Ruan Lin lowered his head: "Then again, wit, let's start the recent development report on Europa." ”

"At present, a sterile base on the surface has been established, and according to your guidance, the manufacturing idea of the ice drilling robot has been perfected, and then we are ready to lay an exclusive assembly line in the aseptic base and start production."

"The survey robot has collected a lot of small equipment inside the triangular building, and I can tell from the perspective of several excavation robots behind you that they are all video playback devices."

Ruan Lin turned around: "Very well, these video playback devices must be properly placed, they are carriers of memories spanning millions of years, and we will need to watch them one by one later." ”

Ruan Lin sighed, and then said, "I still need to trouble you, wit." We need to set up a couple of cranes next to the cube building, and those two spatial jump engines are so huge that you need to manage them. And my main computing power has to be used for controlled fusion technology and the engine that goes with it. ”

At present, the theory and technology of controlled nuclear fusion have been perfected, and the engine supporting it is still a problem that Ruan Lin needs to solve immediately.

Ruan Lin began to consult all human materials, and there was a concept map of a controllable nuclear fusion engine that gave Ruan Lin an idea.

The controllable fusion engine in the concept image is similar to the solid rocket engine on Earth, but its nozzle is longer and thinner, and it has been modified with an electromagnetic nozzle, and a set of cryogenic control systems and gas coolant have been added to the front.

The second half is a scaled-down tokamak: in the center is a circular vacuum chamber with magnetic coils wound inside. When energized, a huge spiral magnetic field is generated inside the tokamak, which not only confines the hydrogen plasma, but also heats it to a very high temperature for the purpose of nuclear fusion.

The final electromagnetic nozzle part is also equipped with an additional pulse device.

Ruan Lin decided that the controllable fusion engine in this concept map was the most likely, and began to refine it.

His consciousness returned to the quantum computer, where he began to make countless simulations and further refinements.

Ruan Lin's current state is like the proverb that 'he doesn't listen to what is going on outside the window, and only reads the books of the sages.'

In the first improvement of the simulation, Ruan Lin thickened the magnetic inductance coil in the vacuum chamber.

In the second simulation, he modified the thruster of a controlled fusion engine to a relative thruster.

Nguyen Lin's communication with the WIT is also underway, and Nguyen Lin plans to ask the WIT to build a base dedicated to a controlled nuclear fusion engine, which will have an initial power of 70 megawatt hours and collect the bottom sea water ejected by the "active volcano" on Europa's surface. These are the first steps in initiating a nuclear fusion reaction.

The operation of the base was quickly completed by WIT, and Nguyen Lin named the base "The Sun".

It is so named because when it was on Earth, people called controlled nuclear fusion "artificial little sun", and the sun relied on the core to continuously carry out nuclear fusion and release huge amounts of energy. Controlled nuclear fusion is a copy-paste of the sun.

According to the expression of the mass-energy equation, the mass-energy conversion rate of nuclear fusion can reach 0.7%. More intuitively, with the same 1 kg of raw material, the mass-energy conversion rate of controllable nuclear fusion is 53.9 million times that of firewood, 30.45 million times that of raw coal, and 14.91 million times that of oil.

Nguyen Lam can't wait to carry out experiments on a controlled nuclear fusion engine inside the "Sun" base...

Nearly a month has passed since Ruan Lin searched for the constituent materials in the Titan's warehouse until the first main engine was built.

Unbeknownst to Ruan, within a month, several ice-drilling robots had already traversed 25 kilometers of ice and reached the ocean below Europa. A number of refining bases have been established on the surface. That's why the deuterium and tritium used in his subsequent experiments were endless.

Nguyen Lam began the first formal physical experiment, and the engine reached 4 meters wide at its widest point, 3 meters long and 2 meters high. Ruan Lin decided to use the controllable nuclear fusion engine on the Titan first, and this time the engine volume was also set taking into account the size of the Titan.

The first experiment turned out to be a failure, and in the first second of start-up, about 64 megawatt-hours of electricity were consumed, but this reaction produced about 500 megawatt-hours, and the Earth can only consume 7,000 to 9,000 megawatt-hours of electricity in a day. This even feeds back the power supply to all the devices on Europa.

The reaction lasted only 173 seconds, far from meeting the criteria for forming a sustained fusion reaction.

Ruan Lin smiled: "Failure is the mother of success, this failure is very normal, it is expected." ”

Ruan Lin then encountered problems such as the failure of high-energy neutrons to be fully released.

"This time it's 615 experiments, I don't know how far away from success, but it's a shame to give up."

At this time, five months had passed since the completion of the "Sun" base. Ruan Lin didn't know how the construction project outside was developing, and all his thoughts were already on it.

Ruan Lin pressed the start button, and the nuclear fusion reaction began again. He stared intently at the real-time simulation of the interior on the display.

The fusion reactor inside the engine began to run at high speed, heating the gas streams of deuterium and tritium fuel, which gradually turned into high-temperature plasma.

Next, the magnetic binding force of the reactor exerts pressure on the plasma, which successfully produces a nuclear fusion reaction.

This process lasted 492 seconds, successfully meeting the reaction time standard.

Next, it was a crucial step to frequent failures, and Ruan Lin couldn't help but clench his palms at this time.

In the real-time simulation, the resulting plasma is confined by a magnetic nozzle and gushes out backwards! The nozzle gains a reaction force and moves towards the inside of the thruster.

If the controlled fusion engine is already installed on the Titan at this time, then the thrust is transferred to the Titan in a buffered manner, and the blast doors behind the engine are opened, and the internal pulse device is fed into the combustion chamber. The rear blast door closes, followed by the magnetic nozzle closes, driving the internal pulse device to move outward.

And that's the end.

The problem that has been bothering Ruan Lin has finally been solved! This is also a problem that has plagued mankind for more than a hundred years, but at the moment it has been solved by only one human being. In other words, the combination of quantum computers and humans is complete.

Ruan Lin now began to giggle as if he were an ape-man who knew how to use tools for the first time.

"All kinds of whimsical projects on the planet, the efforts of countless scientists. It didn't work out for more than a hundred years. I have finally solved the problem of the century on behalf of mankind. Earthscientists who have spent their lives working on controllable nuclear fusion engines, you can see them here.

We humans finally have the ability to step out of our own star system.

Project Orion, Project Daedalus, Project Icarus...

You are all bold ideas that you came up with when your technology was immature. It was also the starting point of humanity's desire to fly out of the solar system. ”

"The next step is to assemble the engine onto the Titan for speed testing."
