Disturbing History - Tesla's Death Ray

Episode Date: March 15, 2026

In the early nineteen thirties, an aging inventor living alone in a New York City hotel room told the world he'd built a weapon capable of destroying ten thousand enemy aircraft at a distance of two hundred and fifty miles. The press called it a death ray. He called it a peace beam. And the man making the claim wasn't some fringe eccentric chasing headlines. It was Nikola Tesla, the same mind behind the alternating current electrical system that powers the modern world, the same inventor who held over three hundred patents and whose work laid the foundation for radio, radar, robotics, and remote control. When Tesla said he'd built something, history suggested you take him seriously.We trace the full arc of Tesla's extraordinary and tragic life, beginning with his birth in eighteen fifty-six in the village of Smiljan in what is now Croatia. Born into a Serbian Orthodox household, Tesla exhibited vivid sensory experiences from childhood, describing flashes of light and mental images so detailed he could design and test entire machines in his mind without ever touching pencil to paper. The death of his older brother Dane in a riding accident left a lasting mark, fueling a relentless drive to prove himself that would define everything that followed. We follow Tesla through his education at the Austrian Polytechnic in Graz, his pivotal breakthrough in Budapest in eighteen eighty-two when he conceived the rotating magnetic field while walking through a park, and his arrival in New York in eighteen eighty-four with virtually nothing to his name. His brief and bitter employment under Thomas Edison ended with a broken promise and a fury that set the stage for the War of Currents, one of the ugliest chapters in the history of American industry. Edison's campaign to discredit alternating current included the public electrocution of stray animals, the development of the electric chair as a deliberate smear against AC power, and the botched execution of William Kemmler at Auburn Prison in eighteen ninety. Tesla's system won decisively with the illumination of the eighteen ninety-three World's Columbian Exposition in Chicago and the completion of the Adams Power Plant at Niagara Falls, but his victory came at a devastating personal cost when he tore up his royalty agreement with George Westinghouse to save the company from bankruptcy, surrendering a fortune that would have been worth billions today.The episode covers Tesla's groundbreaking experiments in Colorado Springs in eighteen ninety-nine, where he produced the largest man-made lightning bolts in history and claimed to have achieved wireless power transmission over a distance of twenty-five miles. We explore the rise and fall of Wardenclyffe Tower on Long Island, his ambitious plan for a global wireless energy system that was funded and then deliberately killed by J.P. Morgan when Morgan realized the project threatened his copper investments and the very concept of metered electricity.At the heart of the episode is Tesla's proposed teleforce weapon, the so-called death ray. We break down the technical details of what Tesla actually described, a particle beam device that would accelerate microscopic tungsten or mercury pellets to extreme velocities using an open-ended vacuum tube and electrostatic generators producing up to sixty million volts.Tesla shopped the weapon to the United States, Britain, the Soviet Union, and Yugoslavia. The Soviets paid him twenty-five thousand dollars for a preliminary description. The American government turned him down, at least publicly.We also examine Tesla's other inventions and contributions, including the Tesla coil, the first remote-controlled device demonstrated at Madison Square Garden in eighteen ninety-eight, early X-ray imaging, the theoretical groundwork for radar published more than twenty years before its official development, and his eerily accurate nineteen twenty-six prediction of pocket-sized wireless devices that would allow people to communicate, access information, and transmit images across the globe.Alongside these genuine achievements, we address the claims that haven't held up, including thought photography, the earthquake machine, and his belief that he'd received radio signals from extraterrestrial intelligence.The final act of the episode covers Tesla's lonely last years at the Hotel New Yorker, his obsessive devotion to the pigeons of New York City, and his death on January seventh, nineteen forty-three, alone in room thirty-three twenty-seven. Within hours, the Office of Alien Property seized his papers under legally questionable authority despite Tesla's status as a naturalized American citizen. MIT physicist John G. Trump evaluated the materials in roughly three days and declared them of no significant value, a conclusion that many researchers have found unconvincing given the volume of material and the government's continued classification of the documents for years afterward. Tesla's nephew Sava Kosanovic reported that key documents appeared to be missing, and declassified FBI files confirm the Bureau had been monitoring Tesla for years and considered his weapon claims potentially significant. The episode also explores the persistent questions around what was actually in those eighty to one hundred and fifty trunks, the fate of Tesla's technical treatise on the teleforce weapon, the parallels between his particle beam concept and Cold War weapons programs pursued by both the United States and the Soviet Union, and the possibility that the full contents of his seized research have never been made public.Have a forgotten historical mystery, disturbing event, unsolved crime, or hidden conspiracy you think deserves investigation?Send your suggestions to [e-mail] History is a dark history podcast exploring unsolved mysteries, secret societies, historical conspiracies, lost civilizations, and the shadowy stories buried beneath the surface of the past.Follow the show and enable automatic downloads so you never miss a deep dive into history’s most unsettling secrets.Because sometimes the truth is darker than fiction.

Investigator, author, and your government. guide through the dark corners of our collective memory. Each week, I'll narrate some of the most chilling and little-known tales from history

that will make you question everything you thought you knew. And here's the twist. Sometimes, the history is disturbing to us. And sometimes, we have to disturb history itself, just to get to the truth. If you like your facts with the side of fear, if you're not afraid to pull at threads, others leave alone. You're in the right place. History isn't just written by the victors.

Sometimes, it's rewritten by the disturbed. There's a photograph you've probably seen before. Maybe it was in a history textbook, or pinned to somebody's wall in a college dorm room, or floating around the internet the way old photographs tend to do when they've outlived the people in them. It shows a thin man sitting calmly in a chair, legs crossed,

reading a book by the light of enormous artificial lightning bolts that crack and sizzle just a few. few feet from his body. Millions of volts of electricity arcing through the air around him like the fingers of an angry god. And this man, this gaunt figure with the sharp cheekbones and the dark, deep-set eyes, he doesn't even flinch. He just sits there, reading. That man was Nikola Tesla. And that photograph, while somewhat staged for publicity purposes, tells you everything you need to know about who he was. He was a man who sat comfortably inside the storm. a man who claimed he could split the earth in two.

A man who said he'd built a weapon that could bring down 10,000 enemy aircraft at a distance of 250 miles and render any nation on earth absolutely impervious to attack. He called it a peace bean. The newspapers called it something else. They called it a death ray. Now I know what you're thinking. Death rays belong in science fiction movies and comic books, not on a show about real history.

And you'd be right to think that, except for one uncomfortable little detail. The man making this claim wasn't some crackpot working out of his garage. This was Nikola Tesla. The same Nikola Tesla who'd invented the alternating current electrical system that powers virtually every home and business on the planet today. The same Tesla who'd invented radio technology before Marconi ever got credit for it. The same Tesla who held over 300 patents across 26 countries

and whose work formed the foundation of modern electrical engineering, robotics, radar, x-ray technology, and remote control. When Nikola Tesla told you he'd built something, history had taught the world that maybe you ought to listen. And that's exactly why this story belongs on disturbing history. Because what happened to Nikola Tesla at the end of his life, what happened to his papers, his research, his plans for this alleged super weapon.

That's not just a story. about a brilliant inventor who died alone in a hotel room. It's a story about government secrecy, wartime paranoia, stolen documents, and the very real possibility that one of the most dangerous weapons ever conceived was either buried, destroyed, or quietly handed off to people who had no intention of using it for peace. Tonight, we're going back to the very beginning.

We're going to trace the life of a man who was born during a lightning storm and died in the dark, a man who lit up the world and got almost nothing in return, and we're going to ask the question that's haunted researchers and conspiracy theorists alike for more than 80 years now. What happened to Tesla's death ray? Let's find out. To understand who Nikola Tesla became, you've got to understand where he came from.

And where he came from was about as far from the gleaming laboratories of New York City as you could possibly get. Nicola Tesla was born on July 10, 1856, in the village of Smiljan, which at the time was part of the Austrian Empire and is located in what we now know as Croatia. His father, Malutin Tesla, was a Serbian Orthodox priest and a writer. His mother, Jukamandik, was the daughter of a Serbian Orthodox priest herself. So right away, you've got a household steeped in religion, in tradition, in the kind of rigid structure that doesn't exactly encourage. a child to go around telling people he can see visions of light and hear things nobody else can hear. But that's exactly what young Nicola did. From his earliest years, Tesla exhibited what

modern psychologists might recognize as extraordinarily vivid sensory experiences. He described seeing flashes of light that would appear before his eyes, sometimes accompanied by visions of objects and scenes so real, so detailed, that he had difficulty distinguishing them from actual physical reality. He wrote about this extensively later in life, and he was remarkably candid about it. He didn't try to dress it up as some kind of mystical gift. He described it almost clinically, as a condition he'd learned to manage over time. And here's where it gets interesting. Tesla claimed that these vivid mental images weren't just random hallucinations. He said he could use them. He said he'd developed the ability to visualize complete machines in his mind, down to the smallest, completely

and that he could mentally operate those machines, test them, identify flaws, and make adjustments, all without ever putting pencil to paper or building a single physical prototype. He called this his mental laboratory, and he insisted it was just as real and just as reliable as any physical workshop. Now whether you believe that or not is up to you. But consider this. The man went on to invent some of the most complex electrical systems in human history. history. And multiple accounts from people who worked with him confirmed that he rarely used detailed blueprints. He'd work out the entire design in his head, dictate the specifications,

and the machines would work. Not always on the first try, sure, but often enough that even his rivals had to admit there was something genuinely extraordinary about the way his mind operated. Tesla's childhood wasn't easy, though. His older brother Dane, who was widely considered the more gifted of the two boys, died in a whole. horse riding accident when Nicola was about five years old. Some accounts suggest the horse through Dane. Others suggest there may have been more to it. Tesla himself offered conflicting accounts over the years, and at least one version he told, suggested he might have inadvertently startled the horse. Whatever actually happened, Dane's death cast a long shadow over the

Tesla household, and young Nicola spent much of his childhood, feeling like he was living in his dead brother's shadow, constantly trying to prove to his parents that he was worthy of their attention and love. It's a detail that might seem small, but it matters, because that relentless need to prove himself, that burning drive to accomplish something so extraordinary that nobody could possibly overlook him. That became the engine that powered Tesla's entire life. And it's the same engine that would eventually drive him to make claims so grand, so seemingly impossible, that the world would stop listening right when it should have been paying the closest attention. Tesla was a sickly child in many respects. He suffered from a variety of ailments throughout his youth,

and he developed what he described as peculiar afflictions and compulsions. He had an extreme sensitivity to sound. He said the ticking of a watch three rooms away sounded like the pounding of a hammer to him. He couldn't bear to touch other people's hair. He was repulsed by pearls and by earrings. He had an obsessive need to calculate the cubic volume of his food before he could eat it, and he required that the number of napkins at his place setting be divisible by three. These aren't things people made up after the fact to add color to his biography. Tesla wrote about them himself. And while it's impossible to retroactively diagnose someone who's been dead for more than 80 years,

many modern researchers and biographers have noted that his symptoms are remarkably consistent with what we'd now call obsessive compulsive disorder. Some have also suggested he may have been somewhere on the autism spectrum, though that's more speculative. What's not speculative is that his mind worked differently from other people's minds. And that difference, that ability to see the world in ways nobody else could, it was both his greatest gift and eventually his greatest curse. As a young man, Tesla was a brilliant student with an almost supernatural ability

to perform complex mathematical calculations in his head. He attended the Austrian polytechnic in Graz on a military frontier scholarship, and during his first year he reportedly never missed a lecture, earned the highest possible grades in every subject, and even received a letter of commendation from the dean of the technical faculty to his father, praising Nicola as a star of first rank. But things went sideways during his second and third years. Tesla became obsessed with gambling,

particularly card games, and his academic performance suffered dramatically. He also became increasingly consumed with the problem that would define his early career, the limitations of direct current electricity, and the tantalizing possibility of alternating current. See, at the time, the dominant form of electrical power was direct current, or DC, and the man championing DC power was none other than Thomas Alva Edison, who by the early 1880s was already well on his way to becoming the most famous inventor in the world. Edison had built his entire empire on direct current, and he had no intention of seeing it replaced. But direct current had a fundamental problem.

It couldn't travel very far. DC power plants had to be built every mile or so, which made electrifying anything beyond a small urban area, enormously expensive and logistically impractical. Tesla knew there had to be a better way, and the better way he was convinced was alternating current, a system in which the electrical current periodically reversed direction, allowing power to be transmitted over vastly greater distances with far less energy loss. The idea had been floating around in theoretical circles,

but nobody had figured out a practical way to make it work. Specifically, nobody had solved the problem of the AC motor. You needed a motor that could run on alternate. alternating current, and every design anyone had come up with required something called a commutator, a mechanical component that introduced friction, sparking, and constant maintenance. Tesla was convinced there was a way to build an AC motor without a commutator, and he was right. The breakthrough came in 1882 while Tesla was walking through a park in Budapest with a friend. He'd been reciting poetry, Good as Faust of all things, when the vision hit him.

He described it as a flash of insight so vivid and so complete that he immediately knelt down and used a stick to draw a diagram in the dirt. What he drew was the rotating magnetic field, the principle that would make the alternating current induction motor possible. No commutator, no brushes, no sparking, just smooth, efficient, endlessly rotating magnetic fields that could power a motor cleanly and reliably. It was, by any reasonable measure, one of the most important. important technological breakthroughs of the 19th century, and Tesla had figured it out while taking a walk in the park. In 1884, at the age of 28, Tesla immigrated to the United States with almost nothing to his name. The story goes that he arrived in New York City with four cents in his pocket, a book of his own poetry, a few articles of clothing, and a letter of introduction

to Thomas Edison written by Charles Batchelor, one of Edison's associates in Europe. The letter allegedly read, I know two great men and you are one of them. The other is this young man. Whether that letter actually existed and whether those were the actual words is a matter of some historical debate. But what's not debatable is that Tesla went to work for Edison almost immediately upon arriving in New York.

And the relationship between these two men, these two towering figures of electrical engineering, would become one of the most famous and most bitter rivalries in the history of science. Tesla went to work at Edison's laboratory on the lower east side of Manhattan, and by all accounts, he was a phenomenal worker. He put in 18-hour days. He solved problems that had stumped Edison's other engineers. And at some point, according to Tesla's own account, Edison made him a promise. Tesla claimed that Edison told him if he could redesign Edison's direct current generators

to make them significantly more efficient. Edison would pay him $50,000. Now, $50,000. Now, $50,000 in 1884 would be roughly equivalent to about $1.5 million today. It was an enormous sum. Tesla went to work. He spent months redesigning Edison's generators, and by his own account, he succeeded brilliantly. He improved the efficiency of the machines, designed new automatic controls, and delivered exactly what Edison had asked for. And then he asked for his $50,000.

Edison laughed at him. Tesla, Edison reportedly said, you don't understand our American humor. Now, I want to be fair here. Edison's side of this story is less well documented, and some historians have questioned whether the $50,000 promise was ever explicitly made, or whether Tesla may have misunderstood a joke or an offhand comment.

We don't know for certain. What we do know is that Tesla felt he'd been cheated, and he quit Edison's laboratory in a fury. That moment, that bitter parting of ways, set the stage for what would become known as the War of Currents, one of the ugliest and most consequential technological battles in American history. After leaving Edison, Tesla went through a rough patch. He took a job digging ditches for the Edison Company, of all things, just to survive. But he eventually found backers who helped him establish the Tesla Electric Company, and he began filing patents for his alternating current

system, including the polyphase AC motor, the transformer, and the complete system for generating, transmitting, and utilizing alternating current power. Stay tuned for more disturbing history.

These patents caught the attention of George Westinghouse, a wealthy industrialist and inventor who'd made his fortune developing the railway airbreak. Westinghouse immediately recognized the revolutionary potential of Tesla's AC system, and in 1888 he purchased Tesla's AC patents for $60,000 in cash, plus stock in Westinghouse Electric, plus a royalty of two. dollars and fifty cents per horsepower of AC electricity sold. That royalty agreement, had it been

honored in full, would have eventually made Nikola Tesla one of the richest men on the planet. Remember that detail. It becomes important later. With Westinghouse's money and infrastructure behind him, Tesla's alternating current system went head to head with Edison's direct current. And Edison did not take the competition gracefully. What followed was one of the most disturbing episodes in the history of corporate warfare. And frankly, it's one of the reasons this story belongs on this show. Edison, desperate to prove that alternating current was dangerous, launched what can only be described as a campaign of calculated terror against the American public. He hired a man named Harold P. Brown, an electrical engineer who may or may not have been

on Edison's official payroll, but was certainly acting in Edison's interests. Brown began conducting public demonstrations in which he electrocuted stray dogs and cats using alternating current. These were grotesque spectacles. Brown would invite reporters and members of the public to watch as he subjected animals to lethal doses of AC electricity, all while carefully noting that direct current Edison's preferred system was far safer. The demonstrations were widely covered in the press, and they had exactly the effect Edison intended. People were terrified. People were terrified. Mothers wrote letters to newspapers demanding that alternating current be banned. Politicians introduced legislation to limit AC voltage.

The fear was real, even though the science behind it was deliberately misleading. Any electrical current, whether AC or DC, can be lethal at sufficient voltage. Edison knew that. He didn't care. The point wasn't science. The point was fear. Edison and his associates also played a pivotal role in the development of the electric chair. When the state of New York was looking for a more humane method of execution than hanging,

Edison's camp lobbied hard to ensure the new device would run on alternating current. The reasoning was cynical, but effective. If the public associated AC power with the instrument of death row, they'd never accepted in their homes. Edison even reportedly tried to popularize the term Westinghouse as a synonym for electrocution, as in, the condemned man was Westingham. house this morning. It didn't catch on, but the fact that he tried tells you everything you need to know about how far he was willing to go. The first person executed by electric chair was William Kimler on August 6, 1890 at Auburn Prison in New York. The execution was, by all accounts, a horrific disaster. The first jolt of current didn't kill Kimler. He was still breathing, still groaning.

The executioners had to administer a second longer jolt, during which, witnesses reported the smell of burning flesh and visible singeing of Kimmer's skin. George Westinghouse, upon hearing the news, said simply, they could have done it better with an axe. And then there was Topsy. In January of 1903, a 36-year-old circus elephant named Topsy was publicly electrocuted at Luna Park in Coney Island. Topsie had killed three men over a period of several years, including an abusive handler who'd fed her a lit cigarette, and the owners of Luna Park had decided she needed to be put down.

The execution was filmed by the Edison Manufacturing Company, and the footage was distributed as a short film. Now it should be noted that some historians debate the degree of Edison's direct personal involvement in the Topsy incident. By 1903, the War of Currants was largely over, and Edison had moved on to other ventures. But his company filmed it. His name was attached to it, and the event has become one of the most infamous symbols of the lengths to which Edison's side was willing to go in the fight against alternating current.

It was propaganda. It was fear-mongering. It was animal cruelty deployed as corporate strategy. And for a while it worked. But the truth was on Tesla's side. Alternating current was simply better technology. It could travel farther. It was more efficient. And it was more practical for large-scale electrification. The decisive victory came in 1893 when Westinghouse used using Tesla's AC system, won the contract to illuminate the world's Colombian exposition in Chicago. The fair dazzled visitors with its 200,000 electric lights,

and it proved once and for all that alternating current was the future of electrical power. Two years later, Tesla and Westinghouse completed the Adams Power Plant at Niagara Falls, the first large-scale AC power plant in the world. It transmitted electricity over 20 miles to the city of Buffalo, New York, And it worked flawlessly.

The war of currents was over. Tesla had won. But here's the part of the story that most people don't know. And it's one of the most heartbreaking details in the entire history of American innovation. By the mid-1890s, Westinghouse Electric was in serious financial trouble. The company had overextended itself, and its creditors were circling. George Westinghouse went to Tesla and explained the situation. He told Tesla that the royalty agreement, those $2.50,000,000,000,000,000,000,000,000,000

50 cents per horsepower was going to bankrupt the company. He asked Tesla to tear up the contract, and Tesla did it. He literally ripped up the royalty agreement. He surrendered what would have eventually been worth hundreds of millions of dollars, possibly billions in today's money, because he believed in Westinghouse, because he felt a loyalty to the man who'd believed in him, and because he genuinely thought the widespread adoption of AC power was more important than his own personal fortune.

It was an act of extraordinary generosity. It was also arguably the worst financial decision in the history of invention. Because from that moment forward, Nikola Tesla would never be financially secure again. The man who'd given the world its electrical grid would spend the last decades of his life borrowing money, dodging creditors, and moving from one hotel to another when he couldn't pay his bills. But we're getting ahead of ourselves. because Tesla's AC system, as revolutionary as it was, was just the beginning. The man had ideas that made alternating current look like a warm-up act.

After the triumph at Niagara Falls, Tesla turned his attention to what he believed was the next great frontier of electrical science, wireless transmission of energy. Not wireless communication, mind you, though Tesla was working on that too. He was talking about transmitting actual electrical power through the air. or more specifically through the earth itself, without wires. He envisioned a world in which electricity would be available everywhere, to everyone, all the time, transmitted from central towers that would beam energy across continents.

No power lines, no meters, no monthly bills, just free unlimited energy for all of humanity. If that sounds too good to be true, well, that's because it was. Or at least, it was too good to be profitable. which in the world of American capitalism amounts to pretty much the same thing. But Tesla was dead serious about it, and in 1890, he set up a laboratory in Colorado Springs, Colorado, to conduct experiments in wireless energy transmission. And what happened in that laboratory over the next several months was absolutely extraordinary.

Tesla built a massive device called a magnifying transmitter, essentially a giant Tesla coil capable of producing millions of volts of electrical energy. energy. He used it to create artificial lightning bolts more than 130 feet long, which remained the largest man-made electrical discharges in history. The thunder from these experiments could be heard 15 miles away. He accidentally burned out the generator at the local power company and plunged the entire town of Colorado Springs into darkness. And he claimed, controversially, that he'd successfully transmitted electrical energy without wires to light up a bank of 200 incandescent lamps at a distance of 25 miles.

That last claim has been hotly debated ever since. Some researchers believe Tesla may have exaggerated his results or misinterpreted his data. Others believe he genuinely achieved wireless power transmission over a limited distance, but overstated its practical implications. And a few Tesla enthusiasts believe he succeeded completely, and that his results were deliberately suppressed by powerful financial interests who couldn't allow free energy to disrupt their business models. The truth is probably somewhere in the middle.

Tesla was an extraordinary scientist, but he was also a showman, and he had a tendency, particularly later in life, to make claims that outran his evidence. But there's no question that the Colorado Springs experiments produced genuinely remarkable results, and they convinced Tesla that his vision of worldwide wireless energy was achievable. Buoyed by his Colorado Springs experiments, Tesla returned to New York and began work on the project that he believed would be his crowning achievement.

Wardencliff Tower. Located in Shoreham, Long Island, Wardencliff was supposed to be the first node in a global wireless transmission system. Tesla purchased 200 acres of land and hired the renowned architect Stanford White to design the main laboratory building. White produced a handsome brick structure that still stands today, though it's been repurposed many times since Tesla's day. But the real centerpiece of the project was the tower itself, a massive wooden frame structure about 187 feet tall, topped with a distinctive mushroom-shaped copper dome that was 55 feet in diameter. It looked like something from a science fiction novel, and in a sense, it was.

Because what Tesla intended to do with it was so far ahead of its time that even his own financial backers couldn't fully comprehend it. Beneath the tower, a complex system of iron pipes extended 120 feet down into the Earth. Tesla's plan was to use the tower to transmit both wireless communications and wireless electrical power across the Atlantic Ocean. The underground root system, as Tesla called it, was designed to couple the tower's energy directly into the Earth, using the planet itself as a conductor. In Tesla's conception, the Earth was not just a lump of rock floating in space.

It was a vast, resonant electrical body that could be made to vibrate at specific frequencies, and those vibrations could carry energy to any point on the globe. It was audacious, it was visionary, and it was in the eyes of the men who controlled the money, utterly terrifying. The project was funded initially by J.P. Morgan, one of the most powerful financiers in American history. Morgan put up $150,000, which was an enormous sum at the time, and Tesla began construction. But there was a problem. Tesla had originally pitched the project to Morgan as a wireless communication system,

essentially a more powerful version of Marconi's radio technology. What Tesla actually intended to build was something far more ambitious, a system for transmitting free electrical power to the entire world. And when Morgan figured out what Tesla was really up to, he was not happy. Think about it from Morgan's perspective. J.P. Morgan had massive investments in the copper industry. Copper was essential for electrical wiring. If Tesla's system worked, if electricity could be transmitted without wires,

the demand for copper would plummet. Morgan's investments would be worthless. And beyond that, there was the fundamental business problem. If electricity was free and available everywhere, how exactly would anyone make money from it? Morgan pulled his funding, and he didn't just stop writing checks. According to multiple historical accounts, Morgan actively worked to ensure that no other investor would fund Wardenclyffe either. Tesla begged, he pleaded, he wrote desperate letters, but the money never came.

Wardencliff Tower was never completed, and in 1917, the unfinished structure was demolished and sold for scrap to help pay Tesla's debts. The demolition of Wardencliff marked a turning point in Tesla's life. He was 59 years old. was broke. His greatest dream had been destroyed, and while he'd continue to work and to file patents and to make public statements about his research for another 25 years, there's a sense in the historical record that something fundamental broke inside him when that tower came down. It was around this time that Tesla began making increasingly grandiose claims about inventions he'd supposedly developed, or was in the process of developing. Some of these claims were grounded in legitimate science.

Others were more speculative, and a few were so outlandish that they caused even his most devoted supporters to wonder whether the great inventor was losing his grip on reality. He claimed to have developed a method for photographing thoughts, arguing that a retinal image formed in the mind could theoretically be captured and projected onto a screen. He talked about building a machine that could produce earthquakes on demand, and there's actually a kernel of truth to this one. Tesla had indeed experimented with mechanical oscillators, and he claimed that one of his devices had nearly shaken his laboratory apart and caused a minor panic in the surrounding neighborhood.

He told the story of attaching a small oscillator to a steel beam and gradually tuning it until the beam began to vibrate with increasing violence, at which point he said he had to smash the device with a sledgehammer before it brought the building down. Tesla later claimed that the same principle applied on a larger scale, could theoretically be used to split the earth itself. He was joking, probably. Stay tuned for more disturbing history.

Sprinker, because if you're going to talk to yourself for an hour, you might as well publish it. He also claimed to have received radio signals from extraterrestrial beings. In 1890, while working in his Colorado Springs Laboratory,

Tesla detected unusual repetitive signals on his receiver that he couldn't attribute to any known terrestrial source. He became convinced that these signals were communications from intelligent life on another planet, most likely Mars. He wrote about this publicly, and it generated enormous public interest, along with a fair amount of ridicule. Modern scientists have suggested that what Tesla actually picked up was probably radiation from Jupiter's magnetosphere, or possibly signals from one of Marconi's early wireless experiments.

But Tesla went to his grave believing he'd made contact with alien intelligence. Now, some of these claims were clearly ahead of their time. Others were probably wrong. And it's important to be honest about the fact that as Tesla aged, the line between his genuine innovations and his unsupported speculations became became increasingly blurry. His supporters tend to treat everything he ever said as gospel truth. His detractors tend to dismiss his later work as the ramblings of a man in decline. The reality, as usual, is more complicated, because in among all the wild claims and the unfunded proposals and the increasingly desperate pleas for attention and support,

there was one idea that stood out from all the rest. One idea that was so alarming, so potentially world-changing and so disturbingly plausible that it caught the attention of governments around the globe. The Death Ray. Tesla first began talking publicly about his particle beam weapon in the early 1930s when he was already in his 70s. He gave interviews. He wrote letters to government officials. He published a detailed technical paper. And what he described was not some vague, hand-wavy science fiction fantasy. It was a specific, technically detailed proposal for a weapon unlike anything the world had ever seen.

Tesla called it a teleforce weapon, though he also sometimes referred to it as his peace beam. Because he believed, sincerely believed, that a weapon powerful enough to destroy any invading army or air fleet would make war itself obsolete. If every nation possessed such a weapon, he argued, no nation would dare attack another. It was the same logic that would later be applied to nuclear weapons, the idea of mutually assured destruction. Except Tesla was proposing it more than a decade before the atomic bomb was even a theoretical possibility. So what exactly was this weapon? How was it supposed to work?

Tesla described a device that would accelerate microscopic particles. He usually specified tiny pellets of tungsten or mercury to enormous velocities using a combination of high voltage and an open-ended vacuum. vacuum tube. These particles would be propelled at speeds he estimated at roughly 48 times the speed of sound, and they would travel in a concentrated beam over distances of up to 250 miles. Anything caught in the path of this beam, an airplane, a tank, an army, would be instantly destroyed. Let's break that down a little bit, because the technical details matter, and they're the reason this isn't just another crackpot claim from a man in decline. There was real science behind what Tesla was proposing, even if the engineering challenges were and remain enormous.

First, the vacuum tube. This is the part Tesla considered his most critical innovation. Conventional vacuum tubes at the time required sealed ends. You'd pump the air out, seal the tube, and use it to accelerate electrons or other particles within that controlled environment. But a sealed tube has an obvious limitation. The particles can't get out. You can accelerate them all you want inside the tube. But the moment they hit the sealed end, the energy goes nowhere useful. For a weapon, you need the particles to exit the tube and travel through open air toward a target. Tesla claimed to have invented what he described as an open-ended vacuum tube, a tube that could maintain a near perfect vacuum at one end while allowing accelerated particles

to exit freely at the other. He said this was achieved through a combination of high-velocity gas jets that created a sort of aerodynamic seal at the open end of the tube. In other words, instead of a physical barrier, he used the physics of moving gas to keep the air out while letting the particles through. This sounds exotic, but it's not entirely without scientific basis. Modern particle accelerators use a variety of techniques to manage the interface between vacuum environments and open air, including differential pumping systems that achieve something conceptually similar to what Tesla described. Whether Tesla actually solved this problem in the 1930s,

with the technology available to him at the time, is another question entirely. But the concept itself isn't crazy. Second, the power source. Tesla proposed using one of his large Van de Graf-style electrostatic generators to produce the enormous voltages needed to accelerate the particles. He talked about potentials in the range of 50 to 60 million volts, which was far beyond anything that existed at the time, but wasn't theoretically impossible. Modern particle accelerators routinely achieve voltages in this range and far beyond. The large Hadron Collider at CERN, for instance, accelerates particles to energy's equivalent to trillions of electron volts. Tesla was thinking along the right lines, even if the scale of what he proposed

was beyond the engineering capabilities of his era. Third, the beam itself. Tesla was very specific about the fact that this was not a ray in the traditional sense. He objected strongly to the term death ray, and he got visibly irritated when reporters used it. He said his device didn't project energy in the form of light or electromagnetic radiation.

It projected matter, actual physical particles, at extremely high velocities. The distinction matters, because it puts Tesla's proposal into a different scientific category than the ray guns of pulp fiction. In modern terminology, what Tesla described is much closer to a particle beam weapon than to a laser or a directed energy weapon. And particle beam weapons are a real thing.

They're not science fiction. The United States, Russia, and other nations have spent billions of dollars researching them over the decades. Tesla was, once again, ahead of his time. In 1934, on his 78th birthday, Tesla gave a widely reported interview in which he described the weapon in detail. He told reporters that the beam could bring down a fleet of 10,000 enemy aircraft at a distance of 250 miles from a defending nation's borders, and that it would provide an invisible wall of defense that no attacking force could penetrate. He said the device would cost no more than $2 million to build and could be operational within three months. He also said he'd offered the weapon to the United States government, and that the United States government had turned him down.

Now, this is where things get murky, and it's important to separate what we know from what we think we know and from what people have speculated about over the years. What we know is that Tesla did approach multiple governments with his particle beam weapon proposal. He contacted the United States War Department. He contacted the British government. He contacted the Soviet Union. and he contacted the kingdom of Yugoslavia. He was shopping this weapon to anyone who would listen, and his stated motivation was always the same.

He wanted to prevent war. What we also know is that at least one government appears to have taken him seriously. There are documented records indicating that in 1935, Tesla negotiated with the Soviet government's Amtorg Trading Corporation, which served as a purchasing agent for the Soviet Union in the United States. According to Tesla's own papers and corroborating records, the Soviets paid Tesla $25,000 for a preliminary description of the weapon. Whether they received anything of genuine value for their money is unclear. The United States government's response to Tesla's proposal is less well documented and considerably more controversial.

The official line, based on what little has been declassified, is that the War Department looked into Tesla's claims and determined that the weapon was not. practical. But there are a lot of people who don't buy that explanation, and they point to what happened after Tesla's death as evidence that the government took his work far more seriously than it ever publicly admitted. But we'll get to that. Before we talk about Tesla's death, we need to talk about the last decade of his life, because it's one of the saddest chapters in the entire history of science. By the 1930s, Tesla was living in a series of increasingly modest hotel rooms in New York City. He had no permanent home. He had very little money. He survived primarily on a small monthly stipend provided by the Westinghouse Corporation, which had never entirely

forgotten the man who'd built the foundation of their empire, even if they hadn't compensated him fairly for it. The stipend covered his room at the Hotel New Yorker, where he lived in rooms 3327 and 3328 on the 33rd floor. He'd specifically requested the 33rd floor, and the 33rd floor because the room number was divisible by three. His obsessive compulsions hadn't faded with age. If anything, they'd intensified. Tesla's daily routine during these final years was remarkably consistent and in its own way, deeply poignant. He'd wake up, dress impeccably in a suit and tie. He was always immaculately dressed even when he couldn't afford to eat properly, and he'd walk to Bryant Park or sometimes to the steps of the New York Public Library to feed the pigeons.

Not just any pigeons. Tesla had developed an intense emotional attachment to the pigeons of New York City, and to one pigeon in particular, a white female pigeon with light gray tips on her wings that he described as the love of his life. He reportedly told friends that this pigeon visited him at his hotel window every day, and that he loved her as a man loves a woman. He said that as long as he had the pigeon, he had a purpose.

He would sometimes bring injured pigeons back to his hotel room, room to nurse them, and he reportedly spent thousands of dollars on veterinary care for his birds, money he could barely afford. When his beloved white pigeon fell ill, Tesla devoted himself to her care with an intensity that alarmed the few friends he had left. And when she died, Tesla said, something went out of him that he couldn't get back. He told one associate that when the pigeon died, a powerful light that had always been present in his life went out, and he knew his own life's work was finished. Now, it would be easy to be cruel about this. It would be easy to point to the pigeon obsession and the hotel rooms and the compulsions and say that Tesla had simply gone

mad. And some biographers have done exactly that. But there's a more generous reading of the situation, and I think it's the more honest one. Tesla was alone. He'd never married. He'd never had children. He'd devoted his entire life to his work, and his work had been stolen from him, undermined by rivals, abandoned by investors, and forgotten by the public. He was in his 80s, living in a hotel room, and the pigeons were the only creatures on Earth who came to see him every day without wanting something. I don't think that's madness. I think that's loneliness. And there's a difference. Despite his diminished circumstances, Tesla continued to work. He continued to think, and he continued to make public statements about his inventions, including the particle beam weapon.

Every year on his birthday, he'd hold a small press conference, and the reporters would come, partly out of genuine interest and partly because Tesla's birthday pronouncements had become something of a New York tradition. He'd announced new inventions, make predictions about the future, and occasionally drop a bombshell that would generate headlines. In 1937, at the age of 81, Tesla was struck by a taxi cab while crossing a street near the New York Public Library. The accident broke several of his ribs and severely injured his back. He refused to see a doctor, which was consistent with his lifelong aversion to medical treatment, and he never fully recovered.

The accident left him weakened, and his health declined steadily over the next several years. During these final years, Tesla became increasingly reclusive. He rarely left his hotel room. He stopped holding his birthday press conferences. He communicated primarily through letters and occasional phone calls, but he never stopped working. His mind, by all accounts, remained sharp even as his body failed. And he continued to claim that he possessed the plans for weapons and inventions of extraordinary power, plans that he kept locked away in his hotel room and in his own remarkable memory.

And this is where we get to the end, the end of Tesla's life, and the beginning of one of the most enduring mysteries of the 20th century. On January 7, 1943, Nicola Tesla died alone in his room at the Hotel New Yorker. He was 86 years old. The cause of death was coronary thrombosis, a blood clot in the heart. His body was discovered by a hotel maid named Alice Monaghan, who entered his room despite the do-not-disturb sign that Tesla had hung on his door two days earlier.

She later said she'd had a feeling that something was wrong. She'd ignored the sign before when she worried about him, and this time her worry was justified. Tesla was lying in his bed, thin as a rail and fully dressed. His arms crossed over his chest as though he'd arranged himself for his own funeral. He'd been dead, the coroner estimated, for roughly two days, two days during which nobody came looking for him, two days during which nobody noticed that one of the greatest minds

in human history had gone silent. The man who'd invented the electrical system that powered the entire Hotel New Yorker died in that very building, and it took 48 hours for anyone to notice. And here's where things get strange. Very strange. Within hours of the discovery of Tesla's body, before his family had even been notified, before any kind of proper inventory could be conducted, agents from the United States government descended on the Hotel New Yorker and seized Tesla's personal effects, his papers, his notebooks, his files, everything. Stay tuned for more disturbing history. We'll be back after these messages.

Now the agency that took Tesla's belongings was the Office of Alien Property, or OAP, which operated under the authority of the alien property custodian. The stated justification for the seizure was that Tesla was a foreign national, technically true as he was born in the Austrian Empire and had been a citizen of Yugoslavia, even though he'd lived in the United States for nearly 60 years and had become a naturalized American citizen in 1891. The claim that the OAP had legitimate jurisdiction over the property of a naturalized American citizen is legally

questionable at best, but it happened, and it happened fast. The speed of the government's response has fueled decades of speculation. How did they know? How did they get there so quickly? And why was the Office of Alien Property, rather than a military or intelligence agency, the one to take custody of the materials. Some researchers have suggested that Tesla's hotel room was under surveillance in the weeks or months before his death, and that the government had a plan already in place to seize his papers the moment he died. Others believe it was simply bureaucratic overreach in a time of war, as the country was deep in the middle of World War II, and the government was understandably paranoid about enemy nations gaining access to potentially dangerous technology. What we know for certain is that

the government seized a substantial quantity of material. Various accounts put the number at somewhere between 80 and 150 trunks and boxes, depending on which source you trust. This material included scientific papers, notebooks, correspondence, personal effects, and according to some accounts, working models or components of devices Tesla had been building. The government brought in a team to evaluate the seized material, and here's where a very important name enters the story. John G. Trump. Yes, that Trump. John George Trump was the uncle of Donald J. Trump, the 45th president of the United States. But in 1943, John Trump was a highly respected electrical engineer and physicist at the Massachusetts Institute of Technology. He was a member of the National Defense Research Committee and an expert on high-voltage equipment and Van de Groff generators,

which made him arguably the most qualified person in the country to evaluate Tesla's particle beam weapon claims. Trump spent approximately three days reviewing Tesla's papers. When he was done, he issued a report, and his report was, to put it mildly, dismissive. He concluded that Tesla's papers did not contain any new, practical, or workable principles or methods for realizing such results. He said the material consisted primarily of general philosophical commentary, expressions of appreciation, and articles already published. In other words, according to John Trump, there was nothing there, no death ray plans, no revolutionary weapons technology,

nothing the government needed to worry about. And that was the official story. Case closed. Tesla was a brilliant man who'd made some important inventions early in his career, but had spent his later years making grand claims he couldn't back up. The death ray was a fantasy. The papers were worthless. Move along.

Nothing to see here. Except a lot of people didn't buy it. And they had some pretty good reasons not to. First, there's the question of time. John Trump spent approximately three days reviewing material that had taken Tesla decades to produce. 80 to 150 trunks of documents, notebooks, and technical papers, evaluated in 72 hours. Even if most of the material was personal correspondence and newspaper clippings,

the idea that a thorough technical evaluation could be completed in three days, strains credibility. There's also the question of what was actually in those trunks. Tesla's nephew, Savva Kassanovich, who was also a diplomat for the Yugoslav government, attempted to gain access to his uncle's belongings almost immediately after Tesla's death. he was initially blocked by the government. When he did eventually gain access, he reported that some of Tesla's papers appeared to be missing.

He specifically alleged that a notebook containing technical details about the particle beam weapon was not among the materials returned to the family. Then there's the matter of what the FBI knew. Declassified FBI files released decades after Tesla's death under Freedom of Information Act requests, revealed that the Bureau had been monitoring Tesla for, years before he died. The FBI had a file on Tesla that ran to hundreds of pages. They were tracking his contacts with foreign governments, particularly the Soviet Union. They were aware of his claims

about the particle beam weapon, and they were very, very interested in making sure those plans didn't fall into enemy hands. The declassified files also reveal something else interesting. Despite John Trump's dismissive report, the FBI continued to treat Tesla's papers as a matter of national security for years after his death. The materials were not immediately returned to Tesla's family. They were kept under government control. Some portions were reportedly reviewed by additional military and intelligence analysts beyond Trump's initial evaluation.

The Air Force in particular appears to have taken an interest in the particle beam weapon research, and there are references in the declassified materials to further technical reviews conducted in the late 1940s and early 1950s. There's also the curious case of the missing technical paper. In 1937, Tesla prepared a detailed technical treatise entitled New Art of Projecting Concentrated Non-Dispersive Energy Through Natural Media. This document, which Tesla sometimes referred to as his particle beam paper, contained what he described as the complete theoretical framework for the teleforce weapon.

He reportedly sent copies of this paper to several governments, including the United States, Britain, Canada, and Yugoslavia. He also claimed to have kept a master copy in his hotel room. After Tesla's death, researchers and Tesla enthusiasts spent decades trying to locate this document. The copy that was allegedly sent to the Yugoslav government eventually surfaced at the Nikola Tesla Museum in Belgrade, and it was published in the 1980s. The paper is technically detailed and describes the four main components of the weapon. a mechanism for producing rays in free air,

a method for producing very high electrical force, a means of amplifying that force, and a new method for creating a tremendous electrical repelling force. But some Tesla researchers have argued that the published version is incomplete, that it lacks the specific engineering details that would be necessary to actually build the device, and that the missing pages may still be in government hands somewhere. Whether that's true or simply wishful thinking, I honestly can't tell you.

But the fact that a document Tesla considered his most important technical paper was apparently divided among multiple governments, with no single complete copy publicly available, does nothing to quiet the speculation. Some portions of Tesla's papers were eventually shipped to the Tesla Museum in Belgrade, Yugoslavia, but questions remain about whether everything was included in that shipment. The full accounting of what the government seized and what it did with all of it has never been made completely transparent.

Finally, and this is perhaps the most tantalizing detail of all, there's the question of what Tesla might have kept in his head, rather than on paper. Remember, this was a man who claimed he could design and test complete machines in his mental laboratory without ever writing anything down. If the most critical details of the particle beam weapon existed only in Tesla's mind,

then no amount of document seizure would have captured them. They died with him in that. hotel room unless of course he'd shared those details with someone else before he died and there are people who believe he did now let me be clear about something a lot of what I'm about to discuss falls into the category of historical speculation and conspiracy theory it's important to distinguish between documented facts and unverified claims and I'm going to do my best to keep that distinction clear but the speculation exists for a reason and that reason is the

demonstrable fact that the United States government seized a dead man's papers under legally dubious authority, had them evaluated in what appears to have been an unreasonably short period of time, issued a dismissive report that contradicted the seriousness with which they'd treated the matter, and then kept the materials classified for years. That's not a conspiracy theory. That's a documented sequence of events, and it raises legitimate questions. One of the most persistent theories about Tesla's death ray is that the United States military did, in fact, find something of value in Tesla's papers and used it as the basis for classified weapons research during and after World

War II. Proponents of this theory point to the development of particle beam weapon research programs by both the United States and the Soviet Union during the Cold War. The Soviet program, sometimes referred to in Western intelligence circles by the code name Soyuz, was reportedly quite advanced by the 1970s and 80s. The American program, which was part of the Strategic Defense Initiative, commonly known as Star Wars, under President Ronald Reagan, also invested heavily in particle beam weapon research. Now, were these programs directly based on Tesla's work? There's no declassified evidence that they were, but the timing and the coincidence are striking. Tesla proposed a particle beam weapon in the 1930s. His papers were seized by the government in 1943.

And within a few decades, both superpowers were spending billions of dollars on particle beam weapon research. It's at least worth asking the question. The Strategic Defense Initiative, announced by Reagan in 1983, included a component called the Neutral Particle Beam Program. The concept was remarkably similar to what Tesla had described 50 years earlier. Accelerate subatomic particles to enormous velocities and direct them at incoming ballistic missiles or warheads. The project consumed billions of dollars in research funding before it was scaled back in the early 1990s. Scientists working on the program have never publicly acknowledged any connection to Tesla's work, and it's entirely possible that the technology was developed independently.

But the parallels are hard to ignore. The Soviets, meanwhile, were reportedly even more aggressive in their pursuit of directed energy weapons. Intelligence reports from the Cold War era suggest that the Soviet Union operated multiple research, facilities dedicated to particle beam weapon development. One facility near the city of Semipolitensk in present-day Kazakhstan was reportedly dedicated specifically to charged particle beam research. American intelligence officials spent considerable time and resources trying to determine how advanced the Soviet program was

and whether it posed a genuine threat to American military assets. And here's the thing that keeps the conspiracy theorists up at night. The Soviets paid Tesla 24,000 of the Soviet's paid Tesla 24, $25,000 in 1935 for information about his particle beam weapon. If even a fraction of what Tesla told them was scientifically useful, the Soviet Union had a nearly decade-long head start on particle beam research compared to everyone else. Did that head start translate into an actual weapons program? We may never know for certain.

Another theory, one that's harder to evaluate because it relies primarily on circumstantial evidence and second-hand accounts, is that Tesla's papers, or copies of them, were shared with the Soviet Union. Sava Kosovojanovich, Tesla's nephew, was a diplomat for the Yugoslav government, which was aligned with the Soviet Union during the early years of the Cold War. Some researchers have speculated that Kassanovich may have had access to Tesla's papers before or after the government seizure, and may have shared information with Soviet intelligence. There's no hard evidence for this, but the FBI's declassified files show that the Bureau was worried about exactly this scenario, which suggests they thought it was at least plausible.

There's also the question of whether Tesla himself shared information with the Soviets during his lifetime. We know he received $25,000 from the Amtorg Trading Corporation. We know he was in communication with Soviet officials. What we don't know is exactly what he gave them in return. Tesla claimed he'd provided only a general description of the weapon, not enough to build it. but we have only his word for that. Let me step back from the conspiracy theories for a moment and talk about Tesla's other inventions and contributions

because the death ray, as sensational as it is, sometimes overshadows the full scope of what this man accomplished. Tesla held over 300 patents across 26 countries. He didn't just invent the AC power system. He invented the Tesla coil, which remains one of the most important devices in electrical engineering and is still used today in radio technology, television sets, and various other applications. He developed the fundamental principles of radio communication, and there's a very strong case to be made

that he, not Gugliemmo Marconi, deserves credit for inventing radio. In fact, the United States Supreme Court ruled in 1943 the same year Tesla died, that Tesla's radio patents predated Marconi's, effectively validating Tesla's priority claim. Unfortunately, by then Tesla was dead, and Marconi had already collected the Nobel Prize. Tesla invented the first remote-controlled device, a small boat he demonstrated at Madison Square Garden in 1898. The audience thought it was magic. Some thought there was a tiny person inside the boat. Tesla tried to explain that it was controlled by radio waves, but the concept was so far ahead of its time that most people simply couldn't grasp it. Tesla saw this technology,

as the foundation for what he called automata, which is essentially what we now call robots. He predicted that autonomous machines would one day perform dangerous and repetitive tasks, freeing human beings for more creative work. He was right, but it took the world about a century to catch up with him. Stay tuned for more disturbing history. We'll be back after these messages. This episode is brought to you by Spreaker,

He also made significant contributions to the development of X-ray technology. He conducted some of the earliest X-ray experiments in America, and he produced remarkably clear X-ray images that were among the best of their time. He recognized the potential dangers of radiation exposure, long before most of his contemporaries and took precautions in his work that others didn't bother with. Tesla experimented with what he called very high-frequency electrical currents,

and his work in this area laid the groundwork for what would eventually become radar technology. He published a detailed description of the basic principles of radar in an article in 1917, more than two decades before radar was developed independently by British and American engineers during World War II. When radar was finally deployed in the war, nobody credited Tesla. But his published description of the concept predated the official development by more than 20 years. He also worked on fluorescent lighting, neon lights, and the basic principles of the speedometer. He developed a bladeless turbine that he believed would revolutionize power generation, a device so elegant in its simplicity that engineers are still studying it today.

even if it never achieved the commercial success Tesla predicted. He experimented with cryogenic engineering and was one of the first scientists to observe the phenomenon that would later become known as superconductivity, the ability of certain materials at extremely low temperatures to conduct electricity with zero resistance. He didn't fully understand what he was observing at the time. Nobody would for another several decades, but he documented it carefully and recognized that it was something important. And then there's perhaps the most eerie prediction of all. Tesla theorized about wireless communication in terms that essentially predicted the modern smartphone and the internet. He described in startlingly accurate detail,

a future in which people would carry small devices that would allow them to communicate instantly with anyone in the world, access information from a global network, and even transmit images and video. He wrote about instruments so small that you could carry one in your velds. pocket, instruments through which we'd be able to hear one another and see one another as perfectly as though we were face to face, regardless of the distance between us. He said that a man would be able to conduct his business from anywhere, that he could call up any image from any newspaper or magazine in the world, and projected on a screen, and that the same technology would eventually be used for the transmission of music. Essentially, in 1926, Nikola Tesla wrote about the

iPhone, Netflix, video calling, and digital news media. Now, in the interest of honesty and doing right by you as listeners, I also need to talk about the claims Tesla made that either haven't held up to scrutiny or remain unverified. Because part of understanding Tesla means understanding that his genius and his grandiosity were inseparable. You couldn't have one without the other. The same mind that could envision the modern world with breathtaking accuracy could also convince itself of things that simply weren't true. Tesla claimed at various points that he could transmit electricity through the Earth itself

with no wires and virtually no loss. While he demonstrated some remarkable results in this area, the claim of lossless global power transmission has not been verified, and most modern physicists believe it's not achievable using the methods Tesla described. The Earth is a conductor, yes, but it's a very lossy one, and the energy requirements for the kind of transmission Tesla envisioned would be staggering. He claimed he'd developed a camera that could photograph thoughts. This appears to have been based on a legitimate observation about how the retina processes images,

but the leap from that observation to thought photography was, to put it gently, premature. No evidence exists that he ever built such a device, and the underlying theory doesn't hold up to modern neuroscience. He claimed he'd invented an earthquake machine. As I mentioned earlier, there's a kernel of truth here, as mechanical resonance is a real phenomenon, and Tesla did experiment with oscillators. But the idea that a small device could be tuned to destroy a building, let alone split the Earth, is not supported by the physics, as we understand them. The energy required to produce seismic effects of any consequence is orders of magnitude

beyond what Tesla's oscillators could generate. He claimed he'd detected signals from Mars or another, other planet. He almost certainly detected something real, but it almost certainly wasn't aliens. The most likely explanation, as I mentioned, is that he picked up natural electromagnetic emissions from Jupiter or from atmospheric phenomena he didn't recognize. And he claimed, of course, that he'd invented a particle beam weapon that could destroy 10,000 aircraft at a distance of 250 miles. Whether he actually built such a weapon, or merely developed the theoretical framework for one, or simply believed he had but was mistaken, remains one of the great unanswered questions of

modern scientific history. The honest answer is that we don't know, and the reason we don't know is that the government seized his papers, evaluated them behind closed doors, issued a report that many people find unconvincing, and has never fully declassified all relevant materials. That's the fundamental frustration at the heart of the Tesla story. We don't know what he really accomplished in those final years, because the people who do know, if they're still alive, aren't talking. Let's go back to those final days and the aftermath one more time, because there are a few more details that deserve attention.

After Tesla's death, his body was taken to the Campbell Funeral Parlor at Madison Avenue and 81st Street. A funeral service was held on January 12, 1943, at the Cathedral of St. John the Divine. More than 2,000 people attended, including several Nobel Prize winners and numerous prominent scientists and industrialists. The eulogies praised Tesla as one of the greatest inventors in human history.

Eleanor Roosevelt, the First Lady of the United States, sent a personal letter of condolence. New York Mayor Fiorello LaGuardia read a eulogy written by Tesla's close friend, the author Louis Adamek, in a radio address. It was, by all accounts, a moving and dignified farewell. But it was also tinged with irony because many of the institutions and individuals represented at that funeral had ignored Tesla for decades while he was alive.

The man who'd lit up the world died in a dark hotel room, alone except for the pigeons, and now suddenly everyone wanted to claim a piece of his legacy. Tesla's body was cremated, and his ashes were initially placed in a golden sphere at the Ferncliff's cemetery in Ardsley, New York. They were later transferred to the Nikola Tesla Museum in Belgrade, Serbia, where they remained today. The fate of his papers took considerably longer to resolve. After John Trump's evaluation, the materials remained in government custody. Tesla's family, led by Sava Kosanovich, waged a prolonged, legal, and diplomatic battle

to have the papers returned. The process dragged on for years, complicated by the Cold War politics of dealing with a Yugoslav national who had connections to the communist government in Belgrade. Eventually in the late 1950s and early 1960s, the bulk of Tesla's papers were shipped to Belgrade and placed in the Nikola Tesla Museum. The museum now holds approximately 60,000 documents, thousands of photographs, and a number of Tesla's personal effects and working models.

But the question remains, was everything returned? Were there documents that the government kept? Were there materials that were copied before being shipped overseas? The answers to these questions have never been definitively established, and the United States government has not fully addressed the discrepancies that researchers have identified between what was seized and what was returned. In 2016, the FBI finally declassified its file on Nikola Tesla. The file, which runs to nearly 300 pages, provides a fascinating but incomplete picture

of the government's interest in Tesla and his work. It confirms that the FBI monitored Tesla, that they were concerned about his contacts with foreign governments, that they considered his particle beam weapon claims to be potentially significant, and that they moved quickly to secure his papers after his death. But many of the most interesting details are redacted, and the file raises at least as many questions as it answers. Now, I want to talk about something that doesn't get discussed enough in most Tesla narrative,

and that's the human cost of all this. Because behind the myths and the conspiracy theories and the patent disputes, there was a real person, a person who suffered. Nikola Tesla spent the last three decades of his life in essentially genteel poverty. The man who'd given the world alternating current, who'd laid the groundwork for radio, robotics, radar, and remote control who'd held patents worth hundreds of millions of dollars, this man died owing money to the Hotel New Yorker.

The Westinghouse Corporation, to its credit, covered his hotel expenses during his final years, and provided him with a modest stipend. But the amount was a pittance compared to what Tesla's contributions were worth, and everyone involved knew it. Tesla never married. He was close to several women during his lifetime, including the actress Sarah Bernhardt, the socialite Catherine Johnson, and various other figures in New York's intellectual and artistic circles. but he never formed a lasting romantic partnership. He once told a reporter that he'd sacrificed his personal life for his work,

and that while he sometimes regretted it, he believed the trade was necessary. Whether this was a genuine philosophical choice or a rationalization for his social difficulties is something biographers have debated endlessly. He was, by the end, a profoundly lonely man. His closest companions were the pigeons. His closest confidant was his own. remarkable mind. And when that mind finally went dark on a cold January night in a New York hotel room, the world lost not just a great inventor, but a great tragic figure, a man who'd seen

the future more clearly than almost anyone else in history, and who'd been punished for it by a world that wasn't ready for what he had to offer. So what do we make of all this? What's the takeaway? Here's what I think. And this is just my opinion, so take it for what it's worth. I think Nikola Tesla was one of the most important figures in the history of human civilization. I think his contributions to electrical engineering, wireless communication, and the fundamental infrastructure of modern life are almost impossible to overstate. I think he was done dirty by Edison, by Morgan, by the patent system, by the American financial establishment, and by a culture that valued profit over genius.

I also think that Tesla, particularly in his later years, made claims, that exceeded his evidence. I think the death ray may have been a real concept, grounded in real physics, but I think it's unlikely that Tesla ever built a working prototype. I think the government's seizure of his papers was heavy-handed and legally questionable, and I think John Trump's three-day evaluation was almost certainly insufficient. Whether the government found anything useful in those papers and used it in classified weapons research is a question I can't answer definitively, and neither can't answer definitively.

and neither can anyone else outside the classified world. What I can say is this. The story of Nikola Tesla, from the lightning storm of his birth to the lonely hotel room of his death, is a story that deserves to be told. Not because of the death ray, although that's certainly the hook. But because it's a story about what happens when brilliance meets a world

that isn't equipped to appreciate it. It's a story about the gap between what humanity could achieve and what our economic and political systems actually allow us to achieve. And it's a story about the price that individuals pay when they dare to dream bigger than the people holding the checkbooks. Tesla dreamed a free energy for the entire world. He got a hotel room, some pigeons, and a file at the FBI. There's a word for that, and the word is disturbing. Tesla's legacy has experienced a remarkable resurgence in recent decades.

The Tesla Science Center at Wardencliffe was established, through a crowdfunding campaign that raised over $1 million, and the site of Tesla's last great laboratory is now a museum and educational center. Elon Musk named his electric car company after Tesla, though the connection is more inspirational than technical. Tesla's image has appeared on currency, on postage stamps, and in countless films, television shows, books, and video games. He's become, somewhat ironically, a pop culture icon. the kind of figure who shows up on t-shirts and coffee mugs, which is a strange fate for a man who could barely afford coffee during the last years of his life. But perhaps the most important part of Tesla's legacy is the questions he left behind.

What if Wardencliffe had been completed? What if wireless power transmission had been developed a century ago? What if the death ray was real? And what if someone, somewhere, has the plans? These are questions we can't answer. but they're questions worth asking. Because the story of Nikola Tesla isn't really over. As long as the full contents of his seized papers remain uncertain,

as long as governments continue to research particle beam weapons, and as long as there are people willing to look at the official story and say, I'm not sure I believe that. The story continues. And that's what makes it a disturbing history. Thanks for listening. And remember, the next time you flip a light switch, plug in your phone or turn on the radio,

You're using technology that exists because a skinny kid from a small village in what's now Croatia looked up at a lightning storm and decided he could do better. He could. He did.
