Seeing such a magnificent scenery, Yiyi couldn't help but sigh again, so she asked again: "Brother Qi, we also saw a lot of lights last night. Is this the case in the whole city?"
With so many lights, how much lamp oil must be burned in one night? Are everyone very rich? Don’t they know that frugality is a good habit for running a household?" This is another conceptual knowledge question.
"Hahaha! Yimei, this kind of lamp is called an electric lamp here. It doesn't need to burn oil. It uses a new energy source called electricity. As long as the power is connected, these bulbs will light up, and
The brightness far exceeds the brightness of an oil lamp.
The light bulbs we see now require very little electrical energy, so only people in this world dare to install so many light bulbs. This consumption does not waste much electrical energy at all.
Precisely because it consumes very little energy, people use electric lights to decorate the night scene so beautifully. In the human world, this is called night lighting project, which uses lights of different colors to satisfy everyone’s visual experience.”
"Brother Qi, what is electric energy? Is it another substance like fuel, and the reserve is very large, otherwise everyone wouldn't waste it like this, right?" Yiyi was naturally very interested because she was younger.
Eager to learn new knowledge.
"Yimei, electric energy is not fuel. Fuel is a non-renewable energy source, but a large part of electric energy can be continuously regenerated. In today's human world, electric energy is mainly transformed by using water energy, wind energy and solar energy.
The principle of converting wind energy and water energy into electrical energy is relatively easy to understand. That is to use the force of wind and water flowing down from a high place to drive the engine and rotate the engine to generate electrical energy.
As for the working principle of the generator, since you have no theoretical basis in this area, it will be difficult for me to explain it clearly to you for a while. All you need to know is that it can convert other energy into electrical energy.
To convert solar energy into electrical energy, a large number of solar receiving panels are laid on the ground to collect the sun's light energy and convert it into electrical energy, which is then transported to various places for people to use through transmission lines.
You must have seen some transmission lines in the past two days, which are the kind of long lines that are erected in mid-air and extend side by side for a long time. Through those long lines, electrical energy invisible to the naked eye can be transmitted to various places.
Then conductive wires of different thicknesses transmit electric energy to each bulb. In this way, all the electric bulbs will be lit by electric energy, forming various lighting effects of different colors, thus embellishing the beautiful scenery.
In addition to these three types of sustainable renewable energy that can be converted into electrical energy, there are many non-renewable energy sources that can also be converted into electrical energy, such as combustible firewood, fuel oil, gas, coal, and even garbage, etc.
It releases energy through combustion, drives a generator, and converts heat energy into electrical energy for people to use.
Electric energy can not only light lights, it can also be used to cook, stir-fry, drive vehicles, adjust temperature, charge mobile phones, etc. Anyway, electricity has a wide range of uses and touches every household and everyone's life."
"Brother Qi, the electric energy you mentioned is really amazing. I didn't expect that in this human world, although there is no spiritual energy and no one has any cultivation, they know so many things and have developed so many new things.
Things for your own use and enjoyment, such as various vehicles on the street, ships in front of you, various lighting fixtures, etc.
By the way, Brother Qi, there are so many light bulbs, how are you going to blow them out then? Besides, I see that there are no gaps in each light bulb, and there is no way to blow it out! It’s not like smashing them all, right?
!”
"Hahaha! Yimei, why do you always think about problems in terms of fuel lamps? Electricity is a wonderful thing. As long as the transmission line is disconnected, it will disappear without a trace in an instant.
For this reason, scientists in the human world have designed switch equipment with various functions. From the manual opening and closing switches at the beginning to the current remote control switches, the switch can be operated remotely at any time.
Just like when staying in a hotel, I teach you how to use the remote control. As long as we press it with our finger, we can turn on the power, and press it again to turn off the power. For example, the mobile phone we use can perform these operations.
The method is that we turn on the specific control keys on the mobile phone and first match it with the device we need to control, and then we can control it. This kind of remote control command device can even be implemented thousands of miles away."
"Is this possible? It can be controlled thousands of miles away. Is it more powerful than the peerless masters in our cultivation world? Even those masters who have transcended the body shaping realm cannot control it thousands of miles away!"
"Yimei, there are very few impossible things in this world. Many things are not impossible, but unexpected. These people in the human world are not weak in intelligence. On the contrary, they may be smarter than us cultivators.
many.
Because they were unable to practice, they used their intelligence and wisdom in the exploration and research of things, and this led to many inventions, especially the killer weapon they created, which is what practitioners in the middle stage of the Body Shaping Mirror also
Neither can resist it.
Therefore, everyone should try to keep a low profile in the future, and must not force them to use lethal weapons, which can endanger life safety. As far as I know, there are several weapons that can easily destroy the entire small world of the Qu clan.
.
Moreover, the timeliness of this kind of destruction is still very long, that is, it cannot be recovered for hundreds of years, because once these types of weapons explode in power, any living and dead objects within a radius of hundreds of kilometers around the center of the explosion will be destroyed.
Fortunately, the materials for making these weapons are scarce, the manufacturing costs are extremely high, and they are not easy to use. Unless you don't even care about your own safety, it will be difficult to form a continuous attack.
In addition, once these weapons are used, the later harm will be difficult to eliminate, so people are opposed to the use of this type of weapons. They are not as easy and flexible as the use of martial arts and combat skills, and can be easily hit at any time.
These weapons also have a fatal weakness, that is, in the initial stage of being launched, they can easily be restrained and aborted, causing themselves to be harmed. Even if they are successfully launched, they will not have much effect on practitioners who have transcended the body shaping realm.
.
At present, the cultivation realm of several of us is at least the fourth level of the Body Shaping Realm or above. Although these weapons have a deterrent effect on us, as long as we are not hit by continuous direct hits, there is not much problem in saving our lives.
Besides, as long as we don’t take the initiative to stir up trouble, people will not use these types of weapons easily. Another important point is that these weapons can only be used at medium and long range. If used at close range, it will harm both others and ourselves.
Therefore, you don’t have to be afraid at all. Once we have a conflict with them, we should try our best to fight the other side at close range, so that the other side will not dare to use this type of weapon, and then the initiative will be entirely in our hands."
"Young Master, as far as I know, the explosive power of black powder is very powerful, but we can easily resist it. Is there anything more powerful than black powder? How powerful should it be?"
"That's because your Qu family has no research in this area, so you only know about black powder. But in the human world here, people have also developed more powerful explosives such as ammonium nitrate, TNT, Tequer, and Octogen.
Explosives.
Over the past hundred years, atomic nuclear weapons such as atomic and hydrogen bombs have been developed. The power of nuclear weapons alone is at least as powerful as the instantaneous explosion of tens of thousands of tons of TNT, and the most powerful ones can even reach millions of tons.
The power of simultaneous explosions of TNT.
The TNT I am talking about here is already the name of an explosive that is more powerful than black powder. Because of its wide range of use, people here use its explosive power as a calculation benchmark to measure other explosives.
On top of nuclear weapons, there is a hydrogen bomb that is more powerful than it. Just from the way it detonates, you can guess how powerful the hydrogen bomb is. A small nuclear weapon is placed inside the hydrogen bomb to detonate it.
of.
Mr. Ling, you can imagine that if you use a nuclear bomb just to detonate it, will its power be less? If the power is not far greater than that of a nuclear bomb, then why waste a nuclear bomb to detonate it?
Wouldn't it be more cost-effective to directly increase the explosion yield of the atomic bomb?" Zhi Lingqi took the trouble to explain the situation of attack weapons in the human world to Ling Lao and Yiyi, because this is his old profession.
