Lin Feng hadn't observed a tank so closely, and the huge body and gun barrel really made him feel a huge deterrent. Fastest updates

The tank's shell, frame, tracks, wheels, and even screws are supramolecular polymeric materials.

He opened the workshop, and Sima Lili asked the tank to be driven in.

"After half a month of high-intensity testing, we found that the armor and structure, as well as the weight, are impeccable, but we can't solve the heat dissipation problem." ”

Supramolecular polymeric materials are able to insulate themselves from high temperatures, which is what causes this small problem.

"No air conditioning?"

"I installed it, but the effect was not obvious, and the heat emitted by the engine was too great. ”

"Then I really can't help it. ”

Lin Feng shrugged and said, it's not that he doesn't want to help, but he can't help at all. Although there are also materials with good heat dissipation in the universe mall, it is not cost-effective to spend a lot of money to buy special equipment for such a little bit.

"There really can't be helped?"

"Really. Lin Feng nodded firmly.

"Did you know that you're going to miss out on a huge order?"

As soon as Lin Feng heard that there was an order, he was excited: "What order, can you tell me first? ”

Sima Lili laughed: "So you have a way." ”

Well, Lin Feng felt that he had lost to her. The point is that I have been stuffy underground for too long, and my IQ is almost zero, and I don't even see such a simple language trap.

"It's a boat. Sima Lili said, "If you can solve the problem of engine heat dissipation, I can not only help you win orders for armored vehicles, but also a 50,000-ton ship." ”

Of course Lin Feng knew that this was not an ordinary boat, just kidding, 50 yuan a gram!

Even if the frame and shell of a ship are at least 4 percent, that is, 20,000 tons. Multiply the proportion of supramolecular polymeric materials to steel, and it will be at least more than 650 tons.

Random calculation is more than 30 billion, where can ordinary ships afford such materials, it is a waste to use them.

"But I'm afraid my machine can't make anything that big. ”

Lin Feng said with a little regret that the processing equipment for supramolecular polymeric materials is only so large, and the frame for building a tank is just right, so shipbuilding is really not enough.

Unless he buys a large processing machine, but the price is different. If you buy it back and use it a few times, it is estimated that the cost will not be recovered.

"Let's put this issue aside for the time being, let's settle the matter of armored vehicles first. Sima Lili blinked, "I know you can solve the heat dissipation problem, don't worry, the state won't pay you less." ”

Lin Feng thought about it, there were many materials with good thermal conductivity in the Universe Mall, but he felt that heat conduction and heat dissipation alone were not high-tech enough, and if he could make use of these excess energy, he would be tall enough.

"I have a material," he says, "that can quickly convert light and heat energy into electrical energy, with a conversion rate of more than 99 percent." ”

Even with Sima Lili's calmness, she can't be calm at this moment.

If Lin Feng hadn't bragged, then this would be another world-renowned invention!

More than that, it's an invention that can change the world!

At present, the conversion rate of ordinary photovoltaic power generation is only about 15%, and it can only reach 25% in the laboratory.

The energy conversion rate of thermal power plants is less than 50%!

If this material is used in large quantities, one square meter of area can produce 3 kilowatt-hours of electricity a day, and a family only needs a few square meters to use.

Or install this material next to the gas stove, and the heat wasted during cooking will also be converted into electricity!

Sima Lili thought a lot for a moment, but she quickly pulled her thoughts back.

"Okay, when are we going to see this material?"

"Let's go in a few days," Lin Feng really wanted to rest for two days, so he said, "How about I call you then?"

"I don't use my phone," said Sima Lili, "but I'll wait for you here." ”

Leaving the station, Lin Feng breathed a long sigh of relief.

Jia Xiaoliang drove him to the door of the villa in a military jeep, and then began to set up a sentry.

The last time I met a mercenary in Lasa, many people were nervous, so the protection of Lin Feng was already terrifying.

Lin Feng didn't want to care about these things for the time being, he just wanted to take a good bath and then sleep beautifully at night.

As a result, before he got up in the morning, someone rang his doorbell.

Lin Feng looked through the glass of the window, and saw several cars parked outside, and the license plate number was 0 except for the last digit. He thought that Political Commissar Li had said that Mayor Qin had looked for him several times, and it seemed that this was true.

Mayor Qin was received in the spacious living room, and soon someone took out the subway traffic map.

Lin Feng casually glanced at it and found that the 10 lines in the plan had been greatly changed, and the number had also increased to 16.

In this way, the entire underground of Rongcheng is rail transit, and it is convenient to travel. However, the construction of the subway is different from the ordinary railway, there are too many stations, and the construction is still quite difficult.

In this regard, Mayor Qin means that no matter whether it is built now or not, all the tunnels will be opened first.

Lin Feng gave two praises to his decision, the tunnels have been dug out, and all departments should not just watch, those who should be looking for money should find money, and those who should be demolished should be demolished quickly.

Finally, the total mileage is 193 kilometers.

For a small project of less than 2 billion, Lin Feng casually agreed, and he could start construction immediately after the shield machine arrived, and it could be completed in two years.

"In addition, according to the instructions of the provincial party committee, we will also join hands with the Academy of Sciences to build an ultra-high-speed subway pilot in Rongcheng and Fucheng. ”

This proposal Lin Feng is the most supportive, and now the country has developed a train with a speed of 1,000 kilometers per hour, which is almost to the limit on land, and it is possible to go off the rails no matter how fast it is, and the strength of the train itself cannot meet the requirements.

If a train with a speed of more than 2,000 kilometers per hour can be made, it will be a great thing for the whole country and its people. People who are thousands of miles away can even go home for dinner after work and rush back to work the day without being late.

The seafood from the coast was immediately transported to the mainland, so that people could eat fresh seafood.

Even in the future, you don't have to wait for a long vacation, you can go to climb on the weekend, or visit the West Lake.

It's just that this is not a small difficulty, in addition to the tunnels and tracks, the train itself also needs to be improved.

These are not issues that Lin Feng considers, he only needs to be responsible for making holes.

Mayor Qin happily asked people to prepare contracts, helping the department to do things is different from the station, everything must be done in accordance with the requirements of industry and commerce, so taxation is inevitable.

Lin Feng didn't know which company to cooperate with, so he simply finalized it on the spot and set up a construction company, and as for the small problems of qualifications, Mayor Qin came forward to help solve them.

Finally, there is the issue of price, because there is a tax to be paid, so naturally it cannot be the same as the price of the troops, and Lin Feng finally set it at 13 million per kilometer.

Mayor Qin was overjoyed when he heard this, the construction of the subway is no better than ordinary rails, and most of the more than 100 million per kilometer are used for digging tunnels and demolishing them.

Now, with a lot of money saved here, the speed of subway construction can be doubled or even tripled.

This is a great achievement.

After being polite to Lin Feng for a while, Mayor Qin hurriedly took the people away.
