Back on the ground, Zhang Hao quickly convened a high-level meeting of the Ocean Group. The problem of selling small spaceships found on the moon base and left by the Xuanhuang civilization was solved in a few words.
In fact, the sale of spaceships, people already have this idea.
With the recent development of space and great pressure on funds, it is time to'open source'. Especially if everyone has cooperation and competition now, holding good things in their hands and not letting them go is not good for long-term.
However, when it was sold and what the price was, I had not been able to reach a consensus; but the general conditions were already there.
Now at this opportunity, everyone quickly finalizes the transaction plan: the spaceship sells for 8.5 billion yuan, and it 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 one in full. Say again.
The spaceship costs 8.5 billion spirit stones, which sounds a bit high, but the actual situation is not high-after all, this is left by advanced civilizations, and the smallest spaceship also has a diameter of more than 100 meters, with strong transportation capabilities, in the current With the space development just started, this transportation capacity is extremely precious.
Prior to this, everyone's transportation costs in space were calculated in gram. For example, the cost of materials launched by the Ocean Group from the ground into space is as high as 4 yuan per gram. The currency purchasing power of the Ocean Group is not small. One yuan can buy five pounds of brown rice, which is equivalent to three days of food for ordinary families.
The transportation cost from the orbit of Uranus to the moon, if transported by rocket, is also as high as 2 yuan. When thinking about industrial construction, it is easy to calculate in terms of millions of tons, and the transportation cost of 2 yuan is unbearable.
After the spacecraft is enabled, the transportation costs between space will be greatly reduced, which can be reduced to thousands of yuan per ton-mainly due to the high cost of nuclear fuel for the spacecraft and the high maintenance cost of the spacecraft.
In short, as space technology becomes more and more perfect, and as Xuanhuang Group and Hetu World also plan to make a difference in space, it is imperative to buy spaceships from Ocean Group.
Fortunately, the Ocean Group has already considered this point, and Zhang Hao is also very clear: the situation of Tianyuanxing is different from that of the earth.
In the past world, no alien threats were found, so all parties were vigorously pulling their backs and pulling their hind legs, and there were good things tucked away, afraid that their neighbors would know.
But this world is different, and everyone faces a powerful threat. Under this threat, everyone has to do everything possible to develop and become stronger. Mutual cooperation is inevitable; or it is the only option.
But cooperation is cooperation, and brothers and sisters have to settle their accounts.
To finalize the spaceship, everyone will immediately proceed to the next meeting: Venus Development!
A large amount of high-grade ore was discovered on Venus, which was not thought of before. Earlier, everyone thought more about going to the asteroid belt, where Xuanhuang civilization came to the orbit where the galaxy first resided. After the planet shattered, a large number of asteroids were left.
But the discovery on Venus forced the Ocean Group to change its plan.
Compared to asteroids, Venus is closer and resources are more hit. And Venus itself is huge and can build huge factories. Everyone had active and even intense discussions on this. The final focus was on Venus’ biggest problem: the environment.
Zhao Dahe pointed at the picture of Venus and talked eloquently: "The environment of Venus is too bad, acid rain, high temperature, corrosive atmosphere, gusty wind, flash, sand, etc., will cause industry and construction, and later maintenance and development, etc. Great distress.
Although the gravity of Venus is not large, it is not small. Under such harsh conditions, launching materials into space will be very expensive. First of all, the laser launch is probably not going to work, and can only be launched with a rocket. At present, our rocket launch technology is expensive and far exceeds laser launch.
In addition, the development of industry on Venus requires a lot of water resources. What was temporarily discovered on Venus was only concentrated sulfuric acid, and the amount was not large, which simply could not meet the needs of industrial development. Even the conditions of permanent residency cannot be met.
In summary, I think that if you want to develop industry 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 is still more advantageous.
As planned, as long as the asteroid is decelerated, the asteroid itself can fly around the moon.
In contrast, even if the material in Venus' orbit is sent to Tian Yuanxing, it will be accelerated. With our current technology, deceleration is obviously easier. It only takes a little ordinary gunpowder to build a reverse flame tube, which is enough to complete the acceleration. "
"But... acceleration is similar. Is there an essential difference between acceleration and deceleration in space?" A small voice came from the end of the conference room.
"Who!" Zhao Dahe glared, "Stand up and talk!"
"Stand up, stand up!" A young man stood up from the end of the conference room, similar to Huang Mingshan in six points.
"Oh, Huang Mingshan's son? I remember you called Huang Bo, right?"
"That's a nickname. My name is Golden Star!"
Zhao Dahe looked a little unhappy, and the old expert was even topped by the Maotou kid: "Okay. The golden star is the golden star. You tell me, acceleration and deceleration, which is easier, why?"
Jin Xing shook his neck and said, "It is not easier. From a physical point of view, the principle of kinetic energy is the same regardless of acceleration or deceleration. However, if you put things in the solution of actual problems, there are differences.
Before talking about it, let me make a hypothesis. That is, whether it is asteroid mining or Venus development, the final product must be shipped to Tianyuanxing, right? "
"Yes!" Zhao Dahe nodded.
A confident smile appeared on the face of Golden Star: "To transfer materials in space, first calculate the orbital speed.
The orbital speed of Uranus is 30 kilometers per second; the orbital speed is 48 kilometers per second, while the orbital speed of an asteroid is 15 kilometers per second on average.
Then calculate the potential energy according to the gravity of the sun. The solar gravity of the position of the celestial star is..."
"Okay, I know what you are going to say." Zhao Dahe interrupted the words of the golden star. "You said that, we have also calculated it. If you look at the sun as the basis, the movement of Venus to the Uranus belongs to Increasing the altitude, and the movement of the asteroid to the celestial planet, belongs to decreasing the altitude.
These things don't need to be calculated, they are clear at a glance. Even from a purely physical point of view, it is easier to slow down. Not to mention the materials on Venus must first get rid of Venus' gravity. "
"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, 98% is doing useless work.
In contrast, if we build a factory on Venus, we can purify the resources and send them back. "
Zhao Dahe stopped talking.
But at this time, another voice came out: "It's too much trouble to build a factory on Venus. If it is just for resources, the resources on Tianyuanxing are very rich and more convenient. The huge Tianyuanxing is enough for us to fully enter the starry civilization. !"
Golden Star glared at each other. This time it was the young master and Zhang Xiaoning of Dayang Group who spoke. Zhang Xiaoning, whose actual age is only six years old, is already fifteen or sixteen years old, and he is even more intelligent. Now we have started to listen to the meeting of the Ocean Group.
"Xiaoning!" Zhang Hao said, "Come beside me."
When Zhang Xiaoning arrived next to Zhang Hao, Zhang Hao knocked on the head of the little guy, "No speaking, no hearing."
Then Zhang Hao looked at the heated discussion and said: "All of your discussions are meaningful, allowing us to fully understand the space and plan the future of the Ocean Group. But I also have an idea that brings together all the discussions.
I think our plan can be even crazier. "
Crazier?
Everyone looked at Zhang Hao.
Zhang Hao got up and came to the rear wall display, pointing to the galaxy diagram above: "We have found three small ice planets in the asteroid belt. The three small ice planets add up to the size of the moon. One-third of the volume of Venus is approximately one-twentieth of the volume of Venus. That is 4% of the volume of Venus.
The water content of these three small planets, according to current observations, should be around 60%.
If three ice planets can be landed on Venus, Venus can be humidified, and Venus’ water content can be increased to 2.4% from almost nothing in the past.
The water content of Uranus is only 1.8%! "
Everyone suddenly glared wide, and was shocked by Zhang Hao's "crazy" idea.
Zhao Dahe was a little trembling, "Mr. Zhang, this... Even if we can pull the ice planet to Venus orbit, the impact force between the planets is enough to cause complete destruction of Venus, and even the possibility of disintegration is not ruled out. Possibly, it will cause Venus to change its orbit, or even get out of control.
This collision of celestial bodies has temporarily exceeded our computing power. "
Zhang Hao smiled: "Who said it was about to collide. We are not building a starry sky cannon, just check the power of the starry sky cannon.
When the three ice planets approached Venus, we launched an attack from the position of Uranus. The shells would leap 40 million kilometers or even further, crushing the ice planet. In this way, Venus can use its own gravity to attract the debris of the ice planet. In this way, there will be a meteor shower, a meteor shower with ice core!
A lot of ice will reduce the temperature of Venus.
In addition, if the angle of ice rain is calculated, it will be possible to rotate Venus through the continuous bombardment of ice rain. As long as Venus rotates, its liquid core will generate a magnetic field. Let Venus have the foundation to become a livable planet.
Then we can build a factory on Venus. "
The scientific elites of Dayang Group, such as Zhao Dahe, Zhang Xinhan, Huang Mingshan, stared at Zhang Hao in dumbfounded. This plan is crazy enough.
But carefully and comprehensively calculate all the circumstances, the feasibility is even higher!
