Definitions

• the present invention relates to the generation of energy, and more particularly to the release of energy as a result of both a state-transition in hydrogen and fusion of light atomic nuclei.
• fusion processes are able to be initiated only at extremely high temperatures, as found in the vicinity of a nuclear fusion (uranium or plutonium) detonation. This is the principle of most thermonuclear bombs. Such a release of energy is impractical as a means of providing the power to generate electricity and heat for distribution, as it occurs too rapidly with too high a magnitude for it to be manageable.
• the present invention provides a method of releasing energy comprising the steps of providing an electrolyte having a catalyst therein, the catalyst being suitable for initiating transitions of hydrogen and/or deuterium atoms in the electrolyte to a sub-ground energy state, and generating a plasma discharge in the electrolyte.
• This method generates substantially more energy than the power input used to generate the plasma, whilst doing so in a controllable manner.
• the plasma discharge is generated by applying a voltage across electrodes in the electrolyte and an intermittent voltage has proved particularly beneficial in increasing the level of energy generation. It also provides a means of controlling the process to maintain a consistent level of energy production over a significant period of time.
• a voltage higher than that necessary to generate plasma is also beneficial to the process and will be typically in the range 50V to 20000V and preferably between 300 and 2000V, but may be higher than 20000V, whereas in conventional electrolysis techniques low voltages of about 3 volts are used and applied continuously across the electrodes.
• the applied voltage may be DC or provided at a switching frequency of up to 100 kHz.
• the duty cycle of the applied voltage is preferably in the range 0.5 to 0.001, but may be even lower than 0.001.
• a monomolecular layer of metal hydride may be formed at the cathode-Helmholtz layer interface and subsequently decays to form gas in the nascent state comprising monatomic hydrogen and/or deuterium.
• the waveform of the applied voltage may be substantially square shaped. Whilst application of DC to the electrode does produce the metal hydride and monatomic hydrogen and/or deuterium, the use of a pulsed voltage has been found to be more efficient as most dissociation of the hydride then occurs between the pulses.
• the electrolyte In applications where the electrolyte is flowed past the electrodes it may be preferable to use two separate cathodes, the first of which will be engineered to optimise production of hydrogen/deuterium atoms and the second of which will provide the plasma discharge. In this instance the direction of flow of the electrolyte is from first to second cathode.
• the design of the apparatus seeks to direct the flow of electrolyte to maximise contact of monatomic hydrogen or deuterium atoms with the plasma .
• the characteristics and magnitudes of the voltages applied to each cathode are preferably similar, but may have different duty periods .
• the cathode design and applied voltage are such as to provide a current density of 400,000 amps per square metre or even greater. More preferably, the current density at the cathode is 500,000 amps per square metre or above.
• the process may be assisted by initial heating of the electrolyte, which may be water or a salt solution, prior to applying electrical input to the vessel.
• the ratio of water to deuterium oxide (D 2 0) in the electrolyte may be varied to control the energy generation. In some circumstances it may be preferable to use "light" water H 2 0 alone and in others to use D 2 0 alone. Additionally, the amount of catalyst added to the electrolyte may be varied as a controlling factor and preferably lies in the range 1 to 20 mMol .
• the method includes the step of generating a magnetic field in the region of the electrodes.
• the intensity and/or frequency of the current used to generate the field may be adjusted to move the plasma discharge away from the electrode from which it is struck in order to minimise erosion and extend the operating life of the system. Only slight separation may be required to achieve this effect.
• the heat generated by the process may be removed and utilised by way of a number of known and proven technologies including the circulation of the electrolyte through a heat exchanger, or using heat pipes to produce heating, or alternatively to produce electricity using a pressurised steam cycle or a low-boiling-point fluid turbine cycle, or by other means.
• the present invention further provides apparatus for carrying out methods disclosed herein comprising an anode, first and second cathodes, a reaction vessel having an inlet and an outlet, means for feeding an electrolyte through the vessel from its inlet to its outlet, the electrolyte having a catalyst therein suitable for initiating transitions of hydrogen and/or deuterium atoms in the electrolyte to a sub-ground energy state, means for applying a voltage across the anode and the first cathode to form hydrogen and/or deuterium atoms, and means for applying a voltage across the anode and second cathode to generate a plasma discharge in the electrolyte, the second cathode being downstream from the first cathode.
• a system comprising a spherical shell of charge (the electron path) located around an atomic nucleus constitutes a resonant cavity.
• Resonant systems act as the repository of photon energy of discrete frequencies .
• the absorbtion of energy by a resonant system excites the system to a higher-energy state.
• the relationship between a permitted radius and the wavelength of the absorbed photon is :
• n is an integer and ⁇ is the wavelength
• ⁇ is the wavelength
• the ground state electron-path radius can be defined as r (0) . This is sometimes referred to as the Bohr radius, a 0 . There is normally no spontaneous photon emission from a ground state atom and thus there must be a balance between the centripetal and the electric forces present.
• n corresponds to a transition which is permitted to occur when a resonant photon is absorbed by the atom.
• Integer values of n represent the absorbtion of energy by the atom.
• Fractional values for n are allowed by the relationship between the standing wavelength of the electron and the radius of the electron-path, given by (2) , above. To maintain force balance, transitions involving fractional values for n must effectively increase the nuclear charge Z to a figure Z eff , and reduce the radius of the electron-path accordingly. This is equivalent to the atom emitting a photon of energy while in the accepted ground state, effecting a transition to a sub-ground state. Because the accepted ground state is a very stable one, such transitions are rarely encountered but the applicants have discovered that they can be induced if the atom is in close proximity to another system which acts as a "receptor-site" for the exact energy quantum required to effect the transition.
• the emission of energy by a hydrogen atom in this way is not limited to a single transition "down" from ground state, but can occur repetitively and, possibly, transitions to 1/3, 1/4, 1/5 etc states may occur as a single event if the energy balance of the atom and the catalytic system is favourable.
• the usual uncertainty principles forbid the determination of the behaviour of any individual atom, but statistical rules govern the properties of any macroscopic (>10 9 quanta) system.
• the radial "ground-state" field can be considered as a superposition of Fourier components. If integral Fourier components of energy equal to m x 27.2 eV are removed, the positive electric field inside the electron path radius increases by
• the resultant electric field is a time-harmonic solution of the Laplace equations in spherical co-ordinates.
• the radius at which force balance and the non-radiative condition are achieved is given by
• the catalytic systems which encourage transitions to sub-ground-state energies are those which offer a near-perfect energy couple to the [m x 27.2] eV needed to "flip" the atom of H or D . It appears from experiment that the effective sink of energy provided by the catalyst need not be precisely equal to that emitted by the atom. Successful transitions have been achieved when there is an error of as much as +_2% between the energy emitted by the atom and that absorbed by the catalytic system.
• One catalyst that has been found to initiate the transition to the a 0 /n state is rubidium in the Rb+ ionic species. If a salt of rubidium, such as the carbonate Rb 2 C0 3 is dissolved in either water or deuterium oxide (heavy water) , a substantial dissociation into Rb + and (C0 3 ) 2 ⁇ ions takes place. If the Rb + ions are bound closely to monatomic H or D, the transition to the a 0 /n state is encouraged by the removal of a further electron from the rubidium ion, by provision of its second ionisation energy of about 27.28 eV.
• the rubidium catalyst remains unchanged in the reaction and there is a net yield of energy per transition.
• catalytic systems which have ionisation energies approximating to [m x 27.2] eV, such as titanium in the form of Ti 2+ ions and potassium in the form of K + ions .
• the Rydberg formula for the frequency of emitted radiation from a transition in monatomic hydrogen is:
• v is the frequency of the emitted photon
• R (h) is Rydberg constant, 1.097373 c 10 7 m _1
• n (1) , n (2) are the transition states
• H or D atoms which may have had significantly diminished electron-path-radii by virtue of exchange of photons with their environment .
• These atoms appear to be relatively unreactive chemically and appear not to readily take the molecular form H-H or D-D. This is a fortunate property which has significance and enables fusion pathways, as described below.
• nuclei may experience a corresponding reduction in electric barrier and internuclear separations may become smaller. With reductions in internuclear separation, fusion processes become more probable, and more easily occasioned.
• the second fusion path is preferred for the peaceful exploitation of its energy yield, because the fusion products are (relatively) harmless on production, and decay to completely innocuous species within a short time, emitting radiation which can be effectively shielded by a thin sheet of kitchen foil or by 10 mm of acrylic plastic, for example.
• the approaching nuclei need to have time to align electrostatically such that the proton-proton separation is at a maximum. This can only be achieved at far lower energies than those found in a thermonuclear bomb.
• fusion can be initiated at lower temperatures (and consequently lower energies) , allowing for the charge-related alignment necessary to achieve a high probability for the second, tritium-forming, pathway.
• deuterium of diminished electron-path- radius into a plasma discharge which is confined within the water in the vessel itself, fusion is may be initiated.
• Temperatures of the order of 6000 K are obtained within certain plasma discharges and this, coupled with multiple quantum transitions to produce deuterium of diminished electron-path-radius, produces a substantial yield of energy from the two-stage process.

It also enables easy calorimetry, safe ducting away of off-gases, and of subsequent extraction of liquid for titration (to demonstrate that no chemical action takes place during the operation of the apparatus) .

It will be seen by the rapid rise in temperature in the apparatus that far more energy is being released than can be accounted for by the electrical input. As a comparison, a heater element can be substituted for the electrodes and operated 1 watt and the effects observed. There is really no need for sophisticated calorimetry to verify that large quantities of energy are being released close to the cathode of the equipment, such is the magnitude of the reaction for the process, as compared to a test with a resistive heating element of the same input power.
