There was nothing but the big saffron and silk cloth hanging from the huge machine, but the workers here began to operate in an orderly manner.

When a cart of fiery charcoal that had already burned outside was poured directly into the furnace of the steam engine driven by a horse-pulled pulley.

Outside, another small steam engine, a blower began to blow.

The raging charcoal fire began to burn, and Li Shimin and the others watched in place, until about half an hour later, the huge flywheel on the main steam engine began to rotate slowly.

"It's moving!" A minister couldn't help but shout directly, and no one cared about him at this time.

Because I don't know if it's made of iron or steel, the huge flywheel is afraid that it doesn't weigh thousands of pounds, and it can't be driven by human power at all, and the flywheel starts to rotate like this, and the speed begins to get faster and faster.

When the speed of the flywheel reaches a certain level, the speed-controlled steam valve on it begins to automatically release steam and start to control the speed of the flywheel, and the huge flywheel begins to drive the machine next to it to start spinning.

To be honest, Li Ke didn't know if this was Datang's first steam turbine.

Although it is very different from the tall and heavy-duty steam turbines of later generations, which can easily reach 70,000 or 80,000 horsepower, it may only be convenient in principle, but it is right to use steam, right?

"Your Highness, all the best. The generator is working well! A lighting test can be performed. The director of the power plant ran over with an excited face.

"Father, you press this." Li Ke took the wooden switch from the side, and there was a long line connected to it.

To be honest, no one knows how much money Li Ke spent to strip off these cables in the warehouse, and the wires on the poles outside Datang can barely produce, but this kind of cable with insulating materials Datang can't produce.

The main reason is that the output of rubber and eucommia gum can't keep up, to be precise, eucommia gum, rubber is still a small sapling, there is a fart.

Eucommia ulmoides glue can also be used for insulation, but the output of eucommia glue is not good, and the processing of eucommia gum into special shapes of materials is also a problem in the current production line.

Therefore, these cables were pulled out by Li Ke from the warehouse in his mind, fortunately, he needed to touch these cables to bring it out directly, otherwise, Li Ke would have to dismantle it in it for several years.

Li Shimin took the switch: "Just pull it down?" ”

"yes, just pull it down." Li Ke nodded.

Li Shimin directly pulled the wooden switch directly to the other side, and then several large light bulbs arranged on the surrounding walls were directly lit! The light bulb tested here was also dismantled by Li Ke.

Datang bulb factory has been able to produce, but the efficiency is a little slow, and it will not be able to produce it until some subsequent machines and production lines are processed.

But the efficiency is not very high, until the time of the Shangyuan Festival next year, it is estimated that all the bulbs in Datang Sleepless City can barely keep up with the progress, but some important occasions inside must be disassembled by Li Ke.

It is also so-called.

The so-called "one life gives birth to two, two gives birth to three, and three gives birth to all things." "With the first, there are countless followers!

When the bright light bulb completely illuminated the whole venue, all the craftsmen were excited and directly applauded warmly, although Li Shimin didn't know what it meant, but he also began to applaud, and the other ministers naturally followed.

Although they didn't know what it was, they knew that such a glass-covered thing emitted a bright light far beyond countless candles, and this kind of light was certainly not afraid of the wind, and only a few light bulbs illuminated such a large venue so brightly.

Doesn't this mean that the night of Datang will finally be lit up by these light bulbs? Is this electricity?

"Historian, is the living room here?" Li Ke said.

"The minister is here." Several people stepped forward.

"Remember, this is a trivial switch that my father has set in motion, but it has opened a new era of energy for mankind! This is a small step for my father, but it is a giant step for human civilization! Li Ke said seriously.

"Yes!" The historian and the living man were a little excited, they were completely witnessing a major event in the Tang Dynasty, although they were ignorant and didn't quite understand what it meant.

But Li Ke knows that electricity will play a very important role in the era of human civilization, and this time is ...... Maybe it's going to be a long time! Unless one day there is some revival of aura in this world, and countless new energies and energies emerge.

Otherwise, electricity will run through most of the future civilizations of mankind.

Li Shimin glanced at Li Ke strangely, this ...... That's big enough.

Of course they can understand the word human being, Li Shimin's small step, a big step for human civilization? What that meant, he apparently thought more than the other ministers.

And to make Li Ke say this kind of thing, although Li Shimin doesn't quite understand what it means, but he knows that maybe the weight of this sentence in the future in the history books is much greater than the weight of his Heavenly Khan and the like.

"Your Highness, are we going to continue testing the next step?" The craftsman continued.

"Of course!" Li Ke nodded.

"Prepare to test the motor!" The craftsman here immediately spoke loudly.

The motor, that is, the motor motor, this thing...... Well, before you figured out all the principles of electricity, it was magical.

But after figuring out all the principles, the motor is really simple, and the simple motor can be wound by hand as long as it is not handicapped.

In Datang, its difficulty is not high, it is nothing more than copper wire, and the difficulty of copper wire production is slightly higher, but in fact, after the steam engine, copper wire and copper wire are much simpler.

At least it's much simpler than it used to be.

Wrap around a motor...... Naturally, it's incredibly simple.

Li Ke took Li Shimin and them to another room, this room, there is an improved Jenny spinning machine in it, oh, now called Shuwang spinning machine.

It can be powered by a completely new electric motor, and although it is not large, it also means that Datang's industrial revolution has completely begun.

The Shu King spinning machine has never been exposed to the outside world, although Li Ke changed the title of King of Qin, but its name has not been changed by the craftsmen, because the name is commemoration.

But today, dozens of ministers from the Tang Dynasty court saw this brand-new Shu King spinning machine with their own eyes.

It is actually two different from the original Jenny spinning machine taken out by Li Ke, most of the parts have been changed to iron, and in addition, it is also equipped with new power facilities such as bearings.

When one of the motors next to it was ready, several craftsmen quickly connected all its cables.

"You guys go straight to the ceremony, let's watch the ceremony." Li Ke saw that the craftsman was about to hand over the switch again, Li Ke waved his hand and said with a smile.

"Yes!" This craftsman was not polite, and directly said loudly: "The motor test is the first time, ready to start." ”

More than a dozen craftsmen around the motor stared at the motor without blinking, each holding a notebook and pen and paper in their hands.

After saying that, the craftsman directly pressed the switch in his hand.

Then the motor spun fast, especially the flywheel on the outside. All the craftsmen immediately began a series of processes such as inspection and documentation.

When they were done, the motor stopped again and they began to strap the motor's flywheel.

When the belt was ready, the craftsmen restarted the motor, and when the motor began to spin, driving the spinning machine's flywheel to spin rapidly, a dozen silk threads were spun at the same time at a terrifying speed, and wound around the spindle.

This scene made all the ministers crazy, and they felt for the first time what a new energy era is!
