Yes, it is an electromagnet.

Just like the stick before, it is a laser emitter.

Rao Xin remembers that when he was in junior high school, there was a popular toy at that time, strictly speaking, it could be regarded as a laser emitter.Install a battery inside, and then you can hold it on the wall and sweep it around.Every time when the class is over, the walls of the classroom are full of light spots shaking back and forth. At that time, they felt that this thing was like a laser sword of a Jedi knight.

The same laser, one is just a toy, and the other is a terrible weapon.

Rao Xin absolutely has no doubts that this weapon is feasible in principle—if antimatter is really used as the energy source.

Laser weapons are also an important research topic in the modern frontier military field. In satellite orbits, installing laser transmitters on satellites can be used to destroy enemy satellites; on the ground, with the help of image recognition and locking technology, laser weapons can also complete Anti-missile work - burning incoming missiles to disable their normal function - lasers as a weapon, of which equivalent functions are realized on earth.

In principle, there is not much difference between a laser launcher used as a weapon and a laser launcher used as a toy, it is just that the quantitative change produces a qualitative change.

In the same analogy, the laser weapons on the earth, and the laser weapons seen in the previous video, are only a step forward in terms of quantitative change-to let the special weapons that were originally thought to be used to accurately strike individual targets be further imagined It is a big killer at the level of nuclear weapons.

Just interpreting it from the perspective of creation, Rao Xin feels that if this movie really comes out, he will definitely buy a ticket to watch it immediately.

And the following videos are undoubtedly the expansion of the whole idea of ​​the film creator.

Since this effect can be obtained after laser quantitative change, the same is true for common electrical appliances in life.

On the earth, electromagnets that can only work in a small range at most show extraordinary effects in the environment in the video-in view of the fact that in the movie, the preset weapons are those flying swords, naturally, the electromagnet The biggest function of the sword is that it can be used as a shield to protect the sword.

Quantitative changes lead to qualitative changes. In real life, even the electromagnets used on cranes have an action range of only one meter. However, in the video, it can be clearly seen that Feijian is within a few tens of meters of the electromagnet. It began to be distorted by its position, and its trajectory began to change.Its suction is so strong that even after the sword is completely sucked, the phenomenon of twisting and deformation of the material occurs due to inconsistent surface stress. ——This is another large sum of money being burned.

The cup used to automatically heat and boil water can be used as a small metal smelting furnace.

As for the discharger, let alone artificially create dry lightning hundreds of meters, or even thousands of meters, as long as the function is sufficient, it can even create a lightning storm in a short time.The only problem is that the lightning release terminal can’t be solved well—there is no grounding in a gravity-free environment, and all the lightning will be directed to the surrounding small islands. The specific direction depends on the potential level of the target area.

Compared with laser weapons, these weapons are relatively weaker.

The purpose of their meeting this time is to discuss whether it is possible to use these weapons, as well as other weapons on the earth, to fight against the previous laser weapons under the premise that the energy problem can be solved.

Judging from these details, this project seems to be another theme of Earth vs. Aliens. ——It’s a very old-fashioned big theme, but the new direction and new ideas under the big theme are very interesting.

In addition, in terms of today's topic, this is a further extension of one of the topics in the meeting that Rao Xin participated in last time.

In the last meeting, the content they discussed was only general. The information that time was not as detailed as today. There are not only videos, but also specific technical data on the spot, including the conventional indicators of those electrical appliances, such as electromagnet power and The graph of the suction power, the input-output ratio of the discharger... There is a value that is very noteworthy. In all these electrical appliances, there is no upper limit to the power-that is, in theory, as long as the input is enough Energy, these electrical appliances can produce the same quantitative change.

This point is very scientifically reasonable-it is likely that the circuits inside those electrical appliances are all superconducting materials in the true sense, so there is no so-called power limit at all.

Rao Xin felt that he probably guessed why he was invited to participate in these consultation meetings. To a large extent, it was because of his experience in creating science fiction novels—these projects were probably the preliminary preparations for the film, and some technical experts were specially hired to perfect the settings. of.

But this conjecture was greatly shaken in the speech made by the American next.

Obviously, the thinking mode of that American does not start from the level of film creation.

Mr. America said: "Only in terms of weapon efficiency, these devices do not have the natural advantages of being weapons like lasers..."

"The most important reason is the energy release method of these electrical appliances. Most of the energy of the electromagnet is used to align the polarity of molecules, and the magnetic field itself decays very quickly with distance, and it is used as a defensive weapon against those flying The sword, it can be said that it still has some functions..."

"The premise is that the opponent has not developed a flying sword made of non-magnetic materials, but it is completely unreliable to defend against lasers. This is like trying to use a dagger to defend against a spear."

"The biggest advantage of the laser is that the energy projection form is very precise. This precision will produce a superimposed effect under the control of automatic information technology. Accurate energy plus precise release can be said to be a perfect piece of equipment. arms."

"Based on my previous work experience, the most reliable way to deal with laser weapons is to use a special anti-high temperature material as a protective layer, but this method is limited to targeting the energy level of weapons on the earth. If it is true as in the video According to the setting in the book, using antimatter as the energy source, the only feasible way is to cover with saturated firepower.”

"From the video, the biggest flaw of this weapon is not the weapon itself, but the people who use it. The speed of those flying people - yes, although they rely on flying swords, they can reach the speed of fighter jets, but compared to From a laser weapon, this speed can still be called its weakest point."

"I can make an analogy. A flying man using a laser can be compared to a sniper in a war. His shooting is precise and deadly. If we don't have the same sniper as a countermeasure, the most reliable way is to Use full firepower to cover all the dodge range of this sniper.""

Rao Xin suddenly had some doubts: "However, with the aiming speed of this laser, missiles and other weapons may pose little threat to him. There is no way to get close..."

"Then you don't need to get close," said the American. "As a straight-line weapon, lasers are naturally limited by their visual range. On Earth, there are not a few weapons that can be used outside the visual range."

Ok, I asked a silly question...

Rao Xin curled his lips, looked at the American, and then looked at Professor Shen and Professor Tian, ​​but they seemed to have no expression on their faces - probably not because they didn't understand, but because they probably already had the answer in their hearts.

"Nuclear weapons?"

"If you want to be conservative, it should be at least over a million tons," the American added. "Their flight speed is not slow, and they have a certain ability to avoid risks."

"Actually, there's no need to be so extreme, right?" Although there was a little bit of embarrassment just now, it didn't affect Rao Xin. The impact is very large. Artificially creating a large amount of dust haze can weaken its energy to a large extent and hinder his observation. "

Shen Changwen shook his head: "Anti-laser in smog? It may be feasible for laser weapons on the earth, but it does not exist in the set world."

"They have the ability to use electromagnetic waves to scan and locate. It can be said that everyone is a human-shaped radar. As for reducing energy--the weakening ability of dust haze is no stronger than that of shields-but even high-temperature-resistant ceramics, in the number of At a high temperature of one million degrees, it will only vaporize instantly."

"The nuclear weapons mentioned by Mr. Collander are an option worth considering...We can think in this way, but nuclear weapons..."

Shen Changwen frowned: "Nuclear weapons are indeed...it's a bit too extreme."

"That's right..." Rao Xin nodded understandingly, "You have to wait until the climax of the game or movie to use this kind of killer weapon."

Shen Changwen smiled.

"Maybe you can also consider Metal Storm," Kelland looked at everyone, and said scientifically, "A rapid-fire module, you can imagine it as a rapid-fire tool integrated with many machine gun barrels, using electronic control. The speed is as high as 1 million rounds per minute..."

"And the projectiles fired are smaller - an average of [-] rounds per second, which greatly exceeds the interception speed in the video. But I am not sure whether the speed shown in the video is the highest interception speed of this laser weapon , theoretically it can be strengthened."

"Of course, this idea can be expanded quantitatively. One metal storm is not enough, we can prepare two. With enough imagination, if we prepare more than one hundred metal storms, and prepare the bombing volume of these metal storms for ten seconds ..."

"Then within ten seconds, the barrage density per second will be as high as 50 rounds, an average of 1000 rounds per millisecond, which is more than 500 times its current response speed. This is also a way of thinking from quantitative change to qualitative change. [-] million One bullet, plus a hundred metal storms—it sounds incredible, but it's much more reasonable than a nuclear bomb."

Rao Xin was dumbfounded, who the hell is this Kelande?How come every word that comes out of his mouth can make people feel cold sweat on their backs.Looking at his attitude, it was obvious that this was not a place to discuss artistic creation—it was as if the staff were discussing the issue of firepower deployment and delivery.

But I have to admit that when he thinks of the scene where 50 bullets cover the same target in a second, he subconsciously feels excited. From the perspective of solving the problem, this Kelland's plan is useless. doubt, is quite doable.
