Chapter 333 Han Ziang who experimented on himself
When Han Ziang saw Liu Qi's eyes that were red from staying up late, he said:

"Is there any inspiration that you can't write down and then wait until daytime to verify it? Look at your eyes, they are as red as rabbits!"

Regarding Han Ziang's concerned tone, Liu Qize didn't say much, but took out five disc-like things from the bag and handed them to Han Ziang and said:
"I have designed a safety equipment that can resist the impact of small meteorites to ensure safety. Grandpa, when you are driving to work, you can stick this disc on the center of the roof of the car, and then turn on the switch to enter the protection trigger. pattern!”

However, Han Ziang looked at this disc, which was slightly smaller than the washbasin, with some disbelief. This thing could withstand the impact of the meteorite.

You must know that Han Ziang has also seen the electromagnetic rapid-fire cannons on the quarry, with their size and firepower, so Han Ziang said suspiciously:

"Can a small disk like yours really withstand the impact of a meteorite at more than ten kilometers per second?"

However, after Liu Qi heard Han Ziang's words, he immediately shook his head and said:

"Grandpa, you are wrong about one thing! Although the speed of a meteorite can reach thousands or even tens of thousands of meters per second before it enters the atmosphere, after entering the atmosphere, the friction of the atmosphere will greatly reduce the speed of the meteorite, and it will eventually fall. The speed of the ground is only a few hundred meters per second! If it is really thousands or even tens of thousands of meters per second, the electromagnetic rapid-fire cannon cannot intercept it!"

However, Han Ziang asked unconvincingly;

"If it really only had such a small speed, then how did the dinosaurs become extinct more than 65 million years ago!"

Yes, Han Ziang is a senior pilot and has been driving for many years, so the above assigned Han Ziang the position of squad leader. Of course, even the squad leader still needs to open a mining card.

Liu Qi could only helplessly explain to Han Ziang what air resistance is equal to the cross section of the object times the square of the speed, and the kinetic energy of the object is equal to the speed of the object times the mass of the object.

Although Han Ziang still didn't quite understand, he still took Liu Qi's disc and said he would install it and test it.

·······
"Hey! Monitor Han, what are you holding in your hand?"

However, the growth of mass is calculated based on the cube of the object. For example, for a cube whose length, width and height are one, its air resistance is one squared, but the mass of the object is the volume, which is the cube.

This is like a car and a large truck. The braking distance of a car from 100 kilometers is only about forty meters at most.

After Han Ziang entered the mining truck driver's lounge with the airbag equipment Liu Qi gave him, someone immediately saw what Han Ziang was holding.

Therefore, when the length, width and height of an object are two, the air resistance is only four, but the volume of the object is two cubed, which is eight. In this way, the kinetic energy consumed by air resistance and friction is small. Therefore, the atmosphere of the blue star is not suitable for large masses. The deceleration effect of meteorites is also greatly weakened.

However, the braking distance of a 50-ton heavy-duty truck can reach 100 meters per 100 kilometers. If it is a 100-ton king, its braking distance will be more than two to three hundred meters. This is why it is often said that trucks cannot stop. .

It is precisely because the air in the atmosphere has too weak a braking effect on giant meteorites that Liu Xiucai, on the advice of the think tank, let go of meteorites with a diameter of less than 100 meters and a weight of less than one million tons. , allowing the Blue Star’s atmosphere to slow down.

And Han Ziang didn't hide it, he immediately told the purpose of this thing, and also highlighted that this thing was developed by his grandson Liu Qi.

As soon as the mining truck driver in Han Ziang's class heard that this thing was actually developed by Liu Qi, he immediately rushed to get it.

After all, when Han Ziang ranked first in the global college entrance examination, Han Ziang showed off to them. Later, Han Ziang, who became the dean of the Mecha Research Institute, also told the truth to his drivers and had no intention of hiding it. So except for Han Ziang who kept one for himself, the remaining four were all divided up.

After Han Ziang installed the disc on the roof of the mining truck according to Liu Qi's installation requirements, he drove the mining truck to pull the rocks as usual.

But on the third trip, Han Ziang saw a large meteorite about one meter in diameter rushing towards him with tail inflammation.

However, just when Han Ziang was about to drift to avoid this meteorite, he suddenly remembered the disc on the roof of the car that Liu Qi had given him that morning.

So Han Ziang, who was originally going to turn the steering wheel, actually gave up turning the steering wheel and drove straight towards the spot where the meteorite was about to fall.

Just when the meteorite was still a hundred meters away from Han Ziang's car, Han Ziang suddenly felt as if something exploded on the roof of the car.

Then Han Ziang saw through the car window that the front of his car was wrapped by a huge semicircular balloon.

Then I felt something pressing on the car as soon as it sank, and then there was the sound of the safety balloon popping, and with this sound, the huge semicircular protective ball that originally covered the front of the truck. Gone.

After Han Ziang recovered from the shock, he got out of the car and saw the meteorite rolled aside by the deflection of the airbag ball, as well as the balloon fragments on the ground. Han Ziang knew that his grandson, Liu Qi's research The security issue of this mining card has been properly resolved.

So he immediately returned to the cab of the mining truck and used the communication equipment in the cab to call Liu Qixuan and said happily:

"Liu Qi, your kid's airbag experiment was successful. It can really block the impact of meteorites! Report to the superiors quickly and hurry up to produce it!"

Liu Qi couldn't help but frown after hearing Han Ziang's words, but then he said:
"Grandpa, you wouldn't take the initiative to collide with a meteorite after installing the airbag ball!"

Regarding Liu Qi's question, Han Ziang did not answer but said again:
"My mining truck driving recorder has a complete impact video saved in it. I will send it to you later so that you can refer to it and collect the experimental data! See if there is anything that needs improvement!"

··········
In the No. 1 underground city of Jianping, the highest power center, Liu Xiu's office, Liu Xiu was still looking at the methods gathered from all over the world to prevent the meteorite rain from hitting the mine cart.

But at this moment, Hao Xiaoxi happily ran over to Liu Xiu and said:

"Captain Ball, good news! Liu Qi, the director of the Mecha Research Institute, just reported that he has successfully developed a device to protect the mine card, and there is also a video of the experiment!"

While talking, Hao Xiaoxi also sent the video copied from Han Ziang's driving recorder to Liu Xiu's personal terminal.

When Liu Xiu took a look, he could naturally see Han Ziang's face, the scene of him facing the meteorite without dodging, and the scene of the airbag being opened and finally being smashed by the meteorite.

After seeing such a video, Liu Xiu naturally gave Hao Xiaoxi a decisive order to quickly contact a large factory that could produce such equipment to start production.
