Technology and life: starting with solar cars

Chapter 12 Uranium-235 Nuclear Fission Engine
Facing the victory of Yunfan Technology, Mr. Wang nodded in satisfaction, and at the same time was a little shocked by the performance of Liuyun Automobile.

From the very beginning, Wang Lao noticed the abnormality of Yunfan Technology's participating cars.

The first is the temperature of the exhaust pipe. The flame of the exhaust pipe is thick red. This kind of flame must be 1000 degrees, which has exceeded the maximum temperature of existing cars.Moreover, the exhaust pipe of the car does not look red at such a high temperature, which is really abnormal.

Then there is the sound of the car engine is not normal.A normal engine has that kind of cylinder knocking sound, which can be distinguished at a glance, but the car engine of Yunfan Technology can't hear any sound at all.This shows that Yunfan Technology's car does not generate power by knocking on the cylinder block. He speculates that it may be fueled by high-energy substances. As for the structure of the engine, he cannot guess.

Finally, the acceleration of the car is too fast. It only takes 0.5 seconds to accelerate from 20 kilometers to [-] kilometers. No car can reach this speed.If it weren't for the restriction of the gymnasium's walls, Liu Yun's car should complete a lap faster than it does now, and it is estimated that it can complete a lap in [-] seconds.

Wang Lao stood in front of the car curiously, knocking and touching the car to identify the material of the car.It's a pity that the feeling of the car body doesn't match the materials in his memory, which confuses him.

He said embarrassedly: "Liu Yun, can I study your car?"

"Of course not." Liu Yun flatly refused. It was impossible for him to lend the car without a valid reason.

"Hey, let me tell you the truth. In fact, I am a researcher in the Han Dynasty, and I am specialized in the field of automobile research. Otherwise, I would not have the cheek to ask you to study the automobile. You can rest assured that I will return it to you if you need it. Dismantling will also be subject to your consent." Wang Lao sighed.

It turned out that this was the case, Liu Yun suddenly realized, no wonder so many people gave Wang Lao face, it turned out that Wang Lao is a real researcher, with a high reputation for his superb technology.

That being the case, let's study it for Mr. Wang.

He just didn't know how much time the rocket car had left, so Liu Yun said silently: "System, check the remaining time."

[Ding, the remaining time is 20 minutes and 59 seconds. 】

There are only 21 minutes left. Excluding the time to drive to the research institute, it is estimated that the remaining 10 minutes will be good, but it is a pity.

He said to Mr. Wang: "Mr. Wang, you can study it, but there is bad news to tell you that the engine is estimated to be damaged in 20 minutes due to excessive load."

When Mr. Wang heard this, he was very anxious, and he dragged Liu Yun straight to the research institute.

After arriving at the research institute, I couldn't wait to open the engine compartment, and what I saw was a very huge engine, which took up more than half of the engine compartment.

Mr. Wang touched the surface of the engine, and found that the temperature was not too high, only fifty or sixty degrees. Later, he picked up a flamethrower and blazed at the engine.

1000 degrees, the engine walls did not turn red.

At 2000 degrees, there is still no change in the engine wall.

When it reached 3000 degrees, Mr. Wang was afraid that the engine would burn out, so he asked Liu Yun: "Can you increase the temperature, I'm afraid it will be damaged if the temperature is too high."

After getting Liu Yun's consent, Mr. Wang took out a high-temperature device-plasma arc.

The plasma arc emits extremely high temperatures close to the engine, but the engine still does not respond.

Suddenly, the car beeped.

"Warning, warning, the engine is under an unknown attack, and the body temperature rises rapidly. When the temperature reaches 1 degrees, the engine will start the self-destruction procedure. In order to avoid the damage caused by the self-destruction procedure, please evacuate the people nearby to 10 Kilometers away, or you may be hurt by the shock wave of the explosion."

Then the car's engine blew a high-pitched siren.

Mr. Wang was startled, and stopped the heating in his hands based on the principle of safety first, and asked Liu Yun anxiously: "What kind of material is in this engine, how could it explode?"

"It's uranium-235 in it."

"Why didn't you say it earlier? Do you know how much energy one gram of uranium produces? One gram of uranium-235 atoms can release 83126085757.9 joules of energy, which is 83126.0857579 megajoules. This energy is equivalent to the explosion of 19.86 tons of TNT explosives. Energy. Don’t talk about you once it explodes, everything around will be gone.” Wang Lao really wanted to kill Liu Yun.

However, Liu Yun didn't think such a thing would happen, because the remaining time for the exchange was running out.

[Ding, there is still 235 second left for the uranium-1 car. 】

[Ding, the uranium-235 car has no time to use, all the uranium in the engine has been used up, and the entire car is about to be destroyed. 】

Subsequently, the entire car became one atom after another that could not be distinguished by the naked eye and disappeared into the air.

"Where is this car?" Elder Wang asked in shock, why the good car suddenly disappeared.

"Uh, the car's engine can't withstand the energy produced by the fission of uranium and has been roasted to pieces by the remaining energy of the uranium."

"Hey, do you still have this kind of car? Go borrow another one for me to study."

Liu Yun hoped that Mr. Wang could succeed in the research, and asked the system silently: "Can the uranium-235 engine be researched?"

[Ding, the host should stop dreaming, the current technology cannot produce this material.The melting point of tetratantalum hafnium pentacarbide produced by current technology is 4215 degrees, and it is also the material that can withstand the highest temperature known so far.Since the uranium-235 engine is not driven by the release of heat energy to boil water, as the nuclear fission proceeds, the temperature reaches tens of thousands of degrees, and the existing materials cannot withstand the residual temperature generated by the controlled chain reaction of nuclear fission. 】

[The most important thing is that the current technology cannot reduce the nuclear reactor device to the size of the engine.When a chain reaction occurs, the nucleus is bombarded by neutrons, producing both energy and neutrons, which continue to bombard the nucleus to produce energy.The pressurized water reactor nuclear power plant reactor that is basically used in existing technology, this kind of reactor not only needs control rods to control the speed of nuclear fission, but also needs a complex cooling water system, which is impossible to compress into the engine. 】

[Moreover, the current technology cannot quickly remove the nuclear pollution caused by nuclear fission. It is not recommended to imitate the uranium-235 nuclear fission engine. 】

Well, there are reasons and evidence, so that Liu Yun can't refute.

"Old Wang, let me tell you the truth. The energy produced by nuclear fission was used in the car just now, but the nuclear fission container was compressed into a small size and put into the engine. Actually, there is nothing novel about it. The energy generated by nuclear fission is used to drive the engine to run, the engine runs fast and has sufficient energy, and the car naturally runs very fast."

"It can't be a nuclear reactor. If the nuclear reactor is so small, how can it dissipate heat?" Mr. Wang was full of curiosity.

Liu Yun said he didn't understand, so he could only ask the system: "System, how does the uranium-235 car engine dissipate heat?"

[Ding, uranium-235 releases a lot of heat energy in the reactor.This heat drives the engine piston, the movement of the piston drives the connecting rod, and the other end of the connecting rod is connected to the crankshaft flywheel, which in turn drives the wheels of the car.The whole process does not require heat dissipation, and is borne by the engine wall that can withstand high temperatures, and the temperature will eventually maintain a balance with the discharge of heat energy. 】

"Without dissipating heat, the heat energy is accumulated all the time, and finally forms a balance with the heat energy consumed by driving the engine gear."

"Hey." Elder Wang sighed and did not speak again.
