Chapter 181, 20 Billion to Build a Three Gorges Dam in Space

In outer space, a huge "Hercules" space plane soared into the sky and entered the Earth's orbit directly. Inside the space plane, Xie Feng and Duan Yanpeng, wearing the logo of Fuyun Group's space suits, carefully drove the space plane to the space port of "Sky City" and slowly parked.

This time their mission is to transport a large number of solar panels into space and prepare to build a fat solar power plant in space.

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

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

As the most representative enterprise in China's space field, Fuyun Group naturally has 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. From small satellites that have a pair of wing-like solar panels to large space stations, space cities, space farms, spacecraft, etc., there are many solar panels that make up the solar wings. The purpose of these solar wings is to absorb solar energy and convert it into electricity, provide power for spacecraft, and increase life and endurance.

In many cases, a pair of small solar wings is enough to provide sufficient electricity for spacecraft, because in space, the sunlight is very strong, there is no atmospheric weakening, and it can be irradiated all day long. If the angle is adjusted, it can basically achieve vertical 90-degree irradiation and provide electricity continuously.

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

Like the "Voyager 1" unmanned space probe in the outer solar system launched by Uncle Sam on September 5, 1977, it can still 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 and still function well is that the energy it originally carried is actually not enough to support it. The most important source of energy is to use solar wings to obtain energy. In addition, it does not consume energy by relying on inertial flight itself, and shuts down the equipment regularly to save energy, etc., so it can still contact the earth for almost half a century.

So basically, except for the disposable ones, all spacecraft will have a pair of solar wings to obtain energy, especially large space stations, space cities, space farms, etc., many of their shells are solar panels, which can continuously obtain solar energy.

However, it seems that there has never been a real super-large solar power plant dedicated to obtaining solar energy in space and converting it into electricity, so Fuyun Group has also opened a historical precedent.

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

Then the robotic arm began to load the space plane with goods. One-meter square standard boxes were constantly transferred in. The goods in these boxes were all crops produced by the space farm of Fuyun Group. The quantity was very large. Now it can not only meet the needs of the staff in the "Sky City", but also be sold to the country, and even directly transported to the moon base.

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

The solar power plant is basically the same as the space farm. It uses a large sky capsule to form a skeleton, and then continuously subdivides and installs solar panels to eventually form a huge solar power plant. It can use solar energy to generate electricity, and it can also reflect solar energy to smelt asteroids, etc.

With the help of the virtual machine, dozens of astronauts cooperated with each other very well and concentrated on manipulating the robotic arms. Outside the Sky City, the robotic arms were like flexible hands, cooperating with each other tacitly, and one by one, the planned space capsules were constantly spliced ​​in space.

Soon, a huge frame appeared in space, followed by this frame composed of space capsules, each of which had an engine. When these engines were started, the huge frame gently floated away from the sky city and slowly drove into its own orbit.

After the frame was completed, the astronauts changed to astronauts, entered the space shuttle, left the sky city and chased it, and then began to expand and refine it continuously.

Compared with building space farms, building solar power plants is much simpler, because it only needs to be subdivided, the area is divided into one-meter-long squares, and then solar panels are installed.

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

"Start adjusting the angle!"

Inside the frame of the space capsule, Luo Xiaoyao controlled the computer to calculate the angle between the solar panel and the sunlight column at this time, and then the engine on the space capsule would slowly adjust the angle between the solar panel and the sunlight, so that vertical irradiation could obtain the maximum energy.

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

"Start converting to electricity."

Gently started, the data on the computer began to soar. The situation of each of the 10,000 solar panels could be accurately grasped. An hour later, the detailed data of solar panel power generation in space came out.

"The total power generation reached 12,948 degrees, and the power generation of each panel per hour reached about 1.3 degrees. This power generation efficiency is a bit amazing."

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

Generally speaking, if the lighting conditions are good, a square meter of solar panels for civilian use on the earth can generate about 0.5 degrees of electricity a day, but in the sun, the power generation efficiency is 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, so the power generation efficiency is even higher.

A 10,000 square meter solar power plant can generate nearly 13,000 kWh per hour, 312,000 kWh in 24 hours, and 113.88 million kWh per year. It should be noted that the total power generation of the Three Gorges Hydropower Station is about 100 billion kWh per year. If calculated in this way, the power generation of about 10 million square meters of solar panels can be used as a Three Gorges Hydropower Station.

It should be noted that the total investment of a Three Gorges Hydropower Station, which can be counted on the books, has reached more than 100 billion yuan. If immigration and other expenses are included, the investment amount will be even greater.

However, at this time, to build a 10 million square meter solar power plant in space, its cost is less than 20 billion, less than one-seventh of the Three Gorges. This was unthinkable in the past. The popularity of aerospace planes has made the cost of traveling to and from space lower and lower. The highest cost is these high-tech solar panels.

As time goes by, a huge mirror in space is getting bigger and bigger, and soon the area exceeds 10 million square meters, which can be seen with the naked eye on the earth.

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

"The power generation of 10 million square meters of solar panels in space is equivalent to that of a Three Gorges!"

"The new energy era has arrived, and the country plans to completely eliminate traditional fuel vehicles and vigorously promote new energy electric vehicles."

China's official propaganda channels, from TV news, newspapers, the Internet, etc., similar titles once again set off the entire China, and the detailed data quoted the data of the new solar power plant in space built by Fuyun Group.

When seeing the detailed data, whether it is China's state-owned enterprises, central enterprises, or China's private capital and power, everyone's eyes have already turned red.

Investing less than 20 billion can build a Three Gorges Hydropower Station in space. How huge the profit is, anyone can know that the current electricity price, even the civilian electricity price is now about 0.5 yuan per kilowatt-hour, and 100 billion kilowatt-hours of electricity are generated annually, which is nearly 50 billion in output value.

Even if this output value is further reduced, it is calculated as 0.25 yuan per kilowatt-hour, and the output value is 25 billion per year. Investing 20 billion, you can get back the investment in one year, and even make a profit. There is no better business in the world.

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

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

I don't know whether the calculation of this power generation is correct. Is there any data expert who can give me an analysis?
