1 00:00:00,920 --> 00:00:03,880 Speaker 1: Hello friends, It's me Josh and for this week's s 2 00:00:04,000 --> 00:00:07,560 Speaker 1: Y s K Selects, I've chosen a super cool episode 3 00:00:07,760 --> 00:00:12,600 Speaker 1: that has it all engineering, strange, physics, elon musk. What 4 00:00:12,640 --> 00:00:16,040 Speaker 1: else do you want? What more could you ask for? Also, 5 00:00:16,200 --> 00:00:19,360 Speaker 1: by the way, I'm pretty sure that the contest we 6 00:00:19,480 --> 00:00:23,560 Speaker 1: talk about in the listener mail is no longer around, 7 00:00:23,600 --> 00:00:26,800 Speaker 1: since it's many, many years old. At any rate, enjoy 8 00:00:26,880 --> 00:00:34,080 Speaker 1: this episode about the future of transportation. Welcome to Stuff 9 00:00:34,120 --> 00:00:36,680 Speaker 1: You Should Know, a production of I Heart Radios How 10 00:00:36,680 --> 00:00:45,520 Speaker 1: Stuff Works. Hey, and welcome to the podcast. I'm Josh Clark, 11 00:00:45,560 --> 00:00:51,599 Speaker 1: and there's Charles W Chuck Chuckers, Brian Yeah, and this 12 00:00:51,680 --> 00:00:57,120 Speaker 1: is Oh is that where you're going with? Sure? Yeah, 13 00:00:57,400 --> 00:00:59,720 Speaker 1: my bus right into CC writer all the style. How 14 00:00:59,760 --> 00:01:03,840 Speaker 1: would going with the Muppet Show? Oh? Yeah, it was 15 00:01:03,880 --> 00:01:07,560 Speaker 1: time we put on makeup? Yeah, what was that somebody's 16 00:01:07,600 --> 00:01:14,280 Speaker 1: giant stomach? Something like? What was that? It's weird? That 17 00:01:14,440 --> 00:01:17,880 Speaker 1: was crazy. That couldn't have been Jerry's stomach. There's no way, 18 00:01:18,400 --> 00:01:28,120 Speaker 1: all right, what's chuck? Yes? Uh, you remember our Magnet podcast. Yeah, 19 00:01:28,520 --> 00:01:32,240 Speaker 1: I've personally thought it was a great episode because we 20 00:01:32,280 --> 00:01:35,400 Speaker 1: explained how magnets work. Yeah, it was just good, tough 21 00:01:35,560 --> 00:01:38,960 Speaker 1: but good. Yeah, it was tough, but it was also 22 00:01:39,040 --> 00:01:42,360 Speaker 1: kind of um. It was one of those ones where 23 00:01:42,440 --> 00:01:45,959 Speaker 1: you're like, oh, okay, that explains pretty much everything about magnets, 24 00:01:46,040 --> 00:01:48,640 Speaker 1: the thing that I've used before in my life, and 25 00:01:48,680 --> 00:01:50,960 Speaker 1: I just kind of took for granted some people think 26 00:01:50,960 --> 00:01:54,080 Speaker 1: that they're magic, but we kind of said, this is 27 00:01:54,120 --> 00:01:57,200 Speaker 1: how they work. I liked it. So, um, I liked 28 00:01:57,800 --> 00:02:02,920 Speaker 1: this EPI, this um article in theory, the one we're 29 00:02:02,960 --> 00:02:06,400 Speaker 1: about to do a show on. Yeah, yeah, about Maglev trains. Yeah, 30 00:02:06,440 --> 00:02:10,359 Speaker 1: we did a video on Maglev trains. Remember that one 31 00:02:10,360 --> 00:02:13,440 Speaker 1: of our one of our interstitial shorts was on mag 32 00:02:13,560 --> 00:02:20,799 Speaker 1: left trains, do we Yeah, I remember doing the quantum 33 00:02:20,919 --> 00:02:25,119 Speaker 1: levitation was that it? Are you sure? Yeah? Because that's 34 00:02:25,120 --> 00:02:27,240 Speaker 1: the only way I knew about any of this was 35 00:02:27,240 --> 00:02:28,640 Speaker 1: the fact that we had talked about it before. Well 36 00:02:28,639 --> 00:02:32,600 Speaker 1: what did we talk about, uh, maglob you know the 37 00:02:32,600 --> 00:02:36,000 Speaker 1: basic principle in one minute behind magnetic levitation. Well, that's 38 00:02:36,000 --> 00:02:39,480 Speaker 1: pretty much what we're gonna do here, Yeah, except slightly longer. Yeah. 39 00:02:39,560 --> 00:02:43,639 Speaker 1: So um that was my intro but intro and we 40 00:02:43,680 --> 00:02:48,799 Speaker 1: should say also, um, everyone, it is next to impossible 41 00:02:49,080 --> 00:02:52,240 Speaker 1: to get up to the minute up to the year 42 00:02:52,520 --> 00:02:58,480 Speaker 1: information about what maglev trains are in operation, what are 43 00:02:58,520 --> 00:03:01,840 Speaker 1: still planned, what's still going on. So it is possible 44 00:03:02,160 --> 00:03:06,119 Speaker 1: we may get that part a little incorrect, but we're 45 00:03:06,240 --> 00:03:09,399 Speaker 1: going to try our best to be as accurate as possible. Yeah, 46 00:03:09,639 --> 00:03:13,120 Speaker 1: and the reason why is because magnetic levitation to power 47 00:03:13,160 --> 00:03:16,760 Speaker 1: a train so new. Well, it's actually not that new, 48 00:03:16,760 --> 00:03:18,320 Speaker 1: because they've been doing it for a while and well 49 00:03:18,919 --> 00:03:21,840 Speaker 1: start it was proposed ever since Tesla started noticing what 50 00:03:21,919 --> 00:03:24,560 Speaker 1: was going on in the late nineteenth century. But it's 51 00:03:24,600 --> 00:03:28,880 Speaker 1: so new in this regard as far as super fast 52 00:03:29,240 --> 00:03:35,800 Speaker 1: speed trains powered by magnets transporting lots of people over distances, 53 00:03:35,800 --> 00:03:38,920 Speaker 1: maybe great distances. That is so new, and there's so 54 00:03:39,160 --> 00:03:41,720 Speaker 1: a few different technologies that it is kind of hard 55 00:03:41,720 --> 00:03:43,600 Speaker 1: to keep track on which one is in the forefront, 56 00:03:44,160 --> 00:03:48,080 Speaker 1: which ones are being funded because the stuff is expensive, 57 00:03:48,600 --> 00:03:50,840 Speaker 1: it is it's hard to get funding, especially here in 58 00:03:50,840 --> 00:03:52,840 Speaker 1: the States. Yeah, and if you go on, if you 59 00:03:52,920 --> 00:03:55,720 Speaker 1: just type mag LEVI into Google or your favorite search 60 00:03:55,720 --> 00:03:59,080 Speaker 1: engine UM or Duck duck go, if you're you know, 61 00:04:00,080 --> 00:04:02,560 Speaker 1: kind of watching who's watching you? Oh, is that a 62 00:04:02,720 --> 00:04:07,160 Speaker 1: like a secret? It's like an anonymous search engine okay. Um, 63 00:04:07,400 --> 00:04:11,120 Speaker 1: you will find there's projects all over the United States 64 00:04:11,280 --> 00:04:13,040 Speaker 1: and all of them are like, we're shove already, We're 65 00:04:13,040 --> 00:04:15,480 Speaker 1: ready to go. Just give us some money. And they're 66 00:04:15,520 --> 00:04:18,320 Speaker 1: not getting any money because the construction costs are so 67 00:04:18,560 --> 00:04:23,000 Speaker 1: enormous because with maglev trains you can't use existing railways. 68 00:04:23,560 --> 00:04:26,479 Speaker 1: It's all new. And uh, I saw one quote and 69 00:04:26,800 --> 00:04:30,080 Speaker 1: again who knows how recent this is, but fifty million 70 00:04:30,120 --> 00:04:32,880 Speaker 1: euros per mile. I can believe this is what the 71 00:04:32,920 --> 00:04:37,479 Speaker 1: German Consortium is quoting. The thing is is, once you 72 00:04:37,520 --> 00:04:41,520 Speaker 1: get it built, maintenance is not bad. Yeah, not bad 73 00:04:41,520 --> 00:04:43,039 Speaker 1: at all, because there's not a lot of wear and 74 00:04:43,080 --> 00:04:45,800 Speaker 1: tear on it. As you'll see no friction baby. Um. 75 00:04:45,839 --> 00:04:48,400 Speaker 1: And if you do look into maglev, you will see 76 00:04:48,400 --> 00:04:52,440 Speaker 1: that it is very much like the the transportation technology 77 00:04:52,480 --> 00:04:56,440 Speaker 1: of the future that's going on today. Um, especially after 78 00:04:56,600 --> 00:05:02,080 Speaker 1: looking into Elon Musk's um T hyper loop thing. I 79 00:05:02,320 --> 00:05:05,640 Speaker 1: heard of that. So basically Elon Musk, who is like 80 00:05:05,680 --> 00:05:09,679 Speaker 1: our good friend, uh, super rich guy, right, he basically 81 00:05:09,720 --> 00:05:12,040 Speaker 1: just jotted down this idea on a cocktail napkin and 82 00:05:12,080 --> 00:05:14,799 Speaker 1: all of a sudden it's like the new thing. But um, 83 00:05:14,839 --> 00:05:19,680 Speaker 1: it's a an enclosed tube system that just you put 84 00:05:19,720 --> 00:05:23,240 Speaker 1: in a little car or whatever that seats twelve people 85 00:05:23,360 --> 00:05:26,599 Speaker 1: or something comfortably and you suck all the air out 86 00:05:26,600 --> 00:05:31,719 Speaker 1: of it no resistance, so you can go really fast. Basically, 87 00:05:31,760 --> 00:05:34,400 Speaker 1: I think it goes about seven a little under the 88 00:05:34,440 --> 00:05:37,440 Speaker 1: speed of sound, so you can get from the west 89 00:05:37,480 --> 00:05:40,720 Speaker 1: coast to the east coast or vice versa very very fast. 90 00:05:41,200 --> 00:05:46,760 Speaker 1: The thing is, the construction costs for this or just preposterous. 91 00:05:46,800 --> 00:05:50,840 Speaker 1: But if it can come along or come down a 92 00:05:50,880 --> 00:05:53,919 Speaker 1: little more, then it will give Maglev a run for 93 00:05:53,960 --> 00:05:57,760 Speaker 1: its money. But if it, if Maglev can start to 94 00:05:57,880 --> 00:06:00,719 Speaker 1: really kind of get some traction and get some line going, 95 00:06:01,520 --> 00:06:04,200 Speaker 1: it will be the the movement of the future for 96 00:06:04,200 --> 00:06:07,320 Speaker 1: at least a decade or two. Yeah, I saw where 97 00:06:08,360 --> 00:06:12,200 Speaker 1: they're proposing both in the future Maglev trains that operate 98 00:06:12,240 --> 00:06:16,640 Speaker 1: inside vacuum tubes as fast as two thousand miles an 99 00:06:16,640 --> 00:06:20,040 Speaker 1: hour as crazy. Right now they're breaking records like three 100 00:06:20,440 --> 00:06:23,359 Speaker 1: miles an hour plus what's the fastest right now? The 101 00:06:24,640 --> 00:06:27,839 Speaker 1: So apparently this is kind of mind boggling because Maglev 102 00:06:28,279 --> 00:06:31,440 Speaker 1: as again we realize everybody, we haven't explained what Maglev 103 00:06:31,520 --> 00:06:37,680 Speaker 1: is talking here, but um, Maglev, the the great advantage 104 00:06:37,680 --> 00:06:41,000 Speaker 1: it has is that it's supposedly goes faster than the 105 00:06:41,080 --> 00:06:45,520 Speaker 1: normal steel wheel train. Apparently a TGV train, which is 106 00:06:45,520 --> 00:06:50,560 Speaker 1: a steel wheel train. UM in Europe, they they beat 107 00:06:50,760 --> 00:06:53,280 Speaker 1: a maglev land speed really that was held by the 108 00:06:53,400 --> 00:06:57,360 Speaker 1: Japanese Maglev of about three hundred and fifty one miles 109 00:06:57,400 --> 00:06:59,600 Speaker 1: an hour. I think it went like three sixty. Man. 110 00:06:59,640 --> 00:07:02,880 Speaker 1: I don't if i'd feel safe. Yeah, I can imagine. 111 00:07:03,040 --> 00:07:05,000 Speaker 1: I was. I was reading a quote from a Maglev 112 00:07:05,160 --> 00:07:08,520 Speaker 1: rider and they were saying, like, you can tell you're 113 00:07:08,520 --> 00:07:12,720 Speaker 1: going really fast, like on the bullet train. He was 114 00:07:12,760 --> 00:07:14,800 Speaker 1: gonna be so disappointed because she's taught me how to 115 00:07:14,840 --> 00:07:17,120 Speaker 1: say it in Japanese so many times a night. I 116 00:07:17,160 --> 00:07:20,320 Speaker 1: don't want to BUTCHERP. But the bullet train it goes 117 00:07:20,360 --> 00:07:23,400 Speaker 1: pretty fast, like hundred fifty miles an hour or something, 118 00:07:23,880 --> 00:07:27,120 Speaker 1: but it just looks like everything's a blur. You don't 119 00:07:27,160 --> 00:07:29,920 Speaker 1: feel like you're going fast. Apparently in a maglev it 120 00:07:29,960 --> 00:07:32,600 Speaker 1: goes fast enough to wear like you feel like, holy cow, 121 00:07:32,840 --> 00:07:35,280 Speaker 1: we're going three d and fifty miles an hour. Well, 122 00:07:35,280 --> 00:07:38,960 Speaker 1: our very unparent company did a show World's Fastest Trains, 123 00:07:39,600 --> 00:07:42,920 Speaker 1: and I watched the maglev segment in the dude. You know. 124 00:07:42,920 --> 00:07:44,560 Speaker 1: I was in the front room with the driver and 125 00:07:44,600 --> 00:07:46,240 Speaker 1: they were like, all right, we're going three hundred miles 126 00:07:46,240 --> 00:07:49,200 Speaker 1: an hour now, and it's hard to tell on the TV. 127 00:07:49,400 --> 00:07:52,360 Speaker 1: You know exactly how fast you're going, because I looked 128 00:07:52,360 --> 00:07:54,000 Speaker 1: and I was like, well, then you know, it looks 129 00:07:54,000 --> 00:07:56,680 Speaker 1: like about a hundred to me. But um, yeah, I 130 00:07:56,720 --> 00:07:58,640 Speaker 1: think being on the train and I think the key 131 00:07:58,680 --> 00:08:01,360 Speaker 1: to not feeling two or it is obviously you're not 132 00:08:01,440 --> 00:08:03,560 Speaker 1: being shot out like a bullet. You're you're ramping up 133 00:08:03,560 --> 00:08:06,000 Speaker 1: to that speed, so that helps. Plus if you dressed 134 00:08:06,000 --> 00:08:08,400 Speaker 1: normally for your train ride, you'll feel less weird too, 135 00:08:08,880 --> 00:08:12,440 Speaker 1: that's right. Um. Also, hold on one more thing, um 136 00:08:12,520 --> 00:08:19,840 Speaker 1: that we're talking very high speeds. That's the that's the 137 00:08:19,880 --> 00:08:23,440 Speaker 1: speed record of a maglev. But they're averaging like to 138 00:08:23,680 --> 00:08:27,440 Speaker 1: fifty or more, which means if you, if you get 139 00:08:27,440 --> 00:08:30,080 Speaker 1: these things built, you're going to expand the range of 140 00:08:30,120 --> 00:08:32,440 Speaker 1: where people can live and commute and go to work 141 00:08:32,440 --> 00:08:36,960 Speaker 1: every day tremendously. Um. So there's a lot of value 142 00:08:36,960 --> 00:08:41,520 Speaker 1: in creating these mag levs. Right are we there yet? Well, 143 00:08:41,559 --> 00:08:44,040 Speaker 1: before we do that, let's just might as well do 144 00:08:44,080 --> 00:08:46,000 Speaker 1: a message break now, huh. I think it's a good time, 145 00:09:01,400 --> 00:09:04,560 Speaker 1: all right, So now can we get down to brass tacks. Yes, 146 00:09:05,440 --> 00:09:09,840 Speaker 1: let's okay. Um, this is kind of confusing because I 147 00:09:09,880 --> 00:09:14,000 Speaker 1: read a paper in night, I think, where this guy 148 00:09:14,120 --> 00:09:15,960 Speaker 1: was saying, like, there's a lot of people calling all 149 00:09:15,960 --> 00:09:21,000 Speaker 1: these different technologies maglev. This is all very early stage 150 00:09:21,080 --> 00:09:24,480 Speaker 1: proposal hadn't been proven yet, but he was saying, there's 151 00:09:24,520 --> 00:09:27,320 Speaker 1: at least seven different kinds of technology here that everyone's 152 00:09:27,360 --> 00:09:29,960 Speaker 1: calling maglev that are different enough that it doesn't They're 153 00:09:30,000 --> 00:09:33,839 Speaker 1: just different. But for the purposes of this podcast, we 154 00:09:33,880 --> 00:09:36,520 Speaker 1: can get it with maglev, but we have to point 155 00:09:36,520 --> 00:09:39,880 Speaker 1: out that there are some really different systems that are 156 00:09:39,960 --> 00:09:43,240 Speaker 1: in use in being proposed right now, and a lot 157 00:09:43,280 --> 00:09:47,040 Speaker 1: of them have to do with the suspension systems. Yeah, 158 00:09:47,120 --> 00:09:51,680 Speaker 1: I think what's going on now? There are three pretty 159 00:09:51,760 --> 00:09:56,079 Speaker 1: much leading competing systems, right. Yeah, because we should say, chuck. 160 00:09:56,280 --> 00:09:59,400 Speaker 1: A maglev train is a train that uses magnets to 161 00:09:59,440 --> 00:10:05,000 Speaker 1: float above a track by either a half a centimeter too. 162 00:10:05,040 --> 00:10:07,200 Speaker 1: I saw one that floats up to a foot off 163 00:10:07,200 --> 00:10:09,199 Speaker 1: the track, and that's a little scary. It seems a 164 00:10:09,240 --> 00:10:12,160 Speaker 1: little scary, but apparently the higher you go, and that 165 00:10:12,400 --> 00:10:16,560 Speaker 1: that high end of the range, the more stable it is. Alright, yeah, 166 00:10:16,600 --> 00:10:19,679 Speaker 1: but so the the train is literally not touching the 167 00:10:19,679 --> 00:10:23,080 Speaker 1: tracks and it floats along. And the reason that's why 168 00:10:23,120 --> 00:10:25,559 Speaker 1: it can go so fast is because there's no friction, 169 00:10:26,120 --> 00:10:29,160 Speaker 1: no friction, The only resistance is air. And they're super 170 00:10:29,160 --> 00:10:32,600 Speaker 1: sleek of course, so even the error is cut down. Uh. 171 00:10:32,640 --> 00:10:35,719 Speaker 1: So let's go. Let's go to Germany first, because they 172 00:10:35,760 --> 00:10:40,319 Speaker 1: have a system, uh, trans Rapid. It's called the actually 173 00:10:40,360 --> 00:10:43,360 Speaker 1: company is called trans Rapid International. There's also a trans 174 00:10:43,440 --> 00:10:47,920 Speaker 1: Rapid USA. Now I think USA, that's right. Uh. And 175 00:10:48,000 --> 00:10:53,160 Speaker 1: the German version is electro magnetic suspension. And the way 176 00:10:53,200 --> 00:10:56,520 Speaker 1: that the guy on the Discovery Channel show described it 177 00:10:56,640 --> 00:11:00,800 Speaker 1: was that electro magnets, Well, when you use electro magnets, 178 00:11:00,920 --> 00:11:05,360 Speaker 1: they're only um magnetize when there's a power source, when 179 00:11:05,360 --> 00:11:09,160 Speaker 1: there's electricity running through exactly. So that's important to remember 180 00:11:09,360 --> 00:11:11,880 Speaker 1: it is and we'll point out why later because in 181 00:11:11,920 --> 00:11:15,439 Speaker 1: the German system, uh, the e m S system, it's 182 00:11:15,520 --> 00:11:19,720 Speaker 1: all about attraction. It's not repelled magnets repelling each other. 183 00:11:20,280 --> 00:11:23,000 Speaker 1: It's magnets that are attracted to each other. And the 184 00:11:23,040 --> 00:11:27,360 Speaker 1: reason that they float is they're basically switching it on 185 00:11:27,440 --> 00:11:31,840 Speaker 1: and off, pulsing the electromatic magnets so fast that it 186 00:11:31,880 --> 00:11:37,600 Speaker 1: creates that hovering attraction. Okay, so that's the German version, 187 00:11:38,080 --> 00:11:42,760 Speaker 1: so um okay. And apparently this German version, I think 188 00:11:42,760 --> 00:11:45,200 Speaker 1: they do use repulsive magnets, but on the sides for 189 00:11:45,240 --> 00:11:50,440 Speaker 1: the guidance magnets. So to make it hover, they're turning 190 00:11:50,440 --> 00:11:52,439 Speaker 1: it on an awful lot. So it wants to stick 191 00:11:52,480 --> 00:11:54,679 Speaker 1: but no, but stick but no. And there's not a 192 00:11:54,760 --> 00:11:56,880 Speaker 1: dude on a switch doing it really fast. It's all 193 00:11:56,920 --> 00:12:00,760 Speaker 1: programmed to pull. Right. They have computers handling um. And 194 00:12:00,760 --> 00:12:04,160 Speaker 1: then so this is the the suspension system you're talking about, right, 195 00:12:04,160 --> 00:12:08,920 Speaker 1: the electro magnetic suspension. And the word suspension is kind 196 00:12:08,920 --> 00:12:11,440 Speaker 1: of easily overlooked, but in this case we're literally talking 197 00:12:11,480 --> 00:12:15,800 Speaker 1: about how the train is suspended in mid air above 198 00:12:15,960 --> 00:12:19,520 Speaker 1: the track in this case, and with the e M 199 00:12:19,600 --> 00:12:23,120 Speaker 1: S it's about I think, uh, half a centimeter to 200 00:12:23,200 --> 00:12:26,160 Speaker 1: a centimeter. It's it's very close to the to the track, 201 00:12:26,840 --> 00:12:30,600 Speaker 1: and they use the electro magnets to attract and they 202 00:12:30,720 --> 00:12:33,400 Speaker 1: use the guidance magnets, which are magnets installed on the 203 00:12:33,480 --> 00:12:37,920 Speaker 1: side of the train, uh that are along the side 204 00:12:37,920 --> 00:12:41,120 Speaker 1: of the track to repel magnets along the side of 205 00:12:41,120 --> 00:12:44,960 Speaker 1: the track to keep the train from bumping into the 206 00:12:45,000 --> 00:12:50,040 Speaker 1: guide rails. But the it requires a um UH computer 207 00:12:50,120 --> 00:12:54,160 Speaker 1: system that constantly make adjustments to the current that's going 208 00:12:54,200 --> 00:12:59,120 Speaker 1: through these electro magnets to either um to either attract 209 00:12:59,160 --> 00:13:01,760 Speaker 1: the train to make it float or to repel it 210 00:13:01,840 --> 00:13:03,920 Speaker 1: from the sides to adjust it to make sure it 211 00:13:03,960 --> 00:13:06,560 Speaker 1: never bumps into the rails or the track, because if 212 00:13:06,559 --> 00:13:11,520 Speaker 1: you're going fifty miles an hour and your train scuffs 213 00:13:11,600 --> 00:13:14,480 Speaker 1: the track, you're in big trouble or big trouble. One 214 00:13:14,480 --> 00:13:18,240 Speaker 1: advantage of this UH the German system is that you 215 00:13:18,320 --> 00:13:20,480 Speaker 1: only need the power on for the section of track 216 00:13:20,559 --> 00:13:25,200 Speaker 1: that you're using at the time, So they literally will 217 00:13:25,240 --> 00:13:28,599 Speaker 1: turn on a section of track, the train goes over it, 218 00:13:28,640 --> 00:13:30,559 Speaker 1: and then they'll turn it back off. Right, So it's 219 00:13:30,640 --> 00:13:34,440 Speaker 1: very like economically fuel will not fuel efficient because it's 220 00:13:34,480 --> 00:13:37,360 Speaker 1: not fuel right, and that's the power efficient right. And 221 00:13:37,400 --> 00:13:40,360 Speaker 1: it doesn't use fossil fuels in the sense that a 222 00:13:40,360 --> 00:13:42,960 Speaker 1: normal train does, although if you go far enough down 223 00:13:42,960 --> 00:13:45,599 Speaker 1: the line, that electricity has to come from somewhere, so 224 00:13:45,679 --> 00:13:49,440 Speaker 1: ultimately it is coming from fossil fuels. But the efficiency. 225 00:13:49,720 --> 00:13:54,040 Speaker 1: Fuel efficiency is incredible compared to you know, a normal 226 00:13:54,640 --> 00:13:58,240 Speaker 1: train that burns cossal fuels just to move right, the 227 00:13:58,320 --> 00:14:02,000 Speaker 1: guy's shoveling coal into a fire. Yeah, I should say so. 228 00:14:02,400 --> 00:14:08,120 Speaker 1: My understanding of the delivery of electricity to the track 229 00:14:08,240 --> 00:14:11,600 Speaker 1: is the same for both suspension systems that you propel 230 00:14:11,760 --> 00:14:16,160 Speaker 1: like that. So the whole track is made of electro magnets, right, 231 00:14:17,840 --> 00:14:21,880 Speaker 1: come on both systems, and you're just sending electricity to 232 00:14:21,960 --> 00:14:25,400 Speaker 1: the electromagnets that are immediately in front of and immediately 233 00:14:25,480 --> 00:14:30,280 Speaker 1: behind the train immediately under. Yeah, because you need it. 234 00:14:30,280 --> 00:14:31,680 Speaker 1: You need to float the train, then you need to 235 00:14:31,680 --> 00:14:33,840 Speaker 1: propel it, right, And the way you're propelling it is 236 00:14:33,880 --> 00:14:36,720 Speaker 1: the magnets that are just ahead of the train are 237 00:14:36,880 --> 00:14:40,400 Speaker 1: going to be positive, and so that's going to attract 238 00:14:40,440 --> 00:14:43,280 Speaker 1: the train, meaning it's gonna pull it forward. And then 239 00:14:43,320 --> 00:14:46,000 Speaker 1: the the magnets behind it are going to be charged 240 00:14:46,040 --> 00:14:49,560 Speaker 1: so that they're negative and they're going to repel the 241 00:14:49,600 --> 00:14:52,760 Speaker 1: train push it. So in the front, the magnets are 242 00:14:52,760 --> 00:14:55,240 Speaker 1: pulling it in the in the back, the magnets are 243 00:14:55,240 --> 00:14:58,880 Speaker 1: pushing it. And again remember there's no friction here, it's 244 00:14:58,960 --> 00:15:01,840 Speaker 1: just air, so it doesn't take a whole lot to 245 00:15:02,160 --> 00:15:05,920 Speaker 1: make this train go really really fast, just using magnets. Yeah, 246 00:15:05,960 --> 00:15:10,600 Speaker 1: and they in two thousand two debuted commercially in Shanghai, China, 247 00:15:11,280 --> 00:15:16,240 Speaker 1: a pretty short run transporting people um from airport to airport, 248 00:15:16,320 --> 00:15:20,240 Speaker 1: basically um at a speed it speeds over two fifty 249 00:15:20,240 --> 00:15:22,920 Speaker 1: miles an hour. So I read that the journey the 250 00:15:23,000 --> 00:15:24,720 Speaker 1: nineteen mile journey. Now it takes about seven and a 251 00:15:24,800 --> 00:15:27,440 Speaker 1: half minutes as opposed to about an hour in a cab, 252 00:15:28,360 --> 00:15:32,160 Speaker 1: and they were going to expand it, but that was 253 00:15:32,240 --> 00:15:37,000 Speaker 1: halted in two thousand eight over radiation fears by people. 254 00:15:37,760 --> 00:15:42,280 Speaker 1: And now it's being proposed as an underground system, like 255 00:15:42,360 --> 00:15:45,240 Speaker 1: to go underground to halt those fears. But in two 256 00:15:45,240 --> 00:15:48,600 Speaker 1: thousand ten, another high speed train in the area was 257 00:15:49,280 --> 00:15:52,440 Speaker 1: a non maglev system opened, so they basically said, well, 258 00:15:52,480 --> 00:15:55,000 Speaker 1: we probably won't do this. Uh, we probably won't extend 259 00:15:55,000 --> 00:15:57,440 Speaker 1: the Shanghai line now, So yeah, I heard it's definitely 260 00:15:57,440 --> 00:16:00,080 Speaker 1: on hold, but I didn't hear that they decide that 261 00:16:00,160 --> 00:16:04,320 Speaker 1: they weren't going to do it. Well, the regular bullet 262 00:16:04,360 --> 00:16:07,280 Speaker 1: train popped up and they're like, well, now that we 263 00:16:07,320 --> 00:16:10,480 Speaker 1: have that, I guess we don't need the mag left. Well, oh, well, 264 00:16:10,840 --> 00:16:16,160 Speaker 1: so Japan's got the other, um big rival system. Uh 265 00:16:16,360 --> 00:16:18,920 Speaker 1: so the propulsion systems are the same. You use magnets 266 00:16:18,960 --> 00:16:21,080 Speaker 1: ahead of the train and behind the train to attract 267 00:16:21,120 --> 00:16:23,520 Speaker 1: or repell it right to push it forward, I believe 268 00:16:23,560 --> 00:16:27,280 Speaker 1: so so um, the suspension systems are what differ. In 269 00:16:27,320 --> 00:16:31,720 Speaker 1: Germany you're using magnets to um repel it, right, to 270 00:16:31,760 --> 00:16:35,080 Speaker 1: attract it, to attract it. In Japan you're using something 271 00:16:35,120 --> 00:16:38,400 Speaker 1: called the Meisner effect. So basically, chuck. The Meisner effect 272 00:16:38,520 --> 00:16:43,880 Speaker 1: is where you take a super cooled superconductor, right, yes, 273 00:16:44,160 --> 00:16:47,920 Speaker 1: I think like liquid helium temperature, which is very very cold, 274 00:16:48,800 --> 00:16:51,720 Speaker 1: and you put it in a magnetic field. The magnetic 275 00:16:51,800 --> 00:16:55,800 Speaker 1: field basically hugs it. It goes around it rather than 276 00:16:55,840 --> 00:17:00,240 Speaker 1: through it. Okay, yes, um, so when you do at 277 00:17:01,280 --> 00:17:05,920 Speaker 1: the field actually levitates the thing. So if you take 278 00:17:06,080 --> 00:17:09,960 Speaker 1: enough superconductors that are at the right temperature and you 279 00:17:10,040 --> 00:17:13,920 Speaker 1: put them in the presence of a magnetic field, a 280 00:17:13,960 --> 00:17:18,639 Speaker 1: whole bunch of magnets, say on a train, the the 281 00:17:18,720 --> 00:17:24,679 Speaker 1: magnet will float, it will levitate, and that's the electrodynamic 282 00:17:24,760 --> 00:17:28,399 Speaker 1: suspension that the Japanese are using. So basically you have 283 00:17:28,560 --> 00:17:32,160 Speaker 1: a tunnel, a magnetic field tunnel that these things are 284 00:17:32,200 --> 00:17:35,840 Speaker 1: traveling through, which means that there they don't they don't 285 00:17:35,840 --> 00:17:38,360 Speaker 1: need any extra magnets on the sides, or they don't 286 00:17:38,359 --> 00:17:40,959 Speaker 1: need any on the bottom or extra magnets on the bottom. 287 00:17:41,119 --> 00:17:45,400 Speaker 1: It's just going to stay put within this bent magnetic 288 00:17:45,440 --> 00:17:48,959 Speaker 1: field that's warped to wrap around it. It's never going 289 00:17:49,000 --> 00:17:52,600 Speaker 1: to drop, and it's totally stable, which is the big 290 00:17:52,680 --> 00:17:55,240 Speaker 1: that's a big advantage from what I understand of the 291 00:17:55,320 --> 00:17:59,400 Speaker 1: Japanese system over the German system. The stability doesn't require 292 00:17:59,440 --> 00:18:02,760 Speaker 1: a bunch of pewters to constantly adjust it, and it 293 00:18:02,920 --> 00:18:06,480 Speaker 1: is just inherently more stable because it's not just being 294 00:18:06,520 --> 00:18:08,480 Speaker 1: held up from the bottom and then a little on 295 00:18:08,520 --> 00:18:12,560 Speaker 1: the sides. It is wrapped in this basically blanket of 296 00:18:12,600 --> 00:18:19,400 Speaker 1: an electromagnetic field. Uh. It can conduct power electricity even 297 00:18:19,440 --> 00:18:21,720 Speaker 1: when the power is cut off, so that's a definite advantage. 298 00:18:22,240 --> 00:18:24,720 Speaker 1: Um Although the German system does have like battery backups, 299 00:18:24,720 --> 00:18:26,680 Speaker 1: it's not like if the power went off, the train 300 00:18:26,720 --> 00:18:31,160 Speaker 1: would just go and stop. But the German one doesn't 301 00:18:31,160 --> 00:18:34,359 Speaker 1: never doesn't need tires, and the Japanese one does, yeah, 302 00:18:34,400 --> 00:18:36,520 Speaker 1: because it needs to ramp up to a certain speed 303 00:18:36,600 --> 00:18:39,879 Speaker 1: in order to begin the float. It doesn't just start immediately. 304 00:18:40,040 --> 00:18:42,560 Speaker 1: What is it like eighty eight miles that's back to 305 00:18:42,600 --> 00:18:47,119 Speaker 1: the future sixty two. And I think they use liquid 306 00:18:47,200 --> 00:18:52,320 Speaker 1: nitrogen and it's just expensive to super cool these UH coils, 307 00:18:52,680 --> 00:18:55,120 Speaker 1: and I think that's one of the drawbicks. But they're 308 00:18:55,160 --> 00:18:59,000 Speaker 1: all expensive. They're none of this is they haven't figured 309 00:18:59,040 --> 00:19:01,639 Speaker 1: out a cheap way to do any of this. Now, 310 00:19:01,720 --> 00:19:05,960 Speaker 1: there's a proposed line um in Japan. It's already it's 311 00:19:06,000 --> 00:19:09,520 Speaker 1: the one that set the UH that land speed record 312 00:19:09,600 --> 00:19:15,120 Speaker 1: for maglev trains. It's the j R tok Um that's 313 00:19:15,160 --> 00:19:19,320 Speaker 1: the railway company to kind of close, but it's their 314 00:19:19,400 --> 00:19:23,400 Speaker 1: line um supposedly, supposedly is already in operation. I read 315 00:19:23,400 --> 00:19:26,359 Speaker 1: somewhere that it's moved like a million people already. But 316 00:19:26,440 --> 00:19:28,720 Speaker 1: they have a proposed line that they want to open 317 00:19:28,720 --> 00:19:33,360 Speaker 1: by seven and it's from Tokyo to Nagoya, and then 318 00:19:33,359 --> 00:19:36,760 Speaker 1: they want to extend that from Tokyo to Osaka by 319 00:19:38,600 --> 00:19:42,400 Speaker 1: and they're talking like it's like a fifty billion dollar project, 320 00:19:42,440 --> 00:19:45,840 Speaker 1: and I think that's just the first line that's Yeah, 321 00:19:45,880 --> 00:19:48,080 Speaker 1: it sounds about right. But the reason that it probably 322 00:19:48,119 --> 00:19:51,600 Speaker 1: will happen is they're they're um basing all of this 323 00:19:51,720 --> 00:19:55,560 Speaker 1: on data showing that people are going to keep moving 324 00:19:55,560 --> 00:19:58,080 Speaker 1: to Japan and Osaka, so they're going to have customers 325 00:19:58,440 --> 00:20:01,000 Speaker 1: and they're not relying on any money. They have so 326 00:20:01,080 --> 00:20:03,320 Speaker 1: much money they're just going to fund it themselves. Is 327 00:20:03,560 --> 00:20:06,920 Speaker 1: privately funded. Yeah. Yeah. Another con though of the Japanese 328 00:20:07,000 --> 00:20:09,200 Speaker 1: version is that if you have a pacemaker, you don't 329 00:20:09,200 --> 00:20:12,800 Speaker 1: want to get on that train because, um, that magnetic 330 00:20:12,840 --> 00:20:17,480 Speaker 1: field will reek havoc and you probably won't live. It 331 00:20:17,520 --> 00:20:19,960 Speaker 1: will shut you down. It will shut you down. And 332 00:20:20,000 --> 00:20:23,879 Speaker 1: then there's the in duct track and that is another 333 00:20:23,960 --> 00:20:27,080 Speaker 1: type of E d S system, which is the Japanese system, 334 00:20:27,400 --> 00:20:31,159 Speaker 1: except that they use room temperature magnets. And from what 335 00:20:31,240 --> 00:20:36,040 Speaker 1: I could tell, this is as close to just the 336 00:20:36,440 --> 00:20:41,400 Speaker 1: whole thing of two magnets, regular magnets opposing each other 337 00:20:41,920 --> 00:20:44,800 Speaker 1: and they're just gonna use that, right, Yeah, Like it's 338 00:20:44,840 --> 00:20:46,560 Speaker 1: as close to we get as you going out to 339 00:20:46,560 --> 00:20:49,560 Speaker 1: the store and getting two magnets and putting their like 340 00:20:49,720 --> 00:20:53,280 Speaker 1: poles against each other so that they repel. Yeah. There's 341 00:20:53,280 --> 00:20:55,960 Speaker 1: actually something called the hull Bock array, which is a 342 00:20:56,000 --> 00:20:58,800 Speaker 1: way to just line up the magnets um in certain 343 00:20:58,840 --> 00:21:03,119 Speaker 1: directions so that they're holes are facing north, southeast or west. UM. 344 00:21:03,200 --> 00:21:06,560 Speaker 1: And when you put them together in a clump, basically, 345 00:21:06,640 --> 00:21:13,520 Speaker 1: the the magnetic field below the magnets doubles, the magnetic 346 00:21:13,520 --> 00:21:16,200 Speaker 1: field on the top of the magnet cancels one another 347 00:21:16,280 --> 00:21:19,960 Speaker 1: out right, So you have your extra strong magnetic magnetic 348 00:21:20,000 --> 00:21:24,359 Speaker 1: field that can produce this Meisner effect basically UM without 349 00:21:24,400 --> 00:21:28,600 Speaker 1: this super cooled superconductor. Yeah. And these aren't even electro magnets. 350 00:21:28,600 --> 00:21:30,400 Speaker 1: I don't think. Aren't they just magnets. I think they're 351 00:21:30,440 --> 00:21:34,120 Speaker 1: permanent room temperature magnets. It's crazy. Yeah, there are three 352 00:21:34,400 --> 00:21:37,960 Speaker 1: UM designs right now the in duct track one, two, 353 00:21:37,960 --> 00:21:42,639 Speaker 1: and three. UM One is high speed, two is slow speed, 354 00:21:43,040 --> 00:21:46,760 Speaker 1: and three is heavy load slow speed. Yeah, so I 355 00:21:46,800 --> 00:21:49,840 Speaker 1: guess just freighting stuff back and forth. You know they 356 00:21:49,840 --> 00:21:51,720 Speaker 1: did this in London at one point, but then shut 357 00:21:51,760 --> 00:21:55,040 Speaker 1: it down. Like in the eighties they had a maglife train. Yeah, 358 00:21:55,119 --> 00:21:57,639 Speaker 1: just a very slow moving like it might have been 359 00:21:57,680 --> 00:22:00,640 Speaker 1: an airport type situation. And I looked up the one 360 00:22:00,640 --> 00:22:04,040 Speaker 1: here in Atlanta, the new airport trainer. I thought it 361 00:22:04,119 --> 00:22:05,960 Speaker 1: might have been maglev, but of course it's not. It's 362 00:22:05,960 --> 00:22:10,920 Speaker 1: just wheels, just stupid wheels. UM although they held Atlanta 363 00:22:10,960 --> 00:22:13,600 Speaker 1: have its day. Well, they have proposed one Atlanta is 364 00:22:13,600 --> 00:22:16,440 Speaker 1: one of the city's um that's trying to get maglev 365 00:22:16,520 --> 00:22:20,640 Speaker 1: going between Atlanta and Chattanooga. And there's one proposed between 366 00:22:20,800 --> 00:22:23,960 Speaker 1: d C and Baltimore. One in Las Vegas, Yeah, La 367 00:22:24,000 --> 00:22:28,960 Speaker 1: in Vegas. Um. And I think one from Pittsburgh to someplace, 368 00:22:30,119 --> 00:22:33,080 Speaker 1: but I'm not sure exactly where I saw that one too. 369 00:22:33,119 --> 00:22:37,119 Speaker 1: I don't remember where it might have been, d C, Dtsburg, Philly. Yeah. Well, 370 00:22:37,160 --> 00:22:39,520 Speaker 1: hold on, we're getting ahead of ourselves. Man. Well, no, 371 00:22:39,640 --> 00:22:41,800 Speaker 1: these are just proposals, and and they're having a hard 372 00:22:41,800 --> 00:22:44,280 Speaker 1: time getting the funding they need for any of these 373 00:22:44,359 --> 00:22:49,400 Speaker 1: to really take off, right, because it's expensive, it is, chuck, 374 00:22:49,440 --> 00:22:52,240 Speaker 1: how about a how about a message break? Huh hey, 375 00:22:52,400 --> 00:23:11,399 Speaker 1: let's do it alright. So, um, this whole idea of 376 00:23:11,440 --> 00:23:15,119 Speaker 1: going three fifty miles an hour through space even without 377 00:23:15,240 --> 00:23:19,480 Speaker 1: friction is um awesome. It is awesome. It can also 378 00:23:19,520 --> 00:23:23,000 Speaker 1: be deadly. They've they've already been maglev accidents. Yeah. The 379 00:23:23,040 --> 00:23:26,360 Speaker 1: one in Germany was a little distressing because in two 380 00:23:26,359 --> 00:23:29,040 Speaker 1: thousand and six it crashed into a repair car that 381 00:23:29,200 --> 00:23:33,000 Speaker 1: was accidentally left on the track, And this was a 382 00:23:33,000 --> 00:23:38,119 Speaker 1: test too, so it's like everything should have been Yeah, 383 00:23:38,480 --> 00:23:40,159 Speaker 1: like why do you leave a car on the track? Period? 384 00:23:40,480 --> 00:23:43,120 Speaker 1: I don't know, I don't know. Uh. So they actually 385 00:23:43,280 --> 00:23:45,520 Speaker 1: people died in that one. The train was going at 386 00:23:45,560 --> 00:23:47,280 Speaker 1: least a hundred and twenty miles an hour when it 387 00:23:47,359 --> 00:23:49,240 Speaker 1: struck the car, so it must have just been getting 388 00:23:49,320 --> 00:23:52,360 Speaker 1: up to speed, I guess. Yeah. But yeah, twenty nine 389 00:23:52,400 --> 00:23:55,119 Speaker 1: people died on that one. There was another one in 390 00:23:55,200 --> 00:23:58,760 Speaker 1: Shanghai on that line that is an operation. Yeah. That 391 00:23:58,840 --> 00:24:01,199 Speaker 1: was just a fire though, and I don't want to 392 00:24:01,240 --> 00:24:03,480 Speaker 1: make light of that, but it wasn't like a crash 393 00:24:03,720 --> 00:24:07,399 Speaker 1: or an incident like that. Yeah. I'm just glad no 394 00:24:07,440 --> 00:24:10,520 Speaker 1: one got hurt exactly. Uh. And this is breaking news, dude. 395 00:24:10,520 --> 00:24:13,720 Speaker 1: This was in the paper today as we record it 396 00:24:13,840 --> 00:24:18,720 Speaker 1: in real time. Okay, the Washington Post said that Northeast Maglev. 397 00:24:18,920 --> 00:24:22,720 Speaker 1: Everyone's getting in on the maglev game. Uh, because I mean, 398 00:24:22,760 --> 00:24:25,399 Speaker 1: like it really is a great idea. Yeah, it's just 399 00:24:25,600 --> 00:24:28,679 Speaker 1: really really expensive, but if you can get it up 400 00:24:28,720 --> 00:24:33,040 Speaker 1: and running, it's awesome. I Mean I imagine in literally 401 00:24:33,080 --> 00:24:35,320 Speaker 1: in a hundred years, there'll be a lot of this 402 00:24:35,760 --> 00:24:39,600 Speaker 1: as major transportation, you know, but not we won't see it. 403 00:24:40,040 --> 00:24:44,160 Speaker 1: But as of today November four, Northeast maglev is UH 404 00:24:45,280 --> 00:24:48,439 Speaker 1: has raised fifty million dollars in private funds. They can 405 00:24:48,480 --> 00:24:51,960 Speaker 1: build five inches of track with that exactly. And they're 406 00:24:52,000 --> 00:24:54,919 Speaker 1: trying to get the Washington Baltimore lag going with private 407 00:24:54,960 --> 00:24:57,920 Speaker 1: funding because the government's not pony any money for that. 408 00:24:58,080 --> 00:25:00,680 Speaker 1: I think we'll see it in our lifetime. They think 409 00:25:00,680 --> 00:25:04,040 Speaker 1: ten billion between d C and Baltimore. Yeah, um, although 410 00:25:04,080 --> 00:25:07,080 Speaker 1: they're not. They don't have a firm cost yet. But um, 411 00:25:07,119 --> 00:25:08,800 Speaker 1: I wonder how long it would take because I mean 412 00:25:08,840 --> 00:25:11,840 Speaker 1: that's not even that long of a drive anyway. Yeah, 413 00:25:11,960 --> 00:25:15,000 Speaker 1: I agreed. Let maybe maybe ten minutes, which I mean 414 00:25:15,040 --> 00:25:16,960 Speaker 1: if you live in Baltimore and work in d C. 415 00:25:17,160 --> 00:25:22,119 Speaker 1: I'm sure that would be extremely attractive. Yeah, that's true. Um, 416 00:25:22,160 --> 00:25:24,399 Speaker 1: I don't know about the Atlanta at Chattanooga thing. Who cares? 417 00:25:24,480 --> 00:25:27,800 Speaker 1: Yeah right, you know people in Chattanooga be psyched, I 418 00:25:27,800 --> 00:25:29,719 Speaker 1: guess because they could get to the airport in like 419 00:25:29,760 --> 00:25:34,200 Speaker 1: thirty minutes. Yeah, I guess, not just in Chattanooga. I'll 420 00:25:34,200 --> 00:25:36,560 Speaker 1: go there and pain for gold. I saw this, um 421 00:25:36,840 --> 00:25:40,440 Speaker 1: this it was some Discovery show video from a Discovery 422 00:25:40,440 --> 00:25:44,160 Speaker 1: show too, um, and it had our good friend Michio Kaku, 423 00:25:45,080 --> 00:25:49,520 Speaker 1: and he was talking about a train, bullet train that 424 00:25:49,640 --> 00:25:53,240 Speaker 1: could get you from one side of the world to 425 00:25:53,280 --> 00:25:56,919 Speaker 1: the other in an hour. Wow. And the way that 426 00:25:56,960 --> 00:25:58,960 Speaker 1: it would do that is to go through the middle 427 00:25:59,000 --> 00:26:02,919 Speaker 1: of the Earth. Basically, you would have to create this 428 00:26:03,080 --> 00:26:06,480 Speaker 1: to basically like Alon Musk's idea, you create a tube, 429 00:26:06,680 --> 00:26:10,080 Speaker 1: you evacuate all of the air out of it so 430 00:26:10,119 --> 00:26:13,520 Speaker 1: that there's no resistance whatsoever, and you just drop in 431 00:26:13,560 --> 00:26:16,080 Speaker 1: the force of gravity takes you up to about eighteen 432 00:26:16,119 --> 00:26:18,639 Speaker 1: thousand miles an hour, and then once you make it 433 00:26:18,680 --> 00:26:21,840 Speaker 1: to the center and out the other side, your gravity 434 00:26:21,880 --> 00:26:24,240 Speaker 1: starts to work against you, so it slows you down. 435 00:26:24,400 --> 00:26:27,199 Speaker 1: So within an hour you should be able to make 436 00:26:27,240 --> 00:26:29,320 Speaker 1: it from one side of the Earth to the other. 437 00:26:29,800 --> 00:26:34,399 Speaker 1: But as Dr Coku put put it, um, it's going 438 00:26:34,440 --> 00:26:36,760 Speaker 1: to be very difficult getting through the center of the Earth. 439 00:26:39,600 --> 00:26:41,840 Speaker 1: I love all these theoretical ideas these guys come up 440 00:26:41,880 --> 00:26:44,560 Speaker 1: with it like it's not even even then remotely possible. 441 00:26:45,640 --> 00:26:47,800 Speaker 1: And he'd probably said, like, I was just talking about 442 00:26:47,840 --> 00:26:50,200 Speaker 1: what they asked me to talk about. It's like, dude, 443 00:26:50,200 --> 00:26:51,960 Speaker 1: I was like McDonald's one day when I said that 444 00:26:53,000 --> 00:26:56,040 Speaker 1: I was waiting in line at McDonald's. So what else 445 00:26:56,080 --> 00:26:59,240 Speaker 1: you got? I got nothing else? Mag Lev? Yeah, the 446 00:26:59,280 --> 00:27:01,159 Speaker 1: way but the future. Yeah, we've got a we have 447 00:27:01,400 --> 00:27:04,600 Speaker 1: a standing bet. Now we will see a Maglev train 448 00:27:04,680 --> 00:27:07,080 Speaker 1: in operation that we can ride on while we're both alive. 449 00:27:07,160 --> 00:27:11,560 Speaker 1: That's my bet, you say now that we will, Like 450 00:27:11,760 --> 00:27:13,240 Speaker 1: I mean, if we went to Shanghai, we could do 451 00:27:13,280 --> 00:27:15,680 Speaker 1: it right now. So I feel like I just want 452 00:27:15,720 --> 00:27:17,639 Speaker 1: my bet health that you're gonna pay for us to 453 00:27:17,640 --> 00:27:22,480 Speaker 1: go to here in the United States. Um, within our lifetime, 454 00:27:23,240 --> 00:27:25,360 Speaker 1: which for me is gonna be about twenty years. We're 455 00:27:25,400 --> 00:27:28,600 Speaker 1: both still healthy enough to to ride it. Okay, I'll 456 00:27:28,640 --> 00:27:32,560 Speaker 1: take that bet. Okay. Uh, let's see. If you guys 457 00:27:32,640 --> 00:27:34,879 Speaker 1: want to learn more about Maglev, you can type that 458 00:27:34,920 --> 00:27:37,480 Speaker 1: word in the search part how stuff works dot Com. 459 00:27:37,560 --> 00:27:40,199 Speaker 1: And since I said a search part, it's time for 460 00:27:40,280 --> 00:27:44,439 Speaker 1: listener mail. That's right. This is I'm gonna call this 461 00:27:44,520 --> 00:27:50,680 Speaker 1: opportunity for students filmmaking students, So get your film on. Hey, 462 00:27:50,680 --> 00:27:54,600 Speaker 1: guys who work for nonprofit Antiquity Now, which is dedicated 463 00:27:54,640 --> 00:27:58,160 Speaker 1: to raising awareness of the importance of preserving our cult 464 00:27:58,240 --> 00:28:03,639 Speaker 1: cultural heritage by demonstrating how antiquities legacy influences and shapes 465 00:28:03,680 --> 00:28:05,840 Speaker 1: our lives today. Yeah, they have good stuff. We follow 466 00:28:05,880 --> 00:28:09,000 Speaker 1: them on Twitter. Oh you do nice? We do, Yes, 467 00:28:09,040 --> 00:28:11,160 Speaker 1: we do.

We thought you would be interested 469 00:28:13,720 --> 00:28:16,720 Speaker 1: and this upcoming project that we are holding the first 470 00:28:16,720 --> 00:28:21,280 Speaker 1: ever Legacy Quest International Children's Film and Video Festival, which 471 00:28:21,280 --> 00:28:24,639 Speaker 1: aims to get tweens and teens excited about history. The 472 00:28:24,720 --> 00:28:28,040 Speaker 1: festival will be held in conjunction with the Archaeology Channel 473 00:28:28,080 --> 00:28:34,679 Speaker 1: International Film and Video Festival on May nine through and Eugene, Oregon. 474 00:28:35,280 --> 00:28:38,280 Speaker 1: So here's what you gotta do, kids, young people, if 475 00:28:38,320 --> 00:28:41,040 Speaker 1: you're between twelve and fifteen, you can submit videos that 476 00:28:41,080 --> 00:28:45,520 Speaker 1: represent antiquities legacy in our contemporary life. For example, you 477 00:28:45,560 --> 00:28:48,280 Speaker 1: could depict how the invention of the wheel or calendar 478 00:28:48,680 --> 00:28:52,080 Speaker 1: has contributed to modern society, or how ancient methods of 479 00:28:52,080 --> 00:28:57,240 Speaker 1: solar energy have informed today's green technology. You got that. Yes, 480 00:28:57,880 --> 00:29:00,400 Speaker 1: Entries may be submitted by an individual student or by 481 00:29:00,440 --> 00:29:02,600 Speaker 1: a group or class under the guidance of a teacher. 482 00:29:03,080 --> 00:29:06,160 Speaker 1: As the festival was designed in accordance with the United 483 00:29:06,200 --> 00:29:09,960 Speaker 1: States National Curriculum standards for Social Studies, Legacy Quests would 484 00:29:09,960 --> 00:29:12,280 Speaker 1: be a great project for teachers to do with their classes. 485 00:29:13,040 --> 00:29:16,400 Speaker 1: Creating the video will support the development of literacy research skills, 486 00:29:16,680 --> 00:29:21,840 Speaker 1: writing skills, visual communication, and storytelling and they have prizes first, second, 487 00:29:21,880 --> 00:29:25,200 Speaker 1: and third prize among along with ten honorable mentions.
