Chapter 181, 200 billion to build a Three Gorges in space
In the outer space of the earth, a huge "Hercules" aerospace plane soared into the sky and directly entered the earth's orbit. Inside the aerospace plane, Xie Feng and Duan Yanpeng, wearing the spacesuit logo of Fuyun Group, drove carefully. The aerospace plane slowly moored towards the space port of "Sky City".

This time their mission is to transport a large number of solar panels into space, preparing to build a fat solar farm in space.

This plan was also proposed by Li Fu at the meeting. Huaxia is now also vigorously encouraging private capital to participate in the construction of the space industry. Now there are thousands of space farmlands under construction and operation in space, of which only a small part It belongs to the state, and most of the space farmland is private.

The space solar energy program is also a program recently proposed by the country and strongly encouraged and supported for development. The purpose is very clear, that is, to reduce dependence on traditional energy sources, and more importantly, reduce dependence on external energy sources.

As the most representative enterprise in China's space field, Fuyun Group naturally wants to set an example for others. Whether it is space agriculture or other space industries, Fuyun Group is a pioneer.

Solar power generation is actually very common in space. As small as a satellite has a pair of wing-like solar panels, as large as a space station, space city, space farmland, spacecraft, etc. are composed of many solar panels. The purpose of these solar wings is to absorb solar energy and convert it into electrical energy to provide power for spacecraft, increase life and endurance.

In many cases, a pair of small solar wings is enough to provide sufficient power for the spacecraft, because in space, the sun's light is very strong, without the weakening of the atmosphere, and it can be illuminated all day long. Adjusting the angle is basically possible. Realize vertical 90-degree irradiation, continuously provide electric energy.

In addition, in space, the spacecraft relies on inertial flight most of the time, and generally does not consume energy at this time, so a pair of small solar wings is enough to provide energy for the spacecraft and run for a long time.

Like the "Voyager 1977" unmanned space probe outside the solar system launched by Uncle Sam on September 9, 5, it is still able to work well until now. After decades of flight, it has reached the edge of the solar system.

The reason why it can work continuously for decades is that the energy it carries is actually not enough to support it. The most important source of energy is to use solar wings to obtain energy, and relying on inertial flight itself does not consume Energy, turning off equipment periodically to save energy and so on, so almost half a century later, it is still able to communicate with this side of the earth.

So basically the spacecraft, the one-off ones, will have a pair of solar wings to obtain energy, especially large-scale space stations, space cities, space farms, etc., many of their shells are solar panels, which can Continuous access to solar energy.

However, it seems that there has never been a super-large solar farm dedicated to harvesting solar energy and converting it into electricity in space, so Fuyun Group has set another historical precedent.

The huge aerospace plane slowly parked in the "City of the Sky" space port, its huge belly slowly opened, and the mechanical arm continuously took out the goods inside, and soon the stomach of the aerospace plane was completely emptied.

Then the mechanical arm began to load the aerospace plane with goods, and one meter square standard boxes were continuously transferred in. The goods in these boxes were all the crops produced by Fuyun Group's space farmland, and the quantity was very large. Now it can not only meet the needs of the staff in "Sky City", but also sell it to the country, and even transport it directly to the moon base.

In Sky City, Luo Xiaoyao, Zhan Fei and other dozens of astronauts are extremely busy at this time. They are manipulating the mechanical arms to cultivate and assemble the skeleton of the solar farm.

A solar farm is basically similar to a space farmland. It uses a large sky capsule to form a skeleton, and then subdivides it continuously, installs solar panels, and finally forms a huge solar farm. It can use solar energy to generate electricity or reflect solar energy. To smelt asteroids and more.

With the help of the virtual machine, dozens of astronauts cooperated with each other very tacitly. They concentrated on manipulating the mechanical arms. Outside the city of sky, each mechanical arm was like a flexible hand. They cooperated with each other tacitly, and each one was realized. The planned space capsules are continuously spliced ​​together in space.

Soon, a huge frame appeared in the space, and then this frame was composed of space capsules, and each space capsule had a motor in it. When these engines were activated, the huge frame floated away from the sky gently. City, slowly driving into its own orbit.

After the framework was completed, the astronauts replaced astronauts, entered the aerospace plane, left the city of the sky to catch up, and then began to expand and refine continuously.

Compared with building space farmland, building a solar farm is much simpler, because it only needs to be subdivided, divided into one-meter-long squares, and then installed with solar panels.

Soon, a huge solar power field with a length and width of 100 meters was assembled. With the help of many robotic arms, the work of astronauts is also much easier.

"Start adjusting the angle!"

Inside the skeleton of the space capsule, Luo Xiaoyao controls the computer to start calculating the angle between the solar panel and the sun’s light beam at this time, and then the engine on the space capsule will slowly adjust the angle between the solar panel and the sun’s light. Get maximum energy.

The engine on the space capsule rotated slowly, and each solar panel began to move slowly, and soon the sunlight irradiated vertically on each solar panel.

"Start converting to electricity."

Gently start, the data on the computer began to soar, the situation of each of the 1 solar panels can be accurately grasped, and after an hour, the detailed data on the power generation of the solar panels in space came out.

"The total power generation reaches 12948 degrees. Calculated, the power generation of each electric panel reaches almost 1.3 degrees per hour. This power generation efficiency is a bit amazing."

Luo Xiaoyao looked at the data in the computer and nodded in satisfaction.

Generally speaking, if the solar power generation panels used for civilian use on the earth are not bad, a solar power generation panel of one square meter can generate about 0.5 degrees of electricity a day, but in the sun, the power generation efficiency reaches dozens of times that of the ground. .

Moreover, in space, solar panels can always be perpendicular to the sunlight, and can generate electricity 24 hours a day without being affected by climate and seasonal changes. This power generation efficiency is even higher.

The 10000-square-meter solar farm generates nearly 1.3 kWh in one hour, 24 kWh in 31.2 hours, and 11388 million kWh in a year. You must know that the total power generation of the Three Gorges Hydropower Station is about 1000 billion kWh a year. Almost 1000 million square meters of solar panels can be used as a Three Gorges Hydropower Station.

We must know that the total investment of the Three Gorges Hydropower Station is more than 1000 billion Chinese dollars, which can be counted on the books. If the cost of immigration and other expenses are included, the investment amount will be even greater.

However, at this time, it is necessary to build a 1000 million square solar power plant in space, and its cost is less than 200 billion, which is less than one-seventh of the Three Gorges. This was unimaginable before. The popularity of space shuttles has made the cost of going to and from space lower and lower, and the most expensive ones are these high-tech solar panels.

As time goes by, in space, a huge mirror gets bigger and bigger, and soon the area exceeds 1000 million square meters, which can already be seen with the naked eye on the earth.

"200 billion can build a Three Gorges Hydropower Station in space!"

"The power generated by 1000 million square solar panels in space is equivalent to the Three Gorges!"

"The new energy era has arrived. The country plans to completely phase out traditional fuel vehicles and vigorously promote new energy electric vehicles."

Huaxia's official publicity channels, from TV news, newspapers, the Internet, etc., have once again detonated the entire Huaxia with headlines like this. power plant data.

When seeing the detailed data, whether it is Huaxia's state-owned enterprises, state-owned enterprises, or Huaxia's private capital and power, everyone's eyes turned red at once.

With an investment of less than 200 billion yuan, a Three Gorges hydropower station can be built in space. Anyone can know how huge the profits are. The current electricity price, even for civilian use, is about 0.5 yuan per kilowatt-hour, generating 1000 yuan a year. 500 million degrees, that is, an output value of nearly [-] billion.

Even if the output value shrinks further, if it is calculated as 0.25 yuan per kilowatt-hour, there will still be an output value of 250 billion a year. With an investment of 200 billion, the cost can be recovered in one year, and there may even be profits. There is no better business than this in the world. up.

We must know that when the capital is very small, the rate of return on investment is relatively high, but once the capital reaches hundreds of millions, it is already difficult to obtain such a high rate of return, not to mention the investment of tens of billions, the profit of which is almost Enough to drive people crazy.

The entire Huaxia capital force has not recovered from the huge benefits of space agriculture, and the solar energy project here makes them want to invest their last penny in it.

　I don't know if the calculation of this power generation is correct or not. Is there any data for analysis?
