preferably collective, coherent, and both. Thus, it is theorized that this collective and coherent motion of electrons is similar to, and may be, the type of electron movement exhibited in superconductive materials. This collective and coherent electron motion, of the present inventions, takes place at room and elevated temperatures. Thus, the present invention provides for ambient temperature and above superconductivity, and superconductivity like behaviors in the movement of electrons.
Turning to
In operation it is believed that the creation of the area of high electron density enables, facilitates, or furthers the fusion reaction of the fusion fuel. It is theorized that among other things, the presence of the high electron density lowers the coulomb barrier, and preferably creates a negative well, that permits the fusion fuel, e.g., 106b, 106c, to fuse. Further, it is theorized that the highly localized electron density, creates a ponderomotive force that drives the fusion fuel together, and also drives the electrons into the substructure of the base material, enhancing the fusion reaction of the fusion fuel.
In one of the embodiments of the present invention, as shown in
In another embodiment, the excitation source, e.g. laser, diode laser, or RF/microwave generator, is integrated in or near the base structure of the device to optimizing coupling of radiation and miniaturization of the device.
The submicron controlled fusion device can be associated with a device for generating electricity. The devices would include, for example, sensor chips that have been adapted to generate a current, voltage or both in response to the heat generated by the fusion reaction, in response to the charged fusion product particles generated by the fusion reaction and both. Thus, as examples, (A) a radiation detection type diode can be adapted to produce electricity from the fusion products, (B) a thermoelectric device could convert a portion of the heat energy into electric current, (C) a fluid could be forced to flow, expand or incur a phase change so as create some electricity or other useful energy. The devices for generating electricity from the controlled fusion reaction could also include (D) mechanisms to slow the resulting charged particles by an electromagnetic field so as to effect a direct conversion to electricity and (E) mechanisms to put small electrodes adjacent to the discontinuity so as to have charged particles collide with one or the other of the electrodes and thereby induce a current or to recharge a connected battery or capacitor. The foregoing means could include combinations of the foregoing. For example, if the means of direct conversion to electricity was only partially efficient, it could be deployed in combination with a thermoelectric device to create electricity from the heat remaining after deployment of the direct conversion mechanism.
Although not required, the electrodes of the device could also be located in, or have a source of fusion fuel around their exterior, such as being contained in a closed micro-vessel, filled with, or having hydrogen flowed through it.
Generally, the term “about” is meant to encompass a variance or range of 10%, the experimental or instrument error associated with obtaining the stated value, and preferably the larger of these.
Embodiments of the present inventions may utilize quantum, electrostatic, mechanical, or other effects including, among other things, large E-fields, high electron densities, ponderomotive forces, modification or change of the Coulomb barrier, modification or change of the reaction cross section, space charge or electron shielding effects, the use of neutrals, ion-neutral coupling, nuclear magnetic moment interaction, spin polarization, magnetic dipole-dipole interaction, high particle density materials, compression forces associated with centrifugal forces or ponderomotive forces, phase transitions of hydrogen, positive feedback mechanisms, and modification and variations of these and other effects. All references in this specification to modifying, changing, lowering, reducing or eliminating the barrier include means by which the Coulomb barrier is offset by, or its effect is reduced by, the presence of one or more other features (e.g., high electron densities) even though the Coulomb barrier itself (independent of such features) remains unchanged.
It is noted that there is no requirement to provide or address the theory underlying the novel and groundbreaking fusion methods, devices and systems that are the subject of the present inventions. Nevertheless, these theories are provided to further advance the art in this important area. The theories put forth in this specification, unless expressly stated otherwise, in no way limit, restrict or narrow the scope of protection to be afforded the claimed inventions. These theories many not be required or practiced to utilize the present inventions. It is further understood that the present inventions may lead to new, and heretofore unknown theories to explain the fusion methods, devices and system of the present inventions, and such later developed theories shall not serve to diminish or limit the scope of protection afforded the claimed inventions.
In order to fuse, two nuclei must come into contact; however, nuclei are very small (on the order of 10−15 m), and because they are positively charged, they are electrostatically repulsed by one another. The potential energy curve of a two particle system 501 in which a first nucleus 502 is approaching a second nucleus is illustrated in
where v=V1 −v2, v1 and V2 are the velocities of the two nuclei, and mr is the reduced mass of the system, given by:
where m1 and m2 are the masses of the two nuclei. Classical mechanics holds that, when the nuclei are approaching one another, E must be greater than the height of the Coulomb barrier for the nuclei to come into contact. However, quantum mechanics allows for “tunneling” through a potential barrier, thus making fusion reactions possible when E is below this threshold. However, the magnitude of the barrier still presents an impediment to tunneling, such that reactions with larger Coulomb barriers (e.g., higher, wider, or both) are generally less likely to occur than those with smaller barriers.
Embodiments of the present invention may lower or reduce the Coulomb barrier, and may eliminate it to the extent of creating a well, by creating, modifying, or utilizing effects that have negative (attractive) potentials. Such a negative potential is illustrated in
Thus, for example, embodiments of the present invention may lower or reduce the Coulomb barrier through the use of effects such as: space charge or electron shielding effects; large E-fields, high electron densities, the use of neutrals; ion-neutral coupling; or nuclear magnetic moment interaction, spin polarization, or dipole-dipole interaction effects; and combinations and variations of these and other effects.
In general, a ponderomotive force is a force that is created from an oscillating electric field. The ponderomotive force affects both positive and negative charged particles the same, i.e., moving them in the same direction. Thus, the ponderomotive force is a rare case where the sign of the particle charge does not change the direction of the force, unlike the case with the Lorentz force. Thus, in embodiments of the present invention the ponderomotive force has the effect of crushing, or compacting the substructure containing the fusion fuel forcing the fusion fuel into contact and to fuse. The ponderomotive force Fp is expressed by
where e is the electrical charge of the particle, m is the mass, co is the angular frequency of oscillation of the field, and E is the amplitude of the electric field.
From this equation it is readily seen that the high E results in a strong ponderomotive force. However if the E field is at a high frequency, such as above the ion plasma frequency, then only the light electrons will be influenced by these fields. The heavier ions will nonetheless be influenced by the electron motion through the ambipolar electric field, which is the DC field generated when electrons are separated from the ions.
An advantage of using weakly ionized plasma is that the reactants largely comprise neutral atoms. The electrons interposed between the nuclei shield the repulsive Coulomb force between the positively charged nuclei. This phenomenon affects the Coulomb repulsion and may reduce the Coulomb barrier. In addition, using reactants that are highly efficient electron emitters introduces a cloud of electrons, a negative space charge, between the positively charged reactants, which further enhances this shielding effect. In an embodiment of the present invention, the high density electrons are driven by ponderomotive forces into the substructure, amongst the fusion fuel. It is believed that these electrons in the substructure provide an electron shielding effect which reduces the Coulomb barrier and enhances the fusion reaction rate. In a further embodiment, there is present in the system a material with a geometry or surface profile that creates non-uniform electric fields. Thus, by way of example, a surface with a dendritic profile may be desirable to generate very high localized electric fields for fusion.
Many nuclei have an intrinsic “spin,” a form of angular momentum, which is associated with their own internal spinning motion and resultant current. The magnetic field lines form as though one end of the nucleus were a magnetic north pole, and the other end were a magnetic south pole, leading the nucleus to be referred to as a “magnetic dipole,” and the strength and orientation of the dipole described as the “nuclear magnetic moment”, which is represented as a vector.
Nuclear magnetic moments play a role in quantum tunneling. Specifically, when the magnetic moments of two nuclei are parallel, an attractive force between the two nuclei is created. As a result, the total potential barrier between two nuclei with parallel magnetic moments is lowered, and a tunneling event is more likely to occur. The reverse is true when two nuclei have antiparallel magnetic moments, the potential barrier is increased, and tunneling is less likely to occur.
When the magnetic moment of a particular type of nucleus is positive, the nucleus tends to align its magnetic moment in the direction of an applied magnetic field. Conversely, when the moment is negative, the nucleus tends to align antiparallel to an applied field. Most nuclei, including most nuclei which are of interest as potential reactants, have positive magnetic moments (p, D, T, 6Li, 7Li, and “B all have positive moments; 3He, and 15N have negative moments). In an embodiment of a controlled fusion device a magnetic field may be provided that aligns the magnetic moments in approximately the same direction at every point within the device where a magnetic field is present. This results in a reduction of the total potential energy barrier between nuclei when the first and second working materials have nuclear magnetic moments which are either both positive or both negative. It is believed that this leads to an increased rate of tunneling and a greater occurrence of fusion reactions. This effect may also be referred to as spin polarization or magnetic dipole-dipole interaction. In addition, the gyration of a nucleus about a magnetic field line also contributes to determining the total angular momentum of the nucleus.
Hyperpolarization of Nuclei. Nuclei such as 3He can be polarized by collisions with alkali metal vapors or directly by RF fields in a weak magnetic field. This process can bring more than 90% of 3He atoms all aligned along the same direction, thereby increasing the attractiveness among them. The 3He 3He fusion reactions lead to the formation of 4He atom plus two energetic protons, a very desirable fusion reaction, because there are no neutrons in the product and the energy yield is very high, above 10 MeV.
Thus, although magnetic fields are not necessary with preferred embodiments of the present invention, e.g., “amagnetic”—a device free of additional, induced or provided magnetic fields, to obtain a controlled fusion reaction, they may be utilized to enhance, or optimize the fusion reaction and the performance of the device.
The probability of a fusion reaction between a pair of nuclei is expressed by the reaction cross section, “σ.” The cross section is typically measured in experiments as a function of ϵ(energy) by bombarding a stationary target of nuclei with a beam of nuclei. The cross section is normally defined such that:
where B is the number of reactions per unit time per target nucleus, and 1 is the number of incident particles per unit time per unit target area. When cross section is defined and measured in this way, each fusion reaction will have a certain, specific cross section at a particular E for a given system.
The fusion reaction rate per unit volume in a particular reactor is normally described by:
where δ12=1 if the first nucleus and the second nucleus are the same type of nuclei (e.g., deuterium is being fused with deuterium) and δ12=0 otherwise, and σv
is the “averaged reactivity” of the system, defined as:
σν
=∫0∞σ(ν)νƒ(ν)dν
where ƒ(ν) is the distribution function of the relative velocities, normalized in such a way that ∫0∞ƒ(ν) dν=1. When the second nucleus is at rest, σν
=σν; however, the preceding definition accounts for situations in which the second nucleus moves, and each pair of interacting nuclei may have a different relative velocity ν.
The rate of fusion energy release is then given by:
where W is the total fusion energy per unit volume released and E is the energy released by a single reaction (E=8.68 MeV in the case of p-11 B fusion).
The probability of the two nuclei coming into contact through a quantum tunneling event is described by the tunneling barrier transparency, “T,” such that a higher value of T corresponds to greater likelihood of tunneling. Since tunneling is the primary mechanism by which fusion occurs, cross section is proportional to T (σ∝T). T is approximated by:
where e is Euler's number, and ϵG is the modified energy of the Coulomb barrier. When the two nuclei are a distance x ≥XT apart, ϵG is described by:
ϵG∝∫x
where, q1 is the charge of the first nucleus, φ(x) is the potential expressed as a function of x, and XT is the classical turning point at which φ(xT)=ϵ.
As a result of these relationships, a higher value of p (e.g., larger Coulomb barrier) will tend to translate into higher ϵG, which in turn will tend to lead to lower T, lower a, lower R, and, when E >0, lower
for any specific system. Thus, systems in which potential p is high will tend to experience fewer fusion events and lower fusion energy release rates, and systems in which potential p is low will tend to experience more fusion events and higher fusion energy release rates. As discussed above, reducing the Coulomb barrier is equivalent to reducing potential φ, and embodiments of the present invention may employ these techniques to generally increase the cross section, σ; this also increases the fusion reaction rate.
An embodiment of the present invention, instead of creating a strongly ionized plasma to obtain a high particle density, loads the substructure with significantly more, e.g., high density of, particles than is believed to be obtainable by any plasma. As the particles are essentially held in a solid, or are a solid material, this approach does not give rise to plasma instabilities, and so particle density (ni and n2) can be many orders of magnitude higher than with a strongly ionized plasma, and many orders of magnitude higher than obtainable with weakly ionized plasma where its neutral density is at least 1017/cm3. In an embodiment of the present invention, particle density is throughout the entire volume of the device. Further, the compression induced by the centrifugal force leads to an increased density of particles in the region in which fusion events are expected to be concentrated, leading to densities of about 1018/cm3 or higher in the region of the device where reactants are concentrated.
In addition, an embodiment of the present invention uses boron compounds in a solid form, which have a particle density on the order of 1023/cm3. Thus, in the region where fusion reactions are thought to be concentrated, the present invention achieves particle densities in a physical container many orders of magnitude greater than other methods known in the art (for example, it is believed that Tokamak reactors have not achieved sustained particle densities greater than about 1014/cm3).
An advantage of the present inventions is that they effectively suppress radiation losses due to electron bremsstrahlung. Conventional fusion reactors such as Tokamaks employ hot, highly ionized plasma. Electron-ion interaction, resulting in bremsstrahlung and cyclotron radiation, is a significant source of energy loss and is one of the reasons such systems have not been able to satisfy the Lawson criterion. However, the high-density, lightly ionized, and colder plasma employed in embodiments of the present inventions suppresses electron mobility and greatly reduces radiative losses.
Hydrogen atoms under high pressure compression can become liquid or solid metals, depending on the compressional forces and their states of rotation. In either the liquid or solid states, the density is many orders of magnitude higher than that in the gaseous state. The total reaction rate will be correspondingly higher according to the product of the particle densities of the two reactants.
In addition, metallic hydrogen becomes highly conductive or even a superconductor with zero resistance. This increases the overall conductivity of the entire system, lowering the resistive loss and the input energy required. Thus, the overall efficiency of such a system is greater, making it easier to attain a large Q factor and the corresponding energy gain.
The present invention may generate particles during operation. In some cases these particles may provide benefit to the device's function. In embodiments utilizing ionized particles, the creation of ionizing radiation may further enhance additional fusion by increasing, modifying, maintaining, or improving the ionization or a working material or plasma.
The key feature of this new fusion concept depends on the screening effect of electrons around the neutrals. It is expected that the fusion process will release more electrons through heating or collisions with fusion products. These processes could cause larger electron density fluctuations, including Langmuir collapses [1, 12]. This type of positive feedback generates stronger screening effects and could create sustainable fusion process for energy production.

The electrical generation assembly of Example 4 powers a circuit in an electronic device. The electronic device can be a cell phone, a hearing aid, a pace maker, a glucose pump, an in situ diagnostic and metering system for the sensing of conditions, and delivery of medicaments. In embodiments, the device could be an independent unit with a primary function of providing electricity and/or heat to some other device (e.g., computers, cars, homes, etc.) including, by being connected to provide electricity and/or heat temporarily to one device (e.g., a car) and then disconnected from that device and connected to another device (e.g., a home). The development of such independent devices could also allow the rollout of electricity to lesser developed countries without the concurrent need to build transmission and distribution systems in the same way that lesser developed countries were able to build communications networks primarily by wireless means without having to build the wire infrastructure that the developed countries had built for communications prior to the development of wireless technologies.

Estimate of oscillating E fields and the associated Ponderomotive Force-and effective Potential.
Fe=−ωpe2/ω2[grad ∈oEosc2/2]newtons/m3
Electrons undergoes a drift motion driven by this ponderomotive force Fe; the ambipolar electric field generated by the separation between electrons and ions transmit the same force to ions.
The force experienced by an ion, fion, is obtained by dividing the above force, Fe,by the density of ions:
fion=-ne/ ni nf [grad E. Esse 2/2] newtons, where nfl=E. W2 me / e2
For ne/ni ˜ 1, nf=4×1016/m3
ion ˜ 8.8×10-12 (300)2 / 8×1016 (10-8)3 ˜ 10 N.
The equivalent potential felt by the ion is then Φ=fion x/q =106 volts, the distance x between two D atoms being taken to be 10−14 m where the repulsion barrier is greatest.
The equivalent potential is 106 volts which is of the order of the Coulomb barrier, resulting in fusion through quantum tunneling.

Laser-excited E2 is 109 larger than previous electric dipole excitation at microwave frequencies. However the number density of ions is larger.
The laser excitation might be more efficient than microwave excitation. It can also be more easily implemented experimentally.

fion˜8.8×10 −12 1030 / 3.2×1025 10−8 ˜27N.
The equivalent potential felt by the ion is then (=fionx/q =2.7×106 volts, the distance x between two D atoms being taken to be 10−14 m where the repulsion barrier is greatest.
The equivalent potential is 2.7×106 volts which is of the order of the coulomb barrier, resulting in fusion through quantum tunneling.
In an embodiment the fuel loaded into the base structure is a radioisotope. In this embodiment the decay of the radioisotope is regulated. In general, the Coulomb barrier acts as an impediment to the decay of radioisotopes. The mechanisms described in these embodiment could be deployed to reduce the Coulomb barrier so as to cause the decay of a radioisotope to occur at a faster rate than the natural “half-life” for such radioisotope.
The ability to increase the rate of decay of a radioisotope could be useful for the treatment of fission nuclear waste. One particularly favorable application would be to isolate and treat the most dangerous materials (whether elements or isotopes) with long half-lives so as to reduce such materials to stable (or at least less dangerous) elements or isotopes and to avoid having to construct storage mechanisms that need to be effective for very long periods (often many generations).
The ability to increase the rate of decay of a radioisotope could also be useful to create a device that would rely on the release of charged energetic particles for the production of electricity. By being able to increase the rate of decay of a radioisotope, the power output of the device could be materially increased without having to increase the amount of radioisotope that would need to be loaded into the device.
