Abstract

To solve the problem that a transformer for ultra high voltage is required, a device becomes large and cost becomes high although voltage is to be reduced in the transformer since voltage is high, current is small and a charging system is not suitable for general use although output can remarkably be increased if the charging system is adopted as an injection system of a charge to a charge carrier in an electrostatic generator using asymmetric electrostatic force as driving force for the charge carrier.SOLUTION: When a size of each component is reduced to 1/100, voltage becomes low and current becomes high. The voltage can be used in general by converting it into 100 V by a regular coil transformer, and is made into AC by an inverter.EFFECT: The voltage is lowered, the current is increased and a generator for general use can be obtained only by reducing component sizes without using a transformer for ultra high voltage in which the device becomes large and cost becomes high.SELECTED DRAWING: Figure 14

Description

In the present invention, the electric charge is injected into the charge carrier by a charging method, and the output in the electrostatic generator using the asymmetric mirror image force as the driving force of the charge carrier is reduced in voltage without using a coil transformer to generate a current. With regard to increasing mirror image force driven electrostatic generators.

Usually, in an electrostatic generator using an asymmetric electrostatic force as a driving force, there are an inductive method and a charging method as a method of injecting a charge into a charge carrier. Among them, it is reported that the charging method has a large amount of charging charge.

However, although it is possible to increase the output by the charging method, the content is high voltage and small current. For example, a charging potential source (hereinafter referred to as a charging electret according to an embodiment, and the term electret is not only an electret that artificially injects and holds an electric charge from the outside, but also a strong dielectric that naturally holds an electric charge. When the potential of (including) is 180,000V, the voltage is 140,000V and the current is 18mA according to the simulation results. It is possible to make it AC and use a coil transformer to lower the voltage and increase the current, but in order to make it a 100V AC power supply, the ratio of the number of turns of the primary and secondary coils must be 1: 1000. It must be a large-scale transformer and a power source that is not suitable for home use.

The purpose of lowering the output voltage and increasing the current to make it a generator for general use was achieved by reducing the size of the main parts to 1/100.

There are several electrostatic power generation methods that use asymmetric electrostatic force as the driving force of the charge carrier, but among them, the simplest mirror image power driven electrostatic generator explains how to increase the output voltage and current. do.

Normally, the electrostatic force acting on the electric charge q placed in the electric field E is calculated by Eq. (1) and is called Coulomb force.
F = qE
(1)

In FIG. 1, reference numeral 1 is a high-voltage electrode, reference numeral 2 is a grounded first counter electrode, reference numeral 3 is a point charge, reference numeral 4 is a vector of electrostatic force acting on the point charge, and reference numeral 5 is an electric field (reference number 5). (Electrical line of force) and reference numeral 6 indicate a grounded second counter electrode. That is, on the left side of the center of FIG. 1, for example, when the electric field strength is 10 ⁶ V / m and the charge amount of the point charge is 10 ^-7 C, the electrostatic force acting on the point charge is 0.100 N. On the other hand, as shown on the right side of the center of FIG. 1, when the direction of the electric field is reversed, the direction of the electrostatic force acting on the point charge is also reversed, but its magnitude (absolute value) is 0.100N and does not change.
However, Coulomb's law applies only to point charges or spherical charged bodies that can be regarded as point charges.

On the other hand, when the applicant obtains the electrostatic force acting on a non-spherical charged conductor placed in an electric field, the calculation cannot be performed by Coulomb's law, and therefore the two-dimensional difference method described in Patent Document 1 is described. Was used to simulate the electrostatic force acting on the conductor before and after the direction of the electric field was reversed. Specifically, as shown in FIG. 2, the shape of the charged conductor shown by reference number 7 is a gutter shape, and the amount of charge and the strength of the electric field are the same as those in FIG.
As a result, it was found that when the direction of the electric field was reversed, the strength of the electrostatic force decreased from 0.083N to 0.038N, which was less than half. Hereinafter, this is referred to as an asymmetric Coulomb force.

As shown in FIG. 3, when the point charge 3 is at a distance r from the ground conductive flat plate 2, the electrostatic force calculated by the equation (2) acts on the point charge. Hereinafter, this is referred to as mirror image power.
F = q ² / 4πε ₀ (2r) ²
(2)
This equation also applies to point charges. Therefore, as shown in FIG. 4, when the shape of the conductive charged body is a gutter type, the electrostatic force acting on the gutter-shaped conductive charged body 7 is obtained by simulation. As a result, when the charge amount q was 10 ^-6 C and the interval r was 1.0 mm, it was 32.4 N when the gutter-shaped 7 opening was opposed to the flat plate 2, but when the bottom surface was opposed, it was more than doubled. It became 69.0N. Hereinafter, this is referred to as asymmetric mirror image force.

Therefore, in the mirror image force drive type electrostatic generator, the effects of both the asymmetric Coulomb force and the asymmetric mirror image force are used. Figure 5 shows the basic structure of the mirror image force driven electrostatic generator.
The main components are only three points: the charging potential source 8 (usually an electret is used (hereinafter referred to as the charging electret)), the horizontal gutter type charge carrier 7, and the recovery electrode 9. Actually, as shown in FIG. 6, a recovery electrode capacitor 10, a charge injection conductive terminal 11 and a charge recovery conductive terminal 12 are added, but for the sake of simplification of the explanation below, mainly only three main parts are used. conduct.

When the charge carrier 7 enters the charging electret 8 from the left and reaches the position shown in FIG. 6, an air condenser is formed between the upper and lower flat plates 72 of the charge carrier 7 and the charging electret 8. At this time, when the charge carrier 7 is grounded by the charge injection terminal 11, the charge charge to the air condenser is injected into the charge carrier 7 from the ground. After that, the charged charge carrier 7 goes further to the right and enters the recovery electrode 9. Therefore, the electric charge is electrically connected to the recovery electrode 9 by the charge recovery terminal 12, the charged charge is accumulated in the recovery electrode capacitor 10 through the recovery electrode 9, and further flows to an external load through a circuit (not shown).

When the charging electret 8 is negatively charged, the charge carrier 7 is positively charged. As a result, a Coulomb force acts to the left by the negatively charged electret on the charge carrier 7 traveling to the right between the charging electret 8 and the recovery electrode 9. In addition, the back electrode of the electret also exerts a mirror image force to the left.
On the other hand, the recovery electrode exerts a mirror image force pointing to the right. Immediately after leaving the charging electret 8, the resultant force of the leftward Coulomb force and the mirror image force is strong, but when approaching the recovery electrode, the rightward mirror image force becomes stronger.

Due to the asymmetric effect, the leftward Coulomb force and mirror image force acting on the edge of the rear upper and lower horizontal plate 72 of the horizontal gutter type charge carrier 7 are weak, and the electrostatic force acting vertically on the front and back of the horizontal plate 72 is upward and downward. The directions are offset by the same strength, and the rightward mirror image force acting on the front vertical plate portion 71 is strong. As a result, the rightward electrostatic force becomes stronger than the leftward electrostatic force, and the charge carrier 7 can reach the recovery electrode 9 from the charging electret 8. Therefore, if the charge transferred by the charge carrier 7 is recovered by the recovery electrode 9, this device becomes an electrostatic generator. If not recovered, it becomes an electrostatic motor.

Therefore, let's find the electrical output, that is, the electric power, as an electrostatic generator by simulation.
The device configuration of the mirror image force drive type electrostatic generator is shown in FIGS. 7 and 8. FIG. 7 is a perspective view of a charge carrier disk on which a charge carrier is mounted, and FIG. 8 is a perspective view of the entire device. In both figures, reference numeral 8 is a charging electret, 7 is a charge carrier, 9 is a recovery electrode, 14 is a rotatable charge carrier disk on which the charge carrier 7 is mounted, and 13 and 15 are the same facing each other. The charge recovery disk 8 and the recovery electrode 9 are installed and fixed at the positions, and the charge recovery disk 16 is a rotation axis. This set of devices will be referred to as one unit below.

Six gutter-shaped charge carriers 7 having a length of 60 mm are arranged at intervals of 60 degrees on a charge carrier disk 14 having a radius of 100 mm at 35 mm to 95 mm from the center. The width and height of the charge carrier 7 is 10 mm. The center of the charge carrier 7 in the length direction is 65 mm from the center, and therefore its circumference is 408 mm. Place four pairs of charging electret 8 and recovery electrode 9 every 102 mm. The distance between the front recovery electrode 9'and the charging electret 8 is 20 mm, the width of the charging electret 8 is 20 mm, the distance to the recovery electrode 9 is 32 mm, and the width of the recovery electrode 4 is 30 mm. The distance between the rear flat plate 72 of the charge carrier 7 and the charging electret 8 is 1.0 mm, and the distance between the upper and lower charge recovery disks is 20 mm.

The charge density of the charging electret is set to the highest value currently available, -2.0 mC / m ² , the thickness of the electret layer made of Teflon (registered trademark) resin is 1.6 mm, and its relative permittivity is 2.0. At that time, the surface potential of the electret becomes 180,709V.
In reality, the high potential is assumed to be in vacuum because the insulation breakdown of air occurs and cannot be maintained in the atmosphere. Further, a special construction method is required to form the high potential in a vacuum, but this is omitted here.
In this state, when the charge carrier 7 comes to the position shown in FIG. 6 and is grounded by the charging ground terminal 11, 1.47 μC of charge is charged and injected.

Here, patent document 1 shows the details of the electrostatic force received by the charge carrier 7 into which a charge of 1.47 μC is injected until the tip of the charge carrier 7 passes through the charging electret 7 and reaches the recovery electrode 9. It is obtained by simulation by the difference method, and the result is shown in FIG.
From the figure, after the charge carrier 7 exits the charging electret 8, the electrostatic force acting on the charge carrier 7 is negative, that is, leftward for about 7.5 mm, but positive, that is, when it exceeds 7.5 mm. It is clear that it turns to the right and its absolute value becomes larger.

As a result, the charge carrier 7 that has reached the recovery electrode 9 is left with an excess kinetic energy of 0.205J. Assuming that there is no drag in vacuum and no mechanical friction, all of this extra kinetic energy can be used to lift the carrier charge to a higher electrical potential.
The potential V at which the charge q can be lifted by the surplus energy W can be obtained by Eq. (3).
V = W / q
(3)
That is, it becomes 139,632V. This is the highest potential that can be recovered, that is, that can generate electricity (hereinafter referred to as the recovered potential).

Here, when one charge carrier 7 makes one rotation, it passes through the charging electret 8 and the recovery electrode 9 four times, so that the amount of charge transferred and recovered during that time is calculated by the formula 1.47 μC × 4 = 5.88. Represented by μC.
Since there are six charge carriers 7 on the charge carrier disk 14, the amount of charge carried when the charge carrier disk 14 makes one rotation is 5.88 μC × 6 = 35.28 μC.
Assuming that the maximum rotation speed of the ball bearing used is 30,000 rpm, the rotation speed of the charge carrier disk 14 is 500 rotations per second. Therefore, the amount of charge transferred per second is 35.28 μC × 500 = 17640 μC, that is, 17.64 mA.
As a result, the amount of power generation P is the product of the current i and the voltage V, which is calculated by Eq. (4) and becomes 2458W.
P = I * V
(Four)
Therefore, for example, a device such as a 20 cm × 20 cm, 2 cm thick CD cassette can generate more than 2 kW.
However, for a general-purpose power supply, the voltage of 140,000V is too high and the current of 17.6mA is too low. It is possible to use an alternating current and use a coil transformer to lower the voltage and increase the current, but this is not practical because the ratio of the primary and secondary windings of the coil transformer is as high as 1000: 1. ..

Therefore, as the first embodiment, in order to reduce the recovery potential from 140,000V to 1,400V, the device size of the conventional example is reduced to 1/100 in all three directions of XYZ.
That is, the width and height of the charge carrier 7 are reduced from 10 mm to 0.1 mm, and the length is reduced from 60 mm to 0.6 mm. In addition, the width and length of the charging electlet 8 are changed from 20 mm and 60 mm to 0.2 mm and 0.6 mm, respectively, and the width and length of the recovery electrode 9 are changed from 30 mm and 60 mm to 0.3 mm and 0.6 mm, respectively. The distance between the recovery electrodes 9 is also reduced from 32 mm to 0.32 mm.

Then, the reduced charge electret 8 and the recovery electrode 9 are formed radially on the front surface of the charge recovery disk 15 having a radius of 100 mm and the back surface of the charge recovery disk 13 having the same diameter, respectively, as shown in FIG.
Since the length of the reduced charging electret 8 is 0.6 mm, 100 pieces are arranged at intervals of 0.8 mm in the radial direction from the point 16.8 mm to the point 96.0 mm from the center as shown in the figure. In the figure, only 5 are displayed for simplification.
Then, the recovery electrode 9 is placed in the lateral direction of the charging electret 8 at a distance of 0.32 mm. That is, the charging electret 8 and the recovery electrode 9 are alternately arranged in the circumferential direction. In the figure, only a part of it is shown for simplification.

Here, the 100 annulus in which the charging electret 8 and the recovery electrode 9 are alternately arranged is referred to as the first circumference, the second circumference, or the 100th circumference from the outside toward the center point. In this case, the radius of the first circumference is 96 mm, so its circumference is 603 mm. If the distance between the front recovery electrode 9'and the charging electret 8 is 0.24 mm, the width of the charging electret 8 is 0.20 mm, the distance to the recovery electrode 9 is 0.32 mm, and the width of the recovery electrode 4 is 0.30 mm. The set will be 1.06mm, and 570 sets will line up on the first lap.
Also, since the circumference of the second circumference is 598 mm, 564 pairs are lined up. And on the 100th lap, since the circumference is 106 mm, 100 pairs are lined up.

Further, as shown in FIG. 11, the reduced charge carrier 7 is also arranged radially from the first circumference to the 100th circumference. Since the distance between adjacent charge carriers 7 is 0.55 mm, 1097, 1088, and 192 charge carriers 7 are placed on the first, second, and 100th laps, respectively.

The thickness of the Teflon® layer 81 of the charging electret 8 is also reduced from 1.6 mm to 0.016 mm, and the distance between the charging electret 8 and the rear flat plate 72 of the charge carrier 7 is also reduced from 1.0 mm to 0.01 mm. .. The relative permittivity of the Teflon layer, 2.0, and its charge density, -2.0 mC / m ² , remain unchanged. As a result, the surface potential of the charging electret 8 drops from -180,000V to -1,800V. However, the charge density of the charged and charged charge carrier does not change. This is because the ratio between the dielectric thickness of the Teflon (registered trademark) layer (the value obtained by dividing the thickness by the relative permittivity) and the distance between the charging electret 8 and the rear flat plate 72 of the charge carrier 7 does not change. be. However, since the area of the charge carrier 7 is reduced to 1 / 10,000, the amount of charge is also reduced to 1.47E-10 [C], which is 1 / 10,000 of 1.47 μC.

Under the above conditions, the reduced charge carrier 7 charged in 1.47E-10 [C] receives the electrostatic force while moving from the reduced charging electret 8 to the reduced recovery electrode 9 in the same manner as in the conventional example. I simulated it. The results are shown in FIG.
As shown in the figure, immediately after exiting the charging electret 7, a negative, that is, a leftward force is received, but when the rear end of the charge carrier 7 is 75 μm away from the charging electret 8, a positive, that is, a rightward force is applied. It turns out that it is much stronger than the leftward force. As a result, the charge carrier 7 that has reached the recovery electrode 9 holds 0.205 μJ of kinetic energy. Therefore, with the surplus energy, the electrical potential of the charge of 1.47E-10 [C] can be increased to 1396V. That is, the recovery potential is 1396V.

Therefore, on the first lap, there are 597 sets of charging electrets 8 and recovery electrodes 9, and 1097 charge carriers 7, and each charge carrier 7 has a charge of 1.47E-10 [C]. Since it is charged, the amount of charge recovered by the 597 recovery electrodes 9 in one rotation of the charge carrier disk 14 is 597 * 1097 * 1.47E-10 [C] = 9.17E-5 [C. ]become.
Assuming that the charge carrier disk 14 rotates at the maximum rotation speed of the bearing of 30,000 rpm, it rotates 500 times per second. Therefore, the charge of 9.17E-5 [C] * 500 = 0.0459 [C] is recovered in 1 second. That is, the recovery (power generation) current is 0.0459A. Since the recovery potential is 1396V, the amount of power generation is 0.0459A * 1396V = 64.0W. When calculated in the same manner, the current on the 100th lap is 0.0014A and the amount of power generation is 2.0W.

When all the laps 1 to 100 are added together, the current is 1.85A, the voltage is 1396V, and the output is 2581W. In other words, in the device before reduction, the current was 0.0176A, the voltage was 139,600V, and the output was 2458W, so the voltage was reduced to 1/100, the current was 105 times, and the output was 105 times. With this voltage, the ratio of the number of primary and secondary windings of the coil transformer is 10: 1, and it is easy to convert to 140V, 18.5A.

Incidentally, the charge density of the charge carrier 7 is the same, (3600 mm ² in the conventional example, 3866Mm ² in this embodiment) about the same charge carrier area on the charge carrier disc 14 Nevertheless, current is 105 times This is because the distance between the charging electret 8 and the recovery electrode 9 has been reduced from 32 mm to 0.32 mm, which is 1/100, and the time from charging to recovery has been reduced to 1/100. That is, in this embodiment, the charging / recovery was performed 100 times while the charging / recovery was performed once in the conventional example.

From this result, it is clear that the size in the traveling direction of the charge carrier 7 is related, and the size in the right angle (up and down) direction is not related. Therefore, the length of the charge carrier 7 can be set to 0.6 mm or more. However, when it is returned to 60 mm as in the conventional example, the distance between the charge carriers 7 is narrow near the center of the charge carrier disk 14 and wide at the circumferential portion, which is inconvenient. Therefore, for example, it seems appropriate to set the length to 6.0 mm and arrange it in 10 laps from the circumference to the center.

In the above, when the above length is 6.0 mm, the amount of power generation is about 600 w even with only the first lap, and as described below, multi-layering is possible, so only the first lap that simplifies the manufacturing method is selected. It is a branch.

Further, in this case, if the charge carriers 7 are electrically connected to each other and the spacing between the charge carriers is the same as the spacing between the charging electrets 8 and the recovery electrodes 9, the charge injection conductivity of the individual charging electrets 8 is set. The terminal 11 and the charge recovery conductive terminal 12 of each recovery electrode 9 are not required. That is, instead, a high-speed switching transistor connecting the charge carrier 7 and the ground and a high-speed switching transistor connecting the charge carrier 7 and the recovery electrode 9 are placed, and when the charge carrier 7 enters the charging electret and the recovery electrode When you enter, you can turn it on momentarily.

Furthermore, since the three directions of XYZ have been reduced to 1/100, the height of the device has also been reduced from 20 mm to 0.2 mm. Therefore, if the CD cassette size of 200 * 200 * 20 mm of the conventional device is used, 100 units can be stacked, and the output is calculated to be 258 kW (1400 V, 185 A).

In addition, the electrostatic force acting per unit mass of the charge carrier 7 has increased significantly. That is, the mass of the charge carrier 7 of the conventional example was 0.972 g. On the other hand, the mass of the charge carrier 7 of this example was 0.972E-6g of 1 / 100.000.
On the other hand, the electrostatic force acting on this was the maximum value of 51.36N in the conventional example and 0.005136N of 1 / 1.000 in this example. As a result, the magnitude of the electrostatic force acting per unit mass is 100 times that of the conventional example in this embodiment. As a result, the charge carrier 7 can be driven by overcoming the air resistance without creating a vacuum inside the device.

Hereinafter, the second embodiment will be described. In order to realize 140V directly without using a coil transformer, theoretically, the size of the conventional example should be 1/1000 instead of 1/100. However, in this case, the width of the charging electret 8 is 20 μm and the thickness is 1.6 μm. Therefore, it is difficult to manufacture.
Therefore, in Example 2, the charge density of the charge electret 8, from -2.0MC / m ² of Example 1, was reduced to -0.2MC / m ² of 1/10. That is, it is a value normally used in an electrostatic air filter or the like.

As a result, the amount of charge charged and injected into one charge carrier 7 becomes 1.47E-11 [C], which is 1/10, and the surplus energy when reaching the recovery electrode 9 is 1/100. It became 2.05E-9J. As a result, the recovery potential obtained by Eq. (1) was 1/10 of 140V.
Then, as in Example 1, when the current and the amount of power generation from the first lap to the 100th lap were calculated and totaled, they were 0.184A and 25.8W. Therefore, when 100 units are stacked on a CD cassette size, the output is 18.4A and 2.58kW. Therefore, since it is DC 140V, it can be easily converted to AC 100V with a low-priced transistor inverter and can be used as a household power supply.

Hereinafter, the third embodiment will be described. In Examples 1 and 2, the charge carrier 7 was arranged radially on the charge carrier disk 14, and the charge carrier disk 14 was rotated between the charge recovery disks 13 and 15. As schematically shown in FIG. 13, the charge carrier 7 may be arranged parallel to each other on the charge carrier belt 14 and run between the upper and lower fixed electrode plates 13 and 15 with an asymmetric mirror image force.
Specifically, the widths of the charge carrier 7, the charging electret 8, and the recovery electrode 9 used in Examples 1 and 2 remain the same, and only the length is extended from 0.6 mm to 180 mm, which is 300 times larger, and the charge has a width of 190 mm. They were arranged on the carrier belt 14 and the upper and lower fixed electrode plates 13 and 15 at right angles to the traveling direction and parallel to each other.

In such a configuration, the amount of charge charged in the charge carrier 7 was obtained by a two-dimensional difference method simulation (Patent Document 1) in the same manner as in Example 2, and the result was 4.402E-9 [C], which was 300 times larger. rice field. Further, the electrostatic force acting on the charged charge carrier is also increased by 300 times, and the surplus energy is also increased by 300 times. As a result, the recovery voltage became the same as 140V.

Here, since the widths of the upper and lower fixed electrode plates 13 and 15 and the charge carrier belt 14 are 180 mm, it is 360 mm in one round. Here, one set of the charging electret 8 and the recovery electrode 9 is lined up at intervals of 1.06 mm, so there are 340 sets. Further, since the charge carriers 7 are arranged at intervals of 0.55 mm, the number is 655.
Therefore, one rotation of the belt 14 causes 340 * 655 = 222,700 times of charging / recovery, that is, power generation. Since the charge of 4.402E-9 [C] is transferred by one charge / recovery, the charge of 4.402E-9 [C] * 222,700 = 9.8E-4 [C] is transferred by one rotation of the belt 14. , Increased from 0V to 140V.
Assuming that the linear velocity of the belt 14 is 36 m / s, the belt 14 rotates 100 times per second. As a result, the generated current is 9.8E-2 (A). Since the recovery voltage is 140V, the amount of power generation is 13.7W. Assuming that the width of the housing 18 is 200 mm and the height is 1 mm, 20 stages can be stacked in the size of a CD cassette, so the output is 140V, 1.96A, 274W.

Instead of circulating the charge carrier belt 14, the charge carrier plate may be reciprocated. In this case, the force acting in the return process is, for example, a spring force. It may be magnetic force, gravity, or the like.

Hereinafter, the fourth embodiment will be described. In the third embodiment, the long charge carrier 7 is arranged on the circulating belt, but instead of this, it may be arranged on the rotating cylinder 14 as shown in FIG. In the figure, only 6 charge carriers 7 and 3 sets of charging electret 8 and recovery electrode 9 are displayed, but in reality, 1028 and 533 are shown as described below. Have been placed.
In this case, the sizes of the charge carrier 7, the charging electret 8, and the recovery electrode 9 and their intervals, and the charge density of the charging electret 7 are the same as in the third embodiment, so that the amount of charge charged and the electrostatic force acting on the charge are also in the embodiment. It becomes the same as 3, and the surplus energy that reaches the recovery electrode is also the same, and the recovery potential is also 140V.

However, since the peripheral length of the belt 14 and the peripheral length of the cylinder 14 are different and the peripheral speeds of both are different, the amount of power generation is different. That is, assuming that the diameters of the inner / outer fixed electrode cylinders 13 and 15 and the charge carrier cylinder 14 are 180 ± 0.1 mm, the diameter is 565 mm in one circumference. Here, since the sets of the charging electret 8 and the recovery electrode are lined up at intervals of 1.06 mm, there are 533 sets. Further, since the charge carriers 7 are arranged at intervals of 0.55 mm, the number is 1028. Therefore, one rotation of the cylinder 14 causes 533 * 1028 = 548,502 times of charging / recovery, that is, power generation.
Since the charge of 4.402E-9 [C] is transferred by one charge / recovery, the charge of 4.402E-9 [C] * 548,502 = 1.33E-3 [C] is transferred by one rotation of the cylinder 14. , Increased from 0V to 140V.
Assuming that the rotation speed of the cylinder 14 is 30,000 rpm, which is the maximum rotation speed of the ball bearing that holds the cylinder 14, the cylinder 14 rotates 500 times per second. As a result, the generated current becomes 1.2A. Since the recovery voltage is 140V, the amount of power generation is 168W.

Since the size of the housing 18 of this device is 200 * 200 * 200 mm, the charge density of the charging electret is -0.2 mC / m ² , and the amount of power generation per volume is an order of magnitude compared to Examples 2 and 3 which are the same. The difference is small. This is because there is a large wasteful space inside the charge carrier cylinder 14.
By gradually reducing the diameters of the electrode cylinders 13 and 15 and the charge carrier cylinder 14 and inserting a large number of them, the amount of power generation can be significantly increased.

In addition, even if the internal wasteful space is left, the charge density of the charging electret can be set to the maximum value that can be manufactured at present, -2.0mC / m2, and the power generation current is 12A, the recovery voltage is 1400V, and the power generation amount is. It will be 16.8kW.
Since the recovery voltage is the maximum recoverable voltage, any value of 1400V or less can be taken. For example, if it is 140V, it will be a 1.68kW generator at 12A. Therefore, if three power generation devices are stacked, the power generation will be 36A and 5.0kW, which will be a general household power source.

In the above, all four examples have been described with a mirror image force driven electrostatic generator using charge injection by a charging method, but in the case of the same electrostatic motor and electrostatic accelerator, they act on the charge carrier 7 in which the charge is injected. The only problem is the magnitude of the electrostatic force that is applied, no matter how high the potential of the charging electlet is, there is no need to reduce the size.
