Returning to the ground, Zhang Hao quickly convened a high-level meeting of Dayang Group. The problem of selling the small spacecraft left by the Xuanhuang civilization discovered on the moon base was solved in a few words.
In fact, everyone has already had this idea about selling spaceships.
With the recent development of space, financial pressure has been extremely great, and it is time to open source. Especially since everyone now has cooperation and competition, holding good things in your hands and not letting them go will not be good for the long term.
However, we have never been able to reach a consensus on when to sell it and what the price will be. However, the general conditions are already in place.
With this opportunity now, everyone quickly finalized the transaction plan: the spaceship is sold for 8.5 billion spiritual yuan, 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 price for one first
Say it again.
The price of the spaceship is 8.5 billion spiritual stones, which sounds a bit high, but the actual situation is not high - after all, this is a legacy of advanced civilization, and the smallest spacecraft is more than 100 meters in diameter and has powerful transportation capabilities. At present,
When space development has just started, this kind of transportation capability is extremely valuable.
Before this, everyone’s transportation costs in space were calculated in terms of grams. For example, the cost of materials launched from the ground to space by the Ocean Group was as high as 4 yuan per gram - the purchasing power of the currency of the Ocean Group is not small.
One yuan can buy five kilograms of brown rice, which is equivalent to three days of rations for an average family.
The transportation cost from Tianyuan Star orbit to the moon would be as high as 2 yuan/gram if transported by rocket. Thinking about industrial construction, it is often calculated in millions of tons, and the transportation cost of 2 yuan/gram is unbearable.
After the spacecraft is launched, the transportation cost between spaces will drop significantly, to as low as a thousand yuan per ton - mainly due to the high cost of nuclear fuel for the spacecraft and the high cost of maintenance of the spacecraft.
In short, as space technology becomes more and more perfect, and Xuanhuang Group and Hetu World are also planning to make a difference in space, it is imperative to purchase a spacecraft from Dayang Group.
Fortunately, Dayang Group has already considered this point, and Zhang Hao also knows very well: the current situation on Tianyuan Star is different from the earth in the past.
In the past world, no extraterrestrial threats were found, so all parties fought hard and tried to hide good things, fearing that their neighbors would find out.
But this world is different. We are facing powerful threats. Under this threat, we have to try every means to develop and become stronger. Cooperation with each other is inevitable; or it is the only choice.
But cooperation is cooperation, and brothers have to settle accounts clearly.
After deciding on the spaceship, everyone immediately moved on to the next meeting: Venus development!
Discovering a large amount of high-grade ores on Venus is something that has never been thought of before. Previously, everyone considered more about going to the asteroid belt, which is where the Xuanhuang civilization first settled in this galaxy.
After the orbit and the planet were 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 has more resources. Moreover, Venus itself is huge and can build huge factories. Everyone started active and even heated discussions on this, and the final focus was on the biggest problem of Venus.
: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 winds, violent flashes, sand dust, etc. will cause problems to industry and construction, as well as later maintenance and development.
Huge trouble.
Although the gravity of Venus is not large, it is not small either. Under such harsh conditions, the cost of launching materials into space will be very expensive. First of all, laser emission is probably not possible, and the only option is rocket launch. And currently our rocket launch
The technology is expensive and far more expensive than laser emission.
In addition, if you want to develop industry on Venus, you need a lot of water resources. What has been temporarily discovered on Venus is only concentrated sulfuric acid, and the quantity is not large, which cannot meet the needs of industrial development. It cannot even meet the conditions for permanent personnel.
To sum up, 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 still has more advantages.
Just 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 Tianyuan Star, the materials still need to be accelerated. With our current technology, deceleration is obviously simpler. It only requires a little ordinary gunpowder to build a reverse flame tube.
, is enough to complete the acceleration.”
"But...acceleration is about the same. Is there an 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, stand up!" A young man stood up from the end of the conference room, who was very 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. The old expert was actually contradicted by the young boy: "Okay. Gold star is gold star. Tell me, acceleration or deceleration, which one is easier and why?"
Student Huang Xing frowned and said: "It's not which one is easier. From a physical point of view, the principle of kinetic energy is the same regardless of acceleration or deceleration. But if we put the matter into solving practical problems, there are still differences.
Before I say anything, I first have to make an assumption. That is, whether it is asteroid mining or Venus development, the final product must be transported to Tianyuan Star, right?"
"Yes!" Zhao Dahe nodded.
A confident smile appeared on Huang Xing's face: "To transfer materials in space, you must first calculate the orbital speed.
The orbital speed of Tianyuan Star is 30 kilometers per second; the orbital speed is 48 kilometers per second, and the average orbital speed of asteroids is 15 kilometers per second.
Then calculate the potential energy based on the gravity of the sun. The gravity of the sun at the location of Tianyuan Star is..."
"Okay, I know what you are going to say." Zhao Dahe interrupted Jin Xing, "We have also calculated what you said. If we look at the sun as the basis, the movement of Venus to Tianyuan Star belongs to
The altitude is increased, while the movement of the asteroid towards Tianyuan Star is a decrease in altitude.
In fact, these things don’t need to be calculated, they are clear at a glance. Even if calculated from a purely physical perspective, it is still easier to slow down. Not to mention that 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 to say, 98% is 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 is too troublesome to build a factory on Venus. If it is just for resources, the resources on Tianyuan Star are abundant and more convenient. The huge Tianyuan Star is enough for us to fully enter the starry sky civilization
!”
Huang Jinxing glared at the other party. The person who spoke this time turned out to be the young master of Dayang Group, Zhang Xiaoning. Zhang Xiaoning, who is only six years old now, is already fifteen or sixteen years old and very smart. Now he has begun to observe the meetings of Dayang Group.
.
"Xiao Ning!" Zhang Hao said, "Come to me."
When Zhang Xiaoning arrived next to Zhang Hao, Zhang Hao knocked the little guy on the forehead, "You are not allowed to talk, do you hear me?"
Then Zhang Hao looked at the people who were having a heated discussion and spoke: "Your discussions are very meaningful, allowing us to fully understand space and plan the future of Dayang Group. But I also have an idea that brings together all the discussions.
I think our plan can be even crazier."
More crazy?
Everyone looked at Zhang Hao.
Zhang Hao stood up, came to the rear wall/display screen, pointed to the galaxy map above and said: "We have currently discovered three small ice planets in the asteroid belt. The combined volume of these three small ice planets is approximately equivalent to
One-third of the volume of the moon is equivalent to approximately one-twenty-fifth of the volume of Venus. That 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 ice planets can be landed on Venus, Venus can be moistened, and the water content of Venus can be increased from almost none in the past to about 2.4%.
Zhao Dahe trembled a little, "Mr. Zhang, this...even if we can pull the ice planet into the orbit of Venus, the impact force between the planets is enough to completely destroy Venus, and even the possibility of disintegration is not ruled out. The worst case scenario
It may lead to changes in the orbit of Venus and even loss of control.
This kind of collision of celestial bodies has temporarily exceeded our calculation capabilities."
Zhang Hao smiled: "Who said there was going to be a collision? We are building the starry sky cannon, just to test the power of the starry sky cannon.
When the three ice planets are close to Venus, we launch an attack from Tianyuan Star. The cannonballs will fly 40 million kilometers or even further, shattering the ice planets. In this way, Venus can use its own gravity to crush the ice planets.
The debris is attracted. Then there will be a meteor shower on Venus, a meteor shower with ice cores!
Large amounts of ice would lower the temperature of Venus.
In addition, if the falling angle of the ice rain is calculated, Venus will be able to rotate through the continuous bombardment of the ice rain. As long as Venus rotates, its liquid core will generate a magnetic field, giving Venus the foundation to become a habitable planet.
Then we can build factories on Venus."
Zhao Dahe, Zhang Xinhan, Huang Mingshan and other scientific research elites from Dayang Group looked at Zhang Hao in stunned silence. This plan is really crazy.
But carefully, after considering all the circumstances, the feasibility is actually higher!
