00:00:00,200 --> 00:00:04,760
Speaker 1: Brought to you by the all new Toyota Corolla. Welcome

2
00:00:04,760 --> 00:00:14,280
Speaker 1: to Stuff you Should Know from House Stuff Works dot com. Hey,

3
00:00:14,360 --> 00:00:16,960
Speaker 1: and welcome to the podcast. I'm Josh Clark and there's

4
00:00:17,040 --> 00:00:26,279
Speaker 1: Charles W. Chuck Chuckers Briant. Yeah, and this is is

5
00:00:26,320 --> 00:00:29,080
Speaker 1: that where you're going with? Sure? Yeah, my bus right

6
00:00:29,160 --> 00:00:31,280
Speaker 1: into CC writer all the style. How are they going

7
00:00:31,360 --> 00:00:36,680
Speaker 1: with the Muppet? Oh? Yeah, it's time we put on makeup. Yeah?

8
00:00:37,760 --> 00:00:41,480
Speaker 1: What was that somebody's giant stomach stuffed bike? What was that?

9
00:00:41,960 --> 00:00:47,000
Speaker 1: That's weird? Yeah, that was crazy. That couldn't have been

10
00:00:47,080 --> 00:00:55,080
Speaker 1: Jerry's stomach. There's no way. All right, what's what's your intro? Huh? Chuck? Yes,

11
00:00:55,720 --> 00:01:01,040
Speaker 1: uh you remember our Magnet podcast. Yeah, I've personally thought

12
00:01:01,040 --> 00:01:05,120
Speaker 1: it was a great episode because we explained how magnets work. Yeah,

13
00:01:05,120 --> 00:01:09,400
Speaker 1: it was just good, tough but good. Yeah, it was tough,

14
00:01:09,400 --> 00:01:12,680
Speaker 1: but it was also kind of um. It was one

15
00:01:12,680 --> 00:01:15,280
Speaker 1: of those ones where you're like, oh, okay, that explains

16
00:01:15,319 --> 00:01:18,120
Speaker 1: pretty much everything about magnets, the thing that I've used

17
00:01:18,160 --> 00:01:20,480
Speaker 1: before in my life, and I just kind of took

18
00:01:20,520 --> 00:01:23,880
Speaker 1: for granted some people think that their magic, but we

19
00:01:24,040 --> 00:01:26,480
Speaker 1: kind of said, this is how they work. I liked it.

20
00:01:26,560 --> 00:01:32,760
Speaker 1: So um, I liked this this um article in theory,

21
00:01:33,640 --> 00:01:35,120
Speaker 1: the one we're about to do a show on. Yeah,

22
00:01:35,720 --> 00:01:38,920
Speaker 1: about maglev trains. Yeah, we did a video on maglev trains.

23
00:01:38,920 --> 00:01:43,480
Speaker 1: Remember that one of our one of our interstitial shorts

24
00:01:44,160 --> 00:01:50,320
Speaker 1: was on magleft trains. Uh do we I remember doing

25
00:01:50,320 --> 00:01:56,280
Speaker 1: the quantum levitation? Was that it? Yeah, because that's the

26
00:01:56,320 --> 00:01:58,400
Speaker 1: only way I knew about any of this was the

27
00:01:58,400 --> 00:01:59,760
Speaker 1: fact that we had talked about it before. Well what

28
00:01:59,800 --> 00:02:04,080
Speaker 1: did we talk about, uh magleb you know the basic

29
00:02:04,120 --> 00:02:07,360
Speaker 1: principle in one minute behind magnetic levitation. Well, that's pretty

30
00:02:07,440 --> 00:02:10,519
Speaker 1: much what we're gonna do here, except slightly longer. Yeah.

31
00:02:10,639 --> 00:02:15,040
Speaker 1: So that was my intro, but intro, and we should

32
00:02:15,040 --> 00:02:20,240
Speaker 1: say also, um, everyone, it is next to impossible to

33
00:02:20,400 --> 00:02:24,359
Speaker 1: get up to the minute, up to the year information

34
00:02:24,480 --> 00:02:30,400
Speaker 1: about what maglev trains are in operation, what are still planned,

35
00:02:30,480 --> 00:02:33,960
Speaker 1: what's still going on. So it is possible we may

36
00:02:34,320 --> 00:02:37,680
Speaker 1: get that part a little incorrect, but we're going to

37
00:02:37,720 --> 00:02:40,480
Speaker 1: try our best to be as accurate as possible. Yeah,

38
00:02:40,720 --> 00:02:44,200
Speaker 1: And the reason why is because magnetic levitation to power

39
00:02:44,240 --> 00:02:47,840
Speaker 1: a train so new. Well, it's actually not that new,

40
00:02:47,840 --> 00:02:49,400
Speaker 1: because they've been doing it for a while and well,

41
00:02:49,880 --> 00:02:53,080
Speaker 1: it was proposed ever since Tesla started noticing what was

42
00:02:53,120 --> 00:02:55,800
Speaker 1: going on in the late nineteenth century. But it's so

43
00:02:55,880 --> 00:03:00,680
Speaker 1: new in this regard as far as super fast speed

44
00:03:00,720 --> 00:03:06,880
Speaker 1: trains powered by magnets transporting lots of people over distances,

45
00:03:06,880 --> 00:03:10,000
Speaker 1: maybe great distances. That is so new, and there's so

46
00:03:10,240 --> 00:03:12,799
Speaker 1: a few different technologies that it is kind of hard

47
00:03:12,800 --> 00:03:14,639
Speaker 1: to keep track on which one is in the forefront,

48
00:03:15,240 --> 00:03:19,160
Speaker 1: which ones are being funded because the stuff is expensive.

49
00:03:19,680 --> 00:03:21,840
Speaker 1: It is, um, it's hard to get funding, especially here

50
00:03:21,840 --> 00:03:23,840
Speaker 1: in the States. Yeah, and if you go on if

51
00:03:23,840 --> 00:03:26,480
Speaker 1: you just type mag LEVI into Google or your favorite

52
00:03:26,520 --> 00:03:30,160
Speaker 1: search engine, um or duck duck go if you're you know,

53
00:03:31,080 --> 00:03:33,880
Speaker 1: kind of watching who's watching you? Oh? Is that like

54
00:03:33,880 --> 00:03:38,240
Speaker 1: a secret? It's like an anonymous search engine? Okay? Um,

55
00:03:38,480 --> 00:03:42,200
Speaker 1: you will find there's projects all over the United States,

56
00:03:42,360 --> 00:03:44,120
Speaker 1: and all of them are like, we're shove already, we're

57
00:03:44,120 --> 00:03:46,560
Speaker 1: ready to go. Just give us some money. And they're

58
00:03:46,560 --> 00:03:49,440
Speaker 1: not getting any money because the construction costs are so

59
00:03:49,640 --> 00:03:54,080
Speaker 1: enormous because with maglev trains you can't use existing railways.

60
00:03:54,640 --> 00:03:57,560
Speaker 1: It's all new. And uh, I saw one quote and

61
00:03:57,880 --> 00:04:01,120
Speaker 1: again who knows how recent this is, but fifty million

62
00:04:01,160 --> 00:04:03,960
Speaker 1: euros per mile. I can believe this is what the

63
00:04:04,000 --> 00:04:08,560
Speaker 1: German Consortium is quoting. The thing is is, once you

64
00:04:08,600 --> 00:04:12,840
Speaker 1: get it built, maintenance is not bad, not bad at all,

65
00:04:12,880 --> 00:04:14,680
Speaker 1: because there's not a lot of wear and tear on it.

66
00:04:14,720 --> 00:04:18,520
Speaker 1: As you'll see um and if you do look into

67
00:04:18,520 --> 00:04:20,800
Speaker 1: Maglav you will see that it is very much like

68
00:04:20,839 --> 00:04:26,680
Speaker 1: the the transportation technology of the future that's going on today. Um,

69
00:04:26,839 --> 00:04:31,880
Speaker 1: especially after looking into Elon Musk's um tube hyper loop thing.

70
00:04:33,160 --> 00:04:36,479
Speaker 1: I heard of that. So basically Elon Musk, who is

71
00:04:36,600 --> 00:04:40,160
Speaker 1: like our good friend, yeah, uh he super rich guy, right,

72
00:04:40,200 --> 00:04:42,640
Speaker 1: he basically just jotted down this idea on a cocktail

73
00:04:42,760 --> 00:04:44,560
Speaker 1: napkin and all of a sudden it's like the new thing.

74
00:04:45,240 --> 00:04:49,920
Speaker 1: But um, it's a an enclosed tube system that just

75
00:04:50,279 --> 00:04:53,960
Speaker 1: you put in a little car whatever that seats twelve

76
00:04:54,000 --> 00:04:57,440
Speaker 1: people or something comfortably and you suck all the air

77
00:04:57,480 --> 00:05:01,440
Speaker 1: out of it, no resist it, so you can go

78
00:05:01,839 --> 00:05:04,320
Speaker 1: really fast. Basically I think it goes about seven miles

79
00:05:04,360 --> 00:05:07,000
Speaker 1: an hour, a little under the speed of sound, so

80
00:05:07,040 --> 00:05:09,360
Speaker 1: you can get from the west coast to the east

81
00:05:09,400 --> 00:05:12,720
Speaker 1: coast or vice versa very very fast. The thing is

82
00:05:12,760 --> 00:05:19,279
Speaker 1: the construction costs for this are just preposterous. But if

83
00:05:20,200 --> 00:05:22,479
Speaker 1: it can come along or come down a little more,

84
00:05:22,720 --> 00:05:25,960
Speaker 1: then it will give Maglev a run for its money.

85
00:05:26,000 --> 00:05:29,400
Speaker 1: But if it, if Maglev can start to really kind

86
00:05:29,400 --> 00:05:32,720
Speaker 1: of get some traction and get some lines going, it

87
00:05:32,760 --> 00:05:35,400
Speaker 1: will be the the movement of the future for at

88
00:05:35,480 --> 00:05:39,679
Speaker 1: least a decade or two. Yeah, I saw where they're

89
00:05:39,680 --> 00:05:43,680
Speaker 1: proposing both in the future Maglev trains that operate inside

90
00:05:43,720 --> 00:05:47,680
Speaker 1: vacuum tubes. Okay, as fast as two thousand miles an

91
00:05:47,720 --> 00:05:51,800
Speaker 1: hour as crazy. Right now they're breaking records like an

92
00:05:51,800 --> 00:05:56,400
Speaker 1: hour plus what's the fastest right now? The so apparently,

93
00:05:56,440 --> 00:05:59,520
Speaker 1: and this is kind of mind boggling because Maglev as

94
00:05:59,600 --> 00:06:02,680
Speaker 1: again we realized everybody, we haven't explained what maglev is

95
00:06:02,680 --> 00:06:08,760
Speaker 1: we're talking here, but um, Maglev. The the great advantage

96
00:06:08,760 --> 00:06:12,000
Speaker 1: it has is that it's supposedly goes faster than the

97
00:06:12,160 --> 00:06:16,599
Speaker 1: normal steel wheel train apparently a TGV train, which is

98
00:06:16,600 --> 00:06:21,640
Speaker 1: a steel wheel train. UM. In Europe, they they beat

99
00:06:21,839 --> 00:06:24,359
Speaker 1: a Maglev land speed really that was held by the

100
00:06:24,480 --> 00:06:28,360
Speaker 1: Japanese Maglev of about three hundred and fifty one mile

101
00:06:28,480 --> 00:06:30,680
Speaker 1: an hour. I think it went like three sixty. Man,

102
00:06:30,720 --> 00:06:33,960
Speaker 1: I don't know if i'd feel safe. Yeah, I can imagine.

103
00:06:34,080 --> 00:06:36,080
Speaker 1: I was. I was reading a quote from a Maglev

104
00:06:36,240 --> 00:06:39,599
Speaker 1: rider and they were saying, like, you can tell you're

105
00:06:39,600 --> 00:06:43,800
Speaker 1: going really fast, like on the bullet train. You was

106
00:06:43,839 --> 00:06:45,880
Speaker 1: gonna be so disappointed because she's taught me how to

107
00:06:45,920 --> 00:06:48,400
Speaker 1: say it in Japanese so many times that I don't

108
00:06:48,440 --> 00:06:52,080
Speaker 1: want to butcher. But the bullet train, it goes pretty fast,

109
00:06:52,560 --> 00:06:55,000
Speaker 1: like hundred and fifty miles an hour or something, but

110
00:06:55,480 --> 00:06:58,480
Speaker 1: it just looks like everything's a blur. You don't feel

111
00:06:58,520 --> 00:07:01,200
Speaker 1: like you're going fast. Apparently in a Maglev it goes

112
00:07:01,240 --> 00:07:03,600
Speaker 1: fast enough to wear like you feel like, holy cow,

113
00:07:03,920 --> 00:07:06,800
Speaker 1: we're going three fifty miles an hour. Well, our very

114
00:07:06,880 --> 00:07:10,840
Speaker 1: unparent company did a show World's Fastest Trains, and I

115
00:07:10,880 --> 00:07:14,240
Speaker 1: watched the Maglev segment and the dude you know, was

116
00:07:14,280 --> 00:07:16,000
Speaker 1: in the front room with the driver and they were like,

117
00:07:16,000 --> 00:07:17,880
Speaker 1: all right, we're going three hundred miles an hour now,

118
00:07:18,280 --> 00:07:20,680
Speaker 1: and it's hard to tell on the TV you know

119
00:07:21,640 --> 00:07:23,600
Speaker 1: exactly how fast you're going because I looked and I

120
00:07:23,640 --> 00:07:25,360
Speaker 1: was like, well, then, you know, it looks like about

121
00:07:25,360 --> 00:07:28,200
Speaker 1: a hundred to me. But um, yeah, I think being

122
00:07:28,240 --> 00:07:30,040
Speaker 1: on the train and I think the key to not

123
00:07:30,080 --> 00:07:33,120
Speaker 1: feeling too weird is obviously you're not being shot out

124
00:07:33,120 --> 00:07:35,160
Speaker 1: like a bullet. You're you're ramping up to that speed,

125
00:07:35,560 --> 00:07:37,680
Speaker 1: so that helps. Plus if you dressed normally for your

126
00:07:37,720 --> 00:07:41,400
Speaker 1: train ride, you'll feel less weird too. That's right. Um. Also,

127
00:07:41,480 --> 00:07:45,520
Speaker 1: hold on one more thing, um, the we're talking very

128
00:07:45,600 --> 00:07:52,000
Speaker 1: high speeds an that's the that's the speed record of

129
00:07:52,040 --> 00:07:55,840
Speaker 1: a maglev. But they're averaging like to fifty or more,

130
00:07:56,520 --> 00:07:59,280
Speaker 1: which means if you, if you get these things built,

131
00:07:59,600 --> 00:08:01,920
Speaker 1: you're going to expand the range of where people can

132
00:08:02,000 --> 00:08:06,760
Speaker 1: live and commute and go to work every day tremendously. Um.

133
00:08:06,840 --> 00:08:09,400
Speaker 1: So there's a lot of value in creating these maglevs.

134
00:08:09,880 --> 00:08:13,440
Speaker 1: Right are we there yet? Well, before we do that,

135
00:08:14,000 --> 00:08:16,160
Speaker 1: let's just might as well do a message break now, huh.

136
00:08:16,240 --> 00:08:23,680
Speaker 1: I think it's a good time, all right, So now

137
00:08:23,720 --> 00:08:29,600
Speaker 1: can we get down to brass tacks. Let's okay. Um,

138
00:08:29,640 --> 00:08:31,720
Speaker 1: this is kind of confusing because I read a paper

139
00:08:31,760 --> 00:08:35,800
Speaker 1: in ight, I think where this guy was saying like

140
00:08:35,840 --> 00:08:38,920
Speaker 1: there's a lot of people calling all these different technologies maglev.

141
00:08:39,640 --> 00:08:44,520
Speaker 1: This is all very early stage proposal hadn't been proven yet,

142
00:08:45,040 --> 00:08:47,040
Speaker 1: but he was saying there's at least seven different kinds

143
00:08:47,040 --> 00:08:49,880
Speaker 1: of technology here that everyone's calling maglev that are different

144
00:08:50,000 --> 00:08:53,200
Speaker 1: enough that it doesn't they're just different. But for the

145
00:08:53,240 --> 00:08:56,160
Speaker 1: purposes of this podcast, we can get it with maglev,

146
00:08:56,480 --> 00:08:59,040
Speaker 1: but we have to point out that there are some

147
00:08:59,120 --> 00:09:03,479
Speaker 1: really different systems that are in use and being proposed

148
00:09:03,559 --> 00:09:05,480
Speaker 1: right now, and a lot of them have to do

149
00:09:05,600 --> 00:09:10,160
Speaker 1: with the suspension system. Yeah, I think what's going on now?

150
00:09:10,559 --> 00:09:16,160
Speaker 1: There are three pretty much leading competing systems, right. Yeah,

151
00:09:16,200 --> 00:09:19,400
Speaker 1: because we should say, chuck. A maglev train is a

152
00:09:19,400 --> 00:09:24,040
Speaker 1: train that uses magnets to float above a track by

153
00:09:24,200 --> 00:09:27,079
Speaker 1: either a half a centimeter too. I saw one that

154
00:09:27,200 --> 00:09:29,440
Speaker 1: floats up to a foot off the track. That's a

155
00:09:29,440 --> 00:09:31,800
Speaker 1: little scary. It seems a little scary, but apparently the

156
00:09:31,880 --> 00:09:34,720
Speaker 1: higher you go, and that that high end of the range,

157
00:09:35,040 --> 00:09:38,840
Speaker 1: the more stable it is. Yeah. But so the the

158
00:09:38,880 --> 00:09:42,800
Speaker 1: train is literally not touching the tracks and it floats along.

159
00:09:42,880 --> 00:09:45,319
Speaker 1: And the reason that's why it can go so fast

160
00:09:45,360 --> 00:09:48,680
Speaker 1: is because there's no friction, no friction, The only resistance

161
00:09:48,760 --> 00:09:52,120
Speaker 1: is air and they're super sleek of course, so even

162
00:09:52,120 --> 00:09:54,760
Speaker 1: the error is cut down. Uh. So let's go. Let's

163
00:09:54,760 --> 00:09:58,080
Speaker 1: go to Germany first, because they have a system, uh

164
00:09:59,040 --> 00:10:02,600
Speaker 1: trans rapid it's called the actually company is called trans

165
00:10:02,679 --> 00:10:05,600
Speaker 1: Rapid International. There's also a trans Rapid USA now I

166
00:10:05,600 --> 00:10:10,679
Speaker 1: think us. That's right. Uh. And the German version is

167
00:10:10,800 --> 00:10:15,240
Speaker 1: electro magnetic suspension. And the way that the guy on

168
00:10:15,280 --> 00:10:20,720
Speaker 1: the Discovery Channel show described it was that electro magnets, Well,

169
00:10:20,720 --> 00:10:24,800
Speaker 1: when you use electromagnets, they're only um magnetize when there's

170
00:10:24,800 --> 00:10:29,360
Speaker 1: a power source, when there's electricity running through exactly. So

171
00:10:29,400 --> 00:10:31,880
Speaker 1: that's important to remember it is, and we'll point out

172
00:10:31,880 --> 00:10:35,800
Speaker 1: why later, because in the German system, uh, the E

173
00:10:35,920 --> 00:10:39,600
Speaker 1: M S system, it's all about attraction. It's not repelled

174
00:10:39,640 --> 00:10:43,040
Speaker 1: magnets repelling each other. It's magnets that are attracted to

175
00:10:43,080 --> 00:10:47,240
Speaker 1: each other. And the reason that they float is they're

176
00:10:47,240 --> 00:10:51,440
Speaker 1: basically switching it on and off, pulsing the electromatic magnets

177
00:10:51,480 --> 00:10:57,640
Speaker 1: so fast that it creates that hovering attraction. Okay, so

178
00:10:57,760 --> 00:11:02,680
Speaker 1: that's the German version, so um okay. And apparently this

179
00:11:02,760 --> 00:11:05,640
Speaker 1: German version, I think they do use repulsive magnets, but

180
00:11:05,720 --> 00:11:09,880
Speaker 1: on the sides for the guidance magnets, so to make

181
00:11:09,920 --> 00:11:12,720
Speaker 1: it hover, they're turning it on an awful lot. So

182
00:11:12,800 --> 00:11:15,080
Speaker 1: it wants to stick, but no, but stick but no,

183
00:11:15,480 --> 00:11:17,040
Speaker 1: and there's not a dude on the switch doing it

184
00:11:17,080 --> 00:11:21,800
Speaker 1: really fast. It's right. They have computers handling it UM.

185
00:11:21,880 --> 00:11:24,679
Speaker 1: And then so this is the the suspension system you're

186
00:11:24,679 --> 00:11:29,000
Speaker 1: talking about, right, the electro magnetic suspension. And the word

187
00:11:29,040 --> 00:11:31,760
Speaker 1: suspension is kind of easily overlooked, but in this case

188
00:11:31,800 --> 00:11:35,679
Speaker 1: we're literally talking about how the train is suspended in

189
00:11:36,000 --> 00:11:39,679
Speaker 1: mid air above the track in this case, and with

190
00:11:39,800 --> 00:11:43,320
Speaker 1: the e M S it's about I think half a

191
00:11:43,360 --> 00:11:46,760
Speaker 1: centimeter to a centimeter. It's it's very close to the

192
00:11:46,840 --> 00:11:50,040
Speaker 1: to the track, and they use the electro magnets to

193
00:11:50,280 --> 00:11:53,880
Speaker 1: attract and they use the guidance magnets, which are magnets

194
00:11:53,960 --> 00:11:58,360
Speaker 1: installed on the side of the train UH that are

195
00:11:58,480 --> 00:12:02,000
Speaker 1: along the side of the track to repel magnets along

196
00:12:02,040 --> 00:12:05,240
Speaker 1: the side of the track to keep the train from

197
00:12:05,360 --> 00:12:10,240
Speaker 1: bumping into the guide rails. But it requires a UH

198
00:12:10,880 --> 00:12:15,120
Speaker 1: computer system to constantly make adjustments to the current that's

199
00:12:15,160 --> 00:12:19,880
Speaker 1: going through these electro magnets to either um to either

200
00:12:19,920 --> 00:12:22,920
Speaker 1: attract the train to make it float or to repel

201
00:12:22,960 --> 00:12:25,079
Speaker 1: it from the sides to adjust it to make sure

202
00:12:25,080 --> 00:12:27,640
Speaker 1: it never bumps into the rails or the track. Because

203
00:12:27,679 --> 00:12:30,960
Speaker 1: if you're going three fifty miles an hour and your

204
00:12:31,000 --> 00:12:35,040
Speaker 1: train scuffs the track, you're in big trouble or big trouble.

205
00:12:35,600 --> 00:12:38,840
Speaker 1: One advantage of this, uh the German system, is that

206
00:12:39,360 --> 00:12:41,520
Speaker 1: you only need the power on for the section of

207
00:12:41,520 --> 00:12:45,400
Speaker 1: track that you're using at the time. So they literally

208
00:12:46,240 --> 00:12:49,560
Speaker 1: will turn on a section of track, the train goes

209
00:12:49,600 --> 00:12:51,360
Speaker 1: over it, and then they'll turn it back off. Right,

210
00:12:51,440 --> 00:12:55,320
Speaker 1: So it's very like economically fuel will not fuel efficient

211
00:12:55,360 --> 00:12:58,439
Speaker 1: because it's not fuel right, and that's the power efficient right,

212
00:12:58,520 --> 00:13:01,360
Speaker 1: And it doesn't use fossil fuel in the sense that

213
00:13:01,480 --> 00:13:04,000
Speaker 1: a normal train does, although if you go far enough

214
00:13:04,000 --> 00:13:06,800
Speaker 1: down the line, that electricity has to come from somewhere,

215
00:13:06,800 --> 00:13:10,760
Speaker 1: so ultimately it is coming from possibles. But the efficiency

216
00:13:11,000 --> 00:13:15,320
Speaker 1: fuel efficiency is incredible compared to you know, a normal

217
00:13:15,880 --> 00:13:20,280
Speaker 1: train that burns cossal fuels just to move God's shoveling

218
00:13:20,280 --> 00:13:23,280
Speaker 1: coal into a fire. Yeah, yeah, I should say so.

219
00:13:23,679 --> 00:13:29,360
Speaker 1: My understanding of the delivery of electricity to the track

220
00:13:29,520 --> 00:13:32,880
Speaker 1: is the same for both suspension systems that you propel

221
00:13:33,000 --> 00:13:37,200
Speaker 1: like that. So the whole track is made of electromagnets

222
00:13:37,320 --> 00:13:43,040
Speaker 1: right from on both systems, and you're just sending electricity

223
00:13:43,080 --> 00:13:46,120
Speaker 1: to the electromagnets that are immediately in front of and

224
00:13:46,120 --> 00:13:51,520
Speaker 1: immediately behind the train immediately under. Yeah, because you need it.

225
00:13:51,559 --> 00:13:52,920
Speaker 1: You need to float the train. Then you need to

226
00:13:52,960 --> 00:13:55,080
Speaker 1: propel it right, and the way you're propelling it is

227
00:13:55,120 --> 00:13:57,960
Speaker 1: the magnets that are just ahead of the train are

228
00:13:58,160 --> 00:14:01,720
Speaker 1: going to be positive, and so that's going to attract

229
00:14:01,720 --> 00:14:04,559
Speaker 1: the train, meaning it's gonna pull it forward. And then

230
00:14:04,600 --> 00:14:07,400
Speaker 1: the the magnets behind it are gonna be charged so

231
00:14:07,480 --> 00:14:11,160
Speaker 1: that they're negative and they're going to repel the train

232
00:14:11,559 --> 00:14:14,319
Speaker 1: push it. So in the front, the magnets are pulling

233
00:14:14,320 --> 00:14:17,000
Speaker 1: it in the in the back, the magnets are pushing it.

234
00:14:17,320 --> 00:14:20,720
Speaker 1: And again, remember there's no friction here, it's just air.

235
00:14:21,480 --> 00:14:23,760
Speaker 1: So it doesn't take a whole lot to make this

236
00:14:23,840 --> 00:14:27,280
Speaker 1: train go really really fast just using magnets. Yeah, and

237
00:14:27,320 --> 00:14:32,280
Speaker 1: they in two thousand two debuted commercially in Shanghai, China,

238
00:14:32,560 --> 00:14:37,080
Speaker 1: a pretty short run transporting people um from airport to

239
00:14:37,120 --> 00:14:40,800
Speaker 1: airport basically um at a speed it speeds over two

240
00:14:41,200 --> 00:14:44,120
Speaker 1: fifty miles an hour. So I read that the journey

241
00:14:44,160 --> 00:14:45,960
Speaker 1: the nineteen mile journey. Now it takes about seven and

242
00:14:45,960 --> 00:14:48,280
Speaker 1: a half minutes as opposed to about an hour in

243
00:14:48,320 --> 00:14:52,480
Speaker 1: a cab, and they were going to expand it, but

244
00:14:53,120 --> 00:14:57,000
Speaker 1: that was halted in two thousand eight over radiation fears

245
00:14:57,560 --> 00:15:02,440
Speaker 1: by people, And now it's being proposed as an underground system,

246
00:15:03,440 --> 00:15:06,280
Speaker 1: like to go underground to halt those fears. But in

247
00:15:06,320 --> 00:15:09,200
Speaker 1: two thousand and ten another high speed train in the

248
00:15:09,280 --> 00:15:13,720
Speaker 1: area was a non maglev system opened, so they basically said, well,

249
00:15:13,760 --> 00:15:16,240
Speaker 1: we probably won't do this. Uh, we probably won't extend

250
00:15:16,240 --> 00:15:18,680
Speaker 1: the Shanghai line now. So yeah, I heard it's definitely

251
00:15:18,720 --> 00:15:21,520
Speaker 1: on hold, but I didn't hear that they decided they

252
00:15:21,560 --> 00:15:25,880
Speaker 1: weren't going to do it. Well, the regular bullet train

253
00:15:26,680 --> 00:15:28,800
Speaker 1: popped up and they're like, well, now that we have that,

254
00:15:28,840 --> 00:15:31,720
Speaker 1: I guess we don't need the maglev. Oh well, oh well,

255
00:15:32,120 --> 00:15:37,440
Speaker 1: so Japan's got the other um big rival system. Uh

256
00:15:37,640 --> 00:15:40,160
Speaker 1: So the propulsion systems are the same. You use magnets

257
00:15:40,240 --> 00:15:42,320
Speaker 1: ahead of the train and behind the train to attract

258
00:15:42,360 --> 00:15:44,960
Speaker 1: a repel it right to push it forward. I believe so,

259
00:15:44,960 --> 00:15:49,080
Speaker 1: so um the suspension systems are what differ. In Germany

260
00:15:49,400 --> 00:15:53,400
Speaker 1: you're using magnets to um repel it right, to attract

261
00:15:53,400 --> 00:15:56,600
Speaker 1: it to attract it. In Japan you're using something called

262
00:15:56,640 --> 00:15:59,840
Speaker 1: the Meisner effect. So basically, Chuck The Meisner effect is

263
00:16:00,200 --> 00:16:05,800
Speaker 1: where you take a super cooled superconductor, right, I think

264
00:16:05,840 --> 00:16:10,120
Speaker 1: like liquid helium temperature, which is very very cold, and

265
00:16:10,200 --> 00:16:13,440
Speaker 1: you put it in a magnetic field. The magnetic field

266
00:16:13,840 --> 00:16:20,480
Speaker 1: basically hugs it. It goes around it rather than through it. Okay, Um,

267
00:16:20,520 --> 00:16:25,160
Speaker 1: So when you do that, the field actually levitates the thing.

268
00:16:26,400 --> 00:16:29,240
Speaker 1: So if you take enough superconductors that are at the

269
00:16:29,320 --> 00:16:33,720
Speaker 1: right temperature and you put them in the presence of

270
00:16:33,760 --> 00:16:38,040
Speaker 1: a magnetic field whole bunch of magnets, say on a train,

271
00:16:38,960 --> 00:16:44,000
Speaker 1: the the magnet will float, it will levitate, And that's

272
00:16:44,080 --> 00:16:49,360
Speaker 1: the electrodynamics expension that the Japanese are using. So basically

273
00:16:49,400 --> 00:16:53,000
Speaker 1: you have a tunnel, a magnetic field tunnel that these

274
00:16:53,000 --> 00:16:56,600
Speaker 1: things are traveling through, which means that there they don't

275
00:16:56,760 --> 00:16:59,280
Speaker 1: they don't need any extra magnets on the sides, or

276
00:16:59,320 --> 00:17:01,680
Speaker 1: they don't need any on the bottom or extra magnets

277
00:17:01,720 --> 00:17:04,840
Speaker 1: on the bottom. It's just going to stay put within

278
00:17:05,000 --> 00:17:08,680
Speaker 1: this bent magnetic field that's warped to wrap around it.

279
00:17:09,200 --> 00:17:12,560
Speaker 1: That's right. It's never going to drop and it's totally stable,

280
00:17:12,960 --> 00:17:15,840
Speaker 1: which is the big that's a big advantage from what

281
00:17:15,880 --> 00:17:18,359
Speaker 1: I understand of the Japanese system over the German system.

282
00:17:18,600 --> 00:17:22,359
Speaker 1: The stability doesn't require a bunch of computers to constantly

283
00:17:22,400 --> 00:17:26,280
Speaker 1: adjust it, and it is just inherently more stable because

284
00:17:26,680 --> 00:17:29,080
Speaker 1: it's not just being held up from the bottom and

285
00:17:29,119 --> 00:17:31,560
Speaker 1: then a little on the sides. It is wrapped in

286
00:17:31,640 --> 00:17:37,399
Speaker 1: this basically blanket of an electro magnetic field UH. It

287
00:17:37,720 --> 00:17:41,680
Speaker 1: can conduct power electricity even when the power is cut off,

288
00:17:41,680 --> 00:17:44,680
Speaker 1: so that's a definite advantage UM. Although the German system

289
00:17:44,720 --> 00:17:47,040
Speaker 1: does have like battery backups, it's not like if the

290
00:17:47,040 --> 00:17:49,560
Speaker 1: power went off, the train would just go and stop.

291
00:17:50,720 --> 00:17:54,159
Speaker 1: But the German one doesn't never doesn't need tires, and

292
00:17:54,160 --> 00:17:56,680
Speaker 1: the Japanese one does, yeah, because it needs to ramp

293
00:17:56,760 --> 00:17:59,239
Speaker 1: up to a certain speed in order to begin the

294
00:17:59,240 --> 00:18:02,080
Speaker 1: float and just start immediately. What is it like eighty

295
00:18:02,080 --> 00:18:05,600
Speaker 1: eight miles per hour. That's back to the future sixty two.

296
00:18:07,040 --> 00:18:09,639
Speaker 1: And I think they use liquid nitrogen and it's just

297
00:18:09,800 --> 00:18:14,360
Speaker 1: expensive to super cool these UH coils, and I think

298
00:18:14,359 --> 00:18:17,920
Speaker 1: that's one of the drawbacks. But they're all expensive. They're

299
00:18:18,560 --> 00:18:20,760
Speaker 1: none of this is they haven't figured out a cheap

300
00:18:20,800 --> 00:18:24,159
Speaker 1: way to do any of this. Now, there's a proposed

301
00:18:24,200 --> 00:18:27,679
Speaker 1: line um in Japan. It's already it's the one that

302
00:18:27,800 --> 00:18:32,240
Speaker 1: set the uh that land speed record for maglev trains.

303
00:18:32,880 --> 00:18:37,320
Speaker 1: It's the j R tok Um that's the railway company,

304
00:18:37,440 --> 00:18:41,560
Speaker 1: the JRR Tolkien kind of close, but it's their line. Um,

305
00:18:41,760 --> 00:18:45,000
Speaker 1: it's supposed supposedly is already in operation. I read somewhere

306
00:18:45,040 --> 00:18:47,880
Speaker 1: that it's moved like a million people already. But they

307
00:18:47,880 --> 00:18:50,119
Speaker 1: have a proposed line that they want to open by

308
00:18:51,000 --> 00:18:54,760
Speaker 1: seven and it's from Tokyo to Nagoya, and then they

309
00:18:54,760 --> 00:19:00,280
Speaker 1: want to extend that from Tokyo to Osaka. And they're

310
00:19:00,320 --> 00:19:03,800
Speaker 1: talking like it's like a fifty billion dollar project and

311
00:19:03,800 --> 00:19:07,199
Speaker 1: I think that's just the first line. That's Yeah, it

312
00:19:07,200 --> 00:19:09,600
Speaker 1: sounds about right. But the reason that it probably will

313
00:19:09,640 --> 00:19:13,080
Speaker 1: happen is they're they're um facing all of this on

314
00:19:13,240 --> 00:19:16,919
Speaker 1: data showing that people are going to keep moving to

315
00:19:17,000 --> 00:19:20,000
Speaker 1: Japan and Osaka, so they're going to have customers and

316
00:19:20,040 --> 00:19:22,280
Speaker 1: they're not relying on any government money. They have so

317
00:19:22,359 --> 00:19:24,760
Speaker 1: much money they're just going to fund it themselves. Is

318
00:19:24,800 --> 00:19:28,160
Speaker 1: privately funded. Yeah. Yeah. Another con though of the Japanese

319
00:19:28,240 --> 00:19:30,480
Speaker 1: version is that if you have a pacemaker, you don't

320
00:19:30,480 --> 00:19:34,080
Speaker 1: want to get on that train because, um, that magnetic

321
00:19:34,119 --> 00:19:38,760
Speaker 1: field will reek havoc and you probably won't live. It

322
00:19:38,760 --> 00:19:41,400
Speaker 1: will shut you down. We'll shut you down. And then

323
00:19:41,400 --> 00:19:45,520
Speaker 1: there's the in duct track and that is another type

324
00:19:45,520 --> 00:19:48,360
Speaker 1: of E d S system, which is the Japanese system,

325
00:19:48,680 --> 00:19:52,439
Speaker 1: except that they use room temperature magnets. And from what

326
00:19:52,480 --> 00:19:57,320
Speaker 1: I could tell, this is as close to just the

327
00:19:57,680 --> 00:20:03,280
Speaker 1: whole thing of magnets, regular magnets opposing each other, and

328
00:20:03,320 --> 00:20:06,240
Speaker 1: they're just gonna use that, right, Yeah, Like it's as

329
00:20:06,240 --> 00:20:07,879
Speaker 1: close do we get as you going out to the

330
00:20:07,920 --> 00:20:12,040
Speaker 1: store and getting two magnets and putting their like poles

331
00:20:12,080 --> 00:20:14,919
Speaker 1: against each other so that they repel. Yeah, there's actually

332
00:20:14,920 --> 00:20:17,520
Speaker 1: something called the hull Bock array, which is a way

333
00:20:17,560 --> 00:20:20,679
Speaker 1: to just line up the magnets UM in certain directions

334
00:20:20,680 --> 00:20:24,399
Speaker 1: so that their poles are facing north, southeast or west. UM.

335
00:20:24,480 --> 00:20:27,800
Speaker 1: And when you put them together in a clump, basically,

336
00:20:27,880 --> 00:20:34,760
Speaker 1: the the magnetic field below the magnets doubles, the magnetic

337
00:20:34,800 --> 00:20:37,760
Speaker 1: field on the top of the magnets cancels one another out,

338
00:20:38,359 --> 00:20:41,639
Speaker 1: so you have your extra strong magnetic magnetic field that

339
00:20:41,680 --> 00:20:46,240
Speaker 1: can produce this Misner effect basically um without this super

340
00:20:46,320 --> 00:20:49,920
Speaker 1: cooled superconductor. Yeah, and these aren't even electro magnets. I

341
00:20:49,920 --> 00:20:52,160
Speaker 1: don't think aren't they just magnets. I think they're permanent

342
00:20:52,280 --> 00:20:56,440
Speaker 1: room temperature magnets. Is crazy. Yeah, there are three UM

343
00:20:56,600 --> 00:20:59,639
Speaker 1: designs right now the in duct track one, two, and three.

344
00:21:00,400 --> 00:21:04,399
Speaker 1: UM one is high speed, two is slow speed, and

345
00:21:04,520 --> 00:21:08,320
Speaker 1: three is heavy load slow speed. Yeah, so I guess

346
00:21:08,359 --> 00:21:11,359
Speaker 1: just freighting stuff back and forth. Yeah. They did this

347
00:21:11,400 --> 00:21:13,320
Speaker 1: in London at one point, but then shut it down.

348
00:21:13,359 --> 00:21:16,280
Speaker 1: Like in the eighties, they had a maglive train. Yeah,

349
00:21:16,400 --> 00:21:18,919
Speaker 1: just a very slow moving like it might have been

350
00:21:18,960 --> 00:21:21,879
Speaker 1: an airport type situation. And I looked up the one

351
00:21:21,880 --> 00:21:25,320
Speaker 1: here in Atlanta, the new airport train. I thought it

352
00:21:25,359 --> 00:21:27,200
Speaker 1: might have been maglev, but of course it's not. It's

353
00:21:27,240 --> 00:21:32,200
Speaker 1: just wheels, just stupid wheels. UM. Although they had Atlanta

354
00:21:32,240 --> 00:21:34,879
Speaker 1: have its day, Well, they have proposed one. Atlanta is

355
00:21:34,880 --> 00:21:37,720
Speaker 1: one of the city's UM that's trying to get maglev

356
00:21:37,800 --> 00:21:41,920
Speaker 1: going between Atlanta and Chattanooga. And there's one proposed between

357
00:21:42,040 --> 00:21:45,240
Speaker 1: d C and Baltimore. One in Las Vegas, Yeah, La

358
00:21:45,240 --> 00:21:50,200
Speaker 1: in Vegas UM, and I think one from Pittsburgh to someplace,

359
00:21:51,400 --> 00:21:54,360
Speaker 1: but I'm not sure exactly where I saw that one too.

360
00:21:54,359 --> 00:21:58,399
Speaker 1: I don't remember where it might have been d C Stittsburg, Philly, yeah, well,

361
00:21:58,400 --> 00:22:01,080
Speaker 1: hold on, we're getting ahead of ourselves. Well, no, these

362
00:22:01,080 --> 00:22:03,359
Speaker 1: are just proposals and and they're having a hard time

363
00:22:03,760 --> 00:22:05,680
Speaker 1: getting the funding they need for any of these to

364
00:22:05,720 --> 00:22:10,680
Speaker 1: really take off, right, because it's expensive, it is chuck,

365
00:22:10,720 --> 00:22:13,520
Speaker 1: how about a how about a message break? Huh hey,

366
00:22:13,680 --> 00:22:23,239
Speaker 1: let's do it alright. So, um, this whole idea of

367
00:22:23,280 --> 00:22:26,960
Speaker 1: going three fifty miles an hour through space even without

368
00:22:27,080 --> 00:22:31,280
Speaker 1: friction is um awesome, It is awesome. It can also

369
00:22:31,320 --> 00:22:34,840
Speaker 1: be deadly. They've they've already been maglev accidents. Yeah, the

370
00:22:34,880 --> 00:22:38,200
Speaker 1: one in Germany was a little distressing because in two

371
00:22:38,200 --> 00:22:40,879
Speaker 1: thousand and six it crashed into a repair car that

372
00:22:41,040 --> 00:22:44,840
Speaker 1: was accidentally left on the track. And this is a

373
00:22:44,840 --> 00:22:50,040
Speaker 1: test too, so it's like everything should have been Yeah,

374
00:22:50,320 --> 00:22:52,040
Speaker 1: like why do you leave a car on the track? Period?

375
00:22:52,320 --> 00:22:54,960
Speaker 1: I don't know, I don't know. Uh So they actually

376
00:22:55,119 --> 00:22:57,359
Speaker 1: people died in that one. The train was going at

377
00:22:57,400 --> 00:22:59,119
Speaker 1: least a hundred and twenty miles an hour when it

378
00:22:59,200 --> 00:23:01,320
Speaker 1: struck the car. We must have just been getting up

379
00:23:01,400 --> 00:23:04,520
Speaker 1: to speed, I guess, yeah, but yeah, twenty nine people

380
00:23:04,560 --> 00:23:08,320
Speaker 1: died on that one. There's another one in Shanghai on

381
00:23:08,400 --> 00:23:10,879
Speaker 1: that line that is an operation. Yeah, that was just

382
00:23:10,920 --> 00:23:13,480
Speaker 1: a fire though, and I don't want to make light

383
00:23:13,520 --> 00:23:15,880
Speaker 1: of that, but it wasn't like a crash or an

384
00:23:15,880 --> 00:23:19,640
Speaker 1: incident like that. Yeah, I'm just glad no one got

385
00:23:19,720 --> 00:23:22,439
Speaker 1: hurt exactly. Uh. And this is breaking news, dude. This

386
00:23:22,560 --> 00:23:25,760
Speaker 1: was in the paper today as we record it in

387
00:23:25,840 --> 00:23:30,560
Speaker 1: real time. Okay. The Washington Post said that Northeast Maglev

388
00:23:30,760 --> 00:23:34,119
Speaker 1: everyone's getting in on the mag Love game. Uh, because

389
00:23:34,320 --> 00:23:37,080
Speaker 1: I mean, like, it really is a great idea. It's

390
00:23:37,119 --> 00:23:40,280
Speaker 1: just really really expensive, but if you can get it

391
00:23:40,400 --> 00:23:43,960
Speaker 1: up and running, it's awesome. I Mean I imagine in

392
00:23:44,440 --> 00:23:47,000
Speaker 1: literally in a hundred years, there'll be a lot of

393
00:23:47,040 --> 00:23:51,040
Speaker 1: this as major transportation, you know, but not we won't

394
00:23:51,040 --> 00:23:54,400
Speaker 1: see it. But as of today, November four, Northeast mag

395
00:23:54,480 --> 00:23:59,639
Speaker 1: Love is AH has raised fifty million dollars in private funds.

396
00:24:00,040 --> 00:24:02,960
Speaker 1: They can build five inches of track with that exactly.

397
00:24:03,400 --> 00:24:06,200
Speaker 1: And they're trying to get the Washington Baltimore lag going

398
00:24:06,240 --> 00:24:09,600
Speaker 1: with private funding because the government's not pony any money

399
00:24:09,600 --> 00:24:11,760
Speaker 1: for it. I think we'll see it in our lifetime.

400
00:24:12,160 --> 00:24:15,879
Speaker 1: They think ten billion between d C and Baltimore, although

401
00:24:15,920 --> 00:24:18,920
Speaker 1: they're not They don't have a firm cost yet, but um,

402
00:24:18,920 --> 00:24:20,640
Speaker 1: I wonder how long it would take, because I mean,

403
00:24:20,680 --> 00:24:23,720
Speaker 1: that's not even that long of a drive anyway. Yeah,

404
00:24:23,800 --> 00:24:27,040
Speaker 1: I agreed. Let maybe ten minutes, which I mean if

405
00:24:27,080 --> 00:24:29,160
Speaker 1: you live in Baltimore and work in d C. I'm

406
00:24:29,200 --> 00:24:33,959
Speaker 1: sure that would be extremely attractive. Yeah, that's true. Um,

407
00:24:34,000 --> 00:24:36,760
Speaker 1: I don't know about the Atlanta at Chattanooga thing. Who cares, right,

408
00:24:37,080 --> 00:24:40,440
Speaker 1: you know, people in Chattanooga be psyched, I guess because

409
00:24:40,440 --> 00:24:42,560
Speaker 1: they could get to the airport in like thirty minutes. Yeah,

410
00:24:42,600 --> 00:24:46,359
Speaker 1: I guess, not just in Chattanooga. I'll go there and

411
00:24:46,400 --> 00:24:50,000
Speaker 1: paying for gold. I saw this, um. This It was

412
00:24:50,080 --> 00:24:53,560
Speaker 1: some Discovery show video from a Discovery show too, um,

413
00:24:53,600 --> 00:24:57,600
Speaker 1: and it had our good friend Michio Kaku, and he

414
00:24:57,640 --> 00:25:02,240
Speaker 1: was talking about train, bullet train that could get you

415
00:25:02,640 --> 00:25:05,840
Speaker 1: from one side of the world to the other in

416
00:25:05,880 --> 00:25:09,399
Speaker 1: an hour, and the way that it would do that

417
00:25:09,560 --> 00:25:13,240
Speaker 1: is to go through the middle of the Earth. Basically,

418
00:25:13,640 --> 00:25:16,320
Speaker 1: you would have to create this to basically like Elon

419
00:25:16,440 --> 00:25:19,639
Speaker 1: Musk's idea, you create a tube, you evacuate all of

420
00:25:19,680 --> 00:25:23,840
Speaker 1: the air out of it so that there's no resistance whatsoever,

421
00:25:24,080 --> 00:25:26,800
Speaker 1: and you just drop in the force of gravity takes

422
00:25:26,840 --> 00:25:29,639
Speaker 1: you up to about eighteen thousand miles an hour, and

423
00:25:29,680 --> 00:25:31,360
Speaker 1: then once you make it to the center and out

424
00:25:31,400 --> 00:25:34,879
Speaker 1: the other side, your gravity starts to work against you,

425
00:25:34,960 --> 00:25:38,280
Speaker 1: so it slows you down. So within an hour you

426
00:25:38,280 --> 00:25:40,199
Speaker 1: should be able to make it from one side of

427
00:25:40,240 --> 00:25:43,560
Speaker 1: the Earth to the other. But as Dr Coku put

428
00:25:44,320 --> 00:25:47,680
Speaker 1: put it, um, it's gonna be very difficult getting through

429
00:25:47,720 --> 00:25:52,600
Speaker 1: the center of the Earth, all of all these theoretical

430
00:25:52,600 --> 00:25:54,919
Speaker 1: ideas that come up with it, like it's not even

431
00:25:54,960 --> 00:25:59,040
Speaker 1: even remotely possible. And he'd probably say, like, I was

432
00:25:59,080 --> 00:26:00,879
Speaker 1: just talking about what they ask me to talk about.

433
00:26:01,320 --> 00:26:03,360
Speaker 1: It's like, dude, I was at McDonald's one day when

434
00:26:03,359 --> 00:26:06,480
Speaker 1: I said that, I was waiting in line at McDonald's.

435
00:26:07,440 --> 00:26:10,960
Speaker 1: So what else you got? I got nothing else? Maglev? Yeah,

436
00:26:11,040 --> 00:26:12,879
Speaker 1: the Way of the Future. Yeah, we've got a we

437
00:26:12,920 --> 00:26:16,160
Speaker 1: have a standing bet. Now we will see a maglev

438
00:26:16,240 --> 00:26:18,400
Speaker 1: train in operation that we can ride on while we're

439
00:26:18,400 --> 00:26:23,400
Speaker 1: both alive. That's my bet. You say no that we will, Like,

440
00:26:23,600 --> 00:26:25,080
Speaker 1: I mean, if we went to Shanghai, we could do

441
00:26:25,119 --> 00:26:27,520
Speaker 1: it right now. So I feel like I just want

442
00:26:27,560 --> 00:26:29,399
Speaker 1: my bet well health that you're gonna pay for us

443
00:26:29,880 --> 00:26:35,320
Speaker 1: here in the United States, um, within our lifetime, which

444
00:26:35,320 --> 00:26:37,400
Speaker 1: for me is gonna be about twenty years. We're both

445
00:26:37,400 --> 00:26:40,800
Speaker 1: still healthy enough to ride it. Okay, I'll take that

446
00:26:40,800 --> 00:26:44,680
Speaker 1: bet okay. Uh. Let's see. If you guys want to

447
00:26:44,760 --> 00:26:47,119
Speaker 1: learn more about maglev, you can type that word in

448
00:26:47,200 --> 00:26:50,000
Speaker 1: the search part how stuff works dot Com. And since

449
00:26:50,080 --> 00:26:52,720
Speaker 1: I said a search part, it's time for listener mail.

450
00:26:54,640 --> 00:26:57,199
Speaker 1: That's right. This is I'm gonna call this opportunity for

451
00:26:57,280 --> 00:27:02,760
Speaker 1: students filmmaking students to get your film on Hey guys,

452
00:27:02,760 --> 00:27:06,600
Speaker 1: to work for nonprofit Antiquity Now, which is dedicated to

453
00:27:06,680 --> 00:27:10,560
Speaker 1: raising awareness of the importance of preserving our cult cultural

454
00:27:10,640 --> 00:27:15,639
Speaker 1: heritage by demonstrating how antiquities legacy influences and shapes our

455
00:27:15,680 --> 00:27:17,840
Speaker 1: lives today. Yeah, they have good stuff. We follow them

456
00:27:17,880 --> 00:27:21,119
Speaker 1: on Twitter. Oh you do nice? We do, Yes, we do.
