"Of course, as I said at the beginning, although the ability violates common sense, it still has its internal laws, as long as we continue to summarize, one day, we can use the ability to rebuild our world like the original use of physical chemistry."

Tang Jing's words always have some demagogic qualities.

Of course, in the last days, the hypnotic brainwashing of positive energy still has a certain positive significance.

At least for the moment, everyone is full of hope for the future.

In addition to styrofoam, Chen Dui is most interested in the mouse.

Truth be told, the mouse doesn't match the style of the other items, and it looks like it's broken, and it's been put in a cardboard box as a prep part.

However, the boys' attention to the mouse is purely reminiscent of computer games, and in fact, in terms of materials, there is nothing new.

Tang Jing was very interested in the two tape measures.

The flat square plastic shell, the iron tape measure inside can be pulled out and automatically recycled, and it is estimated that all the boys have used this thing as a weapon to play with.

Many of them may have been cut off their hands.

"Does this have any special effect?"

Seeing that Tang Jing had been staring at the huge tape measure, Chen Du asked with some curiosity.

"We are now relatively mature in terms of technology, but there is still an extremely important thing missing in the process of industrialization."

"What?"

"Energy."

"Hmm."

Although this is a good statement, Chen Du doesn't know why she can think of energy when she looks at a tape measure.

"Like oil and gas?"

"It's pretty much the same, but we can't use those things yet."

"What does this have to do with the tape measure?" Chen Du was puzzled.

"The role of energy is nothing more than to provide heat and power, especially the latter, which is why the invention of the steam engine can greatly promote the industrial revolution."

Tang Jing sighed, "It's a pity that we don't have this ability at the moment. ”

"Provide energy and power?"

"Hmm."

"Doesn't the squad leader count?"

"Heating iron and making explosives, of course, is a good source of energy, but it is difficult to use it as power at present, and this is what we lack the most, otherwise, at least the elevator will not need to trouble Lu Shanshan and them, and the crane on the shelf will also need to have power to run in the future."

"Is it feasible to boil water with iron and then build a simple steam engine?" He Ying asked.

"It is feasible in principle, and with Chen Duan's current ability and accuracy, as long as the disassembly is carried out, it is completely possible to build a steam engine suitable for our use."

"So what are you doing?"

"It's not that simple." Tang Jing sighed; "Remember what I said, in the past, the size of the machine, after the ratio is reduced, may not be able to be used, even more so, things like the steam engine, not that it must not be able to run, but even if it does, the effect is very limited."

"Why?"

"Because we can't provide it with continuous energy, to take the simplest example, a steam train in the past, it carried enough coal to run thousands of kilometers, but a train the size of a toy car, it carried coal, do you think it can still run thousands of kilometers?

"A steam engine can be built, and it is feasible to use the squad leader's ability to boil water, but at our scale, the duration is a big problem, and in the final analysis, there will be a minimum of ordinary combustion phenomena, which limits us to the idea of cutting the fuel indefinitely to achieve a longer burning time."

Chen Du was gradually struggling to listen, but the general meaning was still understood.

"To put it bluntly, our biggest problem is storing energy."

"Yes, it's easy to make a fire, but to make the energy generated by this fire, even and sustained, is what we want to pursue." Tang Jing concluded.

"So what does this have to do with the tape measure?"

"Because I think of an ancient and simple way to store energy."

Chen Du was stunned at first, but with Tang Jing's gaze, he looked in the direction of the tape measure, and after a few seconds, he suddenly understood.

"Clockwork?"

"That's right." Tang Jing smiled, "When it comes to a continuous small amount of energy output, the first thing that comes to my mind is a mechanical watch. ”

"A few twists can go for days."

"Yes." Tang Jing smiled.

"Why didn't you think of it?" Chen Duan patted his head.

Making a clockwork device, whether it is a lift or a crane for a shelf, is a good power choice.

Of course, Wei Dalei himself is a huge source of motivation, but as a human being, he can't stay in one place forever.

Isn't it an excellent way to store power by letting Lao Wei wind up?

Tang Jing smiled, "It's useless to think about it earlier, the material needed for the spring is best carbon steel, we only have stainless steel now, although it can also be done, but the efficiency will be much worse." ”

"And this tape measure?"

"The steel tape measure is made of basically the same material as the clockwork, which is why I came up with the idea."

"Then let's do it right away."

"Don't worry, it's like this, but there are still a lot of problems when it comes to realization."

Tang Jing said, "If it's just a child's wind-up toy car, it doesn't make much sense, what we need is a uniform continuous power output, and the power of the clockwork is the largest at the beginning, and then gradually decreases, so we have to constantly adjust the torque lever, just like the internal structure of a mechanical watch." ”

"That's going to be complicated, isn't it?" As a parts processor, Chen Du was a little embarrassed.

"It's really difficult, just those large and small gears, it's enough for you to make it for a while, and the precision requirements of these parts are very high, and it's almost useless."

……

With the idea that if you make it one day earlier, you will use it one day earlier, Chen Du began to make clockwork in the afternoon.

He first cooperated with Wei Dalei to remove a tape measure from the shelf, and then disassembled it and took out the iron ruler inside.

Wait until you're done.

The next day, Tang Jing took out a piece of paper, which was drawn on a mechanical drawing of a clockwork device, and the dimensions in it were clearly marked.

This drawing almost fills the entire book, which densely marks the size of all the small parts.

It's hard to imagine that this is the result of a day.

With paper, Tang Jing no longer needed to draw drawings for Chen Du on the floor and on the wall.

After the first of the simplest and most experimental clockwork mechanisms was completed, everyone came running over to try it out. It was a primitive spring with a simple shell made of plastic, but it was very large, almost as tall as two humans.

A wind-up hole with a butterfly-shaped handle.

Everybody came up and tried it.

As a result, among the seventeen people in Qiming, except for Wei Dalei, none of them could be twisted.
