"But then again, the airships used by major kingdoms in this era seem to be filled with hydrogen, not inert gas, helium, and it is like a large bomb!"

He complained helplessly and walked into the mechanical laboratory. Upton was holding several filaments of different materials and pondering hard, while Alvin quietly took out the zinc skin, graphite, carbon rods, electrolytes and other materials that had been prepared.

As for battery manufacturing, "zinc" and "graphite" are not uncommon as natural minerals. In the absence of "polypropylene fiber", cotton fibers can also be used to temporarily replace the fiber webs that adhere to the electrolyte.

The "carbon rod" is made of carbon, graphite and appropriate adhesive, and is made by extrusion and baking at 2200℃ and rotating sections. There is no problem in the process.

Secondly, in this era, "manganese dioxide" was widely used in the manufacturing of colorants, decolorizers, iron deferrants, and gas surfaces in the glass and enamel industries.

After entering the human body, it will damage the central nervous system and inhale a large amount of smoke and dust in a short period of time, which may cause "metal smoke heat", resulting in headaches, nausea, chills, high fever, and sweating.

Chronic poisoning will lead to neurasthenia syndrome, autonomic nervous system disorders, mental symptoms of excitation and inhibition of balance disorders, and toxic psychosis in severe cases, etc.

This is also the tip of the iceberg that unprotected slum workers are infected with serious diseases in extremely backward production methods. They fall one by one in glass factories, enamel fields, and lead-making places.

Finally, as a by-product of the production of potassium salts such as potassium carbonate, it is not difficult to prepare on a small scale under the existing industrial foundation. The simplest ammonia alkali method is to use "salt" sodium chloride and "limestone" to calcinate to produce quicklime and carbon dioxide. The ammonia gas is first passed into saturated salt water to form ammonia salt water, and then carbon dioxide is passed into the carbon dioxide to produce sodium bicarbonate precipitation with less solubility, and the required ammonium chloride solution.

However, if you want to prepare on a large scale on industrial basis, you need to use Hou's alkali production method, also known as the combined alkali production method. Of course, this is still a bit far away from the existing conditions.

"Just just now, the first batch of bicycles trial-made by Beckland Steel will arrive in Tingen by train tonight."

As he murmured to himself, Alvin's eyes gradually became wet, and a strange feeling surged around his body, and the stagnant potions in his body began to quickly digest and absorb them.

Take a light bulb and try to see if it is on?

He knew that the "grenade grenade" was nothing more than using the grenade to add a tail rod, insert it directly into the rifle muzzle, and fire it with an empty package to increase the range of the grenade.

Then add black graphite powder mixed with manganese dioxide, and after gently compacting it, he presses natural rubber as an isolation layer at the opening around the carbon rod, and the top of the carbon rod is covered with a tin-plated copper cap to prevent oxidation and rust, as the positive electrode metal.

But when he and Ivan turned off the gas lights and each of them was carrying a flashlight for testing in the laboratory, they were still shocked, and Captain Dick, Mrs. Saril, Old Dirk and others who came back to work after the holiday.

In the laboratory of the Mechanical Heart Team in Uttingen City, the world's first complete version of the flashlight was created.

"Well..." Alvin fiddled with the parts in his hand and nodded slowly.

After all, a battery in an old flashlight will not last long, and the more batteries 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.

Suddenly after hearing Alvin's murmur, Bulenes, who was rumbling around, was shocked and hurriedly advised:

"You're crazy and want to mess with that guy?"

The work of manufacturing batteries was busy until the next day. Under Alvin's prompt, Upton also successfully made a light bulb with tungsten wire, and rolled out the lamp with iron sheet, and improved the switch with patent leather copper wire.

In this way, a No. 1 battery with a diameter of about 3.4cm and a height of 6.1cm has been completed.

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

Hearing Brenés lying in his pocket, cursing the God of Steam from time to time, he often lamented that his men were too incompetent, so he almost lost his underwear.

First, the carbon rod was placed in the center of the "cup-shaped" lead, which was covered with cotton fibers, and evenly applied non-fluid electrolyte made of ammonium chloride and starch.

Then, with the blessing of the Generalist Potion, Alvin began to recall the structure of the dry battery little by little.

Upton is working hard, but unfortunately there are no finished products at the moment.

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

But he had no impression of what the "grenade gun" was.

In fact, if you think about it for a moment, you don’t need to throw the negative electrode downwards and a few centimeters away from the ground to see if the battery can stand up... You only need two simple wires with patent leather.

In memory, Alvin pressed two copper wires on the positive and negative poles of the battery, then touched the thread tip slightly, and repeated several times, a tiny but unusually bright spark suddenly flashed away.

Without any prompts, Upton, who racked his brains and thought hard, did not intend to disturb Alvin's meditation, was preparing to leave quietly and study the flashlight that he had been unable to put down and even held when he was sleeping.

"Anxiety, it's not the time!" Aiwen shook her head confidently, put away the finished battery, and began to make the next one with great knowledge.

Although this light is extremely weak, it is like the first fire in the eternal night, illuminating the future full of thorns in Evan's heart.

However, for the cheers of the "colleagues", Alvin threw Upton directly to the radiant eyes of Econser and others, and slipped back to the laboratory by himself.

After waiting for the tired Upton, he promised to take the lead in equipting members of the Tingen City Mechanical Heart Team with a flashlight to escape from the encouragement of Iconser's success and inducement. When he returned to the laboratory, he saw Evan holding a large barrel in his hand, frowned and said nothing.

"Grenade?"

Bournez, whose head was only half of his head was exposed in his top pocket, staring blankly at the dry battery in front of him.

"You're really a real generalist, Alvin!"

Many such weapons have been stored in the arsenal behind the completed Rupert Gate recently.

Upon hearing this, Upton's expression seemed even more confused.

...

"This is the dawn before the Second Industrial Revolution and the crystallization of the wisdom of the predecessors of mankind!"

The production process is so simple, but I actually need to thank Rossell, a fellow villager who once promoted the development of industry.

I couldn't help but feel curious and walked forward. After carefully looking at the barrel far thicker than the hunting rifle, I asked in confusion:

"Mr. Stinson, are you going to modify the firearm?"

In response, Alvin curled up the corners of his mouth and said with a smile:

"I heard that Lord of Storm has a temper as irritable as his title?"

Otherwise, with the medieval technological level, he could only barely make an ancient "Baghdad battery", and even more so than flashlights or radios.

At the same time, P=U*U/R, because the resistance of a unified lamp is certain, the greater the voltage, the greater the power, the brighter the bulb.

Although the surface of the hand-rolled iron lamp is very ugly, the light of the old tungsten filament bulb looks a bit dim, far less bright than LED and inert gas bulbs.

So the battery has been made, how to check whether it is effective?

Test on a multimeter?

There are no high-end things here.

After a while, he said to himself in a frustration:

"Damn... Steam, this bastard, really picked up the treasure. You actually let everyone steal the authority of the Lord of Storm through some extremely ordinary items. Rossel was right. Steam is indeed a sixth brother!"

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

Looking at the workbench not yet covered with packaging, shining with silver-white metallic luster and round-shaped battery, a knowing smile suddenly appeared on Alvin's face.

After a while, I heard Upton again, just like telling a story, and continued to whisper:

"Haha... When my sequence is high enough to create a large lightning rod and energy-absorbing device, you must pull up a handful of His wool. I think it should not be a big problem to supply power to one or two countries with His power."

"Acting Captain Econser also said that in order to increase the popularity of the bicycle, Beckland Steel Company specially invited Tingen City Hall officials and celebrities from all walks of life to hold a grand sale party. In addition to giving gifts to specific guests, it will also draw ten commemorative bicycles on site."

"Haha, they have a lot of sales methods." Alvin smiled, stopped the work, and asked with interest:

"So the party invited you?"

"It's us!" Upton said extremely seriously.
Chapter completed!
