Chapter 1067 Renovation Plan

Back on the ground, Zhang Hao quickly held a high-level meeting of Dayang Group. A few words will solve the problem of selling the small spaceships found on the moon base and left by the Xuanhuang civilization.

In fact, everyone has already had such an idea about selling the spaceship.

With the recent development of space, the financial pressure is extremely high, and it is time to 'open source'. Especially now that we have both cooperation and competition, holding good things in our hands and not releasing them is not conducive to long-term development.

But when it will be sold and what the price will be, it has not been able to reach a consensus; however, the general conditions have already been established.

Now under this opportunity, everyone quickly finalized the transaction plan: the price of the spaceship is 8.5 billion Lingyuan, which can be paid in installments, but the down payment must exceed 30%; if you want to buy two spaceships at the same time, please pay the full amount for one first Besides.

The price of the spaceship is 8.5 billion spirit stones, which sounds a bit high, but the actual situation is not high - after all, it is left by advanced civilization, and the smallest spaceship has a diameter of more than 100 meters, and has a strong transportation capacity. This transportation capability is invaluable when China's space development is just starting.

Before that, everyone's transportation costs in space were calculated in terms of 'grams'. For example, the cost price of materials launched by Dayang Group from the ground to space is as high as 4 yuan per gram. The purchasing power of the currency of Dayang Group is not small. One yuan can buy five catties of brown rice, which is equivalent to the three-day ration of an ordinary family.

The transportation cost from the orbit of the Tianyuan star to the moon is as high as 2 yuan per gram if it is transported by rocket. Thinking about industrial construction, it is often calculated on the basis of millions of tons, and the transportation cost of 2 yuan per gram is unbearable.

After the spacecraft is enabled, the cost of transportation between spaces will be greatly reduced, and can be reduced to a thousand dollars per ton. The main reason is that the cost of nuclear fuel for the spacecraft is high, and the maintenance cost of the spacecraft is also high.

In short, as space technology becomes more and more perfect, as Xuanhuang Group and Hetu World also plan to make a difference in space, it is imperative to buy spaceships from Dayang Group.

Fortunately, Dayang Group has already considered this point, and Zhang Hao is also very clear: the current situation of Tianyuanxing is different from the previous Earth.

In the past world, no alien threat was found, so all parties tried their best to fight back, and all good things were hidden, and they were afraid that the neighbors would find out.

But this world is different. We are facing a powerful threat. Under this threat, we have to do everything possible to develop and become stronger. Mutual cooperation is inevitable; or it is the only choice.

But cooperation is cooperation, and brothers have to settle accounts clearly.

After the matter of the spacecraft is settled, everyone immediately proceeds to the next meeting: Venus development!

The discovery of a large number of high-grade ores on Venus was not previously thought of. Before that, everyone thought more about going to the asteroid belt, that is, the orbit of the planet where the Xuanhuang civilization came to this galaxy for the first time. After the planet was broken, a large number of asteroids were left behind.

But the discovery on Venus forced Dayang Group to change its plan.

Compared with asteroids, Venus is closer and resources are more hit. And Venus itself is huge, and huge factories can be built. There was an active, even heated discussion about this, and the final focus was on one of Venus' biggest problems: the environment.

Zhao Dahe pointed to the picture of Venus and talked eloquently: "The environment of Venus is too harsh, acid rain, high temperature, corrosive atmosphere, strong wind, flash, sand and dust, etc., will cause serious damage to industry and construction, as well as later maintenance and development. Huge bother.

The gravitational pull of Venus is not great, but it is not small either. In such harsh conditions, the cost of launching materials into space will be very expensive. First of all, the laser launch is afraid that it will not work, so rocket launch can only be used. At present, our rocket launch technology is expensive and far exceeds laser launch.

In addition, if you want to develop industries on Venus, you need a lot of water resources. Only concentrated sulfuric acid has been found on Venus for the time being, and the amount is not large, which cannot meet the needs of industrial development at all. Even the resident conditions cannot be met.

To sum up, I think that if you want to develop industries on Venus, you need to draw a question mark for the time being. As far as the current situation is concerned, I think asteroid mining still has more advantages.

As planned, as long as the asteroid is slowed down, the asteroid can fly around the moon by itself.

In contrast, even if the materials in the orbit of Venus are sent to Tianyuanxing, the materials must be accelerated. With our current technology, it is obviously simpler to slow down. Only a little ordinary gunpowder is needed to build a reverse flame cylinder, which is enough to complete the acceleration. "

"But...acceleration is similar. Is there any essential difference between accelerating and decelerating in space?" A small voice came from the end of the conference room.

"Who!" Zhao Dahe stared, "Stand up and speak!"

"Stand up and stand up!" A young man stood up from the end of the conference room, six points similar to Huang Mingshan.

"Oh, Huang Mingshan's son? I remember your name is Huang Bo, right?"

"That's a nickname. My real name is Gold Star!"

Zhao Dahe looked a little unhappy, and the old expert was pushed by the boy: "Okay. The gold star is the gold star. Tell me, which is easier to accelerate or decelerate, and why?"

Jin Xing pouted his neck and said, "It's not which one is easier. From a physical point of view, the principle of kinetic energy is the same no matter whether it is accelerating or decelerating. However, there are still differences when it comes to solving practical problems.

Before I say anything, let me make an assumption first. That is, whether it is asteroid mining or Venus development, the final product must be transported to Tianyuan Planet, right? "

"Yes!" Zhao Dahe nodded.

A confident smile appeared on Golden Star's face: "To transfer materials in space, we must first calculate the orbital velocity.

The orbital speed of Tianyuan star is 30 kilometers per second; the orbital speed is 48 kilometers per second, while the average orbital speed of asteroids is 15 kilometers per second.

Then calculate the potential energy based on the gravitational force of the sun, the gravitational force of the sun at the position of the Tianyuan star is..."

"Okay, I know what you're going to say." Zhao Dahe interrupted Jin Xing, "We've already calculated what you said. If we look at the sun as the basis, the movement of Venus to the Tianyuan star belongs to the Raise the altitude, and the movement of the asteroid to the Tianyuan star belongs to the decrease of the altitude.

In fact, these things do not need to be calculated at a glance. Even from a purely physical point of view, it is still easier to slow down. Not to mention that the materials on Venus must first get rid of the gravity of Venus. "

"But if we develop an asteroid, we need to move the entire asteroid, and the effective resource content of the asteroid is less than 2%; that is to say, 98% is doing useless work.

In contrast, if we build factories on Venus, we can purify the resources and send them back. "

Zhao Dahe stopped talking.

But at this time, another voice came out: "It is too troublesome to build a factory on Venus. If it is only for resources, the resources on Tianyuan Star are very rich and more convenient. The huge Tianyuan Star is enough for us to completely enter the starry sky civilization." !"

Jin Xing glared at him, but this time it was Zhang Xiaoning, the young master of Dayang Group who spoke. Now Zhang Xiaoning's actual age is only six years old, but he has the height of fifteen or sixteen years old, and is even more intelligent. Now he has begun to observe the meeting of Dayang Group.

"Xiao Ning!" Zhang Hao said, "Come to my side."

When Zhang Xiaoning arrived next to Zhang Hao, Zhang Hao knocked on the little guy's forehead, "Don't speak, do you hear me?"

Then Zhang Hao looked at the people who were discussing fiercely, and said: "Your discussions are very meaningful, allowing us to understand space in an all-round way and plan the future of Dayang Group. However, I also have an idea, which gathers all the discussion content of everyone.

I think our plan can be even crazier. "

Crazier?

Everyone looked at Zhang Hao.

Zhang Hao got up, came to the rear wall/display screen, pointed to the galaxy map above and said: "We have discovered three small ice planets in the asteroid belt. The combined volume of these three small ice planets is about the same as One-third of the volume of the moon is equivalent to one-twenty-fifth of the volume of Venus, which is 4% of the volume of Venus.

According to current observations, the water content of these three small planets should be around 60%.

If three icy planets can be landed on Venus, Venus can be moistened, and the water content of Venus can be increased from almost no in the past to about 2.4%.

The water content of Tianyuan Star is only 1.8%! "

Everyone's eyes widened immediately, shocked by Zhang Hao's 'crazier' idea.

Zhao Dahe trembled a little, "Mr. Zhang, this... Even if we can pull the ice planet to the orbit of Venus, the impact force between the planets is enough to completely destroy Venus, and the possibility of disintegration is not ruled out. The worst Possibly, it will lead to changes in the orbit of Venus, or even loss of control.

The collision of such celestial bodies has temporarily exceeded our computing power. "

Zhang Hao smiled: "Who said there is going to be a collision. We are not building a star cannon, just to test the power of the star cannon.

When the three icy planets are close to Venus, we launch an attack from the position of Tianyuanxing, and the shells will fly forty million kilometers or even farther, crushing the icy planets. In this way, Venus can use its own gravity to attract the fragments of the ice planet. In this way, there will be a meteor shower on Venus, a meteor shower with ice cores!

A large amount of ice will reduce the temperature of Venus.

In addition, if the falling angle of the ice rain is calculated, Venus can be rotated through the continuous bombardment of the ice rain. As long as Venus is spinning, its liquid core will generate a magnetic field. Let Venus have the foundation to be a habitable planet.

Then we can build factories on Venus. "

Zhao Dahe, Zhang Xinhan, Huang Mingshan and other scientific research elites of Dayang Group stared at Zhang Hao in astonishment. This plan is really crazy.

But after careful calculation and comprehensive calculation of all the circumstances, the feasibility is even higher!
