"Billionaire Elon Musk went into space on a SpecaX Dragon spacecraft."

"On May 20, Elon Musk, the founder of SpecaX, two SpecaX engineers and a wealthy man went into space on the 'Dragon' spacecraft, along with a Tesla roadster."

In Beijing, as soon as Lin Ju refreshed Twitter, he saw the news posted by Lao Ma 15 minutes ago, and he was wearing SpecaX's own customized spacesuit. Backing a blue Tesla Roadster.

It seems that there is no problem with the reduced Dragon spaceship.

The Falcon 9 rocket of the original World Line has almost never failed after the successful recovery experiment, and has only been interspersed with a few recovery failures, but it has never failed after more than 200 launches.

The same is true for the Dragon spacecraft, and the Crew Dragon spacecraft has had two iterations for seven or eight years before, so the Falcon 9+ Crew Dragon combination is extremely reliable both technically and historically.

Judging from the performance of Lao Ma tweeting every less than half an hour, he is probably very happy about this space trip, and even the Roadster sports car promised last year has also come up.

But the space agency thinks that the sports car is an empty shell, otherwise the center of gravity configuration of the Dragon spacecraft is a big problem, and there is no place to put the living materials, no wonder the old horse didn't open the door of the roadster.

"Elder She, there are more than five places for space training this year, right? The Aurora spacecraft can accommodate up to 11 people. ”

Academician She looked at Lin Ju and felt that the other party had something, and immediately raised his vigilance.

"That's impossible, 11 aerospace experts, but if something happens, it's a big trouble. At that time, there were internal regulations after the 63 empty disaster, and five people was already the limit. ”

As a military enthusiast, Lin Ju also knows that it was a crash that occurred in 2006 when the country was developing the Air Police 200 early warning aircraft for test flights, and the accident caused by the icing of the wings caused the loss of 34 first-class electronic experts in China, which is almost a heavy blow to the research force cut in half, otherwise the development speed of today's early warning aircraft can be much faster.

Lin Ju: "But our spacecraft is much stronger than the Y-8, and the reliability is completely different, and the June 3rd accident is also due to the fact that the aircraft was overloaded and did not meet the safety regulations at that time." ”

"There is a plan for how many people we will arrange to go up, what is the matter with Xinyuan?"

Academician She was too lazy to go around the bend and ask directly about the matter.

"What can we do...... Oh, there's a small thing, the third and fourth living modules have been built, and I'm going to increase the frequency of the Space Shuttle launches, and this is the schedule of four flights for the second half of the year, so I'll make a good arrangement. ”

Lin Ju's tone was flat, but Academician She didn't take the flight plan at all, and said while flipping it:

"I knew that when Musk went up, you wanted to go up too, it's always ...... Well? What is it? 100 passenger cabins! ”

Academician She was speechless in shock when he saw the frenzied passenger transport transformation plan, and kept shaking his head at a speed that did not match his age.

"Nonsense, nonsense! It's too dangerous, 113 people! You don't know how much risk you're taking, it's better to just go to space. ”

He originally thought that Lin Ju was bewitched by someone and wanted to go to space again, who knew that he was actually going to send more than 100 people at one time, he didn't want to calculate the success rate, as long as it was not 100%, the Aviation Development Commission would not dare to approve it!

Even if it is a 0.001% risk, it is more than 100 lives, and this level of accident is to be reported to the whole country and the central government will set up a team to investigate, and the impact is incalculable.

Lin Ju saw Academician She's resolute refusal, although he had expected it, he was still a little disappointed, and it seemed that the resistance was indeed not small.

"That'...... Just me up? ”

"That's pretty much it...... Wait, you're getting me in, hey! "Academician She only hated why the big guy didn't bring himself when he went abroad, and no one in the Aviation Development Commission could suppress Lin Ju except him, and every time he came to the capital, there was no trivial matter.

"What's in the bag? Let's talk about it, right? ”

"Huh? That," Lin Ju took out the remaining documents from his open briefcase.

"Chang'an University of Science and Technology fooled the Shuchuan government and prepared to engage in space power stations and small projects."

“……”

Although Shuchuan eats the transfer payment of the central government every year, it has never fallen behind, and the independent power that has been greatly enhanced after the restructuring of the fiscal and tax relations between the central and local governments is beginning to let go of itself.

The space power station is not a novel concept, Aramco first engaged in it in the 70s, but it was withdrawn due to cost factors, and it was picked up again after entering the new century, but countries are also following suit.

In 2008, space-based solar energy was included in the national key research plan, and in 2014, the state released the development plan of space power station and the demonstration report of key technology system planning.

In 2018, the "day-by-day" plan was launched, and in 2022, an experimental space-based solar power generation and receiving device was built in China, and it is expected to build a space power station with a power generation comparable to that of the Three Gorges in 2035.

Compared to terrestrial power generation, space power generation has many advantages.

The first is the radiation intensity, without the interference of the atmosphere and clouds, the average radiation intensity of the solar panels of the space power station operating in a 36,000-kilometer geostationary orbit is 10 times that of the Earth;

In addition, satellites in geostationary orbit can receive sunlight around the clock, and are completely unaffected by the earth's rotation and weather, and can continue to supply power throughout the year.

According to some previous demonstration reports of various countries, the power generation efficiency of ground solar panels is about 8% to 12%, while the efficiency of space power stations can be 35.5%.

There are two main means of transmission to the ground: microwaves and lasers.

Compared with lasers, microwaves are not attenuated by the atmosphere, and the microwave conversion and collection efficiency from 1 to 10 GHz can reach 90%, and the overall efficiency can still reach 32%, which is 2.5 to 4 times the efficiency of the ground.

Professor Ding Biyun of Chang'an University of Science and Technology is mainly engaged in this research in China, and they are also doing the space power station project in China of the original World Line.

Perhaps affected by the changes in the world line, they found the Shuchuan government, which was bent on finding a new life because the artificial moon project was rejected, and promoted their own space power station plan.

According to the prospect of their sales plan, if a 1,000-ton power station with a power generation capacity of 160 megawatts and an area of 400,000 square meters is built in space, it can provide 10% of the installed power generation capacity of Chengdu, and because it is all-weather power generation, it can actually reduce the installed capacity of the ground by 15% to 20%.

Although the current cost of high-power solar panels is still close to 1 million yuan per square meter, if so many solar cells with a thousand times the existing production capacity are mass-produced, the price can be reduced to an incredible level, and the overall power generation part of the cost is only 4 billion yuan, and the overall space power station cost is less than 10 billion yuan.

Such a space power station can generate 1.4 billion kilowatt hours of electricity per year, transmit about 1.26 billion kilowatt hours to the ground, and directly generate nearly 700 million yuan according to the power supply standard of 0.55 yuan per kilowatt-hour, but considering the reduction of losses caused by all-weather power generation, it can actually save twice the electricity bill.

Converted into thermal power, it saves 860,000 tons of coal and 2.2 million tons of carbon dioxide emissions every year.
