Chapter 796 (2/2)

After hearing this news, Jiang Chen just got off the plane and didn't even return home. He went directly to the future man building. He found Kelvin in the Research Institute and ordered the technicians of the research institute to draw up the engineering concept map.

The dark blue light particles are projected in the sky, and the space elevator directly to the synchronous orbit looks like an umbrella that is stretched out. One side is a long and narrow ”cable” that runs through the stratosphere transfer station to the ground, while the other side is a wheel shaped space station, which serves as the living and working space of outer orbit, and also serves as the ”balance weight” to control the center of gravity of space elevator in synchronous orbit.

”The ability of graphene track to bear tension is much greater than that to bear pressure. Compared with breaking by its own gravity, the risk of orbit collapse by self weight is greater. In order to avoid the space elevator from being crushed by its own weight, our engineers came up with an idea to drop 36000 kilometers of cable from the space station in synchronous orbit to the ground. At the other end of the cable, a wheel shaped ”counterweight” is designed. The balance weight with the center of gravity behind the space station rotates in the same axis at a constant speed, and exerts an outward tension on the cable through centrifugal action, so as to avoid the pressure of our orbit from bearing the self weight ”

” at the same time, the wheel like balance weight itself will also be a part of the space station, providing additional living and working space for the space station. ”At this point, Kerwin's face showed a trace of genuine pride.

If we put it a year ago, before the breakthrough of graphene materials, such a design concept would undoubtedly be ridiculed as wishful thinking. Just like when American physicist Pearson put forward the concept of space elevator in 1970, peers and the media gave him unfriendly suggestions, such as ”write science fiction instead”.

However, today, the design of ”balance weight” will become the construction standard of space elevator in the future, and taclewin will become one of the founders of the interstellar age of earth civilization because of this design.

he really has the capital to be proud of.

Although the future space elevator also has a structure similar to the ”counterweight”, the specific design scheme is not mentioned in the information provided by Jiang Chen to the aerospace science and technology center. What he brings from the end of the world is only the front-end technology required for the construction of the space elevator and the elevator base.

< BR, how much of the engineering cost did Wen mention. This space elevator is good for everything, but the cost is a little bit not user-friendly. Japan's Dalin construction company, which built ”sky trees” for Tokyo, announced the ”2050 space elevator construction plan”. The project cost is estimated to be 9.5 billion, almost one twelfth of his quoted price.

Of course, one of the reasons is that the former just talks casually.

”From orbit to the space station, the total project cost is estimated to be 120 billion dollars.”

”No problem. I'll find a way to solve the problem of capital. In the future, Renzhong will cooperate with you to adjust the production capacity. Starting construction tomorrow, can we do it? ”

however, Jiang Chen's reaction was beyond Kelvin's expectation, let alone hesitation. When approving the construction, the chairman didn't even blink his eyes. This NIMA is not two thousand dollars, but it's 200 billion dollars.

Kerwin was stunned and lost his words for a time.

”What's the problem?” Jiang Chen asked suspiciously when his subordinates did not speak.

Jiang Chen's question immediately made Kerwin come back to his senses. He stood at attention as if he had been beaten with chicken blood, and exclaimed excitedly.

”No, there are no problems to ensure the completion of the task”

although it is not clear why he suddenly reacted so excited, Jiang Chen was naturally very happy to see his subordinates so energetic, and immediately patted him on the shoulder.

”Then go,” to be continued.
