The correct way to open the sprite

Chapter 139

Feng Yu said in surprise: "Is there a special metal mine in the Xueding Mountains?"

"Otherwise, where do you think the ore for the alloy tools made by Clarence came from?"

Feng Yu suddenly realized, and said, "Is the scale large?"

"It's not small, I remember that our kingdom was happy for a while, but it was later discovered that it was a special kind of metal mine, and it gave up large-scale mining.

But that kind of metal ore is very expensive. Except for a small amount of our ore supply to the alchemists of the elves, the rest of our ore are sold to the goblins in exchange for salt. "

Feng Yu said: "Then you should hurry up and contact your kingdom, don't sell that kind of ore to goblins, no matter how much you mine, I will cover it all."

Dick smiled and said, "You want to exhaust Clarence the Alchemist to death?"

Feng Yu said with a smile: "I'm just taking a hole first, and it won't be too late to make a large-scale acquisition when I find out the method of smelting."

Dick also smiled, and said, "Then you should prepare more money. Since you started supplying cheap salt, the price of special metal ores sold by the Kingdom to goblins has increased."

Feng Yu: "..." He lifted a rock and swollen his foot.

As the goblin caravans came to the Cattail City camp more and more frequently, Feng Yu had redundant workers on hand, and he added a batch of improved factories, not only using better steam engines, but also changing them. Precision processing machines.

For example, glass and ceramic factories have increased the pace of mechanized operations, making the entire production process more efficient, liberating more workers and joining new factories.

I don't know if it was luck, or Mason's skill points as a prospecting master were too full, but the patriarch really found a flint vein not far from the magnetite.

The initially smelted magnetite product brought back by the supply ship has been tested by Feng Yu and found to be extremely magnetic.

Feng Yu guessed that this thing should not only contain iron elements, but also other elements such as nickel and cobalt similar to magnetite on the earth.

Everyone, including Clarence, thought that Feng Yu was going to use magnets to make new weapons, and they all surrounded Feng Yu when he was playing with magnets, waiting to help him.

As early as when Feng Yu knew about magnetite, he was preparing for this day, made copper wire, and arranged for Dick and Allen to collect many types of natural resin in the Snow Top Mountains.

The production of fine copper wire is very cumbersome, but it does not have too high technical content.

In order to produce very fine copper wire, it is necessary to smelt copper water with high purity, and then let the copper water pass through small holes to discharge and cool, and initially make thick copper wire.

The thick copper wire is heated and pressed to form a thick copper wire of uniform thickness, which can be used to draw thin copper wire.

Stretching copper wire is to wind the copper wire on a row of rotating wheels. The rotation speed of these wheels is slightly faster than that of the other. When the copper wire passes between them, it will be slowly stretched step by step. Until it becomes a very thin copper wire.

Although this set of machinery is very large and cumbersome, the Cattail City camp with steam power and gear transmission already has the ability to build this set of machinery.

Feng Yu built such a set of copper wire drawing machine in a workshop, and pulled out a lot of copper wire. Although it is not as thin as the copper wire in the motor on the earth, it is barely usable.

As for the resin, it is used to brush on the surface of the copper wire to replace the insulating paint, but it is hard to say whether this thing will work, we can only experiment a little bit, after all, although resin was used as an insulator in the past on the earth, those are all composite material.

Feng Yu doesn't have that ability, so he can only do it slowly and try.He regrets it now, if he knew he would travel through time, he would learn chemistry and get mixed up again, maybe he has realized modernization now.

It's a pity that the programming and other professional knowledge he learned is basically useless compared to the primary industry.

Feng Yu carefully wound the copper wire brushed with resin on the frame that had been made earlier, and then let the Clarence welder weld all the wire ends.

In order to demonstrate, Feng Yu put the magnet outside as the stator, and then used the coil as the rotor, so that they can understand the origin of electricity more clearly.

Also for the sake of safety, Feng Yu did not dare to use a steam engine to drive the rotor to rotate at a high speed. Who knows if the electronics in the high magic world are the same as those on the earth? Small is also safer.

The news that Feng Yu used magnets to make new weapons spread like wildfire without his knowledge. Because of the strong performance of the existing weapons in the camp, idlers who are qualified to come to the research institute have come, waiting to see Feng Yu's new weapons .

Feng Yu looked at more and more people and said, "Why are you all here?"

Clarence said: "Aren't you going to make a new weapon, let's all take a look."

Feng Yu said in surprise: "Who said I'm going to make a new weapon?"

Clarence: "Um, aren't you going to use magnets to make new weapons?"

Feng Yu said with a smile: "So you came here because of this!"

Seeing everyone nodding, Feng Yu said: "Magnets are not used to make new weapons, but to study a new type of power similar to a steam engine."

Clarence said in amazement: "Just using a magnet and the copper wire tied to you can move like a steam engine?"

Feng Yu said with a smile: "Of course, binding has magical power."

Clarence said suspiciously: "Why does it feel that something is wrong?!"

"There's nothing wrong with it, I'll try it first and then I'll talk about it. Old Dick, I'll leave the task of generating electricity to you."

Dick was stunned: "What power generation?"

Feng Yu: "Use ai... shake the handle with your hands, it should be faster."

Dick pointed. "Shake this?"

"That's right, it needs to be shaken round and round, the sooner the better."

"That's easy, just watch mine!"

Dick grabbed the crank handle and slowly hi... shook it.

Feng Yu was afraid that the rotation speed would not be enough, so he used a set of gears to change the speed, and it would not be so labor-saving to shake, so he found Dick, a muscular prick.

As the coil rotor in the middle of the magnet painted in red and blue slowly accelerated, although everyone was confused, they all stared at the rapidly spinning rotor.

Feng Yu saw that the rotation speed of the coil rotor increased, and he used a small dry wooden stick to hold one output copper wire close to another copper wire.

As the copper wires are bent, the distance between the two copper wires is getting closer.

After a slight 'snap', the most miraculous thing happened in Gryen Continent this year. A bright blue arc appeared between the two copper wires, twisting and shining quickly.

Everyone staring at Feng Yu's movements let out an exclamation, and then the arc disappeared. Feng Yu saw that Dick had put down the crank in his hand and stepped back a long way.
