"What should I do when I go to the toilet?" Suddenly, when Mr. Chen was explaining, some parents couldn't help but raise their hands and asked.

"This is simple, this..." Chen Lao said it suddenly stuck, and then looked at several staff members around him and said, "You can explain, what should I do if I go to the toilet?"

"Ah!" The staff was stunned, and after a long time of struggle, he didn't say anything.

"You're here?"

"Old Chen, I don't know."

"Then you come!"

"Old Chen, no one has told me!"

"Wait, you won't have thought about the bathroom issue at all!" the parent couldn't help asking.

"Ahem, this question must have been considered, but everything is still in the R&D stage, so it is very natural to not come up with a unified result!" Chen Lao coughed and said, "And I think the bathroom is actually not a very necessary thing. After all, at the speed of a vacuum high-speed train, it only takes two hours in total from the southernmost end of the border to the northernmost end of the border. In this case, as long as you endure it, it will pass quickly."

"Our train is mainly based on speed, so we naturally have to sacrifice some riding experience!" Mr. Chen explained.

"But this riding experience is too great. The two-hour process must be fixed in this narrow position, with almost no room for movement and you cannot get up. Will you be very tired when maintaining such a posture?" a parent said again.

"No, our chairs have been designed strictly by mechanical engineering, and the chairs can also lie down, making people almost lying flat. How could they feel tired? And two hours are the longest distance. Under normal circumstances, it only takes ten minutes to get from the imperial capital to the demon capital. What are you doing?" Mr. Chen said angrily.

"But why can't we be looser? Why can't we design side by side seats? Many times, family takes the train. At this time, we definitely hope that the whole family can sit side by side and see each other. Instead of being in front and back, we can't even see each other."

"And, if we take care of our children, what if the children need our help? If we cannot come to the children in time, it will be too difficult to feel at ease!" another parent said.

"..." Old Chen opened his mouth, but didn't know how to answer these questions, until Huang He smiled and said, "Grandpas, thank you very much for your opinions. First of all, I want to make it clear that all the things you see are informal products, just test items made to test and explore the most perfect solution!"

"And at present, this prototype car is mainly focused on operation, and pursues the ability to operate freely and safely in the vacuum pipeline. The user experience of passengers has not been fully considered yet. This is just a very rough rough."

"In fact, if you watch the g short video released by our company three years ago, you will find that this has actually changed greatly from the vacuum train envisioned in the CG short video."

"In our vision, vacuum trains are actually a car with three rows of seats, which is about the same width as ordinary subway trains. However, during our research and development, we found that the vacuum pipeline width required by such a width is even more amazing, and the technical content required is also greater."

"If we make changes and reduce the diameter of the originally designed vacuum pipeline by 1/3, the manufacturing cost of the entire vacuum high-speed train will be directly reduced to about 1/10 of the previous one! Then the ticket price of the vacuum high-speed train can be reduced by more than half, and the return time will be greatly advanced."

"Secondly, if the pipeline is reduced, the safety of the pipeline itself will be greatly improved. With the same pipe wall thickness, the compressive resistance of this small vacuum pipeline can reach more than 7 times the compressive resistance of the previously designed large pipelines."

"We have done tests. If a large pipe in the previous period encounters a vehicle collision, it will cause very serious deformation. The worst case is that the pipe leaks directly, which will lead to the collapse of the diagnostic pipe."

"If a vacuum high-speed train happens to pass within its 10-kilometer range, the entire vacuum high-speed train will face the risk of vehicle destruction and death, with the probability of passengers being as high as 2.6%!"

"But if it is the small vacuum pipeline at present, even if it is a direct impact from a heavy loader, it will only cause the pipeline to bend no more than 15 degrees, and will never cause the pipeline to leak and break."

"At the same time, we have also gone through other tests and found that any bullet-like gun cannot cause any damage to the pipeline. Direct impact of howitzers, infantry guns and other weapons may only cause a slight deformation. In fact, we have also tested small air-to-ground missiles, sea-to-ground missiles, and surface-to-ground missiles with weapons."

"All small missiles hit directly can only cause deformation, and may cause damage at a very small probability. If there is no direct hit, it will almost not cause any damage to the entire pipeline."

"If it is a medium- and long-range ballistic missile, if it hits directly, the pipeline will not be able to withstand the damage. But as long as it does not hit the pipeline directly, it will not pose a fatal threat to the pipeline, and the pipeline can still effectively form protection."

"In fact, since the pipe has shrunk by 1/3 of the diameter compared to before, the probability of accurately hitting by enemy guided weapons will also be reduced by more than 80%.

"In addition, we have also tested large natural disasters and found that unless it is a serious earthquake disaster, the land with fixed pipelines has serious displacement, tearing and cracking the pipeline. Or it is encountered with large mudslides, which will impact and bend the pipeline. Except for these two more serious natural disasters, the rest, such as floods and fires, cannot damage the pipeline at all!"

"To sum up, we believe that by reducing the pipeline, more than 90% of safety crisis events can be avoided. The safety probability of vacuum high-speed pipelines will be directly increased from the original 98.32% crisis probability per 100 kilometers in the original ten years to 99.788% crisis probability per 100 kilometers."

"That is to say, if we build a new vacuum highway pipeline of 1 million kilometers, then there will only be 22 life-threatening crisis accidents in 10 years, which is more than three times higher than the current safety of railways."

"This is why we have to make the vacuum high-speed train so narrow that it can only accommodate a human being. It is mainly for safety reasons. Otherwise, everyone would not want to stay worried when riding the vacuum high-speed train!" Huang He smiled.

"Then this is really necessary!" After hearing Huang He's explanation, everyone here was smart, and naturally they understood that Huang He was talking about the hard truth. It is indeed reproachable to sacrifice comfort for safety and economy.

"Of course, the passenger experience must be considered, because this will be the main means of transportation we take in the future!" Huang He smiled and changed the subject, "So we will also make corresponding improvements in the passenger experience functions!"

"First of all, it is a problem with the bathroom. It is really difficult and troublesome to move in a vacuum train, so we plan to further transform the chair in the future and change it into a seat with urination at any time."

"This function is actually very simple. You only need to arrange a catheter under the seat, then place a catheter port on the left, and then gently put it on or paste it. There are already very mature related products in the world, and this is not a problem."

"We just need to place a separate curtain for each seat to isolate the front and rear vision, and that's enough!"

"As for the problem of feces, I'm afraid I can only wait. Because the destinations of high-speed trains are different, the station must transfer the vacuum track in the middle, and this period can provide a certain amount of time to solve the feces. If it really doesn't work, we can ask our crew members for the Diarrhea Pill. This medicine can temporarily relieve the pain in that aspect, but it is not recommended to use it unless it is absolutely necessary."

"..." When parents heard Huang He explain the toilet so sincerely, they couldn't help but feel the atmosphere was a little weird.

"As for the ride experience, we will definitely design the best ergonomic seats to meet long-term sitting. In addition, according to the design, in order to ensure the safety of the human body during the high-speed operation of the train, all seats will actually be folded down to a 45-degree angle with the ground, so that people are almost lying on a chair, and there is almost no difference between sleeping!"

"At the same time, in order to further improve the ride experience, we also plan to install small TVs and video on demand equipment in the vehicle, so that users can lie on a chair and watch TV, further reducing the fatigue and boredom caused by long-distance travel!"

"In fact, we also plan to install Wi-Fi systems in the vacuum pipeline. Because the pipeline is an absolute vacuum environment, the Wi-Fii signal will be extremely good. A Wi-Fi device can cover a range of 10 kilometers, so that users can also experience a good network environment in high-speed trains."

"In short, as a completely new product and transportation tool, vacuum high-speed trains will definitely improve their various abilities and designs in continuous practice. In the future, we also look forward to some excellent designers solving the pain points caused by the current trains for us. Thank you for your support!" Huang He's words instantly triggered a burst of applause from the scene.

Along with the applause, both ends of the vacuum train were completely locked, and a staff member shouted loudly, "The train is ready to be completed, and start entering the start-up procedure!"
Chapter completed!
