Ten thousand supersonic jets soar through international airspace, poised to start World War Three. Each plane carries 100 eager paratroopers with a combined invading force of 1 million soldiers. The squadron crosses the ocean, still 250 miles from their target. White light flashes near the lead jets noses so bright it blinds the soldiers inside. It strikes the entire squadron too fast for even the furthest planes to nosedive away. The vibrant beam shines through each plane's metal hull, penetrating layers of titanium at the atomic level. Radiation melts a glowing red circle of sky where chairs and bodies used to be all at once. The GPS and comms scramble. The alarm blares and yellow oxygen masks spring from the ceilings. Air sucks out of each plane's cabin, replaced with acrid toxic smoke. But the remaining soldiers are in such excruciating pain, they don't notice that they can't breathe. The lethal blast of radiation burns their skin. Midnight black waves of nausea roll through them as their deep DNA unspools. They don't even have time to scream before it's over. The waves of irradiated heat hit the fuel chambers and 10,000 planes explode into flaming orange smoke. Near instant annihilation of a million people. For the squadron's target city, it's a crisis averted. Their top tier defense system worked, destroying threats on the subatomic level. They call it the death ray. It's the most powerful weapon in the world, or would be if it existed. Officially, Nikola Tesla's death ray never made it out of his notebooks. But some people think the US government stole those notebooks to protect this advanced technology or keep it all to themselves. Welcome to Conspiracy Theories, a Spotify podcast. I'm Carter Roy.

The conspiracy theories about Nikola Tesla's missing possessions started the day after he died on January 8, 1943. Tesla's next of kin, his nephew Saba Kosanovich, followed a housekeeper upstairs inside the New Yorker Hotel. She led him to room 3327, where Tesla had called home for the past few years. For Kosanovich, it felt surreal to enter the room. On one hand, it was the home of a genius inventor. On the other, it was a mouse. Books, papers and boxes were strewn about the suite. Desks were piled with stacks of documents. Kosanovich was there to organize Tesla's work, and the job was clearly a big one. Kosanovich sifted through diagrams of electric gizmos, remote control devices and radio towers. Then he noticed something odd. Some of Tesla's papers had been tampered with, at least One of his notebooks was missing. Plus, Tesla's Edison medal, the most prestigious scientific award he ever received, was nowhere to be found. A chill ran down Kosanovich's spine. Someone had already been here. He couldn't be positive about what else might be missing. It wasn't like his uncle kept an inventory, and they weren't particularly close. But Kosanovich was convinced someone had entered the room before him and stolen Nikola Tesla's belongings. He had a sneaking suspicion that it had been a representative from the US Government. They'd never liked his uncle, never accepted him as a citizen. But now that Tesla was gone, they wanted to use his genius for their own gain. Okay, now, if you're thinking. Hold on, Carter, who are you talking about? The only Tesla I know is my neighbor's electric car. Don't stress. The car company is named after the inventor Nikola Tesla. He was born in 1856 in Smiljan, Croatia. Family lore says he entered the world during a lightning storm as an adult. He became an inventor, focusing on ways to use and harness this newfangled discovery called electricity. This eventually led him to immigrate to the US for better opportunities. And while Tesla sometimes worked directly for companies as an employee, he spent most of his life selling patents for inventions big companies could take wide, or seeking investors so he could build proofs of concept. Kind of like the contestants on Shark Tank. Some of Tesla's patents included different types of motors, light bulbs, even X rays. Ah, yes. For every broken bone you've seen, you can thank Nikola Tesla. Well, not for breaking your bones, for being able to see them. But he's most famous for pioneering the use of alternating current electricity. If you have ever plugged anything in at your house, you've used alternating current. Historically, almost the entire US Power grid has run on it. And this is the thing about Tesla. Regardless of everything else that you think of him or that we're about to learn about him, he essentially invented the power grid that we all live on. It is unbelievable, the scope of his impact. And Tesla figured that out when he was only 26. Well, if you're over 26, don't feel too bad, though. Don't think about changing your life to be like him. Because Tesla famously had almost no social life. He didn't date. He skipped lunch. He slept maybe five hours a night. The other 19 hours, he spent working. And this led to a mental health condition which flared up on and off through the course of his life. In the 1890s, Tesla's work attracted the attention of consultants from the Niagara Power Company. They were creating a new water powered electrical generator that drew power from Niagara Falls. Tesla was exactly the man they needed to complete their work. So they offered him a job. Tesla accepted without hesitation. He created a motor that would convert the energy from moving water into electricity. And his invention worked better than anybody could have imagined. After three years of construction, the Niagara Falls Power Plant opened in the mid-1890s. It lit up the entire city of Buffalo, New York, all using alternating current. It made Tesla famous. But not all the attention was good. According to Saba Kosanovich, the US Government actively monitored Tesla. And Kosanovich wasn't the only one who thought so. One rumor claimed that government agents had been renting a room at the New Yorker Hotel, right across the hall from the room Tesla lived in during his final years. Allegedly, these tenants were members of the FBI sent to monitor Tesla's movements. If agents really were living next door, they would have been intimately aware of the inventor's schedule. They could have realized that Tesla had passed away and broken into his room and stolen his belongings before anyone else even knew he was dead. At the time Kosanovich made this claim, people said it was outlandish over inflating Tesla's importance. But the rumor still persisted for decades. Then, in 2017, it turned out to be true. The US government really was monitoring Tesla. Between 2016 and 2018, the CIA released a dossier containing over 200 pages of documents relating to Nikola Tesla. They included notes about the inventor's creations, discoveries and idiosyncrasies. One declassified report revealed that one of Tesla's own colleagues was a government informant. His name was Blois Fitzgerald. Yeah, you heard that right. Blois. He was an electrician and one of Tesla's most trusted proteges. But he betrayed his mentor. For years, he reported nearly all of his and Tesla's private conversations to the FBI. Fitzgerald also told the FBI that Tesla carried 80 trunks of notes with him every time he moved to a new hotel. He clearly knew what kinds of inventions those papers held and how valuable they might be. It's possible Fitzgerald himself snuck into Tesla's room after he died. After all, he already demonstrated he was willing to betray his friend. Perhaps the director of the FBI, J. Edgar Hoover, ordered Fitzgerald to take specific documents from Tesla's room. Because some of Tesla's inventions and ideas were intentionally kept secret by Tesla himself, he chose not to share them or even to try to sell them. For example, he invented an alternating current motor that would work with just two wires but chose not to try to sell it. What? Why? Well, apparently it was based on the electrical systems of the time. And Tesla didn't want to encourage people to stick to old systems. He wanted to create a new, better electrical system. And this exemplifies something really important about Tesla. He hoped that one day his inventions would lead to universal peace and prosperity. He believed that someday all labor would be automated and no one would want for anything. If this sentiment feels familiar, it's because it is still part of the conversation around cutting edge technology today, like AI. So to protect his work and hopes for the future, Tesla kept his secrets locked up in his 80 trunks. We only know about the two wire motor concept because he eventually shared it with a friend. So it makes sense why the government was monitoring Tesla. He'd proven his inventions had the power to change the world. He was secretive. And his inventions weren't always developed in the interest of public safety. He spent years trying to transmit wireless electricity through the ground at his lab in Colorado Springs, even though his experiments shocked nearby horses and electrocuted local butterflies. But those aren't the only reasons the US Government saw Tesla as a possible concern. Leading up to World War II, the FBI kept extensive files on everyone Director J. Edgar Hoover considered to be a national security threat. And Hoover had a whole folder dedicated to Nikola Tesla. Because Sava Kosanovic wasn't just Tesla's random nephew. He was a foreign diplomat, the ambassador of Yugoslavia. And leading up to Tesla's death, Yugoslavia was controlled by the Axis powers, America's enemies. During World War II, the FBI suspected Tesla, an Eastern European immigrant himself, might have ties to the enemy. And the US Government couldn't let important inventions fall into enemy hands. So to keep Americans safe, they secretly broke the law. And they may have stolen the most dangerous weapon ever created.

Leading up to his death in 1943, the US government actively monitored Nikola Tesla. According to his nephew, government agents might have even broken into Tesla's hotel room the day he died. And when you hear what happened two days later, it feels increasingly possible because they did illegally break into his room two days after Tesla died, after Kosanovich had already visited and grown suspicious, on January 9, 1943, the US government walked out of Tesla's hotel room with 80 trunks worth of documents. Nikola Tesla absolutely had information the US Government wanted kept quiet. The question is what that information was and what they did with it. You see, when the US Government confiscated Tesla's belongings, they didn't send the FBI. They sent an agency called the Office of Alien Pro Property Custodian, or the oapc. The OAPC was a wartime agency. Their job was to confiscate potentially valuable assets from America's foreign enemies. But Tesla was a naturalized US citizen. He'd been one for over 50 years, more than half his life. Naturally, Kosanovich argued that the OAPC had no legal rights to his uncle's work. And he was right, they didn't. They only had the power to confiscate items from non citizens. So Kosanovich appealed the seizure, fighting to regain his inheritance. But the agents weren't exactly keen to listen to him. Remember, Kosanovic was a Yugoslavian ambassador. He'd actually used his famous uncle's name to rise through the ranks of international politics. Government agents suspected Kosanovich had ties to Yugoslavia's Communist Party. And as the world moved From World War II to the Cold War, it was imperative to keep technological advances on the American side of the Iron Curtain. So they rejected his requests, keeping the fight in the courts. Meanwhile, the OAPC gave Tesla's papers to a military engineer named Dr. John Trump. Yes, they're related. Within just a few days, Dr. Trump officially concluded that there was nothing dangerous in Tesla's notes. He said Tesla's thoughts and efforts during at least the past 15 years were primarily of a speculative, philosophical and somewhat promotional character, often concerned with the production and wireless transmission of power, but did not include new, sound, workable principles or methods for realizing such results. Since then, the US Government has tried to downplay the significance of the documents. Even so, they engaged in nine years of legal battles with Kosanovich. It wasn't until 1952 that federal judges ruled that Tesla's Papers had been wrongly seized and should be returned to Casanovich. Should have been an immense relief. But when Casanovich counted them, there were only 60 trunks. Kosanovich knew his uncle had kept 80 trunks, which left him wondering where those missing trunks had gone. At the time, the United States claimed that they'd simply consolidated Tesla's work for easier shipping. But 20 whole trunks don't just disappear. By rearranging a few notebooks, this implied the officials were hiding pages from Tesla's family and from the rest of the world. And they weren't the only government acting shady. Kosanovic donated his 60 trunks to a museum in Belgrade in modern day Serbia. From then on, if anyone in the west requested access to the papers, and they were almost always denied. A few scholars got access to select papers over the years, but in general, the Yugoslavians kept Tesla's work to themselves. Seems like they also believe there was something in there worth hiding. And here's where it gets even wilder. According to Kosanovich, it involved blueprints for a super weapon Tesla tried to sell to both countries. It started back in the 1930s, about a decade before Tesla died. He publicly stated he was working on the most powerful weapon ever created. This was not one of the secretive ideas he tinkered with alone. He wanted this invention to come to life. It was a particle beam weapon that he called a teleforce gun. According to him, the device could down an airplane from 250 miles away and was so deadly it would put an end to warfare. It was called the Peace Ray because it would prevent any nation from attacking another. In 1934, Tesla told the New York Times the death beam would make war impossible by offering every country an invisible Great Wall of China. Bear in mind this is happening as the Nazis are invading Eastern Europe and shortly before the US Greenlights the Manhattan Project to invent the nuclear bomb. Tesla was ahead of his time thinking about mutually assured destruction before anyone had the capability to enact it. But unlike the nuclear bomb, Tesla wanted everyone to have one. He hoped to install the Peace Ray in every country and create an even playing field. Now, the concept of a massive protective ray gun wasn't completely original. Other American and European inventors in the early 20th century experimented with the idea. Most of these were planned as essentially giant superlasers. And they all kept running into the same problem. Lasers get weaker the further they travel. But Tesla thought he had a solve for this. He wanted to blast tiny electronically charged particles instead of just light. So something between a taser and A BB gun on a massive scale. Even though Tesla called it the teleforce gun, when he started shopping it around, the press saw the similarities to the light ray weapons other inventors were working on. So they labeled it Tesla's death ray. Which stuck. We can't always choose our names. When World War II broke out in 1939, public interest in Tesla's teleforce gun increased. Apparently, Tesla tried to sell the patent to the US and UK governments. One released memo alludes to a batch of death ray notes that the US government acquired in 1934. It doesn't say if they were confiscated or if Tesla shared them in hopes of a sale. Either way, neither the US or UK bought the death rate patent, possibly because Tesla was in his 80s and hadn't produced a successful invention in years. So Tesla went looking for another buyer. A letter he wrote to Kosanovich in the early 1940s said he'd partnered with Amtorg Trading Corporation, a company based in the Soviet Union. Together they'd sell Tesla's latest invention to Yugoslavia. Records suggests that Amtorg Trading Corporation intended to pay Tesla $25,000 for a patent. But there's no proof this deal went through. Amtorg Trading Corporation didn't mention Nikola Tesla anywhere in their own paperwork. They and there's no indication that Tesla received any large sums of money around the time this sale supposedly took place. And of course, well, Yugoslavia never built a death ray. Or if they did, they didn't use it before the nation broke up into the modern day countries of Slovenia, Croatia, Bosnia and Herzegovina, Montenegro, Serbia and Macedonia. There's been enough instability in the region that if anyone had a death ray, they had ample motive to use it. Even though Tesla couldn't find a buyer for the death ray, the FBI decided to keep tabs on it. According to declassified notes, they became intrigued by the death ray as early as 1940, three years before Tesla died. One memo addressed to FBI Director J. Edgar Hoover requests that steps be taken to make sure Tesla was not abducted by enemy governments in case they'd make their hostage build the deadly weapon. You know, kind of like the plot of the first Iron man movie. This might be part of why the FBI was watching Tesla. Not to harm him, but to protect him. Or I mean really to protect the death ray design from getting into the wrong hands. To be clear, in 2008 the FBI came out and said they never had possession of any of Tesla's papers for prototypes. The Bureau claimed they were misidentified with agents of the Office of Alien Property Custody, who were deeply interested in a possible death ray. Regardless, while Sava Kosanovich was trying to get his uncle's papers back, the US Military made use of them. You see, some of the documents that Dr. John Trump reviewed for the OAPC featured notes and sketches that detailed how the death ray would work. The blueprints reportedly showed a large tube mounted at the top of a signal tower. This tube focused a beam of electrically charged particles, which could be fired over huge distances. According to Tesla, this beam could destroy an airplane from hundreds of miles away. In 1943, the United States supposedly distributed these death ray blueprints to the FBI and the Department of Defense. They seem to think their scientists could take Tesla's designs and improve them for mass military production. Allegedly, the project was deemed infeasible and canned. But 15 years later, in 1958, DARPA, the Defense Advanced Research Projects Agency, greenlit Project See saw with the goal of creating a particle beam weapon. Officially, after 10 years and $27 million, that project was canned, too. Then, in the 1980s, 50 years after Tesla's death, President Ronald Reagan announced the Strategic Defense Initiative, better known as Star wars, because the plan felt like something out of a sci fi movie. It poured billions of dollars into developing America's nuclear missile defense system. And among the many methods they explored, a particle beam gun to shoot down incoming threats. Tesla biographer Mark Cipher believes it's possible that Tesla's death ray lent some of its ideas to Reagan's Star wars program. And if so, that's why they can keep some of Tesla's papers classified. Today, a Freedom of Information act request wouldn't trigger the release of anything still classic classified. Basically, Sava Kosanovich never got those 20 trunks of documents back because the US military is still using them. There's a possibility the US military has a death ray right now, or has one in the works. At the very least, there's plenty of evidence they want one. Which gives even more credence to Kosanovich's claim that government agents secretly robbed Tesla's hotel room the very day he died. They could say anything taken in this initial secret raid was actually taken during the official one two days later. Wouldn't be the first case of search first warrant later. And they might have taken more than the blueprints for the death ray. Nikola Tesla was prolific. For 80 years, he constantly brainstormed new inventions. Tesla's notes included ideas to remake the power grid all over again and fill the streets with electric cars. Officially, those ideas never left his notebooks. But is that because they weren't possible in the 1940s or because someone stole the technology and intentionally suppressed it from the public? And was that someone the US Government or a business rival?

Much about Nikola Tesla before, you might be aware of his rivalry with Thomas Edison. Edison's best known for inventing the modern light bulb, though Tesla also invented a light bulb with a different mechanism. Longtime listeners might also recall our episode on the theory that Edison had one of his competitors murdered. Louis Le Prince, who invented the motion picture camera, which is to say, Edison had a reputation for playing dirty. Tesla and Edison first met when Tesla worked for Edison's company. But Tesla quickly moved on to work for himself and then started selling patents to Edison's main competitor, Westinghouse. Westinghouse helped bring Tesla's concept of alternating current electricity to life, which directly competed with Edison's bread and butter direct current electricity. Okay, a little science fair here. At the time, America was using Edison's system, making him rich. But Tesla and Westinghouse's system was both cheaper and better. So Edison launched a massive PR war to save his company. He even went as far as convincing the state of New York to use a Westinghouse alternating current generator for a death row execution. And when the execution was botched, they blamed Tesla's invention. But in the end, alternating current was simply a better system, so it won out. Now, Edison died years before Tesla, but perhaps someone from Edison Electric broke into Tesla's hotel room to prevent another Tesla invention from jeopardizing their business. And maybe they stole Tesla's Edison award, too, the one Kosanovich noted was missing. What exactly Would they have been looking for ideas that would disrupt their business model? For example, Tesla tinkered with a concept he called free energy that powered an ambient air device that took heat from its surroundings and converted that into electricity, exactly like a solar panel. Now, Tesla never built a working solar panel, but he had notes about it. And as we've seen, solar panels have begun to disrupt the electricity industry. Instead of paying for electricity, some people are able to harvest their own or even sell it to their local power company. We know Edison and his team did everything in their power to suppress alternating current because it went against their business interests. They were and are currently an electricity company. So might they have suppressed better technology again with solar panels? And that's not the only alternative means of electricity Tesla was investigating. He spent his final months tinkering with a lifelong obsession, wireless electricity. Years before, he'd invented the Tesla coil, which transfers power through the air to it simply, two Tesla coils form an electrical circuit and generate a magnetic field. At his lab, Tesla used these coils on a small scale to power lights and remote controlled automatons. But he hoped to bring wireless power to the whole world via massive towers, like cell phone towers. Now, Tesla's wireless electricity dream wasn't possible in his time. But in January 2021, students at Georgia Tech proved that the millimeter waves in 5G phone signals could be harnessed and converted into small amounts of electric power. And as of 2025, a company called ReachPower is building out long distance wireless power transmission systems. Their website lists both NASA and DARPA as partners. So it is possible. Possible enough that someone might have wanted to prevent it from ever happening or wait until it was built by someone who'd license it to the government. Then there's the invention most famously associated with the name Tesla. The electric car. Yes, we have finally arrived at the place we all at least know the name from. Tesla and the electric. How do they go together? Well, according to one theory, before he died, Nikola Tesla worked on an electric car concept. We could do a whole episode on the conspiracy theories to stop the progress of electric cars. But the general concept goes all the way back to at least the 1800s. At one point, Edison Inc. And Ford Motors teamed up to create an affordable electric car. They tested dozens of designs, but the project eventually fell apart. According to Tesla's other nephew, Peter Tsavo, in September 1931, Tesla brought him to Buffalo, New York. Yes, that's the city Tesla single handedly brought electricity to. And in Buffalo, Tesla showed his nephew what seemed to be a normal car. But when he popped the hood, Szavo saw something completely unexpected. Tesla had removed the car's engine and replaced it with a battery. Salvo was fascinated. He asked Tesla how it worked, but the inventor was tight lipped. All he said was that they should take the machine for a test drive. Salvo climbed into the driver's seat and turned the key in the ignition. The car started, but unlike a gas powered vehicle, it. It didn't make any noise. Salvo noticed that it had an antenna, and his uncle explained that the power was coming from a nearby Tesla coil, a wireless electrical tower. With that explanation, the men set off. During their test drive, the new electric car accelerated to 90 mph. The drive was fast, smooth, and completely battery powered. If this story is true, it means the technology for electric cars existed almost a hundred years before their widespread adoption. But someone suppressed it before they could go mainstream. Just like Thomas Edison and his company tried to suppress alternating current. Okay, let's take a look at this, because there are a few lingering questions. First, if Edison Incorporated had a secret stolen blueprint, why not build a car and pass it off as their own? If the government had it, why not use it for the military? Some say the oil and gas lobbies would have killed it. But they weren't as powerful in the 1930s as in the 1990s and 2000s. They hadn't made their billions yet. Lastly, the records don't entirely line up. Given poor record keeping in the early 20th century, we can't even say for sure that Salvo was really Tesla's nephew, much less that they knew each other. And at the time the story allegedly occurs, Tesla was struggling financially. He didn't have the resources to build an electric car. And if he did, he likely would have sold it. In all likelihood, Tesla never worked on a battery powered automobile. And it's just a popular story, a fun urban myth. Still, in the decades after Tesla's death, technology developed quickly. Maybe too quickly. Some suspected that the government was innovating off Tesla's stolen notes. They think the FBI stole these blueprints, then engineered the technologies for mass consumption. And they never gave Tesla the proper credit. Meaning it's possible that the government didn't just steal Tesla's notes. They might have seized his entire legacy. It's similar to theories about reverse engineering. The idea that the US Military used recovered alien technology to make major leaps in aeronautics and weapons. But in this case, they used it to make leaps in electronics and communications. Speaking of aliens, there's one specific Tesla Invention the US Military would want to have and have reason to keep quiet. An alien communicator. Oh, yeah, I might have forgotten to mention that. Nikola Tesla claimed he'd invented a way to receive signals from extraterrestrials and got a message from Mars. Okay, yeah, here we go. This goes back to the late 1890s, when Tesla registered the first US patents for radio technology. But they weren't the first radio patents in the world. In Europe, an Italian inventor named Guglielmo Marconi registered paperwork for nearly identical technology. Suddenly, Tesla had serious competition. If he wanted to stay ahead, he needed a technological breakthrough fast. And that required more money. So Tesla convinced banker J.P. morgan to fund him with the explicit promise that he'd outpace Marconi. Intrigued, Morgan invested $150,000, the equivalent of over $4.5 million today. Tesla set up two research stations dedicated to radio experimentation. The first was established in 1899 in Colorado Springs, where high altitude helped optimize signal transmission. The second was built in 1901 on Long island and was called Wardenclyffe Tower. One day, while searching for signals, one of Tesla's receivers pulsed in an odd rhythmic fashion. The series of electrical disturbances felt timed, intentional. He described them as 1, 2, 3. They were like no signal his transmitters had picked up before. Upon further study and reflection, he deduced they had to be coming from outer space, specifically Mars. He wanted to find a way to signal back. He hoped to hear the 1, 2, 3 again and answer 4. Tesla felt this discovery was of global importance, so he shared it with the world. And it didn't go over well. Some members of the public believed him, but the scientific community scoffed. His professional and public reputation took a massive hit, and there was no way Tesla could have detected signals from Mars. And now, almost a century later, we can be fairly certain Mars isn't sending out electrical signals. That said, just a few years after Tesla died, the US Air Force launched Project Blue Book, which was dedicated to studying possible extraterrestrial encounters. Even though Tesla's claim went nowhere, they might have wanted to examine it for themselves. One final invention the US Government may have wanted to get their hands on a machine to control the weather. Tesla openly stated his belief that a strong enough radio transmission tower might be able to influence the weather. He hoped to eventually create one in Colorado Springs. As far as we know, he didn't achieve that, though the weather's great in Colorado Springs. But his notes may have paved the way for projects like. Like haarp. Officially, it's a radio transmitter in Alaska that studies our upper atmosphere. But some people think HAARP is actually a weather control device. We've covered it before, if you want more info. But it's just one of the many modern things Tesla's missing notes might have inspired. Okay, let's sum it up. Nikola Tesla's notes might have included plans for death rays, weather machines, alien transmissions, electric cars, and wireless electricity. And those are just the experiments we know of. The 20 missing trunks could also contain technology Tesla kept secret from the public. Or maybe they held nothing at all. Because as much as Tesla was a visionary, he may also have been a scam artist. Remember, Tesla registered over 300 patents, many for inventions that were never built. So he can't guarantee everything he invented worked. And he was known to inflate the importance of his work. While Reviewing Tesla's belongings, Dr. John Trump learned that the inventor had left behind more than just notes. Employees at the New Yorker Hotel told Trump about a safe at the nearby hotel Governor Clinton, where Tesla used to live. He'd left a prototype there as collateral. Okay, so by his 70s, Tesla was eyeballs deep in debt. He had to sell off his radio tower, financed by JP Morgan. He moved from hotel to hotel, taking his 80 trunks every time. He racked up massive bills and didn't always pay them. When he left the Governor Clinton Hotel, he had $400 in charges. Instead of paying, he allegedly gave them a prototype of the death ray. When John Trump learned this from the employees at the New Yorker Hotel, he was stunned. He dashed to the Governor Clinton Hotel and persuaded those hotel employees to show him the box. They pulled it out of their safe, and the collateral was wrapped in a paper bag with a handwritten note from Tesla. It said the device was worth $10,000 and that the hotel should keep it as collateral. While Tesla worked to pay his outstanding bill, he told the staff the box contained a secret weapon. If any unauthorized person tried to open the box, the device would explode. Dr. Trump didn't know if that was true. But there was only one way to find out. He gathered his courage and carefully opened the package. Then he burst out laughing. It wasn't a weapon of war. It was a multi decade resistance box. A common piece of equipment found in any electrician's laboratory. Nikola Tesla had conned the Governor Clinton Hotel to get out of paying his bill. After discovering this scam, Dr. Trump closed his investigation into Tesla's death ray. It seemed like the prototype had never existed outside Tesla's mind. He'd used his reputation as a famous inventor to make people believe he was more capable than he was. And if Tesla talked up the death rate to avoid paying his debts, what other inventions might have been a scam? Some people say he made up the story about the Mars transmission after Guillermo Marconi beat him to the punch on radio. And he never truly cracked wireless electricity, despite using it to rake in thousands from JP Morgan. And even though modern electric cars bear his name, most historians agree that the tale of Tesla Building 1 is an urban legend. And this is what I love so much about the mythos of Tesla. It lives in the gray. Was he maybe the greatest inventor of the 20th century, the godfather of our best technology? Or was he another hustler, a smart guy creating great stuff and trying to make his way through his world? Probably the truth is a bit of both. So while it's possible the US Government is hiding a death ray or incredible technological advances from the public, it's also possible Tesla was the one lying to us all along.

This episode explores one of history's most tantalizing what-ifs: the mysterious disappearance of Nikola Tesla’s inventions following his death in 1943—particularly the so-called "Death Ray" or "teleforce" weapon. Carter Roy investigates the conspiracy theory that the U.S. government stole and possibly weaponized such advanced technology, delving into Tesla's life, his secretive nature, infamous rivalries, and the enduring legacy of his missing trunks and papers. Blending historical fact with speculation, the episode asks whether Tesla was a misunderstood genius whose work was suppressed, a brilliant hustler inflating his legacy, or a bit of both.
Opening Scenario (00:01–01:45): Carter Roy sets the scene with a dramatic (fictional) account of a "death ray" obliterating an invading fleet—illustrating public fascination with Tesla’s rumored weapon.
The Myth’s Origins (05:35–09:50):
"For years, [Fitzgerald] reported nearly all of his and Tesla's private conversations to the FBI."
—Carter Roy [08:45]
Tesla’s Defensive Motives: Tesla intentionally kept secrets, fearing misuse of his work but also hoping for universal prosperity—putting him at odds with both governments and business interests.
"20 whole trunks don't just disappear by rearranging a few notebooks. This implied the officials were hiding pages from Tesla's family and from the rest of the world."
—Carter Roy [18:44]
"Tesla was ahead of his time thinking about mutually assured destruction before anyone had the capability to enact it."
—Carter Roy [23:41]
Business Motives (31:24–37:00):
"They were and are currently an electricity company. So might they have suppressed better technology again with solar panels?"
—Carter Roy [34:19]
Wireless Electricity and the Electric Car:
"If this story is true, it means the technology for electric cars existed almost a hundred years before their widespread adoption. But someone suppressed it before they could go mainstream."
—Carter Roy [36:15]
Extraterrestrial Communication (39:15–42:45):
"Upon further study and reflection, he deduced they had to be coming from outer space, specifically Mars."
—Carter Roy [40:18]
Weather Manipulation:
"It wasn't a weapon of war. It was a multi decade resistance box. A common piece of equipment found in any electrician's laboratory. Nikola Tesla had conned the Governor Clinton Hotel to get out of paying his bill."
—Carter Roy [47:01]
On Government Motives:
"To be clear, in 2008 the FBI came out and said they never had possession of any of Tesla's papers for prototypes. The Bureau claimed they were misidentified... Regardless, while Sava Kosanovich was trying to get his uncle's papers back, the US Military made use of them."
—Carter Roy [27:50]
On the Mystery’s Core:
"So while it's possible the US Government is hiding a death ray or incredible technological advances from the public, it's also possible Tesla was the one lying to us all along."
—Carter Roy [49:20]
On the Enduring Enigma of Tesla:
"It lives in the gray. Was he maybe the greatest inventor of the 20th century, the godfather of our best technology? Or was he another hustler... Probably the truth is a bit of both."
—Carter Roy [49:07]

"Tesla's Death Ray" expertly weaves fact, myth, and speculation, using Tesla’s real achievements and eccentric personality as a springboard for larger questions about invention, suppression, and the particularly American appetite for secret technologies and shadowy government plots. The episode invites listeners to weigh evidence of government intrigue and potential technological theft against the very real possibility that Tesla’s most outlandish claims were just that—claims, never realized. Ultimately, Carter Roy leaves us in the gray area that makes Tesla's legacy irresistible: perhaps both a pioneer and a self-promoter, with the secrets to a "death ray" still locked away—or never existing at all.
