"Your Majesty, this is steam power."

In the eyes of a circle of onlookers at the Academy of Sciences, Yang Xin pointed to a copper ball in front of him that was spinning at high speed and said.

Well, that's actually a steaming ball.

Since we want to introduce steam power to the apocalypse, it is naturally indispensable to have such a verification product, at this moment His Majesty the Emperor is looking at this thing that is spinning while making a strange noise with a solemn face, in order to look good, the ball also has two small red wooden balls, which are thrown up by the rotating force, because the speed is too fast, it forms a red circle like a planetary ring around it.

"Of course, the steam engine is not this way, it can be, but it is too difficult for us at the moment, and all we can achieve is this piston type, which uses the power of steam accumulation to push the piston back and forth, and at the same time transforms it into the shaft that we need with the help of the linkage system, and this shaft drives everything in our design.

A train that can carry millions of pounds and gallop faster than a war horse.

A giant battleship with a length of more than 100 zhang,

It can be said that what we already have, what we can think of, can be driven by all machinery, spinning does not need manual labor or water power, striking iron does not need a hammer, and even ploughing the field does not need oxen.

This is our future. ”

Yang Dudu said confidently and proudly, like the scientists of the late nineteenth century who claimed that everything that should have been invented had already been invented.

"How does this thing fly?"

Song Yingxing said.

He would have picked and chose to find the steam-powered air battleship with the biggest brain.

There's a cannon on it.

"This needs this kind of thing."

Yang Xin said.

After saying that, the family who followed behind him carried a box.

Then they opened the box, and from it they took out a bundle of folded silk, which quickly unfolded under the gaze of a group of onlookers, and turned into a huge empty silk bag, the mouth of which was propped up with bamboo, and then took out of the box what looked like a bottle, and connected it to the rope attached to the silk. One of them lit the contents of the bottle, and the flame ignited instantly, and the other servants carried the mouth of the bag above the flame, and then the silk bag bulged and soon stood up towards the sky......

"It's called a hot air balloon."

Yang Dudu said in a shocked gaze.

The hot air balloon quickly and completely swelled, and with a casual wave of his hand, the family members immediately let go, and the huge hot air balloon rose with the bottle.

However, there was a rope underneath, and it was pulled up when it rose to a height of more than ten zhang.

"This stove is about twenty catties, it can bring up twenty catties of things, so as long as the hot air balloon on it is big enough, of course, it can also bring two hundred catties, two thousand catties, or even twenty thousand catties of things to the sky, without power it can only float with the wind, but what if we give it a power?"

Yang Xin said.

His Majesty the Emperor visibly showed a feverish gaze.

"But that's too early, after all, we don't even have a steam engine."

Yang Xin said.

"But you can make one big enough and take me into the sky."

Apocalypse said excitedly.

"This is no problem, but Your Majesty is in danger of the world, it is best not to ride, after all, this kind of thing has no safety guarantee, but it is enough for the army to reconnoiter the enemy, even if Your Majesty really wants to sit, it is best to hand it over to the minister to make, and it is best for my uncle to check and drive it before taking off."

Yang Xin said.

"What Hejian Hou did was foolproof?"

Hakka said on the side.

"Don't interject!"

Apocalypse said.

Hakka got up dissatisfiedly and stepped aside.

"Then leave it to the Hou of Hejian."

Apocalypse said.

This was expected by Yang Xin, which is also the reason why he has not taken out the hot air balloon over the years, after all, as long as he takes it out, the Apocalypse will definitely take it out, but at this time it is indeed time to take it out, the Apocalypse has always stayed in the palace and hardly goes out, at most he has been to the Yang family's hospital, His Majesty the Emperor is indeed very technical at this point. But in this way, he can't really see the suffering of the people, this hot air balloon is different, as long as it rises to a height of several hundred meters, with a large telescope, he can have an unobstructed view of the surrounding area of the capital, and even a radius of dozens of miles.

He would clearly see the depression of the surrounding countryside.

Especially in the ensuing drought, there was also famine around the area.

In this way, he will not lack a real understanding of the outside, after all, those boring words and other people's narratives are difficult for him to really understand.

In fact, he didn't look at the recital at all.

Nine thousand years old couldn't have told him all this mess.

As for security......

As long as it is nine thousand years old to inspect it in person, and personally accompany it, then there is basically no danger, the most dangerous thing of this kind of thing is fire, but modern hot air balloon accidents are carried by many people, in order to get enough strength usually use adjustable fire. And this is just a stove that burns whale oil, and the flame is just so adjusted, and it can't be big if you want to, as for the real military, it must be burning gasoline. At this time, Yang Xin was already able to refine gasoline through a simple oil refining kettle, that is, heating and then passing the boiling steam through a copper pipe soaked in cold water, and finally condensing the gasoline.

This can be given to the military.

With this thing, it will be much easier to fight a war, especially in the mountains.

A pair of eyes that rise to a few hundred meters will make the ambush a joke, and this year's ambush is not about lying in the grass in a gilly suit, in fact, it is just using the terrain to cover and gather in a ravine to wait, but this kind of ambush is meaningless in the field of vision of the observer on the hot air balloon.

"This steam engine is easy to say, but this cylinder is difficult to do."

Song Yingxing on the side said.

I have to say that he is still very discerning and has figured out the real difficulties.

The apocalypse who was looking at the hot air balloon above his head immediately returned to the topic, these days they have studied this steam engine countless times, and finally came to the conclusion that this cylinder, after all, everything else can be cast, and as long as it is cast, it is not worth mentioning, because the Ming craftsmen have a lost wax method.

These pig iron castings are really not worth mentioning.

And those small ones, which need to be strong enough, are made by skilled craftsmen, after all, Da Ming can even make a chiming bell.

In fact, before the birth of crucible steel, the level of steel smelting in Europe has not surpassed that of the East, their advantage is only that iron ore is too good, after all, the ore in the steel industry is the most important, even some modern special-purpose high-grade steel has to import iron ore smelting from Sweden.

Therefore, Yang Xin has always been concerned about Shilu Iron Mine.

But at present, the quality of wrought iron in Europe is not stronger than that of Daming's Suzhou steel, in fact, it is even worse.

The quality of these small parts forged by Sugang should not be much worse than that used by Watt, and it is unknown whether the latter is made of crucible steel.

But at that time, crucible steel had just been invented for not many years, and it has been used as a special material, and the price is quite high, after all, a furnace is just a dozen catties, and it has to go through a series of complex procedures, that thing is actually the selection of the best quality wrought iron cut and carburized and refined, through the graphite crucible to continue to increase the carbon content, add something to further remove impurities, from wrought iron to medium carbon steel.

Mainly making knives.

Anyway, this shouldn't be a problem.

But the cylinder is a real headache.

"One is that the object needs to be round enough, the second is that the piston is moving back and forth in it, and it is necessary to ensure that the steam does not leak out of it, and the third is that the cylinder must always be consistent up and down, so that the casting is difficult to make, even if it is not achieved by the lost wax method."

Apocalypse said.

"The easiest way to do this is to use a boring machine."

Yang Xin took out a pure principle schematic diagram from his mechanical diagram and said.

"This is cut from the inside, the inner wall is processed to a sufficient precision, there is no steam engine as the power, and the use of water power can barely be achieved, but this set of machinery is also very time-consuming, and the difficulty is not lower than that of the steam engine, so we still use a stupid method. Don't use iron for this cylinder for the time being, use tin, get a tin plate, and then find a skilled carpenter to make a cylinder with hard enough wood, this wood must be round enough, and the up and down error must be small enough, and then wrap the tin plate and knock it.

It certainly won't meet our requirements, but it's barely working.

The inside is then sealed with oil-soaked hemp rope, which blocks the leakage of steam. ”

He went on to say.

What else can I do at this time, I can only learn from Watt.

It is indeed difficult for such a steam engine to have practical value, after all, the air leakage is still very serious, and the final efficiency is also very low, but it can move, which is enough, as long as it can be moved, it is successful, as for the real practical can only wait for the cylinder boring machine, but the temporary boring machine can also be just a simple version, so that the cannon can be processed, and there is an essential difference between the cannon that has not been processed and the processed.

And these two things can make His Majesty the Emperor have no distractions in his heart for five years.

It's true.

Although the apocalypse is a bunch of skilled craftsmen here.

There are also famous scientists such as Song Yingxing, Xu Guangqi, and recently brought Wang Zheng and Li Zhizao here, people are actually unwilling to play with him, these people are all pillars of the imperial court, and they take Kuang Shi to help the people as their own responsibility, such as Wang Zheng was a pusher in Guangping before, and Li Zhizao was a Shaoqing in Taifu Temple, and he was forcibly called by him from time to time every day.

Occasionally, Mao Yuanyi would be called.

Even a medical scientist like Wu Zhiwang would be called, and even Wu Zhiwang, who was supposed to be appointed as the governor of Denglai, was forcibly changed to Guanglu Siqing by him.

In short, His Majesty the Emperor is surrounded by many talents.

But even so, the two things of the experimental steam engine and the boring machine have to make the apocalypse completely fall into it within five years, you must know that it took Watt twenty years, although the apocalypse started high, such as the mature principle and the supporting parts were directly given by Yang Xin, but five years is still a relatively ideal time, in fact, he can use ten years to get these, in Yang Xin's opinion is already very amazing.

Similarly, if the Apocalypse can really get these things out, then he can also be immortal, as for the outside affairs, there is no need for the emperor to worry about it, there is a combination of Yang Dudu and Nine Thousand Years Old, a pair of eunuchs and traitors, and the Ming Dynasty will not be able to die.
