1 00:00:00,560 --> 00:00:03,840 Speaker 1: Welcome to stuff you missed in history class from house 2 00:00:04,120 --> 00:00:13,720 Speaker 1: works dot com. Hello, and welcome to the podcast. I'm 3 00:00:13,720 --> 00:00:16,080 Speaker 1: to bling the Druk reboarding and I'm fared out, and 4 00:00:16,079 --> 00:00:18,639 Speaker 1: we're picking back up here again with our discussion of 5 00:00:18,680 --> 00:00:23,640 Speaker 1: one of our most requested subjects, Nicola Tesla, an engineer 6 00:00:23,640 --> 00:00:26,680 Speaker 1: and an inventor. Tesla's perhaps best known for creating a 7 00:00:26,760 --> 00:00:31,000 Speaker 1: system for delivering electricity using alternating current, a method that 8 00:00:31,200 --> 00:00:33,519 Speaker 1: is still used today. And we talked a little bit 9 00:00:33,520 --> 00:00:36,680 Speaker 1: about the difference between alternating current and direct current and 10 00:00:36,760 --> 00:00:40,240 Speaker 1: their advantages and disadvantages in part one of this podcast. 11 00:00:40,680 --> 00:00:45,120 Speaker 1: And Tesla's preferred alternating current was capable of distributing electricity 12 00:00:45,159 --> 00:00:48,680 Speaker 1: across greater distances than direct current, and he believed that 13 00:00:48,720 --> 00:00:51,199 Speaker 1: it had the potential to be used for more than 14 00:00:51,280 --> 00:00:54,280 Speaker 1: just lighting. But he had some trouble getting support, both 15 00:00:54,320 --> 00:00:57,840 Speaker 1: financial and otherwise for his ideas, at least at first. Yeah, 16 00:00:57,920 --> 00:01:00,400 Speaker 1: and so in the last episode we talked about how 17 00:01:00,440 --> 00:01:03,760 Speaker 1: he came to America, how he approached Edison, armed with 18 00:01:03,840 --> 00:01:07,600 Speaker 1: a recommendation letter from his old boss, Charles Bachelor. The 19 00:01:07,720 --> 00:01:10,920 Speaker 1: letter just said, quote, my dear Edison, I know two 20 00:01:10,959 --> 00:01:13,479 Speaker 1: great men, and you are one of them. The other 21 00:01:13,600 --> 00:01:16,960 Speaker 1: is this young man. It's a pretty great recommendation. Uh. 22 00:01:17,120 --> 00:01:20,120 Speaker 1: Even though Edison, who was a firm believer that direct 23 00:01:20,160 --> 00:01:22,840 Speaker 1: current was not the way to go, shot Tesla down 24 00:01:23,000 --> 00:01:27,319 Speaker 1: on his alternating current ideas on that front, he must 25 00:01:27,319 --> 00:01:30,800 Speaker 1: have agreed with Bachelor's assessment to some degree because he 26 00:01:30,840 --> 00:01:34,040 Speaker 1: did hire Tesla to work for his power company when 27 00:01:34,080 --> 00:01:36,360 Speaker 1: we left off with the story, though Tesla had quit 28 00:01:36,400 --> 00:01:39,160 Speaker 1: working for Edison after just a few months because of 29 00:01:39,160 --> 00:01:43,360 Speaker 1: their personal differences and a little disagreement over money. Tesla 30 00:01:43,400 --> 00:01:45,759 Speaker 1: wanted to strike out on his own at this point 31 00:01:45,760 --> 00:01:48,320 Speaker 1: and develop his own ideas, but when we saw him last, 32 00:01:48,720 --> 00:01:51,280 Speaker 1: his first attempt to do so hadn't worked out so well, 33 00:01:51,320 --> 00:01:54,920 Speaker 1: and he was stuck doing manual labor to survive. So 34 00:01:55,040 --> 00:01:56,960 Speaker 1: Tesla may have been down in the dumps, but he 35 00:01:57,040 --> 00:01:59,920 Speaker 1: stuck fast to his ideas about alternating current and kept 36 00:02:00,040 --> 00:02:03,480 Speaker 1: on trying to get financial backing to make them a reality, 37 00:02:03,800 --> 00:02:06,880 Speaker 1: And in eighteen eighty seven he did manage to attract 38 00:02:06,920 --> 00:02:10,160 Speaker 1: the attention of two investors, Alfred Brown of the Western 39 00:02:10,240 --> 00:02:13,920 Speaker 1: Union Company and Charles Peck, who was an attorney. But 40 00:02:13,960 --> 00:02:17,440 Speaker 1: according to that American Heritage article by Bernard Carlson that 41 00:02:17,480 --> 00:02:20,320 Speaker 1: we mentioned in the Laugh podcast. All Tesla had to 42 00:02:20,360 --> 00:02:23,120 Speaker 1: show them initially was this really crude version of the 43 00:02:23,160 --> 00:02:25,360 Speaker 1: motor he had designed back when he was in Europe, 44 00:02:25,360 --> 00:02:28,080 Speaker 1: and it was basically a shoe polished him that would 45 00:02:28,120 --> 00:02:32,400 Speaker 1: spin around in a big donut shaped coil. So Brown impact, 46 00:02:32,480 --> 00:02:36,000 Speaker 1: they come and look at this creation of of Tesla's 47 00:02:36,000 --> 00:02:38,400 Speaker 1: and they were kind of skeptical of the whole thing. Yeah, 48 00:02:38,440 --> 00:02:41,600 Speaker 1: So to make believers of them, Tesla devised a little 49 00:02:41,639 --> 00:02:45,560 Speaker 1: electrical spectacle which was based on an old legend about 50 00:02:45,639 --> 00:02:49,400 Speaker 1: Christopher Columbus. So, as the story goes, Columbus scott Queen 51 00:02:49,440 --> 00:02:53,160 Speaker 1: Isabella to finance his journey by challenging members of her 52 00:02:53,160 --> 00:02:56,160 Speaker 1: court to balance an egg on one end, And of 53 00:02:56,200 --> 00:02:59,040 Speaker 1: course several people tried and they couldn't do it. So 54 00:02:59,080 --> 00:03:01,680 Speaker 1: then Columbus up and he made the egg stand up 55 00:03:01,720 --> 00:03:05,359 Speaker 1: by gently cracking the shell on one end. Queen Isabella 56 00:03:05,520 --> 00:03:08,399 Speaker 1: was so impressed by his resourceful solution that she gave 57 00:03:08,440 --> 00:03:11,600 Speaker 1: him the funds that he needed. So Tesla asked Brown 58 00:03:11,639 --> 00:03:14,720 Speaker 1: and Peck, who knew of this legend, He said, if 59 00:03:14,720 --> 00:03:17,280 Speaker 1: I can make an egg stand on end without cracking 60 00:03:17,360 --> 00:03:21,360 Speaker 1: the shell will you support these experiments again? According to 61 00:03:21,400 --> 00:03:24,799 Speaker 1: Carlson's article, Peck basically said, yeah, we might. We might 62 00:03:24,880 --> 00:03:26,400 Speaker 1: help you to some extent. We might help you a 63 00:03:26,440 --> 00:03:28,360 Speaker 1: little bit if that were to happen. So Tesla came 64 00:03:28,400 --> 00:03:31,480 Speaker 1: back with a copper plated egg and his donut coil 65 00:03:31,600 --> 00:03:34,880 Speaker 1: attached to the underside of a wooden table. When Tesla 66 00:03:34,920 --> 00:03:38,600 Speaker 1: applied alternating current to that coil, the egg not only 67 00:03:38,600 --> 00:03:42,200 Speaker 1: stood on end, but it started spinning. Then it flipped 68 00:03:42,280 --> 00:03:44,600 Speaker 1: up and started rotating on its axis. I mean it 69 00:03:44,600 --> 00:03:47,840 Speaker 1: looks like a magic trick. So better than a shoe 70 00:03:47,840 --> 00:03:50,640 Speaker 1: polished tin. Right, much better than a shoe polished tin. 71 00:03:50,840 --> 00:03:53,200 Speaker 1: And Brown and Peck were so impressed that they agreed 72 00:03:53,240 --> 00:03:56,560 Speaker 1: to back his work. So with their help, Tesla was 73 00:03:56,680 --> 00:03:59,280 Speaker 1: able to set up a laboratory in Lower Manhattan and 74 00:03:59,600 --> 00:04:03,280 Speaker 1: perf all the components of his alternating current system, and 75 00:04:03,600 --> 00:04:06,400 Speaker 1: that same year he built the prototype for his polyphase 76 00:04:06,480 --> 00:04:10,760 Speaker 1: induction motor. And the problem with alternating current systems before 77 00:04:10,840 --> 00:04:13,960 Speaker 1: this had been that there wasn't really a workable motor 78 00:04:14,040 --> 00:04:18,360 Speaker 1: that alternating current could power. So Tesla's motor solved that 79 00:04:18,480 --> 00:04:20,479 Speaker 1: issue at least and then again with the help of 80 00:04:20,520 --> 00:04:24,440 Speaker 1: Peck and Brown. In late he was able to secure 81 00:04:24,720 --> 00:04:29,560 Speaker 1: seven more patents for a complete alternating current system based 82 00:04:29,600 --> 00:04:34,920 Speaker 1: on this induction motor, including patents for generators, transformers, transmission lines, 83 00:04:35,320 --> 00:04:39,440 Speaker 1: and lighting. So he had the whole set. Finally, there 84 00:04:39,600 --> 00:04:43,000 Speaker 1: was still that little detail of getting these breakthrough ideas 85 00:04:43,120 --> 00:04:48,320 Speaker 1: introduced commercially though. I mean, you have the technology, great, 86 00:04:48,440 --> 00:04:50,960 Speaker 1: you have the patents, that's great, but how are you 87 00:04:51,000 --> 00:04:53,360 Speaker 1: going to actually make money off of it? So that 88 00:04:53,440 --> 00:04:56,400 Speaker 1: process started to take off the next year after Tesla 89 00:04:56,440 --> 00:04:59,920 Speaker 1: demonstrated his alternating current motor at the meeting of the 90 00:05:00,040 --> 00:05:04,279 Speaker 1: American Institute of Electrical Engineers, and that demonstration caught the 91 00:05:04,360 --> 00:05:09,000 Speaker 1: eye of George Westinghouse. Westinghouse's company, which was based in Pittsburgh, 92 00:05:09,279 --> 00:05:13,279 Speaker 1: had successfully developed some safety components for rail transportation, including 93 00:05:13,279 --> 00:05:16,040 Speaker 1: the air brake, and by eight eight or so, he'd 94 00:05:16,040 --> 00:05:19,520 Speaker 1: become interested in getting in on the electricity transmission game. 95 00:05:20,080 --> 00:05:23,080 Speaker 1: According to the article by Ronald Bailey in American History, 96 00:05:23,120 --> 00:05:26,720 Speaker 1: which we referenced in the last podcast, Westinghouse had already 97 00:05:26,720 --> 00:05:30,120 Speaker 1: set up a limited alternating current system, but it was 98 00:05:30,160 --> 00:05:33,320 Speaker 1: confined to downtown Buffalo, New York, and he was attracted 99 00:05:33,320 --> 00:05:36,560 Speaker 1: to that potential of Tesla system to distribute power over 100 00:05:36,640 --> 00:05:40,160 Speaker 1: longer distances, so Westinghouse made a move. He offered to 101 00:05:40,240 --> 00:05:44,200 Speaker 1: buy Tesla's patents, and again Pack and Brown helped Tesla 102 00:05:44,240 --> 00:05:47,640 Speaker 1: negotiate this deal, and the deal is slightly different depending 103 00:05:47,680 --> 00:05:50,440 Speaker 1: on what stores you look at, but it basically amounted 104 00:05:50,480 --> 00:05:55,039 Speaker 1: to Westinghouse paying about sixty thousand to seventy thousand dollars 105 00:05:55,080 --> 00:05:58,480 Speaker 1: and anywhere from five thousand to twenty thousand dollars if 106 00:05:58,480 --> 00:06:01,160 Speaker 1: that was paid in cash. He also agreed to pay 107 00:06:01,240 --> 00:06:04,680 Speaker 1: Tesla two dollars and fifty cents in royalties for each 108 00:06:04,760 --> 00:06:09,559 Speaker 1: horsepower of developed electrical capacity, so according to Bailey's article, 109 00:06:09,600 --> 00:06:13,040 Speaker 1: Westinghouse also agreed to a minimum of thirty thousand in 110 00:06:13,120 --> 00:06:16,160 Speaker 1: royalties to be paid over the next three years, and 111 00:06:16,240 --> 00:06:19,760 Speaker 1: according to PBS dot Org, Tesla got one hundred fifty 112 00:06:19,880 --> 00:06:23,120 Speaker 1: years of Westinghouse stock in the deal, so there was 113 00:06:23,160 --> 00:06:26,480 Speaker 1: a lot covering um. I don't know depending on how 114 00:06:26,680 --> 00:06:31,560 Speaker 1: successful the implementation of the ideas was how much Tesla 115 00:06:31,560 --> 00:06:34,560 Speaker 1: would benefit from that. When the deal was done, Tesla 116 00:06:34,600 --> 00:06:37,720 Speaker 1: went off to work as a Westinghouse consultant and helped 117 00:06:37,760 --> 00:06:40,400 Speaker 1: develop the Alternating Current system for commercial use. So not 118 00:06:40,440 --> 00:06:42,839 Speaker 1: only did he get some money out of the deal 119 00:06:42,880 --> 00:06:45,159 Speaker 1: and potential for more money, but he also got to 120 00:06:45,720 --> 00:06:49,880 Speaker 1: still work with his invention Westinghouse engineers, though just as 121 00:06:49,920 --> 00:06:52,679 Speaker 1: an aside, a little side note here, they didn't really 122 00:06:52,680 --> 00:06:56,280 Speaker 1: love working with Tesla though. He didn't make real blueprints. 123 00:06:56,279 --> 00:06:58,200 Speaker 1: He just had these sketches that he made in a 124 00:06:58,240 --> 00:07:01,679 Speaker 1: tiny notebook and they were really hard to follow. And 125 00:07:02,279 --> 00:07:04,920 Speaker 1: Tesla himself said, well, I can just give you the 126 00:07:05,080 --> 00:07:07,919 Speaker 1: measurements and they will be exactly what you need to 127 00:07:07,960 --> 00:07:12,640 Speaker 1: build this. But as you might imagine, these engineers, yeah, 128 00:07:12,640 --> 00:07:17,720 Speaker 1: I mean interestingly, also, Tesla had always said that he 129 00:07:17,920 --> 00:07:22,560 Speaker 1: just created this induction motor from like as he had 130 00:07:22,680 --> 00:07:26,560 Speaker 1: envisioned it in Europe before he came to America, is 131 00:07:26,560 --> 00:07:29,320 Speaker 1: exactly how he built it. Like, he didn't develop it. 132 00:07:29,360 --> 00:07:31,560 Speaker 1: You might imagine this going through like many revisions and 133 00:07:31,600 --> 00:07:34,800 Speaker 1: many changes, but a prototype or something, yes, exactly. But 134 00:07:34,880 --> 00:07:36,720 Speaker 1: he said that he just made it as soon as 135 00:07:36,720 --> 00:07:38,680 Speaker 1: he saw it in his mind. He knew that that 136 00:07:38,760 --> 00:07:41,880 Speaker 1: was like composers who say that they just heard it 137 00:07:41,920 --> 00:07:44,560 Speaker 1: in their head and wrote it down exactly. He claimed 138 00:07:44,600 --> 00:07:47,000 Speaker 1: that exactly as he saw it is how he built it, 139 00:07:47,040 --> 00:07:50,520 Speaker 1: and it was meant to work. But these engineers they 140 00:07:50,560 --> 00:07:53,760 Speaker 1: also disagreed with Tesla over what the motors frequency should be, 141 00:07:53,840 --> 00:07:56,320 Speaker 1: but Tesla one out with the sixty cycles per second, 142 00:07:56,480 --> 00:07:58,800 Speaker 1: so Tesla had the final day in that regard. But 143 00:07:58,880 --> 00:08:01,720 Speaker 1: this was where the full on current war really started 144 00:08:01,720 --> 00:08:04,960 Speaker 1: to take off, and it was a battle between Westinghouses 145 00:08:05,000 --> 00:08:08,960 Speaker 1: alternating current and Edison's direct current. And what was really 146 00:08:09,000 --> 00:08:11,920 Speaker 1: at stake here was whose system was going to become 147 00:08:11,920 --> 00:08:16,800 Speaker 1: the standard and fuel the development of electricity in the future. Edison, though, 148 00:08:16,800 --> 00:08:18,960 Speaker 1: of course, had a bit of an edge going in 149 00:08:19,040 --> 00:08:23,200 Speaker 1: since he already had about one power stations in operation 150 00:08:23,320 --> 00:08:28,160 Speaker 1: compared to Westinghouses stations. But as we've mentioned a few times, 151 00:08:28,240 --> 00:08:32,920 Speaker 1: Testla's alternating current system showed more promise for carrying electricity 152 00:08:32,960 --> 00:08:36,680 Speaker 1: over long distances, whereas Edison's direct current had a range 153 00:08:36,679 --> 00:08:38,680 Speaker 1: of only about a mile, so it seems like it 154 00:08:38,679 --> 00:08:42,320 Speaker 1: was going to have more limited applications. Also, alternating current 155 00:08:42,360 --> 00:08:45,120 Speaker 1: was a lot cheaper because direct current required the use 156 00:08:45,200 --> 00:08:49,839 Speaker 1: of these expensive copper wires, and alternating current systems used 157 00:08:49,960 --> 00:08:52,960 Speaker 1: copper as well, but only about a third of the 158 00:08:53,000 --> 00:08:57,319 Speaker 1: amount that direct current used, So it looked like Westinghouse 159 00:08:57,360 --> 00:09:01,160 Speaker 1: and alternating current might provide some serious competition for Edison, 160 00:09:01,520 --> 00:09:04,040 Speaker 1: and Edison stepped up his game at that point by 161 00:09:04,240 --> 00:09:08,520 Speaker 1: starting a propaganda campaign against alternating current. He focused in 162 00:09:08,559 --> 00:09:12,640 Speaker 1: this campaign on his own belief that alternating current was unsafe, 163 00:09:13,000 --> 00:09:15,800 Speaker 1: so he started to spread around the idea that alternating 164 00:09:15,840 --> 00:09:19,200 Speaker 1: current and its high voltages could actually kill you. The 165 00:09:19,240 --> 00:09:21,679 Speaker 1: most direct current could do, he said, was just give 166 00:09:21,720 --> 00:09:25,160 Speaker 1: you a little shock. Edison even hired a professor named 167 00:09:25,200 --> 00:09:28,120 Speaker 1: Harold Brown to go around and lecture on the dangerous 168 00:09:28,120 --> 00:09:32,199 Speaker 1: of alternating current, and these talks included things like public 169 00:09:32,200 --> 00:09:37,439 Speaker 1: electrocution of animals, including dogs, cats, horses, and cows. Edison 170 00:09:37,520 --> 00:09:40,559 Speaker 1: even had an elephant named Topsy electrocuted once to prove 171 00:09:40,640 --> 00:09:43,520 Speaker 1: his point. We've had a tragic run for elephant from 172 00:09:43,520 --> 00:09:47,199 Speaker 1: the podcast between This and P. T. Barnum. But Edison 173 00:09:47,280 --> 00:09:51,640 Speaker 1: made his biggest point August when Brown helped New York's 174 00:09:51,679 --> 00:09:55,800 Speaker 1: Auburn State Prison perform the first execution by electric chair. 175 00:09:55,920 --> 00:10:00,120 Speaker 1: And according to PBS, Brown had obtained Westinghouse technolog the 176 00:10:00,280 --> 00:10:03,240 Speaker 1: illegally to build the chair. I mean, you can imagine 177 00:10:03,240 --> 00:10:06,440 Speaker 1: Westinghouse would not have wanted his work associated with that. 178 00:10:06,960 --> 00:10:10,280 Speaker 1: Um the man who was executed was the convicted murderer 179 00:10:10,280 --> 00:10:15,000 Speaker 1: William Kemmler. His death was described as quote an awful spectacle, 180 00:10:15,160 --> 00:10:20,280 Speaker 1: worse than hanging, and thereafter electrocution was known as Westinghouse 181 00:10:20,280 --> 00:10:25,520 Speaker 1: being though really bad pr for alternating current Yeah. Despite 182 00:10:25,520 --> 00:10:29,640 Speaker 1: these negative associations, though, team Westinghouse and Tesla started to 183 00:10:29,679 --> 00:10:32,960 Speaker 1: come up with some winds. They were picked to illuminate 184 00:10:33,160 --> 00:10:37,240 Speaker 1: the Chicago World's Fair, for example, which was also of 185 00:10:37,240 --> 00:10:40,080 Speaker 1: course known as the Columbian Exposition, something we discussed a 186 00:10:40,080 --> 00:10:43,480 Speaker 1: little in the H. H. Holmes podcast indeed, and if 187 00:10:43,600 --> 00:10:46,559 Speaker 1: you pick up Eric Larson's book Devil in the White City, 188 00:10:46,600 --> 00:10:48,520 Speaker 1: you'll learn a little bit more about kind of some 189 00:10:48,559 --> 00:10:50,920 Speaker 1: of the things we're about to talk about. But this 190 00:10:51,080 --> 00:10:54,360 Speaker 1: was the first all electric World's Fair in history, and 191 00:10:54,400 --> 00:10:57,000 Speaker 1: Westinghouse has bid ended up winning out here just because 192 00:10:57,120 --> 00:10:59,040 Speaker 1: it was so much cheaper. It was about half as 193 00:10:59,120 --> 00:11:01,680 Speaker 1: much as the competition shan And in Bailey's article he 194 00:11:01,720 --> 00:11:04,560 Speaker 1: talks about how the fair became this grand showcase for 195 00:11:05,000 --> 00:11:08,040 Speaker 1: alternating currents and electricity in general, so it turned out 196 00:11:08,040 --> 00:11:10,440 Speaker 1: to be a really good win for them, and Testla 197 00:11:10,559 --> 00:11:13,880 Speaker 1: system lit up something like one and eighty thousand bulbs 198 00:11:13,960 --> 00:11:17,240 Speaker 1: and it was used to power a lot of exhibits, 199 00:11:17,280 --> 00:11:19,880 Speaker 1: and there was even a great Hall of Electricity where 200 00:11:19,880 --> 00:11:23,720 Speaker 1: his system was displayed, and Tesla was even on display 201 00:11:23,760 --> 00:11:26,400 Speaker 1: to some degree. He did a demonstration in which he 202 00:11:27,080 --> 00:11:30,840 Speaker 1: sent two hundred thousand volts through his body while wearing 203 00:11:30,920 --> 00:11:33,640 Speaker 1: cork sold shoes for protection. So don't get too worried. 204 00:11:34,000 --> 00:11:36,160 Speaker 1: But he sent these volts through his body to prove 205 00:11:36,240 --> 00:11:39,240 Speaker 1: basically that alternating current was indeed safe. And I can 206 00:11:39,240 --> 00:11:41,559 Speaker 1: see how that would be more compelling combined with the 207 00:11:41,800 --> 00:11:46,240 Speaker 1: glowing white city too, then seeing an elephant electrocuted or 208 00:11:46,480 --> 00:11:49,839 Speaker 1: somebody put in an electric chair, somebody surviving this and 209 00:11:50,640 --> 00:11:54,040 Speaker 1: demonstrating it really is okay if it's handled properly. Yeah, 210 00:11:54,080 --> 00:11:55,839 Speaker 1: if you're willing to do it on yourself, then you 211 00:11:55,920 --> 00:11:59,080 Speaker 1: must have some faith in it. But after the fair, 212 00:11:59,120 --> 00:12:03,200 Speaker 1: according to p. B Quote, of all the electrical devices 213 00:12:03,320 --> 00:12:07,480 Speaker 1: ordered in the United States were for alternating current. And this, 214 00:12:07,679 --> 00:12:11,160 Speaker 1: of course that the stage for another big win in 215 00:12:11,200 --> 00:12:14,360 Speaker 1: the current War, which was a contract with the Niagara 216 00:12:14,440 --> 00:12:18,360 Speaker 1: Falls Commission and mcmission wanted the Westinghouse Company to use 217 00:12:18,400 --> 00:12:22,040 Speaker 1: alternating current to harness the power of the falls to 218 00:12:22,080 --> 00:12:25,839 Speaker 1: generate electricity and This was the realization of a long 219 00:12:25,920 --> 00:12:28,360 Speaker 1: time dream for Tesla. As we mentioned in part one, 220 00:12:28,679 --> 00:12:31,559 Speaker 1: he had started dreaming about converting the power of water 221 00:12:31,640 --> 00:12:34,280 Speaker 1: to electricity when he was only about five years old, 222 00:12:34,400 --> 00:12:38,959 Speaker 1: and he had specifically thought about Niagara Falls at some point. 223 00:12:39,040 --> 00:12:42,400 Speaker 1: And it did take several years to get the project completed, 224 00:12:42,480 --> 00:12:45,360 Speaker 1: which was a situation that made investors pretty nervous. But 225 00:12:45,440 --> 00:12:49,760 Speaker 1: on the night of November they flipped a switch and 226 00:12:49,840 --> 00:12:54,040 Speaker 1: by midnight the Niagara systems were providing power to the 227 00:12:54,040 --> 00:12:57,080 Speaker 1: city of Buffalo, which was twenty six miles away. The 228 00:12:57,080 --> 00:13:00,520 Speaker 1: Buffalo Enquirer wrote, quote, it was the journey of God's 229 00:13:00,600 --> 00:13:04,280 Speaker 1: own lightning to the employee of man. In a few years, 230 00:13:04,360 --> 00:13:08,000 Speaker 1: there were ten enormous generators at Niagara Falls, and according 231 00:13:08,000 --> 00:13:11,600 Speaker 1: to Bailey's article, of all the electricity in the United 232 00:13:11,640 --> 00:13:14,559 Speaker 1: States came from there, including all the power that lit 233 00:13:14,600 --> 00:13:16,960 Speaker 1: up in New York City and Broadway and all of that. 234 00:13:17,360 --> 00:13:21,240 Speaker 1: And even the Edison systems converted to alternating currents after that. 235 00:13:21,520 --> 00:13:24,800 Speaker 1: So with that about face on Edison's part, it seemed 236 00:13:24,840 --> 00:13:28,280 Speaker 1: that Tesla and Westinghouse had won the war of the currents. 237 00:13:28,280 --> 00:13:32,360 Speaker 1: But the inventor had made some significant sacrifices along the 238 00:13:32,400 --> 00:13:35,280 Speaker 1: way too, though, and during the financial panic of the 239 00:13:35,360 --> 00:13:40,079 Speaker 1: eight nineties, Westinghouse and Edison's company were both in trouble, 240 00:13:40,200 --> 00:13:43,200 Speaker 1: and on top of this, seeing the money making potential 241 00:13:43,200 --> 00:13:46,920 Speaker 1: of hydroelectric power, some Wall Street forces like JP Morgan 242 00:13:47,040 --> 00:13:50,280 Speaker 1: he's been popping up in podcast lately, tried to take 243 00:13:50,320 --> 00:13:55,000 Speaker 1: over Westinghouse. So Westinghouse the Man asked Tesla to release 244 00:13:55,080 --> 00:13:59,319 Speaker 1: him from the initial contract that gave Tesla those generous royalties, 245 00:13:59,360 --> 00:14:03,440 Speaker 1: and heflin generously agreed to give up future royalties and 246 00:14:03,480 --> 00:14:07,520 Speaker 1: supposedly even tore up the contract. Um. He might wonder, 247 00:14:07,559 --> 00:14:10,800 Speaker 1: considering the problems he had had making money off of 248 00:14:10,920 --> 00:14:14,199 Speaker 1: his work earlier, why he would do that, But according 249 00:14:14,240 --> 00:14:17,480 Speaker 1: to PBS, he was very grateful to this one man 250 00:14:17,600 --> 00:14:20,720 Speaker 1: who had believed in his invention, and this was his 251 00:14:20,760 --> 00:14:23,400 Speaker 1: way of showing how grateful he was. He also just 252 00:14:23,520 --> 00:14:26,560 Speaker 1: probably wanted them to keep going. I would imagine instead 253 00:14:26,560 --> 00:14:30,440 Speaker 1: of going under, let's save the Westinghouse Electric Company while 254 00:14:30,560 --> 00:14:35,160 Speaker 1: Edison's own company was taken over by General Electric. Tesla, though, 255 00:14:35,280 --> 00:14:37,880 Speaker 1: had trouble with finances for pretty much the rest of 256 00:14:37,920 --> 00:14:41,640 Speaker 1: his life, so it could have used the royalty. Yeah, 257 00:14:41,680 --> 00:14:44,400 Speaker 1: it's sort of a poignant thinking about those royalties gone 258 00:14:44,440 --> 00:14:47,240 Speaker 1: away and and how much money he could have made 259 00:14:47,240 --> 00:14:50,400 Speaker 1: down the line. But it wasn't for lack of trying though. 260 00:14:50,440 --> 00:14:53,200 Speaker 1: Tesla did keep on experimenting, and he was convinced that 261 00:14:53,240 --> 00:14:56,240 Speaker 1: there were more amazing inventions on the horizon, And so 262 00:14:56,320 --> 00:14:59,160 Speaker 1: we want to talk about some of the other things 263 00:14:59,200 --> 00:15:01,880 Speaker 1: that he did even while the so called current war 264 00:15:02,000 --> 00:15:04,680 Speaker 1: was going on. Of course, we can't cover everything. There 265 00:15:04,680 --> 00:15:08,320 Speaker 1: are just so many inventions and patents to to cover, 266 00:15:08,480 --> 00:15:11,040 Speaker 1: and so many ideas to cover that you know, maybe 267 00:15:11,040 --> 00:15:15,320 Speaker 1: didn't get patents or didn't um immediately inspire inventions. But 268 00:15:15,360 --> 00:15:16,880 Speaker 1: we're just going to go over a few of those. 269 00:15:17,360 --> 00:15:20,080 Speaker 1: He had invented what we now know as the Tesla 270 00:15:20,120 --> 00:15:23,600 Speaker 1: coil in eighteen nine, and this basically allowed him to 271 00:15:23,600 --> 00:15:27,320 Speaker 1: take the ordinary sixty cycle per second household current and 272 00:15:27,520 --> 00:15:29,520 Speaker 1: kind of kick it up a few notches into the 273 00:15:29,640 --> 00:15:32,560 Speaker 1: hundreds of thousands of cycles per second, so maybe more 274 00:15:32,600 --> 00:15:35,640 Speaker 1: than a few notches. So this let him experiment with 275 00:15:35,720 --> 00:15:38,640 Speaker 1: high frequency electricity, which was a big interest of his 276 00:15:38,760 --> 00:15:41,560 Speaker 1: for a while, and that in turn allowed him to 277 00:15:41,640 --> 00:15:45,120 Speaker 1: create the first neot lights and the first fluorescent lights, 278 00:15:45,160 --> 00:15:49,080 Speaker 1: and He also took the first X ray photographs, another 279 00:15:49,120 --> 00:15:51,720 Speaker 1: obsession of his which really stuck with him to the 280 00:15:51,840 --> 00:15:55,400 Speaker 1: end with the wireless transmission of energy, and he discovered 281 00:15:55,400 --> 00:15:57,560 Speaker 1: in the early eighteen nineties that he could use his 282 00:15:57,640 --> 00:16:01,360 Speaker 1: Tesla coils to send and receive radio signals, but a 283 00:16:01,440 --> 00:16:05,320 Speaker 1: lab fire in eighteen destroyed his work before he could 284 00:16:05,720 --> 00:16:09,360 Speaker 1: truly test this, and that was just the little bit 285 00:16:09,400 --> 00:16:12,400 Speaker 1: of delay that really messed him up here. Yes, Tesla 286 00:16:12,480 --> 00:16:15,720 Speaker 1: did end up filing for radio patents in eighteen ninety seven, 287 00:16:15,720 --> 00:16:18,880 Speaker 1: but by this time he had a competitor across the pond, 288 00:16:19,080 --> 00:16:24,000 Speaker 1: Guielmo Marconi. Marconi had been granted a wireless communication patent 289 00:16:24,040 --> 00:16:26,600 Speaker 1: in England in eighteen ninety six, and he tried to 290 00:16:26,640 --> 00:16:29,640 Speaker 1: file for a patent in American nineteen hundred, but it 291 00:16:29,680 --> 00:16:32,640 Speaker 1: was turned down at that point because of Tesla's existing patent. 292 00:16:33,240 --> 00:16:35,960 Speaker 1: But in late nineteen o one, Marconi became the first 293 00:16:36,040 --> 00:16:39,680 Speaker 1: to transmit and receive signals across the Atlantic Ocean. Tesla 294 00:16:39,760 --> 00:16:42,680 Speaker 1: to take that turn pretty well. Um Otis Pond, who 295 00:16:42,720 --> 00:16:45,480 Speaker 1: is an engineer working for Tesla at the time, said 296 00:16:45,520 --> 00:16:47,880 Speaker 1: to him a quote, looks as if Marconi got the 297 00:16:47,960 --> 00:16:51,680 Speaker 1: jump on you. To which Tesla replied, quote, Marconi is 298 00:16:51,720 --> 00:16:55,120 Speaker 1: a good fellow. Let him continue. He is using seventeen 299 00:16:55,160 --> 00:16:57,800 Speaker 1: of my patents. No one could accuse him of lack 300 00:16:57,840 --> 00:17:00,680 Speaker 1: of confidence. But he was singing a different tune in 301 00:17:00,760 --> 00:17:04,600 Speaker 1: nineteen o four, when inexplicably the U. S. Patent Office 302 00:17:04,720 --> 00:17:08,160 Speaker 1: changed its mind and gave Marconi the patent for inventing 303 00:17:08,200 --> 00:17:11,600 Speaker 1: the radio. Marconi also ended up winning the Nobel Prize 304 00:17:11,640 --> 00:17:15,800 Speaker 1: in nineteen o nine, and Tesla was really unhappy about this. 305 00:17:15,960 --> 00:17:19,480 Speaker 1: I mean he was angry, but he didn't have the cash. 306 00:17:19,520 --> 00:17:22,000 Speaker 1: You get involved in a patent infringement case. He wanted 307 00:17:22,040 --> 00:17:23,840 Speaker 1: to he wanted to sue, but then he was like, 308 00:17:23,880 --> 00:17:26,280 Speaker 1: I don't really have the ability to carry this out. 309 00:17:27,000 --> 00:17:30,600 Speaker 1: Tesla continued to experiment with the wireless transmission of energy, 310 00:17:30,640 --> 00:17:33,680 Speaker 1: and in eight he made a demonstration of the world's 311 00:17:33,760 --> 00:17:37,560 Speaker 1: first radio controlled vessel at an electrical exhibition in Madison 312 00:17:37,600 --> 00:17:40,240 Speaker 1: Square Garden. It was basically a toy boat that was 313 00:17:40,320 --> 00:17:43,720 Speaker 1: manipulated by remote control. Yeah, and as a side note here, 314 00:17:43,720 --> 00:17:46,760 Speaker 1: many people think of this as the birth of robotics. 315 00:17:46,880 --> 00:17:50,600 Speaker 1: Tesla hoped that it would eventually lighten the workload of humans. 316 00:17:50,640 --> 00:17:52,119 Speaker 1: I mean, it was a toy boat for now, but 317 00:17:52,160 --> 00:17:54,840 Speaker 1: it could be something more in the future. So in 318 00:17:54,880 --> 00:17:58,679 Speaker 1: the late eighteen nineties, Tesla also began to experiment with 319 00:17:58,720 --> 00:18:02,320 Speaker 1: the transmission of elect iCal power without wires, and in 320 00:18:02,400 --> 00:18:05,440 Speaker 1: order to conduct these experiments, he went out to Colorado 321 00:18:05,520 --> 00:18:08,359 Speaker 1: Springs for a while and set up a laud there 322 00:18:08,560 --> 00:18:13,000 Speaker 1: and he created man made lightning to test his ideas 323 00:18:13,000 --> 00:18:15,879 Speaker 1: while he was there. The first experiment was successful in 324 00:18:15,880 --> 00:18:19,880 Speaker 1: a way, but also fairly disastrous. He did create man 325 00:18:19,880 --> 00:18:22,840 Speaker 1: made lightning, but it burned out the dynamo at the 326 00:18:22,880 --> 00:18:26,679 Speaker 1: El Paso Electric Company and the entire city lost power, 327 00:18:26,920 --> 00:18:30,440 Speaker 1: and Tesla was made to pay for the damage of 328 00:18:30,640 --> 00:18:33,560 Speaker 1: causing this outage. Yeah, the the head of the power 329 00:18:33,560 --> 00:18:35,919 Speaker 1: station wasn't very happy with him at that point. But 330 00:18:36,600 --> 00:18:39,959 Speaker 1: it was in Colorado that Tesla also noticed a signal 331 00:18:40,000 --> 00:18:42,640 Speaker 1: being picked up on his transmitter that he later said 332 00:18:42,680 --> 00:18:45,000 Speaker 1: was a signal from outer space, or he believed it 333 00:18:45,040 --> 00:18:47,960 Speaker 1: to be a signal from outer space. According to PBS 334 00:18:48,000 --> 00:18:50,800 Speaker 1: dot org, it's quite possible that he was the first 335 00:18:50,840 --> 00:18:54,679 Speaker 1: to actually detect radio signals from space. But people just 336 00:18:54,880 --> 00:18:57,800 Speaker 1: dismissed this. They just thought that he was crazy suggesting 337 00:18:57,840 --> 00:19:01,200 Speaker 1: these things. But ultimately this time in Colorado. It's it's 338 00:19:01,200 --> 00:19:03,399 Speaker 1: really interesting. It could probably be you know, a separate 339 00:19:03,400 --> 00:19:06,520 Speaker 1: episode or a blog post or something, but it's a 340 00:19:06,640 --> 00:19:09,120 Speaker 1: very shrouded in mystery. A lot of people still really 341 00:19:09,320 --> 00:19:12,639 Speaker 1: don't have a handle on exactly everything he was working 342 00:19:12,680 --> 00:19:15,399 Speaker 1: on there. It just reminds me a lot of his 343 00:19:15,600 --> 00:19:19,760 Speaker 1: role in that movie The Prestige, where um, I think 344 00:19:19,760 --> 00:19:21,320 Speaker 1: he might have been in Colorado at the time that 345 00:19:21,320 --> 00:19:23,440 Speaker 1: maybe it's been a long time since I've seen that, 346 00:19:23,520 --> 00:19:26,080 Speaker 1: but with just sort of the experiments that we're going 347 00:19:26,080 --> 00:19:29,520 Speaker 1: on there, and uh, the mystery surrounding that as well, 348 00:19:30,000 --> 00:19:32,160 Speaker 1: so we could go on and on. Like I said 349 00:19:32,160 --> 00:19:35,679 Speaker 1: about testless ideas and patents and inventions, he continued to 350 00:19:35,720 --> 00:19:38,520 Speaker 1: come up with ambitious concepts for pretty much the rest 351 00:19:38,520 --> 00:19:42,480 Speaker 1: of his life, though not much that really inspired immediate 352 00:19:42,760 --> 00:19:47,760 Speaker 1: practical applications. During his lifetime, he experimented with a new 353 00:19:47,800 --> 00:19:50,880 Speaker 1: type of turbine engine, for example, and at age seventy eight, 354 00:19:50,920 --> 00:19:53,840 Speaker 1: he announced that he was working on a death ray 355 00:19:53,960 --> 00:19:56,760 Speaker 1: that could send a concentrated beam of particles through the 356 00:19:56,760 --> 00:19:59,600 Speaker 1: air and bring down up to ten thousand enemy planes, 357 00:19:59,680 --> 00:20:03,080 Speaker 1: and this was intended by him to help prevent war, 358 00:20:03,240 --> 00:20:05,199 Speaker 1: which he really hated. I think that could be the 359 00:20:05,200 --> 00:20:07,720 Speaker 1: title of an article in his later career, to toy 360 00:20:07,800 --> 00:20:11,680 Speaker 1: Boats to Death rays Tesla's later life. So his ideas 361 00:20:11,960 --> 00:20:15,439 Speaker 1: definitely had taken on a kind of mad scientist type 362 00:20:15,600 --> 00:20:19,320 Speaker 1: edge as he aged, especially, but Tesla was really known 363 00:20:19,480 --> 00:20:22,600 Speaker 1: almost as much for his eccentricities as he was for 364 00:20:22,880 --> 00:20:25,640 Speaker 1: his inventions as the years went on, and he did 365 00:20:25,680 --> 00:20:28,200 Speaker 1: have friends. He have friends like Mark Twain, for instance, 366 00:20:28,240 --> 00:20:30,639 Speaker 1: but he never married, even though he was linked to 367 00:20:31,200 --> 00:20:34,919 Speaker 1: several heiresses at various times, and he said quote, I 368 00:20:34,960 --> 00:20:37,480 Speaker 1: did not believe an inventor should marry, because he has 369 00:20:37,560 --> 00:20:39,960 Speaker 1: so intense a nature, with so much of it of 370 00:20:40,040 --> 00:20:43,520 Speaker 1: wild passionate quality, that in giving himself to a woman 371 00:20:43,600 --> 00:20:46,520 Speaker 1: he might love, he would give everything and so take 372 00:20:46,600 --> 00:20:49,439 Speaker 1: everything from his chosen field. So he was really in 373 00:20:49,440 --> 00:20:51,600 Speaker 1: love with his work, I guess, is what he was 374 00:20:51,640 --> 00:20:54,439 Speaker 1: trying to say in part there. But according to Bailey, 375 00:20:54,520 --> 00:20:57,360 Speaker 1: he had a lot of phobias that probably prevented him 376 00:20:57,359 --> 00:20:59,879 Speaker 1: from having a relationship as well. So it wasn't just 377 00:21:00,160 --> 00:21:02,359 Speaker 1: that he wanted to give all of his intention and 378 00:21:02,400 --> 00:21:06,080 Speaker 1: focus to his work. There were some personal issues that 379 00:21:06,119 --> 00:21:08,840 Speaker 1: he had that maybe kept him from connecting with people. 380 00:21:09,320 --> 00:21:13,360 Speaker 1: For example, one of his phobias was throughout his lifetime 381 00:21:13,359 --> 00:21:15,960 Speaker 1: he sort of was a germaphobe, but he also didn't 382 00:21:15,960 --> 00:21:19,520 Speaker 1: like to touch people's hair. Specifically, he didn't like the 383 00:21:19,600 --> 00:21:23,280 Speaker 1: site of smooth round surfaces, which gave him an aversion 384 00:21:23,320 --> 00:21:28,480 Speaker 1: to women's earrings. He couldn't stand to see peaches the fruit. 385 00:21:29,080 --> 00:21:33,560 Speaker 1: He also had quote strange numerical fixation, so, for example, 386 00:21:33,600 --> 00:21:35,600 Speaker 1: the number of his hotel room always had to be 387 00:21:35,680 --> 00:21:39,280 Speaker 1: divisible by three, And strangely enough, Tesla did end up 388 00:21:39,359 --> 00:21:41,760 Speaker 1: living in a hotel, the Hotel New Yorker at the 389 00:21:41,840 --> 00:21:44,080 Speaker 1: end of his life, and he didn't have that much 390 00:21:44,119 --> 00:21:46,520 Speaker 1: money at that point, and by then some of his 391 00:21:46,640 --> 00:21:51,080 Speaker 1: closest companions where pigeons who were hanging out around the hotel. 392 00:21:51,119 --> 00:21:53,680 Speaker 1: He would actually take thick birds to his room and 393 00:21:54,160 --> 00:21:56,359 Speaker 1: nurse them back to help. He even had the hotel 394 00:21:56,440 --> 00:21:59,720 Speaker 1: make a special mixture of food for them, and he 395 00:22:00,119 --> 00:22:03,760 Speaker 1: clearly became very attached to these pets. So in one 396 00:22:03,760 --> 00:22:07,359 Speaker 1: of Tesla's favorite pigeons died, he told a newspaper writer, 397 00:22:07,480 --> 00:22:10,879 Speaker 1: John O'Neil, quote, I loved that pigeon. Yes, I loved 398 00:22:10,880 --> 00:22:13,600 Speaker 1: her as a man loved the woman. When that pigeon died, 399 00:22:13,800 --> 00:22:16,280 Speaker 1: something went out of my life. Up to that time, 400 00:22:16,320 --> 00:22:19,000 Speaker 1: I knew his certainty that I would complete my work. 401 00:22:19,320 --> 00:22:21,359 Speaker 1: But when that something went out of my life, I 402 00:22:21,480 --> 00:22:26,080 Speaker 1: knew my life's work was finished. Tesla died January seventh, 403 00:22:26,280 --> 00:22:29,360 Speaker 1: nineteen forty three. He'd gotten his last patent in nine 404 00:22:30,160 --> 00:22:32,480 Speaker 1: at the age of seventy two, and it was for 405 00:22:32,640 --> 00:22:36,199 Speaker 1: a quote apparatus for aerial transportation, which is said to 406 00:22:36,240 --> 00:22:38,840 Speaker 1: have inspired today as a vertical short take off and 407 00:22:38,920 --> 00:22:42,000 Speaker 1: landing plane, but he never had the money to actually 408 00:22:42,040 --> 00:22:45,680 Speaker 1: build a prototype of this. He never won the Nobel Prize, 409 00:22:45,720 --> 00:22:48,119 Speaker 1: though there were rumors that he and Edison might share 410 00:22:48,119 --> 00:22:51,680 Speaker 1: it in nineteen fifteen, which he was kind of unhappy about. 411 00:22:51,720 --> 00:22:53,520 Speaker 1: They didn't neither of them really wanted to share it 412 00:22:53,560 --> 00:23:00,000 Speaker 1: with each other, considering their relationship. But Tesla did ironically 413 00:23:00,160 --> 00:23:03,240 Speaker 1: win the Edison Medal in nineteen seventeen, which was the 414 00:23:03,280 --> 00:23:07,160 Speaker 1: highest honor of the American Institute of Electrical Engineers. According 415 00:23:07,160 --> 00:23:11,440 Speaker 1: to Encyclopedia Britannica. He almost didn't accept this award though, 416 00:23:11,480 --> 00:23:14,480 Speaker 1: because of the name, because of the Edison association. He 417 00:23:14,520 --> 00:23:17,399 Speaker 1: said this would basically be something that was honoring to 418 00:23:19,119 --> 00:23:22,439 Speaker 1: not honoring me. So he sat outside where the awards 419 00:23:22,480 --> 00:23:25,640 Speaker 1: ceremony was being held, feeding the pigeons for a little 420 00:23:25,640 --> 00:23:28,160 Speaker 1: while and had to be convinced to come inside, which 421 00:23:28,160 --> 00:23:31,720 Speaker 1: he finally did come inside and accept the award. Who 422 00:23:31,760 --> 00:23:34,679 Speaker 1: really won the war between Tesla and Edison? You know, 423 00:23:34,720 --> 00:23:36,879 Speaker 1: you have Tefla winning the Edison Award, but it's called 424 00:23:36,880 --> 00:23:40,040 Speaker 1: the Edison Award. I mean that really illustrates that point. 425 00:23:40,119 --> 00:23:43,159 Speaker 1: And people still debate who went out in the end. 426 00:23:43,240 --> 00:23:46,960 Speaker 1: Some say Tefla because we still use the AH system today. 427 00:23:46,960 --> 00:23:50,520 Speaker 1: I mean that system clearly one. Others, though, say Edison 428 00:23:50,560 --> 00:23:52,960 Speaker 1: because he did have more patents, he made more money, 429 00:23:53,160 --> 00:23:56,440 Speaker 1: and let's face it, he just became more famous. Tesla 430 00:23:56,560 --> 00:23:59,959 Speaker 1: has a lot of people who are clearly very devoted 431 00:24:00,000 --> 00:24:01,680 Speaker 1: to his memory. We can tell that by the number 432 00:24:01,680 --> 00:24:04,280 Speaker 1: of people who have suggested him. But I would say 433 00:24:04,280 --> 00:24:08,040 Speaker 1: Thomas Edison is probably still the more famous name. Yeah, definitely. 434 00:24:08,080 --> 00:24:12,120 Speaker 1: I think more school students learn about Edison growing up 435 00:24:12,160 --> 00:24:14,800 Speaker 1: than Tesla in their classroom, even though Tesla is the 436 00:24:14,800 --> 00:24:17,720 Speaker 1: one in our recording studio. That is true, he's on 437 00:24:17,760 --> 00:24:22,840 Speaker 1: our wall. Interesting side note here too, In just a 438 00:24:22,880 --> 00:24:26,760 Speaker 1: few months after Tesla's death, the U s. Supreme Court 439 00:24:26,920 --> 00:24:31,520 Speaker 1: upheld Tesla's radio patent over Marconi's. According to PBS dot org, 440 00:24:31,680 --> 00:24:34,399 Speaker 1: the court had a selfish reason for doing this, though. 441 00:24:34,720 --> 00:24:37,560 Speaker 1: The Marconi Company was suing the US government for use 442 00:24:37,600 --> 00:24:39,800 Speaker 1: of its patents in World War One, and so to 443 00:24:39,960 --> 00:24:42,640 Speaker 1: just kind of make that problem go away, they restored 444 00:24:42,680 --> 00:24:47,040 Speaker 1: the priority of Tesla's patent over Marconi's. So a slight 445 00:24:47,200 --> 00:24:50,200 Speaker 1: win for Tesla in the end, regardless of the reasons. 446 00:24:50,520 --> 00:24:53,879 Speaker 1: But um, still kind of a sad end to a 447 00:24:54,040 --> 00:24:59,760 Speaker 1: very interesting and inventive Yeah. So there's so much more 448 00:24:59,760 --> 00:25:01,760 Speaker 1: that we could say about Tesla, but we really did 449 00:25:01,760 --> 00:25:04,400 Speaker 1: want to focus on the current war here again. UM, 450 00:25:04,440 --> 00:25:09,199 Speaker 1: if anyone has any favorite Testlas stories or inventions or 451 00:25:09,320 --> 00:25:11,879 Speaker 1: patents that we didn't mention that you want to share 452 00:25:11,920 --> 00:25:14,280 Speaker 1: with us and and maybe the other listeners of stuff 453 00:25:14,280 --> 00:25:16,240 Speaker 1: you missed in history class, you can feel free to 454 00:25:16,960 --> 00:25:20,000 Speaker 1: write to us.
