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 for easy management.

The complete set of equipment 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 entire three-way system is formed.

The steam engine is responsible for pumping well water to the water tower and storage tank. The former mainly provides domestic water to residences, and the latter is used to prepare heating water for boilers. The first-level storage tank is high above the ground, with limestone and washing stones suspended in it, which are used to precipitate magnesium and calcium ions in the water and soften the water. The clarified water will be directed into a lower secondary storage tank, and floating objects in the water will be caught by Soraya's special filter.

The water supply to the boiler is completed by an electric motor. When the internal water level is too low, the float valve will be driven, and the electric motor will be turned on to deliver water until the water level returns to normal. This process is much more stable than manual addition or steam engine delivery, and it also eliminates the need for water at any time. The trouble with people standing around 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 the small town. Neither Carl nor the other members of the Masons knew anything about electricity, so Roland planned to make a small model in the courtyard first, and then explain it to the Ministry of Construction after success - after all, he didn't know much about this aspect, and the circuit The knowledge basically stays 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 his thick coat and set off to the backyard of Beipo Mountain.

Traveling through the mist of the nightingale, the journey that originally took a quarter of an hour took only three or four minutes to reach the destination.

After opening 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, "Your Highness, good morning."

"Good morning," Roland smiled and nodded, then walked to Anna, "What are you busy with?"

"New barrel and locking mechanism." She pointed at several long steel tubes on the table seriously. "Your drawings are a little unreasonable. I think it would be better to change them like this."

My Na is amazing. Roland couldn't help but stretched out his hand to touch the other person's head, but was rejected by being shaken back and forth. Hmm... It seemed like he had seen such a scene before. He coughed twice and restrained his teasing mood, " Well, do what you want."

Roland didn't mind her questioning his design. He had deduced the firearm drawings based on the principles. It was normal for there to be flaws and room for improvement. What's more, Anna's own learning talent and comprehension ability far exceeded his own. He felt that One day, her understanding of knowledge will reach a level that even she cannot reach.

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

Uh... Roland couldn't help but be startled. Is this trying to make up for the previous caress?

He tried to rub her soft hair, and Anna raised her head with satisfaction, "Do you have anything new you want to trial-produce?"

"Ah...that's right," the prince looked at Lucia, "How are you doing at separating the messy ore in the mine?"

"It's basically completed, and the results are here." The latter handed a stack of notebooks to him. "But the test of mixing it with steel will probably take a long time because there are too many single elements separated."

"It's 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 elimination of impurities to obtain a high-quality steel ratio, the elements involved have now been expanded to the resources provided by the entire North Slope mining area. There are not many tricks in this part of the content, just a little bit of added experimentation.

Roland opened his book and checked the properties of various unknown minerals in the yard, and quickly found the element with the highest melting point. He pointed to the column marked Test Item No. 12, "Where is this ore?"

Lucia immediately dug out the test samples - they were sealed in transparent coated bags, including a piece of raw stone and a pack of decomposed elemental particles.

As for that dark rough stone, Roland felt like he had seen it somewhere.

Wait, isn't it the same as the black stone that was sent to his office before? After handing it over to the alchemist, he put the matter behind him and never paid attention to its news again.

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

In the record book, Anna could not accurately mark the specific value of the melting point, so she could only use words to describe it. Among ordinary, high and high, only its characteristics column said extremely high. .

As for the pack of simple particles, they are silvery white like most metal elements, and there is no difference.

Could this thing be tungsten?

But whatever, as long as it's refractory.

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

Of course, if you want to make it glow stably, there are two steps that need to be done - and this is also the most difficult part of the light bulb process: one is to vacuum, 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 only witches can do these two steps.

Roland found Agatha first.

The main reason for vacuuming is that the filament becomes extremely active at high temperatures and is prone to oxidation reactions to generate new oxides. The result is melting. To achieve this effect, filling with non-reactive gas is equally effective, or even better.

And pure nitrogen is an excellent filler.

Utilizing the principle that nitrogen is lighter than air, a simple downward exhaust method can easily fill the bulb with nitrogen, which is much simpler than the vacuuming step. When nitrogen is discharged from the other end, Soraya is responsible for sealing it, and a simple incandescent lamp is completed.

Looking at the palm-sized electric lamp in his hand, Roland was filled with emotion. Such a thing that has been eliminated in later generations now represents the highest production level of the town.

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

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

In an instant, a ball of orange light lit up in the center of the garden. It was not like a candle that would sway and go out in the cold wind, nor was it like a bonfire that flickered and went out. The illumination range is not large, only about a few meters, but the steady light standing against the wind is a sight that people have never seen before.

No explanation is needed at this point.

The unblinking looks on the people’s faces and the peaceful scene said it all.

He brought electricity into the world.
