According to the construction plan, Roland arranged an equipment room at each well point to accommodate all the devices required by the tee 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, the entire three-way system is formed.
Among them, the steam engine is responsible for pumping the well water to the water tower and the water 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 off the ground, and limestone and washing stone are suspended in it, which are used to precipitate magnesium and calcium ions in the water, and play the role of softening water. The clarified water will be directed to the lower secondary storage tank, and the floating objects in the water will be blocked 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, the float valve will be driven, and the electric motor will be turned on to supply water until the water level returns to normal. This process is much more stable than manual addition or steam engine transportation, and it also eliminates the need for any time. The trouble of standing by and observing.
Since both water supply and heating have been verified in advance, there will be no difficulties in this construction. The key lies in the power supply system, which is the first time for the town. Neither Carl nor the other members of the Mason Society 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 circuit knowledge Basically stay 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 Beipo Mountain.
Under the fog of Nightingale, the journey that originally took a quarter of an hour, took only three or four minutes to reach the destination.
Pushing open the wooden door, Anna and Lucia immediately noticed him, but the former only nodded to him because he was busy with his work, while the latter happily ran over, "Your Highness, good morning."
"Good morning," Roland nodded with a smile, then walked to Anna's side, "What are you busy with?"
"The new barrel and locking mechanism," she pointed seriously at the long steel pipes on the table, "your drawing is a bit unreasonable, I think it would be better to change it this way."
Amazing my Na, Roland couldn't help reaching out to touch the other's head, but was rejected by shaking back and forth, um... I seem to have seen such a scene before, he coughed twice, restraining his teasing mood, "Well , do as you wish."
Roland didn't mind her questioning her design. The gun drawings were inferred by him based on the principles. It was normal to have flaws and room for improvement, not to mention that Anna's own learning talent and comprehension ability far surpassed him, he felt One day, her understanding of learning will reach a level that she can't even match.
After a while, Anna put down the parts she had made, walked to Roland's side, 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 something new to try?"
"Ah... that's right," the prince looked at Lucia, "how did you separate the messy ore in the mine?"
"It's basically completed, the results are here," the latter handed a stack of notebooks 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 exclusion of impurities to obtain high-quality steel ratios, the elements involved have now been expanded to the resources that the entire North Slope mining area can provide. There aren't many tricks in this part, just a little bit of added experimentation.
Roland spread out the notebook, 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 Experiment No. 12, "Where is this ore?"
Lucia immediately found the test samples - they were packaged in transparent coated bags, which were a piece of rough stone and a packet of decomposed elemental particles.
And that dark rough stone, Roland felt as if he had seen it somewhere.
Wait, isn't it the same black stone that was sent to his office before? Since he handed it over to the alchemist, he also forgot about it and never paid attention to its news.
It turned out to be the mineral with the highest melting point in the North Slope Mountains
In the record book, Anna couldn't make a precise mark on the specific value of the melting point, so she could only describe it in words. Between ordinary, high and high, only its characteristic column was written as extremely high. .
As for the bag 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 extremely fine metal wire, twist it into a spiral shape, fix it on a glass frame, and then put the frame into the glass bulb, and the main part of the electric light is complete.
Of course, in order 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 into the bulb.
There is no doubt that these two steps can only be done by witches.
Roland found Agatha first.
Vacuuming is mainly because the filament becomes extremely active at high temperatures, and it is easy to oxidize and generate new oxides, and the result is a fuse. To achieve this effect, charging a non-reactive gas is equally effective, or even better.
Pure nitrogen is an excellent filler.
Using 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 vacuuming. When the other end is also exhausted by nitrogen, Soraya is responsible for sealing, and a simple incandescent lamp is done.
Looking at the palm-sized light bulb in his hand, Roland was filled with emotion. Such a thing that has been eliminated in later generations now represents the highest level of production in the town.
The next night, he called all the members of the town hall to the forecourt of the castle, and at the same time ordered his guards to put out 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, an orange-yellow light lit up in the center of the garden. It was not like a candle that would flicker in the cold wind and go out, and it was not like a bonfire. 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 expressions of the people and the peaceful scene said it all.
He brought electricity into this world.
