Chapter 458: Interstellar Train
readx;
Thank you for the tips of the two brothers Neverend and Blue Sea ♂ Sunny C. Pen, fun, and pavilion www.biquge.info ask for a commuter pass.
Jin San saw that the guy who had just boasted that he had several houses in his hands was always pulling the old lady to climb, and finally after talking for more than ten minutes, he led the old lady upstairs to look at the house.
Hou Zhong smiled bitterly: "This kind of thing happens every day, you see, those people over there are the sales offices of several other houses, and they are selling the houses they just bought from us."
Jin San followed Hou Zhong's fingers and saw that under a few milk trees in the distance, under a sun umbrella, many people in suits and leather shoes were also pointing at them.
Although they were far away, Jin San could still hear their conversation: "That is Jin San?" It's really hairless and can't do things firmly. ”
"If he acts soundly, then there is a way for us to live?"
"That's right, if they weren't too frizzy, how could we have a chance to make money!"
"Big brother, when did the big boss say to start shipping? I think it's about the same time. ”
"That's it, big brother, there are a lot more people who have come to see the house these days, and the willingness to buy a house is very strong."
"Don't worry, boil them up again, the big boss said maybe our price will go up."
"And the price will go up?"
"Of course, many of our houses have been renovated, if the price does not rise, who will pay for it?"
"Because of this price increase? It doesn't scare away customers, does it? You must know that this house is very easy to decorate, and those renovation companies are full of people. It must not be kept secret, and if we increase the price because of this, it is likely to disgust customers. ”
"Put your heart in your stomach, as long as you boil them up a little longer, no matter how much we raise the price, it's okay, the house is a good house, and we're afraid that no one will buy it?
Even if they complain, even if they scold angrily, isn't there still an unlucky Jin family who gives us the bottom? Now we're trying to put the pot on their heads, who let that type of household come late.
If they want to buy a cheap house, they go to the Jin family. If the Jin family doesn't give them a cheap house, shouldn't they scold the Jin family? At that time, they couldn't blame us, could they?"
"That's right, the Jin family has given us a top cylinder, we don't want to make more money, I'm really sorry for those fools."
"When we have a morning meeting tomorrow morning, we should carefully explain to the people below so that they can make it clear to the customer when they meet the guests who come to see the house. The Jin family is the Jin family, and we are us. If you want to buy a cheap house and go to the Jin family, if the Jin family has no ability, it's none of our business. ”
"In this way, the Jin family will be unlucky again."
"Who can be blamed for this? Who made them break the rules? Since we have the courage to challenge the unspoken rules of our entire industry, we must be prepared to take on all kinds of blows. ”
Jin San's face turned blue when he heard this: "Hou Zhong, you hurry up and send me an announcement, we will start selling the house now, on the outskirts of the stables, in a straight line of the Tianmo Golden City, which is ninety kilometers away." Officially released from now.
There are mountains, trees, lakes and lakes, the whole line of houses is 20,000 square meters, and the suspension train from the Golden City to the stable is one train per minute, and it takes 12 minutes to go back and forth. Immediately, go make a copy at once, and I'm going to let everyone in the whole stable know about it tonight. ”
"Heavenly Desert Golden City? Suspension trains? A round trip to the stable only takes 12 minutes? Boss, can we really do this?" Hou Zhong looked at Jin San, whose face was pale. I was afraid that he would be confused, so I hurriedly said.
"Yes, there is no room for us to show our skills in the stable, the original Tianmu base is just suitable for real estate development, if the desert of more than ten square kilometers can be developed, I see how those people will die."
"Boss, that's a straight-line distance of ninety kilometers, can we really make people go back and forth once in twelve minutes?" Hou Zhongdao.
Jin San is not at all worried about this, he has already asked Jin Lan to make a suspension train, originally he planned to open the air passage from the three towns of Wangquan to the Devil City, of course, now it is nothing to open the communication line between the sky and the stable.
"Jin Lan should have a suspension train in his hand, the fastest speed of the suspension train can reach three times the speed of sound, a speed of one kilometer per second, and ninety kilometers only takes ninety seconds.
Coupled with the buffer time of train acceleration and deceleration, it is absolutely feasible to fly once in six minutes, so that the time for a round trip is only twelve minutes, as long as we have twelve of this kind of trains, then there is a suspension train every minute to go back and forth between the stable and the desert, it is no longer a problem, and this distance is no longer the weakness of the desert development case. ”
"Also, I thought about it just now, since the place in the desert is not small, let's give a little more discount, the houses there are divided into several prices, the highest price is 30,000 square meters, this is a luxury area, such a place to build a villa.
The price of 11,000 square meters will be built into a small courtyard, 5,001 square meters will be built into a low-rise residential house, and 3,010 square meters will be built into a high-rise. Jin San said viciously while planning.
"Ahh Only then did Hou Zhong really be shocked, he had long known that his boss was ruthless, but he didn't expect to be so ruthless, this is not to give the zinc real estate developer a way to live!
"Also, you remember, in addition to the large levitation train, the small maglev speed, we also have to mass produce a part, such a flying car is not a threat to us at all, and after it is produced, it will be sold to domestic tycoons, so as to promote our development project more.
The global village is like this, with a flying car, where to live or not to live? But the price should be more expensive, otherwise who will we sell our house to? With flying cars, people can live wherever they want, if this is the case, our Tianmo Golden City will not have any advantages at all.
If this happens, then we can still get some more money, so that our other plans will be implemented more smoothly. ”
"Boss is going to expose some technology this time?" Hou Zhong couldn't help but say.
Jin Sandao: "It's nothing if the magnetic levitation technology is exposed, after all, we have better anti-gravity technology." Besides, magnetic levitation technology has been developed to a very high level in various countries, so we don't need to hide it. ”
Hou Zhongdao: "Recently, I have also seen some research in this area, and Israel has also developed a maglev train with good performance, so it seems that even if we launch a maglev train with a higher level of technology, it will be nothing."
The maglev flying car produced in Israel does not have wheels, and the "inverted U-shaped" opening electromagnet under the vehicle replaces the wheels, and as long as the electromagnet is supplied with electricity, the train can be suspended in the air and walk forward under the action of electromagnetic force.
The train runs suspended 8 mm above the line. The maximum speed can reach 110 kilometers per hour, which is neither fast nor slow, but it is faster than ordinary trains, but its construction cost is much higher.
The noise in the carriage of the maglev train is about 65 decibels, which is lower than the noise of about 75 decibels in the general subway."
Although the body will feel a slight shaking when the train is driving to a curved line and speeding up, the shaking sensation is not strong.
The first to use maglev trains was Japan, and later there was a real power except for one South Korea. But the maglev running route was not really built.
The Korean maglev train line is after Nagoya, Japan. The world's second urban maglev train to achieve successful practical operation, and now there is another Israel, which makes maglev technology begin to go to the people, so Jinsan's release of maglev technology is not too outstanding.
And the reason why Jin San released trackless maglev technology is because of a plan of the Americans, although they have not developed a maglev route, they want to open up a space route.
This is the U.S. Startrain program, which uses a 1,000-mile-long Startrain launch system. About 1,609 kilometers, a pipeline and a superconducting cable send the maglev train to low-earth orbit.
The launch system, known as the "interstellar train", uses a vacuum tube about 1,609 kilometers long and a superconducting cable to send the maglev train to low-Earth orbit.
This technology is not only achievable, but also much less expensive to implement than the cost of a rocket.
Although the "Star Train" system may sound a little incredible, its basic concept is very simple.
Because the maglev train is suspended on the track, there is no need to worry about friction.
Theoretically. They are much faster than the existing speed of about 563 kilometers per hour and can reach orbital speeds of 3,219 kilometers per hour.
Of course, in order for passengers to be able to accelerate to this speed safely, the "interstellar train" system requires a large number of tracks. At the same time, it is necessary to prevent the hypersonic train from being torn to shreds by the surrounding air.
Maybe it will take another ten or twenty years for the Americans to do this, but Jin San can easily do it now, so Jin San will peek into this plan of the Americans.
According to the intelligence analysis obtained by Kim San, the 1,609-kilometer-long pipeline should be able to complete this task by simulating the low pressure in the middle layer.
Most of the pipeline will be flush with sea level, and the exit point will need to be about 19.3 kilometers above sea level, which is used for magnetic levitation technology in the train, which can also be used to levitate the pipeline.
In the launch pipe, a superconducting cable with 20 million amperes at an altitude of 20 kilometers generates a levitating force of about 4 tons per square meter, which is enough for an interstellar train.
The excess buoyancy required to address the vacuum tube itself through high-strength cables, such as the strength of Dyneema's super-strong fibers, is sufficient for this purpose.
There is also a back-up system to ensure that the suspension system runs smoothly without failure.
This may sound unrealistic, but the engineering required to support a 19.3-kilometer cable is much simpler than the engineering required to support a much longer space elevator.
U.S. engineers intend to build such systems in polar regions such as Alaska, northern Canada, Greenland or Siberia, and the Antarctic ice sheet is an alternative site.
Their research team estimates that it could take 20 years and $60 billion to build a manned "interstellar train" system.
These numbers sound great, but when you consider the various costs of the Space Shuttle, which is three times the cost of the Startrain system, you would think that the system is really economical.
Moreover, once the Startrain system is built, it will cost only $50 per kilogram to deliver goods to LEO, compared to $10,000 per kilogram and $100,000 per kilogram of weight for goods and people on LEO with current technology.
This means that a ticket for space travel costs only about $5,000, and the designers estimate that the "interstellar train" system has an accident rate similar to that of modern airliners, with a high safety factor.
Another advantage of the Startrain system is its ability to quickly send tons of material into orbit, which can be used to effectively defend against any large celestial body crashing into our Earth.
Researchers also see this function as the most important application of the "interstellar train" system, and at present, humans on Earth do not have the ability to defend against asteroid or comet impacts, or even the ability to issue impact warnings in advance.
In order to be able to truly defend against celestial impacts, humanity needs more powerful warning systems, as well as multiple large, high-speed interception systems that can be pre-installed in orbit to monitor and defend against possible threats at any time.
This requires the launch of multi-ton equipment into orbit, which is unrealistic for current high-cost launch systems.
And Jin San cares about this, because he also has ambitions to develop outer space, of course, Jin San has this ambition, and there is no way to do it.
The biggest crisis facing Jin San now is not that someone is asking him for trouble, nor that he has no technology, but that he does not have enough resources to build more warships.
As for the threat of the enemy, Jin San has never been too afraid, as long as he continues to grow stronger, he is not afraid of even if there are many enemies.
What's more, until now, Jin San has not found an enemy that is enough to threaten his survival, not even those aliens.
As far as the alien technology he knows, it is only in the initial stage of entering space, just like the Helicarrier he captured, which is already the pinnacle of alien technology, but this technology is not much higher than the earth technology.
The most important thing is that as landlords, alien warships do not have much advantage in fighting against the native forces of the earth, and their weakness is that the battle line is too long and there is not enough rear support, and their technological advantage cannot bring them victory.
And this is the biggest weakness of their warships, the speed of the battleship is too slow, it takes two or three years to come to Earth from Mars, if the aliens do not find a stable logistics base around the earth, and the speed of the battleship back to the home planet is so slow, then, the aliens will have no advantage in the face of the forces of the earth.
