The Uncanny: The Knowledgeable Returns From Warhammer

Chapter 42 The First Flashlight
"But having said that, the airships used by the major kingdoms in this era seem to be filled with hydrogen instead of the inert gas helium. It's like a big bomb!"

With a bit of resignation, he walked into the mechanical laboratory. Upton was holding several filaments of different materials and thinking hard, while Ivan quietly took out the materials such as zinc skin, graphite, carbon rods, and electrolytes that had been prepared. .

As far as battery manufacturing is concerned, "zinc" and "graphite" are not uncommon as natural minerals. In the absence of "polypropylene fibers", cotton fibers can also be used to temporarily replace the fiber mesh with electrolyte attached.

The "carbon rod" is made of carbon, graphite and an appropriate binder, which is formed by extrusion, baked and rotated at 2200 ° C, and there is no problem in the process.

Secondly, "manganese dioxide" has been widely used in the manufacture of colorants, decolorizers, iron removers, and gas-proof surfaces in the glass industry and enamel industry in this era.

After it enters the human body, it will damage the central nervous system, inhale a large amount of smoke and dust for a short time, and "metal fume fever" may occur, such as headache, nausea, chills, high fever, and sweating.

Chronic poisoning will lead to neurasthenic syndrome, autonomic dysfunction, mental symptoms of imbalance between excitation and inhibition, and in severe cases, toxic psychosis and so on.

This is also the tip of the iceberg of unprotected slum workers, infected with diseases in extremely backward production methods, one after another in glass factories, enamel factories, and lead factories.

Finally, ammonium chloride is a by-product of the production of potassium carbonate and other potassium salts. It is not difficult to prepare on a small scale under the existing industrial foundation. The most convenient ammonia-soda method is produced by calcining "salt" sodium chloride and "limestone". Quicklime and carbon dioxide, ammonia gas is passed into saturated brine to form ammonia brine, and then carbon dioxide is passed into to generate sodium bicarbonate precipitate with low solubility and the required ammonium chloride solution.

But if you want large-scale industrial production, you need to use Hou's soda production method, also known as the combined soda production method. Of course, this is still far away from the existing conditions.

Then, under the blessing of the enlightened potion, Ivan began to recall the structure of the dry battery a little bit.

First, the carbon rod is placed in the center of the "cup-shaped" lead skin, which has been covered on the cotton fiber, and the non-fluid electrolyte mixed with ammonium chloride and starch is evenly applied.

Then he added black graphite powder mixed with manganese dioxide, and after light compaction, he pressed natural rubber on the opening around the carbon rod as an isolation layer, and the top of the carbon rod was covered with a tin-plated copper cap to prevent oxidation and rust. as the positive metal.

In this way, a No. 3.4 battery with a diameter of about 6.1cm and a height of [-]cm has been completed.

Looking at the chubby battery on the workbench that has not been covered by the packaging, shining with silver-white metallic luster, Ai Wen suddenly showed a knowing smile on his face.

The production process is so simple, in fact, we need to thank the fellow villager Russell who once promoted the development of the industry.

Otherwise, with the level of medieval technology, he could barely make an ancient "Baghdad battery", let alone a flashlight or a radio.

So the battery has been made, how to check whether it is effective?
Test it with a multimeter?
There are no such high-end gadgets here.

Take a light bulb and see if it lights up?

Upton is working hard, but unfortunately there is no finished product yet.

In fact, after a little thought, there is no need to throw the negative electrode down a few centimeters from the ground to see if the battery can stand up...just two simple wires painted with paint leather.

In recollection, Ivan pressed two copper wires on the positive and negative poles of the battery respectively, and then slightly touched the wire ends. After repeated several times, a small but extremely bright spark suddenly disappeared.

And although this ray of light is extremely weak, it is like the first fire in the eternal night, illuminating the future full of thorns in Ai Wen's heart.

"This is the dawn before the second industrial revolution, and it is also the crystallization of the wisdom of human sages!"

"One day, this world will also have Emperor-class battleships, light spears, cyclone torpedoes, and tactical nuclear weapons... and let humans get rid of ignorance, so that evil gods and aliens can experience the punishment from technology!"

While muttering to himself, Aiwen's eye sockets gradually became moist, and a strange feeling surged all over his body, and the stagnant potion in his body began to be rapidly digested and absorbed.

"You are really a true generalist, Aiwen!"

Brenes, who only had half of his head exposed in his jacket pocket, stared blankly at the dry battery in front of him.

After a long while, he murmured to himself angrily:
"Damn it... that bastard Steam really found a treasure. You actually allowed everyone to easily steal the authority of the Lord of Storms through some unusual items. Roselle was right, that guy Steam is indeed a Old Six!"

Listening to Brenes lying in his pocket, he cursed the god of steam for being too insidious, and from time to time he felt that his subordinates were so incompetent that he almost lost his underwear.

In this regard, Ai Wen slightly raised the corners of his mouth and said with a smile:
"I heard that the Temperament of the Lord of Storms is as violent as his title?"

"Hehe... When my sequence is high enough to create large-scale lightning rods and energy-absorbing devices, I must take a good amount of his wool. I think it shouldn't be too big to use his ability to power one or two countries. question."

Suddenly hearing Ivan's murmur, Brenes, who was muttering non-stop, was startled, and hurriedly advised:
"Are you crazy and want to provoke that guy?"

"Relax, now is not the time!" Ai Wen shook his head confidently, put away the finished battery, and started to make the next one with ease.

After all, one battery in an old-fashioned flashlight can't last long, and the more batteries connected in series, the higher the voltage will be. The series voltage is equal to the sum of the voltages of each battery, and the current remains unchanged.

At the same time, P=U*U/R, because the resistance of a unified bulb is constant, so the higher the voltage, the greater the power, and the brighter the bulb.

……

The work of making batteries was busy until the next day. Under Ivan's prompting, Upton successfully made a light bulb with tungsten wire, rolled out the lamp tube with iron sheet, and completed the switch with lacquered copper wire.

And in the laboratory of the Mechanic Heart Squad in Tingen City, the world's first complete flashlight was manufactured.

Although the surface of the hand-rolled tin lamp is ugly and bumpy, the light of the old-fashioned tungsten bulb looks a little yellow, and it is far less bright than the LED and noble gas bulbs.

But when he and Ivan turned off the gas lamp, and each of them took a flashlight to test in the laboratory, Ikanser was still shocked, and Captain Dick, Mrs. Salier, and the old man who came back to work after the holiday Dirk et al.

However, in response to the cheers from "colleagues", Aiwen directly threw Upton to Ikanser and the others, who were full of eyes, and slipped back into the laboratory by himself.

Upton, who looked tired, promised to be the first to equip each member of Tingen City's Mechanic Heart team with a flashlight. Then he broke away from Ikanser's persuasive encouragement, and when he returned to the laboratory, he saw Aiwen forehand Holding a large gun barrel, he frowned and said nothing.

Feeling very curious, he leaned forward, carefully looked at the barrel, which was far thicker than the shotgun, and asked confusedly:
"Mr. Stimson, are you going to modify the gun?"

"Yes!" Ivan nodded, and sighed helplessly: "I want to make a grenade gun, but unfortunately I encountered some difficult problems."

"Grenade gun?"

Hearing this, Upton looked even more confused.

He knew about the "gun grenade". It was nothing more than using a grenade with a tail rod, inserting it directly into the muzzle of a rifle, and firing it with a blank shell to increase the range of the grenade.

A number of these weapons have recently been stored in the armory behind the near-complete Rupert's Gate.

But he didn't have the slightest impression of what a "grenade gun" was.

Without any prompting, Upton, who was puzzled after racking his brains and thinking hard, originally didn't intend to disturb Ivan's contemplation, and planned to leave quietly, and then studied the recent love that he couldn't put it down, even sleeping When flashlight.

But after turning around and walking a few steps, he hesitated for a while, turned around, and said softly:

"Acting Captain Ikanser said just now that the first batch of bicycles trial-produced by the Backlund Steel Company will arrive in Tingen City by train tonight."

"Hmm..." Ivan fiddled with the parts in his hand, and nodded slowly.

After a while, I heard Upton again, as if telling a story, and continued to whisper:

"Acting captain Ikanser also said that in order to increase the popularity of bicycles, Backlund Iron and Steel Company specially invited officials from the city hall of Tingen City and celebrities from all walks of life to prepare to hold a grand launch party. In addition to giving gifts to specific VIPs, Ten commemorative bikes will also be drawn on the spot.”

"Hehe, they have a lot of sales methods." Ai Wen smiled, stopped his work, and asked with great interest:

"So you're invited to the party?"

"It's us!" Upton said very seriously.
