Nuclear fusion encompasses a variety of reactions.

Take, for example, the fusion reaction of hydrogen to helium-4.

It contains deuterium + deuterium fusion, deuterium + deuterium fusion, deuterium + deuterium fusion, deuterium + tritium fusion, the above reactions will generate a certain amount of helium-3, and then deuterium + helium triple fusion, helium-3 + helium triple fusion, and finally end the reaction with the formation of helium-4.

Helium-4 can also continue the fusion reaction.

For example, helium 4 + helium 4 produces beryllium 8, and then beryllium 8 fuses with other helium 4 to form carbon 12, and part of carbon 12 and part helium 4 fusion produces oxygen 16.

Among them, as long as the density of the plasma increases, the reaction temperature of helium-4 is 100 million K.

However, the reaction of carbon and oxygen requires more than 800 million K to produce magnesium, silicon, phosphorus, sulfur and other elements.

After 3.5 billion K, the fusion reaction of magnesium + silicon will be turned on to produce sulfur, argon, calcium, titanium, chromium, iron, and nickel.

After the iron element, the fusion reaction stops and can no longer be fused into heavier elements such as gold and silver.

Because the aggregation produces this part of the element, it needs to absorb energy, not release it.

Therefore, heavy elements with a mass greater than iron are generally synthesized by the forcible pairing of super-large energies.

For example, supernova explosions, or iron elements are slowly formed by capturing neutrons inside stars, but the latter is extremely inefficient, not even one trillionth of the efficiency of supernova explosions in synthesizing heavy elements.

Of course, the fuel in the Type A mecha is helium-three, and the fusion reaction is also dominated by helium-three, and the synthesis of helium-4 stops.

But the amount of energy released is also large enough to be used as a source of engine power, far beyond any means on Earth today.

As a result, the A-type mech can fly at Mach 20 in the atmosphere, and in outer space, it can soar above Mach 100 due to the lack of air resistance.

Even, as long as the fuel is sufficient, with all the fuel and energy supplied to the power system, the mech can accelerate to a maximum speed of 2% of the speed of light in outer space, which is about 6,000 km/s, more than Mach 17,000.

Of course, this is a case where only acceleration is considered, and no deceleration is considered, and all fuel is used up.

It's okay for those unmanned scientific research vehicles that don't need to slow down, but for manned vehicles, it's just sending people to death.

But for the Type A mech, it is unrealistic to consider the functions of the life support system and other systems, so it is unrealistic to use all the fuel to accelerate.

Moreover, since the Type A mech is always just a lightweight battle mech, not the kind of aircraft that is specifically used for navigation, its speed is certainly not as fast as those that can achieve interstellar navigation.

However, in the field of nuclear fusion power engines, there is a limit to the speed of the aircraft, regardless of the purpose of the aircraft.

One is the dry mass ratio (the weight of the aircraft when it is fully loaded with fuel/the remaining mass of the aircraft after the fuel is exhausted), and the second is the mass-energy conversion rate of nuclear fusion.

For example, if you want to accelerate the speed of the aircraft to 10% of the speed of light, under the ideal state, according to the speed of 9% of the speed of light, the dry-mass ratio should reach more than 3 according to the Aclay formula, which is not much, and it is completely within the acceptable range.

Among them, the A-type nuclear fusion mecha has a dry mass ratio of only 1.25, so it can only accelerate to 2% of the speed of light.

Further up, if you want to get to 30% of the speed of light, the dry-mass ratio will have to run above 30.

As for accelerating to a sub-light level such as 99%, it will be even more ridiculous, and the dry-mass ratio will probably swell to 6 trillion.

This means that in order to accelerate the aircraft to 99% of the speed of light, assuming that the mass of the aircraft itself is 1 ton, then it must carry 6 trillion tons of fuel.

In other words, it would take 6.1 million tons of nuclear fuel to accelerate 1 gram of payload to 99% of the speed of light.

In such a situation, it is absolutely impossible to travel at the speed of light or sub-light by nuclear fusion, and engineering technology does not allow it.

However, what speed of light, sub-light, that is too far away for earthlings.

Not even mentioning 2% of the speed of light, divided by 100, only 2/10,000th of the speed of light is needed to make it possible to navigate between the Earth and the Moon without obstacles.

Don't think that this speed is much worse than the speed of light, but it is still 60km/s, far exceeding the three cosmic speeds.

At this speed, even the 400,000 km apogee from the Earth to the Moon takes less than two hours.

Of course, in reality, it is necessary to consider the time of acceleration and deceleration, and the size of the acceleration, the real time will be longer than two hours, but not much.

Due to the life support system within the mecha, there is a special deep-sea liquid that can allow the wearer to withstand an acceleration of 30G.

According to this acceleration, the acceleration from zero to 60km/s only takes 204 seconds, and if you count the deceleration, it is only doubled, with a total of 408 seconds more, but in just six or seven minutes, plus the normal sailing time, the overall time is still less than two hours.

In less than two hours, you can go from the earth to the moon, this speed, isn't it slow?

"With this thing, it means that going to the moon is not much different from going back to Ningcheng's hometown and going to Shanghai, Shenzhen and other cities."

For a while, Yuan Ze became excited.

"We have to find a place to set up the production line, and then collect raw materials to produce mechas, and when the mecha is produced, find a few of our own people to wear and try.

Let's see if we can fly directly to the moon.

If you could......

Gan! Then who the hell is still playing with you on the earth, buddy is going straight to the moon! ”

Thinking of this, Yuan Ze's whole body boiled.

But then, at the thought of something, he suddenly frowned again.

"I almost forgot that among the raw materials for the production of mechas, there is such a thing as helium-three, and it takes 500 kilograms of helium-three to produce a mecha, and it is estimated that helium-three is used as fusion fuel.

The point is, helium-3, I remember in the earth's nature, the content seems to be very small, right?

But there are a lot of helium-3 on the moon......"

On Earth, there are more helium-four with two neutrons + two protons, which is commonly known as helium.

However, its isotope helium-3 is very rare in the earth's nature.

There is artificial helium-three, so that super-heavy hydrogen, that is, tritium, can form helium-three after β decay.

Speaking of which, tritium is also one of the fuels for nuclear fusion, but it is only the fuel for the first generation of nuclear fusion, deuterium + tritium nuclear fusion, and a large number of high-energy neutrons will be produced during fusion, which is not very safe.

On the contrary, helium triple fusion is safer.

Whether it is the deuterium + helium triple fusion of the second point or the third generation of helium triple + helium triple fusion, they are relatively clean and safe.

However, although tritium decay can produce helium-three, the problem is that the yield is very low, and the half-life of tritium is 12.5 years, which is short compared to other substances, but not short for humans.

Especially Yuan Ze, he can't wait for more than ten years.

And tritium, like helium-3, is very rare in the earth's nature, and if you want to make tritium in large quantities, you have to use artificial methods, such as using neutrons from fission reactors to bombard lithium-6 compounds, which is very troublesome.

"I've got to figure out how to get some helium......

Moreover, since the plug-ins have been given to the mecha production line, there is no reason why I will be asked to produce a bunch of mechs without fuel, right?

The protagonist's aura, it's up to you, please give it up! ”

In addition to the fusion energy system and power system, the A-type mecha also has a powerful armed system.

First of all, the mecha is extremely stealth, and can absorb electromagnetic waves in the radar band, which cannot be detected by the radar system of the current era.

The second is a powerful reconnaissance system, which can image the ground in outer space and lock on to the target at an ultra-long distance when the weather is good and there is no cloud covering.

Then, in terms of weapons, there are electromagnetic guns, high-energy lasers, and high-energy ion beams.

Among them, the electromagnetic cannon is actually an enhanced version of the Gauss gun that Yuan Ze obtained before, but the integration is more dense and elaborate than the Gauss gun, and after a pair of mecha leaves the factory, it has 30 electromagnetic guns.

When the mecha is in the atmosphere, flying at a maximum speed of Mach 12, the rate of fire of the electromagnetic gun can reach more than Mach 60.

Moreover, due to the ingenious design of the ammunition structure of the electromagnetic cannon and the low wind resistance, firing the gun from a distance of 50 kilometers can reach and destroy the target in three seconds.

At present, there is basically no air defense system on the earth that can protect against the surprise attack of electromagnetic guns, not even aircraft carriers.

Of course, it will definitely not sink the aircraft carrier, but if the 30 electromagnetic cannons of a pair of mechs all hit the aircraft carrier and destroy its hangar and command center, it should not be a big problem.

As for fighting fighters, they can't even see the shadow of the mecha, so what to fight?

The technological gap is too great, and in the atmosphere, even the most advanced sixth-generation fighters on the earth can only be hit by the target, and they will not even have a chance to fight back.

High-energy lasers and high-energy ion beams are suitable for operations in outer space, such as destroying satellites and space stations.

It can be said that only a few dozen A-type mechs loaded with nuclear fuel and weapons arsenals are needed, and in the aerospace field, all the countries of the planet combined, are not enough to fight.

Once the attack begins, take out the satellite first, so that the enemy becomes blind and targeted.

Then he wandered the Kármán line in outer space and found a fighter jet taking off and destroying one.

Or, go directly to the air base and the place where the aircraft carrier is located to make trouble, and run away after the fight, but the enemy can't even touch the shadow of the mecha.

Of course, Yuan Ze is a peace-loving person, as long as no one takes the initiative to provoke him, he will not displease people to destroy peace.

If there is a plug-in task, it is not listed.

"This production line can't be produced in China!

Moreover, there are a lot of black technologies in the A-type mecha, and the technology covered by the miniaturized controllable nuclear fusion alone is enough to subvert the existing world pattern.

Then go to a foreign country to find a place, build a secret base of my own, and quietly find some scientific researchers to sign confidentiality agreements and loyalty agreements, and study the black technology in the mecha......

But where to choose? ”

While thinking about it, Yuan Ze dialed Fang Yuebin's phone and first inquired about the progress of the liquidation plan.

After learning that everything was progressing steadily, he instructed Fang Yuebin to purchase land overseas.

Fang Yuebin asked: "Mr. Yuan, which region do you really like?" ”

Yuan Ze thought for a while and said: "The northern hemisphere is definitely not good, the Pacific Ocean is also the doorstep of Lao Mei, forget about Africa, well, it is best to be in Southeast Asia and Australia, I remember that there are many Chinese in Australia who are buying land, and it is permanent, if you can, you start from this aspect." ”

Fang Yuebin responded: "Okay, I understand!" However, Mr. Yuan, this matter may take a little time, and it cannot be done in three or five days. ”

"Give you two months."

"Two months is enough! Just wait for my good news. ”

……

A few days after May Day.

In addition to being with the canaries, Yuan Ze also set up two new projects in the Blue Whale Pharmaceutical Company.

Breast enlargement spirit and hair growth spirit.

These two items are derived from the two treasures obtained before, 1 breast enhancement capsule printer, and 1 powerful hair growth pill.

In addition, it is worth mentioning that as the SC100 chip was assembled to form a data center, Wang Jingshan also used the quantum computing in it to reverse extrapolate and analyze the K-type drug molecules inside Zhuyanling.

Not surprisingly, the optimal synthesis step for the K-type drug molecule was easily obtained.

But unfortunately, with the existing science and technology of the Blue Whale Company, it cannot meet the synthetic standards of the anti-aging cream printer, and can only be produced on a small scale in the laboratory, and the cost is scary.

Hearing the news from Wang Jingshan, Yuan Ze was a little regretful, but not very surprised.

Because, he found out before that when the plug-in gives the printer and production line, instead of giving the technical information, it basically means that with the modern manufacturing level of the earth, it is impossible to mass-produce the product, and it can only be done through the black technology printer and production line given by the plug-in.

It's not just anti-aging creams, photovoltaic cells, and A-type mechas, it's all the same.

Therefore, Zhuyanling and the newly established breast enhancement spirit project can only take the high-end consumption route.

On the contrary, the fat loss spirit, the sleep spirit and the hair growth spirit can take the route of mass consumption.

……

May 10th.

In the evening, Yuan Zezheng was playing games on the sofa with Li Youge and Yu Kefei.

At this time, after a day's work, Lin Aoyu, who was extremely tired, dragged his delicate body to open the door and returned home.

glanced at the sofa in the living room, you and me, Li Youge, Yu Kefei and Yuan Ze, who were both leisurely and comfortable, frowned slightly.

Originally, what others do and how they live is someone else's business, as long as she doesn't break the law, she Lin Aoyu can't care about it.

But seeing that Li Youge and Concubine Yu Ke, since they got along with Yuan Ze, a scumbag, they have become lazy and lazy, which made Lin Aoyu inexplicably a little angry.

But if there is anything wrong with them, it is not necessarily, after all, their current living state is not the living state that countless girls dream of in reality?

As long as they don't talk to Yuan Ze about marriage, almost what they want, Yuan Ze will buy them anything.

It was a very nourishing day.

Even though he was angry in his heart, Lin Aoyu actually couldn't find a reason to be angry.

If you insist on forcibly pulling a reason to come out, it is because they took shortcuts and got it for nothing, which makes Lin Aoyu, who has always been dutiful, honest, conscientious, hard-working and upright, feel unfair, so he is angry!

No, to be precise, it should be jealousy.
