Hand rubbing nuclear fusion live in the wilderness

Chapter 479 Manufacture of Infrared Space Telescope Completed

In the reactor building, Han Yuan dispatched a group of X-1 industrial robots to assist him in assembling a controllable nuclear fusion reactor.

When he drew the drawings before, he drew them in the order of assembly, so even if the parts are not ready yet, the number of parts produced is enough for him to assemble while waiting for new spare parts to be delivered.

Assembling the controllable nuclear fusion reactor, Won is going to do it himself, and industrial robots will assist him in handling various spare parts.

After all, compared to other technologies, controllable nuclear fusion is worthy of his own hands-on assembly as a souvenir.

Although the number of more than 8 parts sounds exaggerated, it is actually not difficult to assemble, because by this time, various intelligent mechanical devices have been assisted.

Unlike when assembling the electric propulsion-free medium engine and the Leluo triangular aircraft in the past, he really needed to screw every bolt at that time.

But now, if a nut needs to be tightened, no matter how many times it needs to be twisted, it can be assisted by the intelligent mechanical arm, and it is enough for him to participate in controlling the overall situation.

In the reactor building, Han Yuan didn't waste any time. With the assistance of the X-1 industrial robot, he directly started the assembly of the nuclear reactor.

The first thing to do is not to assemble the reactor, but to lay a layer of anti-seismic equipment.

For equipment such as a controllable nuclear fusion reactor, it is necessary to lay shock absorbing equipment at the bottom, but under normal circumstances, laying one layer is enough.

However, taking into account the existence of volcanic veins under his feet, South Korean Won directly made double shock absorption.

The bottom of the base is a layer of super-large base isolation structure. On this basis, a layer of shock-absorbing equipment is laid under the controllable nuclear fusion reactor to reduce and prevent the impact of volcanoes or earthquakes as much as possible.

After the anti-seismic equipment is laid, a layer of alloy plate is laid on it, and then the controllable nuclear fusion reactor is completed.

Unlike fission reactors, fusion reactors don't need such things as pits. If you want to compare them, a controllable nuclear fusion reactor is like a super large donut spread on the ground.

The high-temperature plasma rushes freely in the donut, controlled by powerful magnetic mirrors and magnetic ferrules, and the blank area in the center is where the heat energy is output.

In comparison, the general structure of the fission reactor looks more like a 'gas tank'. The energy generated is sent into the steam generation chamber through the loop conduit at the tank mouth, and then the water is heated and turned into steam to drive the turbine to generate electricity.

The tank, meanwhile, is surrounded by pools of reactive reactor water that cools and slows down neutrons.

But this structure does not exist in the controllable nuclear fusion reactor.

It is not to say that controllable nuclear fusion does not require cooling and heat dissipation. The cooling and heat dissipation of fusion reactors are also very critical, but in comparison, the main body of fusion reactors does not need to dissipate heat like fission reactors.

Because the most important point of the fusion reactor is to control the temperature, the precious heat will not let you lose it easily.

Of course, how to ensure that the materials of the reactor will not be damaged under the huge temperature difference of hundreds of millions of degrees is another problem, not a problem of heat dissipation.

The heat dissipation of the controllable nuclear fusion reaction is mainly concentrated on the first wall, and the method adopted is also completely different.

Traditional water cooling requires a certain volume of condensed water or other liquid media to take away the heat of the reactor to ensure its stable operation, which will occupy a considerable part of the space in the reactor building.

Not to mention the low efficiency of heat dissipation, and this is an important factor restricting the miniaturization of controllable nuclear fusion.

All dissemination of controlled fusion reactors requires other means.

The heat dissipation technology he uses is an active heat exchange technology called 'thermoelectric coupling'.

Its principle is based on thermal radiation, which uses electron transfer to transfer thermal energy.

As we all know, any object with temperature will radiate infrared rays, and the higher the temperature of the object, the higher the radiation efficiency.

Infrared radiation consumes heat energy. To sum up, using a 'thermoelectric coupling' heat exchange system to transfer and concentrate heat is a pretty good way.

Moreover, the use of electrons to transfer thermal energy can avoid waste, because the transferred electrons can generate electricity through paramagnetic spin.

It exploits the local thermal perturbation ability of spins in solids in paramagnetic materials, which converts heat into energy.

This effect, which converts the temperature difference into a voltage, is what the researchers call "paramagnon resistance thermoelectric potential."

The discovery could lead to more efficient thermal energy harvesting, for example, converting the heat from car exhaust into electricity to improve fuel efficiency, or using body heat to power smart clothing.

Of course, in reality, paramagnetic spin power generation is only a theory at present, or only exists in the laboratory for preliminary research and development.

However, using this technology, Won can convert a part of the thermal energy of the neutron radiation heat through the first wall into electrical energy, which by the way plays a cooling and cooling role.

The most important thing is that its adjustment sensitivity is much more convenient and controllable than water cooling.

After all, water cooling removes heat through pipes, and the size and number of pipes determine the cooling efficiency of water cooling.

However, the 'thermoelectric coupling' active heat exchange technology is different. By controlling the number and speed of electrons, it is completely possible to adjust the temperature at any time, thereby adjusting the power output of the controllable nuclear fusion reactor.

In the reactor building, while assembling a controllable nuclear fusion device, Won chatted with the audience in the live broadcast room, and occasionally explained relevant knowledge points.

After the first day's assembly work was completed, he returned to the workshop, put on a brainwave signal reader, and derived a complete set of manufacturing materials for launch vehicles and space shuttles from the primary aerospace application knowledge information in his mind.

After checking and modifying, Han Yuan handed over the information to the artificial intelligence Xiaoqi, who will carry out the production of launch vehicles and space shuttles.

As for the materials, except for some existing common materials, other materials won are simply exchanged with technology points.

After all, time is a bit urgent. Although there are still more than five months left in the first year, he cannot compress the time to complete the task to the limit.

That way, if something goes wrong, he can't fix it.

Therefore, the best way is to let Xiaoqi take charge of this work. It is best to manufacture the launch vehicle and space shuttle simultaneously when the assembly and commissioning of the infrared space telescope is completed.

In this way, the space telescope can be launched on time after its manufacturing and debugging are completed.

The reserved time can ensure that he will conduct another space launch to remedy the accident after the accident.

After handing over the manufacture of the launch vehicle and space shuttle to Xiaoqi, Han Yuan returned to the reactor factory to continue assembling the controllable nuclear fusion reactor.

The days passed day by day, and the parts processed by the CNC center were continuously transported by industrial robots to the reactor building, and then assembled by his hands.

More than half a month has passed, and the originally empty central area is now filled with various materials and parts.

There is also a huge semi-finished ring in the central area of ​​the square, with a diameter of more than 50 meters, which is spread on the ground, like a huge tire that has been broken from it.

Compared with the controllable nuclear fusion device in the Taishan base, the reactor in the Amazon rainforest base occupies a full three times larger area.

After it is completed, its power generation capacity will be more than tripled, and it is not uncommon for it to be increased by [-] times.

The power generation capacity of a controllable nuclear fusion reactor is related to the amount of plasma undergoing fusion reaction in the device on the one hand, and is related to the power generation device on the other hand.

If the magnetic fluid power generation and paramagnetic spin power generation are replaced with boiling water, the power generation can be reduced the least.

Because the utilization efficiency of heat energy between the two is completely different.

Although the current highest-efficiency water turbine can use more than 90.00% of kinetic energy, the efficiency of boiling water and using steam to drive the turbine to generate electricity is actually only about 40.00% to [-]%.

Because in the process of boiling water and steam transfer, a considerable part of heat energy will be lost.

But even so, for humans, boiling water is really the best way to convert heat energy into electrical energy on a large scale.

Although boiling water may not be the most efficient, considering the cost scale and availability, it is the only option.

If we want to improve the utilization efficiency of heat energy, the efficiency of boiling freon or hydrogen, helium, high-temperature lithium vapor and other gases that are close to ideal gases is much higher than that of boiling water.

If the power generation efficiency of boiling water can reach 50.00%, then the efficiency of boiling freon can reach more than 70.00%; and the utilization efficiency of heat energy of boiling high-temperature lithium steam can reach more than 80.00%.

But whether it is cost or environmental protection, it is doomed to boil freon or high-temperature lithium vapor to be unable to be used on a large scale.

Therefore, the way human civilization has always been generating electricity is actually thinking of ways to boil water.

Because this is indeed the most appropriate way.

It's just that after the establishment of this controllable nuclear fusion reactor, the method of boiling water to generate electricity will become history to a certain extent.

Whether it is magnetic fluid power generation or paramagnetic spin power generation, when applied to a controllable nuclear fusion reactor, the efficiency is far higher than boiling water.

The magnetic fluid power generation technology is that when the plasma of the magnetic fluid crosses through the magnetic field, the positive and negative particles of the plasma are separated under the action of the magnetic field and gather on two surfaces equal to the magnetic field lines. Due to the accumulation of charges, a potential difference is generated , and then export electric energy.

In fact, at present, the efficiency of magnetic fluid power generation itself is only about 30.00%, which is far less than that of boiling water.

But after it is used, the plasma gas still has a very high temperature.

The plasma gas discharged after magnetic fluid power generation can be sent to a general boiler to be burned into steam to drive a steam turbine to generate electricity.

Then form a more efficient combined cycle power generation, the total thermal efficiency can reach about 60.00% to [-]%.

It is the highest among the high-efficiency power generation technologies currently under development.

In addition, the use of plasma gas can also achieve effective desulfurization and effectively control the generation of sulfide, which is a low-pollution combined cycle power generation technology.

Of course, this desulfurization is actually based on the use of fossil fuels such as coal to heat plasma gas.

If it is applied to controllable nuclear fusion technology, the advantage of effective desulfurization is not an advantage.

After all, a controlled nuclear fusion reactor does not produce sulfur, it only produces ultra-high temperature neutron radiation.

How to use ultra-high temperature neutron radiation more efficiently is what needs to be studied in controllable nuclear fusion technology.

More than half a month passed, and a small part of the controllable nuclear fusion reactor was assembled. The audience in the live broadcast room wanted to continue watching, but Won had to stop what he was doing.

Without him, the manufacture and assembly of the infrared space telescope has been completed, and his next focus is to send this space telescope, which has stronger observation capabilities than the Webb telescope, into the L2 Lagrangian point and start working.

This is a systematic task, far more important than building a controllable fusion reactor.

Putting down his work, Han Yuan rushed to the CNC factory.

More than four months ago, the polishing, assembly and debugging of the infrared outer space telescope had been going on.

And four months later, the telescope is finally complete.

The infrared space telescope that has completed the overall assembly and debugging work is stored in the top clean room in the CNC factory.

After changing his clothes, Han Yuan entered the clean room with the filming equipment, and what he saw was a huge monster with a diameter of more than 20 meters.

The huge infrared telescope stands quietly in the clean room, with a golden primary mirror supported on a silver-white base, which looks like a sailing ship.

Eighteen beryllium-iridium alloy mirrors form a huge primary mirror. When fully deployed, the primary mirror has a diameter of more than 11 meters, which is almost twice the size of the primary mirror of the Webb Telescope and five times that of the Hubble Telescope.

The huge primary mirror allows it to see the deep space of the universe farther than the Webb telescope. In theory, this telescope can see about [-] million years after the Big Bang, that is, it can see the first time in the universe. Even the light emitted by the first stars, and even the infrared radiation emitted by the "quark-gluon plasma" formed by the hot radiation after the Big Bang.

Of course, this is only theoretical calculation data. How far you can actually see and how many details you can see will not be known until this space telescope is launched into the sky.

[It's golden, it's so beautiful. 】

[This is the same as the Webb telescope, the mirror is coated with a layer of gold, right? 】

[It's a pity not to spread pancakes with such a smooth mirror surface. 】

[Upstairs you are really a fucking talent, you use the telescope that cost hundreds of billions of dollars to spread pancakes (_)]

[Such a good mirror surface must be protected by a top-level tempered film. Don't be like Weber, and it will be smashed by a meteor when it goes up. 】

[The tempered film is also ground and polished for three months, otherwise the reflection effect will not be achieved. 】

[The polished tempered film is too smooth, so another layer of tempered film needs to be applied to protect it. 】

[Where is the matryoshka? 】
