Universe dominance

In the outer space of the earth, a huge "Hercules" aerospace plane soared into the sky and entered directly into the orbit of the earth. Inside the aerospace plane, Xie Feng and Duan Yanpeng, wearing space suits with the logo of Fuyun Group, drove carefully The aerospace plane slowly parked towards the space port of the "City in the Sky".

This time their mission is to transport a large number of solar panels to space and prepare to build a large solar farm in space.

This plan was also proposed by Li Fu at the meeting. China is now strongly encouraging private capital to participate in the construction of the space industry. Currently, 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 belongs to private individuals.

The space solar energy plan is also a plan that the country has recently proposed and strongly encourages and supports its development. The purpose is very clear, which 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 every satellite has a pair of solar panels like wings, as large as a space station, space city, space farmland, spaceship, etc., they all have many solar panels. The actual purpose of these solar wings is to absorb solar energy and convert it into electrical energy to provide power for the spacecraft and increase its life and endurance.

In many cases, a pair of small solar wings is enough to provide a very sufficient electrical energy for the spacecraft, because in space, the sunlight is very strong, without the weakening of the atmosphere, and it can shine all-weather, adjust the angle, basically it can Achieve vertical 90-degree illumination and continuously provide power.

In addition, the spacecraft relies on inertial flight most of the time in space, and generally consumes basically no energy at this time, so a pair of small solar wings is enough to provide energy for the spacecraft and operate for a long time.

For example, the "Voyager 1" unmanned outer solar system space probe launched by Uncle Sam on September 5, 1977, is still able to work perfectly 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 operate perfectly 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, plus relying on inertial flight itself does not consume Energy, shutting down equipment regularly to save energy, etc., so almost half a century later, it is still able to connect with this side of the earth.

So basically all spacecraft, except those that are disposable when first launched, will have a pair of solar wings to obtain energy, especially large space stations, space cities, space farmlands, etc. Many of their outer shells are solar power panels, which can Continuously obtain solar energy.

However, it seems that there has never been a really large-scale solar farm specifically designed to capture solar energy and convert it into electrical energy in space, so Fuyun Group has set another historical precedent.

The huge aerospace plane slowly parked in the "Sky City" space port. Its huge belly slowly opened, and the mechanical arm continued to take out the goods inside. Soon the belly of the aerospace plane was empty.

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

In the Sky City, dozens of astronauts such as Luo Xiaoyao and Zhan Fei were extremely busy at this time. They were controlling the robotic arms to train each other to assemble the skeleton of the solar farm.

A solar farm is basically similar to a space farm. It uses large sky capsules to form a skeleton, and then continuously subdivides and installs solar panels, eventually forming a huge solar farm, which can not only use solar energy to generate electricity, but also reflect solar energy. To smelt asteroids and so on.

With the help of the virtual machine, dozens of astronauts cooperated with each other very well and concentrated on controlling the mechanical arms. Outside the Sky City, the mechanical arms were like flexible hands, cooperating with each other and realizing each one. The planned space capsules are constantly being spliced ​​together in space.

Soon, a huge frame appeared in space, and then this frame was composed of space capsules. Each space capsule had an engine. When these engines were started, the huge frame gently floated away from the sky. The city slowly moved into its own orbit.

After the framework was completed, the astronauts changed into astronauts, entered the space plane, left the sky city and caught up, and then began to continuously expand and refine.

Compared with building space farmland, building a solar farm is much simpler, because you only need to subdivide it into one-meter-long squares, and then install solar panels.

Soon, a huge solar farm with a length and width of 100 meters was assembled. With the help of numerous robotic arms, the astronauts' work became much easier.

"Start adjusting the angle!"

In the skeleton of the space capsule, Luo Xiaoyao controlled the computer to start calculating the angle between the solar panels and the sun's light beam at this time. Then the engine on the capsule would slowly adjust the angle between the solar panels and the sun's rays, so that vertical irradiation could be achieved. Get maximum energy.

The engine on the space capsule slowly rotated, and each solar panel began to move slowly. Soon, the sun's rays illuminated each solar panel vertically.

"Start converting into electricity."

With a gentle start, the data on the computer began to soar. The conditions of each of the 10,000 solar panels could be accurately grasped. An hour later, detailed data on the power generated by the solar panels in space came out.

"The total power generation reaches 12,948 kilowatt-hours. Calculated, each panel generates approximately 1.3 kilowatt-hours per hour. This power generation efficiency is a bit astonishing."

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

Generally speaking, if the lighting conditions are good for civilian solar panels on the earth, a one-square-meter solar panel can generate about 0.5 degrees of electricity a day. However, when exposed to the sun, the power generation efficiency reaches dozens of times that on the ground. .

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

A 10,000-square-meter solar farm generates nearly 13,000 kWh in one hour, which is 312,000 kWh in 24 hours, and 113.88 million kWh in a year. You must know that the total power generation of the Three Gorges Hydropower Station in a year is about 100 billion kWh. If calculated in this way, The power generation capacity of almost 10 million square meters of solar panels can be used as a Three Gorges Hydropower Station.

You must know that the total investment in a Three Gorges Hydropower Station is more than 100 billion Chinese dollars, which can be calculated on the books alone. If immigration and other expenses are included, the investment amount will be even greater.

However, at this time, a 10 million square meter solar farm needs to be built in space. Its cost is less than 20 billion, which is less than one-seventh of the cost of the Three Gorges. This was something that was unthinkable before. The popularity of space shuttles has made the cost of traveling to and from space getting lower and lower. The biggest cost is these high-tech solar power panels.

As time goes by, a huge mirror in space becomes larger and larger, and soon the area exceeds 10 million square meters, and it can already be seen with the naked eye on 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 the 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., headlines like this have once again detonated the entire China, and the detailed data quoted the newly built solar energy plant in space built by Fuyun Group. Power plant data.

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 turned red.

It is possible to build a Three Gorges Hydropower Station in space with an investment of less than 20 billion. Anyone can know how huge the profit will be. The current electricity price, even for civilian electricity, is about 0.5 yuan per kilowatt hour, which generates 1,000 yuan a year. Yidu, which is an output value of nearly 50 billion.

Even if the output value shrinks further, even if the electricity is 0.25 yuan per kilowatt-hour, the output value is still 25 billion yuan a year. With an investment of 20 billion yuan, the capital can be recovered in one year, and there is even a profit. There is no better business than this in the world. .

You must know that when the capital is very small, the return on investment is relatively high, but once the capital reaches hundreds of millions, it is already difficult to obtain such a high return, let alone an investment of tens of billions, in which the profit is It's 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 eager to invest every last penny of their own money.

I don’t know if the calculation of this power generation is correct. Is there any data emperor who can provide an analysis?
