WEBVTT 00:00:00.000 --> 00:00:02.359 Welcome to the Deep Dive, where we plunge into 00:00:02.359 --> 00:00:04.679 a stack of source material, articles, research 00:00:04.679 --> 00:00:07.379 papers, original notes, and surface with the 00:00:07.379 --> 00:00:10.060 condensed, high -impact knowledge you need. We're 00:00:10.060 --> 00:00:11.900 here to give you the shortcut to being truly 00:00:11.900 --> 00:00:14.779 well -informed. And today, we are embarking on 00:00:14.779 --> 00:00:17.219 a dive into the life of one of history's most 00:00:17.219 --> 00:00:20.719 recognizable yet persistently misunderstood figures, 00:00:21.000 --> 00:00:23.800 Nikola Tesla. He was the Serbian -American engineer, 00:00:24.079 --> 00:00:27.620 futurist, and inventor whose vision, I mean, 00:00:27.620 --> 00:00:30.539 it fundamentally sculpted the modern world. It's 00:00:30.539 --> 00:00:33.640 hard to overstate his foundational impact. His 00:00:33.640 --> 00:00:36.700 work gave us the alternating current or AC electricity 00:00:36.700 --> 00:00:39.060 supply system. Which is the infrastructure that 00:00:39.060 --> 00:00:40.899 powers virtually everything in your life right 00:00:40.899 --> 00:00:43.420 now. Exactly. And it's a recognition of his raw 00:00:43.420 --> 00:00:46.219 scientific contribution that the SI unit of magnetic 00:00:46.219 --> 00:00:49.380 flux density is officially named the Tesla. That's 00:00:49.380 --> 00:00:51.700 the rare air of genius. Our mission today is 00:00:51.700 --> 00:01:02.740 to look past the mythology. Right. Right. We'll 00:01:02.740 --> 00:01:05.780 trace his trajectory from his challenging European 00:01:05.780 --> 00:01:08.439 education and his early catastrophic financial 00:01:08.439 --> 00:01:11.400 failures through the brutal commercial reality 00:01:11.400 --> 00:01:14.000 of the war of the currents. And then into his 00:01:14.000 --> 00:01:17.519 ambitious, sometimes hubristic, wireless power 00:01:17.519 --> 00:01:21.120 projects and his complex, eccentric final years. 00:01:21.400 --> 00:01:24.560 We aim to distill his sheer technical brilliance, 00:01:24.599 --> 00:01:27.760 certainly, but also understand the personal traumas, 00:01:27.760 --> 00:01:31.079 the commercial betrayals, and the profound, sometimes 00:01:31.079 --> 00:01:34.010 bizarre, philosophical beliefs that set him apart. 00:01:34.269 --> 00:01:37.090 You'll find that the real story is far more dramatic 00:01:37.090 --> 00:01:38.969 and contradictory than the legend. It really 00:01:38.969 --> 00:01:40.870 is. Okay, let's unpack this, beginning at the 00:01:40.870 --> 00:01:43.549 genesis of his genius. Nikola Tesla was born 00:01:43.549 --> 00:01:46.209 on the stroke of midnight, according to his autobiography, 00:01:46.329 --> 00:01:50.310 on July 10, 1856, in the small village of Smiljan. 00:01:50.569 --> 00:01:52.750 Which was then part of the Austrian Empire, now 00:01:52.750 --> 00:01:55.269 modern -day Croatia. Correct. He belonged to 00:01:55.269 --> 00:01:57.810 an ethnic Serb family. His father, Malut and 00:01:57.810 --> 00:02:00.450 Tesla, was a respected Eastern Orthodox priest. 00:02:00.730 --> 00:02:03.049 And the expectation, naturally, was that Niccolo 00:02:03.049 --> 00:02:04.730 would follow his father into the priesthood. 00:02:04.849 --> 00:02:08.090 Of course. But the genius was cultivated by a 00:02:08.090 --> 00:02:10.969 different source. Tesla consistently credited 00:02:10.969 --> 00:02:15.050 his mother, Georgina or Ukamandich, as the dominant 00:02:15.050 --> 00:02:17.289 mechanical and creative influence in his life. 00:02:17.530 --> 00:02:20.490 She had no formal education, right? None. But 00:02:20.490 --> 00:02:23.069 she was profoundly talented. She invented and 00:02:23.069 --> 00:02:25.250 constructed various home tools and mechanical 00:02:25.250 --> 00:02:28.569 devices, looms, household aids, agricultural 00:02:28.569 --> 00:02:31.810 tools. And Tesla attributed not only his creative 00:02:31.810 --> 00:02:34.669 impulse, but specifically his eidetic memory. 00:02:35.080 --> 00:02:37.819 The ability to recall images and objects in perfect 00:02:37.819 --> 00:02:40.219 detail, as if they were physically present to 00:02:40.219 --> 00:02:42.900 her. That eidetic memory allowed him to essentially 00:02:42.900 --> 00:02:45.340 conduct experiments and build complicated machinery 00:02:45.340 --> 00:02:48.080 entirely in his head. Without ever needing sketches 00:02:48.080 --> 00:02:50.560 or physical models, it's an almost unimaginable 00:02:50.560 --> 00:02:52.599 advantage. And this ability had shown through 00:02:52.599 --> 00:02:55.319 early. In high school in Karlovac, he finished 00:02:55.319 --> 00:02:57.259 the four -year curriculum in just three years. 00:02:57.419 --> 00:03:00.120 Right, graduated in 1873. And he became deeply 00:03:00.120 --> 00:03:02.080 fascinated by electricity, which he described 00:03:02.080 --> 00:03:05.050 as the mysterious phenomena. But this early success 00:03:05.050 --> 00:03:08.210 was followed by profound personal trauma. Immediately 00:03:08.210 --> 00:03:11.069 after graduation, he contracted cholera. Yes. 00:03:11.449 --> 00:03:15.009 He was bedridden for nine agonizing months and 00:03:15.009 --> 00:03:18.330 came close to death several times. His father, 00:03:18.449 --> 00:03:20.930 seeing his son suffering and possibly dying, 00:03:21.050 --> 00:03:23.750 finally broke his long -held insistence that 00:03:23.750 --> 00:03:26.030 Nicola enter the church. This moment of despair 00:03:26.030 --> 00:03:29.740 was pivotal. Tesla, weak but lucid, asked his 00:03:29.740 --> 00:03:31.819 father to promise that if he recovered, he would 00:03:31.819 --> 00:03:33.860 be sent to the best engineering school possible. 00:03:34.120 --> 00:03:36.879 And the father, facing the imminent loss of his 00:03:36.879 --> 00:03:40.219 son, agreed. That promise, made under duress, 00:03:40.259 --> 00:03:43.580 launched his entire career. It did, but his academic 00:03:43.580 --> 00:03:48.259 path quickly grew complex. In 1875, he enrolled 00:03:48.259 --> 00:03:50.979 at the Imperial Royal Technical College in Graz 00:03:50.979 --> 00:03:53.199 on a scholarship. And initially he was extraordinary. 00:03:53.460 --> 00:03:56.219 In his first year, he passed nine exams. Nine. 00:03:56.319 --> 00:03:58.860 Nine, which is almost double the typical requirement. 00:03:59.099 --> 00:04:01.300 The dean sent a letter home complimenting his 00:04:01.300 --> 00:04:03.580 father and calling Nikola a star of first rank. 00:04:03.740 --> 00:04:06.000 A star of the first rank who by his third year 00:04:06.000 --> 00:04:08.219 had lost his scholarship and was engaging in 00:04:08.219 --> 00:04:10.300 behavior that completely derailed his studies. 00:04:10.419 --> 00:04:12.879 What went wrong so quickly? The sources are varied, 00:04:13.000 --> 00:04:15.500 but biographers point to a complete abandonment 00:04:15.500 --> 00:04:18.439 of academic discipline. He reportedly struggled 00:04:18.439 --> 00:04:21.279 with a gambling obsession, particularly pool 00:04:21.279 --> 00:04:24.060 and cards. And womanizing as well. And developed 00:04:24.060 --> 00:04:27.319 a reputation for that, yes. He left Graz in 1878 00:04:27.319 --> 00:04:30.699 without taking any final exams, essentially abandoning 00:04:30.699 --> 00:04:33.319 his degree. Wow. His family was so concerned, 00:04:33.480 --> 00:04:35.319 they feared he had drowned in the Mur River, 00:04:35.480 --> 00:04:38.279 as he cut off all contact. That lack of communication 00:04:38.279 --> 00:04:40.480 is stark. This wasn't just dropping out. This 00:04:40.480 --> 00:04:43.560 was a complete break. It was. His father eventually 00:04:43.560 --> 00:04:45.980 located him working as a draftsman in Maribor, 00:04:46.120 --> 00:04:49.240 earning a small salary. His father tried to insist 00:04:49.240 --> 00:04:51.980 he resume his studies in Prague, but the damage 00:04:51.980 --> 00:04:54.879 was done. So he never got a degree. Never. He 00:04:54.879 --> 00:04:57.259 arrived in Prague too late to enroll, he lacked 00:04:57.259 --> 00:04:59.259 the required preliminary subjects like Greek, 00:04:59.360 --> 00:05:01.899 and he didn't know Czech. He audited philosophy 00:05:01.899 --> 00:05:04.800 lectures for a term, but again, earned no grades, 00:05:04.879 --> 00:05:07.680 received no formal accreditation. So for a man 00:05:07.680 --> 00:05:10.000 who would define the future of engineering, his 00:05:10.000 --> 00:05:13.639 formal academic career ended in, well, in failure. 00:05:13.819 --> 00:05:16.560 Failure and lack of accreditation, yes. Despite 00:05:16.560 --> 00:05:19.060 that lack of a diploma, his talent was undeniable. 00:05:19.259 --> 00:05:22.029 Oh, absolutely. His practical career began in 00:05:22.029 --> 00:05:25.170 Budapest in 1881, working for Tivitar Puskas 00:05:25.170 --> 00:05:28.149 at a telegraph company. He quickly rose to chief 00:05:28.149 --> 00:05:31.050 electrician and made immediate, tangible improvements, 00:05:31.470 --> 00:05:34.149 including a significant enhancement to the telephone 00:05:34.149 --> 00:05:37.029 repeater. This early success in practical application 00:05:37.029 --> 00:05:40.230 rather than academics is telling. It led him 00:05:40.230 --> 00:05:42.449 to the heart of the burgeoning electrical age. 00:05:42.629 --> 00:05:45.889 The Continental Edison Company in Paris in 1882. 00:05:46.149 --> 00:05:49.649 Right. Paris was rapidly electrifying. Tesla 00:05:49.649 --> 00:05:52.750 gained massive hands -on experience, often traveling 00:05:52.750 --> 00:05:55.050 to troubleshoot and install the citywide systems. 00:05:55.250 --> 00:05:57.569 He quickly gained a reputation for innovation. 00:05:57.910 --> 00:05:59.910 And this recognition of his practical skills 00:05:59.910 --> 00:06:02.790 led directly to his pivotal move across the Atlantic. 00:06:03.149 --> 00:06:05.629 In 1884, Charles Batchelor, the Edison manager 00:06:05.629 --> 00:06:08.529 who had observed Tesla's work in Paris, requested 00:06:08.529 --> 00:06:10.970 that he immigrate to America to work at the Edison 00:06:10.970 --> 00:06:13.790 Machine Works in New York City. Tesla arrived 00:06:13.790 --> 00:06:16.550 in the summer of 1884 with a letter of recommendation 00:06:16.550 --> 00:06:19.230 for Thomas Edison and immediately began working 00:06:19.230 --> 00:06:21.629 on Manhattan's Lower East Side. But the culture 00:06:21.629 --> 00:06:24.389 shock was profound. He found the environment 00:06:24.389 --> 00:06:27.990 crowded, dirty, filled with tenements, a painful 00:06:27.990 --> 00:06:30.750 surprise compared to the cosmopolitan orderly 00:06:30.750 --> 00:06:33.050 life he had known in Europe. This clash of environments 00:06:33.050 --> 00:06:34.910 was quickly followed by a clash of commercial 00:06:34.910 --> 00:06:37.709 interests, leading to the infamous Edison breakup. 00:06:37.889 --> 00:06:40.399 They met only briefly. Famously, after Tesla 00:06:40.399 --> 00:06:42.579 pulled an all -nighter to repair damaged dynamos 00:06:42.579 --> 00:06:45.660 on the luxury ocean liner SS Oregon. And Edison 00:06:45.660 --> 00:06:48.459 supposedly remarked, this is a damned good man. 00:06:48.759 --> 00:06:51.420 But the professional relationship deteriorated 00:06:51.420 --> 00:06:54.000 over money. Yes, the central shaping incident 00:06:54.000 --> 00:06:56.860 revolved around a promise of a bonus for redesigning 00:06:56.860 --> 00:06:59.709 Edison's standard machines. And this offer came 00:06:59.709 --> 00:07:01.930 from the manager of the Edison Machine Works. 00:07:02.250 --> 00:07:04.649 Right. Not Edison himself, though Edison was 00:07:04.649 --> 00:07:07.170 likely involved. The manager allegedly offered 00:07:07.170 --> 00:07:10.370 Tesla $50 ,000 for improving the DC generating 00:07:10.370 --> 00:07:12.629 systems. OK, let's put that figure in context 00:07:12.629 --> 00:07:15.930 for you. $50 ,000 in 1885 was a colossal sum. 00:07:16.170 --> 00:07:18.350 Oh, it was. It's equivalent to roughly $1 .75 00:07:18.350 --> 00:07:20.829 million in today's currency. That's generational 00:07:20.829 --> 00:07:23.230 wealth being offered to a 29 -year -old immigrant 00:07:23.230 --> 00:07:27.730 engineer. Precisely. Tesla spent months perfecting 00:07:27.730 --> 00:07:30.160 the generators. When he delivered the improved 00:07:30.160 --> 00:07:34.060 designs, he went to claim his bonus. The response, 00:07:34.180 --> 00:07:36.639 according to Tesla's autobiography, was that 00:07:36.639 --> 00:07:38.860 the manager revoked the offer, stating it was 00:07:38.860 --> 00:07:42.199 merely a practical joke. A practical joke. Can 00:07:42.199 --> 00:07:44.220 you imagine? Regardless of who delivered the 00:07:44.220 --> 00:07:47.120 punchline, the outcome was devastating. That 00:07:47.120 --> 00:07:50.319 betrayal on such a massive financial scale deeply 00:07:50.319 --> 00:07:52.740 cemented his distrust of American commercial 00:07:52.740 --> 00:07:56.009 practices. And financiers, yeah. He quit the 00:07:56.009 --> 00:07:58.509 Edison Machine Works after just six months. His 00:07:58.509 --> 00:08:00.689 diary entry for that final month simply reads, 00:08:00.790 --> 00:08:03.850 Goodbye to the Edison Machine Works. This experience 00:08:03.850 --> 00:08:06.850 fundamentally shaped his later, often disastrous, 00:08:06.889 --> 00:08:09.410 approach to business. Absolutely. He tried to 00:08:09.410 --> 00:08:11.470 immediately leverage his arc lighting patents, 00:08:11.750 --> 00:08:13.990 securing the backing of financiers Robert Lane 00:08:13.990 --> 00:08:17.370 and Benjamin Vail in March 1885. They formed 00:08:17.370 --> 00:08:19.430 the Tesla Electric Light and Manufacturing Company. 00:08:19.879 --> 00:08:22.040 He had developed a highly improved DC generator 00:08:22.040 --> 00:08:24.600 and installed an arc lighting system in Rahway, 00:08:24.740 --> 00:08:27.100 New Jersey. It was a successful product, but 00:08:27.100 --> 00:08:29.399 the business dissolved quickly. Less than a year 00:08:29.399 --> 00:08:34.379 later, in 1886, this was his first crushing entrepreneurial 00:08:34.379 --> 00:08:37.360 failure in America. So why did it collapse when 00:08:37.360 --> 00:08:39.820 the technology itself was successful? The investors 00:08:39.820 --> 00:08:42.360 were purely focused on the immediate, tangible 00:08:42.360 --> 00:08:45.639 profit from the arc lighting utility itself running 00:08:45.639 --> 00:08:48.519 the electricity. I see. They saw no value in 00:08:48.519 --> 00:08:51.470 his... Far more ambitious and disruptive ideas 00:08:51.470 --> 00:08:54.649 for alternating current equipment. When Tesla 00:08:54.649 --> 00:08:57.129 proposed using the profits to develop his AC 00:08:57.129 --> 00:09:00.070 motors and systems, they scoffed. And they took 00:09:00.070 --> 00:09:01.909 the patents with them, leaving him with nothing. 00:09:02.129 --> 00:09:04.889 Absolutely nothing. He had assigned his patents 00:09:04.889 --> 00:09:07.129 to the company for stock, which was now worthless. 00:09:07.429 --> 00:09:10.629 The highly educated, promising engineer was left 00:09:10.629 --> 00:09:12.909 completely penniless in New York. It's just a 00:09:12.909 --> 00:09:15.629 profound humiliation. He was forced to take grueling 00:09:15.629 --> 00:09:18.370 physical work as a ditch digger for only $2 a 00:09:18.370 --> 00:09:21.070 day. He later wrote that his high education in 00:09:21.070 --> 00:09:23.450 various branches of science, mechanics, and literature 00:09:23.450 --> 00:09:26.309 seemed to me like a mockery. Think about that. 00:09:26.450 --> 00:09:29.370 A man capable of reshaping global infrastructure 00:09:29.370 --> 00:09:32.309 was digging trenches for barely enough to survive. 00:09:32.830 --> 00:09:35.769 That period of existential crisis, however, served 00:09:35.769 --> 00:09:39.090 as a final definitive catalyst. The establishment 00:09:39.090 --> 00:09:42.570 Edison, his first financiers, had rejected his 00:09:42.570 --> 00:09:44.909 vision for alternating current. So he decided 00:09:44.909 --> 00:09:47.389 he would dedicate his life to proving them wrong. 00:09:47.590 --> 00:09:50.809 And this devastating failure in 1886 immediately 00:09:50.809 --> 00:09:53.070 preceded the greatest technological transformation 00:09:53.070 --> 00:09:55.409 of his life. The narrative quickly shifts from 00:09:55.409 --> 00:09:58.909 rags to riches. In late 1886, he met Alfred S. 00:09:58.970 --> 00:10:01.590 Brown and Charles Fletcher Peck. Two men who 00:10:01.590 --> 00:10:04.070 saw the potential in his AC ideas and possessed 00:10:04.070 --> 00:10:07.009 the necessary financial and patent savvy. They 00:10:07.009 --> 00:10:09.129 understood the intellectual property game. Which 00:10:09.129 --> 00:10:11.909 Tesla clearly didn't at that point. No. In April 00:10:11.909 --> 00:10:14.210 1887, they formed the Tesla Electric Company, 00:10:14.409 --> 00:10:17.370 establishing a dedicated lab in Manhattan. The 00:10:17.370 --> 00:10:19.309 agreement was structured to fund Tesla's future. 00:10:19.690 --> 00:10:22.389 with profits from patents split three ways. And 00:10:22.389 --> 00:10:24.269 that structure freed Tesla to focus entirely 00:10:24.269 --> 00:10:26.490 on invention. Exactly. And what emerged from 00:10:26.490 --> 00:10:28.690 that Manhattan lab in 1887 was the invention 00:10:28.690 --> 00:10:31.129 that truly changed the world. The AC induction 00:10:31.129 --> 00:10:34.870 motor, patented in May 1888. This was the foundational 00:10:34.870 --> 00:10:37.610 technology for our modern power grid. It was 00:10:37.610 --> 00:10:40.529 revolutionary because it solved the central dilemma 00:10:40.529 --> 00:10:44.230 of AC, how to create constant rotational mechanical 00:10:44.230 --> 00:10:47.629 power using alternating current. Right. Tesla's 00:10:47.629 --> 00:10:49.740 breakthrough. was the use of polyphase current, 00:10:50.019 --> 00:10:53.539 using two or more circuits to carry AC, which 00:10:53.539 --> 00:10:55.899 enabled him to generate a rotating magnetic field. 00:10:56.080 --> 00:10:58.620 Okay, explain that concept for us. What is the 00:10:58.620 --> 00:11:01.379 rotating magnetic field, and why did it matter 00:11:01.379 --> 00:11:05.039 so much? Well, imagine you have two sets of electromagnets 00:11:05.039 --> 00:11:07.320 placed in a circle, powered by two different 00:11:07.320 --> 00:11:10.419 alternating current phases. When phase A reaches 00:11:10.419 --> 00:11:12.899 its peak voltage, the magnetic field is strong 00:11:12.899 --> 00:11:16.129 in one direction. As phase A diminishes, phase 00:11:16.129 --> 00:11:18.470 B is growing, shifting the direction of the magnetic 00:11:18.470 --> 00:11:21.389 field. So the field itself is moving. By alternating 00:11:21.389 --> 00:11:24.169 these peaks and troughs in sequence, the magnetic 00:11:24.169 --> 00:11:26.289 field inside the motor doesn't just pulse on 00:11:26.289 --> 00:11:28.450 and off. It literally rotates smoothly around 00:11:28.450 --> 00:11:30.809 the center of the motor. And that smooth, invisible 00:11:30.809 --> 00:11:33.370 rotation means you don't need any physical moving 00:11:33.370 --> 00:11:36.610 parts to regulate the power. Precisely. The DC 00:11:36.610 --> 00:11:39.370 motor required a commutator, a split ring of 00:11:39.370 --> 00:11:41.649 copper segments that had to physically reverse 00:11:41.649 --> 00:11:44.440 the flow of current every half rotation. Creating 00:11:44.440 --> 00:11:47.379 mechanical wear, heat, and dangerous sparking 00:11:47.379 --> 00:11:49.559 at the brushes. Right. Tesla's motor was self 00:11:49.559 --> 00:11:52.299 -starting, required no commutator, had no brushes, 00:11:52.460 --> 00:11:54.700 and was immensely more durable and efficient 00:11:54.700 --> 00:11:57.500 for industrial use. It was an industrial miracle. 00:11:57.879 --> 00:12:01.480 Silent, low maintenance. and powerful. That successful 00:12:01.480 --> 00:12:05.480 public demonstration in 1888 drew the attention 00:12:05.480 --> 00:12:08.059 of George Westinghouse, who immediately recognized 00:12:08.059 --> 00:12:10.200 that this was the missing link for his existing 00:12:10.200 --> 00:12:13.240 AC lighting system. He knew that whoever controlled 00:12:13.240 --> 00:12:15.799 the AC motor patent would control the future 00:12:15.799 --> 00:12:19.320 of industrial power. No question. In July 1888, 00:12:19.620 --> 00:12:22.440 Westinghouse licensed Tesla's motor and transformer 00:12:22.440 --> 00:12:26.669 designs for a significant sum. $60 ,000 in cash 00:12:26.669 --> 00:12:29.409 and stock. And the crucial royalty agreement 00:12:29.409 --> 00:12:33.889 $2 .50 per AC horsepower produced by every motor. 00:12:34.070 --> 00:12:37.009 If the AC system succeeded that royalty would 00:12:37.009 --> 00:12:38.769 make Tesla one of the richest men in the world. 00:12:38.950 --> 00:12:41.129 Westinghouse also secured his services hiring 00:12:41.129 --> 00:12:43.110 him for a year as a consultant in Pittsburgh 00:12:43.110 --> 00:12:45.809 for $2 ,000 a month. Which is a salary equivalent 00:12:45.809 --> 00:12:48.450 to about $70 ,000 today. But that consulting 00:12:48.450 --> 00:12:51.090 period, it highlighted Tesla's difficulties in 00:12:51.090 --> 00:12:53.529 corporate environments, didn't it? It did. He 00:12:53.529 --> 00:12:56.669 was brilliant, but often rigid. He clashed with 00:12:56.669 --> 00:12:59.129 other Westinghouse engineers who were trying 00:12:59.129 --> 00:13:02.210 to integrate his motor into their system. They 00:13:02.210 --> 00:13:05.230 settled on the 60 -cycle AC system Tesla proposed, 00:13:05.570 --> 00:13:07.610 which is still the standard in North America. 00:13:07.889 --> 00:13:10.350 But the motor itself wasn't suitable for everything. 00:13:10.690 --> 00:13:13.350 No, they found it unsuitable for streetcar traction 00:13:13.350 --> 00:13:15.769 applications because it could only run efficiently 00:13:15.769 --> 00:13:18.789 at a constant speed. They had to continue using 00:13:18.789 --> 00:13:21.769 DC motors for streetcars. This entire development 00:13:21.769 --> 00:13:24.350 occurred within the crucible of the War of Currents. 00:13:24.370 --> 00:13:27.070 This was brutal competition, not only technical, 00:13:27.190 --> 00:13:30.309 but financial and propagandistic. Thomas Edison 00:13:30.309 --> 00:13:33.409 aggressively spent money to promote his DC system. 00:13:33.629 --> 00:13:36.129 Going so far as campaigning publicly that AC 00:13:36.129 --> 00:13:38.889 was lethally dangerous, even using it to power 00:13:38.889 --> 00:13:41.330 the first electric chair. A deliberate act of 00:13:41.330 --> 00:13:44.500 negative publicity. Vicious. and the financial 00:13:44.500 --> 00:13:47.500 pressure on Westinghouse was immense. The company 00:13:47.500 --> 00:13:50.019 had invested heavily in AC, and their debt load 00:13:50.019 --> 00:13:52.720 was significant. And then the financial panic 00:13:52.720 --> 00:13:57.379 of 1890 hits. Exactly. A massive global panic. 00:13:58.159 --> 00:14:00.740 Westinghouse Electric's lenders started calling 00:14:00.740 --> 00:14:03.379 in loans, threatening to dismantle the company. 00:14:03.600 --> 00:14:06.100 And the lenders looked right at Tesla's contract. 00:14:06.649 --> 00:14:08.889 Even though the motor was still being engineered, 00:14:09.190 --> 00:14:12.009 Westinghouse had guaranteed Tesla a minimum royalty 00:14:12.009 --> 00:14:15.330 of $15 ,000 a year. And that payment became a 00:14:15.330 --> 00:14:18.230 huge target for the banks seeking to cut costs. 00:14:18.690 --> 00:14:21.250 George Westinghouse faced losing control of his 00:14:21.250 --> 00:14:24.230 company entirely. So he personally appealed to 00:14:24.230 --> 00:14:27.350 Tesla. He did in 1891. He explained that if the 00:14:27.350 --> 00:14:30.090 company failed, the bankers would take over and 00:14:30.090 --> 00:14:31.950 the future of AC would die with Westinghouse. 00:14:32.169 --> 00:14:34.710 Here's the truly remarkable part of the story. 00:14:35.210 --> 00:14:37.330 The greatest technical act of his career was 00:14:37.330 --> 00:14:39.929 the AC motor, but the greatest commercial act 00:14:39.929 --> 00:14:42.789 was his response to Westinghouse's plea. What 00:14:42.789 --> 00:14:44.929 did he do? He tore up the contract. Just tore 00:14:44.929 --> 00:14:47.129 it up. He agreed to release Westinghouse from 00:14:47.129 --> 00:14:49.470 the guaranteed royalty clause entirely, effectively 00:14:49.470 --> 00:14:51.769 sacrificing what could have been a multi -million 00:14:51.769 --> 00:14:54.629 dollar lifelong income stream. Possibly billions 00:14:54.629 --> 00:14:57.090 in today's valuation. To ensure the survival 00:14:57.090 --> 00:15:00.769 of Westinghouse Electric. He chose the technological 00:15:00.769 --> 00:15:03.870 destiny of AC over his own personal financial 00:15:03.870 --> 00:15:07.269 security. This moves the narrative beyond mere 00:15:07.269 --> 00:15:10.549 altruism. This was Tesla staking the technological 00:15:10.549 --> 00:15:13.809 future of the entire world on the survival of 00:15:13.809 --> 00:15:16.289 one corporation. It was a clear -eyed strategic 00:15:16.289 --> 00:15:19.090 decision born of his deep conviction that AC 00:15:19.090 --> 00:15:22.350 was fundamentally superior. By accepting a much 00:15:22.350 --> 00:15:26.730 smaller lump sum later on, $216 ,000 in 1897, 00:15:27.110 --> 00:15:29.350 he ensured his system won the war of currents. 00:15:29.840 --> 00:15:32.620 With the AC system financially stabilized, Tesla 00:15:32.620 --> 00:15:35.320 moved into a new decade of dazzling scientific 00:15:35.320 --> 00:15:37.720 showmanship. Following his studies of Heinrich 00:15:37.720 --> 00:15:40.179 Hertz's electromagnetic experiments, he developed 00:15:40.179 --> 00:15:42.480 his foundational tool for future wireless work. 00:15:42.679 --> 00:15:45.179 The Tesla coil. The invention that first gave 00:15:45.179 --> 00:15:47.440 him the reputation for creating artificial lightning. 00:15:47.759 --> 00:15:50.259 It was technically a high voltage, low current, 00:15:50.379 --> 00:15:53.440 high frequency oscillating transformer. Standard 00:15:53.440 --> 00:15:55.340 transformers of the time would overheat rapidly 00:15:55.340 --> 00:15:57.679 when pushed to high frequencies. And Tesla's 00:15:57.679 --> 00:15:59.700 breakthrough was recognizing the importance of 00:15:59.700 --> 00:16:02.740 electrical resonance. Yes. He used a carefully 00:16:02.740 --> 00:16:05.399 tuned primary circuit with a large capacitor 00:16:05.399 --> 00:16:08.620 and a spark gap, coupled with a secondary circuit 00:16:08.620 --> 00:16:11.460 with many turns of wire. And that created a powerful 00:16:11.460 --> 00:16:14.679 standing wave. An extremely powerful one. The 00:16:14.679 --> 00:16:16.659 energy was then transferred across an insulating 00:16:16.659 --> 00:16:19.360 air gap to the secondary coil, stepping up the 00:16:19.360 --> 00:16:22.500 voltage to millions of volts. This high frequency, 00:16:22.679 --> 00:16:25.000 high voltage system became his signature tool 00:16:25.000 --> 00:16:27.840 for public demonstration. And the ultimate showcase 00:16:27.840 --> 00:16:31.480 for AC power came at the 1893 World's Columbian 00:16:31.480 --> 00:16:34.360 Exposition in Chicago. This was the crucial turning 00:16:34.360 --> 00:16:37.000 point in the war of currents. Westinghouse won 00:16:37.000 --> 00:16:39.340 the contract to light the entire fair, beating 00:16:39.340 --> 00:16:41.580 out General Electric. And they boldly branded 00:16:41.580 --> 00:16:44.379 their infrastructure as the Tesla polyphase system. 00:16:44.500 --> 00:16:46.940 This was a chance to prove dramatically and visually 00:16:46.940 --> 00:16:50.820 that AC was safe. reliable, and incredibly efficient 00:16:50.820 --> 00:16:53.379 over long distances. And the centerpiece was 00:16:53.379 --> 00:16:56.200 his exhibit on the AC induction motor, featuring 00:16:56.200 --> 00:17:00.039 his spectacular showmanship trick. The egg of 00:17:00.039 --> 00:17:02.399 Columbus. That's right. Using the rotating magnetic 00:17:02.399 --> 00:17:05.019 field, he could cause a copper egg to spin rapidly 00:17:05.019 --> 00:17:08.240 on a table until, against gravity, it stood perfectly 00:17:08.240 --> 00:17:10.960 upright on its major axis. An astonishing visual 00:17:10.960 --> 00:17:13.359 metaphor for the power of polyphase current. 00:17:13.640 --> 00:17:16.900 Which convinced industrial leaders of AC's revolutionary 00:17:16.900 --> 00:17:20.490 potential. And he wowed crowds with his demonstrations 00:17:20.490 --> 00:17:23.769 of wireless lighting. Holding wireless gas discharge 00:17:23.769 --> 00:17:26.609 lamps in his hand, lighting them up just by walking 00:17:26.609 --> 00:17:29.920 across the stage. He confidently told onlookers 00:17:29.920 --> 00:17:31.779 that he was certain a system like this could 00:17:31.779 --> 00:17:34.559 transmit intelligible signals or perhaps even 00:17:34.559 --> 00:17:37.299 power to any distance without the use of wires. 00:17:37.599 --> 00:17:40.619 The final massive validation came that same year. 00:17:40.720 --> 00:17:43.079 With Niagara Falls. When the Cataract Construction 00:17:43.079 --> 00:17:45.720 Company sought advice on transmitting power from 00:17:45.720 --> 00:17:48.019 the newly harnessed falls, Tesla recommended 00:17:48.019 --> 00:17:50.880 the two -phase AC system. And Westinghouse won 00:17:50.880 --> 00:17:53.440 the contract, which officially cemented AC as 00:17:53.440 --> 00:17:55.519 the definitive method for long distance power 00:17:55.519 --> 00:17:57.920 distribution, setting the standard for the entire 00:17:57.920 --> 00:18:00.759 globe. Having successfully commercialized and 00:18:00.759 --> 00:18:03.259 established the AC system, Tesla effectively 00:18:03.259 --> 00:18:06.420 abandoned the corporate world. His focus shifted 00:18:06.420 --> 00:18:09.819 entirely to the grand, ethereal ambition of wireless 00:18:09.819 --> 00:18:12.599 transmission. Leading him to a decade of spectacular 00:18:12.599 --> 00:18:16.460 but commercially isolated experiments. But first, 00:18:16.700 --> 00:18:19.599 a catastrophic event disrupted his work in March 00:18:19.599 --> 00:18:22.759 1895. His South Fifth Avenue laboratory caught 00:18:22.759 --> 00:18:25.619 fire. It was an industrial tragedy. He lost years 00:18:25.619 --> 00:18:28.440 of irreplaceable notes, models, demonstration 00:18:28.440 --> 00:18:30.859 equipment, including the famous pieces from the 00:18:30.859 --> 00:18:33.220 Columbian Exposition. It's devastating to consider 00:18:33.220 --> 00:18:35.500 the scope of that loss. When the New York Times 00:18:35.500 --> 00:18:37.640 asked him about the damage, he could only reply, 00:18:37.940 --> 00:18:41.000 I'm in too much grief to talk. What can I say? 00:18:41.279 --> 00:18:45.930 Imagine your life's work just gone. Yet even 00:18:45.930 --> 00:18:47.910 before that fire, he was exploring completely 00:18:47.910 --> 00:18:51.589 new physics. Starting around 1894, he began investigating 00:18:51.589 --> 00:18:53.950 what he termed radiant energy. After noticing 00:18:53.950 --> 00:18:56.289 damaged photographic plates in his lab. An effect 00:18:56.289 --> 00:18:58.450 he correctly deduced was caused by high energy 00:18:58.450 --> 00:19:01.369 rays. He was on the trail of X -rays before Röntgen's 00:19:01.369 --> 00:19:04.829 major announcement in late 1895. He was. There's 00:19:04.829 --> 00:19:06.789 a wonderful anecdote that he attempted to photograph 00:19:06.789 --> 00:19:09.769 his friend, Mark Twain, illuminated by a gas 00:19:09.769 --> 00:19:12.500 discharge tube. When the plate was developed, 00:19:12.619 --> 00:19:14.720 the only clear image was the metallic locking 00:19:14.720 --> 00:19:17.720 screw on the camera lens. An unintentional x 00:19:17.720 --> 00:19:20.240 -ray image. Predating Roentgen's famous public 00:19:20.240 --> 00:19:22.900 capture. Yes. He was also keenly observant of 00:19:22.900 --> 00:19:25.240 safety, noting the damaging effects on skin and 00:19:25.240 --> 00:19:28.380 tissue. He was. The persistent and painful burns. 00:19:29.119 --> 00:19:31.880 However, in one of his most significant scientific 00:19:31.880 --> 00:19:34.819 errors, he incorrectly attributed this damage 00:19:34.819 --> 00:19:37.500 not to the x -rays themselves, but to the creation 00:19:37.500 --> 00:19:40.490 of ozone and nitrous acid near the skin. While 00:19:40.490 --> 00:19:43.490 exploring these esoteric rays, he produced a 00:19:43.490 --> 00:19:47.490 highly practical, enduring invention, radio remote 00:19:47.490 --> 00:19:51.369 control. In 1898, he demonstrated his teletomaton 00:19:51.369 --> 00:19:53.410 at an electrical exhibition in Madison Square 00:19:53.410 --> 00:19:56.069 Garden. This was a radio -controlled boat, perhaps 00:19:56.069 --> 00:19:58.470 the first functional, wirelessly controlled vehicle 00:19:58.470 --> 00:20:01.150 ever built. It used what was called a coherer 00:20:01.150 --> 00:20:03.170 -based radio system. Which was, you know, an 00:20:03.170 --> 00:20:05.490 extremely early, crude form of radio receiver, 00:20:05.710 --> 00:20:07.569 essentially a tube filled with metal filings. 00:20:07.960 --> 00:20:10.359 When hit by a radio wave, the filings would cohere 00:20:10.359 --> 00:20:13.160 or stick together, completing a circuit. A digital 00:20:13.160 --> 00:20:16.039 on -off switch activated by radio waves. He tried 00:20:16.039 --> 00:20:18.059 to sell the system as a guided torpedo to the 00:20:18.059 --> 00:20:20.619 U .S. military. But they were entirely unconvinced 00:20:20.619 --> 00:20:23.039 by the idea of warfare controlled by magic waves 00:20:23.039 --> 00:20:25.740 and showed little interest. Despite the practical 00:20:25.740 --> 00:20:28.500 success of remote control, Tesla was moving further 00:20:28.500 --> 00:20:31.019 away from conventional communication and deeper 00:20:31.019 --> 00:20:33.799 into his obsession, delivering vast amounts of 00:20:33.799 --> 00:20:36.900 energy wirelessly. And this required him to fundamentally 00:20:36.900 --> 00:20:40.440 reject the prevailing physics of radio, specifically 00:20:40.440 --> 00:20:44.299 the findings of Hertz. Why did Tesla refuse to 00:20:44.299 --> 00:20:46.819 use traditional radio waves for power transmission? 00:20:47.160 --> 00:20:49.980 He believed Hertz had misinterpreted a form of 00:20:49.980 --> 00:20:52.680 electrical conduction as true electromagnetic 00:20:52.680 --> 00:20:56.119 radiation. More importantly, he reasoned that 00:20:56.119 --> 00:20:58.539 traditional radio waves, like any radiation or 00:20:58.539 --> 00:21:01.119 light, spread out in all directions. So the power 00:21:01.119 --> 00:21:03.759 diminishes rapidly with distance. According to 00:21:03.759 --> 00:21:06.700 the inverse square law, yes. He believed the 00:21:06.700 --> 00:21:09.539 energy would be hopelessly lost. into the atmosphere 00:21:09.539 --> 00:21:11.940 and space. The goal, therefore, was not to radiate 00:21:11.940 --> 00:21:14.680 energy, but to conduct it. And to test this incredible, 00:21:14.900 --> 00:21:18.220 audacious hypothesis, he needed space, altitude, 00:21:18.400 --> 00:21:20.779 and a source of massive electrical power. Which 00:21:20.779 --> 00:21:22.400 led him to set up a specialized experimental 00:21:22.400 --> 00:21:26.210 station in Colorado Springs in 1899. Securing 00:21:26.210 --> 00:21:28.410 funding for this massive project was a testament 00:21:28.410 --> 00:21:30.809 to his charisma. He managed to convince John 00:21:30.809 --> 00:21:33.289 Jacob Astor the Firth to invest a substantial 00:21:33.289 --> 00:21:37.369 $100 ,000. Which is nearly $3 .8 million in today's 00:21:37.369 --> 00:21:39.529 dollars. And this was the period of true spectacle 00:21:39.529 --> 00:21:42.250 and intense electrical drama. He was working 00:21:42.250 --> 00:21:45.190 in the megavolts range, generating massive arcs 00:21:45.190 --> 00:21:47.150 that looked like artificial lightning. Up to 00:21:47.150 --> 00:21:50.640 135 feet long. And in one famous incident. The 00:21:50.640 --> 00:21:53.220 massive power drain inadvertently burned out 00:21:53.220 --> 00:21:55.839 the El Paso generator, causing a complete municipal 00:21:55.839 --> 00:21:58.579 power outage. This was the scale of energy he 00:21:58.579 --> 00:22:00.880 was manipulating. And this research also led 00:22:00.880 --> 00:22:03.839 to his famous sensational claims about communication 00:22:03.839 --> 00:22:07.619 from extraterrestrial sources. He observed unusual 00:22:07.619 --> 00:22:11.119 rhythmic signals on his highly sensitive receiver. 00:22:11.609 --> 00:22:13.789 and speculated that these were intelligently 00:22:13.789 --> 00:22:16.569 controlled signals potentially originating from 00:22:16.569 --> 00:22:19.730 Mars or Venus. The press went wild, cementing 00:22:19.730 --> 00:22:22.009 his reputation as a visionary touching the edge 00:22:22.009 --> 00:22:24.769 of science fiction. This episode marked a turning 00:22:24.769 --> 00:22:27.210 point where his public profile began to shift 00:22:27.210 --> 00:22:29.569 from brilliant engineer to prophetic eccentric. 00:22:29.829 --> 00:22:31.750 Armed with the theoretical confirmation from 00:22:31.750 --> 00:22:34.049 Colorado, Tesla returned to New York determined 00:22:34.049 --> 00:22:36.670 to make his world wireless system a reality. 00:22:37.259 --> 00:22:40.500 He knew he needed banking muscle. And he secured 00:22:40.500 --> 00:22:42.500 a meeting with the titan of American finance, 00:22:42.779 --> 00:22:47.079 J .P. Morgan. Morgan provided $150 ,000 in 1901, 00:22:47.160 --> 00:22:51.599 over $5 .7 million today, to build the massive 00:22:51.599 --> 00:22:54.799 Wardenclyffe Tower facility on Long Island. Crucially, 00:22:54.920 --> 00:22:58.059 Morgan received a 51 % stake in any resultant 00:22:58.059 --> 00:23:00.819 wireless patents. The initial agreement was focused 00:23:00.819 --> 00:23:03.559 on intercontinental wireless communication. But 00:23:03.559 --> 00:23:06.000 the underlying vision, the reason Tesla demanded 00:23:06.000 --> 00:23:08.039 such massive scale, was the wireless transmission 00:23:08.039 --> 00:23:10.380 of power. Absolutely. And this was the fatal 00:23:10.380 --> 00:23:13.619 flaw. He was in a race against Guglielmo Marconi, 00:23:13.619 --> 00:23:15.680 who was using the simpler, more conventional 00:23:15.680 --> 00:23:19.299 radio waves. In July 1901, Tesla unilaterally 00:23:19.299 --> 00:23:21.660 expanded his plans for Wardenclyffe, designing 00:23:21.660 --> 00:23:23.859 a vastly more powerful transmitter than originally 00:23:23.859 --> 00:23:26.200 agreed upon. Which rapidly consumed his initial 00:23:26.200 --> 00:23:28.039 funding. And the competitive clock was ticking 00:23:28.039 --> 00:23:31.680 rapidly. It ran out in December 1901. Marconi 00:23:31.680 --> 00:23:33.700 successfully transmitted the letter S across 00:23:33.700 --> 00:23:36.440 the Atlantic from Cornwall, England, to Newfoundland, 00:23:36.500 --> 00:23:38.980 Canada. He achieved transatlantic communication 00:23:38.980 --> 00:23:42.619 first, using a much simpler, cheaper, and faster 00:23:42.619 --> 00:23:44.700 -to -implement system. And Wall Street's interest 00:23:44.700 --> 00:23:48.059 in Tesla evaporated overnight. Investors shifted 00:23:48.059 --> 00:23:50.779 decisively to Marconi's commercial system. And 00:23:50.779 --> 00:23:53.420 Tesla ran out of funds. Unable to explain why 00:23:53.420 --> 00:23:56.740 his much more complicated, expensive power, designed 00:23:56.740 --> 00:23:59.400 not just for communication, but for the secret, 00:23:59.539 --> 00:24:02.299 grander vision of global power, was necessary. 00:24:02.779 --> 00:24:06.000 The press began to label Wardenclyffe a hoax. 00:24:06.319 --> 00:24:08.720 The sheer scale of the engineering hubris involved 00:24:08.720 --> 00:24:11.759 also contributed to its failure, didn't it? Yes, 00:24:11.799 --> 00:24:13.660 the architectural ambition reflected the scope 00:24:13.660 --> 00:24:15.980 of the failure. The tower itself was meant to 00:24:15.980 --> 00:24:18.380 transmit energy through the earth. To achieve 00:24:18.380 --> 00:24:21.220 this, the foundation included a massive subterranean 00:24:21.220 --> 00:24:24.299 structure. A deep metal well and a radial network 00:24:24.299 --> 00:24:26.779 of tunnels. All to ground the transmitter and 00:24:26.779 --> 00:24:29.339 ensure maximum conduction into the earth. This 00:24:29.339 --> 00:24:31.559 underground work alone was ruinously expensive 00:24:31.559 --> 00:24:34.220 and entirely hidden from Morgan. Who only thought 00:24:34.220 --> 00:24:36.619 he was funding a communications platform. Exactly. 00:24:37.140 --> 00:24:40.900 The project halted in 1905. The dream of worldwide 00:24:40.900 --> 00:24:43.880 free energy collapsed on Long Island. The decades 00:24:43.880 --> 00:24:46.039 following the Wardenclyffe collapse were a period 00:24:46.039 --> 00:24:49.099 of intense personal decline, yet still punctuated 00:24:49.099 --> 00:24:51.900 by brilliant, if commercially minor, inventions. 00:24:52.440 --> 00:24:55.119 One of his last major mechanical endeavors was 00:24:55.119 --> 00:24:57.319 the bladeless turbine, which he demonstrated 00:24:57.319 --> 00:25:00.660 on his 50th birthday in 1906. Instead of blades, 00:25:00.740 --> 00:25:03.660 it used smooth rotating discs driven by the viscous 00:25:03.660 --> 00:25:06.599 drag of the working fluid. Right. The prototype 00:25:06.599 --> 00:25:09.980 ran at an incredible 16 ,000 revolutions per 00:25:09.980 --> 00:25:13.140 minute and generated 200 horsepower. That sounds 00:25:13.140 --> 00:25:15.900 like a technical masterpiece. Why didn't it revolutionize 00:25:15.900 --> 00:25:18.460 power generation? While it was incredibly efficient 00:25:18.460 --> 00:25:20.559 at high speed, it struggled with the immense 00:25:20.559 --> 00:25:22.779 physical stresses involved and the metallurgical 00:25:22.779 --> 00:25:25.539 limits of the era. It just wasn't robust enough. 00:25:25.740 --> 00:25:28.259 It found only very limited commercial success. 00:25:28.559 --> 00:25:30.880 Mostly for precision instruments like high -end 00:25:30.880 --> 00:25:33.619 luxury car speedometers. It failed as a solution 00:25:33.619 --> 00:25:36.230 for large -scale power generation. By the mid 00:25:36.230 --> 00:25:39.390 -1910s, with most of his foundational AC patents 00:25:39.390 --> 00:25:42.269 having expired, Tesla was effectively bankrupt. 00:25:42.630 --> 00:25:45.309 It's an almost unbearable paradox. The man who 00:25:45.309 --> 00:25:47.390 powered the world couldn't afford his own accommodation. 00:25:47.829 --> 00:25:50.650 Living a nomadic life between expensive New York 00:25:50.650 --> 00:25:54.250 hotels, the St. Regis, the Waldorf Astoria, the 00:25:54.250 --> 00:25:57.569 Hotel New Yorker, always leaving behind large 00:25:57.569 --> 00:26:00.609 unpaid bills. His financial situation became 00:26:00.609 --> 00:26:03.390 so dire that Westinghouse, the company he had 00:26:03.390 --> 00:26:05.430 saved with his commercial sacrifice years earlier, 00:26:05.630 --> 00:26:09.089 stepped in. Starting in 1934, they began paying 00:26:09.089 --> 00:26:12.250 him $125 per month, plus his rent at the Hotel 00:26:12.250 --> 00:26:14.369 New Yorker. And they were careful to frame it 00:26:14.369 --> 00:26:16.849 as a consulting fee to allow him to maintain 00:26:16.849 --> 00:26:19.609 his pride. But really, it was a stipend. Intended 00:26:19.609 --> 00:26:21.509 to prevent him from becoming a public vagrant. 00:26:22.369 --> 00:26:24.650 Biographers agree that Westinghouse feared the 00:26:24.650 --> 00:26:27.670 bad publicity that would inevitably arise if 00:26:27.670 --> 00:26:29.730 their former star inventor were revealed to be 00:26:29.730 --> 00:26:32.430 living in abject poverty. As his financial situation 00:26:32.430 --> 00:26:35.490 declined, his personal eccentricities grew, fueling 00:26:35.490 --> 00:26:38.190 the mad scientist mythology that persists today. 00:26:38.490 --> 00:26:40.609 He was a lifelong bachelor who publicly claimed 00:26:40.609 --> 00:26:42.910 that maintaining strict chastity was essential 00:26:42.910 --> 00:26:45.089 for focusing his scientific abilities. But the 00:26:45.089 --> 00:26:47.730 most widely known late life eccentricity was 00:26:47.730 --> 00:26:50.130 his obsession with pigeons. He fed the birds 00:26:50.130 --> 00:26:52.289 daily in the parks. This evolved into bringing 00:26:52.289 --> 00:26:54.589 injured birds back to his hotel room for care. 00:26:54.829 --> 00:26:57.470 And he dedicated serious money to this habit, 00:26:57.589 --> 00:27:00.069 didn't he? A phenomenal amount. He was particularly 00:27:00.069 --> 00:27:03.029 obsessed with one injured white pigeon, reportedly 00:27:03.029 --> 00:27:06.130 spending over $2 ,000 to care for it. The equivalent 00:27:06.130 --> 00:27:09.309 of $38 ,000 today. Just to care for this one 00:27:09.309 --> 00:27:12.210 bird. Wow. Even designing a small support device 00:27:12.210 --> 00:27:15.289 to mend its broken wing and leg? This behavior, 00:27:15.430 --> 00:27:17.910 along with the mess, led directly to his eviction 00:27:17.910 --> 00:27:20.440 from multiple hotels. It's a poignant reflection 00:27:20.440 --> 00:27:23.299 on his inability to form deep human connections. 00:27:23.460 --> 00:27:25.500 He was channeling his intensity and engineering 00:27:25.500 --> 00:27:28.559 genius into the care of birds. His other light 00:27:28.559 --> 00:27:31.099 life custom was the annual birthday press conference, 00:27:31.359 --> 00:27:33.460 where he would invite the press and make increasingly 00:27:33.460 --> 00:27:35.559 startling claims about his current projects. 00:27:35.859 --> 00:27:38.579 The claims were astounding. and often lacked 00:27:38.579 --> 00:27:42.339 supporting evidence. In 1932, he claimed to have 00:27:42.339 --> 00:27:45.059 invented a motor that ran purely on cosmic rays. 00:27:45.319 --> 00:27:48.500 In 1933, he went on the attack against the scientific 00:27:48.500 --> 00:27:50.779 establishment. Announcing a new theory of energy 00:27:50.779 --> 00:27:53.680 that was violently opposed to Einsteinian physics, 00:27:53.960 --> 00:27:57.099 he famously dismissed relativity as a beggar 00:27:57.099 --> 00:27:59.720 wrapped in purple. But the most enduring and 00:27:59.720 --> 00:28:01.920 sensational claim was the development of the 00:28:01.920 --> 00:28:05.599 death ray. He announced this superweapon in 1934, 00:28:05.839 --> 00:28:08.759 calling it Teleforce. He presented it as the 00:28:08.759 --> 00:28:11.039 ultimate defensive weapon, powerful enough to 00:28:11.039 --> 00:28:13.859 melt, attacking aircraft and infantry up to 250 00:28:13.859 --> 00:28:16.680 miles away. Claiming it would end all future 00:28:16.680 --> 00:28:19.880 wars by making armies obsolete. He unsuccessfully 00:28:19.880 --> 00:28:22.200 pitched this idea to the U .S. War Department, 00:28:22.440 --> 00:28:25.680 the Soviet Union, and Yugoslavia. So what was 00:28:25.680 --> 00:28:28.359 the technical basis of this teleforce? Was it 00:28:28.359 --> 00:28:30.519 just theoretical bombast, or did he have actual 00:28:30.519 --> 00:28:33.180 plans? The precise nature of the weapon remained 00:28:33.180 --> 00:28:36.759 secret until 1984, when a detailed treatise surfaced 00:28:36.759 --> 00:28:39.259 in the Nikola Tesla Museum archive in Belgrade. 00:28:39.380 --> 00:28:41.519 And it clarified that Teleforce was not a true 00:28:41.519 --> 00:28:44.319 energy ray. No, but a theoretical kinetic energy 00:28:44.319 --> 00:28:46.900 weapon. It detailed an apparatus designed to 00:28:46.900 --> 00:28:49.579 charge slugs of tungsten or mercury to millions 00:28:49.579 --> 00:28:52.079 of volts of electrostatic charge. And these highly 00:28:52.079 --> 00:28:54.400 charged slugs would then be directed and propelled 00:28:54.400 --> 00:28:56.819 in streams via massive electrostatic repulsion. 00:28:57.490 --> 00:29:00.250 Essentially, he theorized a giant electrostatic 00:29:00.250 --> 00:29:02.670 particle accelerator designed to shoot physical 00:29:02.670 --> 00:29:05.430 pellets at high speed, powered by a colossal 00:29:05.430 --> 00:29:08.150 static charge. That distinction is crucial. It 00:29:08.150 --> 00:29:11.349 wasn't a ray gun in the sci -fi sense, but a 00:29:11.349 --> 00:29:14.650 theoretically complex electrostatic cannon. And 00:29:14.650 --> 00:29:17.509 he also made spectacular claims about his mechanical 00:29:17.509 --> 00:29:22.019 oscillator. In 1935, he boasted that an earlier 00:29:22.019 --> 00:29:24.279 version had caused an earthquake in his lower 00:29:24.279 --> 00:29:27.180 Manhattan lab in 1898. And that if the machine 00:29:27.180 --> 00:29:30.000 were properly scaled up, it could destroy the 00:29:30.000 --> 00:29:32.779 Empire State Building with just five pounds of 00:29:32.779 --> 00:29:35.660 air pressure. By finding and exploiting the building's 00:29:35.660 --> 00:29:38.039 resonant frequency. We must also give analytical 00:29:38.039 --> 00:29:41.160 depth to his unique and sometimes jarring philosophical 00:29:41.160 --> 00:29:44.000 views. On physics, he was fundamentally rooted 00:29:44.000 --> 00:29:47.720 in the 19th century worldview. He rigidly adhered 00:29:47.720 --> 00:29:49.799 to the concept of the all -pervasive mechanical 00:29:49.799 --> 00:29:53.059 ether. And this belief put him in direct opposition 00:29:53.059 --> 00:29:55.119 to the great discoveries of the 20th century. 00:29:55.220 --> 00:29:57.819 It did. He fundamentally disagreed with the existence 00:29:57.819 --> 00:30:00.599 of the electron and subatomic particles. His 00:30:00.599 --> 00:30:02.880 adherence to the ether concept meant he absolutely 00:30:02.880 --> 00:30:05.619 rejected Einstein's theory of relativity. Arguing 00:30:05.619 --> 00:30:08.980 that space cannot be curved. For Tesla, space 00:30:08.980 --> 00:30:12.519 and time were absolute. Relativity, which dissolved 00:30:12.519 --> 00:30:15.599 the ether and incorporated curved space, was 00:30:15.599 --> 00:30:18.960 anathema to his entire scientific edifice. And 00:30:18.960 --> 00:30:22.019 he claimed in 1937 that he had solved the fundamental 00:30:22.019 --> 00:30:25.480 mystery of gravity itself. Yes. At age 81, he 00:30:25.480 --> 00:30:28.400 stated he'd completed a dynamic theory of gravity. 00:30:28.829 --> 00:30:31.990 But despite intense searching, no detailed manuscript 00:30:31.990 --> 00:30:34.230 of this theory was ever discovered in his papers. 00:30:34.410 --> 00:30:36.849 Moving a society, his proposed social reforms 00:30:36.849 --> 00:30:39.450 were startlingly severe. He was an advocate for 00:30:39.450 --> 00:30:41.849 eugenics. He was. He believed that human pity 00:30:41.849 --> 00:30:44.630 and aid for the disadvantaged interfered with 00:30:44.630 --> 00:30:46.549 what he called the ruthless workings of nature. 00:30:47.000 --> 00:30:49.920 He argued that by the year 2100, eugenics would 00:30:49.920 --> 00:30:52.160 be universally accepted. An unsettling extension 00:30:52.160 --> 00:30:54.700 of his own obsessive belief in order and efficiency. 00:30:55.099 --> 00:30:57.119 Applied to biological processes, yes. Interestingly, 00:30:57.319 --> 00:30:59.319 he also had provocative views on gender roles. 00:30:59.539 --> 00:31:01.680 He predicted significant shifts in gender dominance. 00:31:01.980 --> 00:31:04.940 In 1926, he foresaw that women, increasingly 00:31:04.940 --> 00:31:07.039 educated and entering the workforce, would soon 00:31:07.039 --> 00:31:09.339 become the dominant sex, the queen bees running 00:31:09.339 --> 00:31:11.460 the world. A striking prediction for the time. 00:31:11.559 --> 00:31:15.210 It was. Tesla's life ended in isolation, mirroring 00:31:15.210 --> 00:31:20.009 his later years. In late 1937, at age 81, he 00:31:20.009 --> 00:31:22.569 was struck by a moving taxicab. He broke three 00:31:22.569 --> 00:31:25.329 ribs and severely wrenched his back. In line 00:31:25.329 --> 00:31:28.230 with his almost lifelong refusal to consult doctors, 00:31:28.410 --> 00:31:31.009 he refused medical attention. He never fully 00:31:31.009 --> 00:31:34.299 recovered. He died alone in his room 3327 at 00:31:34.299 --> 00:31:36.240 the Hotel New Yorker on the night of January 00:31:36.240 --> 00:31:40.099 7, 1943, at the age of 86. His death was officially 00:31:40.099 --> 00:31:42.559 attributed to coronary thrombosis. Given his 00:31:42.559 --> 00:31:44.839 eccentric claims and his knowledge of critical 00:31:44.839 --> 00:31:47.460 power systems, his death immediately triggered 00:31:47.460 --> 00:31:49.839 a national security concern in the U .S. Which 00:31:49.839 --> 00:31:51.539 was, of course, heavily involved in World War 00:31:51.539 --> 00:31:54.319 II. The FBI immediately seized all of his effects, 00:31:54.480 --> 00:31:57.079 concerned that his notes, including a box rumored 00:31:57.079 --> 00:31:59.319 to contain part of the secret death ray, would 00:31:59.319 --> 00:32:02.289 fall into the hands of his nephew and not. They 00:32:02.289 --> 00:32:04.369 brought in an expert to sift through the vast 00:32:04.369 --> 00:32:06.910 collection of papers. Yes, they tasked Dr. John 00:32:06.910 --> 00:32:09.150 G. Trump, an eminent electrical engineer and 00:32:09.150 --> 00:32:11.490 MIT professor and uncle to the future president, 00:32:11.650 --> 00:32:14.809 to analyze the seized materials. And Trump's 00:32:14.809 --> 00:32:16.670 investigation concluded that there was nothing 00:32:16.670 --> 00:32:18.970 in the materials that would constitute a hazard 00:32:18.970 --> 00:32:21.769 in unfriendly hands. The famous death ray box, 00:32:22.069 --> 00:32:24.470 according to Trump's findings, contained only 00:32:24.470 --> 00:32:27.819 a 45 -year -old. multi -decade resistance box. 00:32:28.079 --> 00:32:30.819 An anti -climax. A huge one, but one that cleared 00:32:30.819 --> 00:32:33.700 his name of security concerns. Ultimately, his 00:32:33.700 --> 00:32:36.720 enduring legacy was preserved. His massive archive, 00:32:36.920 --> 00:32:40.579 consisting of over 160 ,000 documents, was shipped 00:32:40.579 --> 00:32:44.160 to Belgrade in 1952. And that archive, alongside 00:32:44.160 --> 00:32:46.640 the approximately 300 patents he holds worldwide, 00:32:46.920 --> 00:32:50.390 definitively secures his place. The eccentricities, 00:32:50.430 --> 00:32:52.289 the failures, and the personal tragedies are 00:32:52.289 --> 00:32:54.809 secondary to the fact that he is the man who 00:32:54.809 --> 00:32:57.410 created the foundation for our entire modern 00:32:57.410 --> 00:33:00.059 electrified infrastructure. What a phenomenal, 00:33:00.240 --> 00:33:02.779 paradoxical life we have traced. We've examined 00:33:02.779 --> 00:33:05.019 Nikola Tesla, the genius who gave us the foundation 00:33:05.019 --> 00:33:07.839 of modern power, but was continually thwarted 00:33:07.839 --> 00:33:10.339 by commercial pressures and his own utopian ambitions. 00:33:10.779 --> 00:33:13.519 Ending his life as a prophetic recluse, meticulously 00:33:13.519 --> 00:33:15.599 caring for pigeons in a New York hotel while 00:33:15.599 --> 00:33:18.440 dreaming of cosmic motors. His career is a definitive 00:33:18.440 --> 00:33:20.559 study in the intersection of engineering vision 00:33:20.559 --> 00:33:23.279 and commercial failure. We saw his peak brilliance 00:33:23.279 --> 00:33:26.619 in the AC motor, the Tesla coil, and remote control. 00:33:27.000 --> 00:33:29.980 but also witnessed his tragic pivot to those 00:33:29.980 --> 00:33:32.680 vast, commercially infeasible, and ultimately 00:33:32.680 --> 00:33:36.019 unfundable projects like Wardenclyffe. This cycle 00:33:36.019 --> 00:33:38.559 brings us back, full circle, to the War of the 00:33:38.559 --> 00:33:42.019 Currents and that pivotal moment in 1891. We 00:33:42.019 --> 00:33:44.019 know the greatest technical act of his life was 00:33:44.019 --> 00:33:47.440 inventing the polyphase AC system. But I want 00:33:47.440 --> 00:33:49.420 to propose this thought for you, the listener, 00:33:49.539 --> 00:33:52.680 to consider. was the greatest act of Nikola Tesla's 00:33:52.680 --> 00:33:55.420 entire career, not the act of invention itself, 00:33:55.759 --> 00:33:58.799 but the deliberate, calculated commercial sacrifice 00:33:58.799 --> 00:34:01.640 he made after the invention. By tearing up the 00:34:01.640 --> 00:34:03.859 royalty contract with George Westinghouse during 00:34:03.859 --> 00:34:07.119 the financial panic of 1890, he stabilized Westinghouse 00:34:07.119 --> 00:34:09.500 Electric, guaranteed the company's survival, 00:34:09.800 --> 00:34:11.780 and ensured that alternating current and not 00:34:11.780 --> 00:34:14.159 direct current, ultimately became the global 00:34:14.159 --> 00:34:16.480 technological standard. He consciously chose 00:34:16.480 --> 00:34:19.300 the destiny of his technology over his own personal 00:34:19.300 --> 00:34:21.920 wealth, potentially sacrificing millions to secure 00:34:21.920 --> 00:34:24.840 the power grid we all use today. Did Nikola Tesla 00:34:24.840 --> 00:34:27.539 define our entire electrical future not through 00:34:27.539 --> 00:34:29.860 his genius, but through his selflessness in the 00:34:29.860 --> 00:34:32.059 face of commercial collapse? It's something to 00:34:32.059 --> 00:34:34.619 consider when you look at the complex, contradictory 00:34:34.619 --> 00:34:38.500 legacy of this true genius. a profound question 00:34:38.500 --> 00:34:41.440 regarding the true cost of technological progress 00:34:41.440 --> 00:34:44.219 thank you for joining us for this deep dive into 00:34:44.219 --> 00:34:46.599 the electrifying life of nikola tesla we'll see 00:34:46.599 --> 00:34:47.059 you next time
