In the outer space of the earth, a huge "Hercules" aerospace plane soared into the sky and directly entered the earth's orbit, and in the aerospace plane, Xie Feng and Duan Yanpeng, who were wearing the logo of the spacesuit of Fuyun Group, carefully piloted the aerospace plane towards the space port of the "Sky City" and slowly moored it.

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 put forward by Li Fu at the meeting, and China is now vigorously encouraging private capital to participate in the construction of the space industry, and now there are thousands of space farmland under construction and operation in space, of which only a small part belongs to the state, and most of the space farmland belongs to private individuals.

The space solar energy program is also a plan recently put forward by the state and vigorously encouraged and supported the development, the purpose is very clear, that is, to reduce the dependence on traditional energy, and more importantly, to reduce the dependence on foreign energy, so that Huaxia will not be stuck by others, and can not be controlled by others at critical moments.

As the most representative enterprise in the field of space in China, 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 the space station, space city, space farmland, spaceship, etc. are many solar panels composed of solar wings, these solar wings are actually designed to absorb solar energy into electricity, provide power for spacecraft, increase life and endurance.

In many cases, a pair of small solar wings is enough to provide very sufficient electrical energy for the spacecraft, because in space, the sunlight is very strong, without the weakening of the atmosphere, and it can be irradiated all day long, and the angle can be adjusted well, which can basically achieve vertical 90 degrees of irradiation and continuously provide electrical energy.

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

For example, the "Voyager 1" unmanned space probe launched by Uncle Sam on September 5, 1977, has been able to work intact until now, and has reached the edge of the solar system after decades of flight.

The reason why it can work continuously for decades is that the energy it originally carries is not enough to support, and the most important energy source is to use solar wings to obtain energy, plus relying on inertial flight itself does not consume energy, and regularly turns off the equipment to save energy, etc., so it has been almost half a century, and it can still connect with the earth.

Therefore, basically spacecraft, in addition to the one-time kind of initial opening, will have a pair of solar wings to obtain energy, especially large space stations, space cities, space farmland, etc., many of their shells are solar panels, which can continuously obtain solar energy.

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

The huge space plane slowly docked into the "Sky City" space port, the huge belly slowly opened, and the mechanical arm continued to take out the goods inside, and soon the stomach of the space plane was carried away.

Then the robotic arm began to load the cargo for the aerospace aircraft, and the square standard boxes that became one meter one by one were constantly transferred in, and the goods in these boxes were all crops produced by the space farmland of Fuyun Group, and the quantity was very large, and now it can not only meet the needs of the staff in the "Sky City", but also sell it to the country, and even directly transport it to the moon base.

In the Sky City, dozens of astronauts such as Luo Xiaoyao and Zhanfei were extremely busy at this time, and they were manipulating their mechanical arms to train each other to assemble the skeleton of the solar farm.

Solar farms are basically the same as space farmland, using large sky capsules to form a skeleton, and then subdividing them to install solar panels, and finally forming a huge solar farm, which can not only use solar energy to generate electricity, but also smelt asteroids by reflecting solar energy, and so on.

Dozens of astronauts in the virtual machine with the help of the virtual machine, with each other very tacit understanding, concentrate on the control of the mechanical arm, outside the city in the sky, a mechanical arm like a flexible hand, cooperate with each other tacitly, one by one to realize the planned space capsule in space continue to splic.

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

After the framework was completed, the astronauts replaced the astronauts, entered the space plane, broke away from the sky city to catch up, and then began to expand and refine.

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

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

"Start adjusting the angle!"

In the skeleton of the space capsule, Luo Xiaoyao controls the computer to calculate the angle between the solar panels and the sunlight pillar at this time, and then the engine on the space capsule will slowly adjust the angle between the solar panels and the sunlight, and the vertical irradiation can maximize the energy.

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

"Start converting to electricity."

Gently start, the data on the computer began to soar, 10,000 solar panels, the situation of each piece can be accurately grasped, an hour later, the detailed data of solar panel power generation in space will come out.

"The total power generation reached 12,948 kWh, which is almost 1.3 kWh per hour for almost every board, which is a bit amazing."

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

Generally speaking, if the light conditions are not bad, a square solar panel 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.

In addition, in space, solar panels can always be perpendicular to the sun, and at the same time, they can generate electricity 24 hours a day, and they are not affected by climate and seasonal changes, so the power generation efficiency is higher.

The 10,000-square-meter solar farm generates nearly 13,000 kWh of electricity in an hour, 312,000 kWh in 24 hours, and 113.88 million kWh a year.

You must know that the total investment of a Three Gorges Hydropower Station has reached more than 100 billion Chinese dollars just on the books, and if you count the cost of immigration and so on, the investment amount is even more huge.

However, at this time, to build a 10 million square meter solar farm in space, its cost is less than 20 billion, not even one-seventh of the Three Gorges, which was unimaginable before, the popularity of aerospace aircraft, so that the cost between space and space is getting lower and lower, the biggest cost is these high-tech solar panels.

As time passed, a huge mirror in space grew larger and larger, and soon the area exceeded 10 million square meters, and it was already visible to the naked eye on Earth.

"20 billion can build a Three Gorges hydropower station in space!"

"10 million square meters of solar panels in space generate electricity equivalent to one 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."

Huaxia's official propaganda channels, from TV news, newspapers, the Internet, etc., similar headlines once again detonated the whole of Huaxia, and the detailed data is to quote the data of the newly built solar farm in space of Fuyun Group.

When they saw the detailed data, whether it was China's state-owned enterprises, central enterprises, or China's private capital and power, everyone's eyes would have turned red all of a sudden.

Invest less than 20 billion yuan to be able to build a Three Gorges hydropower station in space, how huge the profit is, any person can know that the current electricity price, even the civil electricity price is now about 0.5 yuan per kilowatt-hour, and the annual power generation is 100 billion kilowatt-hours, that is, nearly 50 billion yuan of output value.

Even if this output value shrinks further, even if it is 0.25 yuan per kilowatt-hour, there is an output value of 25 billion yuan a year, and an investment of 20 billion yuan can be repaid in 1 year, and even there is a profit, but there is no better business in the world.

You must know that when the capital is very young, the return on investment is relatively high, but once the capital is hundreds of millions, it is already difficult to obtain such a high rate of return, not to mention the investment of tens of billions, and the profits are enough to make people crazy.

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