"Its name is..."
"The earth sprays water!"
[? ?]
[? ? ?]
[God is squirting!]
[The name of tiger and wolf.]
[It’s better to call it Earth**.]
[Are you kidding me?]
[]
[Listening to the name, I know why the scientific community cannot create it.]
[As expected of you.]
[As expected of you +1.]
[All rise! Say goodbye to the veteran driver!]
"That's right, it's called the earth's spray." Chen Yu turned sideways and let the camera capture the panoramic view of the blue cylinder: "It has a more appropriate name - the tide of Mother Ocean."
"Everyone will definitely not understand why this product has such a name, but when I explain its principle, everyone will understand."
"As we all know, the cost of rocket launch is very high. According to current standards, if it is very economical, it costs 20,000 US dollars to launch 1 kilogram of material. Fifty kilograms for a person will cost 1 million US dollars. If it is Qiao Biluo No matter how wealthy a country is, it won’t be able to afford such a heavyweight astronaut for long.”
"But if it is replaced by a space elevator, the cost will plummet. After calculation, it only costs 190 US dollars to lift 1 kilogram of matter into space. A hundred times difference! Even if we ordinary people want to travel in space, tickets It’s also affordable. So you can imagine the officials’ yearning for the sky elevator.”
"Okay." Chen Yu clapped his hands and pointed at [Earth Spraying Water] and said, "It's its turn. How much will it cost to use this product to go to space?"
"… for free."
As soon as he said this, not to mention the audience, even the professors in the castle almost bit their tongues.
"Yes, no money."
Chen Yu emphasized: “Not only does it cost no money, it also makes money.”
"Because it uses water to spray the load into space. Water is endless in the earth's oceans and can be reused. So it is also called the tide of the mother ocean. This is a gift from nature. "
[I laughed.]
[Are you finally going to start a pyramid scheme?]
[Click to play for a year, and the equipment does not cost a penny.]
[Hello everyone, my name is Zhazahui.]
[Does it really cost nothing? Give me money to go to space?]
[The UP owner said the cost should be very low, right? It’s impossible not to spend a penny.]
[Complete nonsense! Spraying stuff into space with water? Did you think it was the fountain on Europa last time?]
[Imagination. Not to mention pushing matter, simply spraying water into space tens of thousands of kilometers, this kind of energy is enough for a rocket to be used a thousand times.]
[Space fountain? This is pseudoscience emmmm...]
[It’s not that I don’t trust the anchor, but it doesn’t make sense in theory.]
[Don’t pretend to understand, okay? Are you better than the anchor?]
[It’s not a question of whether you’re awesome or not, no matter how awesome you are, you can’t go against the basic common sense of physics...]
Raising his wrist and looking at the hype barrage, Chen Yu shrugged: "I know that most people don't believe it. So now, I will introduce the principle of this product in detail to let everyone understand what imagination is. Create worlds.”
After finishing speaking, he summoned Hermione, grabbed the staff from her hand, and drew a picture in the air while talking: "First of all, we need to know the most basic chemical principle. Water, with the chemical formula H2O, is the simplest hydroxide compound. It is a colorless, tasteless and odorless liquid with a freezing point of 0°C and a boiling point of 100°C under standard atmospheric pressure. The density is maximum at 4°C."
"Water contains hydrogen, and hydrogen is a fuel. When mixed with oxygen, it explodes when exposed to fire. All rockets today also use hydrogen-oxygen fuel."
"Then an interesting point arises here! Why not split the hydrogen out of the water?"
As he spoke, Chen Yu drew formulas one after another in the air, talking to the stunned audience of 20 million people.
"It can be decomposed. There are many methods, and they are all very simple. For example, electrolysis, 2HO is electrified with 2H↑+O↑, and hydrogen and oxygen can be decomposed. But according to this formula, it can be concluded that the chemical energy stored in the product is Higher than the reactants. According to the principle of energy conservation, it is difficult to have a catalyst that can directly decompose water into hydrogen and oxygen while ensuring that the amount of the catalyst itself remains unchanged."
"In human terms, the investment exceeds the expenditure. It is unrealistic."
"In addition to electrolysis, several other methods of decomposing hydrogen require material contact. For example, metallic sodium (Na), metallic aluminum (Al), and metallic iron (Fe)."
"Their formulas are: 2Na+2HO—2NaOH+H."
"2Al+6HO heats 2Al(OH)3+3H↑."
"3Fe+4HO (g) high temperature Fe304+4H↑."
Writing three sets of formulas in the air with particles, Chen Yu pointed to the first formula and said, "Did you see it? The latter two, aluminum and iron, need energy output if they want to decompose with water into hydrogen. Only metals Sodium! It can decompose into hydrogen as long as it comes into contact with water!"
"Hydrogen! It's the fuel!"
Putting down his staff, Chen Yu pointed to the blue ocean under the white mist in the distance: "There is infinite sodium in the ocean. We only need to extract it and merge it with water, isn't it equivalent to endless fuel?"
Without giving the audience room to think and refute, Chen Yu continued: "To obtain metallic sodium, in modern industry, most of them use the Downs method, that is, adding calcium chloride to sodium chloride (salt) solution. , electrolysis generates metallic sodium at a high temperature of 500°C and a voltage of 6V. The metallic sodium is at the cathode, and chlorine is generated at the anode."
"This [Earth Water Spray] has a complete set of extremely efficient electrolytic separation equipment built into it. As long as it goes deep into the sea water, while the surging water power of the ocean drives power, it can also automatically absorb, filter, and process sodium chloride in the sea. Decomposes into metallic sodium with unimaginable efficiency."
"The metallic sodium decomposed by seawater power generation is used in three places. One part is fused with water in the Group A engine, consumes hydrogen, generates energy, and performs powerful water jet injection; part is fused with water in the Group B engine and is consumed. Hydrogen, producing energy for sustained sodium chloride electrolysis.”
"The last part will rise into the air with the water column in the form of small particles, contact the water for the second time, detonate the hydrogen, bring additional kinetic energy, and push the material to quickly rise into space!"
"The movement, angle, speed and thrust are controlled by high-performance computers throughout the process. As long as you are in seawater, driven by the continuous water column and hydrogen fuel explosion, let alone the earth's low-Earth orbit, what if it is further away?"
"The only material required is cheap calcium chloride. But the chlorine produced by electrolysis can completely balance the cost of calcium chloride, and you can even make some profit."
Throwing away his staff, Chen Yu faced the camera and spread his hands: "That's why I said it costs nothing to go to space."
[Fuck!]
[I don’t know how powerful it is!]
[First use seawater to generate electricity, then electrolyze metallic sodium from the water, then let the metallic sodium decompose hydrogen with water, and finally use the hydrogen as fuel to drive the engine and push the material upward... Nima! Which god researched this?]
[It’s completely feasible in theory!]
[This operation is so exciting!]
[Pan Jinlian said you are so coquettish.]
[I have calculated it with my fingers. The energy is sufficient and it is feasible!]
[After the calculation is completed, you should be able to manufacture it now.]
[Probably not, that electrolysis device is the most awesome!]
[Civil Affairs Warning...]
[Why has no one thought of it before?]
[Maybe the angle is too tricky.]
[I always feel that something is wrong, but when I deduce it, it seems to be the case... ]
"This product is produced by Huaxia Heavy Industry Company and 2441." Taking out the instruction card with the cylindrical bayonet, Chen Yu showed the product name in front of the camera: "Actually, it was originally produced more than ten or decades later. A prototype will be born.”
"But unfortunately, without that flash of inspiration, its appearance has been delayed for hundreds of years."
After saying that, Chen Yu put the card back, stretched out his hand, and pressed the start button of [Earth Spray]: "Next..."
“Let’s witness the power of imagination together!”

These two chapters are a bit difficult. It took me a long time to finish them and I was an hour late.
