Chapter 464 Faraday Cage Induced Electromotive Force and the Evil Spirit
This time, Xius was really dumbfounded.
Is there something evil in electricity? Wouldn't the world's technology be locked in the pre-electrical age? Did the use of energy end with the steam engine? Without electric motors and circuits, there would be no possibility of developing various chips, let alone computers. The pinnacle of the mechanical age was the difference engine developed by Babbage, which was steam-driven and purely mechanical. It looked spectacular, but in terms of computing power, it couldn't even compare to the 9.9 yuan electronic watches sold on the street.
Without electricity, there would be no magnetism. No matter how hard he tried to develop, the upper limit of this world was stuck there. He couldn't even touch the edge of the speed of light. All he could do throughout his life was to bully the natives in this world.
The sea of stars? Don’t even think about it.
The prince's words were like a bucket of cold water poured over his head, and Hughes finally came to his senses.
He took a few deep breaths before suppressing the uneasiness in his heart.
After the impetuous emotions disappeared, rationality returned to this body.
"Wait, I did some simple experiments and successfully created electricity?"
Hughes had thought about making electric motors before, but this still requires certain processing accuracy. Castel has not yet been able to solve the tolerance problem of the rotor and stator. If the accuracy is not enough, it is easy to have poor dynamic balance. Not only will the life of the motor be short, but it is also easy for the motor to run away and injure people.
The steam engine does not have so many problems. The tolerance is not too outrageous. If there is no coal, just burn wood. It highlights simplicity and convenience.
But this did not prevent Hughes from making a hand-cranked generator. He also tried to make chemical batteries and planned to build an aluminum electrolytic plant in the future.
However, these are all kept in the laboratory and have never been put into the production line, so Xius is not sure what this "evil thing" in electricity is.
The prince shook his head. "The experiment you are doing should not be large-scale, right? Some organizations have been researching this kind of trendy thing before, but they soon encountered a lot of trouble. The most famous one should be the accident caused by the Fire Moth."
The corner of Zeus' eye twitched. Why is it that there are always fire-chasing moths in every experimental accident?
The prince also looked at Hughes with some caution. He certainly knew that this border earl was in collusion with the Fire Moth, but who cared? As long as he could provide him with weapons and help Blood Harbor industrialize, he would not say anything, not to mention that he had an unclear relationship with the cultists, even if he admitted that he was the prince of the evil god.
Besides, it looks like he won't admit it even if you beat him to death.
"Fire Moth has done a lot of experiments on electricity before, and has developed a series of materials that can resist electricity. I'm not sure what they are specifically."
"Insulator?" The prince was not sure, but Hughes was very familiar with these and even knew the electrical conductivity coefficients of many materials.
"Insulator? Is that what it's called? Never mind, it's not important. Anyway, they used these materials to make a set of armor. According to their calculations, this armor is enough to resist the power of thunder, and then..."
"They were going to be struck by lightning wearing this armor?"
The prince nodded: "Yes, it turns out that it is impossible to defend against it!"
Xius covered his face, feeling a bit amused and helpless: "I thought it was something else, but it turned out to be this kind of thing - it's not that the materials are not insulating, it's because they mistook strong electricity and weak electricity for the same thing."
The "insulation" of any insulating material is only relative. Insulating materials have a breakdown voltage. Lightning is likely to directly penetrate the armor and electrocute the person to death.
And even if the armor can withstand it, the people inside may not be able to withstand it.
Even if the armor itself is not penetrated, the huge current generated when lightning hits the armor may generate current inside through electromagnetic induction or capacitance effect. The high voltage at the moment of lightning strike may form an electric potential difference between the inside and outside of the sphere, causing an electric arc inside.
The people inside are not isolated.
"They chose the wrong material - on the contrary, they should use conductors, that is, materials that are not anti-electrical, to make a fully enclosed armor that completely locks the person inside. This is the real way to deal with lightning."
This is actually the principle of a Faraday cage.
A Faraday cage is a conductive closed structure. The metal cage forms an equipotential body and the internal electric field strength approaches zero. When lightning strikes, the current flows along the outer surface of the cage and will not penetrate the internal space.
Modern houses can actually be considered Faraday cages. The steel bars in the walls are crisscrossed and connected, so there is basically no safety issue when hiding in the house during lightning. In an emergency, hiding in a car is also safer than hiding in the open air.
Xius knew a little about this, and had even studied whether he could get one if he had survived the thunderstorm. "So don't worry, they just don't know enough about thunder and lightning. The difference between different magnitudes of electricity is huge."
In fact, most physics have such problems. Classical physics is not applicable in a large number of situations such as high-speed motion, microscopic conditions, strong gravitational fields, etc. To put it simply, it is only applicable to phenomena that can be seen in daily life.
This situation has occurred in many disciplines. When research reaches a certain point, it is suddenly discovered that all formulas are no longer applicable, and all previous research has become waste paper. The worldview of many people is about to collapse.
After all, this is what I personally discovered: "Physics no longer exists."
But science is a methodology for understanding the world. We should objectively analyze what the material world is like. The fact that physics no longer exists only means that past physics can only go so far, and the door to a new world is right in front of us.
Zeus spoke a lot to the prince in a very eloquent manner. It might be difficult to let people in this world understand the history of scientific development, but many concepts are common. The prince was not a conservative person, and his eyes were full of surprise when he listened.
"I see. This angle is really wonderful. It is really exciting to see the real world." The prince held Hughes' hand and laughed, "I can now understand the Fire Moth's thoughts to some extent. Chasing knowledge is really interesting. Then I'll say goodbye to you, Sir Hughes. It's getting late. I plan to go back and study electricity."
Hughes smiled and nodded: "Electricity is very dangerous, please be careful."
"Don't worry, I will mobilize the port guards to surround the test site."
"Harbor Guard?"
Xius's smile froze for a moment, and he suddenly felt as if he had overlooked something.
With so many organizations in this world, would they really stop their research on electricity completely because of an experimental accident? What about the Fire Moth, would they just give up after failing? Hughes' throat rolled and he asked, "Why do we need to mobilize the Port Guard?"
"That's of course because those who are electrocuted are transformed into evil creatures. Don't worry, my harbor guards will have no problem dealing with those monsters."
