Release that Witch - Chapter 445

[Chapter 438 Electricity and Light]

According to the construction plan, Roland arranged an equipment room at each well point to accommodate all the devices required for the tee connection for easy management.

The whole set of equipment includes a steam engine, an electric motor, a power supply, a boiler and two water storage tanks.

In addition to the water tower outside the room, it constitutes the whole three-way system.

Among them, the steam engine is responsible for pumping the well water into the water tower and the storage tank. The former mainly provides domestic water for the residence, and the latter is the heating water for the boiler.

The first-level storage tank is higher from the ground, and there are limestone and washing stones suspended in it, which are used to precipitate magnesium and calcium ions in the water and play a role in softening the water.

The clarified water will be introduced into the lower secondary storage tank, and the floating objects in the water will be stopped by Soraya’s special filter.

The water supply of the boiler is completed by the electric motor. When the internal water level is too low, it will drive the float valve and turn on the electric motor to send water until the water level returns to normal. The trouble of standing by and observing.

Since the water supply and heating have been verified in advance, there will naturally be no difficulties in this construction. The key lies in the power supply system, which is the first time for a small town.

Neither Carl nor the other members of the Stonemasons Association know anything about electricity, so Roland plans to make a small model in the courtyard first, and then explain it to the Ministry of Construction after he succeeds—after all, he doesn’t know much about electricity. Knowledge is 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.

Traveling through the mist of nightingales, it took only a quarter of an hour to reach the destination in only three or four minutes.

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

“Good morning,” Roland smiled and nodded, then walked to Anna’s side, “What are you up to?”

“New barrel and locking mechanism.” She pointed to several long steel tubes on the table seriously. “Your drawing is a little unreasonable. I think it would be better to change it like this.”

Awesome, my Na , Roland couldn’t help but reached out and wanted to touch the other person’s head, but was rejected by shaking back and forth, um… It seemed like he had seen such a scene before, he coughed twice, restrained his teasing mood, “Well, according to your Think about

it.”

Roland didn’t mind her questioning her own design, the blueprint of the firearms itself was inferred by him based on the principle, and it’s normal to have mistakes and room for improvement, not to mention Anna’s own learning talent and comprehension ability. Far surpassing himself, he felt that one day, her understanding of knowledge would reach a level that he could not even reach.

After a while, Anna put down the parts she made, walked to Roland, and lowered her head slightly.

Uh… Roland couldn’t help but startled, is this to make up for the previous touch?

He tried to rub her soft hair, and Anna raised her head contentedly, “Do you have anything new to try?

” How is the separation of the messy ore here?”

“Basically completed, the results are here,” the latter handed a stack of books to him, “but the test of mixing with steel may take a long time , because there are too many isolated elements.”

“It’s pretty good to be able to do this,” Roland encouraged approvingly.

This is also an extension of the material improvement plan. Compared with the previous control of carbon content and removal of impurities to obtain high-quality steel ratios, the elements involved have expanded to the resources that the entire North Slope mining area can provide.

There are not many tricks in this part of the content, only a little bit to add and try.

Roland spread out his notebook, checked the characteristics of various unknown minerals in the stockyard, and quickly found the element with the highest melting point.

He pointed to the column marked Test Item 12, “Where is this ore?”

Lucia immediately found the test samples—they were packaged in transparent coating bags, which were a piece of rough stone and a pack of decomposed elemental particles.

As for the dark rough stone, Roland felt as if he had seen it somewhere.

Wait, isn’t it the same as the black stone that was sent into his office before?

Since handing it over to the alchemist, he also put the matter behind him and never paid attention to its news.

It turns out that it is actually the mineral with the highest melting point in the North Slope Mountain?

In the record book, Anna was unable to accurately mark the specific value of the melting point, so she could only use words to describe it. Between ordinary, high and high, the only thing written in its characteristic column was extremely high. .

As for the package of elemental particles, it is silvery white like most metal elements, and there is no difference.

Is this thing tungsten?

But whatever, as long as it’s refractory.

Roland asked Anna to process it into an extremely thin wire, twist it into a spiral shape, fix it on the glass shelf, and then put the shelf into the glass bulb, and the main part of the lamp was completed.

Of course, if you want to make it glow stably, there are still two steps to be done-and this is the most difficult part of the bulb process: one is to evacuate, to isolate the oxygen from reacting with the filament; the second is to seal, to ensure that the air does not will escape into the bulb.

There is no doubt that these two steps can only be done by witches.

Roland first found Agatha.

The main reason for vacuuming is that the filament will become extremely active at high temperature, and it is easy to undergo oxidation reaction to generate new oxides, and the result is fusing.

To achieve this effect, it is equally effective, if not better, to inflate with a non-reactive gas.

And pure nitrogen is an excellent filler.

Using the principle that nitrogen is lighter than air, UU Reading www.sonicmtl.com can easily fill the bulb with nitrogen by adopting a simple downward exhaust method, which is much simpler than vacuuming.

When nitrogen gas is discharged from the other end, Soraya will be responsible for sealing it, and a simple incandescent lamp will be considered a success.

Looking at the electric light the size of a palm in his hand, Roland was full of emotions. Such a thing that has been eliminated in later generations represents the highest production level of the town at this moment.

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

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

In an instant, a ball of orange light lit up in the center of the garden. It didn’t flicker and extinguish in the cold wind like a candle, nor did it flicker like a bonfire.

The illumination range is not large, only about a few meters, but the steady light standing against the wind is a scene that people have never seen before.

No explanation is needed at this point.

The unblinking expressions of the people and the peaceful scene said it all.

He brought electricity into this world.
