Description

Technical Field

[0001] The present invention relates to the field of energy and power, and specifically to a Dyson cloud particle device used for energy generation, transmission and utilization of solar light. Background Art

[0002] The Dyson sphere is a hypothetical giant man-made structure proposed by British physicist Freeman John Dyson in 1960. Its purpose is to collect all the energy of stars to provide energy for the development of civilization. However, the construction of a theoretical Dyson sphere is a huge project, requiring a huge amount of material and extremely high engineering technology. Even if all the planets in the solar system are dismantled, it may not be enough to build a complete Dyson sphere. The construction process is long and the cost is extremely high. The current human economy and resource conditions are difficult to support. However, with the development of human civilization, the demand for energy continues to grow, while the energy resources on the earth are limited, and the huge energy released by stars is almost inexhaustible. If humans can master the technology to build a Dyson sphere, they can obtain a large amount of clean energy to meet future energy needs. Summary of the invention

[0003] The development of science and technology is constantly moving forward. Although the construction of a Dyson sphere currently faces many technical challenges, such as material strength, space transportation, and structural stability, breakthroughs have been made in fields such as materials science and space engineering, making the construction of a Dyson sphere possible.

[0004] The Dyson cloud particles of the present invention are components of the Dyson sphere, which is a simple, low-cost, foldable and deployable large-scale solar energy generation, transmission and utilization equipment. It cleverly solves a series of problems such as the inconvenience of launching large equipment into space, the low efficiency of solar energy transmission in space, the low temperature in space causing organic polymers to become hard and brittle and unable to be shaped, and the inability of ground photovoltaic power generation at night.

[0005] In another invention (new form of artificial sun (land-based civilian type)), the structure of the solar energy transmission equipment is a large hard fixed circular basin with a soft reflective composite film installed. The principle is to use the lowering of the air pressure in the basin to turn the plane mirror into a concave mirror. However, this structure and principle are not applicable in space because large equipment cannot be launched into space, and there is no atmospheric pressure in space, so it is impossible to form negative air pressure in the basin to turn the plane mirror into a concave mirror. Therefore, it is necessary to redesign the solar energy transmission equipment suitable for the space environment.

[0006] For the convenience of space launch, the present invention adopts a foldable and deployable design in which the main body is made of a soft film for easy folding, and a high-pressure gas storage tank inflates it to automatically deploy. To prevent being hit by space debris, aramid film is used as the main material of the Dyson sphere particles. To prevent the main material from becoming hard and brittle due to the low temperature in space, the part that needs to be deformed uses a main material of an appropriate depth of gray to absorb the heat of sunlight for appropriate heating. After being launched into the predetermined orbit, the high-pressure gas storage tank inflates the annular airbag (gray). When inflating, the annular airbag drives the three-layer soft film to automatically unfold and flatten. The three flat circular soft films form two separated air chambers. The first layer of film is colorless and transparent to facilitate the passage of sunlight; the second layer of film is a mirror reflection composite film for reflecting the incident sunlight; the third layer of film is a sunlight heating back film (gray).

[0007] The first air chamber is between the first and second layers of film, the second air chamber is between the second and third layers of film, and the annular airbag is the third air chamber. By adjusting the air pressures of the first and second air chambers respectively, the diopter of the middle reflection composite film can be controlled to make it a plane mirror, a concave mirror and a convex mirror, respectively achieving the purposes of focusing and scattering. That is: when there is no air pressure in the first and second air chambers, it is a plane mirror and can be used for high-brightness lighting in a specified area; when the first air chamber is pressurized and the second air chamber is not pressurized, it is a concave mirror and can be used for rapid heating at a specified location; when the first air chamber is not pressurized and the second air chamber is pressurized, it is a convex mirror and can be used for large-area lighting in a specified area. The sunlight power increases during focusing and decreases during scattering.

[0008] The peak power of each device during focusing is determined by the aperture of the reflection film of the device. The larger the aperture, the greater the peak power. Of course, it is also related to the incident angle and reflection angle of sunlight.

[0009]

[0010] Through research, it is found that each parabola has a circle that partially coincides with it. Especially when the focal length of the parabola is very long, the coincident part is more, and the radius of the circle that coincides with it is 2 times the focal length. For example, for the parabola y² = 40000x, its focus is at (10000, 0), and it coincides with the circle (x - 20000)² + y² = 400000000, and the radius of the circle is 20000. (As Figure 2 、 Figure 3 shown) In a certain range near the vertex of the parabola, when substituting 0 < x < 1 into these two functions, the obtained y values are similar. The derivative method can also prove that in a specific area, the tangent slopes of the parabola and the circle are also similar, that is, when the x value is relatively small, they coincide. This is the theoretical basis for the fact that part of the area of the spherical concave mirror can focus like the parabolic concave mirror. It's just that when the x value is relatively large, the aberration and distortion of the image formed at the focus will be more serious, but it does not affect the light convergence and energy concentration of the concave mirror.

[0011] Application scenario description: From the first row of the table, it can be seen that at night, in space at an altitude of 20,000 km, a Dyson cloud particle with a diameter of 300m can transfer 100 million watts of optical power to a certain area on the ground. If scattered in the photovoltaic power generation area, photovoltaic power generation will generate at least 10 million watts of electrical power and 10 million degrees per hour, solving the problem of ground transmission of space solar energy. If this 100 million watts of optical power is concentrated on a point on the ground, any target object will be burned instantly. Therefore, in actual applications, equipment should be strictly controlled to prevent accidents.
