According to the construction plan, Roland arranged an equipment room at each well site, and all the devices required for the tee were accommodated in it for easy management. Pen, fun, pavilion www. biquge。 info

The plant includes a steam engine, an electric motor, a power supply, a boiler and two storage tanks. Together with the water tower outside the room, the whole tee system is formed.

The steam engine is responsible for pumping water from the well, the former mainly to the house, and the storage tank, which is the heating water for the boiler. The primary storage tank is high above the ground, and limestone and washing stones are suspended in it, which are used to precipitate magnesium and calcium ions in the water and play a role in softening water. The clarified water is diverted to a lower secondary tank, where floating debris is stopped by Soloya's special filter.

When the internal water level is too low, the float valve will be driven to open the motor to send water until the water level returns to normal, which is much more stable than manual addition or steam engine transportation, and also eliminates the trouble of standing next to people to observe at any time.

Since the water supply and heating have been verified in advance, there will naturally be no difficulties in this construction, and the key is the power supply system, which is the first time for the town. Neither Carl nor the other members of the Masons Society knew anything about electricity, so Roland planned to make a trumpet model in the courtyard first, and then explain it to the Ministry of Construction after it was successful - after all, he didn't know much about it, and his knowledge of circuits was basically at the high school level.

With a reliable and stable power supply, the first step should be to create a qualified electrical device, that is, a light bulb.

Thinking of this, Roland put on a thick coat and set off for the backyard of the North Slope Mountain.

Under the mist of the nightingale, it would have taken a quarter of an hour to reach the destination, but it only took three or four minutes to reach the destination.

Pushing open the wooden door, Anna and Lucia immediately noticed him, but the former only nodded at him because he was busy with the work at hand, while the latter ran over happily, "Your Highness, good morning." ”

"Good morning," Roland nodded with a smile before walking over to Anna, "What are you up to?"

"New barrels and locking mechanisms," she said, gesturing earnestly at the long steel tubes on the table, "your drawings are a bit unreasonable, and I think it would be better to change them that way." ”

It's amazing to my Na, Roland couldn't help but reach out and want to touch the other party's head, but was shaken back and forth and refused, hmm...... He coughed twice and restrained his teasing, "Well, do what you want." ”

Roland didn't mind her questioning her design, the firearm drawings themselves were deduced by him according to the principles, and it was normal for him to have mistakes and room for improvement, not to mention that Anna's own learning talent and comprehension ability were far beyond his own, and he felt that one day, her understanding of knowledge would reach a height that he could not reach.

After a long while, Anna put down the parts she had made, walked over to Roland, and bowed her head slightly.

Belch...... Roland couldn't help but be stunned, is this to make up for the previous touch?

He tried to rub her soft hair, and Anna looked up contentedly, "Do you have something new that you want to try?"

"Ah...... That's right," the prince said, looking at Lucia, "how did you do with that messy pile of ore separation in the mine?"

"It's almost done, and the results are here," the latter handed him a stack of notebooks, "but I'm afraid it will take a long time to test the mixing with steel, because there are so many elemental elements separated." ”

"It's good to be able to do this," Roland encouraged approvingly.

This is also an extension of the Materials Improvement Program, which now involves elements that can be supplied throughout the North Slope mine, as opposed to the previous carbon control and impurity removal to achieve a high-quality steel ratio. There aren't a lot of tricks in this part of the content, just a little bit to add and try.

Roland spread out his notebook and checked the characteristics of various unknown minerals in the stockpile, and soon found the element with the highest melting point. He pointed to the column labeling Test Item Twelve, "Where's this ore?"

Lucia then searched for test samples—encapsulated in a clear coated bag, a piece of rough and a packet of decomposed elemental particles.

And that swarthy rough stone, Roland felt as if he had seen it somewhere.

Wait, isn't it just like the black stone that was sent to his office before, and since he handed it over to the alchemist, he has forgotten about it and never paid attention to it again.

It turns out that it is the mineral with the highest melting point in the mountains of the northern slope?

In the notebook, Anna could not accurately mark the exact value of the melting point, so she could only describe it in words, between ordinary, high, and high, except for the extremely high in its characteristic column.

As for the packet of elemental particles, like most metallic elements, it was silvery-white, and there was no difference to be seen.

Could it be tungsten?

But whatever, as long as it's refractory.

Roland asked Anna to process it into a very fine wire, twist it into a spiral, fix it to a glass shelf, and then put the shelf into a glass bubble, and the main part of the electric light was completed.

Of course, there are two more steps that need to be done to make it shine steadily - and this is where the bulb process is most difficult: one is to vacuum to isolate oxygen from reacting with the filament, and the second is to seal it to ensure that air does not escape into the bulb.

Undoubtedly, these two steps are also something that only witches can do.

Roland first found Agatha.

The main reason for vacuuming is that the filament becomes extremely active at high temperatures, and it is easy to oxidize and generate new oxides, which is the result of fuse. To achieve this effect, it is equally effective, if not better, to be filled with non-reactive gases.

Pure nitrogen is the perfect filler.

Using the principle that nitrogen is lighter than air, the bulb can be easily filled with nitrogen by using a simple downward venting method, which is much simpler than vacuuming. When nitrogen is also emitted from the other end, Soloya is responsible for sealing, and a simple incandescent lamp is done.

Looking at the palm-sized electric lamp in his hand, Roland felt a lot of emotion in his heart, such a thing that had been eliminated in later generations represented the highest production level of the town at this moment.

The next night, he summoned all the members of the town hall to the vestibule of the castle, and ordered his guards to extinguish the torches in the courtyard.

In the snowy night when twilight covered everything, Roland closed the switch on the circuit.

In an instant, an orange-yellow glow lit up in the center of the garden, and it was not like a candle flame that swayed in the cold wind or flickered like a bonfire. The illumination range is not large, only a few meters or so, but the steady light standing in the wind is a sight that people have never seen before.

No clarification is needed at this point.

The unblinking looks of the people and the serene scene speak for themselves.

He brought electricity into the world. (To be continued.) )
