6,600 Volts, an Elephant, and the Dirtiest Tech War in History (Part 1)

⚡ 1903. Film. Elephant. 6,600 volts.

Imagine this: January 1903, Coney Island, New York. A 28-year-old, 5-ton elephant named Topsy – once a circus star – stands on a wooden platform. Copper electrodes are fastened to her feet. A crowd gathers around. Off to the side, a camera from the Edison Manufacturing Company is set up, recording everything that’s about to happen.

6,600 volts of alternating current. Topsy collapses in seconds.

Edison’s company filmed the execution on celluloid. The footage still exists today (you can find it in archives – but be warned, it’s not an easy watch).

Sounds like the plot of a dystopian thriller? Nope, my friend. This is real history. And today, I’m going to tell you how America’s greatest inventor lost his mind trying to destroy his rival’s technology.

And – spoiler alert – why, in 2025, both of them turned out to be right. Why the very device you’re reading this on is powered by the inventions of both geniuses at once.

Ready? Then let’s travel back to 1884…

Chapter 1: Two geniuses enter the ring

Thomas Edison: A shark in human form

Let’s meet the first fighter stepping into our ring.

Thomas Alva Edison (1847–1931). When I first started digging into his story, do you know what struck me the most? Not his 1,093 patents. Not even the light bulb (which, by the way, he didn’t invent – he just made it commercially viable). What really amazed me was how much of a businessman he was inside the body of an inventor.

Picture this: in 1878, Edison founded the Edison Electric Light Company. He was 31 years old and already a celebrity – his phonograph had made him a household name. The press called him “The Wizard of Menlo Park,” and he loved it. He understood the power of publicity long before anyone called it “marketing.” Edison didn’t just sell inventions – he sold himself as a brand.

His vision was simple – and beautiful in its logic. Direct current (DC): safe, stable, predictable. Low voltage – around 110 volts – made it safer for people to use. Edison imagined local power stations in every neighborhood, much like we have gas stations on every corner today.

There’s a quote often attributed to him (though, as with many old legends, the exact source is uncertain): “I shall make electricity so cheap that only the rich will burn candles.”

And you know what? He nearly pulled it off. By the mid-1880s, Lower Manhattan was glowing with electric light powered by Edison’s DC system. It worked. People could literally see the future shining above their streets.

But there was one tiny problem…

Direct current had a fatal flaw: it couldn’t travel far. Imagine this – you generate electricity at a power station, but with every meter of wire, some of it simply disappears as heat. And at the low voltages Edison favored, those losses became enormous. Physics doesn’t negotiate.

In practical terms, that meant you had to build a power station every two kilometers. In a dense city, maybe that was manageable. But for the countryside? Small towns? Forget it. The math just didn’t work.

And here Edison does what all great businessmen do when their technology hits a wall of physics – he pretends the problem doesn’t exist. He doubles down on DC. Builds more power stations. Tells investors that scale will fix everything.

But deep down, he knows: you can’t outsmart physics.

Nikola Tesla: A visionary with a photographic memory

Now let’s meet the second fighter.

Nikola Tesla (1856-1943). A Serb from Austria-Hungary. An emigrant. A stranger in America. And, to be honest, one of the most remarkable personalities in the history of science.

When I read Tesla’s biographies, I often felt like he was a character from a science-fiction novel accidentally dropped into the real world. Judge for yourself:

• Photographic memory: he could recall entire books after reading them once.
• Slept two hours a day: spent the rest of his time working or thinking.

• Obsessed with the number three: walked around a building three times before entering, used 18 napkins at lunch (divisible by three), and lived only in hotel rooms whose numbers were multiples of three.

• Saw his inventions: he claimed he could visualize a device so vividly that it appeared before his eyes in 3D – he could take it apart in his mind and spot its flaws before building anything.

Was he a genius? Undoubtedly. Was he a bit mad? Well… yes, that too.

But the key point is that he had a vision far ahead of his time.

Tesla saw a future where a single powerful power station – say, at a waterfall – could generate electricity and transmit it hundreds of kilometers through wires. No losses. No problems. And this future was made possible by one simple thing: alternating current (AC).

The genius of AC was both simple and brilliant:

The transformer. A simple device with two coils of wire. But it works like magic: it can step up a low voltage to a high one (for long-distance transmission with minimal loss) and then step it back down to a safe voltage (for household use).

With direct current (DC), this is impossible. Transformers just don’t work with DC. Physics strikes again.

Tesla understood this. And he knew the future belonged to AC.

How it all began: Working for Edison (spoiler alert – it ended in disaster)

In 1884, Nikola Tesla, a 28-year-old European immigrant, arrived in New York. He had only a few cents in his pocket, but he carried the designs of his alternating current (AC) motors in his mind – thanks to his photographic memory – and a letter of recommendation for Thomas Edison.

At that time, Edison was already a prominent figure: known as the “Wizard of Menlo Park,” the owner of a successful company, and a millionaire by the age of 37. Tesla, by contrast, was an unknown immigrant with limited English and worn shoes, yet he displayed a clear intensity and focus on ideas.

Edison decided to hire him. The reason was practical: Tesla demonstrated a level of understanding of electrical engineering that surpassed most of Edison’s existing engineers.

Tesla began working on improvements to Edison’s direct current (DC) generators. This period has since become surrounded by anecdotal accounts.

According to one version – whose historical accuracy remains debated – Edison challenged Tesla: “If you can improve my dynamo machines and generators, I will pay you a $50,000 bonus.”

In 1884, $50,000 was roughly equivalent to $1.5 million today. For an impoverished immigrant, this represented a substantial sum with the potential to change his circumstances.

Tesla worked intensively for several months, redesigning 24 different types of Edison’s machines. His modifications made them more efficient, cheaper to produce, and more reliable.

When he reported back to Edison, saying, “It’s done. Your machines have been improved,” Edison allegedly replied, “Tesla, you don’t understand our American humor.”

According to the accounts, the promised bonus was never paid.

The fact remains that in 1885 Tesla left Edison’s company, feeling deceived, undervalued, and slighted.

Historians may debate the details, but the outcome is clear: two talented inventors became rivals.

At this point, a third figure enters the story…

⚡ Chapter 2: The War Begins (and Gets VERY Dirty)

Westinghouse: The Man with Money

In 1886, Tesla was digging trenches in Manhattan. Seriously. The electrical genius, carrying dozens of revolutionary ideas in his mind, earned just $2 a day simply to afford food.

Picture it: Tesla, a well-educated European who spoke eight languages, wielding a pickaxe…

Fate, however, has a way of introducing dramatic turns.

George Westinghouse, an industrialist, inventor of railway brakes, and multimillionaire, heard about an unusual Serbian engineer with groundbreaking ideas about alternating current.

In 1888, Westinghouse purchased Tesla’s patents for AC systems. The exact amount varies according to different sources, but it involved a substantial sum plus royalties. Suddenly, Tesla became wealthy.

More importantly, he gained access to resources, a laboratory, and a team – and, crucially, a powerful adversary in Edison.

Westinghouse didn’t just buy patents; he effectively declared war on DC, and Edison realized the threat.

Imagine being Thomas Edison: you’ve invested millions in DC infrastructure, your power stations operate in dozens of cities, your investors trust you – and suddenly a competitor appears with a technology that could render all your investments obsolete.

What does a businessman do in such a situation?

The answer: he fights. Edison chose to fight – and he did so using methods that would permanently tarnish his reputation.

“The Fear Campaign”: When Scientific Debate Turns into Horror

Now, a warning: what follows is difficult to read, but it is a crucial part of the story.

Edison decided to demonstrate the dangers of AC in the only way he considered effective: through public executions.

Not of people, of course – animals.

Public executions

Between 1880 and the 1890s, Edison and his team – particularly engineer Harold Brown, who was hired specifically for this purpose – began staging public demonstrations of the “dangers of alternating current.”

The method was simple – and brutal:

1. Invite journalists.
2. Take an animal (a dog, a cat, sometimes a horse).
3. Kill it with high-voltage alternating current.

4. Announce: “See? This is what will happen to your children if the city switches to Westinghouse’s system!”

Did it work? Yes. Newspapers reported on the “horrific demonstrations,” people were frightened, and city councils delayed decisions to adopt AC.

The worst part? Edison knew he was manipulating public perception. The danger was not inherent to AC compared to DC – both types of current can be lethal. The real risk depends on voltage and current, not the type of current. Yet Edison deliberately confused these distinctions in the minds of the public.

And the most horrifying episode of this campaign…

Topsy the Elephant

I already mentioned this at the beginning. But let’s dig deeper. 1903, Luna Park, Coney Island. Topsy the elephant was a circus elephant who killed three people during her lifetime (including a trainer who tried to feed her a lit cigarette – yes, people were cruel to animals back then). The park decided to get rid of her. At first, they planned to hang her. Then they considered poison. But someone suggested, “What about electricity?” Edison Manufacturing came to film it. 6,600 volts of alternating current. Topsy died in 10 seconds.

But symbolically, it became the most famous example of that era. And the film still exists in the archives.

I watched it. It was difficult for me. I don’t recommend it.

“Westinghoused” – a term for murder

But Edison did not stop with animals. Another, even more disturbing element of his plan was still in play: the electric chair.

In the 1880s, New York State was seeking a “more humane” method of execution than hanging. Edison and his team actively lobbied for the use of alternating current in the electric chair.

The reasoning was simple and cynical: if AC was used to execute criminals, the public would associate it with death and danger.

On August 6, 1890, William Kemmler became the first person executed by electric chair.

The execution was a disaster. The first discharge – 17 seconds at 1,000 volts – did not kill him. He continued to breathe and groan, leaving witnesses in shock. The voltage was then increased to 2,000 volts for another 72 seconds. There was the smell of burning flesh, and some witnesses fainted. One physician remarked, “This is the most horrible spectacle I have ever seen. Hanging would have been more merciful.”

Edison and his supporters tried to popularize the term “to be Westinghoused” instead of “to be executed by electricity.”

Some newspapers used the term at the time, but it never caught on. People were not fooled – they recognized the manipulation.

The most ironic part? Modern electric chairs (where they are still in use) employ alternating current because it is actually more effective for this grim purpose – not because it is inherently more dangerous, but because the voltage is easier to control.

Tesla’s response: Magic on stage

Imagine Nikola Tesla’s position: his technology was being demonized, his name – through association with Westinghouse – was linked to death, and newspapers warned that his inventions would harm children at home.

Tesla chose to counter this with a dramatic demonstration of AC’s safety: to pass current through his own body. In 1893, at the World’s Columbian Exposition in Chicago – the decade’s largest public event, which drew about 27 million visitors over six months – he staged highly visible demonstrations intended to show that alternating current could be controlled and used safely.

Tesla stepped onto the stage in his pavilion – dressed in an elegant suit, hair neatly combed back, wearing a confident smile – and began a demonstration that left audiences astonished.

He activated his Tesla coil, a device capable of generating high-frequency alternating current with voltages reaching into the millions.

Arcs of electricity jumped between electrodes, filling the air with the smell of ozone. Tesla calmly stood among them, holding light bulbs that glowed as the current passed safely through his body – millions of volts coursing through him, yet causing no harm.

The audience is shocked: “It’s witchcraft! It’s impossible! He’s God!”

But there is a critically important nuance that Tesla did not explain to the audience:

But the audience didn’t understand the technical details. They saw Tesla putting his own life on the line, demonstrating his confidence in the technology.

From a PR perspective, the contrast was striking: Edison had tortured animals to show the dangers of AC; Tesla “tortured” himself to show its safety. Who appeared as the hero, and who as the villain?

Edison and his supporters shouted, “It’s a trick! Manipulation! Deception!” Technically, they were correct – it was a controlled demonstration. But it was undeniably effective.

Niagara Falls: The Decisive Battle

Now comes the main event: the battle for the championship.

In 1893 – the same year as the World’s Columbian Exposition – the New York State Commission announced a competition: who could build a power station at Niagara Falls?

This was the largest contract of the era. Niagara offered a capacity sufficient to power millions. The winner of this contract would effectively control the future of electric power in the United States.

There were two contenders:

• Edison General Electric (DC system)
• Westinghouse Electric (Tesla’s AC system)

The commission spent months reviewing the proposals – engineers, calculations, debates.

Then came the decisive question: “How will you deliver electricity from the falls to the cities?”

Edison’s answer: “We’ll build multiple intermediate stations. It’s expensive, but feasible.”

Westinghouse’s response: “A single high-voltage line directly to the city. Transformers on site will step down the voltage. Simple and cost-effective.”

The commission chose AC.

By 1896, the first line was supplying power to Buffalo – 35 kilometers from the falls.

Thirty-five kilometers. This was impossible with Edison’s DC system. Absolutely impossible.

Nikola Tesla had won.

The reaction of the defeated

Edison publicly acknowledged the defeat. In an interview, he said something along the lines of, “AC has its advantages for long distances. We will continue to develop DC for local networks.”

Translated from PR speak: “Alright, I lost.”

But Edison didn’t sulk. His business kept running. Edison General Electric – later simply General Electric (GE) – continued to generate millions.

And Tesla?

Tesla was already thinking about his next project: wireless power transmission. The Wardenclyffe Tower – intended to provide free electricity to the entire world.

Spoiler: the project failed. But that is another story.

Chapter 3: Final credits (which turned out not to be so final after all)

AC conquers the world (1900-1950)

Fast forward to the early 20th century: AC became the standard. AC power stations were built across America, Europe, and beyond. Transformers appeared on nearly every street corner. High-voltage transmission lines stretched across continents.

DC did not disappear entirely – it remained in specialized applications and local systems. But for main power grids? 99% AC.

It seemed that Tesla had won once and for all. The story appeared complete. The credits were about to roll…

Two endings: Tragedy and triumph

Let’s look at how the lives of the two main figures concluded.

Thomas Edison (died 1931, aged 84)

Edison lived to old age as a millionaire. His company, General Electric, became one of the largest in the world – and still exists today. He was respected, widely known, and held dozens of honorary titles.

In his later interviews, he reflected philosophically: “I have not failed – I’ve just found 10,000 ways that won’t work.” (His famous remark regarding the development of the light bulb.)

He dies surrounded by his family, in his own home, as a successful man.

Nikola Tesla (died 1943, aged 86)

Tesla spent his final years at the New Yorker Hotel, room 3327 (which, of course, divides by three). He was nearly penniless. His patents had made Westinghouse, General Electric, and others wealthy – but not him.

Why? Tesla was a poor businessman. He sold patents for one-time payments instead of royalties, and he invested in ambitious projects that never turned a profit.

In his final years, he fed pigeons in Bryant Park. Seriously. The electrical genius, the man who illuminated the world, feeding crumbs to birds.

He died alone in his hotel room from a coronary thrombosis. His body was discovered two days later.

His last words, recorded by hotel staff: “Money does not matter to a man of science. What matters is what you give to the world.”

Irony of fate

Do you see the irony?

• Edison lost technically, but won financially and socially.
• Tesla won technically, but lost financially and socially.

Who was the true victor? That depends on what you value.

But the story doesn’t end there – because in the 21st century, something happened that no one could have predicted…
