[Industrial Application Field] The present invention relates to a thermal energy output device using a nuclear fusion method that can obtain thermal energy with high efficiency.

As in a recent experiment by S. E. Jones based on [~22l], deuterium generated by applying an electric field between a negative electrode made of Pd or Ti and a positive electrode made of PT in a heavy water electrolyte was There was a method of generating thermal energy associated with nuclear fusion, in which the thermal energy generated when absorbed by the cathode was superimposed (hereinafter referred to as ``electrolytic fusion method''). Recently, Nobuhiko Wada and Kuni have proposed a method in which a hydrogen storage metal (baladium metal) that has sufficiently absorbed deuterium gas is used as a discharge electrode to cause a discharge in deuterium gas, and nuclear fusion is generated within the discharge electrode.

1989pp. L2017-L2020) (hereinafter referred to as "discharge electrode fusion method"). [Problems to be Solved by the Invention] However, when comparing the above two fusion methods, it is found that the discharge electrode fusion method is able to significantly increase the electric field strength near the hydrogen and octogen storage metal electrode than the electrolytic fusion method. Because of this, the kinetic energy of deuterium ions due to the electric field can be increased. This is much more essentially advantageous both for storing deuterium in the hydrogen storage metal electrode and for generating nuclear fusion within the hydrogen storage metal electrode. However, in the conventional discharge electrode fusion method, neutrons generated by nuclear fusion tend to escape outside the hydrogen storage metal electrode, and if the medium in which the hydrogen storage metal electrode is placed is not heavy water (liquid), Since it is hydrogen gas (gaseous), the utilization efficiency of using the generated neutrons to generate thermal energy is extremely low, and there is room for improvement in improving the efficiency of extracting thermal energy by the discharge electrode fusion method. There are still many left. For example, an example of a conventional device that embodies the discharge electrode fusion method is the device shown in FIG. In the figure, 20 is a glass flask, and 2l and 22 are palladium (Pd) electrodes. The flask 20 is filled with deuterium gas, and an alternating current voltage is applied between the electrodes 2l and 22 to generate a discharge, thereby generating nuclear fusion. However, in the conventional device shown in FIG.
It was not possible to extract the heat generated by the The present invention has been made to solve the problems of the prior art described above, and its main purpose is to provide a thermal energy output device using a nuclear fusion method that dramatically improves the efficiency of extracting thermal energy. The goal is to provide the following. Furthermore, it is an object of the present invention to provide a thermal energy output device using the nuclear fusion method, which can be applied to a device that can effectively utilize the extracted thermal energy to generate electrical energy. [Means for Solving the Problems] A fusion heat extraction device that achieves the object of the present invention includes a container for containing deuterium gas, and a pair of containers, at least one of which is made of a hydrogen storage metal, and which is disposed within the container. ), a voltage applying means for applying a voltage between the pair of discharge electrodes to generate a discharge while the deuterium gas is present between them, and a discharge electrode made of the hydrogen storage metal. a heat transfer body for transferring the heat generated by the hydrogen storage metal to the refrigerant; and a kinetic energy heat conversion body for converting the kinetic energy of neutrons generated by nuclear fusion at the discharge electrode made of the hydrogen storage metal into heat. It is characterized by having

[Effect]

The present invention provides a method for generating a discharge by applying a voltage between a pair of discharge electrodes, at least one of which is made of a hydrogen storage metal, and which is disposed in a container in which deuterium gas is stored. By occluding deuterium in the electrode, cold nuclear fusion is generated to generate thermal energy, and the thermal energy is transferred to the refrigerant by the heat transfer body, and the nuclei generated at the discharge electrode made of the hydrogen storage metal are Thermal energy is obtained with high efficiency by converting the kinetic energy of neutrons resulting from fusion into heat using a kinetic energy heat converter. Furthermore, in the present invention, by forming a stronger electric field in the vicinity of the discharge electrode made of the hydrogen storage metal, deuterium can be more efficiently absorbed into the discharge electrode made of the hydrogen storage metal to achieve cold fusion. This can further enhance the reaction. [Specific Description] In the present invention, the hydrogen storage metal constituting at least one of the discharge electrodes may be a single metal or an alloy. For example, C
a. A single metal such as Mg or an alloy containing one of these metals can be used. Also, Ti, Zr, V, Pd. N
A single metal such as B and La or an alloy containing one of these as a composition can be used, for example, T i - M n
alloys such as Ti-Fe-based, La-Ni-based, Mm-Ni
Alloys of the rare earth group including the series L (Mm: mesh metal), alloys of the Pd group, etc. can be usefully used. Hydrogen storage devices for hydrogen storage metals (including alloys) are
Although it varies depending on the type of material (including alloys), the volume of
00-1000 times more hydrogen is absorbed. This approximately corresponds to the volume reduction rate when hydrogen gas is liquefied. Specifically, an example of a hydrogen storage metal is CaMm.
There are N i A 1 alloys, etc. Various studies have been conducted on the activation mechanism of hydrogen (in the following explanation, the term "hydrogen" includes deuterium and tritium, unless otherwise specified) and hydrogen storage metals. , has not yet been fully elucidated.Hydrogen is said to form hydrides with metals or alloys through the following elementary reaction processes: ■Physical adsorption of hydrogen molecules onto the alloy surface, ■Hydrogen molecules dissociation of hydrogen and chemisorption of atomic hydrogen, ■ permeation of hydrogen through surface films, ■ diffusion and dissolution of hydrogen into metals and alloys, ■ precipitation of hydrides from saturated hydrogen individual solutions, etc. Since it exhibits high reactivity with metals or alloys, it can be expected that some kind of catalytic action may exist on the hydrogen storage metal surface. By the way, hydrogen storage metals (including alloys) generally undergo volume expansion as they absorb hydrogen, and this distortion tends to cause them to turn into powder. In order to prevent the electrode made of hydrogen storage metal from turning into powder due to this, it is effective to construct the electrode with a molded solidified product of hydrogen storage metal powder bound with an inorganic material such as Cu or a substance such as silicone rubber. It is. In addition, in order to efficiently penetrate hydrogen atoms (deuterium atoms, tritium atoms) deep into the electrode, a thin layer of hydrogen storage metal having an ultrafine particle structure is coated on the surface of the hydrogen storage metal body.
It is effective in the present invention to use the VD method to make the desired electrode, or to make the desired electrode using the ultrafine particle structure of the hydrogen storage metal itself. In the present invention, the deuterium gas charged between a pair of electrodes disposed in a container containing deuterium gas is generally known to be a good electrical insulator. In addition, in the case of deuterium gas, the higher the pressure, the higher the gas density, but at room temperature, no matter how high the pressure of this gas is, it will not liquefy. Incidentally, the critical pressure and critical temperature, which are the limits of deuterium's liquefaction, are approximately 12.8 atmospheres and approximately -240 degrees, respectively.
In addition, in the present invention, tritium (
In the present invention, in order to form a strong electric field near the discharge electrode made of a hydrogen storage metal, the discharge electrode made of a hydrogen storage metal is That is, the electrode made of the hydrogen storage metal used in the present invention is, for example, a core electrode of a cylindrical electrode structure arranged in concentric circles, or a spherical electrode arranged concentrically. center sphere electrode of the structure,
Alternatively, a needle-like electrode of an electrode structure of a needle-like electrode and a flat plate electrode,
It is preferable to use either the needle electrode of an electrode structure of needle electrodes or the core electrode of a semi-concentric cylindrical electrode structure. The electrode made of the hydrogen storage metal used in the present invention has the shape of 4; 1 selected as above. The electric field in the vicinity can be easily strengthened by Also, deuterium gas is a better electrical insulator than heavy water, which is a liquid, so its electrical insulation breakdown strength is more sufficient than that of heavy water. In the present invention, deuterium cations (.H'') generated by causing an electric discharge in a deuterium gas atmosphere
By being placed in the generated electric field, the hydrogen is attracted to the electrode made of the hydrogen storage metal which serves as the negative electrode, and is occluded in the electrode made of the hydrogen storage metal. At that time, a high voltage is momentarily applied between the electrodes (impact high voltage application),
Producing breakdown between the electrodes is extremely effective in causing nuclear fusion to occur with a higher probability and in further enhancing the nuclear fusion reaction. The theoretical basis for the effectiveness of this method has not yet been clarified. (Although it is only a matter of speculation, this breakdown discharge causes the electrode made of hydrogen storage metal to momentarily become locally hot. In addition, a shock wave, preferably a high-energy shock wave, is applied to the hydrogen storage metal (2) constituting the electrode, and the internal constituent atoms (not only the constituent atoms of the hydrogen storage metal) It is thought that this also applies to the deuterium atoms occluded inside hydrogen storage metals, which instantaneously causes them to violently vibrate, thereby promoting the nuclear fusion reaction. By applying a shock wave to the storage metal electrode, it is easy to generate lattice vacancies and lattice defects caused by interstitial atoms in the hydrogen storage metal, which is used as a negative electrode. As a result, the probability of encounter between deuterium atoms increases, the probability of nuclear fusion occurring increases, and/or the reactivity of nuclear fusion increases.In the present invention, the hydrogen storage metal Shock waves applied to the configured electrodes include, in addition to the shock voltage shown as one of the preferred examples, shock currents, shock waves in the ultrasonic and ultrasonic wavelength ranges, etc. These shock waves , the higher the energy, the more preferable. The waveform of the applied shock wave may be any shape such as rectangular, curved, pulse-like, etc. Also, depending on the type of shock wave, the applied shock wave may be applied only once. Instead, it may be applied to an electrode made of a hydrogen storage metal multiple times at appropriate intervals. In the case of a polarity-dependent shock wave, it may have both positive and negative polarity components. The shock wave that is effectively used in the present invention may be a direct current or an alternating current such as an alternating current. Preferred specific examples include impulse voltage waveforms having a pulse width of about 100 nanoseconds to 600 microseconds. The dielectric breakdown voltage (volts) when a DC voltage is applied across the electrode gap of an electrode structure with spherical electrodes facing each other is
An example of the actually measured value for the product of pressure (torr) and electrode gap length (cm) is shown in FIG. For the refrigerant and neutron kinetic energy heat conversion stage used in the present invention, liquids containing hydrogen atoms as structural atoms are preferably used, and electrically insulating liquids are particularly preferably used. In the present invention, when causing a discharge such as glow discharge, corona discharge, or arc discharge in order to occlude deuterium in a discharge electrode made of a hydrogen storage metal, or in a discharge electrode made of a hydrogen storage metal, When causing a breakdown discharge such as a spark discharge between the discharge electrodes in order to promote the nuclear fusion reaction that occurs, the voltage applied between the discharge electrodes is at least on the discharge electrode side made of a hydrogen storage metal. It is sufficient if the voltage has a polarity phase that is on the cathode side for a certain period of time. For this purpose, instead of a direct current voltage, an alternating voltage or a pulse voltage whose polarity changes alternately may be used. Furthermore, 5
Not only commercial frequency voltage from 0Hz to 60Hz, but also several M
A high frequency voltage of Hz to several hundred Hz may be used. Specifically, the storage body for storing the heavy/hydrogen gas used in the present invention may be, for example, a container made of stainless steel. installed in a physically insulated state.
．． J will be done. The heat transfer body used in the present invention for transferring the heat generated by the discharge electrode made of the hydrogen storage metal to the refrigerant is one end of the discharge electrode made of the hydrogen storage metal or connected to this discharge electrode. One end of a good thermal conductor (heat transfer means) covered with a coolant liquid may be used so that the heat generated by the discharge electrode is transferred to the coolant. At this time, in order to increase the surface area of one end of the discharge electrode that is in contact with the coolant or one end of a good heat conductor (heat transfer means) connected to this discharge electrode and improve heat conduction, one end of these is shaped like a helical shape. The surface area in contact with the coolant may be increased by adding fins or the like. Furthermore, a neutron kinetic energy heat converting means for converting the kinetic energy of neutrons generated by nuclear fusion in the discharge electrode means into heat is placed outside the storage means, and hydrogen atoms, which are likely to decelerate neutrons, are placed outside the storage means. It is sufficient to provide a liquid (neutron moderating liquid) such as water, hydrocarbon liquid, silicone oil, etc. that contains a large amount of water, has a suitably high density, and can be expected to have a cooling effect through convection. A refrigerant for cooling the heat generated by the discharge electrode and a neutron moderator liquid, which is a neutron kinetic energy heat converter that slows down neutrons and converts neutron kinetic energy into heat, are electrically continuous and identical. When using a night body, it is preferable that the liquid be an electrically insulating liquid containing hydrogen atoms as horizontal atoms. [Example 1] In Fig. 1, l is a fusion generation vessel (storage means), 2 is a cylindrical discharge electrode, and 3 is a hydrogen storage device located at the center of the cylindrical discharge electrode 2 where the electric field concentrates. A discharge electrode made of metal, 4 an electrically insulating lid placed so as to close both sides of the cylindrical discharge electrode 2, and 5 a negative voltage applied to the discharge electrode 3 made of at least a hydrogen-absorbing metal with respect to the cylindrical discharge electrode 2. ii, 1 is a power supply for applying a discharge voltage to the cylindrical discharge electrode 2 and the discharge electrode 3 made of a core-shaped hydrogen-absorbing metal so that the phase is applied; 6 is the fusion generation vessel 1;
A vacuum bomb 7 is used to first remove the air inside the fusion generation vessel, and after the air is removed, the inside of the fusion generation vessel l is filled with deuterium gas (10-” Torr to several atmospheres: in this example and below, a large 8, 9. 10 are valves that can be opened and closed, and 1) is a deuterium gas cylinder for use at a pressure level of about 100%. 1) is a valve that can be opened and closed. At least one end of the discharge electrode 3 or one end of a good heat conductor connected to the discharge electrode is provided with a helical heat transfer portion (for heat transfer) to increase the surface area in contact with the coolant and to dissipate heat. (heat transfer means), 12 is a shielded container containing atoms with an atomic number higher than iron for absorbing electric radiation such as gamma rays and accommodating cooling particles and a neutron moderator; l3 is the interior of the shielding container 12; The coolant for cooling the heat transfer part (heat transfer means) 1) of the discharge electrode 3 made of a hydrogen-absorbing metal whose temperature has risen due to heat generation outside the fusion generation vessel and the neutrons released outside the fusion generation vessel l. l4 is a heat exchanger, l5 is a liquid that combines the neutron kinetic energy heat conversion means (neutron moderator liquid) to convert the kinetic energy of
It originally became steam. A water/steam vibrator carries the steam, 16 is a turbine, and 17 is a generator directly connected to the turbine. 1B is a condenser that cools the water used to turn the turbine and returns it to water. In Fig. 1, turbine 1
6. The generator 17 and condensate rock 18 are shown with broken lines to show that these parts are part of the system that could naturally be done using conventional technology, and it actually means that the verification was done without these parts. Do it. A power source 5 connects the discharge electrode 3 made of a hydrogen-absorbing metal.
A negative voltage phase is applied to the cylindrical discharge electrode 2, and the electric field around it is concentrated, so the electric field strength around the discharge electrode 3 is at least as high as the start of ionization discharge (meaning glow discharge/corona discharge). The electric field strength is exceeded. For this reason, heavy hydrogen in the vicinity of the discharge electrode 3 made of a hydrogen-absorbing metal having an ionization discharge starting electric field strength or higher becomes cations, which are drawn to the discharge electrode 3 made of a hydrogen-absorbing metal by the electric field and collected. The collected cations turn into neutral atoms by the discharge electrode 3 and are stored in the discharge electrode 3 made of a hydrogen-absorbing metal. If the discharge current per surface area of the discharge electrode 3 is increased, deuterium is stored in the hydrogen storage metal of the discharge electrode 3 more efficiently per unit time. When a sufficient amount of heavy water is stored in the hydrogen storage metal of the discharge electrode 3, nuclear fusion can occur. Furthermore, if enough deuterium is stored in the hydrogen storage metal of the discharge electrode 3, nuclear fusion can occur although the probability is not very high. Furthermore, after enough deuterium has been stored in the hydrogen storage metal of the discharge electrode 3, or during the storage process, a discharge path is formed spanning between the discharge electrodes 2 and 3, leading to spark discharge or arc discharge. By applying a sufficiently high voltage in a single shot or intermittently and continuously between the discharge electrodes 2 and 3, there is a higher probability than ever that nuclei will form inside the discharge electrode 3 made of a hydrogen-absorbing metal. Fusion can occur. The generated discharge not only instantaneously heats up the hydrogen storage metal electrode locally, but also deuterium sufficiently generates shock waves in the hydrogen storage metal electrode, causing internal atoms (not only the hydrogen storage metal) to become hot. It is thought that the deuterium atoms also violently vibrate instantaneously, making it easier to cause nuclear fusion.Also, by applying an instantaneous high electric field voltage between the two electrodes, a discharge is caused and a breakdown occurs. By causing lattice defects in the hydrogen-absorbing metal, the distance between deuterium atoms in the hydrogen-absorbing metal becomes extremely short.By increasing the encounter probability, nuclear fusion can be generated with high probability. Figure 2 shows the voltage waveform applied to the discharge electrodes 2 and 3 by the power source 5.The voltage waveform shown in the figure is applied to the cylindrical discharge electrode 2 and the discharge electrode made of a hydrogen storage electrode. A voltage was applied so that discharge electrode 3 had negative polarity.The applied voltage waveform was set to a level that did not cause flashover so that a discharge path was formed across discharge electrodes 2 and 3. A sawtooth voltage waveform with a sufficiently high peak voltage is superimposed on a DC voltage that causes local discharge only in the high electric field region near the discharge electrodes 2 and 3 so that a discharge path is formed across the discharge electrodes 2 and 3. A voltage waveform was applied. The cylindrical discharge electrode 2 used was an electrode made of brass with an inner radius of 25 cm. The discharge electrode 3 made of a hydrogen storage metal was a linear palladium (P) electrode with an outer radius of 1 mm.
d). The voltage waveform used, shown in Figure 2, had a DC component of 10 KV and a sawtooth peak voltage value superimposed on this voltage waveform of 55 KV. Also due to fever? A coolant for cooling the heat transfer part 1l outside the fusion vessel of the discharge electrode 3 made of a hydrogen storage metal whose temperature has increased, and a coolant for converting the kinetic energy of neutrons exiting the fusion generation vessel l into heat. , a neutron kinetic energy heat conversion means (neutron moderator), and an electrical resistivity of 10 ohm cm or more (30 V/m).
A normal hexane solution with an electrical resistivity (after applying an electric field strength of m or more for 1 minute or more) was used. As a result of this,
A cylindrical discharge electrode 2 and a discharge electrode 3 made of a hydrogen storage metal
It was possible to apply a sufficient voltage for discharge between the electrodes 23 and the heat transfer section 1) outside the fusion generating vessel, without causing any electrical leakage that would pose a practical problem. This enabled nuclear fusion to occur reliably. In addition, the cooling effect for cooling the heat transfer unit 1) is also due to the neutron kinetic energy heat conversion means (neutron moderating liquid) that converts the kinetic energy of neutrons exiting the fusion generation vessel 1 into heat. The kinetic energy deceleration effect was also fully confirmed. Electrical resistance is 10”Ω instead of normal hexane liquid
・A similar effect was confirmed using silicone oil with a viscosity of 200cs or more. [Example 2] In Example 1, the diameters of the two disc-shaped electrically insulating lids 4 shown in FIG. That is, in contact with the heat transfer part 1),
A coolant (liquid) is used to cool this, and neutron kinetic energy is used to contact the outer surface of the cylindrical discharge electrode 2 and convert the kinetic energy of the neutrons exiting the fusion generation vessel 1 into heat. It was isolated (also electrically isolated) from the heat conversion means (neutron moderator). As a result, the liquid in the shielding container 12 is divided into three parts. These separate liquids were circulated and led to separate and isolated heat exchangers. As a result, the neutrons coming into contact with the heat transfer part (heat transfer means) +1 and coming into contact with the coolant (liquid) for cooling it and the outer surface of the cylindrical discharge electrode 2 and coming out of the fusion generation vessel 1 The same water, which has low electrical resistance, can now be used together with a neutron kinetic energy heat conversion means (neutron moderator) to convert the kinetic energy of neutrons into heat. Water has a high cooling effect, has a large neutron scattering collision cross section, and is highly effective in converting neutron kinetic energy into heat. Moreover, since it is easily available, the effect of using this water is also effective. It goes without saying that the divided water in the shielding container l2 having the same potential as the discharge electrode 3 may be circulated and guided into the same heat exchanger. This effect also provided the same fusion heat extraction effect as in Example 1. [Embodiment 3] FIG. 3 shows an embodiment of a nuclear fusion heat extraction device in which at least one of mutually opposing discharge electrodes is constituted by a plurality of discharge electrodes. In FIG. 3, parts having the same meaning as in FIG. 1 are designated by the same numbers. FIG. 3 will be explained below. l
O1 is a cylindrical electric insulator that constitutes a part of the fusion generation vessel; 104 is a disk-shaped electrically insulating lid that constitutes the fusion generation vessel l together with the cylindrical electric insulator 101; 102;
are discharge electrodes made of rod-shaped brass with a diameter of 3 mm arranged concentrically on a cylindrical electrical insulator 101;
103-5 is a needle-shaped discharge electrode with a diameter of 2 mm and a sharp tip made of baladium (Pd), a hydrogen storage metal.
The distal end thereof is set to be inserted into the cylindrical electric insulator 101 with a gap length of 20 mm between it and the discharge electrode 102 . Moreover, these discharge electrodes 103-1 to 103-5
As shown in the figure, a heat transfer part (fin) 1) for cooling is thermally connected and attached to the part that protrudes from the fusion generation vessel l. Although it is unclear in the figure, this electrode 103
The electrical terminals -1 to 103-5 are exposed outside the shielding container 12, and each electrical terminal is electrically connected to one end of the power source 5. The other end of the power source 5 is electrically connected to the discharge electrode 102'. The air inside the fusion generation vessel l is removed using the vacuum bomb 6, and then valves 8 and 9 are closed and valve 10 is opened to seal the deuterium in the cylinder 7 containing deuterium gas into the fusion generation vessel l. After that, a discharge electrode 1 made of palladium, a hydrogen storage metal, is
03-1 to +03-5 are charged at least to the discharge electrode 103 so as to cause a weak partial discharge between the discharge electrodes +02 and 103. A voltage such that the voltage has a negative voltage phase with respect to the discharge electrode 102 is applied to the discharge electrodes 102 and 1.
In addition to 03, it absorbs deuterium. Thereafter, a voltage having a voltage waveform as shown in FIG. 2 is applied, although the voltage value is different, to cause nuclear fusion. Discharge electrode + 03- 1-1 03
In order to form a plurality of discharge paths spanning almost simultaneously between the discharge electrode 102 and the other discharge electrode 102, each of the discharge electrodes 103-1 to 103-5 and the discharge electrode It is better to apply a voltage between the IA 102 and the IA 102 from separate power sources (multiple electric IAs 5) in that more nuclear fusion can be generated. A coolant is used to cool the heat transfer part l outside the fusion generation vessel of the discharge electrode 103 made of a hydrogen-absorbing metal whose temperature has increased due to heat generation, and the kinetic energy of the neutrons exiting the fusion generation vessel l is converted into heat. As an electrically insulating liquid having a neutron kinetic energy heat converting means (neutron moderator) for converting neutron kinetic energy, we use an electrically insulating liquid with a viscosity of 200 cs and an electrical resistivity of 101 ohm cm or more (30 V/mm or more). A silicone oil with an electrical resistivity (after applying an electric field strength of 1 minute or more) was used. The voltage waveform used had a DC component of 3.6 kV, and a voltage waveform with a sawtooth tip voltage of 40 kV superimposed thereon. This fusion heat extraction effect was not only sufficiently effective for practical use as in Example 1, but also
A separate power supply Cit! is provided between each of the poles 103-1 to 103-5 and the discharge electrode 102. When a voltage was applied with a plurality of 5>, the amount of nuclear fusion was larger than in Example 1, and the amount of fusion heat extracted also increased. Almost the same amount of nuclear fusion and its readout amount was obtained using just the sawtooth voltage waveform. [Example 4] Instead of the rod-shaped brass discharge electrode 102 of Example 3, a diameter of 3
A bar-shaped discharge electrode 102 made of baladium Pd with a diameter of 1 mm was used. In addition, a separate power supply (a plurality of power supplies 5) is provided between each of the discharge electrodes 103-1 to 103-5 and the discharge electrode 102.
Wiring was done via a discharge resistor so that a voltage could be applied. The voltage waveforms of the plurality of power supplies 5 were AC voltage waveforms of 10 kV and 60 Hz. This voltage is sufficient to form a discharge path spanning between discharge electrode 103 and discharge electrode 102. The discharge electrodes 102 and 103 are left in deuterium gas to sufficiently absorb deuterium into the discharge electrodes 102 and 103, and then this voltage is applied between the electrodes 102 and 103 to generate nuclear fusion. I let it happen. This also increased the amount of fusion heat extracted, probably because the amount of nuclear fusion was greater than that of Example 3. At this time, a fin-shaped heat transfer means 1 was provided at the portion of the electrode 102 where the left side was exposed to the outside of the electrically insulating lid 104. [Example 5] In Example 4, the diameter of the disc-shaped electrically insulating lid 104 on the left side of FIG. 3 (the side where the heat transfer means 1 is provided at the terminal of the electrode 102) is increased This electrically insulating lid 104 was brought into close contact with the inner wall of the shielding container 12. That is, the electrode 102
The respective coolants for cooling in contact with the respective heat transfer parts 1l connected to and 103 are also electrically isolated from each other. That is, this divides the coolant liquid in the shielded container into two parts. These coolant liquids also serve as neutron kinetic energy heat conversion means (neutron moderating liquid) for converting the kinetic energy of neutrons exiting the fusion generating vessel 1 into heat. The liquid in contact with the potential parts of the electrode 102 and the electrode 103 can be electrically isolated by providing an electrical insulator between them, and the same water with low electrical resistance can be used as the liquid. It became so. Water has a high cooling effect and is also highly effective in converting neutron kinetic energy into heat by colliding neutrons with water's hydrogen atoms. Moreover, since it is easily available, the effect of using this water is also effective. It goes without saying that the two divided waters in the shielding container 12 having the same potential as the discharge electrode 3 may be circulated and guided within the same heat exchanger. This effect also provided the same fusion heat extraction effect as in Example 4. [Comparative Example] FIG. 5 shows a conventional discharge electrode fusion method device. In the figure, 20 is a glass flask, 2l and 22 are palladium (Pd) electrodes, the flask 20 is filled with deuterium gas, and an alternating current voltage is applied between the electrodes 2l and 22 to cause a discharge, resulting in nuclear fusion. to occur. However, in this method, it is not possible to simultaneously convert neutrons generated by nuclear fusion into heat and to cool the electrodes 21 and 22 that generate heat and extract it as heat without causing electrical leakage. Ta. [Effects of the Invention] As described above in detail, according to the thermal energy output device using the nuclear fusion method of the present invention, the thermal energy generated by the nuclear fusion method can be extracted with high efficiency.
