Technological power starts with upgrading lenses

Seeing the message Fang Qiming forwarded to her, Zhang Qing's expression visibly stiffened for a moment, but in the end she couldn't help but click on the link and watched the video inside.

Until the video ended, she still stood there, staring blankly at the last frame of the video without knowing what she was thinking.

A monk happened to walk by and seemed to understand something after seeing her reaction. He just sighed softly and saluted her back with one hand.

They have seen too many tourists trapped in love.

"Sister, why are you in a daze?"

At this moment, a sound like a silver bell rang. Zhang Qing looked up and saw her cousin blinking at her curiously, so she quickly locked the screen of her phone.

"nothing."

"Is it something about work again?" Lin Xue pretended to be dissatisfied and said, "When I came out with you, didn't we clearly agree not to talk about work and just have fun? Don't be such a spoiler!"

"Um……"

"That's right!" Lin Xue took Zhang Qing's hand and said excitedly, "You can't guess what I just did!"

"What?"

"There is a suspended toilet on the top of this temple. Netizens call it the toilet in the sky. You can't imagine how exciting the last suspended toilet was in the temple with the highest altitude! Come on, let me take you to try it!"

Zhang Qing "..."

Although Lin Xue invited him in every possible way, Zhang Qing decisively rejected this tasteful and shameful proposal.

The two walked to the observation deck opposite and admired the temple built on the cliff for a while, then came to the tarmac to wait for their flight.

It has to be said that this trip to Xizang made Zhang Qing more intuitively aware of the changes that Kangchi and Longteng Group have made to the land of China over the years.

For example, although places like Zizhu Temple are only 37 kilometers away from the county seat, if tourists wanted to come here in the past, they had to drive carefully along the steep cliff road for two hours.

But as Songkongtong has planned a special tourist line here, tourists can fly to this majestic temple in less than ten minutes by Yunhe.

And transportation convenience is actually just the tip of the iceberg of all changes.

To be honest, Xizang has never been considered poor. It can even be said to be rich.

Zang people often have hundreds of yaks worth tens of thousands, and being a millionaire per capita is no joke.

But the problem is that having money here does not bring actual convenience to life.

The remote geographical location means that even the most common vegetables here are several times more expensive than in the outside world, not to mention resources such as medical care, education, and entertainment.

The money is worthless, let alone used, and the primitive living conditions are difficult. So what if the average per capita is tens of millions?

But since Song Kongtong began to vigorously deploy in Xizang, Xijiang and other places, their various materials have finally been able to circulate quickly, and the long-term high prices have begun to drop significantly.

At the same time, the outside world can also buy truly green and healthy mountain specialties at cheaper prices. As more and more companies set their sights here, the local economy has been further revitalized, and a large number of natural resources have begun to be utilized.

After Zhang Qing returned to DQ County, the sky had begun to darken, and the entire county began to gradually light up, becoming more and more vibrant and prosperous.

"Actually, he is the one who should come here to see the results of his hard work..."

"who?"

"A dork."

"hold head high?"

"I suddenly felt that maybe people like him shouldn't be tied down by the love between children. I was too selfish and wishful thinking..."

"No way?!" Lin Xue seemed to have discovered something terrible, and she quickly exclaimed, "Sister Qing, are you actually in heat, or do you still have unrequited love!? Tell me which blind man you are!"

"Stop talking nonsense!"

"Holy shit, you're still defending him? Do you know this is dog-licking behavior?"

"You go!"

…

After briefly inspecting the Ming Dynasty Deep Space Parts Manufacturing Base in Luzhou, Kang Chi quickly returned to Dongyang. Director Ge had sent someone to hand over the blueprints of the Snowstorm to him three days ago. Academician Fu's team is now working on To carry out all-round study and reference on drawings, in addition to learning from each other's strengths, the more important thing is to keep pace with the times.

Academician Fu is quite good at reverse engineering technology, not to mention the full set of drawings that are being fed to his mouth. The only thing that needs to be careful is that there may be a 'blade' in it, so Kang Chi is not too involved in their work. The design work mainly focused on Yan Hui.

After the engine has been taken out by Kangchi alone, the rocket itself is not difficult. Even if the equipment is customized and purchased with existing technology, a rocket that can be launched normally can still be produced.

But Kangchi is obviously not satisfied with this, so mastering and upgrading liquid hydrogen storage technology has become the next problem.

Liquid oxygen and liquid hydrogen rockets have many advantages such as non-polluting, renewable, and high specific impulse. It is currently recognized as the fuel with the highest energy density except nuclear fuel. The energy density of up to 120-142MJ/kg is 2.5 times that of methane. Oil and gas 3 times,

But it also has a relatively big disadvantage, that is, the energy density here refers to the mass energy density, that is, for the same one kilogram, hydrogen has the most energy, but if it is replaced by volume energy density, hydrogen will be instantly killed by most fuels. .

The low volume energy density means that a larger fuel tank is needed, and hydrogen is volatile and needs to be kept in liquid form at -253 degrees Celsius.

The extreme storage conditions have become the biggest bottleneck in the development of liquid hydrogen energy. This affects more than just ordinary storage and transportation, and also places extremely high demands on the design of the rocket itself.

After all, the issues that need to be considered on the ground must also be considered on the rocket.

Therefore, liquid oxygen and liquid hydrogen rockets usually require larger fuel tanks, more insulation materials and equipment, which greatly reduces the strength and lightness of the rocket, and reduces the rocket's payload.

This can be seen from the huge orange fuel tank carried by the old M space shuttle.

"President Zhuo has reached a formal cooperation with Dongfang Electric." Yan Hui reported the progress and handed the cooperation agreement to Kang Chi. "They will provide us with the most advanced hydrogen and oxygen production equipment, but the subsequent transportation, storage and refueling still need to be solved by ourselves..."

"Storage and transportation are actually the same." Kang Chi interrupted Yan Hui slightly, "How is the negotiation progress with Shengyuan Environmental Protection?"

"It's a bit troublesome." Yan Hui said with difficulty, "Because we want their technology rather than equipment, they are more resistant to it, and they are not as sensible as Blue Arrow Aerospace."

"Plus, they are a listed company, and the transfer process of core technology is quite troublesome. President Zhuo means to directly acquire them, but the problem lies in their attributes as a listed company. The time for the merger and acquisition will definitely not be short..."

"Then forget it." Kang Chi waved his hand directly,

"I will do it from scratch, and the progress will be synchronized with you in real time. You will be fully responsible for building the main body of the booster. In addition, the first engine will be handed over to you in about a week, and the rest will be in place within a month. We will strive to launch and recover the booster within three months."

"Three months!??"

Yan Hui's eyes widened immediately.
