Another implementation device of magnetic confinement - stellarator...... People want to imitate stars, so how big is the volume? A simple inverted figure-eight pipe is indeed small, but if you want to achieve long-term acceleration, the level of complexity will not be the same. I really don't want to talk about it.

In contrast, inertial confinement uses a laser to irradiate a nuclear fuel ball to produce ultra-high temperatures, generating a denser ion than that of magnetic confinement fusion, which can also trigger nuclear fusion, and can be achieved in a small size and light weight, but the problem has become more serious.

The speed that the rocket eventually gains depends on the energy supplied to the laser or particle beam generator, and the question of all this is back to the beginning -

Limitations of working fluid rockets.

This limitation is reflected in the fact that the final speed of the rocket will be far from meeting the needs of Tao Wu.

"If I were now a top consultant in the field of rocket engineering in the Saro civilization, how would I find a future for fusion rockets......"

It's a difficult question. At that time, Tao Wu leaned on the operating table and thought hard for a long time.

The moon is cold and biting in the dark night of 27 Earth days, but the cold can't penetrate the moon city after all, let alone the lunar mobile base.

A constant temperature of 25 degrees has been waiting for Taowu.

If you think about things with the thinking of the people of Saros, you must understand what kind of civilization Saros is.

Among the history books of civilization of the main god network, there are countless chronicles for the Sharo civilization, and one of them makes this summary in the prologue:

Sharo is a stubborn civilization.

They are born with ten feet (arms), which gives them a unique advantage in the field of coding. They completed the transformation from a primitive society to an Internet society in 1,900 years, and then it took 2,000 years to step into the interstellar age. It was also the last stubbornness of their only chance.

Because in the twenty-fifth year of the interstellar world, the Sharo civilization completely wiped out the race.

The cause of its extinction can be explained in one sentence:

Blooming too much light is tantamount to declaring war on most of the universe.

In higher civilizations there is a technology called cosmic holographic projection, and in higher civilizations there is also a technology called spiritual entity projection, these technologies can cross time and space, no matter which timeline your civilization is hidden, it is meaningless.

By the standards of the earth, it is not an exaggeration to say that the civilization that has mastered these technologies is "gods".

The Sharo civilization does not study the space technology of the interstellar age, and intends to directly study the initial stage of the holographic projection of the universe in one step, which will lead to their strong appearance and emptiness on the inside......

Of course, the strong people passing by don't mind giving the Sharo civilization a destruction package.

What does such a civilization that doesn't even have spaceships have to do with fusion rockets?

The moon god will not let Tao Wu learn the stubbornness of the Sharo civilization, let alone let him open a step in place, what the moon god said is to let Tao Wu start from the theory of the Sharo civilization and how to associate it with aerospace technology.

Ninety percent of the theories of the Sharo civilization have been used on the Internet, and what theories can the Internet inspire in the field of aerospace?

Sometimes, Tao Wuzhen feels that the universe is so big that there are no surprises. The initial stage of cosmic holographic projection is only a philosophy even on the earth, and there are very few theories for it in the first-level civilization, but Sharo is indeed only a zero-point nine-level civilization, whether it is evaluated from the perspective of developing energy or using energy, it does not exceed this range.

In this way, they used two sets of Internet systems, one as the content and the other as the analyzer, to study the primary stage of the holographic projection of the universe - the observer engine of the curvature of a specific time.

This already involves quantum mechanics at the elementary particle level, and to a certain extent, it also needs the wool film theory as a support, and further down, quantum transmission intersects with it. This is to open up research to the earth's civilization, and it is impossible to say that it has completed a breakthrough from theory to realization in 10,000 years.

In other words, the Salo civilization has never wavered in its insistence on the concept of going from the Internet to the Internet, and has simply figured out an Internet-style time machine.

Observer Engine.

Time machine.

Together, these two words are simple and easy to understand, and there is no upper limit to the force.

The more he analyzed, the more headache and anxiety he became, and Tao Wu had to admit that at this stage, there was at least one Einstein between his IQ and that of the Sharo.

Now back to the beginning of the question.

Human beings have long discovered that sixty-one discovered elementary particles and some unknown elementary particles make up the entire universe, in which the fermion series is responsible for constituting matter, and the boson series is responsible for bridging the four fundamental forces, explaining the entire universe as if it were a working machine.

When two upper quarks and one lower quark meet, and the gluons provide a strong interaction for the couple, a proton is formed.

If two lower quarks and one upper quark meet, neutrons may be formed.

Interestingly, quarks and antiquarks can exist at the same time, and if a quark and an antiquark go through a certain environment, mesons may form.

The nucleus of helium-3 is formed by the combination of two protons and one neutron under the strong force provided by the meson.

The process of helium-3 fusion goes like this: the high temperature brings three helium-3 nuclei together to form a carbon nucleus, while releasing a large amount of energy.

If you let the carbon nucleus ...... What about fission again?

This allows the helium nucleus to be reformed, which in turn re-fuses to form a carbon nucleus...... A perpetual motion machine seems to have been born.

Carbon nuclei fission, Tao Wu thought it was a joke at first.

In fact, in order to fission the carbon nucleus, the energy put in will be higher than the energy it releases, and whoever uses it is wise.

But if ......

Tao Wu opened the virtual drawing panel, drew a concept map, pointed to the concept map and said to the moon god: "After helium fusion, it will produce extremely high energy, and our conventional practice is to let these energy discharge from the valve well, form a hedge, and drive the rocket to accelerate, but these energy will disappear when it is discharged into the universe, if we use a magnetic confinement field to direct these energies to a specific location, and then accelerate the reaction product carbon nuclei to this position, use a neutron generator to bombard these carbon nuclei and shatter them into helium nuclei, Helium nuclei can undergo nuclear fusion in an energy stack outside to complete secondary fusion. ”

The advantage of quadratic fusion is that it perfectly circumvents the constraints of the Tsiolkovsky rocket equation on the rocket: mass must be thrown to obtain acceleration. So if the rocket wants to be faster, it needs to carry more fuel.

In secondary fusion, its reactants are outside the rocket and become a non-working fluid process. From Newton's second law, we can intuitively recognize the advantages of non-working fluid rockets——

At the same energy, the smaller the mass, the greater the acceleration.

Even......

Tao Wu created a new sketchpad on which he drew some simple outlines: "If we separate the third stage thruster from the satellite at the beginning, so that the rocket head of the stage carrying the satellite runs in front, the thruster falls behind, and the thruster is set to a ring, every time nuclear fusion occurs in the thruster reactor, this energy will act on the thruster for the first time, and at the same time, the energy passes through the annular structure and pushes the rocket head in front, is this considered a working fluid?" ”

"And what connects the rocket head and the thruster is the magnetic confinement field!"

Tao Wu excitedly passed the two sketches to the moon god: "We can discuss the details together, what do you think?" ”

Tao Wu thought that the moon god would compliment him, but he didn't expect to hear his unceremonious reply from the air: "Not very good." ”

This answer was like a basin of cold water poured on Tao Wu's head, and there was ice slag in it.

"Why?"

"Without the High Magnetic Restraint, your schematic diagram will have no meaning."

High Magnetic Restraint ......

Although there is no such equipment in the lunar mobile base, or even a production line to make it, it is possible to build a production line using entropy impairment. After all, even if some materials are difficult to refine, entropy impairment can be created in seconds.

Even if the entropy impairment is consumed and the same thing is done, the high magnetic restraint can indeed be manufactured at an industrial level below the first-level civilization.

The reason why the moon god shook his head and said "no" is that the level of the lunar mobile base to build this kind of restraint is expensive to ...... Ten times more than stealth satellites.

But in the end, the rocket launched today used these two sketches.
