Chapter 1106: BRI-100 “Shakti” Dynamo

25th September 1692

Imperial capital Bengaluru, Akhand Bharatiya Empire

News about the construction of the Metro spread throughout the media circles as soon as the tender meeting ended. The city panchayat was swarmed by a large group of reporters as if they were going to interview an international superstar.

The onlookers on the road were extremely curious about what had happened for the reporters to be in such a frenzy, so those who did not have anything urgent to do or those who had some time to spend stayed back and decided to watch the fun from the side.

The police officers guarding the panchayat were sweating profusely, trying to control the journalists; they felt like these people were even more troublesome than an angry crowd. After all, if they force their hand even a little, these reporters will write as if they were abused by the police.

Thankfully, things did not devolve to the worst situation as the old man of the panchayat, Shri Venkatapathy Gowda, came out of the office to control the situation.

“Please, please..everyone.. calm down, I will answer the question one by one, let the police do their job.”

Despite looking like he was in his 60s, his voice was extremely loud as it reverberated throughout the compound.

The journalists quieted down and allowed the police to set up a perimeter for crowd control.

Venkatapathy nodded in satisfaction and came forward. He noticed the journalist from Bharatam Daily, so he directly picked her.

Shweta was overjoyed to get the opportunity, so controlling her emotions, she quickly asked, “Respected Sir, can the people of the city know what the construction is about?”

Venkatapathy nodded, “In simple terms, it is a train that is used to move people within the city. As everyone already knows, the capital is constantly expanding and the important areas of the capital have become a little congested, hence, metro is a solution that was put forward by the panchayat in order to alleviate this problem by implementing a metro rail system where people can travel from one part of the city to another within an hour, as opposed to several hours of drive before.”

Being pointed at next, the reporter from the Times of Bharat asked in curiosity, “Excuse me, sir, the word metro has been used by Her Majesty’s famous work, ‘2012’. Is the metro system that is being implemented now, similar to the depiction of Her Majesty the Empress?”

Venkatapathy smiled, “Yes, it is very much related because it is Her Majesty’s work that gave us inspiration to set up an intercity railway transportation system.”

The reporter from The Observer asked, “What is the investment, sir? And has the feasibility study been done?”

“Hmm,” Venkatapathy stroked his chin and finally nodded his head, “The investment is around 200 million Varaha. As for the feasibility study, it is already done at the end of the panchayat. We estimate that the metro is capable of cutting down the traffic drastically by at least 30 to 40%, but as far as construction feasibility is concerned, I currently do not have the data, and I will hold a separate demonstration when I get the chance. But I’m not too worried since the project actually is approved by the emperor’s office, His Majesty the Emperor approved the project himself, and Prince Agni is currently in charge.”

This was big news; the sound of furious writing was immediately heard, and the next moment, the questions continued, “Who is the contractor, sir?”

“It’s a famous and well reputable construction company known for constructing complicated infrastructure, the Frontier Construction Firm, so the quality of metro infrastructure is guaranteed.”

“Excuse me, Sir…”

—

Only a few days later, citizens of Bengaluru noticed an odd scenery in some parts of the empire; the usually three-lane roads had actually become busy, and it was not because there was a sudden surge of traffic, but because one of the lanes was closed and large wooden planks were placed, diverting the traffic to the corner of the road.

“Namma metro?”

Looking at the writing on the planks, the pedestrians walking on the footpath were confused.

“What the hell is this?” a businessman from Colombo said out loud with confusion.

A jewellery shop owner, just opening the store and sprinkling some water early in the morning, looked at the plank and replied, “It is said that an intercity rail network will be constructed in order to curb the traffic.”

An image immediately appeared in the businessman’s head, “Like the Metro in Her Majesty’s novel?”

The shop owner nodded towards the merchant, “Exactly like that, but instead of being powered by a Vedic drive, it’s powered by steam.” The merchant rolled his eyes. Of course, it is run by steam. He was not foolish enough to believe there was something as magical as the Vedic energy drive. “So all the roads are like this?” He had just got off the train an hour ago, so he did not know the situation in the entire city.

The jewellery shop owner shook his head, “No, the metro track cuts through localities and residential as well as commercial areas.” “After all, what’s the use of this metro if it only follows the path cars and carriages follow?”

“That is true.”

Soon, the sound of a steam engine starting was heard, and a drilling machine powered by hydraulics began to operate. The jewellery shop owner was immediately annoyed because of the sound and vibrations that were bound to scare away his customers.

The merchant, after seeing the jewellery shop owner leave unhappily, simply looked into the gaps of the planks with curiosity, just like the other people on the footpath.

30th September 1692

Gangapuri, Akhand Bharatiya Empire

For a whole week nothing happened in Bengaluru other than the noise pollution brought by the digging of soil and rock in order for the pillars to rise, but in the meantime, Vijay had travelled to Gangapuri in secrecy because he heard back from Anand Binoy, and he had succeeded in inventing the dynamo.

As the car came to a halt in front of the Binoy Research Institute nestled in the forests of Gangapuri in absolute secrecy, Vijay got down from the car and immediately met with Anand Binoy.

“Can I see it?” Vijay’s eagerness showed, rare in recent times; after all, there was nothing that excited him much as of late.

Anand understood the emotions of His Majesty. He was excited to show it to him as well, so he immediately took the emperor to the largest warehouse of the research facility and showcased the gigantic behemoth with a smile.

Vijay looked at the monolith, a gigantic metallic motor-shaped object that was lying on the ground, giving off a sense of weight.

“This is it?” he asked without even turning his head.

“Yes, your majesty, this is the device I invented that can harness the rotational energy and turn it into electricity,” he smiled with pride, “I named it BRI-100 Shakti Dynamo.”

“It’s a good name,” Vijay unconsciously praised, but honestly, he couldn’t care less; the only thing on his mind was the monster in front of him.

Vijay finally looked at Binoy and asked him to explain about the giant.

“It is a dynamo that is capable of outputting over 110 Vidyut’s, 100 kilo-haris of power and 910 Binoys of current.”

Vijay immediately did the conversion in his mind, and it’s basically 110 volts, 100 kilowatts and 910 amperes. With some calculation, that’s basically enough to light up around 1200, 16-candle incandescent bulbs. Vijay’s eyes lit up. It’s not a small number.

“What type of output does it give? Is it direct current?” he asked, but his question left Anand confused. “Direct current?” Anand had never heard this term before, but something flashed in his mind. “Are you referring to the way the current is outputted, your majesty? It is continuous, is this what you refer to as direct current?”

“Ah!…erm…yes,” Vijay had completely forgotten that people didn’t differentiate between direct current and alternating current at the early stages of electrification. Even in his last life, people like Faraday, Edison and everyone else only thought there was one type of current, the continuous kind that was previously observed in the batteries, which is a concept older than the dynamo and other devices where it could be observed.

Binoy didn’t know what His Majesty was thinking but he was lost in thought himself, “At first the current I was getting was not continuous, it moved up and down, it fluctuated too much, making it unable to be used, so I made a device using 120 mica insulated 420 mm copper segments in order to make a device which I called a commutator, this was helpful in stabilising the current and giving a steady output.”

“Is this kind of current useful, your majesty?” he asked in curiosity. “Is there anyone else researching this topic?”

Vijay was embarrassed, but he did not change his expression and nodded, “Yes, a concept called alternating current and direct current has been established. If I’m not mistaken, your dynamo naturally produced alternating current, but your commutator device converted it into direct current.”

“As for alternating current, I’m not too sure of its uses, but research is going on in this department. Put that aside, how does this work?”

Binoy was immediately led astray and started to talk about the work.

“It uses a steam engine to power it, your majesty, a Bhairavi Jalapudra first-generation naval engine to be more specific, because it requires a horsepower of at least 175 and an operating speed of over 700 RPM.”

Only now did Vijay see the naval engine that is used to power 1000-tonne full metal ships placed right next to the dynamo. The dynamo was so massive that he somehow even ignored the gigantic and the biggest steam engine ever produced. Standing between these two giants, Vijay felt like a mouse.

“The operating speed could not be matched, so I had to find someone to manufacture a complex gear system with a gear ratio of 1:18.42 to make it work. Currently, the dynamo is connected to the steam engine using the gears, but unfortunately, using this system instead of a direct connection has led to a loss of efficiency. If everything went according to my plan, with the steam engine delivering 700 RPM naturally, I calculated an efficiency of 88 to 92 percent, but now it is at 70 to 75 percent.”

Vijay was left in thought, the gear ratio was unexpectedly complex, but thinking about the 35 to 40 RPM the Bhairavi engine naturally produced, he understood that it was needed. But is it enough? Converting 40 RPM into 700 is not that easy. He did calculations in his mind, and applying the gear ratio Binoy mentioned, the minimum horsepower an engine would require to run the gear at that speed would be around 158 horsepower, so that checks out.

Bhairavi easily clears it. But is the torque enough? He calculated it once again, using the formula Torque = Power × 60 / (2π × RPM). He got 29,564 newton metres. He frowned. The Bhairavi was falling a little short, around 4500 newton metres short.

‘So even though it is running at 700 RPM, the torque behind it is not up to mark, no wonder the efficiency is not too high and there is so much loss,’ Vijay thought to himself, but he did not say any of this.

“That’s not too bad,” Vijay added with a nod and motioned, “start it up!”

Binoy ordered his subordinates to start the steam engine.

With the sound of steam blowing through the nozzles, the pistons began to pump, and the gears slowly started to turn. The dynamo, creaking like a beast coming to life, let out a low buzzing sound, though it was mostly drowned out by the roar of the steam engine. Still, Vijay could hear the faint hum the moment it appeared. The engine was running at full power, and Binoy, thrilled, pulled Vijay toward the spot where the wiring was connected.

“Look here, your majesty,” he screamed at the top of his lungs as he brought two wires closer together within an enclosed glass box using glass rods controlled from outside.

As the wires came closer, vague arcs of light began to flow through the wires.

“It’s the electrical discharge from the dynamo, your majesty, it is the current generated from converting the circular motion into electricity by the principle of electromagnetic induction I have discovered.”

“All of these are basically electrons discharged hahaha.”

As the light of the arc reflected off his eyeballs, Vijay was left mesmerised.
