"Its name is...
"The Earth Spray!"
【？？】
【？？？】
[What kind of waterspout is this?!]
[The name of a tiger and a wolf.]
[Why don't you call it Earth Spray?]
[Are you kidding me?]
【??】
[Just by listening to the name, I know why the scientific community can't make it.]
[As expected of you.]
[As expected of you. + 1]
[Everyone rise!
Send the old driver off!]
"That's right. It's called the Earth Spray."
Stepping aside, Chen Yu allowed the camera to capture a panoramic view of the blue cylinder. "It also has a more appropriate name — Mother Ocean's Tide.
"Everyone must be confused as to why this product has such a name. However, once I explain its principle, everyone will understand.
"As we all know, the cost of launching a rocket into space is very high.
With current standards, it costs US $20,000 to lift one kilogram of material into space.
If each person lifts 50 kilograms, it will cost US $1 million.
If it were a heavyweight astronaut like Han Hong, even America wouldn't be able to afford it for long.
"However, if we replace it with a space elevator, the cost will plummet.
After some calculations, it will only cost US $190 to lift one kilogram of material into space.
That's a hundred-fold difference!
Even ordinary people like us who want to travel in space can afford the tickets.
Hence, you can imagine the various governments' yearning for a space elevator. "
"Alright." Clapping his hands, Chen Yu pointed at the Earth Spray and said, "It's its turn.
If we use this product to go into space, how much will it cost? "
"... It's free."
As soon as Chen Yu finished speaking, let alone the audience, even the professors inside the castle nearly bit their tongues.
"Yes, it's free."
Emphasizing, Chen Yu said, "Not only is it free, but it can also make money."
"Because it uses water to spray the material into space.
Meanwhile, water is endless in Earth's oceans and can be reused.
Hence, it is also known as Mother Ocean's Tide.
This is a gift from nature. "
[I'm laughing.]
[Is he finally going to start a pyramid scheme?]
[You can play it for a year without spending a single cent on the equipment.]
[Hello, everyone. My name is Zaza.]
[Is it really free?
You're giving me money to go into space?]
[UP, you're talking about the low cost, right?
It's impossible to not spend a single cent.]
[That's utter nonsense!
Using water to spray matter into space?
Do you think this is the fountain on Europa?]
[Wishful thinking.
Not to mention moving matter, just spraying water tens of thousands of kilometers into space is enough energy for a rocket to fire a thousand times.]
[Space Fountain?
This is pseudoscience …]
[It's not that I don't trust the host, but it doesn't make sense in theory.]
[Don't pretend to understand when you don't, okay?
Are you guys better than the host?]
[It's not a matter of being awesome or not. No matter how awesome you are, you can't go against basic physics …]
Raising his wrist, Chen Yu took a look at the bullet comments floating around him. Shrugging, he said, "I knew most people wouldn't believe me.
Now, I will introduce the principle of this product in detail so that everyone can understand what it means to create a world with your imagination. "
As he finished speaking, he summoned Hermione and snatched the staff from her hand. He drew a diagram in the air while explaining, "First of all, we need to know the most basic chemical principle.
Water, chemical formula H2O, is the simplest hydrogen-oxygen compound.
A colorless, odorless, and odorless liquid. Under standard atmospheric pressure, the freezing point is 0C, and the boiling point is 100C.
The density is the highest at 4C. "
"Water contains hydrogen, and hydrogen is a fuel.
When mixed with oxygen, it will explode upon contact with fire.
Nowadays, all rockets use hydrogen and oxygen as fuel.
"In that case, a very interesting point will appear here!
Why don't we break down the hydrogen in water? "
After saying so, Chen Yu drew one formula after another in the air. Then, under the dumbfounded gaze of his 20 million viewers, he spoke with confidence and composure.
"There are many ways to break down water, and all of them are very simple.
For example, electrolysis. Two hours?
Two hours of electricity?
↑ + o?
↑ can be used to break down hydrogen and oxygen.
However, according to this formula, the chemical energy stored in the product is higher than that of the reactant.
According to the principle of conservation of energy, it is impossible to have a catalyst that can directly break down water into hydrogen and oxygen while ensuring that the amount of the catalyst itself remains the same.
"In layman's terms, the investment is greater than the expenditure.
It is unrealistic.
"Aside from electrolysis, there are several other methods of breaking down hydrogen that require physical contact.
For example, metallic sodium (Na), metallic aluminum (Fe), and metallic aluminum (Fe).
"Their formulas are: 2na + 2h?
O — 2 naoh + h? "
“2al+6h?
O Heating 2al (OH) 3 + 3h?
↑. "
“3fe+4h?
O (g) High temperature fe304 + 4h?
↑. "
After writing the three sets of formulas in the air using particles, Chen Yu pointed at the first formula and said, "See?
The latter two, aluminum and iron, require energy to break down into hydrogen with water.
The only exception is the expensive metallic sodium!
As long as it comes into contact with water, it can be broken down into hydrogen!
"Hydrogen!
It's fuel! "
Lowering his staff, Chen Yu pointed at the distant blue ocean under the white fog and said, "There is an infinite amount of sodium in the ocean.
All we need to do is extract it and fuse it with water. Isn't that equivalent to endless fuel? "
Without giving the audience any time to think or refute, Chen Yu continued, "In the modern industry, most of the methods used to obtain metallic sodium are the Adams method. In other words, calcium chloride is added to a sodium chloride (table salt) solution and electrolyzed under a high temperature of 500 ° C and a voltage of 6 V.
Metallic sodium is produced at the cathode, and chlorine is produced at the anode.
"Meanwhile, the Earth Spray is equipped with an extremely efficient full set of electrolysis separation equipment. So long as the Earth Spray enters the seawater, it can automatically absorb, filter, and process the sodium chloride in the sea, breaking it down into metallic sodium.
"The metallic sodium produced will be divided into three parts. One part will be fused with water in Group A's engine, consuming hydrogen to generate energy, and launching a powerful water jet. The other part will be fused with water in Group B's engine, consuming hydrogen to generate energy, and carrying out continuous sodium chloride electrolysis.
"The final part will be lifted into the air along with the water jet in the form of small particles. When the particles come into contact with the water for a second time, the hydrogen will be detonated, generating additional kinetic energy, and propelling the material into space rapidly!
"The entire process will be controlled by a high-performance computer.
So long as the Earth Spray is submerged in seawater, under the continuous water jet's propulsion and hydrogen fuel explosion, let alone Earth's low-Earth orbit, so what?
"The only material required for this process is the cheap calcium chloride.
However, the chlorine produced from the electrolysis can easily cover the cost of the calcium chloride. We might even make a profit. "
Tossing away the staff, Chen Yu faced the camera and shrugged. "This is why I said going into space is free."
[Crap!]
[I don't understand, but it sounds awesome!]
[Electrolyzing metallic sodium from the sea, then letting the metallic sodium and water split into hydrogen. Finally, using the hydrogen as fuel to drive the engine and propel the material into space... Crap!
Which deity researched this?]
[It's completely feasible in theory!]
[This operation is too cool!]
[Pan Jinlian says you're really cool.]
[I just did the calculations. There's an abundance of energy. It's feasible!]
[Same calculation completed. Many countries now have the ability to manufacture such a device.]
[It shouldn't be possible. It's very difficult to manufacture that electrolysis device at present.]
[But it's definitely faster than a space elevator!]
[Why hasn't anyone thought of this before?]
[The angle is too tricky. Maybe.]
[I keep getting the feeling that something isn't right, but that seems to be the case after some deduction...]
"This product was produced by the China Heavy Industry Company in 2441."
Taking out the cylindrical bayonet's description card, Chen Yu showed the product's name to the camera and said, "Actually, the prototype could've been born a decade or several decades later.
"Unfortunately, without that flash of inspiration, its appearance has been delayed by several hundred years."
After saying so, Chen Yu put away the card, reached out, and activated the Earth Spray. "Next...
"Let's witness the power of imagination together!"
