In the internal conference room of the headquarters of General Motors of the United States, it was unusually quiet, all the senior executives of the company were in place, up to the president of the company, down to the CEO of every region, all the bosses did not speak, and the rest of the people naturally did not dare to speak, everyone sat like this, and the atmosphere seemed very solemn, "Everyone, although I don't want to hold anyone responsible, but can you give me an explanation" After a while, the boss finally spoke, his tone was very flat, but everyone was behind this blandness, and everyone heard the anger and everyone used their brains, Moved his mind, secretly guessed the meaning of the boss's words, this meeting seemed very abrupt, the company did not run through the spirit of the meeting in advance, so, everyone is confused "Can anyone tell me, what do those people in the R&D department do It took so many years to eat, how much R&D funds were spent, but what was the result" The more the boss spoke, the more stern he became, his eyes looked at the R&D manager like a knife: "Mr.
Michael, can you tell me how far the company's research on maglev vehicles has progressed" The original crux of the problem is that Michael, the manager of the R&D department, is a white middle-aged man, with blonde hair, a tall body, and a handsome face, but at this moment, under the gaze of the boss, like sitting on pins and needles, Junlang's face is full of helplessness and wrong."
Mr.
Michael, didn't you hear me," the boss shouted again."
Boss, we have not made a major breakthrough in the research of maglev vehicles for the time being, and we have been troubled by the special track project" In the face of the boss's questioning, Michael had to answer hard.The boss of the "special track" sneered: "Could it be that the company has spent a huge amount of money and raised a group of pigs, why haven't you thought about developing new magnetic materials?"
"But boss, other companies in the world are tackling specific tracks, and few people are thankless to develop new magnetic materials" Michael was slanderous in his heart, but he didn't dare to confront the boss in front of so many people, so he could only say so.Other people also feel aggrieved for Michael, the company spent a lot of money on the maglev car to deceive the ghost, for the boss's words, many people scoffed at why, because whether it is GM, or other automobile giants in the world, did not pay too much attention to the research and development of maglev vehicles, did it cost money on this, did it invest, but the research funds are much less than other research and development projects, which has to start from the development process of magnetic levitation technology, maglev technology is a high-tech invention of the Germans.In 1922, the German Hermann Kemper proposed the idea of electromagnetic levitation.In 1934, the German company Siemens and ThyssenKrupp had the world's leading technology for the design and construction of maglev trains, and Germany built a 31 road in the small town of Emsland in the northwest in 1987.5 km of experimental routes.After more than 10 years of trial operation, the "maglev" train has proved its technical reliability, but it has not proved commercially feasible, and although many parts of Germany want to start the project, it has not been approved until now.Expensive construction costs and expected losses led to the maglev project never being launched in Germany.In 1997, Germany planned to build a maglev line from Berlin to Hamburg, with a total length of 292 kilometers, which can be reached from Berlin to Hamburg in an hour.According to expert calculations, even the most optimistic estimates of the number of passengers on the maglev train between Berlin and Hamburg will lose 100 million marks per year after the maglev train is put into operation.Read moreAt the beginning of 2000, the project was officially discontinued in a quarrel because no one was willing to increase investment, let alone pay for future losses.Another reason for the blockade of maglev is public opposition, with 58 percent of the German public in a poll believing that the maglev project is too ahead of its time for the German economy, while 39 percent of respondents believe that maglev is "unnecessary" and too expensive.While the magnetic levitation technology has suffered one blow after another in Germany, Germany has stepped up its international marketing efforts.According to reports, Amsterdam in the Netherlands, Budapest in Hungary, individual cities in the Czech Republic, and Las Vegas in the United States have all moved the idea of building a maglev train line under the lobbying of the Germans.However, these ideas were ultimately shelved because of cost.What is amazing is that just when the maglev technology maglev project was about to be stillborn, Huaxia appeared as a savior.The world's first and currently the world's only commercially operated maglev train line was built in Shanghai, China, which was jointly developed by China and Germany, with a total length of about 30 kilometers, connecting Shanghai with Pudong International Airport.It was first opened to traffic on December 31, 2002.In April 2006, it passed the national comprehensive acceptance and is now officially operational.After the completion of the Shanghai maglev train, German TV stations broadcast the news one after another, although some people sighed, some people were disappointed and jealous, but more people were very sensible: "There is no way, because we Germany do not have too much money to work on such a big project".With the operation of the Shanghai train, the Germans gained a kind of psychological comfort, because the Shanghai maglev project had indeed incurred huge losses.The Germans must have been proud of their consistent opposition, and of course secretly congratulated themselves on the "weakness and incompetence" of their own government and the "inefficiency of decision-making".Kind-hearted people can't help but ask, knowing that it is a loss to make money, why does Shanghai want to build a maglev train that no one in other countries cares about and avoids, I am afraid that it can only be attributed to our characteristic system, the lovers of this system have always been proud that we can concentrate on doing great things, without the people's participation in the demonstration, not to mention the people's authorization and consent, and not afraid of the people's opposition, as long as our leaders pat their butts, everything will be done.Even if you do something stupid, you will only spend money to pay the tuition, and no one will be responsible for it, let alone be held accountable for it.The reason why maglev trains could not be developed is obvious: high cost, low efficiency, and unpopularity, which these Germans have long foreseen.Since the "stop" of the maglev project in Munich, Germany, the topic of maglev trains has completely disappeared in Germany.Only in Shanghai, China, this high-speed train continues to run between the city and the airport, although the speed of the train reaches 430 kilometers per hour, claimed to be second only to the speed of airplanes, but because of the small number of passengers, it has been running at a loss, and now it can only be reduced to a tourist equipment.A tourist said: "If you come to Shanghai, taking the maglev train and going to the TV tower is an indispensable project" It is estimated that the passenger load of the train is significantly less than 50, and the annual loss is more than 30 million euros, according to the data, the financial loss of Shanghai maglev company from 2004 to 2007 exceeded 1 billion yuan.At present, the maglev attendance rate is only 1\6, half of which are business delegations and tourists, and the utilization rate is extremely low, which seriously affects profits.In fact, Shanghainese have never fully embraced maglev trains, and one of the reasons is that the location of the line is not in the center of the city west of the Huangpu River, but in the suburbs of Pudong, which is inconvenient.In addition, the 50 RMB ticket price is a bit too expensive.A Shanghai citizen said: "I have never taken a maglev train, because there is no need for this, the people who take the maglev are tourists, and people usually take the subway to the airport, the price is cheap, and if the time is tight, they simply take a taxi." ”Now, no one talks about the extension of the line, and the operators and German technology companies involved in the construction, Siemens and thyssenkrupp, had planned to extend the maglev track from Shanghai to Beijing, or at least to Hangzhou, 170 kilometers from Shanghai.Now that the plan has been cancelled, Shanghai's residents are strongly opposed to the expansion project, comparing the maglev train to an "urban toy", and many experts and scholars have even written articles against the project.They believe that the maglev technology is not compatible with China's existing wheel-rail technology, and the construction cost is more than twice as high as the wheel-rail technology, while the operating cost is several times higher, and the transportation capacity is low, especially the flexibility of the volume is poor, and the adaptability of the morning and evening peaks is poor.In terms of safety, I am especially worried that the maglev train has no wheels, and if there is a sudden power failure, it is easy to cause accidents by sliding friction.Of course, the opposition to maglev in various countries is also due to environmental considerations.So far, Germany has not been able to come up with strong evidence that a strong magnetic field is harmless to the human body.Therefore, Germany has made a rule that no one is allowed to live on both sides of the maglev line for 500 meters, and there is no shortage of sober people in China, who have expressed deep concern about the harm of maglev.Some experts have said that it takes several generations for nuclear magnetic emission pollution to manifest itself, and the harm caused to the human body has a cumulative effect, which can genetically change various human functions, so that people suffer from some strange and difficult to treat diseases.For radiation, the electromagnetic radiation of medium and low-speed maglev is harmful to the human body, and the long-term effect will cause a variety of diseases.In the face of controversy, some experts have proposed to let the maglev train go underground, which was immediately refuted, technical analysts pointed out that the maglev into the ground, the air pressure in front of the carriage is greater, the resistance is also large, and the speed advantage is difficult to reflect.At the same time, the amount of wind used to dissipate heat will be reduced, and the heating of the coil will easily cause accidents.Although this technology has been neglected, the statement of a person in charge of the Shanghai Maglev Technology Research Center is still very intriguing brothers, ask for support:
