Yes, it is an electromagnet.

Just like the stick before, it's a laser emitter.

Rao Xin remembers that when he was in junior high school, there was a popular toy at that time, which was technically a laser emitter. Put a battery in it and sweep it around the wall. At the end of each class, the walls of the classroom were swaying back and forth, and at that time, they felt like a Jedi Knight's laser sword.

The same lasers, one just a toy, the other a terrifying weapon.

Rao Xin has absolutely no doubts about the theoretical feasibility of such a weapon, if it really uses antimatter as a source of energy.

Laser weapons are also an important research topic in the modern frontier military field, in the orbit of the satellite, the satellite is equipped with a laser launcher, which can be used to destroy the enemy's satellite; On the ground, with the help of image recognition and locking technology, laser weapons can also do anti-missile work - scorching the incoming *, so that it loses its normal function - laser as a weapon, the equivalent of which is realized on Earth.

In principle, there is not much difference between a laser emitter used as a weapon and a laser emitter used as a toy, but the quantitative change produces a qualitative change.

By 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 - making special weapons that were originally thought to be only used for precise strikes against individual targets further imagined as nuclear-weapon-level mass killing weapons.

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

And the next videos, without a doubt, are the expansion of the whole idea of this film creator.

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

On Earth, electromagnets, which can only work in a small area at most, show an extraordinary role in the environment in the video - given that in the movie, the preset weapons are those flying swords, then naturally, the biggest role of the electromagnet is that it can be used as a shield to protect the sword.

In real life, even if the electromagnet used on the crane has a range of less than one meter, but in the video, it can be clearly seen that the flying sword begins to be distorted by the position within a few tens of meters close to the electromagnet, and the trajectory begins to change. Its suction power is so strong that after the sword is completely absorbed, there is even a phenomenon of distortion and deformation of the material due to inconsistent surface stress. - This is another large amount of money that has been burned.

The cup, which is used to automatically heat boiling water, can be used as a small metal smelting furnace.

As for the discharger, not to mention, it can artificially create dry lightning of hundreds of meters, or even thousands of meters, and as long as the function is sufficient, it can even create a lightning storm in a short time. The only problem is that the release terminal of lightning is not well solved - there is no grounding in a gravity-free environment, and all lightning will immediately direct to the surrounding islands, and where to direct it, only depends on the potential of the target area.

Compared to laser weapons, these weapons are relatively weak.

And the purpose of their meeting is to discuss whether it is possible to use these weapons, as well as other weapons on the earth, to confront the previous laser weapons on the premise that the energy problem can be solved.

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

In addition, from the perspective of today's topic, this is a further extension of one of the topics in the last meeting that Rao Xin attended.

In the last meeting, the content they discussed was only general, and the information was not as detailed as today's, not only the video, but also the specific technical data on the site, including the conventional indicators of those electrical appliances, such as the graph of electromagnet power and suction, and the input-output ratio of discharger...... It's worth noting that there is no upper limit to the power of all of these consumers – that is, theoretically, they can produce the same amount of variation if enough energy is inputted.

This is scientifically sound – it's likely that the circuitry inside the appliance is a real superconducting material, so there's no such thing as a power limit.

Mr. Rao felt that he had probably guessed why he had been invited to these consultations, in large part because of his experience in writing science fiction novels — projects that were presumably pre-film preparations, with some technical experts to refine the setting.

But this conjecture was greatly shaken in the following speech, the American.

Obviously, the American mindset did not start from the level of film creation.

"In terms of weapon efficiency alone, these devices do not have the natural advantage of lasers as weapons......

"One of the most important reasons for this is the way the appliances themselves release energy. Most of the energy of the electromagnet is used to arrange the molecular polarity, and the magnetic field itself decays very quickly with distance, and it can be said that it has some effect when it is used as a defensive weapon to defend against those flying swords......"

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

"The biggest advantage of the laser is that the projection form of energy is very accurate, and this accuracy will produce a superposition effect under the control means of automatic informatization, and the precise energy plus the precise release can be said to be a perfect weapon."

"As far as the experience of my previous work is concerned, the most reliable way to deal with laser weapons is to use a special high-temperature resistant substance as a protective layer, but this method is limited to the weapon energy level on the earth, if it is really as set in the video, with antimatter as the energy base, then there is only one feasible way, saturated firepower coverage."

"Judging from the video, the biggest flaw of this weapon is not the weapon itself, but the person who uses it. The speed of the Flying Men - yes, even though they can reach the speed of a fighter with their flying swords, it is still its weakest point compared to laser weapons. ”

"I can draw an analogy to a flying man who uses a laser, and he can be compared to a sniper in war, who shoots accurately and deadly. If we don't have the same sniper as a counter, the most reliable way is to cover all of the sniper's dodge range with sufficient firepower. ””

Rao Xin suddenly had a little doubt: "However, with the aiming speed of this laser, the threat to him from a weapon like * may be very small, and there is no way to get close to it, so ......"

"Then there is no need to approach," the American said, "and the laser, as a straight-line weapon, is naturally limited by the range of sight." On Earth, there are not a few weapons that can be used beyond the visual range. ”

Well, I asked a silly question......

Rao Xin pursed his lips and looked at the American, and then at Professor Shen and Professor Tian, but their faces seemed to have no expression at all—probably not because they didn't understand, but because they probably had this answer in their hearts.

"Nuclear weapons?"

"If you are conservative, it should be at least more than one megaton," the American added, "and their flight speed is not slow, and there is a certain ability to avoid danger." ”

"Actually, it doesn't have to be so extreme, right?" Although there was a little embarrassment just now, this did not have any impact on Rao Xin, and he expressed his opinion on this issue, "As a straight-line weapon, laser weapons are greatly affected by obstacles. Artificially creating a large amount of dust and haze can greatly weaken its energy and hinder his observations. ”

Shen Changwen shook his head: "Haze anti-laser? Laser weapons on Earth may work, but they don't exist in the world. ”

"They have the ability to use electromagnetic waves to scan and locate, so to speak, everyone is a humanoid radar. As for the energy reduction - the weakening power of the dust haze will not be stronger than the protective material - but even the ceramics that are resistant to high temperatures will only vaporize instantaneously at millions of degrees. ”

"Mr. Collander's nuclear weapons are an option worth considering...... We can think along these lines, but nuclear weapons ......"

Shen Changwen frowned: "Nuclear weapons are indeed ...... It's still a little too extreme. ”

"Yes to ...... too" Rao Xin nodded understandingly, "This kind of big killer has to wait until the game or the movie * to use it." ”

Shen Changwen smiled.

"Maybe consider Metal Storm," Colland said, looking at everyone, "a rapid-fire module, you can imagine a rapid-fire tool with many machine gun barrels integrated, electronically controlled, with a rate of fire of up to 1,800,000 rounds a minute......"

"And the projectiles fired are smaller - an average of 30,000 rounds per second, which significantly exceeds the speed of interception in the video. But I'm not sure if the speed shown in the video is the highest interception speed of this laser weapon, which can theoretically be strengthened. ”

"Of course, this idea can be quantitatively expanded, one metal storm can't work, we can prepare two. Use your imagination enough, if we prepare more than a hundred metal storms, and prepare these metal storms for ten seconds to drop bombs......"

"In those ten seconds, the density of the barrage per second will be as high as 500,000 rounds, an average of 500 rounds per millisecond, which is more than 1,000 times its current reaction speed. This is also a way of thinking that quantitative change can achieve qualitative change. Five million rounds of ammunition, plus a hundred metal storms - this sounds incredible, but it is much more plausible than a nuclear bomb. ”

Rao Xin's whole person was stupid, where is this Kelander sacred? How to say every word that came out of his mouth, listening to it could make people feel a cold sweat on their backs. He looked at his attitude, and it was clear that this was not the place to discuss artistic creation—it was as if the General Staff was discussing the issue of firepower and delivery.

But I have to admit that he subconsciously felt excited at the thought of half a million bullets covering the past towards the same target in one second, and from the point of view of solving the problem alone, there is no doubt that this Curlander's plan is quite feasible.
