9
00:00:31,840 --> 00:00:34,680
Speaker 1: welcome to tech Stuff. My name is Chris Poulette. I'm

10
00:00:34,720 --> 00:00:37,320
Speaker 1: an editor here at how stuff works dot com, and

11
00:00:37,360 --> 00:00:39,680
Speaker 1: as usual, I have sitting next to me senior writer

12
00:00:39,800 --> 00:00:44,640
Speaker 1: Jonathan Strickland. Ola, Amigo, I'm wondering when you're gonna run

13
00:00:44,680 --> 00:00:47,680
Speaker 1: out of countries. Uh, there are many of them. He

14
00:00:47,800 --> 00:00:50,920
Speaker 1: watched Anomaniacs. You would know the names of all of them. Actually,

15
00:00:50,960 --> 00:00:54,400
Speaker 1: I have that c anyway speaking, and you can see

16
00:00:54,400 --> 00:00:56,520
Speaker 1: all these countries if you are looking at the Earth

17
00:00:56,560 --> 00:01:00,400
Speaker 1: from space No. Nine. That was that was a quickly

18
00:01:00,440 --> 00:01:05,679
Speaker 1: manufactured So yeah, we're gonna talk today about uh inventions

19
00:01:05,720 --> 00:01:09,480
Speaker 1: that we can we can attribute to our wonderful space

20
00:01:09,560 --> 00:01:14,080
Speaker 1: race and space exploration programs. This actually as an idea

21
00:01:14,120 --> 00:01:16,720
Speaker 1: that we got from an email we received. So I'll

22
00:01:16,800 --> 00:01:19,120
Speaker 1: let me let me start off by reading the email. Okay,

23
00:01:19,160 --> 00:01:24,119
Speaker 1: so this is from Justin in Chicago. I know how

24
00:01:24,200 --> 00:01:29,120
Speaker 1: you love to receive haikus from fans. Oh wait, wrong podcast.

25
00:01:30,160 --> 00:01:32,920
Speaker 1: I've always wondered whether people knew what they were talking

26
00:01:32,959 --> 00:01:35,639
Speaker 1: about when they credited NASA with the invention of certain

27
00:01:35,680 --> 00:01:40,320
Speaker 1: technologies velcro, m r eyes, and that delicious dehydrated ice cream,

28
00:01:40,360 --> 00:01:43,840
Speaker 1: to name a few. Is the alleged government origin for

29
00:01:44,000 --> 00:01:47,960
Speaker 1: dozens upon dozens of everyday products just a public exaggeration

30
00:01:48,040 --> 00:01:52,120
Speaker 1: or misconception Which of these are actual NASA technologies. I'm

31
00:01:52,120 --> 00:01:55,560
Speaker 1: too lazy lazy to research it myself, so I'd like

32
00:01:55,640 --> 00:01:57,760
Speaker 1: to hear you guys talk about it for fifteen or

33
00:01:57,760 --> 00:02:04,080
Speaker 1: twenty minutes instead. You got it justin excellent. Yeah. Now,

34
00:02:04,160 --> 00:02:06,720
Speaker 1: first of all, um, well let's go ahead and and

35
00:02:06,840 --> 00:02:12,280
Speaker 1: uh and crush velcrow, Well, crunchy noise. So Velcrow is

36
00:02:12,520 --> 00:02:17,280
Speaker 1: not a NASA invention. It was a Swiss invention dating

37
00:02:17,320 --> 00:02:21,359
Speaker 1: back to the nineteen forties. Yeah, that's much older than NASA, right, Yes,

38
00:02:21,480 --> 00:02:24,320
Speaker 1: NASA was not around in the nineteen fourties. No, they were,

39
00:02:24,520 --> 00:02:29,600
Speaker 1: say space was actually out there in I think I

40
00:02:29,639 --> 00:02:32,680
Speaker 1: think space first appeared on the scene somewhere right around

41
00:02:33,000 --> 00:02:36,240
Speaker 1: six o three. Um, please don't write me. I know

42
00:02:36,320 --> 00:02:39,520
Speaker 1: I'm making that up. The so so yeah, dated back

43
00:02:39,520 --> 00:02:42,160
Speaker 1: from the nineteen Fouries is a Swiss invention. Now, NASA

44
00:02:42,240 --> 00:02:45,640
Speaker 1: did use velcro in the Apollo missions. Um, and that

45
00:02:45,840 --> 00:02:49,080
Speaker 1: kind of made velcro more famous, So that might be

46
00:02:49,120 --> 00:02:52,160
Speaker 1: where people got the idea that NASA invented it. They

47
00:02:52,200 --> 00:02:54,560
Speaker 1: did not. Um. Also, let's go ahead and get the

48
00:02:54,600 --> 00:02:56,680
Speaker 1: other two big ones out of the way. They did

49
00:02:56,680 --> 00:03:02,799
Speaker 1: not invent teflon, and they did not invent tang as

50
00:03:03,240 --> 00:03:07,240
Speaker 1: the powdered sweet sweet drink. No. According to the end

51
00:03:07,360 --> 00:03:11,440
Speaker 1: the NASA website, Tang predates the Space missions by a

52
00:03:11,480 --> 00:03:15,799
Speaker 1: few years. However, astronauts do find it yummy, yes, and

53
00:03:16,120 --> 00:03:19,040
Speaker 1: NASA did use it in various kind of promotional materials,

54
00:03:19,080 --> 00:03:21,520
Speaker 1: So that'd be where you'd get that idea from. Too. Well,

55
00:03:21,520 --> 00:03:23,720
Speaker 1: there are lots of things like that that uh you know,

56
00:03:23,760 --> 00:03:26,560
Speaker 1: I mean vell Crow, NASA loves ll grow. It's it's

57
00:03:26,560 --> 00:03:31,480
Speaker 1: great environment, very useful stuff, and I'm thinking that's probably why,

58
00:03:31,800 --> 00:03:34,520
Speaker 1: you know, and Tang was still fairly new when the

59
00:03:34,520 --> 00:03:36,640
Speaker 1: astronauts were going up in the space, so you know,

60
00:03:37,000 --> 00:03:39,720
Speaker 1: it kind of makes sense that public perception might have

61
00:03:39,800 --> 00:03:43,880
Speaker 1: been that NASA picked those up and they amended him, right.

62
00:03:43,920 --> 00:03:48,000
Speaker 1: I briefly debated on arguing that UM that Nicholas the

63
00:03:48,040 --> 00:03:51,120
Speaker 1: second Infinite Oval Team, but then I realized that that

64
00:03:51,160 --> 00:03:54,080
Speaker 1: would spreading misinformation is not what we do here, just

65
00:03:54,120 --> 00:03:57,400
Speaker 1: going to get more emails. So he did not, to

66
00:03:57,480 --> 00:03:59,560
Speaker 1: my knowledge anyway, I just made that up. So if

67
00:03:59,560 --> 00:04:02,880
Speaker 1: it's is true, I was totally by chance. Moving on

68
00:04:02,920 --> 00:04:06,080
Speaker 1: to the actual inventions that NASA is responsible for, there

69
00:04:06,080 --> 00:04:08,880
Speaker 1: are many of them. Justin he asked us if there

70
00:04:08,920 --> 00:04:11,320
Speaker 1: were some if if if that was just kind of

71
00:04:11,360 --> 00:04:14,560
Speaker 1: a misconception. No, it's not a misconception. There are plenty

72
00:04:14,640 --> 00:04:18,080
Speaker 1: of inventions out there that we can credit NASA for

73
00:04:18,160 --> 00:04:20,920
Speaker 1: bringing to life. And we have an article on the

74
00:04:20,960 --> 00:04:23,800
Speaker 1: site called ten NASA inventions you might use every day,

75
00:04:23,839 --> 00:04:26,719
Speaker 1: written by our colleague Kristen Conger, who is an excellent

76
00:04:26,760 --> 00:04:30,200
Speaker 1: writer here at how stuff Works dot com and UM.

77
00:04:30,240 --> 00:04:34,040
Speaker 1: She mentions that NASA has filed more than sixty three

78
00:04:34,360 --> 00:04:38,159
Speaker 1: D patents with the US government. Uh, and not all

79
00:04:38,200 --> 00:04:41,960
Speaker 1: of those are specifically for things that can only apply

80
00:04:42,160 --> 00:04:46,480
Speaker 1: to space exploration or or space you know, uh missions.

81
00:04:46,880 --> 00:04:50,120
Speaker 1: Many of those things that that NASA has filed patents

82
00:04:50,120 --> 00:04:55,279
Speaker 1: for we now use in uh in everyday applications. Should

83
00:04:55,279 --> 00:04:57,400
Speaker 1: I should I mention one? I it sounded like you

84
00:04:57,440 --> 00:04:58,960
Speaker 1: had one on the top of your head. Well, the

85
00:04:59,040 --> 00:05:00,760
Speaker 1: very first one, she mean gins I guess I can

86
00:05:00,800 --> 00:05:02,720
Speaker 1: kind of go in descending order. We're not going to

87
00:05:02,800 --> 00:05:04,880
Speaker 1: mention all of the ones in the article because there's

88
00:05:04,920 --> 00:05:07,320
Speaker 1: some she doesn't mention that I like. Yeah, there's quite

89
00:05:07,360 --> 00:05:09,159
Speaker 1: a few that we wanted to talk about and we

90
00:05:09,160 --> 00:05:11,400
Speaker 1: didn't want to just you know, regurgitate the article. But

91
00:05:11,440 --> 00:05:14,360
Speaker 1: the first one she mentions, um, would be invisible braces.

92
00:05:15,520 --> 00:05:18,760
Speaker 1: I never had them. However, if I had, you'd never

93
00:05:18,800 --> 00:05:22,800
Speaker 1: have known it, right. Uh. They're made from translucent poly

94
00:05:22,880 --> 00:05:27,680
Speaker 1: crystalline alumina t p A and uh. The reason why

95
00:05:27,720 --> 00:05:29,760
Speaker 1: we can credit NASA for this is that they were

96
00:05:29,839 --> 00:05:34,719
Speaker 1: using this material to protect infrared antenna of heat seeking

97
00:05:34,760 --> 00:05:39,480
Speaker 1: missile trackers. Yeah, but it turns out that there was

98
00:05:39,520 --> 00:05:42,839
Speaker 1: another company called Unitech that was working on a new

99
00:05:43,120 --> 00:05:47,839
Speaker 1: kind of design for braces, and so you take the

100
00:05:47,960 --> 00:05:52,080
Speaker 1: material created by NASA essentially, but Sara Dyne was the

101
00:05:52,120 --> 00:05:55,839
Speaker 1: company that really developed it, but NASA was behind the

102
00:05:55,880 --> 00:05:59,200
Speaker 1: whole research stage. And then you take Unitech that's making

103
00:05:59,240 --> 00:06:02,200
Speaker 1: this brace the um this new form of braces, and

104
00:06:02,279 --> 00:06:04,680
Speaker 1: you apply the material to the design and you come

105
00:06:04,720 --> 00:06:08,480
Speaker 1: up with invisible braces. Wow. Yeah, So thank you NASA

106
00:06:08,560 --> 00:06:11,320
Speaker 1: for straightening out some teeth. And you know they can

107
00:06:11,400 --> 00:06:15,320
Speaker 1: chew on some missiles. Um. I guess I wasn't done

108
00:06:15,320 --> 00:06:17,800
Speaker 1: being goofy. You know my favorite on that list? What's

109
00:06:17,839 --> 00:06:22,240
Speaker 1: that memory foam? Memory foam? That some good stuff. Man.

110
00:06:22,360 --> 00:06:24,400
Speaker 1: If you've ever put your hand on a memory foam

111
00:06:24,400 --> 00:06:26,800
Speaker 1: mattress and watched your fingerprints stay there after you pulled

112
00:06:26,920 --> 00:06:31,680
Speaker 1: your hand away, thank an astronaut or probably a NASA researcher. Yeah.

113
00:06:31,680 --> 00:06:35,320
Speaker 1: The whole temper pedic mattresses, that all comes from the

114
00:06:35,320 --> 00:06:37,640
Speaker 1: whole NASA research. Yeah. I'd like to be on one

115
00:06:37,720 --> 00:06:40,240
Speaker 1: right now. Me too. I was just thinking that. I'm like,

116
00:06:40,320 --> 00:06:42,360
Speaker 1: why did you go with that? Yeah, I'm sorry, I've

117
00:06:42,360 --> 00:06:44,599
Speaker 1: been thinking. This is the end of a very long day. People.

118
00:06:45,520 --> 00:06:48,880
Speaker 1: We have recorded two other podcasts today. I hate to

119
00:06:48,960 --> 00:06:52,719
Speaker 1: break the veil here, but uh yeah, So the idea

120
00:06:52,720 --> 00:06:55,719
Speaker 1: of laying down on foam that develops you and comforts

121
00:06:55,720 --> 00:06:58,960
Speaker 1: you since really really nice. We need a we need

122
00:06:59,000 --> 00:07:04,080
Speaker 1: a house. Stuff works dot come like nap room anyway, right,

123
00:07:04,080 --> 00:07:06,960
Speaker 1: making a note, Ok, moving on, so yes, yes, the

124
00:07:07,000 --> 00:07:12,080
Speaker 1: memory foam that also comes from NASA research. Um oh

125
00:07:12,160 --> 00:07:17,040
Speaker 1: she Kristen also mentions shoe in souls, which we can

126
00:07:17,080 --> 00:07:21,000
Speaker 1: thank Moon Boots for. Yeah, we're talking about like the

127
00:07:21,120 --> 00:07:24,960
Speaker 1: insoles and shoes that are used to help your you know,

128
00:07:25,200 --> 00:07:27,160
Speaker 1: give you a little bit of a boost with athletic

129
00:07:27,200 --> 00:07:32,200
Speaker 1: shoes and and make it breathable and comfortable like a

130
00:07:32,280 --> 00:07:37,680
Speaker 1: felon like Magellan. We should get paid for by them,

131
00:07:37,880 --> 00:07:41,960
Speaker 1: I mean we don't anyway. So again we're talking about

132
00:07:42,280 --> 00:07:44,559
Speaker 1: you know, it seems kind of silly that you're thinking like, oh,

133
00:07:44,600 --> 00:07:47,240
Speaker 1: just chee in souls, but no, seriously, there's this. The

134
00:07:47,320 --> 00:07:49,720
Speaker 1: technology for these cushy shoe and soules that give you

135
00:07:49,760 --> 00:07:53,400
Speaker 1: a lot more support came out of NASA research. Well, honestly,

136
00:07:53,440 --> 00:07:56,120
Speaker 1: if you if you think about some of the other stuff,

137
00:07:56,160 --> 00:07:59,320
Speaker 1: like invisible braces, well we could use visible braces, but

138
00:07:59,440 --> 00:08:01,720
Speaker 1: it does add something and adds a quality of life

139
00:08:01,760 --> 00:08:04,840
Speaker 1: and not everything is um you know, it has to

140
00:08:04,880 --> 00:08:07,920
Speaker 1: be some kind of groundbreaking new science, you know, for

141
00:08:08,000 --> 00:08:09,840
Speaker 1: it to be useful and functional for us. So it's

142
00:08:09,920 --> 00:08:12,320
Speaker 1: you know, these are good things. Now, there are a

143
00:08:12,320 --> 00:08:17,680
Speaker 1: lot of things that are different between Chris and yours, truly,

144
00:08:18,120 --> 00:08:19,520
Speaker 1: you know, there are a lot of things that you know,

145
00:08:19,640 --> 00:08:21,320
Speaker 1: we don't. There are a lot of things that we

146
00:08:21,320 --> 00:08:23,960
Speaker 1: we feel very differently about. But um, we also share

147
00:08:24,000 --> 00:08:27,640
Speaker 1: a few similarities. One of those that we both wear

148
00:08:27,840 --> 00:08:34,040
Speaker 1: spectacles glasses. Do you have scratch resistant lenses? Um? I

149
00:08:34,120 --> 00:08:37,160
Speaker 1: certainly hope so, because my youngest daughter likes to grab

150
00:08:37,200 --> 00:08:38,600
Speaker 1: them and rip them off my face and try to

151
00:08:38,640 --> 00:08:41,559
Speaker 1: eat them nice. Um, they have not scratched yet. My

152
00:08:41,640 --> 00:08:44,439
Speaker 1: jackerosal terriers like to do the same thing. Perhaps they

153
00:08:44,480 --> 00:08:48,000
Speaker 1: all get together while we're at work and plot things

154
00:08:48,000 --> 00:08:51,520
Speaker 1: to do to us. But yes, scratch resistant lenses, that's

155
00:08:51,520 --> 00:08:54,600
Speaker 1: another thing we can thank NASA for now. NASA the

156
00:08:54,640 --> 00:08:58,360
Speaker 1: reason they developed this material the special coding to help

157
00:08:58,360 --> 00:09:03,160
Speaker 1: protect equipment and face because I mean it's very sensitive equipment. Uh,

158
00:09:03,200 --> 00:09:05,760
Speaker 1: and there are particles out in space that are floating

159
00:09:05,800 --> 00:09:07,920
Speaker 1: around and you could come into contact with it, and

160
00:09:07,960 --> 00:09:10,880
Speaker 1: you definitely don't want something scratching up your your equipment

161
00:09:10,880 --> 00:09:12,640
Speaker 1: while you're out in space, especially if it's going to

162
00:09:12,720 --> 00:09:16,240
Speaker 1: end up, you know, endangering the people on the mission,

163
00:09:16,559 --> 00:09:21,840
Speaker 1: much less endangering multibillion dollar equipment that's up there. So

164
00:09:22,640 --> 00:09:26,640
Speaker 1: this material they've created, the special coding they you know,

165
00:09:27,080 --> 00:09:30,880
Speaker 1: scientists adapted it to create the scratch resistant coding they

166
00:09:30,920 --> 00:09:34,320
Speaker 1: put on lenses. So if you have glasses that have

167
00:09:34,400 --> 00:09:37,320
Speaker 1: this coating on them, you can thank NASA for it. Definitely,

168
00:09:37,400 --> 00:09:40,800
Speaker 1: thank you, NASA, Thank you very much. Otherwise I couldn't see.

169
00:09:42,000 --> 00:09:45,280
Speaker 1: So do you want to diverge from the well, I

170
00:09:45,280 --> 00:09:48,959
Speaker 1: think I have one. I think I have to tell

171
00:09:49,000 --> 00:09:50,560
Speaker 1: me which one is you like? So the other one

172
00:09:50,600 --> 00:09:53,600
Speaker 1: I was thinking about talking about long distance telecommunications, that's

173
00:09:53,600 --> 00:09:56,080
Speaker 1: a gimme. Yeah, And the satellite dish was when I

174
00:09:56,080 --> 00:09:57,480
Speaker 1: was going to bring up. But they're they're sort of

175
00:09:57,520 --> 00:10:03,440
Speaker 1: intertwined because they use satellite technology to communicate, right, and uh, yeah,

176
00:10:03,480 --> 00:10:06,880
Speaker 1: we're talking about the you know, the NASA had to

177
00:10:06,880 --> 00:10:12,280
Speaker 1: create telecommunication devices that would be able to span enormous distances.

178
00:10:12,520 --> 00:10:15,439
Speaker 1: Because you're talking about trying to maintain contact with people

179
00:10:15,640 --> 00:10:19,840
Speaker 1: in outer space. It's hard to get further away than that. Yes,

180
00:10:19,880 --> 00:10:25,200
Speaker 1: otherwise Tom Hanks would be stranded in space right now. Yeah,

181
00:10:25,240 --> 00:10:27,400
Speaker 1: but then we would have been spared that horrible haircut

182
00:10:27,520 --> 00:10:32,800
Speaker 1: from the what was it the Da Vinci Code. But

183
00:10:32,840 --> 00:10:35,240
Speaker 1: anyone don't know whether to thank them or curse them.

184
00:10:36,120 --> 00:10:40,520
Speaker 1: I'm keeping him in mind. Of course that was a movie,

185
00:10:39,520 --> 00:10:43,000
Speaker 1: right exactly. Of course, again, they would have been in

186
00:10:43,120 --> 00:10:46,040
Speaker 1: bad shape if they hadn't been able to communicate with Houston,

187
00:10:46,120 --> 00:10:49,320
Speaker 1: and we're very thankful that they were. But yes, the

188
00:10:49,400 --> 00:10:52,000
Speaker 1: same technology that they developed in order to communicate with

189
00:10:52,040 --> 00:10:55,640
Speaker 1: astronauts was then of course used to for you know,

190
00:10:55,679 --> 00:11:00,200
Speaker 1: broadcast technology, for telecommunications technology, uh, you know, with out

191
00:11:00,280 --> 00:11:04,280
Speaker 1: Without NASA, I'm sure we would have gone down those

192
00:11:04,360 --> 00:11:08,000
Speaker 1: roads eventually anyway, but probably not with the same kind

193
00:11:08,040 --> 00:11:12,839
Speaker 1: of alacrity that we did thanks to NASA. With the alacrity. Yeah,

194
00:11:12,880 --> 00:11:14,520
Speaker 1: I like a lot of throw that in there. And

195
00:11:14,559 --> 00:11:16,600
Speaker 1: the other one that I thought I mentioned from the article,

196
00:11:16,800 --> 00:11:20,200
Speaker 1: uh was water filters. Yeah, which again you're talking about

197
00:11:20,440 --> 00:11:22,440
Speaker 1: if you're gonna send people out up in space, you

198
00:11:22,480 --> 00:11:24,440
Speaker 1: may need a way to filter some water so that

199
00:11:24,480 --> 00:11:26,800
Speaker 1: they can have something to drink or something else that

200
00:11:26,840 --> 00:11:29,800
Speaker 1: you have to filter some sort of liquid so that

201
00:11:29,840 --> 00:11:34,720
Speaker 1: you would have drinkable water. It doesn't take a whiz

202
00:11:34,800 --> 00:11:39,080
Speaker 1: to know what we're talking about. So um so again

203
00:11:39,679 --> 00:11:42,240
Speaker 1: water filters, the same sort of water filters we use

204
00:11:42,320 --> 00:11:44,959
Speaker 1: for our tap water. We can thank NASA for creating

205
00:11:44,960 --> 00:11:47,439
Speaker 1: that kind of technology, and I thank them for that

206
00:11:47,720 --> 00:11:50,720
Speaker 1: horrible joke. You can blame them for it if you like.

207
00:11:50,960 --> 00:11:53,600
Speaker 1: All Right, So now we can go and talk about

208
00:11:53,640 --> 00:11:56,920
Speaker 1: some of the stuff that is not on the in

209
00:11:56,960 --> 00:11:59,040
Speaker 1: the actual article, and then there are more on in

210
00:11:59,080 --> 00:12:02,320
Speaker 1: the article if you want check it out. Yeah, speaking

211
00:12:02,360 --> 00:12:07,720
Speaker 1: of lenses, they helped invent some sunglass technology that works

212
00:12:07,760 --> 00:12:12,240
Speaker 1: with polarization and keeping out frequencies of light that may

213
00:12:12,240 --> 00:12:14,559
Speaker 1: be harmful to your eyes. Well, that makes sense because

214
00:12:14,559 --> 00:12:16,200
Speaker 1: I mean, you know, you're out in space. You don't

215
00:12:16,240 --> 00:12:17,920
Speaker 1: have that kind of you don't have the benefit of

216
00:12:17,960 --> 00:12:21,240
Speaker 1: the Earth's atmosphere to to filter that out. That's true,

217
00:12:21,240 --> 00:12:23,160
Speaker 1: and from what i've from what I read, it was

218
00:12:23,200 --> 00:12:26,120
Speaker 1: also because they were working on welding and the incredibly

219
00:12:26,160 --> 00:12:29,000
Speaker 1: bright light from you know, certain kinds of welding can

220
00:12:29,040 --> 00:12:30,800
Speaker 1: do serious damage to your eyes, and they needed an

221
00:12:30,800 --> 00:12:35,079
Speaker 1: inability to you know, protect the eyes of the astronauts.

222
00:12:35,080 --> 00:12:37,680
Speaker 1: But with the blast shield down, I can't see anything.

223
00:12:37,679 --> 00:12:39,840
Speaker 1: How am I supposed to be able to fight? Okay,

224
00:12:39,880 --> 00:12:43,400
Speaker 1: so I'm gonna have to pick another one. Huh um,

225
00:12:43,559 --> 00:12:46,880
Speaker 1: thermal gloves and boots. Oh yeah, okay. I mean it's

226
00:12:46,920 --> 00:12:51,680
Speaker 1: cold in space, very cold, very cold in space, thank you,

227
00:12:51,800 --> 00:12:56,880
Speaker 1: con So you know they the astronauts need protection. I

228
00:12:56,920 --> 00:12:59,680
Speaker 1: didn't mean to do that, I swear, um, but that

229
00:12:59,720 --> 00:13:01,880
Speaker 1: trains slates. You know. It's also very cold in certain

230
00:13:01,880 --> 00:13:05,120
Speaker 1: parts of the Earth, and you know, applying that technology

231
00:13:05,320 --> 00:13:08,200
Speaker 1: white weight technology and not so much a matter in space,

232
00:13:08,240 --> 00:13:10,480
Speaker 1: but when you're you know, dressed in that stuff to

233
00:13:10,520 --> 00:13:13,839
Speaker 1: get into the cockpit before you blast off, it's kind

234
00:13:13,840 --> 00:13:17,440
Speaker 1: of heavy. Those early space suits were pretty gargagein yeah,

235
00:13:18,160 --> 00:13:21,360
Speaker 1: you know, they were not smelled no, but you know,

236
00:13:21,400 --> 00:13:24,400
Speaker 1: as a result, we have lighter and thinner uh and

237
00:13:24,679 --> 00:13:29,640
Speaker 1: warmer fibers. And on a similar note, uh, we've had

238
00:13:29,679 --> 00:13:33,800
Speaker 1: the same sort of material coming handy for things like

239
00:13:33,840 --> 00:13:37,560
Speaker 1: a firefighting equipment. So we're talking about like the suits

240
00:13:37,559 --> 00:13:40,480
Speaker 1: that that firefighters wear, that our fire resistant fabrics, I

241
00:13:40,520 --> 00:13:43,200
Speaker 1: mean the a lot of that fabric was originally developed

242
00:13:43,320 --> 00:13:46,480
Speaker 1: um to be used in space suits, which have to

243
00:13:46,679 --> 00:13:51,640
Speaker 1: not just be able to withstand intense uh well the

244
00:13:51,640 --> 00:13:57,280
Speaker 1: intense heat and intense cold. So um. Yeah again, NASA

245
00:13:57,480 --> 00:14:00,160
Speaker 1: came up with the technology and that's that's on the

246
00:14:00,160 --> 00:14:04,200
Speaker 1: ways we use it today. Um. Apparently they're also responsible

247
00:14:04,240 --> 00:14:09,120
Speaker 1: in in some way for redundant flashlight technology. UM. Well,

248
00:14:09,160 --> 00:14:11,240
Speaker 1: you think about it. You may need a flashlight and

249
00:14:11,280 --> 00:14:15,280
Speaker 1: then you might need another one. The thing is, uh,

250
00:14:15,400 --> 00:14:17,679
Speaker 1: if you have one of those flashlights that is supposed

251
00:14:17,679 --> 00:14:20,640
Speaker 1: to be have multiple sources of power in case, uh

252
00:14:20,680 --> 00:14:22,960
Speaker 1: the electricity goes out in one of the batteries isn't charged,

253
00:14:23,080 --> 00:14:26,280
Speaker 1: or you're in a fire, um, and you need a flashlight. Well,

254
00:14:26,480 --> 00:14:28,720
Speaker 1: they you know, one of the projects that came out

255
00:14:28,720 --> 00:14:32,440
Speaker 1: of NASA was you know, the multiple backup power systems

256
00:14:32,440 --> 00:14:36,600
Speaker 1: for flashlights built in, which is again not exactly glamorous,

257
00:14:36,840 --> 00:14:40,800
Speaker 1: but very useful. Nice And of course you know justin

258
00:14:40,840 --> 00:14:43,440
Speaker 1: mentioned MR eyes which the m R e s and

259
00:14:43,480 --> 00:14:46,560
Speaker 1: cat scans we can we can trace that back to NASA.

260
00:14:47,040 --> 00:14:49,520
Speaker 1: Do you have information on those? That was one of

261
00:14:49,520 --> 00:14:53,880
Speaker 1: the ones that I read may have been amiss. Go ahead.

262
00:14:54,040 --> 00:14:57,240
Speaker 1: I have heard they have done work with medical um

263
00:14:57,360 --> 00:14:59,720
Speaker 1: imaging technology and I think that's part of it too.

264
00:14:59,800 --> 00:15:03,400
Speaker 1: But because uh, there's a NASA website that goes into

265
00:15:03,480 --> 00:15:06,800
Speaker 1: all the different things, and the thing is, I think

266
00:15:06,880 --> 00:15:11,320
Speaker 1: what happens is uh NASA says, oh my gosh, that's brilliant.

267
00:15:11,320 --> 00:15:13,280
Speaker 1: We absolutely need this in the space program. And it

268
00:15:13,320 --> 00:15:16,120
Speaker 1: gets so well known and so associated with the space

269
00:15:16,120 --> 00:15:18,440
Speaker 1: program that people assume that, you know, well, those geniuses

270
00:15:18,440 --> 00:15:20,160
Speaker 1: and NASA, I've done it again, when in fact it's

271
00:15:20,200 --> 00:15:23,400
Speaker 1: genius that NASA is working with. Sure, sure you know,

272
00:15:23,440 --> 00:15:28,080
Speaker 1: I think I think yeah. And in that case, I

273
00:15:28,120 --> 00:15:30,520
Speaker 1: think they were using that technology in order to to

274
00:15:30,680 --> 00:15:35,160
Speaker 1: look for vulnerabilities within the various UH equipment they were

275
00:15:35,240 --> 00:15:37,040
Speaker 1: using to make sure there weren't any cracks or anything

276
00:15:37,080 --> 00:15:39,600
Speaker 1: like that. And you absolutely need to check the integrity

277
00:15:39,680 --> 00:15:41,400
Speaker 1: of your equipment if you're going out in the space,

278
00:15:41,440 --> 00:15:45,040
Speaker 1: as we have all found out unfortunately. Um, do you

279
00:15:45,040 --> 00:15:48,240
Speaker 1: have another one? I have a favorite one, don't you know?

280
00:15:48,280 --> 00:15:50,440
Speaker 1: If I should go ahead and drop your favorite on? Man,

281
00:15:50,440 --> 00:15:54,560
Speaker 1: I'm looking through my list space pens. The space pen

282
00:15:54,720 --> 00:15:57,880
Speaker 1: is awesome. I know, I know. It's the space pen

283
00:15:57,960 --> 00:16:02,520
Speaker 1: for the uninitiative and initiated uninitiated. There we go. Um

284
00:16:02,760 --> 00:16:06,320
Speaker 1: is a pressurized ballpoint pen. He may be saying, Yeah,

285
00:16:06,480 --> 00:16:09,960
Speaker 1: that's really exciting there dude, Well, no, okay, it's not.

286
00:16:10,280 --> 00:16:13,440
Speaker 1: But you can write in all kinds of different environments

287
00:16:13,520 --> 00:16:15,560
Speaker 1: using the space pen. And it's very handy if you

288
00:16:15,640 --> 00:16:18,080
Speaker 1: have one and only one pen to use, and keeping

289
00:16:18,120 --> 00:16:19,720
Speaker 1: in mind, this is not the kind of environment where

290
00:16:19,720 --> 00:16:22,520
Speaker 1: you're going to take your favorite fountain pen and have

291
00:16:22,640 --> 00:16:28,560
Speaker 1: little drops of ink floating all over the capsule. So well,

292
00:16:28,560 --> 00:16:31,920
Speaker 1: you would do it just for fun. Uh you know, anyway,

293
00:16:32,120 --> 00:16:35,240
Speaker 1: other other ballpoint pens wouldn't write in space a fountain

294
00:16:35,240 --> 00:16:37,880
Speaker 1: pen again, blobs of ink. So what do you do?

295
00:16:38,040 --> 00:16:40,760
Speaker 1: You pressurize a ballpoint pen and you can still buy it.

296
00:16:40,920 --> 00:16:42,920
Speaker 1: It's it's very widely available. You can get it from

297
00:16:42,920 --> 00:16:44,960
Speaker 1: pen companies. You can't even get it from office supply stores.

298
00:16:45,160 --> 00:16:47,120
Speaker 1: It's a little bit more expensive than a regular pen,

299
00:16:47,280 --> 00:16:50,280
Speaker 1: but you know, it can rune in virtually any environment.

300
00:16:50,440 --> 00:16:54,160
Speaker 1: So kind of nice that and I like pens. How

301
00:16:54,160 --> 00:16:57,360
Speaker 1: about joysticks? Oh yeah, you're gonna you're gonna argue with

302
00:16:57,400 --> 00:16:59,480
Speaker 1: me with joysticks. Well, you know what do they used

303
00:16:59,520 --> 00:17:03,960
Speaker 1: to fly those planes before NASA? Yeah? I saw that too.

304
00:17:04,000 --> 00:17:06,200
Speaker 1: I saw that on a NASA website. Going, wait a minute,

305
00:17:06,200 --> 00:17:08,199
Speaker 1: that that seems well, it says a little different. I

306
00:17:08,200 --> 00:17:10,440
Speaker 1: mean the joy sticks they're talking about are probably are

307
00:17:10,480 --> 00:17:14,239
Speaker 1: more along the lines of the ones they're using for UM. Uh,

308
00:17:14,320 --> 00:17:17,560
Speaker 1: you know it's it's almost the multi button video game style. Yeah,

309
00:17:17,720 --> 00:17:19,159
Speaker 1: you're talking about you know, that's the same sort of

310
00:17:19,160 --> 00:17:21,320
Speaker 1: stuff that you see in video games now. Really kind

311
00:17:21,320 --> 00:17:27,240
Speaker 1: of Trent goes back to the NASA uses for various vehicles. UM.

312
00:17:27,280 --> 00:17:28,800
Speaker 1: You know, you think about it. When you're in these

313
00:17:28,840 --> 00:17:32,639
Speaker 1: space suits. Uh, you've got very limited mobility, so you

314
00:17:32,720 --> 00:17:36,120
Speaker 1: have to have controls that are easy to grip and

315
00:17:36,320 --> 00:17:39,640
Speaker 1: use when you're you know, otherwise a little encumbered, so

316
00:17:39,800 --> 00:17:42,000
Speaker 1: you may not be able to use the same sort

317
00:17:42,040 --> 00:17:45,000
Speaker 1: of control devices that you would for other kinds of vehicles,

318
00:17:45,000 --> 00:17:49,240
Speaker 1: like a steering wheel. Um. You know. One of the

319
00:17:49,280 --> 00:17:51,760
Speaker 1: other things I discovered as I was going through my

320
00:17:51,800 --> 00:17:54,560
Speaker 1: research for this podcast was, UM, I learned about the

321
00:17:54,920 --> 00:17:56,760
Speaker 1: group that I didn't know about before, which is the

322
00:17:56,920 --> 00:18:00,560
Speaker 1: NASA Inventions and Contributions Board. UM. They've actually giving out

323
00:18:00,560 --> 00:18:03,520
Speaker 1: more than nine thousand awards according to their website, for

324
00:18:03,560 --> 00:18:06,439
Speaker 1: different technologies related to the Space program. And it can

325
00:18:06,480 --> 00:18:09,320
Speaker 1: be from NASA, from other government agencies or you know,

326
00:18:09,880 --> 00:18:14,400
Speaker 1: even public industry or or academic environments. UM. They give

327
00:18:14,400 --> 00:18:16,119
Speaker 1: away awards that they can't be any more than a

328
00:18:16,160 --> 00:18:19,080
Speaker 1: hundred thousand dollars unless they talk about it with Congress first.

329
00:18:19,640 --> 00:18:21,520
Speaker 1: I had to get Congress, is okay, So it's like

330
00:18:21,560 --> 00:18:25,760
Speaker 1: getting permission from Dad before you can you know, right right,

331
00:18:25,800 --> 00:18:27,600
Speaker 1: and actually you can. You can learn about a lot

332
00:18:27,640 --> 00:18:30,280
Speaker 1: of the technologies that are going around that NASA came

333
00:18:30,320 --> 00:18:34,240
Speaker 1: up with. There's a magazine that they offer, uh called Spinoff. UM.

334
00:18:34,280 --> 00:18:37,760
Speaker 1: It's available in print. You can't buy a subscription to it. UM.

335
00:18:37,800 --> 00:18:39,560
Speaker 1: It's a little you know, you have to be in

336
00:18:39,720 --> 00:18:41,919
Speaker 1: certain groups. I mean, it is available to the public,

337
00:18:42,000 --> 00:18:45,280
Speaker 1: but uh, you know, members of Congress, the NASA community.

338
00:18:45,400 --> 00:18:46,920
Speaker 1: It's it's not the kind of thing that I would

339
00:18:46,960 --> 00:18:48,760
Speaker 1: imagine most people want to read. But you can sign

340
00:18:48,880 --> 00:18:52,720
Speaker 1: up for a free trial issue, which um, which I said,

341
00:18:53,080 --> 00:18:56,800
Speaker 1: which you did because you know, I'm interested in this stuff. UM.

342
00:18:56,840 --> 00:18:59,639
Speaker 1: And you know there are other tools too that people

343
00:18:59,680 --> 00:19:04,280
Speaker 1: give NASA credit for, um, such as barcodes um and

344
00:19:04,440 --> 00:19:08,160
Speaker 1: quartz clocks. So you know these things some of them

345
00:19:08,160 --> 00:19:11,600
Speaker 1: and you know are used by NASA in different forms,

346
00:19:11,920 --> 00:19:13,439
Speaker 1: but you know the ones that you see on the

347
00:19:13,440 --> 00:19:17,440
Speaker 1: package at your local grocery store, you know, not really Yeah,

348
00:19:17,760 --> 00:19:20,320
Speaker 1: just because it says space age does not necessarily mean

349
00:19:20,320 --> 00:19:23,640
Speaker 1: that it came from NASA, although I could. I think

350
00:19:23,640 --> 00:19:27,520
Speaker 1: I know what my favorite, my favorite invention based off

351
00:19:27,520 --> 00:19:32,080
Speaker 1: of NASA's research really is. And I'm talking about the

352
00:19:32,080 --> 00:19:36,919
Speaker 1: the Speedo suit swimming So okay, because all right, so

353
00:19:36,960 --> 00:19:39,959
Speaker 1: you've got NASA, You've got this, uh, this enormous organization

354
00:19:40,000 --> 00:19:42,679
Speaker 1: that I don't think there's another organization out there in

355
00:19:42,680 --> 00:19:46,240
Speaker 1: the world that knows more about friction than NASA would.

356
00:19:47,760 --> 00:19:50,680
Speaker 1: They've got to be at least among the top elite,

357
00:19:50,680 --> 00:19:54,359
Speaker 1: top three, top three, easy, ye. So yeah, So Speedo

358
00:19:54,480 --> 00:19:56,760
Speaker 1: goes up to NASA and says, hey, you know so

359
00:19:56,840 --> 00:19:59,720
Speaker 1: much about friction, what's the best way to reduce it

360
00:19:59,840 --> 00:20:02,600
Speaker 1: so that we can create a product that will move

361
00:20:02,680 --> 00:20:06,080
Speaker 1: through the water effortlessly. Oh so you're not talking about

362
00:20:06,240 --> 00:20:10,600
Speaker 1: the standard issue Speedo. You're talking about that Superla swimsuit

363
00:20:10,680 --> 00:20:15,800
Speaker 1: reduces drag, breaks records, NASA spinoff. Yes, yes, that that

364
00:20:15,960 --> 00:20:20,560
Speaker 1: Speedo and um and so according to NASA, the resulting

365
00:20:20,600 --> 00:20:25,360
Speaker 1: suit reduces skin friction drag twenty more than the previous

366
00:20:25,440 --> 00:20:30,000
Speaker 1: Speedo racing suit. You won't see me wearing one of

367
00:20:30,040 --> 00:20:33,760
Speaker 1: these at the local pool because there are laws against

368
00:20:33,760 --> 00:20:37,680
Speaker 1: that kind of thing. And thank the legislators who passed them. Yes,

369
00:20:38,800 --> 00:20:41,159
Speaker 1: so I'm done. Oh you know there was there was

370
00:20:41,200 --> 00:20:44,440
Speaker 1: one that neither of us mentioned that that it did

371
00:20:44,480 --> 00:20:47,359
Speaker 1: come in the email. Oh yeah yeah, freeze dried ice cream.

372
00:20:47,480 --> 00:20:51,360
Speaker 1: Freeze dried. They absolutely did have something to do with that. Yeah,

373
00:20:51,440 --> 00:20:53,800
Speaker 1: you can blame them, but yeah, I mean they need

374
00:20:53,840 --> 00:20:56,480
Speaker 1: freeze dried food. There's not there's not a fridge on

375
00:20:56,520 --> 00:20:58,840
Speaker 1: the Space Shuttle. But not dippin' dots. They didn't do

376
00:20:58,880 --> 00:21:00,800
Speaker 1: the No, I don't think they did dipping outs, but

377
00:21:00,840 --> 00:21:03,359
Speaker 1: there are no sense why would you have dipping dots

378
00:21:03,400 --> 00:21:06,920
Speaker 1: floating around the space cabin? You would, well, I mean

379
00:21:06,960 --> 00:21:10,080
Speaker 1: I would, but that's because i'm you know, very Homer

380
00:21:10,119 --> 00:21:15,560
Speaker 1: Simpson asked, as far as my astronaut training goes, Yeah,

381
00:21:15,560 --> 00:21:18,200
Speaker 1: I don't. I mean, they're they're tons more. But those

382
00:21:18,240 --> 00:21:20,440
Speaker 1: are just some of the more fun ones to talk about,

383
00:21:20,640 --> 00:21:24,440
Speaker 1: right right, And like we said, patents actually more than

384
00:21:24,480 --> 00:21:27,240
Speaker 1: that now. But um, yeah, it's a lot of rebound

385
00:21:27,320 --> 00:21:29,760
Speaker 1: to have. Yeah, you're bound to have some some applications

386
00:21:29,800 --> 00:21:32,800
Speaker 1: that go beyond just the space race. So justin there

387
00:21:32,840 --> 00:21:36,879
Speaker 1: are plenty of inventions out there that meet your strict criteria,

388
00:21:37,040 --> 00:21:41,600
Speaker 1: just not all the ones that you mentioned. Now, usually

389
00:21:41,640 --> 00:21:43,359
Speaker 1: this would be the part where I would say that

390
00:21:43,400 --> 00:21:45,639
Speaker 1: we have listener mail, and Chris would hide under the

391
00:21:45,680 --> 00:21:48,040
Speaker 1: table because the alarm would go off. But we I

392
00:21:48,080 --> 00:21:50,680
Speaker 1: don't have listener mail for this particular episode. And this

393
00:21:50,760 --> 00:21:52,920
Speaker 1: is this is why it's not the legislators again to

394
00:21:53,000 --> 00:21:54,800
Speaker 1: do it, because I will, I will go down and

395
00:21:54,880 --> 00:21:57,720
Speaker 1: kiss their boots. No, I actually do have listener mail.

396
00:21:57,880 --> 00:22:00,880
Speaker 1: But the listener mail I have comes in the form

397
00:22:00,880 --> 00:22:04,000
Speaker 1: of questions, and there are several of them. And we thought,

398
00:22:04,200 --> 00:22:06,399
Speaker 1: rather than throw in a listener mail at the end

399
00:22:06,400 --> 00:22:08,480
Speaker 1: of an episode and try and answer the question at

400
00:22:08,480 --> 00:22:11,280
Speaker 1: the very end of something that's totally unrelated, we're gonna

401
00:22:11,280 --> 00:22:14,880
Speaker 1: try and do an episode that's really just questions from

402
00:22:14,960 --> 00:22:18,240
Speaker 1: listeners and we're going to answer them. And we've got

403
00:22:18,240 --> 00:22:21,000
Speaker 1: several stored up already. So we'll be trying that in

404
00:22:21,040 --> 00:22:24,000
Speaker 1: the very near future and hopefully it'll be a big success.

405
00:22:24,040 --> 00:22:26,439
Speaker 1: And if it is, then I certainly hope people will

406
00:22:26,480 --> 00:22:29,040
Speaker 1: continue to write questions in because it makes it a

407
00:22:29,040 --> 00:22:31,879
Speaker 1: lot easier when Chris and I sit down and say, so,

408
00:22:31,920 --> 00:22:34,600
Speaker 1: what do you want to talk about? Yeah, So it's

409
00:22:34,600 --> 00:22:37,280
Speaker 1: a lot easier when you just put listener mail jamboree,

410
00:22:37,280 --> 00:22:39,600
Speaker 1: which is exactly what we're calling it because I just

411
00:22:39,840 --> 00:22:41,919
Speaker 1: came up with it, So listener mail jamboree in the

412
00:22:41,920 --> 00:22:44,200
Speaker 1: near future listen for it now. If you want to

Speaker 1: we will talk to you again really soon for more

424
00:23:16,480 --> 00:23:18,760
