The solution given by the Kyushu Blue Arrow team is, to put it bluntly, a mini version of the Dyson ball in a low-end version.
Technical demonstration has proven that this is feasible, unlike controllable nuclear fusion, which is still struggling to achieve a breakthrough from 0 to 1. Otherwise, there would not be so many countries launching their own space power station plans, although most
The country is all about PPT, and the only ones that can really play well are rabbits and eagle sauce.
We know that this thing cannot be achieved overnight. It will take ten years, twenty to thirty years or even more to achieve it.
But the technical feasibility has been verified. If you really want to do it, it means you have to schedule it now, otherwise it will always remain on paper.
What's more, even controllable nuclear fusion has not made a breakthrough from 0 to 1 and has been struggling. The technical feasibility of this space power station has been verified, and there is no reason not to do it.
The technology of space power stations mainly involves three major aspects: first, sending it to space for assembly, second, establishing a ground receiving station, and third, operation and maintenance. To realize these three major aspects, dozens of technical branches are needed to complete.
In general, the focus now is to promote technology upgrading and engineering.
At this time, Tian Jiayi, who was sitting in front of the computer in the study room, quoted Fang Hong’s words: “The technical feasibility has been verified, but has the economic feasibility of the space photovoltaic power station been verified?”
After her question was raised, after a while, another participant answered her question: "According to our calculations, it is economically feasible. Let me start with the conclusion. The ratio of benefits to costs of space photovoltaic power plants can reach
1.9, that is, the return on investing 1 yuan is 1.9 yuan.”
When Fang Hong, who was outside the camera, heard this, he realized that he could earn 9 cents from investing 1 yuan, and the profit rate reached 90%. After allocating it to various levels of industries, the final net profit rate would be at least over 35%. It was a bloody profit.
of trading.
At the same time, the participant said: "The biggest part of the space photovoltaic power station is the modular production of solar panels. The huge demand will greatly spread the cost, but it is the cheapest part of the entire space photovoltaic power station."
"Another big cost is rocket transportation. This is our specialty of Kyushu Blue Arrow. Although the 'Blue Arrow-1' that is about to be tested is a traditional rocket, our ultimate goal is to be recyclable and reusable. By then, it will be launched
Costs will be significantly reduced.”
After a while, Xiang Lanzhi, who was present at the meeting, said: "According to our plan, the launch of the major components of the space photovoltaic power station will not be directly transported to the geostationary orbit for installation, but will be continuously launched through recyclable rockets.
The original modules of each major component are sent to low-Earth orbit. Therefore, we need a space station of our own to operate in orbit."
"In low-Earth orbit, there will be a group of spacecrafts specially loaded with fuel waiting. There will be a space refueling station here, which will be used part-time by the space station, and then the space photovoltaic power station module components will be transported back and forth between low-Earth orbit and medium-low orbit. Upon arrival,
After the low orbit, it will assemble and unfold the solar panels by itself, and then use its own electric propulsion engine to send itself to the final geostationary orbit to complete docking and assembly with other modules."
The previous participant said again: "With the entry of our Kyushu Blue Arrow and the solution of recyclable rocket technology, the overall launch cost will be reduced by half."
He gushed to the sponsor's father: "And for a project as big as the space photovoltaic power station, as long as it is confirmed to start, the load required must be in the 10,000-ton level, and the required launch requirements are hundreds or thousands of times. Such a large
The commercial launch demand will further expand the scale of the entire aerospace market on the basis of existing commercial satellite launches, and the cost will plummet."
"Our final economic feasibility report calculated that the cost of a space photovoltaic power station is in the range of 300 yuan to 600 yuan per 1,000 kilowatt-hours of electricity, which is not much different from other current clean energy sources, or even lower than that.
, and it can also drive a bunch of industries, and the GDP multiplier is very impressive."
Outside the camera, Fang Hong said nothing, but he was thinking about it in his heart.
Compared with this super project that looks extremely sci-fi, many prerequisites need to be solved. In terms of economic feasibility, such as the development of photovoltaic technology, in the memory of the past life, it is not without reason that the country is crazy about promoting the development of solar photovoltaic technology.
.
In such a short period of time, the photovoltaic industry has reached overcapacity, leading the world in photovoltaic technology. Various photovoltaic panels are laid everywhere in the northwest of the country. The major photovoltaic industry-related companies are Longji, JinkoSolar, and Tong.
Ventilation, Trina Solar and other manufacturers are experiencing huge losses.
The vigorous development of these companies is not only to meet the current demand for clean energy alternatives, but also to transform and upgrade the manufacturing industry. Another aspect is to reduce the cost of photovoltaics and lay the foundation for future-oriented space photovoltaic power stations.
Based on the current situation, it is natural to develop a large number of companies related to the photovoltaic industry. Not only must they survive, but they must also develop into world-class photovoltaic companies.
In Fang Hong’s memory of his previous life, domestic development in the photovoltaic field was indeed leading the world, accounting for more than 70% of the global market share, so that Europe and the United States frequently suppressed and even banned the import of photovoltaic products from the Greater China market, because foreign
Photovoltaic companies simply cannot compete under normal market competition rules.
One of the answers to the question is coming out right now.
To support the development of the photovoltaic industry and allow domestic photovoltaic companies to survive and develop, we must first roll out photovoltaics on the ground and reduce costs first, and then create a group of world-class photovoltaic giants, and then upgrade and develop more advanced ones.
Photovoltaic technology.
Solving these problems will not only solve the current problems, but also foreshadow the future.
In the future, when the super project of space photovoltaic power station is officially promoted to enter construction, a complete set of photovoltaic industry systems have been successfully established behind it to provide strong support. As soon as the project is launched, related photovoltaic production orders are filled. At that level
The demand from one photovoltaic manufacturer is absolutely unbearable, and cost amortization has further plummeted.
What Kyushu Blue Arrow wants to solve is to reduce launch costs and light up rocket recovery technology.
As the video conference ended, Tian Jiayi turned his head and looked at Fang Hong: "The space photovoltaic power station, shall we, Star Capital, follow or not?"
Once it is established and followed up, it must be an epic engineering project, and the minimum measurement unit of funds required to be invested is "hundred billions" level.
Fang Hong said without hesitation: "Of course I want to follow. The technical feasibility has been verified and the economic feasibility has been verified. Why not follow?"
After a moment of pause, Fang Hong reviewed the memory information from his previous life in his mind, and at the same time ordered: "We are planning to establish a space photovoltaic power station system project, which will be called the 'Sunday Project'. The goal is to build the first experimental one around 2O25."
The first commercial-grade space photovoltaic power station will be built around 2035, and will become the mainstream of power generation around 2050."
Fang Hong looked at the beautiful assistant and added: "Based on the 'Daily Project' plan, Stars Capital will now super double its current investment in the new energy industry, especially the photovoltaic industry, and must achieve leadership in photovoltaic technology.
It’s way ahead of other countries.”
Speaking of this, Fang Hong smiled calmly: "How to make money in the future? There are many ways, including taking orders from other countries and helping them build space power stations, or going to countries and regions with poor economic strength to go to them.
Establish a ground receiving station to provide power to the area, directly export light energy, and send electricity wherever it is needed."
Tian Jiayi was taking notes. At this moment, Fang Hong suddenly added: "By the way, according to what Xiang Lanzhi just said, the space light energy power station has two transmission methods. One is to transmit to the ground through microwaves.
, and the other is delivered to the ground by laser."
Hearing this, Tian Jiayi nodded and said: "Well, I suggested to Lanzhi to use microwaves. The laser transmission method has potential orbital ground military strike capabilities. She is worried that it will cause political risks internationally..."
Fang Hong said succinctly before she could finish her words: "Then it's even more important, and it must be done. We have always walked on two legs. The microwave method is for commercial and civilian use, and the laser method is for military use. Both of them must be high.
The laser transmission method is done secretly and is top secret.”
