After more than a dozen schemes, after half a month of non-stop testing, the power supply problem of the train has never been perfectly solved.

The maximum test speed of Test 1 had already reached 1,800 km/h, but it was only a short dozen seconds, and then the engine went out.

For this reason, Sima Lili has not taken a normal break for many days, and she chooses from different materials every day. So far, all the top materials of human society have been tried.

"Can you help me with this?"

Sima Lili became more and more tired, although she was not impatient, she could also see the loss and helplessness in her heart.

Lin Feng has looked for in the Universe Mall, and the material that is conducive to conduction is nothing more than superconductors at room temperature, but this cannot solve the problem of arcs.

Even if you use high-temperature resistant materials, the arc can not only damage the material at high temperatures, it can even destroy the molecular structure.

That's why he couldn't help it.

But seeing that he was about to succeed in the last step, he was also very unwilling, after all, he had also paid more than 20 days and nights for this. Although most of the time was spent dozing off, at least the time was delayed here.

Time is money.

"Can we think differently?" he finally made up his mind and asked, "for example, not this way of supplying electricity." ”

"What's that for?"

"Is it okay to put batteries on the train?"

Sima Lili stared at him silently for 3 minutes.

I have to say that this is a great proposition, and if it can be used, it will definitely make all of humanity applaud it. But where does the premise come from the kind of battery with huge power storage and small size?

I have time to study this kind of battery, and I have long researched the new material of the trolley line.

But then she thought that Lin Feng had launched a super battery, which claimed to have a stable power supply for 10 years, and the volume was not large.

If this technology is improved, will there be enough super batteries for one train?

Thinking of this, her eyes began to flicker with a touching brilliance.

"Do you really have this technology?"

"Of course," Lin Feng said, and then began to get vaccinated, "but my battery needs to be matched with my engine, and the cost is not cheap." ”

"No matter how much it is, you can bring it to us first. ”

Lin Feng said in his heart that it also costs money to try.

The car he is driving now is equipped with an ultra-concentrated battery and an electric engine, each battery is enough to travel 300,000 kilometers.

This engine and battery are available in high-powered versions in the marketplace, but they are expensive.

A 6,000 kilowatt engine, plus a battery, requires 600 million RMB, and the total cost of an 8-car EMU on the earth is only about 200 million.

Lin Feng turned his hand, and he always had to make some money, right, so the manufacturing cost was higher.

But what Sima Lili sees is not the price, but its use value.

How much power is an armored car, what is the power of a ship, an airplane?

If Lin Feng really has this kind of technology, it will not only change the speed of the train!

In the future, all armored vehicles, and even warships, will not need a lot of fuel and will be able to maneuver over long distances. In the end, she is still responsible for the research of military products, and with any new materials and technologies, she will involuntarily consider this aspect at the first time.

"Buy!" Sima Lili didn't hesitate, "I'll apply for money right away, you'd better start producing now, the sooner the better." ”

Sima Lili left in a hurry, and Lin Feng felt that she was making too much fuss. Isn't it just an engine, even my hands are shaking, and I need to be so excited?

............

Lin Feng took the opportunity to rest at home for a few days, after all, it was a large item, and it was not good to have the goods the next day, although it was not good to have the goods in a few days, but it was finally buffered a little, so as not to be too suspicious.

When he bought the engine and battery, he thought it would be big, but when the goods were delivered to his doorstep, he found that it was only a 1 cubic meter wooden box, and the weight was also very light, so he could pick it up alone.

It was only about 1.5 tons, he estimated the weight, and then found a small truck to help him pull him to the construction site.

Sima Lili was already looking forward to it, and when she saw Lin Feng pulling such a small wooden box, her eyelids couldn't help twitching several times.

"That's it?"

"Of course, hurry up and let the crane come, the master is waiting to go home. ”

Under the strange gaze of everyone, someone pried open the box, and a pure black, square machine appeared in front of everyone.

There was no heat dissipation, no odd shape, just an 80-centimeter-square block made of unknown material, with a shaft about the size of an arm protruding from the center of one side.

In addition, it is equipped with a controller, the size of a palm, which can be wirelessly connected to the engine.

Everyone thinks it's incredible, it's such a thing, and it costs 1.5 billion to buy it from Lin Feng.

"Can you try it?" asked Sima Lili.

"Absolutely. ”

Sima Lili immediately asked people to install the speedometer, and she first had to look at the speed of the engine.

Lin Feng took the controller and set the permissions, and then started to start.

Boom –

The engine made a faint noise, and then he kept picking up speed, and finally the shaft was running very fast.

"Up to 150,000 rpm!" exclaimed the person testing the rpm, "no vibration!

"Install it for me right away!"

With Sima Lili's order, a group of engineers immediately began to act, and she said to Lin Feng again: "If this time is successful, I will help you apply for the position of national scientific adviser." ”

What is the role of a scientific advisor?

Lin Feng doesn't know much about this, so he must be very cheating. I don't look at the president of the United States, there are a lot of advisers and advisers.

"Forget it, where do I have time, this has delayed most of the semester's classes. ”

"You...... What do you do in finance? You're definitely a super genius in physics. ”

Lin Feng replied with a smile: "Of course, it's to make money." ”

Lin Feng didn't believe this answer himself, so far, not much of the money he has earned has been earned by the knowledge he has learned.

After returning to the station to rework some parts, the new engine was finally installed, the commissioning was completed, and it was ready for test runs.

This time, there was no need to think about the problem of the trolley line, so Sima Lili ordered to drive at full speed as soon as she came.

Boom –

The eight-car train sped away with a scream of engines, and in just three seconds, Lin Feng saw the speed on the surveillance screen exceed 600 km/h.

I'll go, this girl's paper is too fierce, and it won't break if he does something.

However, this acceleration obviously satisfied Lin Feng, what is the world's fastest sports car, it takes 3 seconds to accelerate to 100 km/h, and it takes more than 20 seconds to accelerate to 350 km/h.

Now the train just throws them a few streets away.

"Speed 800, everything works!"

"Speed 1400, everything is fine!"

"Speed 1800," the commander-in-chief's voice paused, he should have been a little excited, choked on saliva, "everything is normal!"

"Speed 2000, everything works!"

Everyone in front of the surveillance screen held their breath and their hearts were pounding.

2000 km/h, 130 kilometers from Rongcheng to Fucheng, including acceleration and deceleration time, can be reached in 5 minutes!

"Keep accelerating!" Sima Lili's crisp voice sounded.

"Keep accelerating! 2,500 km/h! Start slowing down now!"

The tunnel came to an end, and the train slowly stopped.

In the ear hole at the end of the tunnel, hundreds of engineers immediately came out and began to carry out the most thorough inspection of all parts of the train.

Ten minutes later, the on-site commander on the opposite side reported by phone: "Everything is normal!"

"Wow!

The people at the scene could no longer suppress their inner excitement, cheering and applauding.

It's an exciting time, with a train traveling at over 2,500 kilometers per hour, enough to refresh anyone's worldview!10
