"Its name is ......"

"Earth squirts!"

【？？】

【？？？】

【God squirts water!】

[The name of the tiger wolf. 】

[It's better to call it the earth.] 】

[Are you kidding?]

【?? 】

[Listening to the name, I know why the scientific community can't make it.] 】

[It's you. 】

[It's your +1.] 】

[All stand up!See off the old driver!]

"That's right, it's called Earth Spray. Chen Yu turned to the side and let the camera take a panoramic view of the blue cylinder: "It also has a more appropriate title - the tide of Mother Ocean." ”

"People can't understand why this product has the same name, but when I understand how it works, everyone will understand. ”

"It is well known that the cost of rocket lift-off is high. By today's standards, it would cost $20,000 to lift off 1 kilogram of material. Fifty kilograms for one person costs $1 million. If it is a heavyweight astronaut like Han Hong, even if he is rich and wealthy, he will not be able to bear it for long. ”

"But if you change to a space elevator, the cost will plummet. It has been calculated that 1 kilogram of material will cost only $190 to ascend into space. A hundredfold difference! Even if we ordinary people want to travel around space, we can afford to spend tickets. Therefore, it is conceivable that the officials yearn for the sky elevator. ”

"Alright. Chen Yu clapped his hands, pointed to the [Earth Spray] and said, "It's its turn." How much would it cost to go to space with this product?"

“...... Don't want money. ”

As soon as these words fell, not to mention the audience, even the professors in the castle almost bit their tongues.

"Yes, no money. ”

Chen Yu emphasized: "Not only do you not need money, but you can also earn money. ”

"Because it's water, spraying the carrier into space. Water, on the other hand, is endless in the Earth's oceans and can be reused. That's why it's also called the tide of Mother Ocean. It's a gift from nature. ”

[Ye smiled.] 】

[Are you finally going to engage in MLM?]

[Click to play for a year, and the equipment does not cost a penny.] 】

[Hello everyone, my name is Zaza Ash. 】

[Does it really cost nothing? Give me back the money in space?]

[What the UP master said should be that the cost is very low, right? 】

[Utter nonsense!Spraying matter into space with water?Think it's Europa's fountain last time?]

[Speculation.] Not to mention propelling matter, simply spraying water into space tens of thousands of kilometers is enough energy for a rocket to use a thousand times. 】

[Space fountain? This is pseudoscience......

[It's not that I don't trust the anchor, but it doesn't make sense at all in theory.] 】

[Don't know how to pretend to understand, OK?

[It's not a question of whether it's a cow or not, no matter how good it is, it can't violate the basic physics common sense......]

Raising his wrist and glancing at the barrage of speculation, Chen Yu shrugged: "I know that most people don't believe it." So now, I will introduce the principle of this product in detail, so that you can understand what it means to create the world with brain holes. ”

As the words fell, Hermione was summoned, snatched the staff from her hand, and drew a picture in the air as she spoke, "First of all, we need to know a basic chemical principle. Water, with the chemical formula H2O, is the simplest hydroxide compound. A colorless, tasteless and odorless liquid, at standard atmospheric pressure, freezing point 0C, boiling point 100C. The density is highest at 4C. ”

"Water contains hydrogen, and hydrogen is a fuel. When mixed with oxygen, it explodes when it encounters fire. Today, all rockets also run on oxy-hydrogen fuel. ”

"So there's an interesting point here: Why not break down the hydrogen out of the water?"

Saying that, Chen Yu was in the air, drawing formulas one after another with dragons flying and phoenixes, and talking eloquently in the stunned eyes of 20 million viewers.

"There are many ways to break it down, and it's very simple. For example, in the electrolysis method, hydrogen and oxygen can be decomposed by energizing 2h?↑+o?↑ at 2h?o. However, according to this formula, it can be concluded that the chemical energy stored in the product is higher than that of the reactant. According to the principle of conservation of energy, there can be no catalyst that can directly split water into hydrogen and oxygen without keeping the amount of the catalyst itself unchanged. ”

"To put it mildly, the investment is greater than the expenditure. Unrealistic. ”

"In addition to electrolysis, several other methods of decomposing hydrogen require material contact. For example, sodium metal (Na), metal aluminum (Al), metal iron (Fe). ”

Their formulas are: 2Na+2H?O—2NaOH+H?. ”

"2al+6h?o, heating 2al(oh)3+3h?↑. ”

"3Fe + 4H?O(G) High temperature Fe304+4H?↑. ”

Writing the three sets of formulas in the air with particles, Chen Yu pointed to the first formula and said, "See? The aluminum and iron of the latter two need energy output if they want to be decomposed into hydrogen with water." Only the expensive metal sodium can decompose hydrogen as long as it comes into contact with water!"

"Hydrogen is fuel!"

Putting down the staff, Chen Yuyao pointed to the blue ocean under the white mist in the distance: "In the sea, there is infinite sodium." We just need to extract them and fuse them with water, isn't that the equivalent of endless fuel?"

Without giving the audience room to think and refute, Chen Yu continued: "In modern industry, most of the acquisition of sodium metal is the Dangsi method, that is, calcium chloride is added to the sodium chloride (table salt) solution, and electrolysis is used to generate sodium metal at a high temperature of 500C and a voltage of 6V. Among them, sodium metal is generated at the cathode and chlorine is generated at the anode. ”

"As long as it penetrates deep into the seawater, it can automatically absorb, filter, and process sodium chloride in the sea and decompose it into sodium metal. ”

"The decomposed sodium metal is used in three places, one part is fused with water in the group A engine to consume hydrogen and produce energy for high-power water column injection, and the other part is fused with water in the group B engine to consume hydrogen and produce energy for continuous sodium chloride electrolysis. ”

"The last part will be in the form of small particles that will rise into the air with the water column and come into contact with the water for the second time, detonating the hydrogen, bringing additional kinetic energy and pushing the matter to quickly rise into space!"

"Movement, angle, speed and thrust are controlled by a high-performance computer. As long as you are in the middle of the sea, under the continuous push of the water column and the explosion of hydrogen fuel, let alone the low earth orbit of the earth, what if it is a little farther away?"

"All we need is cheap calcium chloride. However, the chlorine gas electrolyzed can completely flatten the cost of calcium chloride, and even some of them can be earned. ”

Throwing away the staff, Chen Yu faced the camera and spread his hands: "What I said about not needing money to go to space is based on this." ”

【it!】

[I don't know how to feel it!]

[Electrolysis of sodium metal from the sea, then splitting hydrogen between sodium metal and water, and finally using hydrogen as fuel to drive the engine and push the material up...... Nima: Which god researched this?]

[Theoretically possible!]

[This wave of operations is too sassy!]

[Pan Jinlian said that you are really sassy. 】

[I have just calculated, the energy is rich, it is feasible!]

[After the calculation, many large countries now have the ability to manufacture. 】

[Probably not, that electrolyzer is currently difficult to get out.] 】

[But it's definitely faster than a space elevator!]

[Why hasn't anyone thought about it before?]

[The angle is too tricky, maybe. 】

[I always feel that something is wrong, but it seems to be the same thing when I deduce it......]

"This product was produced by Huaxia Heavy Industry Company and 2441. Taking out the instruction card of the cylindrical bayonet, Chen Yu displayed the name of the product in front of the camera: "In fact, it could have been born into a prototype in a dozen or decades." ”

But unfortunately, the lack of that flash of inspiration has delayed its appearance for hundreds of years. ”

After that, Chen Yu put back the card, stretched out his hand, and pressed the start button of [Earth Water Spray]: "Next......"

"Let's witness the power of brain holes!"
