Description

[0001]
[Industrial applications]
The present invention relates to a ship such as a cargo ship, a passenger ship, or a submarine.
[0002]
[Prior art]
Internal combustion engines are commonly used as power sources for cargo ships and passenger ships. Many submarines use nuclear power as a power source.
In place of these old power sources, ships using magnetic power as a power source have attracted attention. A ship using magnetic force is equipped with a thrust generator disclosed in, for example, Japanese Patent Application Laid-Open No. 4-133656.
In a ship that applies magnetic force, seawater is drawn into the hull and gives extremely strong magnetic force to the seawater. Then, Lorentz force is generated in the ions in the water, and the seawater itself moves. In ships that apply magnetic force, the movement of this seawater is used as the driving force.
[0003]
[Problems to be solved by the invention]
A ship that applies magnetic force has a strong propulsion force in theory, and is capable of dramatic high-speed cruising compared to a conventional ship.
Also, in recent years, a ship using magnetic force has been prototyped, and it has been demonstrated that the hull moves by magnetic force.
However, although the above-mentioned ship was able to move, its speed was extremely slow.
SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances of ship development, and has as its object to disclose a higher speed and more practical structure of a ship to which magnetic force is applied.
[0004]
[Means for Solving the Problems]
While the prior art ships all generate a propulsion force in the seawater itself by magnetic force, the ship of the present invention uses magnetic force and water. The hull is propelled by this.
That is, the present invention for achieving the above object has a main waterway in which water flows in a hull, an arc generating electrode is provided in the main waterway, and the main waterway or around the main waterway is provided. A capture electrode and a magnet are arranged downstream of the arc generation electrode, an arc discharge is generated in the main channel by the arc generation electrode, a fluid flow generated by the arc discharge is passed through a magnetic field, and a voltage is applied to the capture electrode. The ship is characterized by generating.
[0005]
Another invention for achieving the above object is to generate a propulsive force by arc discharge, and has a water passage communicating with the outside in a part of the hull, and an arc generating electrode is arranged in the water passage. A ship characterized by being made.
[0006]
In addition, the present invention, which is a further improved version of the above two inventions, has a sub-waterway in addition to the main waterway, and the main waterway is annularly connected via the sub-waterway.
[0007]
Here, a water channel switching device is provided in the main water channel or the sub water channel, and both ends of the main water channel can be opened to the outside by the water channel switching device, and the main water channel can be annularly connected via the sub water channel. It is desirable.
[0008]
Further, it is preferable that three or more arc generating electrodes are provided, and a polyphase alternating current is applied to the arc generating electrodes.
However, a direct current may be applied to the arc generating electrode.
[0009]
In addition to the configuration of the above-described invention, a rotating body to which a permanent magnet is attached, and a winding, the rotating body is disposed in a main waterway, and the winding is provided around the main waterway, and a rotation of the rotating body is provided. It is desirable to generate an electromotive force in the winding according to the following.
[0010]
In addition, the rotating body has a permanent magnet provided around it, and a blade is provided inside the permanent magnet, and the angle of attack of the blade with respect to the fluid flow is smaller on the center side of the flow path than on the outside. Is desirable.
[0011]
[Action]
The ship according to the first aspect applies the principle of MHD (Magneto Hidro Dynamics) power generation. Here, MHD power generation is to generate power by moving a conductive fluid in a magnetic field. The power generation device of the present invention utilizes arc discharge for generating ionized gas (plasma).
[0012]
That is, the marine vessel of the present invention has a main waterway through which water flows in the hull, and an arc generating electrode is provided in the main waterway. Then, AC or DC is applied to the arc generating electrode, and an arc discharge occurs in water.
Therefore, the water around the arc electrode evaporates instantaneously, and a part of the water reaches an ionized state. Some of the water becomes water gas, _Two And O _Two Separates and burns violently.
[0013]
The high-temperature gas generated by these passes through the magnetic field created by the magnet, and a voltage is induced in the high-temperature gas. Then, this voltage is taken out by the capture electrodes and a voltage is generated between the capture electrodes.
The ship of the present invention uses the electric power generated by the MHD power generation as a power source and other necessary energy for the ship.
[0014]
In the marine vessel according to the second aspect, part or all of the explosive energy generated by the arc discharge is injected from a part of the hull to generate propulsion.
That is, the marine vessel according to the second aspect has a water channel communicating with the outside, and the arc generating electrode is disposed in the water channel. Because of the arc discharge It is possible to convert part of the water to water gas and burn the water gas, The fluid flow is injected from a part of the hull.
[0015]
In the marine vessel according to the third aspect, since the main waterway is connected in a ring shape with the auxiliary waterway, the fluid flow generated by the arc discharge circulates in the marine vessel. Therefore, power generation is repeatedly performed by the fluid, and much of the energy of the fluid contributes to power generation.
[0016]
The ship according to claim 4 is provided with a waterway switching device, and the main waterway can be switched between an external opening and an annular structure.
Therefore, in the ship of the present invention, it is possible to switch between the case where the fluid energy is used only for power generation and the case where it is used for injection propulsion.
[0017]
In the marine vessel according to the fifth aspect, three or more arc generating electrodes are provided, and a polyphase alternating current is applied to the arc generating electrodes. Therefore, the temperature at which arc discharge occurs is extremely high, and a high temperature of 10,000 K is generated between the electrodes.
Therefore, much of the water is turned into plasma, and stable power generation is performed.
[0018]
According to a seventh aspect of the present invention, in addition to the above-described MHD power generation, or in a vessel having no MHD power generation, a power generation device different from the MHD power generation is provided.
In the marine vessel according to the seventh aspect, the rotating body rotates under the force of the fluid in the main waterway. In the present invention, since the permanent magnet is attached to the rotating body, the permanent magnet rotates in the water channel.
Here, in the ship of the present invention, since the winding is provided around the main waterway, the magnetic field cuts the winding and an electromotive force is generated in the winding.
[0019]
The invention according to claim 8 is an improvement of the invention according to claim 7 described above. In the above-described ship according to claim 7, the rotating body is in the main waterway. Here, the problem is that in each of the ships of the present invention, power is generated by a fluid flow originating at a high temperature generated by an arc-generating electrode, and the speed of the fluid flow is significantly different between a central portion and a peripheral portion of a water channel. .
More specifically, the flow velocity of the fluid is extremely high because gasified gas, vapor, or the like passes through a portion near the central axis of the water channel. On the other hand, since high-temperature water flows on the periphery of the water channel, the flow velocity is relatively slow.
[0020]
For this reason, if the blades of the rotating body are uniform, the rotating body receives energy from the fluid at one part in the radial direction, but on the other part, the rotating body gives energy to the fluid on the contrary.
On the other hand, in the invention according to claim 8, since the angle of attack of the blades of the rotating body with respect to the fluid flow is smaller on the center side of the flow path than on the outside, the rotating body is separated from the fluid at any radial position. Can receive energy.
[0021]

In the drawing, reference numeral 1 denotes a ship according to a specific embodiment of the present invention. In the marine vessel 1 of this embodiment, two rows of main waterways 2 and 3 and a row of subwaterways 5 are provided inside the hull. Each of the main water channels 2 and 3 and the sub water channel 5 is constituted by a pipe having rigidity that can withstand the pressure and temperature in charge. The main waterways 2 and 3 extend from the bow to the stern on both abdominal sides, and both ends are open to the bow or stern.
[0023]
The sub waterway 5 is located between the two main waterways 2 and 3 and, like the main waterways 2 and 3, the bow and stern side are open to the outside.
The bow-side comrades of the main waterways 2 and 3 and the sub-waterway 5 are connected by a crossover waterway 10. Similarly, the main waterways 2 and 3 and the stern side of the auxiliary waterway 5 are connected by a crossover waterway 11.
Gates 6 and 7 are provided at the bow and stern side openings of the main waterways 2 and 3, and the openings of the main waterways 2 and 3 to the outside can be closed. The gates 6 and 7 can close the space between the sub waterway 5 and the crossover waterway 10.
Two gates 12 are provided at the opening on the bow side of the sub waterway 5. The opening on the bow side of the sub waterway 5 can be closed by the gate 12, and the space between the sub waterway 5 and the crossover waterway 10 can be closed.
[0024]
Similarly, two gates 13 are also provided at the stern side opening of the sub waterway 5, and the stern side opening of the sub waterway 5 and the space between the sub waterway 5 and the crossover waterway 11 can be closed.
In the boat 1 of this embodiment, each of the gates 6, 7, 12, 13 functions as a waterway switching device.
The structure of the ship 1 according to the present embodiment is that the MHD power generation unit 16, the steam power generation unit 17, and the water flow power generation unit 18 are respectively provided in series in the main waterways 2 and 3 of the ship 1 according to the embodiment. It is.
[0025]
Explaining one by one, the MHD power generation unit 16 includes an ionized gas generation unit and a power generation unit following the ionized gas generation unit. The ionized gas generating section includes six arc generating electrodes 20 and one fuel gas supply pipe 21. The arc generating electrode 20 is made of a non-consumable electrode such as carbon. The six arc generating electrodes 20 are inserted at equal intervals from the periphery of the main waterways 2 and 3 toward the center as shown in FIG. 3B, and are inclined at a constant angle from the bow to the stern. The tips are arranged in a circle at the center of the main channels 2 and 3. Further, an electrode feeding device (not shown) is provided, and the amount of projection of the arc generating electrode 20 into the main water channels 2 and 3 can be adjusted. That is, although the arc generating electrode 20 is made of a non-consumable electrode, it is exposed to an extremely high temperature, so that it is inevitable that a part of the arc generating electrode 20 will be melted or burned and shortened with time. When the arc-generating electrode 20 is shortened due to combustion or the like, the arc-generating electrode 20 is extended to maintain an interval between the electrodes.
[0026]
The connection state of the arc generating electrodes 20 will be described. The arc generating electrodes 20 employed in the present embodiment are electrically connected as a set of three, as shown in FIG. Are connected to each phase. Each phase voltage is applied to each arc generating electrode 20, so that arc discharge is generated between the respective tips.
[0027]
On the other hand, the fuel gas supply pipe 21 is a double pipe having an outer pipe 25 and a middle pipe 26. The fuel gas supply pipe 21 is inserted from the periphery of the main water channels 2 and 3, and its tip is opened toward the center of a circle formed by the tip of the arc generating electrode 20.
The outer pipe 25 of the fuel gas supply pipe 21 is connected to a flammable gas supply source such as hydrogen gas, methane gas, ethane gas, or the like, or a tank for liquid fuel such as heavy oil or light oil. The type of combustible gas or liquid fuel supplied from the outer pipe 25 is not particularly limited, but among them, hydrogen gas generates water as a result of combustion. desirable.
The middle pipe 26 of the fuel gas supply pipe 21 is connected to an air supply source or an oxygen supply source. The gas supplied from the middle tube 26 can be either air or oxygen, but among them, air, particularly heated air, is recommended. The reason is that if oxygen is directly supplied, the arc generating electrode 20 burns and is consumed.
[0028]
The power generation unit of the MHD power generation unit 16 has six magnets 28 arranged around the main water channels 2 and 3, and a capture electrode 30 is provided between the magnets 28.
Magnetic fields are formed by the magnets 28 in the main water channels 2 and 3 corresponding to the power generation unit of the MHD power generation unit 16.
Here, two magnets 28 are provided around the main channels 2 and 3 as a set as shown in FIG. 4, and the lines of magnetic force cross the main channels 2 and 3 in the vertical direction.
The magnet 28 used in the MHD power generation unit 16 may be a permanent magnet, but it is desirable that the magnetic force be as strong as possible, and the use of an electromagnet or a superconducting magnet is recommended.
[0029]
The downstream side of the MHD power generation unit 16 is continuous with the steam power generation unit 17. In the steam power generation unit 17, a steam turbine is built in the main waterways 2 and 3.
[0030]
Further, the downstream of the steam power generation unit 17 is connected to the water flow power generation unit 18. Here, the configuration of the water flow power generation unit 18 is special.
FIGS. 5 and 6 show the water flow power generation unit 18 employed in this embodiment. The water flow power generation unit 18 has a structure in which a rotating body 32 is disposed in the main water channels 2 and 3, and a winding 33 is provided around the main water channels 2 and 3.
The rotating body 32 has a four-layer structure concentric with respect to the radial direction. In FIG. 5, for ease of understanding, each layer is shown exploded, but in reality, all four layers are integral and rotate integrally as a whole.
[0031]
The rotating body 32 has a thin central axis 40, on which the first blade 41 is provided to form a first layer.
The tip of the blade 41 is integrally covered with a tubular body 43, and a second blade 45 is provided on the surface of the tubular body 43 to form a second layer.
Further, a cylindrical body 46 is put on the tip of the second blade 45, and a third blade 47 is provided on the surface of the cylindrical body 46 to form a third layer.
[0032]
Further, a cylindrical body (not shown) is covered on the tip of the third blade 47. A permanent magnet 50 having a concave cross section is provided on the surface of the cylindrical body. One of the permanent magnets 50 has an N pole, and the other has an S pole. The permanent magnets are arranged such that adjacent protrusions have different poles.
The blades 41, 45, and 47 provided on the first, second, and third layers of the rotating body 32 are provided in a direction that generates a propulsive force in the same rotational direction with respect to the flow of the fluid described below. However, the angles of attack for the fluid flow are all different. Specifically, the first blade 41 has an extremely small angle of attack, and the arrangement of the blades 41 is nearly parallel to the axis. On the other hand, the second and third blades 45 and 47 have a large angle of attack and a large component perpendicular to the axis. Comparing the angles of attack of the blades 45, 47, the outer third blade 47 has a larger angle of attack with respect to the inner second blade 45.
[0033]
The winding 33 is provided outside the main waterways 2 and 3. The winding 33 is constituted by an operation line 52 provided in parallel with the main waterways 2 and 3 and crossovers 51 and 53. That is, in the present embodiment, the winding is a single wire, and the main waterway 2 is formed in a zigzag manner as in the form of an operation line 52, a crossover line 51, an operation line 52, a crossover line 53, an operation line 52,. 3 are arranged around. The interval between the operation lines 52 is equal to the interval between the N pole and the S pole of the permanent magnet 50 of the rotating body 32 described above.
[0034]
In addition, the boat 1 of this embodiment includes two motors 55, and the screw 56 is rotated by the motor 55. A gate 58 is provided at an intermediate portion of the sub waterway 5.
[0035]
Next, the operation of the boat 1 of the present embodiment will be described. When navigating the ship 1 of the present embodiment, all the openings of the main waterways 2 and 3 and the sub-waterway 5 are opened, and each waterway is cut off to make three independent waterways.
More specifically, the gates 6 and 7 are operated to open the bow and stern end portions of the main waterways 2 and 3 to the outside. Gates 6 and 7 also close the boundaries between crossing waterways 10 and 11 and main waterways 2 and 3.
Similarly, the bow and stern side ends of the sub waterway 5 are opened to the outside by the gates 12 and 13, and at the same time, the boundaries with the crossover waterways 10 and 11 are closed.
[0036]
In this state, power is supplied to the arc generating electrodes 20 from the three-phase AC power supply 60 shown in FIG. 3B, and an arc discharge is generated between the arc generating electrodes 20. Further, the fuel gas and the air are discharged from the fuel gas supply pipe 21 toward the arc discharge together with the energization of the arc generating electrode 20.
Incidentally, when the arc generating electrode 20 is energized from a three-phase AC power supply as employed in the present embodiment, the arc discharge is generated simultaneously with energizing the arc generating electrode 20. Therefore, the start-up of the device is easy and automation is also possible.
In the ship 1 of the present embodiment, since the three-phase alternating current is supplied to the arc generating electrode 20, the total current of each phase is always 0, the earth wire is unnecessary, and the arc discharge does not require the counter electrode. It will be portable. Therefore, the seawater around the arc generating electrode 20 is directly heated by the arc discharge. That is, according to the ship 1 of the present embodiment, seawater is heated with extremely high efficiency.
[0037]
Further, the temperature of the arc discharge reaches 4000K to 10000K, the surrounding seawater evaporates immediately, and further becomes water gas, and hydrogen is separated into water and oxygen gas. On the other hand, it should be noted that seawater heated by arc discharge generated from six electrodes using three-phase alternating current as a power source, as employed in the present embodiment, is compared with the case of normal electrolysis. It is separated into hydrogen gas and oxygen gas in several stages.
The reason is that considerable current and voltage are applied to the seawater by the arc-generating electrode 20, so that the surrounding seawater is exposed to an extremely high temperature by the arc discharge in addition to increasing the decomposition ability. It is considered that a large amount of seawater is decomposed due to the synergistic effect of the two.
[0038]
Further, since a large amount of ultraviolet rays and light waves are generated by the arc discharge, it is expected that decomposition of seawater is promoted by these actions. Further, in the present embodiment, since an arc discharge is generated by the three-phase alternating current, a rotating magnetic field is generated at the tip of the arc generating electrode 20 and electromagnetic vibration is induced. Therefore, the decomposition of seawater is also promoted by the electromagnetic vibration. It is assumed that there is.
In addition, when liquid seawater is rapidly heated by Joule heat generated by an electric current or arc discharge, rapid thermal expansion of the seawater occurs, and a violent bombing similar to thunder is generated. As a result, intense shock waves are generated at the same time. This shock wave is also expected to contribute to seawater decomposition.
[0039]
A part of the hydrogen gas and the oxygen gas generated by the above action is burned, and in addition to this combustion, the combustion gas discharged from the fuel gas supply pipe 21 is combined with the oxygen in the supplied air to burn. I do. Therefore, an extremely large amount of heat is generated at the tip of the arc generating electrode 20 and on the downstream side thereof. Then, the steam is ionized and gasified by receiving the heat.
On the other hand, since seawater exists around the arc-generating electrode 20, the arc-generating electrode 20 itself is cooled and has little melting.
[0040]
The ionized vaporized water vapor 61 flows at high speed through the central portions of the main water channels 2 and 3 as shown in FIGS. Then, the ionized vaporized water vapor 61 traverses the magnetic field formed by the magnet 28, causes the decomposition of electric charges, and generates an electromotive force. The electromotive force is taken out by the capture electrode 30 and generates a voltage between the capture electrodes 30.
[0041]
It should be noted that in the ship 1 of the present embodiment, since seawater exists in the main waterways 2 and 3, the surrounding seawater (liquid) or the ionized gas Water vapor that does not lead to gas migration moves. That is, in the marine vessel 1 of the present embodiment, as shown in FIG. 3, a gas or liquid layer 62 having a low temperature exists around a gas flowing in high temperature and high speed in an ionized gas state. Therefore, although the central portions of the main waterways 2 and 3 have high temperatures, the peripheral portions have relatively low temperatures.
Therefore, the temperature rise of the capture electrode 30 is suppressed, and the melting of the capture electrode 30 is prevented.
[0042]
The ionized gasified water vapor is deprived of energy required for power generation when passing through the MHD power generation unit 16. The ionized gasified water vapor mixes with the surrounding water vapor or liquid seawater as the distance from the arc generating electrode 20 increases, and gradually homogenizes.
That is, heat exchange is smoothly performed between the ionized gasified steam, normal steam and liquid seawater, and a large amount of steam is generated. After leaving the MHD power generation unit 16 for a while, the fluid in the main waterways 2 and 3 is filled with steam.
The steam enters the steam power generation unit 17 and generates power by rotating a turbine (not shown).
[0043]
The fluid that has exited the steam power generation unit 17 enters the water flow power generation unit 18.
The fluid that has reached the water flow power generation unit 18 has lost most of the energy and is mostly hot water. However, there is a slight layer of water vapor in the center of the flow, and the flow velocity in the center is high. In addition, there is a layer around which water and water vapor are mixed. This layer is flowing at an intermediate speed. Furthermore, the outermost layer is a completely liquefied layer, which flows at a relatively slow flow rate.
[0044]
While the fluid around the water flow power generation unit 18 has the above-described layer characteristics, the water flow power generation unit 18 employed in this embodiment has the three types of blades 41, 45, and 47 as described above. The angle of attack of these vanes is greater the further they are located. That is, the higher the speed is, the faster the rotation is obtained. Therefore, in the ship 1 of the present embodiment, the difference in the flow velocity of the fluid flowing through each layer is offset by the difference in the angle of attack between the blades 41, 45, and 47 of the rotating body 32, and the rotating body 32 receives torque from any layer.
[0045]
Then, by the rotation of the rotating body 32, the magnetic field of the magnet 50 crosses the operation line 52 of the winding 33, and a current is generated in the operation line 52. The winding 33 employed in this embodiment is a single zigzag arrangement of wires, and the N pole and the S pole alternately appear due to the rotation of the magnet 50. The strength and direction change rapidly. However, since the arrangement pitch of each action line 52 is the same as the pitch of the N pole and S pole of the magnet 50, the change in the intensity and direction of the current flowing through each action line 52 is completely synchronized. Therefore, an alternating current is obtained from the winding 33.
In the winding 33 employed in this embodiment, the crossover wires 51 and 53 between the respective action lines are shorter than the normal turtle shell coil. Therefore, the water flow power generation unit 18 employed in this embodiment has high power generation efficiency.
[0046]
In the ship 1 of the present embodiment, the motor 55 is rotated by the electric power generated by the MHD power generation unit 16, the steam power generation unit 17, and the water flow power generation unit 18 described above, and the ship 1 is navigated by the propulsive force of the screw 56.
[0047]
The seawater that has exited the water flow power generation unit 18 is injected toward the sea from the opening at the stern. Substantial propulsion can also be expected from this seawater injection.
In order to stop the marine vessel 1, it is also possible to reverse the screw 56 in the same manner as a normal marine vessel, or to close the gate 58 of the auxiliary waterway 5 and shut off the water flow of the auxiliary waterway 5.
The above is a description of the operation of the ship 1 at the time of navigation. The operation of the ship 1 while the ship 1 is anchored is as follows.
When the ship 1 is anchored, the openings of the main waterways 2 and 3 and the sub waterway 5 are closed, and the two waterways are connected to each other via the waterways 10 and 11 in a ring shape.
[0048]
In this state, as in the case of navigation, the arc generating electrodes 20 are energized to generate arc discharge between the arc generating electrodes 20. Then, similarly to the above, ionized gas is generated, MHD power generation is performed, and power is also generated by the steam power generation unit 17 and the water flow power generation unit 18.
However, the seawater that has exited the water flow power generation section 18 is not discharged to the outside, enters the sub-waterway 5 through the crossover waterway 11, and flows from the stern of the sub-waterway 5 toward the bow. Then, the seawater returns to the MHD power generation unit 16 again, and is heated to perform MHD power generation. Therefore, the energy held by the seawater that has exited the water flow power generation unit 18 is recovered without waste.
[0049]
In the above embodiment, the configuration in which the MHD power generation unit 16 includes the fuel gas supply pipe 21 is adopted, and the gas is supplied from the fuel gas supply pipe 21 and burned in the main water channels 2 and 3. This configuration is a recommended configuration because a large amount of heat can be efficiently obtained, but the present invention can be realized also by omitting the fuel gas supply pipe 21 and merely performing arc discharge of the arc generating electrode. When the power generating device of the present invention is constituted only by the arc discharge of the arc generating electrode, there is a possibility that a part of the seawater flowing through the main waterways 2 and 3 may be burned by violent heating and impact of the arc discharge to generate energy. There is.
[0050]
Further, in the above embodiment, six arc generating electrodes were employed, and a three-phase alternating current was applied thereto. In addition, the number between the arc generating electrodes can be increased or decreased by a multiple of 3, for example, when three-phase alternating current is used. The power source is not limited to the three-phase power used in the present embodiment, but may be a six-phase or more AC.
[0051]
Of course, it is also possible to use DC as a power source. For example, depending on the type and function of a ship, it may be more convenient to generate DC rather than AC. Specifically, in a special ship such as a submarine, it is desirable to use a direct current because a large amount of electric power needs to be charged. In addition, since it is easier for the MHD power generation unit to generate a direct current than an alternating current, it can be said that the ship of the present invention is suitable for a ship that employs the direct current.
In the case of employing DC for the power supply of the ship, the above-described motor will employ a DC motor, but since the DC motor is easy to control the rotation speed, the speed control of the ship becomes easier. .
[0052]
In the present embodiment, the thrust of the ship is mainly the screw thrust by the rotation of the motor 55, and the thrust of the water jet injected from the water current generator 18 is used as an auxiliary. On the other hand, a configuration in which the thrust of the water flow injected from the water flow power generation unit 18 is mainly used and the thrust of the screw is the secondary force, or a configuration in which the boat is propelled only by the thrust of the water flow is also possible.
However, it is generally difficult to control the amount of ionized gas or water vapor generated by the arc discharge, and it is also difficult to retreat the ship by the propulsive force of the water flow. Therefore, it should be avoided to determine the navigation speed and direction only by the thrust of the water flow. Therefore, as described in the present embodiment, it is most preferable that the navigation is performed mainly by screw propulsion.
In the present embodiment, a configuration having two main waterways is disclosed. However, the number of the main waterways is of course arbitrary, and is appropriately selected according to the size of the ship.
[0053]
【The invention's effect】
The ship of the present invention generates power by applying MHD power generation, and navigates using the power.
That is, the present invention generates power using water and a magnetic field, and uses this power for propulsion. Therefore, high efficiency can be expected, and it can be expected that the speed of the ship is further increased.
In addition, the present invention is free from concerns about air pollution and water pollution as in ships using conventional fossil fuels, and has an effect of improving the environment.
[0054]
The ship according to the second aspect of the present invention ejects part or all of the explosive energy generated by the arc discharge from a part of the hull and uses it as a propulsion force. It has the effect of being fast.
[0055]
In the marine vessel according to the third aspect, the fluid flow generated by the arc discharge circulates in the marine vessel to recover energy. Therefore, the ship of the present invention has an effect of high efficiency.
[0056]
The ship according to claim 4 is provided with a waterway switching device, and the main waterway can be switched between an external opening and an annular structure. It is a design.
[0057]
In the marine vessel according to the fifth aspect, since water is smoothly turned into plasma and stable power generation is performed, there is an effect that the propulsive force is stabilized.
[0058]

[0059]
In the rotating body employed in the eighth aspect, energy can be received from the fluid at any part in the radial direction, and there is an effect that the efficiency is high.
