Release that Witch

438. Chapter 438 Electricity and Light

    According to the construction plan, Roland arranged a equipment room at each well point to accommodate all the equipment needed for the three links for management.

    The complete equipment includes a Steam engine, an electric motor, a power supply, a boiler and two cisterns. Adding a water tower outside the room constitutes the entire three-way system.

    The Steam engine is responsible for pumping well water into the water tower and the storage tank. The former mainly supplies domestic water to the house, while the latter is the heater water for the boiler. The first-class reservoir is higher than the ground, and there are limestone and washing stones suspended in the tank for precipitating magnesium and calcium ions in the water to play the role of soft water. The clarified water will be introduced into a lower-level secondary storage tank, and the floating material in the water will be stopped by Soraya’s special filter.

    The boiler’s water supply is completed by the electric motor. When the internal water level is too low, the float valve will be driven to open the motor 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 is also free. Need someone to stand next to observe the trouble.

    Since both the water supply and the heating have undergone preliminary verification projects, the construction will naturally not have any difficulties. The key is the power supply system, which is the first time for small town. Whether it’s Karl or other members of the Stonemason, it’s definitely not clear about electricity, so Roland intends to make a small model in the courtyard, and then explain it to the Ministry of Construction after success. After all, he doesn’t know much about it. Circuit 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 a thick coat and set off for the Northern Slope Mountain backyard.

    Under the mist of Nightingale, it took a quarter of an hour to reach the destination in just three or four minutes.

    Pushing open the wooden door, Anna and Lucia immediately noticed him, but the former was busy with his hands and only nodded at him. The latter ran over cheerfully. “His Highness, good morning.”

    “Good morning,” Roland nodded with a smile, then walked over to Anna. “Where are you busy?”

    “The new barrel and locking mechanism,” she pointed carefully to the several long steel tubes on the table. “Your drawings are somewhat unreasonable. I think it would be better to change this.”

    Amazingly my Na, Roland couldn’t help but reach out and tried to touch the other’s head, but was shaken back and forth, oh…Such a scene seems to have been seen there. He coughed twice and converged on the mood of teasing. “Well, do it according to your ideas.”

    Roland does not mind her own design challenge, the gun drawing is his own according to the principle of self-inference, there are flaws and improve the scope of normal but, not to mention Anna’s own learning talent and ability to understand far more than himself, he felt that one day, Her understanding of learning will reach a height that she cannot attain.

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

    UhRoland can’t help but have to make up the previous touch?

    He tried to lick her soft hair, and Anna looked up with satisfaction. “Do you have something new to try?”

    “Ahhhh……That’s right,” the prince looked at Lucia. “How are you doing the separation of the messy ore in the mine?” ”

    “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 elemental elements separated.”

    “It’s great to be able to do this,” Roland praised.

    This is also an extension of the material improvement program. The elements involved now extend to the natural resource that the entire Northern Slope Mining area can provide, compared to previous control of carbon content and exclusion of impurities for high quality steel. There isn’t a lot of cleverness in this part of the content, only a little bit to add to try.

    Roland spread the book and looked at the characteristics of the various unknown minerals in the yard, and quickly found the highest element of Melting Point. He pointed to the column labeled Test No. 12. “Where is this ore?”

    Lucia then found the test samples – they were packaged in a transparent coated bag, a rough stone and a packet of decomposed elemental particles.

    And that dark stone, Roland felt like he had seen it.

    Wait, isn’t it the same as the black stone that was sent to your office before? Since I handed it over to alchemist, I have left it behind and I have never paid attention to it.

    As a result, it is actually the highest mineral in Melting Point in Northern Slope Mountain?

    In the record book, Anna can’t accurately mark the specific value of Melting Point, so it can only be described by language. It is between ordinary, high and high, but its characteristic column is written in the pole. high.

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

    Is this stuff tungsten?

    But take care of it, as long as it is hard to melt it will be alright.

    Roland asked Anna to process it into a very thin wire that was twisted into a spiral, fixed on a glass frame, and then placed in a glass bubble, the main part of the lamp was completed.

    Of course, if you want to make it glow steadily, there are still two steps to be done – and this is the most difficult part of the bulb process: one is vacuuming, the oxygen is isolated from the filament; the second is sealing, ensuring that the air is not Will break into the bulb.

    There is no doubt that these two steps can only be done with a witch.

    Roland first found Agatha.

    The vacuum is mainly because the filament becomes extremely active at high temperatures, and it is easy to generate an oxidation reaction to form a new oxide, and the result is melting. To achieve this effect, it is equally effective or even better to fill in unreacted gases.

    Pure nitrogen is an excellent filler.

    Using the principle that nitrogen is lighter than air, a simple down-drain method makes it easy to fill the bulb with nitrogen, which is much simpler than the vacuuming step. When the other end is also nitrogen, Soraya is responsible for sealing, and a simple incandescent lamp is done.

    Looking at the slap-sized electric lights in his hand, Roland felt a lot of emotions in his heart. This is something that has been eliminated in later generations, but at the moment it represents the highest level of production in small town.

    The next day In the evening, he summoned all members of the City Hall to the vestibule of the castle, and ordered the personal guard to extinguish the torch in the yard.

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

    In an instant, the center of the garden lit up with a group of orange-yellow light. It was not swayed and extinguished in the cold wind like the Candlelight, nor was it as bright as a bonfire. The range of illumination is small, only a few meters, but the steady light that stands in the wind is a scene that people have never seen before.

    No instructions are required at this time.

    The unrequited look and quiet scene of the people illustrate everything.

    He brought electricity to the world.
