Chapter 39 Professor Wang Shan's Admiration

"Hello, what do you think of the invention of the coin-operated electromagnetic rifle?"

Reporter Chen Hang, who was sitting opposite Professor Wang Shan, asked his question.

Professor Wang Shan, who was being interviewed, replied with emotion:
"A coin-type electromagnetic rifle. I studied it a little bit. To be honest, I was really surprised. I didn't expect that there would be such an excellent person among the people."

"Oh? Why do you say that? Isn't this coin-operated electromagnetic rifle just a simple toy?"

Chen Hang continued to ask his questions.

“Outsiders see the excitement, insiders see the details, the technology involved is not as simple as imagined.

Because Lin Feng did something impossible and successfully increased the theoretical effective attack distance from 12 meters to 15 meters, increasing the effective attack distance by 3 meters! "

"The theoretical effective attack range is only 12 meters? Shouldn't it be 15 meters?"

Chen Hang showed a surprised expression.

"That's right, under normal circumstances, the theoretical effective attack distance is only 12 meters, not 15 meters.

Because after I got the information you provided, I calculated how much effort it would take to make a similar electromagnetic rifle and whether it could be further improved.

As a result, I found that relying on the existing battery and material technology of mankind, it is difficult to increase the effective attack distance of coin bullets to 15 meters without targeted design of the coil.

Because according to the existing material technology of mankind, without targeted design of the coil, a single coil can only exert a maximum of 2.2 to 2.6 joules of kinetic energy on the coin.

Based on the maximum kinetic energy of 2.6 joules, the total distance of the 11 coils is only 12 meters.

But the coin-type electromagnetic rifle designed by Lin Feng has achieved a range of 15 meters, successfully breaking the theoretical upper limit, so I say Lin Feng is a talent.

The coin coil model he designed broke the impossible and created a miracle, successfully increasing the effective attack distance of the coin bullet from 12 meters to 15 meters. This alone is enough to be praised. "

Hearing Professor Wang Shan's undisguised praise, netizen "Expecting Signal" showed a proud expression, as if Professor Wang Shan was praising him.

"Professor Wang Shan, do you think there is room for improvement in this coin-type electromagnetic rifle? After all, its attack range is a bit short, only 15 meters."

Reporter Chen Hang continued to ask his question, but this question made Professor Wang Shan shake his head:

“You may not know that current human technology is not very suitable for developing electromagnetic rifles, and the reason is still the problem of materials and batteries.

12 meters is only the theoretical limit. The ability to reach 15 meters is thanks to the coin coil model designed by Lin Feng and the control system that perfectly taps the potential of the hardware.

It is certainly possible to increase the attack distance at this time, but the energy consumed will definitely be greater than designing the first-generation coin coil model, and the funds consumed will also be more than the second generation, which can be said to be not worth the loss.

For example, our liquid lithium-ion batteries have reached their ceiling, and it is actually quite difficult to achieve a significant improvement in performance. The energy spent is not worth the gain.

That is why so many companies around the world are working so hard to develop graphene batteries and solid-state batteries, all wanting to become the dominant force in the new era.

So I think there is not much room for improvement for this coin-fired electromagnetic rifle, and the effective attack distance of 15 meters has reached its ceiling.

Even if it can be raised, it can only be raised by half a meter or one meter. It is almost impossible to raise it by more than two or three meters.

"I see. It seems that the coin-type electromagnetic rifle developed by Lin Feng is already quite perfect and has fully tapped the potential of coin-type electromagnetic rifles." Reporter Chen Hang nodded in understanding and then asked the last question.

“Professor Wang Shan, when Lin Feng first developed the handwriting robot, it caused a lot of controversy.

A professor named He even called Lin Feng a "black-hearted businessman who is of no benefit to the country". What do you think about this matter?"

“Bullshit! I don’t know what that handwriting robot is, but the coin-operated electromagnetic rifle developed by Lin Feng is definitely a great invention that has saved countless lives.

You may not understand the meaning of my words because you don't know a lot of relevant information.

Let me put it this way, do you know how many thieves are shot to death around the world? Do you know how many people are accidentally killed by guns every year?
It is impossible to count the number of people. According to the evidence, these people should not have been killed, but for various reasons they became innocent victims of the gun.

At this time, the coin-type electromagnetic rifle developed by Lin Feng can subdue the target remotely without harming his life, but only causing him some physical pain.

This is a disguised way of saving many lives, which has saved countless lives and brought merits.

In addition, if there were no coin-operated electromagnetic rifles, the police would not be able to shoot when the criminals were fleeing in panic due to many concerns, which would undoubtedly provide the criminals with an opportunity to escape.

At this time, with the coin-fired electromagnetic rifle, you can shoot without hesitation, which naturally improves the efficiency of subduing criminals and reduces the economic losses caused by criminals fleeing in a panic.

Therefore, it is a bit arbitrary for Professor He to deny Lin Feng’s life achievements and demerits because of the handwriting robot.

I think he should reflect on his words and deeds. After all, as a teacher, he should pay attention to his words and deeds. "

"it is good!"

"Expecting Signal" shouted loudly, applauding Professor Wang Shan's remarks.

Professor Wang Shan's words touched his heart. After all, it was too arbitrary for Professor He to deny Lin Feng just because of a handwriting robot.

Putting aside anything else, the coin-type electromagnetic rifle developed by Lin Feng at this time is something that will have a huge impact on Daxia and even the whole world.

So, that Professor He is probably just a person who is seeking fame and reputation. He has the title of professor but he has no shame.

Thinking about these things, he directly opened the Weibo APP and searched for Professor He. After finding Professor He, he @ed him like hundreds of thousands of netizens did, and said, "He is just seeking fame and reputation."

It didn't take long for these words to be seen by Professor He. When he saw the Weibo posts full of insults against him, he was stunned and puzzled at first, but he fell silent when he understood the truth.

I have to admit that he did make a small mistake. In a fit of anger, he arbitrarily called Lin Feng a black-hearted businessman who was of no benefit to the country.

Looking at the coin-type electromagnetic rifle developed by Lin Feng, Professor He naturally realized that he had made a mistake.

With a sigh, Professor He started to operate on the computer. He first deleted the original statement.

Then he honestly posted on Weibo to admit that he cared too much about the students at the time, so much so that he got so angry that he cursed Raymond Lam.

At this time, he admitted that he was wrong. He should not arbitrarily deny Lin Feng's life just because Lin Feng developed a handwriting robot.

But at the end of the article, he still called on Daxia to pay attention to handwriting robots and not allow such products to circulate on a large scale, otherwise it would be too late to regret in the future.
