00:00:00,320 --> 00:00:02,880
Speaker 1: Brought to you by the reinvented two thousand twelve camera.

2
00:00:03,240 --> 00:00:08,840
Speaker 1: It's ready. Are you get in touch with technology? With

3
00:00:08,920 --> 00:00:12,240
Speaker 1: tech stuff from how stuff works dot Com, brought to

4
00:00:12,280 --> 00:00:19,640
Speaker 1: you by HP Live wirelessly, print Wirelessly. Hi there, my

5
00:00:19,720 --> 00:00:21,480
Speaker 1: name is Chris Pollett. I'm an editor here at How

6
00:00:21,480 --> 00:00:24,080
Speaker 1: Stuff Works. Welcome to the podcast today. I have with

7
00:00:24,160 --> 00:00:27,240
Speaker 1: me writer Jonathan Strickland. Hey there, we're gonna talk about

8
00:00:27,280 --> 00:00:30,680
Speaker 1: how it's not easy being green, or it could be

9
00:00:30,720 --> 00:00:33,360
Speaker 1: easy being green. I mean, we do live in the

10
00:00:33,600 --> 00:00:38,000
Speaker 1: uh one century, the era of the paperless office, right, Yeah,

11
00:00:38,120 --> 00:00:42,720
Speaker 1: you don't see paper any where. I'm still waiting for

12
00:00:42,760 --> 00:00:45,680
Speaker 1: that paperless office. I don't know about you. Um. Before

13
00:00:45,960 --> 00:00:50,200
Speaker 1: before my tenure here at How Stuff Works, I lived

14
00:00:50,360 --> 00:00:53,840
Speaker 1: the life of a of a lowly worker in a

15
00:00:53,840 --> 00:00:57,279
Speaker 1: consulting firm and uh and I won't name names. I'm

16
00:00:57,280 --> 00:00:59,240
Speaker 1: not going to name where I worked or anything like that,

17
00:00:59,280 --> 00:01:02,040
Speaker 1: but I will say there were people who were notorious

18
00:01:02,080 --> 00:01:08,240
Speaker 1: for uh having their assistance retrieve emails, print them to paper,

19
00:01:08,720 --> 00:01:12,680
Speaker 1: and then hand them over, thus negating any use for

20
00:01:12,760 --> 00:01:16,520
Speaker 1: email whatsoever in my eyes. Actually, one of my big

21
00:01:16,520 --> 00:01:18,840
Speaker 1: pet peeves is walking over to the printer and this

22
00:01:18,880 --> 00:01:21,840
Speaker 1: has happened in many places I've worked, uh, walking over

23
00:01:21,880 --> 00:01:24,120
Speaker 1: the printer, picking up my print job and looking down

24
00:01:24,160 --> 00:01:26,720
Speaker 1: to see a stack of paper about the size of

25
00:01:26,760 --> 00:01:29,480
Speaker 1: a pack of paper sitting there for old print jobs

26
00:01:29,480 --> 00:01:31,920
Speaker 1: that people have never picked up. And I'm sure I

27
00:01:31,920 --> 00:01:34,200
Speaker 1: probably have contributed to that stack from time to time.

28
00:01:34,240 --> 00:01:36,520
Speaker 1: But sure, Yeah, you send something to a group printer

29
00:01:36,560 --> 00:01:38,440
Speaker 1: and then you get distracted, and then you forget that

30
00:01:38,480 --> 00:01:40,039
Speaker 1: it's just sitting there, and then you realize you never

31
00:01:40,080 --> 00:01:42,920
Speaker 1: really needed it in the first place. Exactly. So there's

32
00:01:42,920 --> 00:01:46,520
Speaker 1: all there's a human element to to printing that obviously

33
00:01:46,560 --> 00:01:50,480
Speaker 1: we could adjust to make things better, but that's not

34
00:01:50,560 --> 00:01:53,040
Speaker 1: the only thing we can do to to help make

35
00:01:53,080 --> 00:01:55,880
Speaker 1: printing more environmentally friendly. In fact, there are a lot

36
00:01:55,880 --> 00:01:59,880
Speaker 1: of manufacturers that are looking into various solutions to make

37
00:02:00,320 --> 00:02:04,440
Speaker 1: printing have less of an impact on the environment, that's true.

38
00:02:04,600 --> 00:02:08,920
Speaker 1: One of the leading UH manufacturers who are who are

39
00:02:08,960 --> 00:02:12,160
Speaker 1: doing that at this point is Xerox. They actually have

40
00:02:12,280 --> 00:02:15,560
Speaker 1: a number of different initiatives, not picking on on just

41
00:02:15,680 --> 00:02:18,600
Speaker 1: Xerox or others, but um, it was just earlier this

42
00:02:18,680 --> 00:02:22,880
Speaker 1: year that Cina did an article on something that Xerox

43
00:02:23,120 --> 00:02:27,600
Speaker 1: is doing some researchers in the Palo Alto Research Center. Um,

44
00:02:27,639 --> 00:02:29,080
Speaker 1: you may or may not have heard of it, but

45
00:02:29,120 --> 00:02:31,799
Speaker 1: they've done all kinds of amazing computing things over the

46
00:02:31,840 --> 00:02:34,799
Speaker 1: past few decades. And uh one of the things they've

47
00:02:34,840 --> 00:02:39,400
Speaker 1: come up with is reusable paper. Yeah, it's a really cool.

48
00:02:39,480 --> 00:02:45,280
Speaker 1: This paper is coated with a photo sensitive chemical and um,

49
00:02:45,360 --> 00:02:50,000
Speaker 1: what happens is the chemical turns dark when when it's

50
00:02:50,040 --> 00:02:53,360
Speaker 1: hit with UV light, um so ultra violet light. Uh.

51
00:02:53,560 --> 00:02:55,519
Speaker 1: You see what essentially what we're talking about here is

52
00:02:55,560 --> 00:03:00,120
Speaker 1: a printer that prints disappearing inc uh the right out.

53
00:03:00,120 --> 00:03:03,000
Speaker 1: They're talking about between sixteen and twenty four hours. The

54
00:03:03,000 --> 00:03:05,880
Speaker 1: ink would fade away, and you would come back to

55
00:03:06,080 --> 00:03:07,919
Speaker 1: a sheet of paper that looks just like it did

56
00:03:07,919 --> 00:03:10,640
Speaker 1: when you first put it into the printer. And you

57
00:03:10,680 --> 00:03:12,840
Speaker 1: may say, well, what's what good is that? You know,

58
00:03:12,840 --> 00:03:14,720
Speaker 1: if you print something and it just goes away. Well,

59
00:03:14,720 --> 00:03:16,079
Speaker 1: there are a lot of uses actually, I mean you

60
00:03:16,080 --> 00:03:18,760
Speaker 1: wouldn't want to use it for legal documents. That would

61
00:03:18,760 --> 00:03:21,440
Speaker 1: be a bad use, But a good use would be

62
00:03:21,440 --> 00:03:24,079
Speaker 1: for let's say you have a restaurant and your restaurant

63
00:03:24,160 --> 00:03:28,200
Speaker 1: does daily specials. Well, instead of wasting paper every day,

64
00:03:28,240 --> 00:03:30,400
Speaker 1: printing out these daily specials. You could use the same

65
00:03:30,480 --> 00:03:33,280
Speaker 1: paper to print out your daily special and then the

66
00:03:33,280 --> 00:03:35,800
Speaker 1: next day be ready to go and print again. And

67
00:03:35,880 --> 00:03:41,160
Speaker 1: in fact, Xerox has a printer that, by design, uh

68
00:03:41,280 --> 00:03:45,200
Speaker 1: will wipe a page clean of of its print and

69
00:03:45,240 --> 00:03:48,520
Speaker 1: then print a new page directly on there. So you

70
00:03:48,520 --> 00:03:50,120
Speaker 1: need the same piece of paper. You just run it

71
00:03:50,120 --> 00:03:52,600
Speaker 1: through even if the ink has not faded yet. It

72
00:03:52,880 --> 00:03:56,400
Speaker 1: baths the paper in ultra violet light at such an

73
00:03:56,400 --> 00:03:59,440
Speaker 1: intensity that immediately wipes the page clean and then prints

74
00:03:59,480 --> 00:04:02,160
Speaker 1: it anew so you you can keep using the same

75
00:04:02,200 --> 00:04:05,280
Speaker 1: paper until essentially the paper wears out and it won't

76
00:04:05,360 --> 00:04:08,760
Speaker 1: feed through the printer anymore. So that's it's basically racing

77
00:04:08,760 --> 00:04:12,120
Speaker 1: the paper, right, you know, like you would a magnetic

78
00:04:12,120 --> 00:04:14,960
Speaker 1: storage device or something like exactly, Yeah, you can, uh,

79
00:04:15,160 --> 00:04:18,800
Speaker 1: And it's making paper more like a more like an

80
00:04:18,880 --> 00:04:21,599
Speaker 1: electronic document in a way, because you can just run

81
00:04:21,600 --> 00:04:24,160
Speaker 1: it through a little machine and it clears it and

82
00:04:24,320 --> 00:04:27,239
Speaker 1: gets it ready for the next pass, you know. I UH.

83
00:04:27,480 --> 00:04:30,120
Speaker 1: When we were doing research on this podcast, I found

84
00:04:30,120 --> 00:04:33,120
Speaker 1: an article from the New York Times from November two

85
00:04:33,200 --> 00:04:37,320
Speaker 1: thousand and six something obviously that that park has been

86
00:04:37,360 --> 00:04:40,440
Speaker 1: working on for some time. UM and an anthropologist working

87
00:04:40,480 --> 00:04:43,800
Speaker 1: for Park named Brenda del All said that people are

88
00:04:43,839 --> 00:04:48,880
Speaker 1: generally using paper in offices for display. What that means

89
00:04:49,000 --> 00:04:52,080
Speaker 1: is what what that means is that essentially, rather than

90
00:04:52,200 --> 00:04:54,640
Speaker 1: printing stuff off so that you can save a copy

91
00:04:54,680 --> 00:04:56,480
Speaker 1: of that, you know, put it in your archives, put

92
00:04:56,520 --> 00:04:58,880
Speaker 1: it in your files, and keep it, what people are

93
00:04:58,960 --> 00:05:02,400
Speaker 1: using it for is for meeting. They're printing out presentations

94
00:05:02,400 --> 00:05:06,279
Speaker 1: and other things that you would distribute it at meetings,

95
00:05:06,320 --> 00:05:10,400
Speaker 1: and once they're done, they are discarding them. And I

96
00:05:10,400 --> 00:05:11,880
Speaker 1: think that's one of the things that one of the

97
00:05:11,920 --> 00:05:14,960
Speaker 1: reasons that Park is working on something like this, because

98
00:05:15,240 --> 00:05:19,400
Speaker 1: you could print print these things out on this reusable paper,

99
00:05:19,640 --> 00:05:21,440
Speaker 1: distribute them for the meeting, and then when the meeting

100
00:05:21,520 --> 00:05:23,880
Speaker 1: is over, instead of throwing in the recycle band and

101
00:05:24,000 --> 00:05:25,800
Speaker 1: using the paper and the towner and the energy to

102
00:05:25,920 --> 00:05:29,560
Speaker 1: print that UM, you can just turn back in to

103
00:05:29,839 --> 00:05:32,440
Speaker 1: turn the sheets back in and have them reused later,

104
00:05:32,560 --> 00:05:35,960
Speaker 1: which is very very cool. Yeah, it's it's pretty and

105
00:05:35,960 --> 00:05:38,760
Speaker 1: and like you mentioned, there are other companies that are

106
00:05:38,800 --> 00:05:40,839
Speaker 1: looking into this kind of thing too. A few years ago,

107
00:05:41,400 --> 00:05:45,320
Speaker 1: Toshiba came out with a device that UM and a

108
00:05:45,360 --> 00:05:48,520
Speaker 1: printing method that uses a special kind of ink. It's

109
00:05:48,520 --> 00:05:50,640
Speaker 1: actually got three components and that two of them give

110
00:05:50,640 --> 00:05:52,719
Speaker 1: it a color and the third one removes the color

111
00:05:52,760 --> 00:05:55,200
Speaker 1: when heat is applied. So the idea is that you

112
00:05:55,240 --> 00:05:57,760
Speaker 1: would run this paper through the printer, you print out,

113
00:05:57,800 --> 00:06:01,000
Speaker 1: your documents comes out and kind of a bluish uh tent,

114
00:06:01,120 --> 00:06:04,040
Speaker 1: which is that they actually called the ink e blue,

115
00:06:04,839 --> 00:06:07,520
Speaker 1: and you can hand out the documents and everyone reads them.

116
00:06:07,600 --> 00:06:09,320
Speaker 1: When they're done, they can hand them back to you,

117
00:06:09,400 --> 00:06:11,760
Speaker 1: and then you would run them through a machine that's

118
00:06:11,839 --> 00:06:15,080
Speaker 1: essentially a heater. You'd run it through and it would

119
00:06:15,080 --> 00:06:17,680
Speaker 1: erase the ink from those pages, so you could use

120
00:06:17,680 --> 00:06:20,919
Speaker 1: the paper again. Same sort of concept with zerox, except

121
00:06:20,960 --> 00:06:23,960
Speaker 1: instead of using ultraviolet light, you're using infrared radiation or

122
00:06:23,960 --> 00:06:28,200
Speaker 1: otherwise known as heat um. But it's the same sort

123
00:06:28,200 --> 00:06:31,080
Speaker 1: of idea, recycling paper so that you know you're not

124
00:06:31,160 --> 00:06:33,320
Speaker 1: taking as big a toll on the environment, because that's

125
00:06:33,360 --> 00:06:36,120
Speaker 1: that's one thing, you know, that's something that separates printers

126
00:06:36,160 --> 00:06:39,840
Speaker 1: from other electronic devices like computers and and things like that.

127
00:06:40,320 --> 00:06:44,720
Speaker 1: You have the the energy requirement of the device itself

128
00:06:45,560 --> 00:06:48,960
Speaker 1: that plays a factor, and how environmentally friendly or unfriendly

129
00:06:48,960 --> 00:06:52,000
Speaker 1: it is if it's energy start enabled for example, or

130
00:06:52,120 --> 00:06:55,599
Speaker 1: versus not enabled. But then you have the hardware version

131
00:06:55,600 --> 00:06:58,080
Speaker 1: of it, you have the the toner you have, or

132
00:06:58,120 --> 00:07:01,680
Speaker 1: ink you have the pay for, so you have things

133
00:07:01,720 --> 00:07:04,919
Speaker 1: that make an environmental impact beyond just the energy needed

134
00:07:04,920 --> 00:07:08,479
Speaker 1: to run the device. That's true. UM. Other things that

135
00:07:08,560 --> 00:07:11,360
Speaker 1: you may not be thinking about when you consider your

136
00:07:11,400 --> 00:07:16,120
Speaker 1: printer are the amount of low level ozone that's pumped out.

137
00:07:16,120 --> 00:07:21,520
Speaker 1: If you walk by the exhaust port on your UM printer, UM,

138
00:07:21,560 --> 00:07:23,960
Speaker 1: and you don't drop a couple of proton torpedoes in

139
00:07:23,960 --> 00:07:26,640
Speaker 1: it to blow it up, UM, you'll notice that there's

140
00:07:26,800 --> 00:07:30,400
Speaker 1: it's what seems like hot air. Well, that's actually ozone UM.

141
00:07:30,520 --> 00:07:34,880
Speaker 1: And you know it can actually be a pollutant at

142
00:07:34,920 --> 00:07:37,720
Speaker 1: low levels, you know. And you might say, well, hey,

143
00:07:37,840 --> 00:07:40,600
Speaker 1: maybe my printer is helping fill that hole the ozone there, Well,

144
00:07:40,640 --> 00:07:43,280
Speaker 1: it's not. It stays down here, you know where we are,

145
00:07:43,320 --> 00:07:45,960
Speaker 1: and it's actually a low level pollutant. It's not good

146
00:07:45,960 --> 00:07:48,680
Speaker 1: down here. It's good up there, but not down here. Right.

147
00:07:49,280 --> 00:07:51,920
Speaker 1: And then you have the print cartridges if you have

148
00:07:51,960 --> 00:07:55,560
Speaker 1: an ink jet printer there, they're plastic and they can

149
00:07:55,600 --> 00:07:59,520
Speaker 1: be recycled. Actually, uh, tree Hugger, which is sort of

150
00:07:59,560 --> 00:08:03,200
Speaker 1: a and and strange way a sister site to how

151
00:08:03,240 --> 00:08:06,200
Speaker 1: stuff works dot com. Tree Hugger had an article about

152
00:08:06,280 --> 00:08:10,800
Speaker 1: toner cartridges being recycled into lumber or down cycling where

153
00:08:10,840 --> 00:08:14,840
Speaker 1: you can actually press it into plastic furniture. Um, so

154
00:08:14,920 --> 00:08:16,680
Speaker 1: at least you can do something with those. But there

155
00:08:16,680 --> 00:08:19,080
Speaker 1: are other things to the ink and those, and the

156
00:08:19,160 --> 00:08:23,120
Speaker 1: toner and laser printers is toxic. That stuff is actually dangerous.

157
00:08:23,160 --> 00:08:25,680
Speaker 1: So when you change the toner cartridge general laser printer,

158
00:08:25,880 --> 00:08:29,080
Speaker 1: make sure you wash your hands afterwards, because that's actually dangerous,

159
00:08:29,760 --> 00:08:31,840
Speaker 1: uh stuff, you don't want it to be exposed to

160
00:08:31,880 --> 00:08:34,120
Speaker 1: it for a long time. And and the recycling goes

161
00:08:34,160 --> 00:08:38,400
Speaker 1: the other way to HP printers are using inject cartridges

162
00:08:38,440 --> 00:08:42,920
Speaker 1: that are made from recycled plastic bottles. So yeah, so

163
00:08:43,080 --> 00:08:45,920
Speaker 1: you've got you've got it coming in going in that case. Um,

164
00:08:46,000 --> 00:08:47,920
Speaker 1: so yeah, there there are a lot of companies. You know,

165
00:08:48,040 --> 00:08:51,800
Speaker 1: HP is actually leading in several areas as far as

166
00:08:51,920 --> 00:08:57,000
Speaker 1: uh uh, the the environmentally friendly printing initiatives go. Um,

167
00:08:57,040 --> 00:09:01,040
Speaker 1: they're also looking at discontinuing using and full chemicals when

168
00:09:01,040 --> 00:09:06,000
Speaker 1: they're producing their printers, so uh, things like uh, PPC

169
00:09:06,160 --> 00:09:08,840
Speaker 1: and everything that anything that could possibly have toxins in it.

170
00:09:08,880 --> 00:09:11,680
Speaker 1: Because e waste is becoming a bigger problem too. What

171
00:09:11,679 --> 00:09:14,240
Speaker 1: do you do with your electronics when they've lived out

172
00:09:14,240 --> 00:09:16,800
Speaker 1: their useful life and you've upgraded. You know, if you

173
00:09:16,840 --> 00:09:21,319
Speaker 1: just dump it into the dump, there could be toxic

174
00:09:21,400 --> 00:09:26,000
Speaker 1: chemicals that leach out, and and that's a whole new problem.

175
00:09:26,080 --> 00:09:29,400
Speaker 1: So a lot of companies are looking into alternative ways

176
00:09:29,440 --> 00:09:31,960
Speaker 1: of building their devices so that they don't have these

177
00:09:31,960 --> 00:09:36,520
Speaker 1: harmful chemicals and metals to begin with, which is a

178
00:09:36,679 --> 00:09:38,360
Speaker 1: you know, that's that's a good step in the right

179
00:09:38,400 --> 00:09:43,160
Speaker 1: direction too. And another thing that I discovered was this

180
00:09:43,520 --> 00:09:47,400
Speaker 1: free software from green Print which highlights and removes blank

181
00:09:47,440 --> 00:09:51,720
Speaker 1: pages from your documents. That's I wanted. I'm gonna have

182
00:09:51,760 --> 00:09:54,800
Speaker 1: to sign up for the free the free trial immediately

183
00:09:54,880 --> 00:09:58,079
Speaker 1: because I read about this. Not only does it not

184
00:09:58,200 --> 00:10:00,920
Speaker 1: print blank pages, but it can hecked when you have

185
00:10:01,000 --> 00:10:03,840
Speaker 1: a page that's just say, a header and a footer

186
00:10:03,920 --> 00:10:06,480
Speaker 1: and there's nothing else there, so it's not totally blank,

187
00:10:06,920 --> 00:10:09,760
Speaker 1: but it can detect that and not print that page

188
00:10:09,800 --> 00:10:11,480
Speaker 1: as well. And if any of you have ever printed

189
00:10:11,480 --> 00:10:14,120
Speaker 1: a web page, like send a web page straight to print,

190
00:10:14,200 --> 00:10:16,199
Speaker 1: you probably ended up with that final piece of paper

191
00:10:16,240 --> 00:10:19,760
Speaker 1: that has nothing useful on it whatsoever. Green Print theoretically

192
00:10:20,120 --> 00:10:24,000
Speaker 1: eliminates that, right that that's true. I have no idea

193
00:10:24,080 --> 00:10:26,440
Speaker 1: what it would do for those manuals that have this

194
00:10:26,480 --> 00:10:30,400
Speaker 1: page intentionally left blank on it, however, Right, Well, that's

195
00:10:30,440 --> 00:10:33,320
Speaker 1: that's really for duplex printing anyway. So we're talking about

196
00:10:33,320 --> 00:10:35,560
Speaker 1: single side printing here, and that's true. If your printer

197
00:10:35,920 --> 00:10:39,040
Speaker 1: supports duplex printing, which is printing on both sides, you're

198
00:10:39,120 --> 00:10:42,360
Speaker 1: using one last piece of paper. Um. I we have

199
00:10:42,400 --> 00:10:44,040
Speaker 1: a printer here in the office that I prefer to

200
00:10:44,120 --> 00:10:46,160
Speaker 1: use because it prints on both sides of the paper.

201
00:10:46,280 --> 00:10:51,600
Speaker 1: They're also other initiatives. Rico, another printer manufacturer from Japan,

202
00:10:51,679 --> 00:10:54,240
Speaker 1: for a while in the was working on a system

203
00:10:54,280 --> 00:10:56,120
Speaker 1: that would remove the towner from the paper and it

204
00:10:56,160 --> 00:10:59,240
Speaker 1: would work up to ten times. But apparently the company

205
00:10:59,320 --> 00:11:02,160
Speaker 1: is no longer offering this, according to the article in

206
00:11:02,200 --> 00:11:04,760
Speaker 1: the New York Times that I read, So I'm guessing

207
00:11:04,760 --> 00:11:07,520
Speaker 1: that it didn't take off. Maybe it was ahead of

208
00:11:07,520 --> 00:11:10,760
Speaker 1: its time. If it was in the people weren't as

209
00:11:10,800 --> 00:11:15,240
Speaker 1: interested in conserving before the costs of energy were increasing. Um.

210
00:11:15,280 --> 00:11:18,200
Speaker 1: But another thing that would would actually use its own

211
00:11:18,200 --> 00:11:22,319
Speaker 1: electricity to power it. Um in November for the anniversary

212
00:11:22,360 --> 00:11:25,840
Speaker 1: cover of Esquire magazine, it's going to use e ink

213
00:11:26,240 --> 00:11:31,200
Speaker 1: Electronic inc Um, which is essentially a series of plastic

214
00:11:31,240 --> 00:11:34,400
Speaker 1: capsules that have die in them, and when a charge

215
00:11:34,440 --> 00:11:37,520
Speaker 1: is applied to one side, it pulls the die to

216
00:11:37,679 --> 00:11:39,680
Speaker 1: that side, and when it is pulled to the other

217
00:11:39,840 --> 00:11:43,360
Speaker 1: the charges applied to the other side of the electronic paper, UH,

218
00:11:43,400 --> 00:11:46,000
Speaker 1: the die has pulled to that side. So in effect,

219
00:11:46,000 --> 00:11:48,160
Speaker 1: what it does is it can you can actually change

220
00:11:48,160 --> 00:11:50,040
Speaker 1: what it says in the paper depending on where the

221
00:11:50,080 --> 00:11:53,319
Speaker 1: electric charge is applied. It's sort of like uh an

222
00:11:53,320 --> 00:11:57,320
Speaker 1: electric TV one of the like an LCD screen where

223
00:11:57,320 --> 00:11:59,720
Speaker 1: it has the different pixels and everything is you know,

224
00:11:59,760 --> 00:12:02,440
Speaker 1: it's charge is applied for to a certain point on

225
00:12:02,440 --> 00:12:06,440
Speaker 1: that screen for a certain uh to receive a certain color. Well,

226
00:12:06,440 --> 00:12:09,320
Speaker 1: in this case, it's basically black or white or you know,

227
00:12:09,400 --> 00:12:13,760
Speaker 1: a color and white. UM. But it's going to allow

228
00:12:13,880 --> 00:12:17,160
Speaker 1: Esquire to have words that scroll across the front of

229
00:12:17,200 --> 00:12:19,559
Speaker 1: the magazine. The thing is, it's only going to work

230
00:12:19,559 --> 00:12:21,200
Speaker 1: for a certain amount of time because in order to

231
00:12:21,240 --> 00:12:23,840
Speaker 1: do that, it's got to keep a charge running to

232
00:12:23,960 --> 00:12:27,800
Speaker 1: do that. Xerox has a printer that will print pages

233
00:12:27,920 --> 00:12:32,360
Speaker 1: of This is called guricon or gyraicon um and it's

234
00:12:32,400 --> 00:12:36,680
Speaker 1: reusable paper. It works similarly basically the instead of having

235
00:12:37,440 --> 00:12:39,480
Speaker 1: a ball where the ink moves from one side to

236
00:12:39,520 --> 00:12:43,080
Speaker 1: the other, the balls are basically black and white, um,

237
00:12:43,120 --> 00:12:45,240
Speaker 1: you know, on one side or the other, and they

238
00:12:45,240 --> 00:12:48,160
Speaker 1: flip over depending on where the charge is applied. But

239
00:12:48,240 --> 00:12:51,400
Speaker 1: basically in that situation, uh, you print it one time

240
00:12:51,440 --> 00:12:54,520
Speaker 1: and it keeps that there doesn't have to continually have

241
00:12:54,600 --> 00:12:58,120
Speaker 1: a charge because it's the image is not changing. Um.

242
00:12:58,120 --> 00:13:00,800
Speaker 1: But you could use the reusable pay prot do that too,

243
00:13:00,800 --> 00:13:03,480
Speaker 1: and the electronic ink would give you the opportunity to

244
00:13:04,160 --> 00:13:08,200
Speaker 1: have the same page and only use one page and

245
00:13:08,240 --> 00:13:10,240
Speaker 1: have it change depending on what it is that you

246
00:13:10,280 --> 00:13:14,040
Speaker 1: need to display. Wow, that's pretty cool. And for you

247
00:13:14,200 --> 00:13:16,520
Speaker 1: office managers out there who are kind of curious as

248
00:13:16,520 --> 00:13:20,679
Speaker 1: to how much how much waste both environmental and just

249
00:13:21,240 --> 00:13:24,720
Speaker 1: solid waste your printers are generating, Xerox has come up

250
00:13:24,760 --> 00:13:28,199
Speaker 1: with a neat little tool for you called a sustainability calculator,

251
00:13:28,800 --> 00:13:31,240
Speaker 1: And you just go to the to xerox is page

252
00:13:31,240 --> 00:13:34,240
Speaker 1: and look for the sustainability calculator. What it does, is it?

253
00:13:34,240 --> 00:13:37,079
Speaker 1: It lets you put in a couple of points of input,

254
00:13:37,760 --> 00:13:41,880
Speaker 1: mainly how fast your printers work, how many you have, um,

255
00:13:42,000 --> 00:13:45,280
Speaker 1: how many images you print on average in a in

256
00:13:45,320 --> 00:13:48,160
Speaker 1: a certain period of time, and then it calculates how

257
00:13:48,240 --> 00:13:51,280
Speaker 1: much how much solid waste it produces, how many how

258
00:13:51,280 --> 00:13:55,200
Speaker 1: many greenhouse gases it might produce, um, how much energy

259
00:13:55,240 --> 00:13:59,160
Speaker 1: it consumes. It can really help you see what your

260
00:13:59,320 --> 00:14:02,319
Speaker 1: carbon foot print is as far as your printing side

261
00:14:02,320 --> 00:14:05,880
Speaker 1: of operations go, and maybe make some changes if you

262
00:14:06,040 --> 00:14:09,920
Speaker 1: if if things are looking kind of grim, you can

263
00:14:10,000 --> 00:14:12,840
Speaker 1: maybe downsize the printers and make more have more of

264
00:14:12,840 --> 00:14:16,120
Speaker 1: a centralized printing location, and that can help out a lot.

265
00:14:17,120 --> 00:14:19,760
Speaker 1: Of course, the easiest way to uh, to minimize this

266
00:14:20,520 --> 00:14:24,280
Speaker 1: waste and electronic or impact of electronic devices is to

267
00:14:24,640 --> 00:14:26,880
Speaker 1: use them as minimally as possible. Don't print more than

268
00:14:26,920 --> 00:14:29,320
Speaker 1: you need to. And that's that basically comes down to

269
00:14:29,680 --> 00:14:32,520
Speaker 1: you and me, right Yeah, like I said, putting the

270
00:14:32,600 --> 00:14:36,240
Speaker 1: human element right back in there. Um. Yeah, the the

271
00:14:36,240 --> 00:14:38,760
Speaker 1: these manufacturers are working really hard to make things as

272
00:14:38,800 --> 00:14:40,880
Speaker 1: easy as possible for it to be green. Now it's

273
00:14:40,960 --> 00:14:43,000
Speaker 1: up for us to carry it the rest of the way.

274
00:14:43,400 --> 00:14:46,080
Speaker 1: I guess we should probably wrap this up. We've talked

275
00:14:46,080 --> 00:14:47,960
Speaker 1: about a lot of different subjects here, but if you

276
00:14:48,000 --> 00:14:50,200
Speaker 1: want to learn more about just one in particular, I

277
00:14:50,280 --> 00:14:54,040
Speaker 1: suggest reading how electronic ink works at how stuff works

278
00:14:54,080 --> 00:14:56,440
Speaker 1: dot com. And we'll talk to you again really soon.

279
00:14:58,880 --> 00:15:01,000
Speaker 1: Let us know what you think, send an email to

280
00:15:01,080 --> 00:15:07,640
Speaker 1: podcast and how stuff works dot come. Brought to you

281
00:15:07,680 --> 00:15:11,040

282
00:15:11,080 --> 00:15:11,200
Speaker 1: you
