Disclosed herein are catalyst systems to release energy from atomic hydrogen to form lower energy states wherein the electron shell is at a closer position relative to the nucleus. The released power is harnessed for power generation and additionally new hydrogen species and compounds are desired products. These energy states are predicted by classical physical laws and require a catalyst to accept energy from the hydrogen in order to undergo the corresponding energy-releasing transition.


Classical physics gives closed-form solutions of the hydrogen atom, the hydride ion, the hydrogen molecular ion, and the hydrogen molecule and predicts corresponding species having fractional principal quantum numbers. Atomic hydrogen may undergo a catalytic reaction with certain species, including itself, that can accept energy in integer multiples of the potential energy of atomic hydrogen, m·27.2 eV, wherein m is an integer. The predicted reaction involves a resonant, nonradiative energy transfer from otherwise stable atomic hydrogen to the catalyst capable of accepting the energy. The product is H(1/p), fractional Rydberg states of atomic hydrogen called “hydrino atoms,” wherein n=1/2, 1/3, 1/4, . . . , 1/p (p≤137 is an integer) replaces the well-known parameter n=integer in the Rydberg equation for hydrogen excited states. Each hydrino state also comprises an electron, a proton, and a photon, but the field contribution from the photon increases the binding energy rather than decreasing it corresponding to energy desorption rather than absorption. Since the potential energy of atomic hydrogen is 27.2 eV, m H atoms serve as a catalyst of m·27.2 eV for another (m+1)th H atom [1]. For example, a H atom can act as a catalyst for another H by accepting 27.2 eV from it via through-space energy transfer such as by magnetic or induced electric dipole-dipole coupling to form an intermediate that decays with the emission of continuum bands with short wavelength cutoffs and energies of m2·13.6 eV

.




In addition to atomic H, a molecule that accepts m·27.2 eV from atomic H with a decrease in the magnitude of the potential energy of the molecule by the same energy may also serve as a catalyst. The potential energy of H2O is 81.6 eV. Then, by the same mechanism, the nascent H2O molecule (not hydrogen bonded in solid, liquid, or gaseous state) formed by a thermodynamically favorable reduction of a metal oxide is predicted to serve as a catalyst to form H(1/4) with an energy release of 204 eV, comprising an 81.6 eV transfer to HOH and a release of continuum radiation with a cutoff at 10.1 nm (122.4 eV).

and extending to longer wavelengths than the corresponding cutoff. Here the extreme-ultraviolet continuum radiation band due to the decay of the H*[aH/4] intermediate is predicted to have a short wavelength cutoff at E=m2·13.6=9·13.6=122.4 eV (10.1 nm) [where p=m+1=4 and m=3 in Eq. (9)] and extending to longer wavelengths. The continuum radiation band at 10.1 nm and going to longer wavelengths for the theoretically predicted transition of H to lower-energy, so called “hydrino” state H(1/4), was observed only arising from pulsed pinch gas discharges comprising some hydrogen. Another observation predicted by Eqs. (1) and (5) is the formation of fast, excited state H atoms from recombination of fast H+. The fast atoms give rise to broadened Balmer α emission. Greater than 50 eV Balmer a line broadening that reveals a population of extraordinarily high-kinetic-energy hydrogen atoms in certain mixed hydrogen plasmas is a well-established phenomenon wherein the cause is due to the energy released in the formation of hydrinos. Fast H was previously observed in continuum-emitting hydrogen pinch plasmas.


Additional catalyst and reactions to form hydrino are possible. Specific species (e.g. He+, Ar+, Sr+, K, Li, HCl, and NaH, OH, SH, SeH, nascent H2O, nH (n=integer)) identifiable on the basis of their known electron energy levels are required to be present with atomic hydrogen to catalyze the process. The reaction involves a nonradiative energy transfer followed by q·13.6 eV continuum emission or q·13.6 eV transfer to H to form extraordinarily hot, excited-state H and a hydrogen atom that is lower in energy than unreacted atomic hydrogen that corresponds to a fractional principal quantum number.

Hydrogen is a special case of the stable states given by Eqs. (10) and (12) wherein the corresponding radius of the hydrogen or hydrino atom is given by

(

where p=1,2,3, . . . . In order to conserve energy, energy must be transferred from the hydrogen atom to the catalyst in units of an integer of the potential energy of the hydrogen atom in the normal n=1 state, and the radius transitions to

Hydrinos are formed by reacting an ordinary hydrogen atom with a suitable catalyst having a net enthalpy of reaction of





m·27.2 eV   (14)


where m is an integer. It is believed that the rate of catalysis is increased as the net enthalpy of reaction is more closely matched to m·27.2 eV. It has been found that catalysts having a net enthalpy of reaction within ±10%, preferably ±5%, of m·27.2 eV are suitable for most applications.


The catalyst reactions involve two steps of energy release: a nonradiative energy transfer to the catalyst followed by additional energy release as the radius decreases to the corresponding stable final state. Thus, the general reaction is given by

From Eq. (19), the calculated ionization energy of the hydride ion is 0.75418 eV , and the experimental value is 6082.99±0.15 cm−1 (0.75418 eV). The binding energies of hydrino hydride ions may be measured by X-ray photoelectron spectroscopy (XPS).


Upfield-shifted NMR peaks are direct evidence of the existence of lower-energy state hydrogen with a reduced radius relative to ordinary hydride ion and having an increase in diamagnetic shielding of the proton. The shift is given by the sum of the contributions of the diamagnetism of the two electrons and the photon field of magnitude p (Mills GUTCP Eq. (7.87)):

where the first term applies to H with p=1 and p=integer >1 for H(1/p) and α is the fine structure constant. The predicted hydrino hydride peaks are extraordinarily upfield shifted relative to ordinary hydride ion. In an embodiment, the peaks are upfield of TMS. The NMR shift relative to TMS may be greater than that known for at least one of ordinary H, H, H2, or H+ alone or comprising a compound. The shift may be greater than at least one of 0, −1, −2, −3, −4, −5, −6, −7, −8, −9, −10, −11, −12, −13, −14, −15, −16, −17, −18, −19, −20, −21, −22, −23, −24, −25, −26, −27, −28, −29, −30, −31, −32, −33, −34, −35, −36, −37, −38, −39, and −40 ppm. The range of the absolute shift relative to a bare proton, wherein the shift of TMS is about −31.5 relative to a bare proton, may be −(p29.9+p22.74) ppm (Eq. (20)) within a range of about at least one of ±5 ppm, ±10 ppm, ±20 ppm, ±30 ppm, ±40 ppm, ±50 ppm, ±60 ppm, ±70 ppm, ±80 ppm, ±90 ppm, and ±100 ppm. The range of the absolute shift relative to a bare proton may be −(p29.9+p21.59×10−3) ppm (Eq. (20)) within a range of about at least one of about 0.1% to 99%, 1% to 50%, and 1% to 10%. In another embodiment, the presence of a hydrino species such as a hydrino atom, hydride ion, or molecule in a solid matrix such as a matrix of a hydroxide such as NaOH or KOH causes the matrix protons to shift upfield. The matrix protons such as those of NaOH or KOH may exchange. In an embodiment, the shift may cause the matrix peak to be in the range of about —0.1 ppm to −5 ppm relative to TMS. The NMR determination may comprise magic angle spinning nuclear magnetic resonance spectroscopy (MAS NMR).


H (1/p) may react with a proton and two H (1/p) may react to form H2 (1/p)+ and H2 (1/p), respectively. The hydrogen molecular ion and molecular charge and current density functions, bond distances, and energies were solved from the Laplacian in ellipsoidal coordinates with the constraint of nonradiation.

H2(1/p) may be identified by X-ray photoelectron spectroscopy (XPS) wherein the ionization product in addition to the ionized electron may be at least one of the possibilities such as those comprising two protons and an electron, a hydrogen (H) atom, a hydrino atom, a molecular ion, hydrogen molecular ion, and H2(1/p) wherein the energies may be shifted by the matrix.


The NMR of catalysis-product gas provides a definitive test of the theoretically predicted chemical shift of H2(1/p). In general, the 1H NMR resonance of H2(1/p) is predicted to be upfield from that of H2 due to the fractional radius in elliptic coordinates wherein the electrons are significantly closer to the nuclei. The predicted shift,

The experimental absolute H2 gas-phase resonance shift of −28.0 ppm is in excellent agreement with the predicted absolute gas-phase shift of −28.01 ppm (Eq. (28)). The predicted molecular hydrino peaks are extraordinarily upfield shifted relative to ordinary H2. In an embodiment, the peaks are upfield of TMS. The NMR shift relative to TMS may be greater than that known for at least one of ordinary H, H2, or H+ alone or comprising a compound. The shift may be greater than at least one of 0, −1, −2, −3, −4, −5, −6, −7, −8, −9, −10, −11, −12, −13, −14, −15, −16, −17, −18, −19, −20, −21, −22, −23, −24, −25, −26, −27, −28, −29, −30, −31, −32, −33, −34, −35, −36, −37, −38, −39, and −40 ppm. The range of the absolute shift relative to a bare proton, wherein the shift of TMS is about −31.5 ppm relative to a bare proton, may be −(p28.01+p22.56) ppm (Eq. (28)) within a range of about at least one of ±5 ppm, ±10 ppm, ±20 ppm, ±30 ppm, ±40 ppm, ±50 ppm, ±60 ppm, ±70 ppm, ±80 ppm, ±90 ppm, and ±100 ppm.

In an embodiment, the molecular hydrino product is observed as an inverse Raman effect (IRE) peak at about 1950 cm−1. The peak is enhanced by using a conductive material comprising roughness features or particle size comparable to that of the Raman laser wavelength that supports a Surface Enhanced Raman Scattering (SERS) to show the IRE peak.


I. Catalysts


In the present disclosure the terms such as hydrino reaction, H catalysis, H catalysis reaction, catalysis when referring to hydrogen, the reaction of hydrogen to form hydrinos, and hydrino formation reaction all refer to the reaction such as that of Eqs. (15-18)) of a catalyst defined by Eq. (14) with atomic H to form states of hydrogen having energy levels given by Eqs. (10) and (12). The corresponding terms such as hydrino reactants, hydrino reaction mixture, catalyst mixture, reactants for hydrino formation, reactants that produce or form lower-energy state hydrogen or hydrinos are also used interchangeably when referring to the reaction mixture that performs the catalysis of H to H states or hydrino states having energy levels given by Eqs. (10) and (12).


The catalytic lower-energy hydrogen transitions of the present disclosure require a catalyst that may be in the form of an endothermic chemical reaction of an integer m of the potential energy of uncatalyzed atomic hydrogen, 27.2 eV, that accepts the energy from atomic H to cause the transition. The endothermic catalyst reaction may be the ionization of one or more electrons from a species such as an atom or ion (e.g. m=3 for Li→Li2) and may further comprise the concerted reaction of a bond cleavage with ionization of one or more electrons from one or more of the partners of the initial bond (e.g. m=2 for NaH→Na2++H). He+ fulfills the catalyst criterion—a chemical or physical process with an enthalpy change equal to an integer multiple of 27.2 eV since it ionizes at 54.417 eV, which is 2·27.2 eV. An integer number of hydrogen atoms may also serve as the catalyst of an integer multiple of 27.2 eV enthalpy. catalyst is capable of accepting energy from atomic hydrogen in integer units of one of about

In other embodiments, MH type hydrogen catalysts to produce hydrinos provided by the transfer of an electron to an acceptor A, the breakage of the M—H bond plus the ionization of t electrons from the atom M each to a continuum energy level such that the sum of the electron transfer energy comprising the difference of electron affinity (EA) of MI-1 and A, M—H bond energy, and ionization energies of the t electrons from M is approximately m·27.2 eV where m is an integer. MH type hydrogen catalysts capable of providing a net enthalpy of reaction of approximately m·27.2 eV are OH, SiH, CoH, NiH, and SeH.


In other embodiments, MH+ type hydrogen catalysts to produce hydrinos are provided by the transfer of an electron from an donor A which may be negatively charged, the breakage of the M—H bond, and the ionization of t electrons from the atom M each to a continuum energy level such that the sum of the electron transfer energy comprising the difference of ionization energies of MH and A, bond M—H energy, and ionization energies of the t electrons from M is approximately m·27.2 eV where m is an integer.


In an embodiment, at least one of a molecule or positively or negatively charged molecular ion serves as a catalyst that accepts about m27.2 eV from atomic H with a decrease in the magnitude of the potential energy of the molecule or positively or negatively charged molecular ion by about m27.2 eV. Exemplary catalysts are H2O, OH, amide group NH2, and H2S.


O2 may serve as a catalyst or a source of a catalyst. The bond energy of the oxygen molecule is 5.165 eV, and the first, second, and third ionization energies of an oxygen atom are 13.61806 eV, 35.11730 eV, and 54.9355 eV, respectively. The reactions O2→O+O2+, O2→O+O3+, and 2O→2O+ provide a net enthalpy of about 2, 4, and 1 times Eh, respectively, and comprise catalyst reactions to form hydrino by accepting these energies from H to cause the formation of hydrinos.

In an embodiment, H2O is ignited to form hydrinos with a high release of energy in the form of at least one of thermal, plasma, and electromagnetic (light) power. (“Ignition” in the present disclosure denotes a very high reaction rate of H to hydrinos that may be manifest as a burst, pulse or other form of high power release.) H2O may comprise the fuel that may be ignited with the application a high current such as one in the range of about 100 A to 100,000 A. This may be achieved by the application of a high voltage such as about 5,000 to 100,000 V to first form highly conducive plasma such as an arc. Alternatively, a high current may be passed through a compound or mixture comprising H2O wherein the conductivity of the resulting fuel such as a solid fuel is high. (In the present disclosure a solid fuel is used to denote a reaction mixture that forms a catalyst such as HOH and H that further reacts to form hydrinos. The plasma volatge may be low such as in the range of about 1 V to 100V. However, the reaction mixture may comprise other physical states than solid. In embodiments, the reaction mixture may be at least one state of gaseous, liquid, molten matrix such as molten conductive matrix such a molten metal such as at least one of molten silver, silver-copper alloy, and copper, solid, slurry, sol gel, solution, mixture, gaseous suspension, pneumatic flow, and other states known to those skilled in the art.) In an embodiment, the solid fuel having a very low resistance comprises a reaction mixture comprising H2O. The low resistance may be due to a conductor component of the reaction mixture. In embodiments, the resistance of the solid fuel is at least one of in the range of about 10−9 ohm to 100 ohms, 10−8 ohm to 10 ohms, 10−3 ohm to 1 ohm, 10−4 ohm to 10−1 ohm, and 10−4 ohm to 10−2 ohm. In another embodiment, the fuel having a high resistance comprises H2O comprising a trace or minor mole percentage of an added compound or material. In the latter case, high current may be flowed through the fuel to achieve ignition by causing breakdown to form a highly conducting state such as an arc or arc plasma.


In an embodiment, the reactants can comprise a source of H2O and a conductive matrix to form at least one of the source of catalyst, the catalyst, the source of atomic hydrogen, and the atomic hydrogen. In a further embodiment, the reactants comprising a source of H2O can comprise at least one of bulk H2O, a state other than bulk H2O, a compound or compounds that undergo at least one of react to form H2O and release bound H2O. Additionally, the bound H2O can comprise a compound that interacts with H2O wherein the H2O is in a state of at least one of absorbed H2O, bound H2O, physisorbed H2O, and waters of hydration. In embodiments, the reactants can comprise a conductor and one or more compounds or materials that undergo at least one of release of bulk H2O, absorbed H2O, bound H2O, physisorbed H2O, and waters of hydration, and have H2O as a reaction product. In other embodiments, the at least one of the source of nascent H2O catalyst and the source of atomic hydrogen can comprise at least one of: (a) at least one source of H2O; (b) at least one source of oxygen, and (c) at least one source of hydrogen.


In an embodiment, the hydrino reaction rate is dependent on the application or development of a high current. In an embodiment of an SF-CIHT cell, the reactants to form hydrinos are subject to a low voltage, high current, high power pulse that causes a very rapid reaction rate and energy release. In an exemplary embodiment, a 60 Hz voltage is less than 15 V peak, the current ranges from 100 A/cm2 and 50,000 A/cm2 peak, and the power ranges from 1000 W/cm2 and 750,000 W/cm2. Other frequencies, voltages, currents, and powers in ranges of about 1/100 times to 100 times these parameters are suitable. In an embodiment, the hydrino reaction rate is dependent on the application or development of a high current. In an embodiment, the voltage is selected to cause a high AC, DC, or an AC-DC mixture of current that is in the range of at least one of 100 A to 1,000,000 A, 1 kA to 100,000 A, 10 kA to 50 kA. The DC or peak AC current density may be in the range of at least one of 100 A/cm2 to 1,000,000 A/cm2, 1000 A/cm2 to 100,000 A/cm2, and 2000 A/cm2 to 50,000 A/cm2. The DC or peak AC voltage may be in at least one range chosen from about 0.1 V to 1000 V, 0.1 V to 100 V, 0.1 V to 15 V, and 1 V to 15 V. The AC frequency may be in the range of about 0.1 Hz to 10 GHz, 1 Hz to 1 MHz, 10 Hz to 100 kHz, and 100 Hz to 10 kHz. The pulse time may be in at least one range chosen from about 10−6 s to 10 s, 10−5 s to 1 s, 10−4 s to 0.1 s, and 10−3 s to 0.01 s.


In an embodiment, the transfer of energy from atomic hydrogen catalyzed to a hydrino state results in the ionization of the catalyst. The electrons ionized from the catalyst may accumulate in the reaction mixture and vessel and result in space charge build up. The space charge may change the energy levels for subsequent energy transfer from the atomic hydrogen to the catalyst with a reduction in reaction rate. In an embodiment, the application of the high current removes the space charge to cause an increase in hydrino reaction rate. In another embodiment, the high current such as an arc current causes the reactant such as water that may serve as a source of H and HOH catalyst to be extremely elevated in temperature. The high temperature may give rise to the thermolysis of the water to at least one of H and HOH catalyst. In an embodiment, the reaction mixture of the SF-CIHT cell comprises a source of H and a source of catalyst such as at least one of nH (n is an integer) and HOH. The at least one of nH and HOH may be formed by the thermolysis or thermal decomposition of at least one physical phase of water such as at least one of solid, liquid, and gaseous water. The thermolysis may occur at high temperature such as a temperature in at least one range of about 500K to 10,000K, 1000K to 7000K, and 1000K to 5000K. In an exemplary embodiment, the reaction temperature is about 3500 to 4000K such that the mole fraction of atomic H is high as shown by J. Lede, F. Lapicque, and J Villermaux [J. Lede, F. Lapicque, J. Villermaux, “Production of hydrogen by direct thermal decomposition of water”, International Journal of Hydrogen Energy, 1983, V8, 1983, pp. 675-679; H. H. G. Jellinek, H. Kachi, “The catalytic thermal decomposition of water and the production of hydrogen”, International Journal of Hydrogen Energy, 1984, V9, pp. 677-688; S. Z. Baykara, “Hydrogen production by direct solar thermal decomposition of water, possibilities for improvement of process efficiency”, International Journal of Hydrogen Energy, 2004, V29, pp. 1451-1458; S. Z. Baykara, “Experimental solar water thermolysis”, International Journal of Hydrogen Energy, 2004, V29, pp. 1459-1469 which are herein incorporated by reference]. The thermolysis may be assisted by a solid surface such as one of the cell compoments. The solid surface may be heated to an elevated temperature by the input power and by the plasma maintained by the hydrino reaction. The thermolysis gases such as those down stream of the ignition region may be cooled to prevent recombination or the back reaction of the products into the starting water. The reaction mixture may comprise a cooling agent such as at least one of a solid, liquid, or gaseous phase that is at a lower temperature than the temperature of the product gases. The cooling of the thermolysis reaction product gases may be achieved by contacting the products with the cooling agent. The cooling agent may comprise at least one of lower temperature steam, water, and ice.


The SunCell® may comprise a thermolysis hydrogen generator comprising a SunCell® radiator, a metal oxide, a water source, a water sprayer, and a hydrogen and oxygen gas collection system. The blackbody radiation from the blackbody radiator 5b4 may be incident a metal oxide that decomposes to oxygen and the metal upon heating.

In another embodiment, the levels are equalized by a conduit connecting the two reservoirs with a drip edge at each end of the conduit to prevent a short between the two reservoirs. Silver in an over-filled reservoir flows back to the other through the conduit to more equalize the levels.


In an embodiment, the molten metal levels between reservoirs 5c remain essentially the same by at least one of active and passive mechanisms. The active mechanism may comprise adjusting the EM pump rate in response to the molten metal level measured by the sensor. The passive mechanism may comprise a spontaneous increase in molten metal rate through the EM pump due to an increased head pressure when the molten metal level is elevated in the corresponding reservoir. The head pressure may contribute to a fixed or varied EM pump pressure to maintain the about equal reservoir levels. In an embodiment, the reservoir height is sufficient to given rise to a sufficient head pressure differential between the extremes comprising the lowest and highest desired molten metal levels to maintain the reservoir levels about the same during operation. The maintenance may be achieved due to the differential flow rate due to a differential head pressure corresponding to a differential in molten metal level between the reservoirs.


In an embodiment, the EM pump comprises an inlet riser 5qa (FIG. 2I138) comprising a plurality of molten metal inlet openings or apertures on the inlet riser. The inlet riser 5qa may comprise a hollow conduit such as a tube. The conduit may be connected to the EM pump tube 5k6 on the inlet side of the EM pump magnets 5k4. The connection may be at the base of the EM pump assembly 5kk. The connection may comprise one of the disclosure such as matching threads or a Swagelok. The inlet riser may comprise a refractory material such as a refractory metal, carbon, or a ceramic such as one of W, Mo, SiC, boron nitride, and other refractory materials of the disclosure. The inlet riser may have a lower height than that of the nozzle 5q to reduce or eliminate the potential for the ignition current to electrically short to the inlet riser tube. In an embodiment, the lowest inlet to the inlet riser may be at a greater height than the top of the nozzle 5q of the EM pump injector such that the nozzle remains submerged. The submerged nozzle may be the positive electrode that may be submerged to protect it form the hydrino reaction plasma. The inlet riser may be non-conducting. The inlet riser may be coated with a coating such as a coating of the disclosure. The coating may be a non-conductor.

The tube may screw into the inlet and outlet of the EM pump at the base of the EM pump tube assembly 5kk, respectively. An exemplary inlet riser of a reservoir having a submerged nozzle comprises a BN tube threaded into the EM pump assembly base at the EM pump outlet; the inlet comprising a V-shaped slot on the side of the tube and an open top with the bottom of the V at a greater height than the height of the tip of the nozzle such that the nozzle remains submerged wherein the nozzle may comprise the positive electrode.

An exemplary upper inlet riser tube section comprises BN that may be at least one of threaded into and compression fit to the lower tube portion.


The inlet openings may get smaller from top to bottom of the inlet riser to automatically control the pump rate and silver level by controlling the inlet flow rate to the EM pump. In an embodiment, the inlet riser 5qa comprises vertically spaced openings such that as the reservoir molten metal level increases the EM pumping rate increases due to at least one effect of (i) the molten metal flows into the inlet riser faster since the total opening cross section increases with molten metal level height, (ii) the molten metal height in the inlet riser increases as the molten metal level increases with a corresponding increase in EM pump head pressure, and (iii) the decrease in flow restriction due to the larger total opening cross section or area decreases any corresponding pressure drop according to Bernoulli's equation and may further add head pressure in the case that the inlet flow rate is limiting to the filling of the inlet riser to its maximum height in the absence of flow restriction. In contrast, the counter inlet riser and injector of a dual injector electrode system may experience the opposite effects and a corresponding decreasing EM pumping rate due to a dropping relative molten metal level. In an alternative embodiment to the plurality of vertically spaced openings that may progressing restrict inlet flow from top to bottom over the span of the openings, the inlet riser may comprise at least one vertical slot at the top end of the inlet riser that may span a height range such as that of the desired height range of the molten metal level.

The molten metal levels tend towards balancing due to the automatic inflow and corresponding pumping rate adjustment as a function of the relative molten metal levels of the reservoirs of the EM pump-driven dual molten metal injector electrodes. The EM pumps of each injector may be set at about a constant current. The current may be sufficient to cause intersection of the dual injected metal streams at about the center of the reaction cell chamber 5b31 with small variations to either side off center over the range of pumping rates caused the level changes and corresponding pump inflow and EM pumping rates. The current supplied by each EM pump power supply 5k13 may be set at a desired constant level.

Each EM pump current may be sensed by its current sensor and adjusted by a controller to give a desired initial ignition current as measured by an ignition current sensor and processed by a processor. An ignition controller may also control the ignition power parameters. The current may be maintained within a range that provides stability of the intersection of the molten metal streams in the about middle of the reaction cell chamber. In an exemplary embodiment, the current is maintained above the threshold for the streams to intersect and below a level that would cause one stream to propagate to the opposite reservoir in the absence of the intersection. An exemplary current range for each EM pump current is about 300 A to 550 A. The currents of both pumps may be about equal.


The EM pump rate may be controlled by at least one of the inlet flow rate control by the level-height-dependent inlet riser inflow cross section and by the molten metal level sensor, the level processor, and the EM pump current controller. The change in at least one of resistance, current, voltage, and power of the EM pump power supply 5k13 may be sensed with a corresponding sensor, and the EM pump current may be controlled to further control the relative EM pumping rates to achieve about balance between the reservoir molten metal levels. In an embodiment, the EM pump 5ka may comprise a power limiter to prevent the EM pump tube 5k6 from excessive resistive heating and corresponding elevated temperature in the case that the EM pump tube resistance increases excessively due to low molten metal filling and flow.


In an embodiment, the inlet riser openings may comprise a protection such as an entrance guard for particles such as carbon or metal oxide particles that may block the openings or clog at least one of the inlet riser and the EM pump tube 5k6. In an exemplary embodiment, the inlet riser openings span about 1 cm at the top of the inlet riser tube wherein the desired top molten metal level is at the top of the last opening and the smallest opening is slightly larger than the largest corrosion product while providing restriction to flow relative to the unrestricted EM pumping rate.


Each EM pump may be powered by an independent power supply. Alternatively, the plurality of EM pumps such as two EM pumps may be powered by a common power supply through parallel electrical connections. The current of each pump may be controlled by a current regulator of each parallel circuit. Each parallel circuit may comprise isolation diodes to cause each circuit to be electrically isolated.

In an embodiment, the hydrino reaction conditions in the reaction cell chamber 5b31 may provide and maintain a suitable MHD nozzle 307 temperature and pressure such that the nozzle may produce a high velocity jet while avoiding condensation shock. At least one of about a constant velocity condition and continuity condition whereby the product of the density, velocity, and area is about constant may be maintained during the expansion in the MHD channel 308. In an embodiment, supersonic silver vapor is injected at the entrance to the MHD channel 308 from the MHD nozzle 307. Some silver may condense in the channel, but due to the isentropic expansion, the condensation may be limited. Remaining energy in the jet comprising vapor and any condensed liquid as well as the heat of vaporization of the silver may be by at least partially recovered by condensation at the condenser 309 and recirculation by a recirculator or regenerator such as a heat pipe. In an embodiment, regeneration is achieved using a heat pipe whereby the heat pipe recovers at least the silver heat of vaporization and recirculates it such that the recovered heat power is part of the power input to the MHD channel; then this component of power balance is only reduced by the efficiency of the heat pipe. The percentage of the metal vapor that condenses may be insignificant such as in the range of about 1 to 15%. In an embodiment, condensed vapor may be caused to form an aerosol. The reaction cell chamber, nozzle, and MHD channel may contain a gas such as argon that causes the condensing vapor to from an aerosol.

The liquid metal may be recirculated, and the heat of vaporization may be at least partially recovered by the regenerator such as one comprising a heat pipe.


In another embodiment, the vapor may be forced to condense in a desired region such as the nozzle 307 section. The nozzle expansion may be isentropic wherein condensation of a pure gas such as silver vapor is limited to a liquid mole fraction of 50% starting at the critical temperature and critical pressure which for silver are 506.6 MPa and 7480 K, respectively. In an embodiment, this limitation for condensation from expansion of a pressurized vapor may be overcome by means such as at least one of removal of heat such that the entropy may decrease and by pressurizing the condensing region with at least one other gas. The gas pressure may be equal in all portions of the regions in which there is gas continuity such as in the reaction cell chamber 5b31, the nozzle 307, and the MHD channel 308 regions. The MHD converter may further comprise a tank of other gas, a gas pressure gauge, a gas pump, and a gas pressure controller. The at least one other gas pressure may be controlled by the pressure controller.

In an embodiment, the nozzle 307 comprises a condensing jet injector comprising a two-phase jet device in which the molten metal in the liquid state is mixed with its vapor phase, producing a liquid stream with a pressure that is higher than the pressure of either of the two inlet streams. The pressure may be developed in at least one of the reaction cell chamber 5b31 and in the nozzle 307. The nozzle pressure may be converted to stream velocity at the exit of the nozzle 307. In an embodiment, the reaction cell chamber plasma comprises one phase of the jet device. Molten metal from at least one EM pump injector may comprise the other phase of the jet device.

In an embodiment, the molar volume of the condensed vapor is about 50 to 500 times smaller than the corresponding vapor at standard conditions. The condensation of the vapor in the nozzle 307 may cause a decrease in pressure at the exit section of the nozzle. The decreased pressure may result in an increase in velocity of the condensed flow that may comprise at least one of a liquid and aerosol jet. The nozzle may be extended and may be convergent to convert the local pressure into kinetic energy. The channel may comprise a larger cross sectional area than that of the nozzle exit, and may be straight to allow the propagation of the aerosol flow.

The metal vapor condensation may release the metal vapor heat of vaporization that may increase at least one of the temperature and pressure of the aerosol. The corresponding energy and power may contribute to the kinetic energy and power of the aerosol and plasma flow at the exit of the nozzle. The power of the flow may be converted to electricity with an increase in efficiency due to the contribution of the power from the metal vapor heat of vaporization. The MHD converter may comprise a controller of the source of metal aerosol to control at least one of the aerosol flow rate and aerosol mass density.

wherein dHfog is the differential fog enthalpy, Tfog is the fog temperature, Cp is the specific heat capacity of silver at constant pressure, and Tres is the reservoir and the initial fog temperature. Thus, in the case that the mass flow of fog is about 8 times that of the metal vapor, the metal vapor will condense to release its heat of vaporization in the nozzle with the corresponding energy available to be significantly converted to kinetic energy. Given that an exemplary molar volume of the condensed vapor as fog or aerosol is about 50 times smaller than the corresponding vapor, the fog flow need only be about 15% of the total gas/plasma volumetric flow to achieve condensation of the vapor to result in about pure fog or aerosol plasma flow. The flog flow rate may be controlled by controlling the reservoir temperature, the fog source injection rate such as the EM pump rate, and the pressure of the aerosol-forming gas such as oxygen and optionally argon.

The argon atmosphere may be added and maintained at a desired pressure by systems of the disclosure such as an argon tank, line, valve, controller and injector. The injector may be in the condensation section 309 or other appropriate region to avoid silver back flow.

In an embodiment, at least one of the reaction cell chamber 5b31 and the nozzle 307 may comprise a magnetic bottle that may selectively form a plasma jet along the longitudinal axis of the MHD channel 308. The power converter may comprise a magnetic mirror which is a source of a magnetic field gradient in a desired direction of ion flow where the initial parallel velocity of plasma electrons v− increases as the orbital velocity 12, decreases with conservation of energy according to the adiabatic invariant

the linear energy being drawn from that of orbital motion. As the magnetic flux B decreases, the ion cyclotron radius α will increase such that the flux πα2B remains constant. The invariance of the flux linking an orbit is the basis of the mechanism of a “magnetic mirror”. The principle of a magnetic mirror is that charged particles are reflected by regions of strong magnetic fields if the initial velocity is towards the mirror and are ejected from the mirror otherwise. The adiabatic invariance of flux through the orbit of an ion is a means to form a flow of ions along the z-axis with the conversion of v to v such that v>v. Two magnetic mirrors or more may form a magnetic bottle to confine plasma such as that formed in the reaction cell chamber 5b31. Ions created or contained in the bottle in the center region will spiral along the axis, but will be reflected by the magnetic mirrors at each end. The more energetic ions with high components of velocity parallel to a desired axis will escape at the ends of the bottle. The bottle may be more leaky at the MHD channel end. Thus, the bottle may produce an essentially linear flow of ions from the end of the magnetic bottle into the channel entrance of the magnetohydrodynamic converter.


Specifically, the plasma may be magnetized with a magnetic mirror that causes the component of ion motion perpendicular to the direction of the MHD channel or z-axis v|to at least partially convert into to parallel motion v due to the adiabatic invariant

In the case of an electromagnetic magnetic mirror, the magnetic field strength may be adjustable by controlling the electromagnetic current to control the rate at which ions flow from the reaction cell chamber to control the power conversion.

An exemplary MHD volumetric conversion density is about 70 MW/m3 (70 kW/liter).

In an embodiment, the expansion of the working medium is maintained under conditions to assure isentropic flow. In an embodiment, the inlet working medium conditions are selected for the supersonic nozzle expansion that would ensure reversible expansion in the nozzle and a strong driving pressure gradient in the MHD channel. Since saturation, if it occurs in the nozzle, will lead to strong non-equilibrium sub-cooling due to the rapid cooling rate (such as of about 15 K/us) and this may further will trigger condensation shock in the diverging portion of the nozzle, the nozzle inlet conditions may be highly superheated in order that the vapor does not become saturated during the expansion. In an embodiment, condensation shock is to be avoided because it causes irreversibilities that deviates from the desired isentropic flow condition and sharply reduces the nozzle exit velocity, and the resulting highly dense liquid Ag droplets entrained in the vapor flow in the supersonic/diverging part of the nozzle may lead to accelerated erosion of the nozzle surface. In an embodiment wherein the Lorentz force acts adverse to the flow direction such that a weak driving pressure gradient in the MHD channel may lead to reduced volume flow through the system, the nozzle inlet temperature is as high as possible to allow adequate superheat, and the pressure is also moderately high to assure a strong driving pressure gradient in the MHD section downstream of the nozzle. In an exemplary embodiment, the reaction cell chamber 5b31 pressure at the nozzle entrance is about 6 atm, and the plasma temperature is about 4000 K to result in an isentropic expansion and dry vapor exiting the nozzle at about Mach number 1.24 with about 722 m/s velocity and a pressure of more than 2 atm. Lower inlet temperatures are also possible but these may each yield smaller exit velocity and pressure.

In an embodiment, the silver vapor-silver aerosol mixture that exits the MHD nozzle 307 and enters the MHD channel 308 comprises a majority liquid fraction. To achieve the majority liquid fraction at the MHD channel 308 inlet, the mixture may comprise a majority liquid at the entrance to the MHD nozzle 307. The thermal power of the reaction cell chamber 5b31 generated by the hydrino reaction may be majority converted to kinetic energy by the MHD nozzle 307. In an embodiment to achieve the condition that the majority of energy inventory at the exit of the MHD nozzle 307 is kinetic energy, the mixture must be a majority liquid fraction, and the temperature and pressure of the mixture should approach that of the molten metal at its melting point. To convert a larger fraction of the thermal energy inventory of the mixture into kinetic energy, the nozzle area of the diverging section of a converging-diverging MHD nozzle 307 such as a de Laval nozzle must increase. As the thermal energy of the mixture is converted to kinetic energy in the MHD nozzle 307, the temperature of the mixture drops with a concomitant pressure drop. The low-pressure condition corresponds to a low vapor density. The low vapor density decreases the cross section to transfer forward momentum and kinetic energy to the liquid fraction of the mixture. In an embodiment, the nozzle length may be increased to create a longer liquid acceleration time before nozzle exit. In an embodiment, the cross sectional area of the aerosol jet at the MHD nozzle exit may be decreased. The area decrease may be achieved by one or more of at least one focusing magnet, baffles, and other means known in the art. The focused aerosol jet having a decreased area may permit the MHD channel 308 cross sectional area to be smaller. The MHD channel power density may be higher. The MHD magnets 306 may be smaller due to smaller volume of the magnetized channel 308.


In an embodiment, the temperature of the mixture at the entrance of the MHD channel 308 is close to the melting point of the molten metal. In the case of silver, the mixture temperature may be in at least one range of about 965° C. to 2265° C., 1000° C. to 2000° C., 1000° C. to 1900° C., and 1000° C. to 1800° C. In an embodiment, the silver liquid may be recirculated to the reservoirs 5c by the EM pumps 400, 400a, 400b, or 400c to recover at least a portion of the thermal energy in the liquid.


In an embodiment comprising unions comprising ceramic parts and carbon gaskets, the temperature of the recirculated silver may be below at least one of the carbo-reduction temperature of graphite with the ceramic and the failure temperature of the materials of the SunCell® components such as ceramic components. In an exemplary embodiment comprising yttria-stabilized-zirconia parts such as return conduits 310, EM pump tube section of the current loop 405, reservoirs 5c, reaction cell chamber 5b31, MHD nozzle 307, MHD channel 308, and MHD condensation section 309 having at least one carbon-gasketed flange union 407 between ceramic components, the silver temperature is lower than about 1800° C. to 2000° C. The power of the aerosol comprising kinetic energy and thermal energy may be converted to electricity in the MHD channel. The aerosol kinetic energy may be converted to electricity by a liquid MHD mechanism. Some residual thermal power such as that of any vapor of the mixture in the MHD channel 308 may be converted to electricity by the Lorentz force acting on the corresponding vapor. The conversion of thermal energy causes a drop in mixture temperature. The silver vapor pressure may be low corresponding to the low mixture temperature. The MHD channel 308 may be maintained at a low background pressure such as a pressure in at least one range of about 0.001 Torr to 760 Torr, 0.01 Torr to 100 Torr, 0.1 Torr to 10 Torr to prevent the aerosol jet from the nozzle 307 from undergoing shock such as condensation shock or turbulent flow whereby the aerosol creates increased pressure such as back pressure in the MHD channel 308.


In an embodiment, the vapor fraction of the mixture is minimized at the nozzle inlet to reduce it at the nozzle outlet. The vapor fraction may be in at least one range of about 0.01 to 0.3, 0.05 to 0.25, 0.05 to 0.20, 0.05 to 0.15, and 0.05 to 0.1. Given nozzle exemplary inlet parameters of 20 atm pressure, 0 m/s velocity, 3253 K temperature, 0.9 liquid mass fraction of the mixture, sonic velocity 137 m/s, Mach number 0, and 0 kJ/kg kinetic energy, exemplary parameters of the mixture at the nozzle outlet are about those given in TABLE 3.

In an embodiment, the vapor may be at least partially condensed at the end of the MHD channel such as in the MHD condensation section 309. The heat exchanger 316 may remove heat to cause the condensation. Alternatively, the vapor pressure may be sufficiently low that the MHD efficiency is increased by not condensing the vapor wherein the vapor maintains a static equilibrium pressure in the MHD channel 308. In an embodiment, the Lorentz force is greater than the collision frictional force of any uncondensed vapor in the MHD channel 308. The Lorentz force may be increased to that desired by increasing the magnetic field strength. The magnetic flux of the MHD magnets 306 may be increased. In an embodiment, the magnetic flux may be in at least one range of about 0.01 T to 15 T, 0.05 T to 10 T, 0.1 T to 5 T, 0.1 T to 2 T, and 0.1 T to 1 T. In an embodiment, the silver vapor is condensed such that the heat of vaporization heats the silver that is recycled to the reservoirs or the EM pump tube of a two-stage EM pump wherein the output is the injector 5k61. The vapor may be compressed with compressor 312a. The compressor may be connected to a two-stage EM pump such as 400c.


In an embodiment, the silver vapor/aerosol mixture is almost pure liquid plus oxygen at the exit of the MHD nozzle 307. The solubility of oxygen in silver increases as the temperature approaches the melting point wherein the solubility is up to about 40 to 50 volumes of oxygen for volume of silver (FIG. 3). The silver absorbs the oxygen at the MHD channel 308 such as at the exit and both the liquid silver and oxygen are recirculated. The oxygen may be recirculated as gas absorbed in molten silver. In an embodiment, the oxygen is released in the reaction chamber 5b31 to regenerate the cycle. The temperature of the silver above the melting point also serves as a means for recirculation or regeneration of thermal power. The oxygen concentration is optimized to enable a thermodynamic cycle wherein the temperature of the recirculated silver is less than the maximum operating temperature of the SunCell® components such as 1800° C. In an exemplary embodiment, (i) the oxygen pressure in at least one of the reaction cell chamber 5b31 and the MHD nozzle 307 is 1 atm, (ii) the silver at the exit of the MHD channel 308 is almost all liquid such as aerosol, (iii) the oxygen mass flow rate is about 0.3 wt %, and (iv) the temperature at the exit of the MHD channel is about 1000° C. wherein the O2 accelerates the aerosol and then is absorbed by the 1000° C. silver. The liquid silver-oxygen mixture is recirculated to the reaction cell chamber 5b31 wherein the oxygen is released to form a thermodynamic cycle. The requirement of a gas compressor such as 312a and the corresponding parasitic power load may be reduced or eliminated. In an embodiment, the oxygen pressure may be in at least one range of about 0.0001 atm to 1000 atm, 0.01 atm to 100 atm, 0.1 atm to 10 atm, and 0.1 atm to 1 atm. The oxygen may have a higher partial pressure in one cell region such as at least one of the reaction cell chamber 5b31 and the nozzle 307 relative to the MHD channel exit 308. The SunCell® may have a background oxygen partial pressure than may be elevated in one cell region such as at least one of the reaction cell chamber 5b31 and the nozzle 307 relative to the MHD channel exit 308. Due to the much higher heat capacity of oxygen and non-condensability at operating temperature, the MHD nozzle may be reduced in size relative to that of an MHD converter that uses only silver vapor to achieve the aerosol jet acceleration.


The thermodynamic cycle may be optimized to maximize the electrical conversion efficiency. In an embodiment, the mixture kinetic energy is maximized while minimizing the vapor fraction. In an embodiment, the recirculation or regeneration of thermal power is achieved as a function of the temperature of recirculated silver from the exit of the MHD channel 308 to the reaction cell chamber 5b31. The temperature of the recirculated silver may be maintained less than the maximum operating temperature of the SunCell® components such as 1800° C. In another embodiment, the Lorentz force may cool the mixture to at least partially condense the liquid phase wherein the corresponding released heat of vaporization is at least partially transferred to the liquid phase. At least one of the MHD nozzle expansion, MHD channel 308 expansion, and Lorentz force cooling in the MHD channel 308 may lower the temperature of the mixture at one or more of the MHD nozzle 307 exit and the MHD channel 308 below the melting point of silver. The heat released by condensation of the vapor may be absorbed towards the heat of fusion of silver and silver heat capacity with temperature elevation. The silver heated by the heat of vaporization of condensed vapor may be recirculated to regenerate the corresponding thermal power. In another embodiment to raise the efficiency, relatively cold aerosol may be injected into a power conversion component such as the MHD nozzle 307 or the MHD channel 308 by means such as ducting from the reservoir 5c.

Molecular hydrino may comprise a finite £ quantum number corresponding to orbital angular momentum. The electron orbital angular momentum of a plurality of hydrino molecules such as H2(1/4) may phase couple to give rise to permanent magnetization. Ordinarily, the angular momentum and the corresponding magnetic moment averages to zero and there is no net macroscopic or bulk magnetism due to orbital angular momentum. However, molecular hydrino may give rise to non-zero or finite bulk magnetism when the angular momentum magnetic moments of a plurality of molecules interact cooperatively wherein magnetic self assemble may occur. The trigonometric function spatial-temporal dependence Eqs. (1.67, 1.76, 1.77, 2.66-2.71) of Mills GUT transforms to a trigonometric function squared term that does not average to zero. Due to the magnetism, molecular hydrino may be uniquely identified by electron paramagnetic resonance spectroscopy (EPR). Unique EPR nuclear coupling as well as electron nuclear double resonance spectroscopy (ENDOR) signatures due to the reduced electron radius and internuclear distance are further characteristic and uniquely identify molecular hydrino.


Molecular hydrino such as H2(1/4) may have non-zero l and ml quantum numbers corresponding to orbital angular momentum with a corresponding magnetic moment. The magnetic characteristic of molecular hydrino is demonstrated by proton magic angle spinning nuclear magnetic resonance spectroscopy (1H MAS NMR). The presence of molecular hydrino in a solid matrix such as an alkali hydroxide-alkali halide matrix that may further comprise some waters of hydration gives rise to an upfield 1H MAS NMR peak, typically at −4 to −6 ppm due to the molecular hydrinos' paramagnetic matrix effect. A convenient method to produce molecular hydrino in non-zero angular momentum states is by wire detonation in the presence of H2O to serve as the hydrino catalyst and source of H. Wire detonations in an atmosphere comprising water vapor produces magnetic linear chains comprising hydrino hydrogen such as molecular hydrino possessing nonzero l and ml quantum states with metal atoms or ions that may aggregate to forms webs. The self-assembly mechanism may comprise a magnetic ordering or self-assembly mechanism. It is well known that the application of an external magnetic field causes colloidal magnetic nanoparticles such as magnetite (Fe2O3) suspended in a solvent such as toluene to assemble in to linear structures. Due to the small mass and high magnetic moment molecular hydrino magnetically self assembles even in the absence of a magnetic field. In an embodiment to enhance the self-assembly and to control the formation of alternative structures of the hydrino products, an external magnetic field is applied to the hydrino reaction such as the wire detonation. The magnetic field may be applied by placing at least one permanent magnet in the reaction chamber. Alternatively, the detonation wire may comprise a metal that serves as a source of magnetic particles such as magnetite to drive the magnetic self-assembly of molecular hydrino wherein the source may be the wire detonation in water vapor or another source.


In an embodiment, molecular hydrino may comprise a nonzero angular momentum quantum number. The molecular hydrino may be magnetic wherein the magnetism may be due to a nonzero angular momentum quantum number. Due to its intrinsic magnetic moment, molecular hydrino may self assemble into macroaggregates.

In another embodiment, molecular hydrino can assemble into three-dimensional structures such as a cube having H2(1/p) such as H2(1/4) at each of the eight vertices. In an embodiment, eight H2(1/p) molecules such as H2(1/4) molecules are magnetically bound into a cube wherein the center of each molecule is at one of the eight vertices of the cube, and each inter-nuclear axis is parallel to an edge of the cube centered on a vertex. The magnetic alignment is such that the each north and south-pole of each molecular diploe is oppositely oriented with each of its three nearest neighbors of the cube. H16 may serve as a unit or moiety for more complex macrostructures formed by self-assembly. In another embodiment, units of Hs comprising H2(1/p) such as H2(1/4) at each of the four vertices of a square may be added to the cuboid H16 to comprise H16+8n wherein n is an integer. Exemplary additional macroaggregates are H16, H24, and H32. The hydrogen macroaggregate neutrals and ions may combine with other species such as O, OH, C, and N as neutrals or ions. In an embodiment, the resulting structure gives rise to an H16 peak in the time-of-flight secondary ion mass spectrum (ToF-SIMS) wherein fragments may be observed masses corresponding to integer H loss from H16 such as H16, H14, H13, and H12. Due to the mass of H of 1.00794 u, the corresponding +1 or −1 ion peaks have masses of 16.125, 15.119, 14.111, 13.103, 12.095 . . . . The hydrogen macroaggregate ions such as H16 or H16+ may comprise metastables. The hydrogen macroaggregate ions H16 and H16+ having metastable features of broad peaks were observed by ToF-SIMS at 16.125 in the positive and negative spectra. H15 was observed in the negative ToF-SIMS spectrum at 15.119. H24 metastable species H23 and H25 were observed in the positive and negative ToF-SIMS spectra, respectively.


In an embodiment, a molecular hydrino macroaggregate such as H16 or a decomposition product such as H2(1/p) such as H2(1/4) may comprise a magnetic resonance imaging (MM) contrast agent such as spin polarized Xeon. Molecular hydrino may be inhaled and used in MRI imaging due at least one of its NMR active protons that are imaged or its effect on normal protons such as those of water molecules of the body of the imaged person, animal, or object wherein the paramagnetism of molecular hydrino effects at least one of the corresponding NMR shift or a relaxation time such as at least one of T1 and T2. In an embodiment, para form of molecular hydrino may be converted to the NMR active ortho form by spin exchange. The spin exchange may be achieved using a spin exchange agent such as a magnetic species such as magnetite (Fe2O3) particles.

Experimental


The SF-CIHT cell power generation system includes a photovoltaic power converter configured to capture plasma photons generated by the fuel ignition reaction and convert them into useable energy. In some embodiments, high conversion efficiency may be desired. The reactor may expel plasma in multiple directions, e.g., at least two directions, and the radius of the reaction may be on the scale of approximately several millimeters to several meters, for example, from about 1 mm to about 25 cm in radius. Additionally, the spectrum of plasma generated by the ignition of fuel may resemble the spectrum of plasma generated by the sun and/or may include additional short wavelength radiation. FIG. 4 shows an exemplary the absolute spectrum in the 5 nm to 450 nm region of the ignition of a 80 mg shot of silver comprising absorbed H2O from water addition to melted silver as it cooled into shots showing an average optical power of 1.3 MW, essentially all in the ultraviolet and extreme ultraviolet spectral region. The ignition was achieved with a low voltage, high current using a Taylor-Winfield model ND-24-75 spot welder. The voltage drop across the shot was less than 1 V and the current was about 25 kA. The high intensity UV emission had duration of about 1 ms. The control spectrum was flat in the UV region. The radiation of the solid fuel such as at least one of line and blackbody emission may have an intensity in at least one range of about 2 to 200,000 suns, 10 to 100,000 suns, 100 to 75,000 suns. In an embodiment, the inductance of the welder ignition circuit may be increased to increase the current decay time following ignition. The longer decay time may maintain the hydrino plasma reaction to increase the energy production.


The UV and EUV spectrum may be converted to blackbody radiation. The conversion may be achieved by causing the cell atmosphere to be optically thick for the propagation of at least one of UV and EUV photons. The optical thickness may be increased by causing metal such as the fuel metal to vaporize in the cell. The optically thick plasma may comprise a blackbody. The blackbody temperature may be high due to the extraordinarily high power density capacity of the hydrino reaction and the high energy of the photons emitted by the hydrino reaction. The spectrum (100 nm to 500 nm region with a cutoff at 180 nm due to the sapphire spectrometer window) of the ignition of molten silver pumped into W electrodes in atmospheric argon with an ambient H2O vapor pressure of about 1 Torr is shown in FIG. 5. The source of electrical power 2 comprised two sets of two capacitors in series (Maxwell Technologies K2 Ultracapacitor 2.85V/3400F) that were connected in parallel to provide about 5 to 6 V and 300 A of constant current with superimposed current pulses to 5kA at frequency of about 1 kHz to 2 kHz. The average input power to the W electrodes (1 cm×4 cm) was about 75 W. The initial UV line emission transitioned to 5000K blackbody radiation when the atmosphere became optically thick to the UV radiation with the vaporization of the silver by the hydrino reaction power. The power density of a 5000K blackbody radiator with an emissivity of vaporized silver of 0.15 is 5.3 MW/m2. The area of the observed plasma was about 1 m2. The blackbody radiation may heat a component of the cell 26 such as top cover 5b4 that may serve as a blackbody radiator to the PV converter 26a in a thermophotovoltaic embodiment of the disclosure.


An exemplary test of a melt comprising a source of oxygen comprised the ignition an 80 mg silver/1 wt % borax anhydrate shot in an argon/5 mole % H2 atmosphere with the optical power determined by absolute spectroscopy. Using a welder (Acme 75 KVA spot welder) to apply a high current of about 12 kA at a voltage drop of about 1 V 250 kW of power was observed for duration of about 1 ms. In another exemplary test of a melt comprising a source of oxygen comprised the ignition an 80 mg silver/2 mol % Na2O anhydrate shot in an argon/5 mole % H2 atmosphere with the optical power determined by absolute spectroscopy. Using a welder (Acme 75 KVA spot welder) to apply a high current of about 12 kA at a voltage drop of about 1 V 370 kW of power was observed for duration of about 1 ms. In another exemplary test of a melt comprising a source of oxygen comprised the ignition an 80 mg silver/2 mol % Li2O anhydrate shot in an argon/5 mole % H2 atmosphere with the optical power determined by absolute spectroscopy. Using a welder (Acme 75 KVA spot welder) to apply a high current of about 12 kA at a voltage drop of about 1 V 500 kW of power was observed for duration of about 1 ms.


Based on the size of the plasma recorded with an Edgertronics high-speed video camera, the hydrino reaction and power depends on the reaction volume. The volume may need to be a minimum for optimization of the reaction power and energy such as about 0.5 to 10 liters for the ignition of a shot of about 30 to 100 mg such as a silver shot and a source of H and HOH catalyst such as hydration. From the shot ignition, the hydrino reaction rate is high at very high silver pressure. In an embodiment, the hydrino reaction may have high kinetics with the high plasma pressure. Based on high-speed spectroscopic and Edgertronics data, the hydrino reaction rate is highest at the initiation when the plasma volume is the lowest and the Ag vapor pressure is the highest. The 1 mm diameter Ag shot ignites when molten (T=1235 K). The initial volume for the 80 mg (7.4×10−4 moles) shot is 5.2×10−7 liters. The corresponding maximum pressure is about 1.4×105 atm. In an exemplary embodiment, the reaction was observed to expand at about sound speed (343 m/s) for the reaction duration of about 0.5 ms. The final radius was about 17 cm. The final volume without any backpressure was about 20 liters. The final Ag partial pressure was about 3.7E-3 atm. Since the reaction may have higher kinetics at higher pressure, the reaction rate may be increased by electrode confinement by applying electrode pressure and allowing the plasma to expand perpendicular to the inter-electrode axis.


The power released by the hydrino reaction caused by the addition of one mole % or 0.5 mole % bismuth oxide to molten silver injected into ignition electrodes of a SunCell® at 2.5 ml/s in the presence of a 97% argon/3% hydrogen atmosphere was measured. The relative change in slope of the temporal reaction cell water coolant temperature before and after the addition of the hydrino reaction power contribution corresponding to the oxide addition was multiplied by the constant initial input power that served as an internal standard. For duplicate runs, the total cell output powers with the hydrino power contribution following oxygen source addition were determined by the products of the ratios of the slopes of the temporal coolant temperature responses of 97, 119, 15, 538, 181, 54, and 27 corresponding to total input powers of 7540 W, 8300 W, 8400 W, 9700 W, 8660 W, 8020 W, and 10,450 W. The thermal burst powers were 731,000 W, 987,700 W, 126,000 W, 5,220,000 W, 1,567,000 W, 433,100 W, and 282,150 W, respectively.

The relative change in slope of the temporal reaction cell water coolant temperature before and after the addition of the hydrino reaction power contribution corresponding to the oxide addition was multiplied by the constant initial input power that served as an internal standard. For duplicate runs, the total cell output powers with the hydrino power contribution following oxygen source addition were determined by the products of the ratios of the slopes of the temporal coolant temperature responses of 497, 200, and 26 corresponding to total input powers of 6420 W, 9000 W, and 8790 W. The thermal burst powers were 3.2 MW, 1.8 MW, and 230,000 W, respectively.


In an exemplary embodiment, the ignition current was ramped from about 0 A to 2000 A corresponding to a voltage increase from about 0 V to 1 V in about 0.5, at which voltage the plasma ignited. The voltage is then increased as a step to about 16 V and held for about 0.25 s wherein about 1 kA flowed through the melt and 1.5 kA flowed in series through the bulk of the plasma through another ground loop other than the electrode 8. With an input power of about 25 kW to a SunCell® comprising Ag (0.5 mole % LiVO3) and argon-H2 (3%) at a flow rate of 9 liters/s, the power output was over 1 MW. The ignition sequence repeated at about 1.3 Hz.

The wire may comprise a Mo (molybdenum gauze, 20 mesh from 0.305 mm diameter wire, 99.95%, Alpha Aesar), Zn (0.25 mm diameter, 99.993%, Alpha Aesar), Fe—Cr—Al alloy (73%-22%-4.8%, 31 gauge, 0.226 mm diameter, KD Cr—Al—Fe alloy wire Part No #1231201848, Hyndman Industrial Products Inc.), or Ti (0.25 mm diameter, 99.99%, Alpha Aesar) wire. In an exemplary run, the chamber contained air comprising about 20 Torr of water vapor. The high voltage DC power supply was turned off before closing the trigger switch.

Rotational lines were observed in the 145-300 nm region from atmospheric pressure argon plasmas comprising about 100 mTorr water vapor excited by a 12 keV to 16 keV electron-beam incident the gas in a chamber through a silicon nitride window. The emission was observed through MgF2 another window of the reaction gas chamber. The energy spacing of 42 times that of hydrogen established the internuclear distance as 1/4 that of H2 and identified H2(1/4) (Eqs. (29-31)). The series matched the P branch of H2(1/4) for the H2(1/4) vibrational transition v=1→v=0 comprising P(1), P(2), P(3), P(4), P(5), and P(6) that were observed at 154.94, 159.74, 165.54, 171.24, 178.14, and 183.14 nm, respectively.

The rotational vibrational spectrum may be observed by electron beam excitation of the getter in vacuum. The electron beam energy may be in the range of about 1 keV to 100 keV. The rotational energy spacing between peaks may be given by Eq. (30). The vibrational energy given by Eq.

The beam was incident the compound in vacuum. The zinc hydrino hydride was formed by zinc wire detonation in the presence of water vapor in air according to the methods of the disclosure. The energy spacing of 42 times that of hydrogen established the internuclear distance as 1/4 that of H2 and identified H2(1/4) (Eqs. (29-31)). The series matched the P branch of H2(1/4) for the H2(1/4) vibrational transition v=1→v=0 comprising P(1), P(2), P(3), P(4), P(5), P(6), and P(7).
