June 7, Qiongzhou, Wenchang Space Launch Center.

At noon, at the busiest station 1, a Xinyuan-3 rocket flew into the sky dragging a long flame into the sky.

Ding Biyun, who was standing a few kilometers away from the launch station, looked up at the sky and watched the big rocket disappear into the sky.

"Teacher Ding, Teacher Ding!"

Xiong Cheng ran over with a shout, his white shirt soaked with sweat, and with his dark skin and hard hat, he looked like a working construction worker.

"Teacher Ding, it's time to take a group photo, let's go over quickly."

"Thank you Professor Ding for your contribution to the cause of environmental protection and the promotion of clean energy!"

The receiving antenna is not used for the time being, and it is prepared for space networking when a large number of space power stations are running in the future.

In order to produce special solar cells, Xinyuan, the Space Bureau, and the Rongcheng government cooperated with the largest photovoltaic company in China to establish Huaxin Space Energy Company, and under such a large number of orders, the price of K2 batteries successfully dropped from 260,000 yuan per square meter to an astonishing 9,100 yuan, with a total order value of 3.2 billion yuan.

And behind them, a banner was also draped in red:

The entire space power station plans to use 1,700 K2 solar cells, with a total area of 357,500 square meters, a power generation area of 348,500 square meters, a maximum power generation of 174.25 megawatts, an average power generation capacity of 168 megawatts, only 973 tons of power generation, and a total weight of 1,120 tons.

Of course, the actual cost of launching and testing from Chiwu No. 1 to Chiwu No. 3, ground receiver construction, power grid renovation and personnel is actually counted, and the operation of Chengdian No. 1 has almost touched the edge of 30 billion from 0 to Chengdian 1.

Ding Bijun looked at the source of the discordant sound, and skipped it directly after catching a glimpse of the NHK logo.

"I appreciate their creativity and imagination, it's a great idea, and I think it's going to be a huge help to the environment and the energy revolution like space power."

When he came to the stage under Xiong Cheng's pull, he was immediately surrounded by a big red flower, and was crowded in the center by a row of people to take a group photo.

"Ding ......"

The subsidized space power station project is not a loss at all, and the daily project has also derived a series of important technologies, of which power generation is only a small part.

If all goes well, Chengdian-1 will be assembled in low-Earth orbit in December, and then actively upgraded to geosynchronous orbit, and will begin to provide clean electricity to the ground after March 2019.

"Professor Ding, what do you think of the Hexagon's accusation that microwaves will cause serious harm to the human body?"

However, after the arranged reporters were satisfied, the other media, especially the foreign media, were not so easy to dismiss.

"Okay, okay."

It's not just people from the space agency, but also officials from the governments of Rongcheng and Shuchuan, as well as people from several solar energy companies, the Environmental Protection Bureau, and the State Grid, which can be called a super hodgepodge.

"Any excess of electromagnetic waves will cause harm to living things, so our receiving antennas are selected in uninhabited areas and strictly managed."

However, this is not what the middle-aged reporter wants to hear, and he continues to ask:

"Warmly celebrate the successful launch of the main frame of the 'Chengdian-1' space power station"

"Professor Ding, a project has opened for us for half a year, thank you!"

"Can you explain the Qinling Genocide caused by Chiwu 3, there is information that the villagers of several villages were forced to move out because they could not bear the microwave."

The "haha......" reporter is a witty-looking middle-aged white man who doesn't seem to be that aggressive.

The construction cost of the main framework was 2.5 billion yuan, and the total price of the seven launches and missions was 15.5 billion yuan, not counting the verification experiments in the early stage, Chengdian No. 1 spent 21.2 billion yuan, which was 6% more than the rough estimate of 20 billion yuan.

Ding Biyun still maintained his head up, as if he was worried that the rocket would suddenly fall.

"Some people say that this mirror will be blown away by the sun, what do you think?"

The congratulatory words almost drowned Ding Biyun one after another, and finally waited for them to finish speaking and then came to his one-man speech, but this was not over, in the last period of time was the media conference, and the reporters who were looking forward to it had long been impatient.

Chengdian No. 1, the official name of the space power station proposed by a committee in Rongcheng at the beginning, has gone through nearly two years of wild running, and finally started construction today.

After the completion of the dedicated semi-enclosed giant parabolic receiver in Rongcheng, the ground will be able to receive 155 MW to 160 MW of electricity.

"This is all false news, you have already asked it, the Bloomberg reporter please say, I hope you will not repeat the rumor that Chengdian-1 is a secret weapon, there is no secret weapon in space."

Such a lively scene made him a little uncomfortable after staying in the Qinling Mountains for a year, and he struggled to cope with the microphones stretched out, carefully recalling the manuscripts he had prepared before.

The main frame of Chengdian No. 1 weighs 147 tons, of which the frame part is 90 tons, about 40 tons are antenna quality, and the remaining 10 tons are all dense heat sinks.

"Professor Ding, NACA is also working on a similar artificial sun project, do you have any thoughts on your peers?"

"Professor Ding, you are our great hero!"

Ding Biyun didn't dare to be vague about this question, after all, such a high-energy and dense microwave is indeed terrifying, and there can be no one when the receiving antenna of Chengdian No. 1 is working.

"Professor Ding, is Chengdian-1 some kind of secret weapon?"

After all, it is about 170 megawatts of power input, even if the microwave conversion efficiency is as high as 99%, the wasted part will still generate huge heat energy, and the only way to solve it is to desperately put on the heat sink, which is all over the microwave antenna.

Of course, Ding Bijun remembers "John Sun", that super large mirror I heard that NACA is really serious, and he has been concentrating on the day-by-day project, and he doesn't know much, but it doesn't prevent him from saying a few beautiful words.

What has just been launched is the main frame of Chengdian-1, which provides a platform for solar cells to attach to, and is equipped with two super-large microwave antennas, which are used to transmit and receive microwaves respectively.

According to Xinyuan's plan, Chengdian-1 needs a total of six launch missions, namely the four-engine Xinyuan-3 to send more than 900 tons of solar cells, and then the Storm and the soon-to-be-launched Great Wall 1 will carry out the in-orbit assembly mission.

Fortunately, the day-by-day project has received strong attention from above, and the ground construction Rongcheng government has solved part of it, and the real capital consumption is about 26 billion yuan, of which 11 billion yuan is subsidized by the central government, and the real local capital is only 15 billion yuan.

Both super antennas are folded and have a maximum transmit power of 180 MW and a maximum receive power of 100 MW.

"Uh...... In a sense, it is indeed a super-large sail, and in addition to shining on Earth, NACA can also use it to propel a probe or spacecraft to Mars. ”

Ding Biyun did not give a positive answer, in fact, this problem is very serious, the "artificial sun" in Rongcheng is because of the need to frequently correct the orbit to offset the displacement caused by the light pressure, it is not difficult but it is a troublesome matter.
