Chapter 167: Civilization Level 4! Day by Day Type 1 Solar Panel!

Dyson sphere is a solar energy harvesting technology proposed by physicists named Dyson in 1960.

Simply put, it is to make a huge spherical solar panel that envelops the entire sun, thus completely collecting solar energy. I have to say, this is a crazy and magnificent fantasy!

With the Dyson sphere, humans can completely collect all the energy radiated by the sun, which is also the hallmark technology of level 2 universal civilization.

In 964, astronomer Kardashev proposed a method of classifying civilizations according to their ability to use energy.

The first-class cosmic civilization is also called “planetary civilization”.

This level of civilization has the ability to extract and utilize almost all the energy and energy sources on the planet it is on. The secondary cosmic civilization is also called “stellar civilization”.

The civilization has reached the ability to leave its planet at will, and then develop and use the energy of the stars near its planet, the entire star system is under control, and it can habit, shuttle and develop energy on all the planets of the star system at will.

Level 328 Universal Civilization is also called “Galaxy Civilization”.

The civilization can easily control the galaxy in which it is located, and can also develop and use all the energy in the galaxy at will, and even draw the energy required by its own civilization from the existing black holes in the universe.

The fourth-level universal civilization is the “universal civilization”.

The civilization has been able to develop and utilize 7080% of the energy in the universe, and even develop and use the energy of the entire universe, as for what state to control, human beings are currently unimaginable.

Simply put, level 3 or 4 is still pure fantasy.

Before the Tiangong Power Plant, human civilization was at about level 0.75. For a technological civilization, energy is the top priority.

In the era before Jiang Fan’s opening, the most important energy source was oil. The petrodollar strategy of the mold country is world-famous.

Even a technologically backward oil-producing country can enjoy the worship of all mankind with this black gold in a paralyzed posture. After Jiang Fan built the Tiangong Power Plant, this situation was ended.

Whether it is oil, coal, tidal energy, wind energy, etc., the vast majority of the energy that human beings are using is essentially a secondary energy after solar energy conversion.

The whole earth can be seen as an oversized power bank.

In the Sun’s nine-planet system, most of the solar radiation energy is wasted, and the planets in the solar system currently receive only about 1 billionth of the solar radiation energy.

A highly developed civilization must have the ability to surround the sun with a huge spherical structure, so that most of the sun’s radiation energy is intercepted, and only in this way can it support this civilization for a long time and develop it to a sufficient height.

Originally, the Dyson ball was still very far away from humans, but now Jiang Fan saw a ray of hope. With the current technology in his hands, building a real Dyson ball is really difficult, very difficult!

Wireless power transmission only allows Jiang Yuan to touch the edge of the Dyson ball.

Simply put, it is to place a transit station satellite that orbits the sun synchronously with the earth every 20 million kilometers along the route from the earth to the sun.

Since the Earth’s orbit around the Sun is elliptical and the Sun is located in a focal point, the distance between the Sun and Earth varies from time to time. The maximum distance at aphelion is 152.1 million kilometers; The minimum distance to perihelion is 147.1 million kilometers.

In other words, up to 8 transfer stations can transmit solar energy collected near the sun to Earth! The question is how to arrange solar panels in near-solar orbit.

This creates a huge number of technical problems.

For example, the closer you are to the sun, the higher the light intensity, which is inversely proportional to the square of the distance away from the sun.

Take Mercury as an example, its distance from the Sun is about 1:2.5 compared to Earth, because the Sun on Mercury is about 7 times more intense than Earth!

Take the vacuum solar panels of the Tiangong Power Plant as an example, which can only withstand up to 4 times this value. Recently, the vacuum solar panels are about to be baked by the sun.

Therefore, it is necessary to develop ultra-high temperature solar panels.

For example, the Dyson sphere is an unimaginably huge project, which will consume astronomical amounts of matter. The radius of the sun is more than 100 times that of the Earth, and the surface area reaches more than 10,000 times that of the Earth.

The density of ultra-high temperature solar panels must be light enough that if they are existing solar panels, even if all the material of the entire earth is turned into solar panels, it will not cover the sun.

Moreover, the Dyson ball must not be close to the surface of the sun, which is too hot.

The Dyson sphere must be some distance from the sun, and as the distance increases, the amount of material required will increase according to the square level! In addition, even if it is built, it is difficult to estimate the materials, energy and time consumed to send massive solar panels to near-day orbit.

“So, if you want to build a Dyson ball, Mercury is the best place to get it!”

“Minerals are mined directly on Mercury and a near-solar version is produced and then transported to be installed close to the sun.”

Jiang Fan thought silently.

Previously, the reason for the development of the Mercury power plant with great fanfare was actually a cover-up.

The fundamental purpose is to send enough manpower and materials to conduct a field trip to Mercury and confirm what minerals can be mined on Mercury.

In addition, the eight satellite power transfer stations under construction by Dajiang Group also have legitimate reasons and have not attracted much attention from 280 in other countries.

After all, after Mercury builds the power plant, it has to transport the electricity back. In front of Jiang Fan were 2 special solar panels.

One piece is golden, as thin as a cicada wing, and very soft, like a plastic bag. One piece is traditional black, thick and thick, but can withstand temperatures of 3,000 degrees. These two solar panels were developed by the laboratory under his orders regardless of the cost.

The golden one meets the lightweight requirements of the Dyson ball, and can be produced from minerals on Mercury, but it is not resistant to high temperatures. The black one meets the requirements of high temperature resistance, but it is dead and dead.

The common feature is that both boards are typical laboratory products, and the cost of a small piece is as high as more than 10 million, which has no practical value at all.

The scientists in charge of research and development could not think of a purpose for the two boards.

In their view, these are two typical exploratory studies, pointing the way for future research and development, practical value = 0.

“But, in my hands, it’s a completely different story.”

Jiang Fan smiled slightly: “System, I want to combine and deduce ultra-light softened solar panel technology and high-temperature resistant solar panel technology!” 】。 ”
