Question 1: What does the Nautilus use to generate electricity in Twenty Thousand Leagues Under the Sea? Is it possible to use sea water to produce electricity? By refining sodium from the sea, batteries are made to produce electricity. The Nautilus was at the time the only submarine in the world described in Verne's classic science fiction novel "Twenty Thousand Leagues Under the Sea" (also transliterated as the Nautilus). The Nautilus is described in the novel Delius is a slender, spindle-shaped submarine. 70 meters long and 8 meters wide, it has excellent navigation performance and can reach a maximum speed of 50 knots per hour. This is an ideal submarine. The ship is powered entirely by electricity. Electricity is extracted from seawater and sodium is mixed with mercury to form a battery that replaces the original battery. A zinc alloy is obtained after havingr been transformed into electricity. stored in piles.
Food consists entirely of fish, seaweed, etc., so the crew's energy and daily necessities come from the sea. They do not need land-based supplies at all and can sail the sea indefinitely. The Nautilus has a huge compressed air storage tank
inside, allowing it to remain submerged on the sea floor for several days without having to surface. The interior of the ship is spacious and comfortable, and there is even a museum and library! The ship's weapon is the steel horn on the bow. With the high speed and strong outer hull of the ship, the power of the horn is very huge. At the end of the novel, the Nautilus relies on it to counterattack enemy warships that attack it. . , the Nautilus hit the side of the battleship at high speed, and the impact angle penetrated the hull
Question 2: What type of power does the Nautilus use in Twenty Thousand Miles Under the Sea? Essentially, it comes from the sea. By refining sodium from the sea, nanobatteries are made to produce electricity.
Question 3: What does the submarine Nautilus, which Captain Nemo secretly built on a deserted island in the ocean, rely on to produce electricity? in Twenty Thousand Leagues Under the Sea? The principle is still the Bunsen battery, but the zinc used in the cathode of the Bunsen battery is replaced by sodium amalgam
Question 4: How does Verne depend water to produce electricity in Twenty Thousand Leagues Under the Sea? Using Canal Engineering to Support the Engines
Question 5: How does a submarine generate electricity at Twenty Thousand Miles Under the Sea

The original text is as follows:
“But, Captain, your ship is moving si quickly, which is not compatible with the power of electricity. Until now, electricity is still very limited and can only produce very limited power!"
"Professor," replied Captain Nemo, "my electricity is not ordinary electricity, it "What can I tell you?"
"Sir, I don't want to ask you any more questions, I just feel that it's a very strange effect. But I want to ask a question. If it's not a question, you can leave it unanswered. Of course, the material you use to produce this strange driving force will soon be exhausted. since you have nothing to do with the soilHow to contact me? I have no more. How to restock them? »
“It is possible to answer your question. " Captain Nemo replied: "First of all, let me tell you that there are deposits of zinc, iron, silver, gold and other minerals on the seabed, and that their development is notnot impossible. But I don't depend on these metals on earth. I just need the sea itself to supply me with raw materials to produce electricity. ,
“Do you want to get supplies from the sea?”
"Yes, Professor, I have several methods. For example, I can connect metal wires buried at different depths to form a circuit. , the metal wire is exposed to different heat to generate heat 'electricity: but I usually use another method that is more convenient and practical ”
“What method is it
“You. know the composition of sea water. A kilogram of sea water contains 96.5% water, about 2.7% sodium chloride, and the rest is a small amount of magnesium chloride and potassium chloride, magnesium sulfate, sulfuric acid and carbolic acid. I can see that sodium chloride is present in considerable quantities in theseawater and what I extract from seawater is sodium which I use to make what I need."
"Sodium?"
“Yes, sir. Sodium is mixed with mercury to form an alloy that replaces the zinc needed in Bunsen batteries. There will be no loss, only the sodium will be consumed, but the seawater itself provides the sodium I need. In addition, I can also tell you that sodium batteries should be the most powerful, and their electrical power is several times that of zinc batteries. p>
"Captain, I understand your advantage in obtaining sodium in this situation. Sea water contains sodium 6 pairs. But you still have to do it, that is, take it out. How is it done Of course, your battery can do this kind of work, but if I'm not mistaken, the amount of sodium consumed by the electric machine is probably greater than the amount of sodium you consumez for production. In fact, more sodium than you can produce!"
"Professor, I don't use batteries, I just use the heat from coal on earth,
“On land?” I said insistently.
"Let's just say it's coal on the seabed." Captain Nemo replied.
"Can you mine coal under the sea?"
"Mr. Aronas, you will see me mining. I just ask you to be patient for a while, because you have time and can wait I just ask you to pay attention to this: I take everything from the ocean, I use the ocean to generate electricity and I provide the Nautilus with heat, light and. electricity. Electricity brought the Nautilus to life”
“But electricity can’t provide the air you breathe, can it?”
“Ha! I can also produce air for my own consumption, but that’s not necessary because I can float atthe surface of the sea whenever I want. However, even if electricity doesn't provide me with breathable air, it can activate a powerful air pump to send the air to a special location. Sealed chamber, so I can stay in the depths of the sea for that long that I need it."
"Captain," I replied, "I can only admire you. You obviously found something humans. can find something in the future that is the true power of electricity. »
Question 6: How does a submarine 20,000 miles under the sea rely on electricity generation? ambient temperature. Nuclear energy can be used to produce electricity. This is similar to the pioneer launched by the United States in 1972. The power generation method of the 10 spacecraft is the same, located in space more than 10 billion kilometers from space. earth. It flies at a speed of 44,064 kilometers perhour relative to the sun. Although its operation is deteriorating, it still functions normally and produces nuclear energy. The engine continued to recharge its batteries (there was no sun there) and continued. to send weak signals to Earth. It was the first man-made object to successfully escape the solar system.
Question 7: What is the source of energy for the 20,000 Miles. Under the sea vessel? The energy of ocean water
Water has surface tension. What can be done with this water feature?
1. One of the first ways to power mechanical engines was steam. Although it is not very effective, after the collapse of human civilization, many things will be used. The steam engine can use heat to boil water and turn it into steam. then the steam expands to push the piston or other mechanical elements to pproduce electricity
2 Internal combustion generator
Internal combustion generators are quite common these days and run on gasoline. propane, diesel or natural gas. They work a bit like a car engine: A small explosion moves a piston, which in turn causes a magnet to produce electricity. Just turn it on when electricity is needed.
< p>3. Wind powerThey are often called “hybrid systems” because they combine wind and solar power. Both methods of solar power generation are intermittent. An interesting alternative is a wind-water hybrid system. wind power to pump water into high troughs and release the water to generate kinetic energy
4. Hydropower
Humans have been harnessing the power of rivers and streams for some time, such as building huge hydroelectric dams.ics. Many companies are committed to building systems that utilize rivers and streams. Domestic water turbines, among the most efficient models, are enough to power an average-sized home. electricity 24 hours a day, whatever the weather conditions.
5. Solar Energy
p>The sun is perhaps the most reliable source of energy because it outlasts humans by billions of years. Solar home systems do not store the excess energy they generate, but return that energy. The main electricity grid is gone and batteries are needed to store it. Inventory of 7 post-apocalyptic developments.Electric method
Water has surface tension. What can be done using this feature of water?
Insects use surface tension to float on water. Underground stems use phenomena to transportter water and nutrients. Liquids can use surface tension to take on a spherical shape. Humans can use surface tension to automatically increase the liquid state, making the density very high. Large objects float.
During my morning exercises, I observed water droplets left on the leaves of flowers and plants by the roadside. These water droplets are oval or spherical. Especially on lotus leaves, the water droplets will continue to sway with the leaves, turning over and over on the leaves, and the shape will change, but basically you can see that the shape tends towards the angle of a sphere. The water droplets do not spread and form a shrinking water layer on the surface of the leaves.
We sometimes put water in a cup. When the water reaches the neck of the bottle, more water can still be added. The watermust obviously be higher than the neck of the bottle and will not be. overflow. In fact, everyone can understand this situation based on surface tension.
So what is surface tension? How do they produce the appearance of such forces? According to modern physics, the concept of surface tension is: The force that promotes the convergence of the liquid surface is called surface tension. The surface of the liquid is adjacent to the middle of two parts and the force pulls each other in a unit length.
The direction of surface tension intersects the liquid level and is perpendicular to the line of intersection of the two parts. If the liquid level is a plane, the surface tension is on that plane. an inclined plane, the surface tension Just on the cross section of this inclined plane. It is customary for people to call the interface between gas and liqfluid, gas and solid objects, surface.
Generally, due to differences in the natural environment, molecules on the surface and molecules inside the object (liquid water groups also belong to an object) support different forces. The coforce between a water molecule inside a body of water and the interaction force between surrounding water molecules is zero. But this is not the case for a water molecule on the surface. Since water molecules in the upper space are less attracted to it than molecules in the internal liquid, the co-force on the molecule is not equal to zero. The direction of the force is directed vertically towards the interior of the liquid, which results in an automatic decreasing tendency of the liquid surface area. This shrinking force is called surface tension.
When water molecules volatilize into fine particles, their surface expandsand many internal water molecules move toward the surface. These dispersed molecules have more surface energy. To break away from this surface, molecules must overcome the constraints of this surface energy. Surface tension is a characteristic of chemical substances and its size is related to the temperature and properties of two different substances.
Surface tension is a major manifestation of molecular forces. This occurs at the boundary between liquid and gas, liquid and solid. Indeed, the liquid molecules of the surface layer are in a particular situation. The molecules inside the liquid are basically close together and the molecules often maintain a stable distance if they are slightly further apart opposite phases will form. Hell, if you get closer they repel each other . This determines that liquid molecules do notdo not propagate infinitely like gas molecules, but can only vibrate and rotate around the equilibrium position.
Molecules near the surface of the liquid are only affected by the effects of molecules inside the liquid, and their carrying capacity is uneven, allowing molecules with relatively high speed to pass through liquid easily. liquid level and turn into vapor. As a result, the molecules on the surface of the liquid (the molecular distribution of liquid chromatography (liquid chromatography in contact with gas) is less dense than the internal molecular distribution.
This is also relative to the regions molecules inside the liquid, which are in a unique situation. The repulsive forces between the molecules in the surface layer decrease as the distance between them increases, and the attractive force between the molecules prevails in this unique layer. .
The direct driving force between any two parts of this surface layer promotes the tendency of the liquid surface layer to shrink. Due to the effect of surface tension, the liquid surface always tends to become as small as possible. therefore the liquid in the air Small liquids generally take the shape of spheres. The expression of this surface tension can seem very difficult to understand for some lay people.
