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(l/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

91.2

continuum bands with short wavelength cutoffs and energies of m² · 13.6 eV —— nm In m

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 H₂0 is 81.6 eV. Then, by the same mechanism, the nascent

H₂0 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(l / 4) with an energy release of 204 eV, comprising an 81.6 eV transfer to ΗΟΗ and a release of continuum radiation with a cutoff at 10.1 nm (122.4 eV).

In the H -atom catalyst reaction involving a transition to the H ^aH state, m

p = m + 1

H atoms serve as a catalyst of m · 27.2 eV for another (m + 1 )th Η atom. Then, the reaction between m + 1 hydrogen atoms whereby m atoms resonantly and nonradiatively accept m · 27.2 eV from the (m + l )th hydrogen atom such that mH serves as the catalyst is given by

a.

H →H + [[m + \) - 1²] · 13.6 eV - m - 212 eV

And, the overall reaction is

The catalysis reaction [m = 3) regarding the potential energy of nascent H₂0 [1] is a,

2H + 0^~ + e-→Η_Ί 0 + 81.6

And, the overall reaction is

a.

H[a_H ]→H + 81.6 eV + l22A eV

After the energy transfer to the catalyst (Eqs. (1) and (5)), an intermediate

H is formed having the radius of the H atom and a central field of m + 1 times the m + \

central field of a proton. The radius is predicted to decrease as the electron undergoes acceleration to a stable state having a radius of l/(m + 1) the radius of the uncatalyzed hydrogen atom, with the release of m^2■ 13.6 eV of energy. The extreme-ultraviolet

predicted to have a short wavelength cutoff and energy E given by

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(l/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 emission. Greater than 50 eV Balmer 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, HC1, and NaH, OH, SH, SeH, nascent H₂0, 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. That is, in the formula for the principal energy levels of the hydrogen atom: n πε o a H„ n

« = 1,2,3,... (11) where a_H is the Bohr radius for the hydrogen atom (52.947 pm), e is the magnitude of the charge of the electron, and £_o is the vacuum permittivity, fractional quantum numbers:

« = 1,— — — ; where p≤ 137 is an integer (12) 2 3 4 p

replace the well known parameter n = integer in the Rydberg equation for hydrogen excited states and represent lower-energy-state hydrogen atoms called "hydrinos." The n = 1 state of hydrogen and the n =— -— states of hydrogen are nonradiative, but a transition between

integer

two nonradiative states, say n = \ to « = 1 / 2 , is possible via a nonradiative energy transfer. 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

^/· =— , (13) P

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

a

atom in the normal n = 1 state, and the radius transitions to— -— . Hydrinos are formed by m + p

reacting an ordinary hydrogen atom with a suitable catalyst having a net enthalpy of reaction of

m - 212 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

The catalyst product, H\ l l p] , may also react with an electron to form a hydrino hydride ion H (l l p^j , or two H(l / p^j may react to form the corresponding molecular hydrino H₂ (l / p^j . Specifically, the catalyst product, H(l / p^j , may also react with an electron to form a novel hydride ion H (l / p) with a binding energy E_B :

where p = integer > 1 , 5 = 1 / 2 , is Planck's constant bar, μ_ο is the permeability of vacuum, m is the mass of the electron, μ is the reduced electron mass given by

m m P where m is the mass of the proton, a_g is the Bohr radius, and the ionic

radius is r, =— l + . 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).

Upfi eld-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.

where the first term applies to H^~ with p = 1 and p = integer >1 for H (l I p and a 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 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.

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 ^lH nuclear magnetic resonance spectroscopy (MAS ^lH NMR).

H(\ I p may react with a proton and two H(\ I p may react to form H₂ (\ I p and H₂ (l / p^j , respectively.

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.

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 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 change in at least one of resistance, current, voltage, and power of the EM pump power supply 5kl3 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.

Charge separation based on the formation of a mass flow of ions or an electrically conductive medium in a crossed magnetic field is well known art as magnetohydrodynamic (MHD) power conversion. The positive and negative ions undergo Lorentzian direction in opposite directions and are received at corresponding MHD electrode to affect a voltage between them. The typical MHD method to form a mass flow of ions is to expand a high- pressure gas seeded with ions through a nozzle to create high-speed flow through the crossed magnetic field with a set of MHD electrodes crossed with respect to the deflecting field to receive the deflected ions. In an embodiment, the pressure is typically greater than atmospheric, and the directional mass flow may be achieved by hydrino reaction to form plasma and highly conductive, high-pressure-and-temperature molten metal vapor that is expanded to create high-velocity flow through a cross magnetic field section of the MHD converter.

The flow velocity may be increased by a channel geometry that exploits the Venturi effect or Bernoulli principle. In an embodiment, flowing liquid silver may serve as an aspirator medium for the vapor to cause it to flow in the MHD channel.

In an embodiment, at least one of the MHD channel 308 diameter and volume are reduced as a function of the distance along the flow axis or z-axis of the MHD channel from the nozzle 307 exit to the MHD channel 308 exit. The MHD channel 308 may comprise a channel that converges alone the z-axis. In another embodiment, the channel size along the z-axis remains the same or diverges less than that of a conventional seeded-gas MHD working medium converter. The channel volume may be reduced to maintain pressure and velocity along the z-axis as the silver condenses and releases heat to maintain energetic plasma. The heat of vaporization released from condensing silver vapor (254 kJ/mole) with plasma flow along the z-axis may increase the temperature and pressure of the working medium to cause increased flow of the non-condensed silver at any given position along the z-axis of the channel. The increase in flow velocity may be caused by the Venturi effect or Bernoulli principle.

The mixture comprising the working medium may flow under pressure such as 25 atm through a tapered MHD channel wherein the pressure and temperature drop as the thermal energy is converted into electricity. As the temperature drops, the molten metal such as silver may absorb the gas such as oxygen. Then, the liquid may be pumped back to the reservoir to be recycled in the reaction cell chamber wherein the plasma heating releases the oxygen to increase the maintain the desired reaction cell chamber pressure and temperature condition to drive the MHD conversion.

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.

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 entropy decrease to cause condensation of the silver vapor during otherwise isentropic expansion can be estimated by the entropy of vaporization of silver AS given by

AS = ^ = ^{254 kJ / m}°^l = 104 J mole ^ (46)

vap

wherein T is the silver boiling point and AH is the silver enthalpy of vaporization. In the case that silver vapor contacts silver fog or aerosol having the exemplary temperature of the reservoir of 1500 K, the entropy change to reach the boiling point is

t dH_{f r} C dT T

AS fi,g = J f— J¹ J \^ J¹— = C P ln^ J¹ - fog fog res (47)

= 25.4 J mole ^lK ^l ln ^2435K = 123 J mole ^lK ^l

1500^

wherein dH ^' is the differential fog enthalpy, T_f is the fog temperature, C is the specific heat capacity of silver at constant pressure, and T 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 injector may be in the condensation section 309 or other appropriate region to avoid silver back flow. In an embodiment, the super heated silver vapor may be condensed to form an aerosol jet by the injection of silver directly or indirectly into the nozzle.

An exemplary lower temperature and pressure are about 2500 K and about 1 atm, versus 3500 K and 10 atm, respectively.

In the case that the flow velocity decreases, the density of the fog may increase to maintain constant flow in the channel. The density may increase by aggregation of silver fog droplets.

In an embodiment, the differential Lorentz force dF_L is proportional to the silver plasma flow velocity and the differential distance dx along the MHD channel 308:

dF_L = ovB² (\ - W)d²dx

The differential Lorentz force (Eq. (54)) can be rearranged as

wherein (i) the conductivity σ and the magnetic flux B may be constant along the channel, (ii) ideally there is no mass loss along the channel such that the mass m is a constant with respect to distance and the mass flow rate in the channel m is constant due to a constant rate of injection into the channel entrance and continuity of flow under steady state conditions,

condition. The constant mass flow rate with decreasing velocity along the channel may correspond to increasing aggregation of aerosol particles to the limit of complete liquefaction at the MHD channel exit. Then, the rate of change in velocity with respect to channel distance is proportional to the velocity:

£ = Hb- (57) dx

wherein k is a constant determined by the boundary conditions. Integration of Eq. (57) gives v = v₀«T^fa (58)

From Eq. (49), the corresponding power of the channel is given by

In the case that the mass flow m is 0.5 kg/s, the conductivity σ is 50,000 S/m, the velocity is 1200 m/s, the magnetic flux B is 0.1 T, the load factor W is 0.7, the channel width and the electrode separation d of the exemplary straight square rectangular channel is 0.1 m, and the channel length L is 0.25 m, the powers and efficiency are:

P input = 360 kW (62)

P electric = 196 kW (63) and

77 = 54 % (64)

Eq. (64) corresponds to 54% of the initial channel kinetic energy converted to electricity to power an external load and 46% of the power dissipated in the internal resistance wherein the electrical power density is 80 kW/liter.

The electrical power converges to the kinetic energy power input to the MHD channel 0.5mv_Q ² times the loading factor W of the MHD channel. The power density may be

increased by increasing the input kinetic energy power and by decreasing the channel dimensions. The latter may be achieved by increasing at least one of the mass flow rate, the magnetic flux density, and the flow conductivity. In the case that the mass flow m is 2 kg/s, the conductivity σ is 500,000 S/m, the velocity is 1500 m/s, the magnetic flux B is 1 T, the load factor W is 0.7, the channel width and the electrode separation d of the exemplary straight square rectangular channel is 0.05 m, and the channel length L is 0.1 m, the powers and efficiency are:

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 v_± decreases with

v , ²

conservation of energy according to the adiabatic invariant— = constant , the linear energy

B

being drawn from that of orbital motion. As the magnetic flux B decreases, the ion cyclotron radius a will increase such that the flux m²B 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_L . 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 v , ²

— = constant . The ions have a preferential velocity along the z-axis and propagate into the B

magnetohydrodynamic power converter wherein Lorentzian deflected ions form a voltage at electrodes crossed with the corresponding transverse deflecting field. The voltage may drive a current through an electrical load. In an embodiment, the magnetic mirror comprises an electromagnet or a permanent magnet that produces the field equivalent to a Helmholtz coil or a solenoid. 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. In the case that

An exemplary MHD volumetric conversion density is about 70 MW/m³ (70 kW/liter). Most of the problems with historical MHD originate from the low conductivity feature in the gas-fired case and in the low conductivity plus slagging environments in the coal -fired counterpart. The conductivity of the silver SunCell® plasma is estimated to he about 1 m Ω from the current of 10,000 A at a voltage of 12 V. From the arc dimensions, the

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 another embodiment, the ignition system comprises an induction system

(FIGURES 21186, 2I189-2I195) wherein the source of electricity applied to the conductive molten metal to cause ignition of the hydrino reaction provides an induction current, voltage, and power.

The current loop may comprise the intersecting molten metal streams, the injector tubes 5k61, a column of molten metal in the reservoirs 5 c, and the cross connecting channel 414 that connects the reservoirs 5 c at the desired molten silver level or one that is lower than the desired level. The current loop may enclose the transformer yoke 412 that generates the current by Faraday induction. In another embodiment, at least one EM pump transformer yoke 402 may further comprise the induction ignition transformer yoke 412 to generate the induction ignition current by additionally supplying the time-varying magnetic field through an ignition molten metal loop such as the one formed by the intersecting molten metal streams and the molten metal contained in the reservoirs and the cross connecting channel 414. The reservoirs 5c and the channel 414 may comprise an electrical insulator such as a ceramic.

The ceramic of at least one of the reservoirs 5c, the channel 414, and the cover 413 may be one of the disclosure such as silicon nitride (MP 1900 °C), quartz such as fused quartz, alumina, zirconia, magnesia, or hafnia. A protective Si0₂ layer may be formed on silicon nitrite by controlled passive oxidation.

The ceramic parts such as quartz parts may be cast using a mold such as graphite or other refractory inert mold. In an exemplary embodiment, the mold to cast quartz by hot or cold liquid methods known in the art such as that of Hellma Analytics (http://www.hellma- analytics.com/assets/adb/32/32e6a909951dc0e2.pdf) comprises four parts comprising two mirror pairs of inner and outer surfaces of the cell components such as the reservoirs 5c and reaction cell chamber 5b31.

In an embodiment, the cross-connecting channel 414 maintains the reservoir silver levels near constant. The SunCell® may further comprise submerged nozzles 5q of the injector 5k61. The depth of each submerged nozzle and therefore the head pressure through which the injector injects may remain essentially constant due to the about constant molten metal level of each reservoir 5c. In an embodiment comprising the cross-connecting channel 414, inlet riser 5qa may be removed and replaced with a port into the reservoir boss 408 or EM pump reservoir line 416.

At least one of the transformer windings 401 and 411, electromagnets 403, yokes 402, 404, and 412, and magnetic circuits 401a, 403 a, and 410 of at least one of the EM pumps and the ignition system may be shielded from the RF magnetic field of the inductively coupled heater to reduce the heating effect.

In an embodiment, the ignition frequency is adjusted to cause a corresponding frequency of hydrino power generation in a least one of the reaction cell chamber 5b31 and the MHD channel 308. The frequency of the power output such as about 60 Hz AC may be controlled by controlling the ignition frequency. The ignition frequency can be adjusted by varying the frequency of the time-varying magnetic field of the induction ignition

transformer assembly 410. The frequency of the induction ignition transformer assembly 410 may be adjusted by varying the frequency of the current of the induction ignition transformer winding 411 wherein the frequency of the power to the winding 411 may be varied. The time-varying power in the MHD channel 308 may prevent shock formation of the aerosol jet flow. In another embodiment, the time-varying ignition may drive a time-varying hydrino power generation that results in a time-varying electrical power output. The MHD converter may output AC electricity that may also comprise a DC component. The AC component may be used to power at least one winding such as at least one of one or more of the transformer and the electromagnet windings such as at least one of the winidng of the EM pump transformer winding circuit 401a and the winding of the electromagnets of the EM pump electromagnetic circuit 403c.

The pressurized SunCell® having an MHD converter may operate without a dependency on gravity. The EM pumps such as 400 such as two-staged air-cooled EM pumps 400b may be located in a position to optimize at least one of the packing and the minimization of the molten metal inlet and outlet conduits or lines. An exemplary packaging is one wherein the EM pumps are located midway between the end of the MHD condensation section 309 and the base of the reservoirs 5c (FIGURES 2I193-2I195).

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.

TABLE 3. Nozzle Outlet Parameters for Initial Inlet Parameters of Pressure of 20 atm, Li uid Fraction of 0.9 and Mass Flow of 1 k /s.

In an embodiment, the vapor may be at least partially condensed at the end of the MUD channel such as in the MUD condensation section 309. The heat exchanger 316 may remove heat to cause the condensation. Alternatively, the vapor pressure may be sufficiently low that the MUD 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 5T, 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 (FIGURE 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 0₂ 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.

The gasket seal may comprise two flanges sealed with a gasket. The flanges may be drawn together with fasteners such as bolts. The slip nut joint or gasket seal may comprise a carbon gasket. At least one of the nut, the EM pump assembly 5kk, the reservoir base plate 5b8, and the lower hemisphere 5b41 may comprise a material that is resistant to carbonization and carbide formation such and nickel, carbon, and a stainless steel (SS) that is resistant of carbonization such as SS 625 or Haynes 230 SS. The slip nut joint between the EM pump assembly and a ceramic reservoir may comprise an EM pump assembly 5kk comprising a threaded collar and nut comprising a stainless steel (SS) that is resistant of carbonization such as SS 625 or Haynes 230 SS and a graphite gasket wherein the nut threads onto the collar to tighten against that gasket. The flange seal joint between the EM pump assembly 5kk and the reservior 5c may comprise a reservior base plate 5b8 with bolt holes, a ceramic reservoir having a flange with bolt holes, and a carbon gasket. The EM pump assembly having a reservoir base plate may comprise a stainless steel (SS) that is resistant of carbonization such as SS 625 or Haynes 230 SS. The flange of the reservoir may be fastened to the base plate 5b8 by the bolts tightened against the carbon or graphite gasket. In an embodiment, the carbon reduction reaction between carbon such as a carbon gasket a part comprising an oxide such as an oxide reservoir 5c such as a MgO, A1₂0 , or Zr0₂ reservoir is avoided by maintaining the joint comprising oxide in contact with carbon at a non-reactive temperature, one below the carbon reduction reaction temperature. In an embodiment, the MgO carbon reduction reaction temperature is above the range of about 2000 °C to 2300 °C.

In an exemplary embodiment, a ceramic such as an oxide ceramic such as zirconia or alumina may be metalized with an alloy such as Mo-Mn. Two metalized ceramic parts may be joined by braze. A metalized ceramic part and a metal part such as the EM pump bus bars 5k2 may be connected by braze. The metallization may be coated to protect it from oxidation. Exemplary coatings comprise nickel and noble metals in the case of water oxidant, and a noble metal in the case of oxygen. In an exemplary embodiment, an alumina or zirconia EM pump tube 5k6 is metallized at penetrations for the EM pump bus bars 5k2, and the EM pump bus bars 5k2 are connected to the metallized EM pump tube penetrations by braze. In another exemplary embodiment, the parts from the list of at least two of the EM pump assembly 5kk, the EM pump 5ka, the EM pump tube 5k6, the inlet riser 5qa, the injection EM pump tube 5k61, the reservoirs, the MHD nozzle 307, and the MHD channel 308 may be glued together with ceramic glue. Ceramic parts may be fabricated using methods of the disclosure or known in the art. Ceramic parts may be molded, cast, or sintered from powder, or glued together, or threaded together. In an embodiment, the component may be fabricated in green ceramic and sintered. In an exemplary embodiment, alumina parts may be sintered together. In another embodiment, a plurality of parts may be fabricated as green parts, assembled, and sintered together.

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(l/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(l/4) may have non-zero £ and m_i 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 MR). 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 -5 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 H₂0 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 £ and m_i 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 (Fe₂0 ) 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.

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. Hi₆ may serve as a unit or moiety for more complex macrostructures formed by self-assembly. In another embodiment, units of H₈ comprising H₂(l/p) such as H₂(l/4) at each of the four vertices of a square may be added to the cuboid Hi₆ to comprise H₁₆₊₈„ wherein n is an integer. Exemplary additional macroaggregates are Hi₆, 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 Hi₆ peak in the time-of-flight secondary ion mass spectrum (ToF-SIMS) wherein fragments may be observed masses corresponding to integer H loss from Hi₆ such as Hi₆, Hi₄, ¾, and !½. 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 H^~ ₆ or H_l ⁺ ₆ may comprise metastables. The hydrogen macroaggregate ions H^~ ₆ and H_l ⁺ ₆ having metastable features of broad peaks were observed by ToF-SIMS at 16.125 in the positive and negative spectra.

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 (Fe₂0 ) particles. The gas may be incubated with the spin exchange agent to achieve the conversion to ortho form of H₂(l/p). The lifetime of the ortho form in the body may be used as the basis of a MRI contrast agent.

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.

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 X 10^"4 moles) shot is 5.2 X 10^"7 liters. The corresponding maximum pressure is about 1.4 X 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 emission was observed through MgF₂ another window of the reaction gas chamber.
