Latest / Stuff You Should Know / How Reverse Osmosis Will Save the World
Transcript
- 0:01Speaker 1: Welcome to Stuff You Should Know, a production of I
- 0:04Speaker 1: Heart Radio. Hey, and welcome to the podcast. I'm Josh,
- 0:13Speaker 1: and there's Chuck and Jerry's over there somewhere on the
- 0:16Speaker 1: other side of the membrane because she's insane in the membrane,
- 0:22Speaker 1: and this is stuff you should know. I think it's
- 0:28Speaker 1: pretty funny that I used to love Cyper Hill. Oh.
- 0:32Speaker 1: I downloaded their album again, like the other day. Yeah,
- 0:35Speaker 1: and it's it still holds up, insane, got no brain.
- 0:40Speaker 1: I love that guy. I don't remember his name actually,
- 0:43Speaker 1: now I think about I don't remember the other dude's
- 0:45Speaker 1: name either. I just remember their DJ was DJ Muggs, right.
- 0:48Speaker 1: That sounds about right. Yeah, I remember his name. I
- 0:51Speaker 1: don't remember the other like the two ms I don't remember.
- 0:53Speaker 1: I think they liked marijuana smoke if I remember here
- 0:56Speaker 1: there Yeah, yeah, yeah. They had a song about a bomb,
- 1:01Speaker 1: I believe. Yeah, it's from that's right. I'm gonna go
- 1:05Speaker 1: listen to that now. You should listen to the album again.
- 1:08Speaker 1: It's still pretty good. They I mean they're talking about
- 1:10Speaker 1: like shooting people and everything, just like come on, no,
- 1:13Speaker 1: you don't do anything like that. But um, you know
- 1:18Speaker 1: there are other stuff. The other stuff they talked about.
- 1:20Speaker 1: It's pretty good. Yeah, So I am literally going to
- 1:22Speaker 1: go listen to that now and you can talk about
- 1:24Speaker 1: reverse Osmosis. Alright. So, Chuck, you made a reference before
- 1:28Speaker 1: we started um recording that sounded really familiar to me,
- 1:32Speaker 1: but it's probably only going to sound familiar to like
- 1:34Speaker 1: eight other people. You referenced Osmosis Jones, right, and I
- 1:39Speaker 1: was like, who is that? That sounds really familiar and
- 1:42Speaker 1: I cannot, for the life of me place it, and
- 1:44Speaker 1: then you said it's from our TV show. Still can't
- 1:47Speaker 1: really place it, but now I kind of know what
- 1:49Speaker 1: you're talking about. Actually, and now I'm doubting myself. Okay,
- 1:53Speaker 1: I think Osmosis Jones is uh is a movie? Okay, yeah,
- 2:01Speaker 1: I think you're thinking of Nash Pluto. No no, no,
- 2:04Speaker 1: Osmosis Jones is Chris Chris Rock animated movie. Okay, I
- 2:08Speaker 1: got it mixed up with something. Are are? One of
- 2:11Speaker 1: our co star actors used to say a lot, which
- 2:14Speaker 1: was to say Jones on the end of anything That's right,
- 2:18Speaker 1: And I think it reminded me of Osmosis Jones. But
- 2:21Speaker 1: I have COVID, so I'm all over the place. You
- 2:24Speaker 1: are all over the place. But one thing where you
- 2:26Speaker 1: really nailed at, Chuck, and I'm really appreciative that you
- 2:28Speaker 1: brought up osmosis, Jones, is because we're talking about osmosis today,
- 2:32Speaker 1: and in particular, we're gonna focus mostly on reverse osmosis,
- 2:36Speaker 1: although we'll have to talk about regular osmosis as well.
- 2:39Speaker 1: How does that sound? Yeah? I mean, can I go
- 2:42Speaker 1: ahead and talk about regular osmosis? I mean, is there
- 2:48Speaker 1: any better time? I can't think of a better time,
- 2:51Speaker 1: certainly not in our Radium Girls episode. Yeah. I mean
- 2:55Speaker 1: this is basically like if you took chemistry in high
- 2:58Speaker 1: school and you have forgot everything about it since then,
- 3:03Speaker 1: you might hear the words ostomosis and reverse osmosis and
- 3:05Speaker 1: be like, wait a minute, that's that's tickling my brain
- 3:08Speaker 1: a little bit. I know I knew that at one point.
- 3:11Speaker 1: So just a little basic chemistry. One oh one is
- 3:15Speaker 1: let's just talk about saltwater. Lay it on, um. Saltwater
- 3:19Speaker 1: is going to figure in. Have almost said heavenly heavily here,
- 3:24Speaker 1: because as you'll see, reverse osmosis is a great kind
- 3:28Speaker 1: of modern way too, sort of the hip new way
- 3:31Speaker 1: to take salt from water so we can drink it
- 3:34Speaker 1: like you're talking of. If you make a cup of
- 3:36Speaker 1: salt water and you gargle it, you know for your throat,
- 3:40Speaker 1: you have some left over, you could use reverse osmosis
- 3:43Speaker 1: to convert it back into regular water. That's real. Don't
- 3:46Speaker 1: waste it. And we we talked about I know, we've
- 3:48Speaker 1: done stuff on desalination. We did. We did an episode
- 3:54Speaker 1: way back in the day hauled um, is it possible
- 3:58Speaker 1: to drink the ocean or something like that. Uh, what
- 4:02Speaker 1: exactly what happens when we run out of water? I
- 4:04Speaker 1: think is what it was. That was way off And
- 4:08Speaker 1: then I'm pretty sure we talked about drinking the ocean.
- 4:10Speaker 1: We also did one on manufacturing water too, but yeah, yeah, yeah,
- 4:13Speaker 1: we talked about this desalinating before. That's right. So back
- 4:17Speaker 1: to chemistry one on one. It's very simple. I don't
- 4:21Speaker 1: know if you folks remember what a solution is, but
- 4:23Speaker 1: a solution is when, in this case it's with salt water,
- 4:28Speaker 1: you have a solvent, which is the water, and then
- 4:31Speaker 1: you have the salute, which is the salt or dissolve
- 4:36Speaker 1: in the water or whatever else you want to to
- 4:40Speaker 1: have in there. And this whole thing together is called
- 4:43Speaker 1: a solution and if you put this solution in a YouTube,
- 4:47Speaker 1: not y o u t ub dot com, but a
- 4:51Speaker 1: literal beaker shaped like a tube, and you had a
- 4:54Speaker 1: semi permeable membrane in the middle. Let's just go ahead
- 4:57Speaker 1: and say gortex in this case, because that's what that is.
- 5:00Speaker 1: Shout out cortex. And you poured this stuff in there
- 5:04Speaker 1: on one side, and then you poured regular water on
- 5:07Speaker 1: the other side. That water on the other side is
- 5:10Speaker 1: gonna want to just balance out. It's gonna want to
- 5:12Speaker 1: seek thermodynamic equilibrium, and it's gonna fight its way through there,
- 5:17Speaker 1: through that membrane until everything is nice and level. It's
- 5:22Speaker 1: got this osmotic pressure and it's gonna push through there
- 5:25Speaker 1: until it reaches that equilibrium because that's where it wants
- 5:28Speaker 1: to be. And that's yeah, because nature is seeking equilibrium.
- 5:33Speaker 1: And because the the higher concentrated side is separated by
- 5:39Speaker 1: a membrane from the lower concentrated side, it's got to
- 5:42Speaker 1: make it through that membrane to even things out, and
- 5:44Speaker 1: as it does, it's actually gonna push the concentrated side
- 5:48Speaker 1: up the beaker because it's moving into that side through
- 5:51Speaker 1: the membrane. It's pretty amazing stuff, but yeah, that's I mean,
- 5:55Speaker 1: that's osmosis, Chuck, nicely done. Why don't you tackle reverse
- 5:59Speaker 1: osmosis m so reverse osmosis so osmosis what you just
- 6:04Speaker 1: described as a passive process that happens because the atmosphere
- 6:09Speaker 1: above us has weight like air has weight. And in fact,
- 6:13Speaker 1: if you took one square inch of a column of
- 6:17Speaker 1: atmosphere of air from the surface of the Earth all
- 6:20Speaker 1: the way up to the exosphere, the tippy top of
- 6:22Speaker 1: the atmosphere, that one square inch column with way about
- 6:26Speaker 1: fourteen and three quarter pounds. So another way to put
- 6:29Speaker 1: it is, there's fourteen point seven five pounds per square
- 6:32Speaker 1: ince of pressure at surface level on Earth. Because of
- 6:36Speaker 1: that pressure, we have that osmotic pressure, and so the
- 6:40Speaker 1: stuff can kind of move from one side to the other,
- 6:42Speaker 1: from lower concentration to higher concentration to balance things out.
- 6:46Speaker 1: And it's all because of that. But the whole thing
- 6:48Speaker 1: is a passive process. There's nothing moving. This is not
- 6:51Speaker 1: it's not requiring energy to take place. Okay, with reverse osmosis,
- 6:58Speaker 1: you're doing the opposite of what you just described, and
- 7:00Speaker 1: it actually does take energy. You have to create more
- 7:03Speaker 1: pressure that will overcome the the natural osmotic pressure. And
- 7:07Speaker 1: what you're doing in that case is actually taking the
- 7:10Speaker 1: solvent in this case water and moving it out against
- 7:15Speaker 1: its natural will, against every fiber of its being screaming
- 7:20Speaker 1: at you that no, this is wrong, this is an
- 7:22Speaker 1: importance against nature. UM. It's moving it through that membrane
- 7:27Speaker 1: to the other side, to the lower concentration. So what
- 7:30Speaker 1: you're doing is taking a concentrated solution and making it
- 7:33Speaker 1: even more concentrated by taking out the the in this
- 7:37Speaker 1: case the water. So what you have on one side
- 7:40Speaker 1: is saltwater and then saltwater concentrate, and what you have
- 7:43Speaker 1: on the other side is just pure water what they
- 7:45Speaker 1: call ultra pure water UM, and that's basically reverse osmosis. Yeah.
- 7:51Speaker 1: So if you look into UH to make saltwater not saltwater,
- 7:56Speaker 1: and you had a couple of tanks and on one
- 7:58Speaker 1: side you had that UM, that solution of salt water
- 8:02Speaker 1: or let's just call it saltwater, and it's under that
- 8:06Speaker 1: you know, regular osmotic pressure that we were talking about.
- 8:10Speaker 1: It's all happy and well. You gotta apply I think
- 8:14Speaker 1: about fifty to sixty bars of pressure and you gotta
- 8:17Speaker 1: push that thing through there, and those salt molecules are
- 8:20Speaker 1: too big to pass through the membrane, and it's it's
- 8:23Speaker 1: really pretty easy. It's not the most I mean, I
- 8:26Speaker 1: can't go out and build one of these, but it's
- 8:28Speaker 1: not the most complicated process. It's really just if you
- 8:32Speaker 1: think about trying to fit something too big through a
- 8:35Speaker 1: small hole, it's not gonna go. Everything else will, so
- 8:38Speaker 1: it's left over is salt or you know, sort of
- 8:41Speaker 1: a briny solution, right, And what you're saying is like
- 8:44Speaker 1: using pressure to push it through, Like that's that basically
- 8:47Speaker 1: makes sense. But but when you're almost you're not using
- 8:51Speaker 1: pressure to to push it. You're just increasing the pressure
- 8:54Speaker 1: in that concentration. And then reverse OUs moostis happens by
- 8:58Speaker 1: magic because you've over come that natural losmotic pressure. And
- 9:02Speaker 1: now you know to the to the solution or the
- 9:04Speaker 1: salt water and the ultrapure water. You know, what's up
- 9:08Speaker 1: is down. Nothing makes sense anymore. All bets are off
- 9:11Speaker 1: because you've overcome that natural losmotic pressure. So it's not
- 9:14Speaker 1: exactly like pushing it through a membrane, which is how
- 9:16Speaker 1: my brain kept going. Um, there's like it's it's a
- 9:20Speaker 1: little more magic than that. But the upshot of it
- 9:23Speaker 1: is that that membrane you're using is so small, the
- 9:26Speaker 1: pores in it are so small that only water can
- 9:29Speaker 1: make it through, and water, it turns out, was really small, Chuck.
- 9:32Speaker 1: You want to know how small water is, well, prepare
- 9:36Speaker 1: for it, because I'm about to lay it on you.
- 9:38Speaker 1: The average, actually it wouldn't be average, would be exactly
- 9:41Speaker 1: the same size. The size of a water molecule is
- 9:44Speaker 1: point to seven nanometers, which is twenty seven hundred thousands
- 9:51Speaker 1: of a micron, and a micron is a millionth of
- 9:55Speaker 1: a meter, So a human hair's diameter is about seventy microns.
- 10:01Speaker 1: A water molecule is hundred thousands of one micron. So
- 10:07Speaker 1: it's really really small, which means that if you can
- 10:10Speaker 1: make a membrane that is small enough, large enough for
- 10:14Speaker 1: water to get through, but not much larger than that,
- 10:17Speaker 1: it's going to keep a lot of other stuff from
- 10:20Speaker 1: passing through that membrane as well. That's right. Uh, maybe
- 10:24Speaker 1: we should take a break and we'll talk a little
- 10:26Speaker 1: bit about what we've been teasing, which is desalination right
- 10:30Speaker 1: after this. All right, so if you want to, I mean,
- 10:57Speaker 1: water is is a commodity. We've been talking about that
- 10:59Speaker 1: a lot on the show for a while and kind
- 11:02Speaker 1: of trying to bang that drum that potable drinking water. Uh,
- 11:07Speaker 1: you know, it could be a crisis in the near
- 11:09Speaker 1: or far future for the world. So there have been
- 11:12Speaker 1: a lot of efforts over the years, uh, kind of
- 11:14Speaker 1: to try and get ahead of this a little bit.
- 11:16Speaker 1: And the ocean is an obvious place to look because
- 11:19Speaker 1: there's a lot of water out there. So the efforts
- 11:22Speaker 1: have been made since I believe about the nineteen fifties
- 11:25Speaker 1: to try and turn that that salt water into something
- 11:28Speaker 1: that people can drink or at least use, you know,
- 11:31Speaker 1: for other purposes. Um, you know, not necessarily like potable water,
- 11:34Speaker 1: but you know, useing in industries and stuff like that. Yeah. Um.
- 11:39Speaker 1: In particular, we've known how to like distill or to
- 11:42Speaker 1: get water from saltwater pure water from saltwater using distillation,
- 11:46Speaker 1: but that uses a lot of energy where you boil
- 11:49Speaker 1: the water. It takes a lot of energy to boil
- 11:50Speaker 1: water and boil the salt out of water. Um. And
- 11:54Speaker 1: that was kind of the first attempt. But I think
- 11:55Speaker 1: in the sixties they started to say, um, maybe we
- 11:59Speaker 1: could take this ousmosis thing that's happening all over the
- 12:02Speaker 1: place and reverse it and and we could use that
- 12:05Speaker 1: to get salt out of water. Yeah, And they figured
- 12:08Speaker 1: out how to do it and it was going pretty well,
- 12:10Speaker 1: but they didn't have a great way to do it
- 12:11Speaker 1: on a large scale that made it kind of financially
- 12:15Speaker 1: practical to do until a couple of engineering grad students
- 12:19Speaker 1: that U c l A. Came along. One was named
- 12:22Speaker 1: Sydney Loebe and the other one's name Strini Bassa surre Rajan. Boy,
- 12:28Speaker 1: you're gonna nail that. Yeah you did? Would you say
- 12:31Speaker 1: it another way or no? No? And I don't have
- 12:35Speaker 1: their names in front of me, but I think that
- 12:37Speaker 1: you it sounded pretty believable, Chuck. You know what I do.
- 12:41Speaker 1: Here's a little trick for you. And of course this
- 12:43Speaker 1: is only works is if you're pronouncing the parts correctly.
- 12:46Speaker 1: But I just like I looked them up on the
- 12:48Speaker 1: internet and call them and ask them how to say
- 12:50Speaker 1: their names. Well, you could sometimes I look on YouTube
- 12:52Speaker 1: see if they're interviewed, but um, I just spell it
- 12:56Speaker 1: out dictionary style, like syllable by syllable with big spaces
- 13:00Speaker 1: in between. Oh yeah, yeah, and then do you make
- 13:02Speaker 1: the one with the emphasis the syllable with emphasis like
- 13:05Speaker 1: in all caps or something like that sometimes, or they'll
- 13:09Speaker 1: scribble underline or you know, none of it's like like
- 13:12Speaker 1: real dictionary style. Uh, yeah, I don't. I don't even
- 13:19Speaker 1: know what swat is. It's the upside down. Oh that's
- 13:23Speaker 1: a schwa. Yes, what's the word we were talking about
- 13:26Speaker 1: the other day that I loved swing? I hate swing?
- 13:32Speaker 1: You hate I think everybody hated schwing for a little while.
- 13:36Speaker 1: They're yeah, not a fan, So all right, So I
- 13:39Speaker 1: nailed those two names. They were grad students at u
- 13:41Speaker 1: C l A. And they were the two gentlemen who
- 13:44Speaker 1: came up with this basically the first practical reverse osmosis
- 13:50Speaker 1: membrane using cellulose acetate. And it was the first time
- 13:54Speaker 1: that they could actually use this on a large scale
- 13:57Speaker 1: and they did so. Uh, this is actually more of
- 13:59Speaker 1: a small scale operation, but the idea was the same
- 14:03Speaker 1: at a place in Coalinga, California, nineteen sixty five that
- 14:07Speaker 1: was online for seven years and worked pretty well from
- 14:11Speaker 1: what I understand. Yeah, and at the very least it
- 14:13Speaker 1: was a very good um proof of concept, I guess,
- 14:16Speaker 1: you know. And it's showed that yeah, with this new
- 14:18Speaker 1: this new ascetate membrane, you know, like you were saying,
- 14:22Speaker 1: you can get a lot more through it at a
- 14:24Speaker 1: much faster pace. Um, and that's kind of what you
- 14:27Speaker 1: need if you're going to ramp this up for industrial
- 14:29Speaker 1: style production. And they definitely did. That was nineteen sixty five,
- 14:33Speaker 1: you said it went on online. As of two thousand nineteen,
- 14:39Speaker 1: there's now a hundred and seventy seven different countries producing
- 14:43Speaker 1: desalinated water using reverse osmosis. And in fact, there's I
- 14:48Speaker 1: think sixteen thousand desalination plants in the world by far,
- 14:52Speaker 1: the most are in Africa and the Middle East, but
- 14:55Speaker 1: there's a total capacity now today, just since nineteen sixty five,
- 14:58Speaker 1: this is developed where hundred million cubic meters of fresh
- 15:02Speaker 1: water can be produced everyday worldwide. That is just not
- 15:08Speaker 1: so from taking seawater and using reverse osmosis to turn
- 15:14Speaker 1: it into pure fresh water. That's right. And uh, those
- 15:18Speaker 1: numbers are growing and they need to, which is which
- 15:20Speaker 1: is a great thing. I love it when we figured
- 15:22Speaker 1: out how to do something and then it's just a
- 15:25Speaker 1: matter of sort of getting more and more of it going. Yeah, yeah,
- 15:30Speaker 1: I mean yeah, And I think from what I understand,
- 15:32Speaker 1: you know, everybody's trying to figure out like UM, you
- 15:35Speaker 1: know how to build on efficiencies or how to continue
- 15:39Speaker 1: to scale up and how to use less energy and
- 15:42Speaker 1: time and all that. But it's it's it seems to
- 15:45Speaker 1: be one of those technologies as roughly the same as
- 15:47Speaker 1: it was when they invented it initially and basically UM
- 15:52Speaker 1: to kind of give just a little bit of detail
- 15:54Speaker 1: on on how it goes, it's it's you you take
- 15:57Speaker 1: in seawater. Most reverse osmosis plant that UM desalinate seawater
- 16:02Speaker 1: built pretty close to the sea. UM because transportation is
- 16:06Speaker 1: is a big cost. So if you can just pipe
- 16:08Speaker 1: it right from the sea into your plant, that saves
- 16:11Speaker 1: on a lot of costs and time and energy. UM.
- 16:13Speaker 1: It's ramped up using pumps and then it's run through
- 16:17Speaker 1: the reverse osmosis filters and under pressure that like you said,
- 16:22Speaker 1: I think sixty bars of pressure, so it's a pressurized
- 16:26Speaker 1: so that it overcomes the natural osmotic pressure. And it
- 16:30Speaker 1: is it goes over, not through like I keep wanting
- 16:34Speaker 1: to think of it going through, like there's a membrane
- 16:36Speaker 1: in the water's way and it has to go through
- 16:39Speaker 1: this membrane. That's not how it goes. It goes through
- 16:41Speaker 1: a tube and in the center of the tube is
- 16:44Speaker 1: another tube um that's wrapped in the membrane and the
- 16:51Speaker 1: concentrate the salt keeps going, but the water that's in
- 16:55Speaker 1: that concentrate, that salt, that solution um goes through the
- 16:59Speaker 1: membrane into that inner tube, and the inner tube pushes
- 17:03Speaker 1: that fresh water, that that reverse osmosis water along um
- 17:09Speaker 1: into what's called the production water stream, and then that
- 17:14Speaker 1: salt water just continues along its way back out to
- 17:17Speaker 1: the ocean under pressure and what's called the reject stream,
- 17:20Speaker 1: which is not nice, but it's you know, an accurate description.
- 17:24Speaker 1: And then that's how like you would desalinate water. It
- 17:29Speaker 1: is reject reject water stream. Sure as the reject stream. Sure, Okay,
- 17:34Speaker 1: there you go. When you have three names, I think
- 17:37Speaker 1: that's more an album title. So maybe just reject stream. Yeah,
- 17:42Speaker 1: I think reject stream is great. And we'll talk about
- 17:45Speaker 1: that more later. Not the band, but are the imaginary
- 17:50Speaker 1: band the album? Yeah? And who's playing what? Uh So,
- 17:56Speaker 1: reverse osmosis is not the kind of thing that you
- 17:59Speaker 1: can just you for salt water. It's a great application,
- 18:02Speaker 1: of course, but it can you know, you're filtering something out,
- 18:05Speaker 1: so you can filter out almost anything. Um, if you
- 18:07Speaker 1: have a local water source that has way too much fluoride,
- 18:10Speaker 1: you can filter out some of that fluoride in a
- 18:12Speaker 1: much more efficient way than you can using charcoal filtrations. Uh.
- 18:17Speaker 1: We did a show on fluoride like a thousand years ago.
- 18:20Speaker 1: I remember that one. Yeah, I think it's a floride
- 18:22Speaker 1: making a stupid that. I feel like that was one
- 18:25Speaker 1: of our like fifteen minute episodes or something. Yeah, easily
- 18:29Speaker 1: at most, I think some kind You talked about the
- 18:32Speaker 1: ultrapure water, which can is the you know, one side
- 18:35Speaker 1: of the result, and some companies need that stuff and
- 18:38Speaker 1: some industries need that stuff. So sometimes you're filtering out
- 18:42Speaker 1: things just to get that ultrapure water to use as
- 18:46Speaker 1: an industry application. I think when you're manufacturing electronics sometimes,
- 18:51Speaker 1: or pharmaceuticals, um, different kind of chemicals, certain medical applications.
- 18:56Speaker 1: We talked about wastewater a lot of the toilet to
- 18:59Speaker 1: tap that's using reverse osmosis. Right on our best episodes,
- 19:05Speaker 1: I think, do you think so wastewater treatment? I mean,
- 19:08Speaker 1: it's hard to say best episode when we've been doing
- 19:11Speaker 1: this for eighty years, but uh, I thought it was
- 19:14Speaker 1: a good one. Yeah, I thought it was good too.
- 19:17Speaker 1: I was just surprised to hear you say that. But
- 19:19Speaker 1: that's yeah, and toilets just happens. It's just gross, but
- 19:22Speaker 1: it's it's sensible for sure. And the point of it
- 19:27Speaker 1: is it's gross entirely in your mind. Like when you
- 19:31Speaker 1: raise that glass of water that used to be waste water,
- 19:35Speaker 1: it's just water after it's undergone reverse osmosis. Like that's it.
- 19:39Speaker 1: There's nothing else in it. There's not even a memory
- 19:41Speaker 1: of that kind of stuff, you know, because despite what
- 19:44Speaker 1: homeopaths say, there's nothing in that water except for the water.
- 19:49Speaker 1: There are some things that make it through UM, what
- 19:52Speaker 1: are called containments of emerging concern UM. Some kinds of
- 19:55Speaker 1: pharmaceuticals can actually make it through. They're small enough that
- 19:58Speaker 1: they make it through with the water molecules. But for
- 20:01Speaker 1: the most part, most everything else is filtered out by
- 20:04Speaker 1: reverse osmosis UM. And one of the reasons that are
- 20:09Speaker 1: One of the other industries that use it chuck is
- 20:11Speaker 1: like the beverage industry, because you can take tap water
- 20:15Speaker 1: from anywhere, run it through reverse osmosis filter and move
- 20:20Speaker 1: even more of it through faster because you're not having
- 20:23Speaker 1: you're not dealing with a briny salt solution. Like this
- 20:26Speaker 1: is just tap water and you're convert you're basically turning
- 20:29Speaker 1: it into a blank slate. So you could make like
- 20:31Speaker 1: a soft drink taste the same anywhere in the world
- 20:35Speaker 1: just by using the local tap water to produce it,
- 20:37Speaker 1: you know, and now you have production facilities all over
- 20:40Speaker 1: the world, so you don't have to transport it because
- 20:43Speaker 1: you're able to start with reverse osmosis water. Oh yeah,
- 20:46Speaker 1: they use it, uh, separating away from milk. They use
- 20:51Speaker 1: it in the wine industry some now they use it
- 20:54Speaker 1: to make maple syrup. They remove that that sugary goodness
- 20:57Speaker 1: from the water and the sap. What else, um, let's see,
- 21:03Speaker 1: they use it for recycling. One of the other this
- 21:06Speaker 1: is a big big deal is we'll see um. When
- 21:10Speaker 1: you when you produce all sorts of stuff um through
- 21:13Speaker 1: industrial processes or if you recycle things, you have to
- 21:17Speaker 1: use all sorts of other chemicals you produce, like sorts
- 21:20Speaker 1: of wastewater is a byproduct, and wastewater is really hard
- 21:23Speaker 1: to get rid of without contaminating other water because it
- 21:26Speaker 1: mixes really well. So one of the good things you
- 21:28Speaker 1: can do is take wastewater, run it through reverse osmosis,
- 21:32Speaker 1: and you're basically catching all of the stuff that was
- 21:36Speaker 1: once mixed in with the water um and making it
- 21:39Speaker 1: into a much more disposable, much closer to solid form,
- 21:43Speaker 1: and then also producing reverse osmosis water that you can
- 21:46Speaker 1: use for all sorts of other applications as well. And
- 21:50Speaker 1: speaking of recycling, a little bit different kind of recycling.
- 21:54Speaker 1: But some of these, and you know, not all of them,
- 21:56Speaker 1: they're you know, there's nothing that gets me going more
- 21:59Speaker 1: than it contained system. And some of these are contained systems,
- 22:03Speaker 1: which is when you have a system that kind of
- 22:05Speaker 1: feeds itself. We talked about these high pressure pumps that
- 22:09Speaker 1: force out what did you call it again, what was
- 22:11Speaker 1: the band? Rejects stream, the reject stream. That's not the
- 22:17Speaker 1: God help you if you call him the reject strange,
- 22:19Speaker 1: that's reject stream. That's like a letterman miss step or something.
- 22:23Speaker 1: And you got a cool logo with just an RN
- 22:25Speaker 1: and S that sort of are snaking around each other
- 22:27Speaker 1: or something like that. This is what I see. Do
- 22:30Speaker 1: you know remember the grateful dead kid with the ice
- 22:33Speaker 1: cream cone on his head? Sure, I remembering along those lines,
- 22:38Speaker 1: But then rather than an ice cream cone, he's got
- 22:40Speaker 1: a reverse mohawk like the bad guy in Death Wish three. See,
- 22:44Speaker 1: I was thinking more like the White Snake logo. Oh no,
- 22:49Speaker 1: it's I don't think so. No, you just blew my
- 22:52Speaker 1: mind a little bit. I'm trying to recover here by
- 22:54Speaker 1: tap dancing. But I don't know, man, maybe not to
- 22:58Speaker 1: get further down this road. But the other day I
- 23:01Speaker 1: saw that there was some big festival in Europe with
- 23:04Speaker 1: all these metal bands, and I was like, oh, looks
- 23:06Speaker 1: kind of cool, and White Snake was playing. I was like,
- 23:08Speaker 1: that was guys still playing. It's like, let's let me
- 23:10Speaker 1: go check them out and see what they sound like.
- 23:13Speaker 1: Just do yourself a favor and go to YouTube and
- 23:15Speaker 1: watch like a White Snake festival from like just like
- 23:19Speaker 1: put In twenty nineteen. Let's say, do they just play
- 23:21Speaker 1: all their old hits? Are they making new music? Oh? Well,
- 23:24Speaker 1: I don't know. I can't speak to that. The old
- 23:26Speaker 1: hits are what's on YouTube. Um, it's not it's not great.
- 23:31Speaker 1: So is it's still okay? You said his name too,
- 23:34Speaker 1: because I almost said David Copperfield. It's great. He makes
- 23:38Speaker 1: the stage disappear beneath his feet. That's right. You forget.
- 23:44Speaker 1: That's the most important part. Yeah, it's it's not great.
- 23:48Speaker 1: It's uh, just just gotta check it out. Boy, This
- 23:51Speaker 1: COVID got you trash and everything. The radium girl, White Snake,
- 23:57Speaker 1: I know, I love White Snake. You know Tanny Containe
- 24:00Speaker 1: passed away. Maybe that's what to do with it? What? Yeah,
- 24:04Speaker 1: she died a couple of years ago. I think I
- 24:06Speaker 1: didn't know that. Yeah, or maybe even last year. No,
- 24:11Speaker 1: I don't know. I'm yeah. Are you on meds right now? No?
- 24:17Speaker 1: High on stuffyheadedness? I got you, you know, the natural high.
- 24:22Speaker 1: So where was I? Oh? Yeah, contained systems. So they're
- 24:24Speaker 1: pumping out this stuff with high pressure, and as we'll see, uh,
- 24:29Speaker 1: that can go just go out into the ocean again
- 24:32Speaker 1: and we'll talk about that more later. But they can
- 24:34Speaker 1: also use that that force of pumping this stuff out
- 24:37Speaker 1: to use it to spin a turbine. Our old friends
- 24:40Speaker 1: spinning a turbine and basically reusing that stuff to to
- 24:44Speaker 1: make it a closed system where it's operating itself. Yeah,
- 24:47Speaker 1: pretty many, amazing. I get jazzed by that as well.
- 24:50Speaker 1: And I just realized, Chuck, basically, these desalination plants that
- 24:55Speaker 1: are close to the ocean are basically a giant YouTube
- 24:59Speaker 1: and in the middle there's that membrane. But really also
- 25:02Speaker 1: in the middle is the the entire desalination plant. But
- 25:05Speaker 1: it's just coming up one side and passing through the other. Actually,
- 25:09Speaker 1: it's not a very good analogy, and I think about it,
- 25:11Speaker 1: but it's a U shape at least, how about that. Yeah,
- 25:15Speaker 1: you can also get him under your sink or on
- 25:17Speaker 1: your countertop in your kitchen. Like it sounds like the
- 25:20Speaker 1: most you know, large scale scientific thing you can imagine.
- 25:23Speaker 1: But if you just go to a big box hardware
- 25:26Speaker 1: store and you look up water filtration systems, a lot
- 25:30Speaker 1: of them are reverse osmosis. Yeah, yeah, you're um, you're
- 25:34Speaker 1: gonna be hard pressed actually to find one that doesn't
- 25:36Speaker 1: have that, Like one of those undersink like multi filter
- 25:39Speaker 1: multi stage water filters that comes with its own faucet
- 25:42Speaker 1: that you have to install, But they don't. I was
- 25:45Speaker 1: looking there actually, you know, um, I think they've actually
- 25:48Speaker 1: come down since this article was written a couple of yeah,
- 25:52Speaker 1: something like that. It seems like you can get a
- 25:54Speaker 1: pretty good one for about two fifty dollars, like basically
- 25:57Speaker 1: everything you need. Yeah, and then there's also own our
- 26:00Speaker 1: top versions two if you want to just have one
- 26:03Speaker 1: on your countertop. But I say, I say we take
- 26:06Speaker 1: a break. Okay, yeah, because we we've talked all upside right,
- 26:11Speaker 1: there's a dark side to this. Well not really, but
- 26:14Speaker 1: you know there's some down downsides of drawbacks. Nothing dark,
- 26:17Speaker 1: I would say that might be overstating it. All right,
- 26:21Speaker 1: Well we'll be back right after this, everybody, Okay, okay, Chuck,
- 26:47Speaker 1: welcome to the dark side of reverse osmosis. Very nice.
- 26:54Speaker 1: You've got compliments on your bellow Legosi. Yeah, it was
- 26:59Speaker 1: very good. I don't remember what episode that was. I'll
- 27:02Speaker 1: take it good. I'll take any compliment. Sure, same here,
- 27:05Speaker 1: unless you're really good at not doing podcasts. Well, yeah,
- 27:11Speaker 1: it took you a second, didn't it it really did.
- 27:13Speaker 1: I think I have sympathetic COVID. I'm a little fogging myself.
- 27:19Speaker 1: You know. You gotta get out of that bunk bed
- 27:20Speaker 1: underneath me. You might catch it. So first, before we
- 27:24Speaker 1: get started, I want to shout out Perth, Australia, Chuck,
- 27:26Speaker 1: get this. Forty three of perth drinking water is made
- 27:31Speaker 1: from desalinated seawater from reverse osmosis. They have two plants
- 27:35Speaker 1: that we probably drank some while we were there. I'll
- 27:38Speaker 1: bet we did. I'll bet we did. I don't know,
- 27:40Speaker 1: it couldn't even tell, so it was right. So do
- 27:47Speaker 1: you know what's funny is everyone outside of Australia got
- 27:50Speaker 1: that joke because I guarantee you they didn't show that
- 27:53Speaker 1: ad in Australia and they also think that Tom Broke
- 27:56Speaker 1: All runs Motel six. That's right. So we're talking about
- 28:02Speaker 1: the dark side of of of reverse osmosis. Plants are
- 28:05Speaker 1: desalinating using reverse osmosis, and reverse osmosis in general, there's
- 28:09Speaker 1: some problems with it. For one, it's really I don't
- 28:14Speaker 1: want to say it's really energy intensive. It's actually not
- 28:16Speaker 1: as bad as you would think. But the more you
- 28:18Speaker 1: scale up and you know where you're supplying say almost
- 28:22Speaker 1: half of your your town's drinking water through reverse osmosis desalination, like,
- 28:28Speaker 1: the energy usage scales up, so the cost can scale up,
- 28:32Speaker 1: and then also so does the carbon footprint of these things,
- 28:36Speaker 1: because you know they're burning fossil fuels to run those
- 28:39Speaker 1: pumps to pressurize that column of water when they send
- 28:42Speaker 1: it across the reverse osmosis membrane to overcome the osmotic pressure.
- 28:46Speaker 1: That's a that's a real big, that's a that's a
- 28:49Speaker 1: problem with it. I guess you could say, yeah, I
- 28:52Speaker 1: would say that. Another problem that we we teased earlier
- 28:55Speaker 1: was the um I guess what do you call it?
- 29:00Speaker 1: Harmful byproduct or just a waste waste byproduct reject stream? Yeah, sure, okay,
- 29:07Speaker 1: but it is it is a byproduct that basically it's salt,
- 29:10Speaker 1: it's brian it is there's a lot of it left over,
- 29:14Speaker 1: and you've got to do something with it if you're
- 29:16Speaker 1: not going to run it back into a closed system.
- 29:18Speaker 1: And some places they just say, all right, well, it's
- 29:21Speaker 1: it's saltwater and very concentrated form, so let's just pump
- 29:24Speaker 1: that back into the ocean. And I'm glad I kept
- 29:28Speaker 1: reading because my first thought was like, I'll sure it's saltwater,
- 29:31Speaker 1: but that can't like the ocean has a certain amount
- 29:33Speaker 1: of salinity on purpose probably and that that can't be
- 29:36Speaker 1: great to just add a lot more. And my instinct
- 29:40Speaker 1: was right, it's not. I think Australian Center for Water
- 29:44Speaker 1: Research says things get back to normal at about sixteen
- 29:50Speaker 1: hundred feet fives from the source. It's pretty pretty far
- 29:55Speaker 1: um so anything within that that sixt feet it's it's
- 29:58Speaker 1: really bad news. When they're up and that stuff back
- 30:00Speaker 1: in and you know it's a fish can get out
- 30:04Speaker 1: of there pretty quickly. But if you're not a fish,
- 30:06Speaker 1: if you're something that crawls along on the sea floor
- 30:08Speaker 1: or plant life on the sea floor, then that's really
- 30:12Speaker 1: bad and it's gonna kill off a lot of stuff
- 30:14Speaker 1: in that area. Yeah, which is problematic. I mean, high
- 30:18Speaker 1: salinity decreases the dissolved oxygen, and fish and sea life
- 30:23Speaker 1: need oxygen in the water, so it's it is a
- 30:25Speaker 1: real problem for that that life that can't move away
- 30:29Speaker 1: very easily. And then in addition to that too, they
- 30:32Speaker 1: actually introduce certain kinds of chemicals and metals into the
- 30:37Speaker 1: um the stream the feeds the feed water stream um
- 30:41Speaker 1: to keep the membranes from fouling up as which happens
- 30:46Speaker 1: really easily. You can imagine if you have a membrane
- 30:50Speaker 1: that has pores that are just big enough to allow
- 30:54Speaker 1: something that's twenty seven hundred thousands of a micrometer a
- 30:58Speaker 1: micron across through, like all that stuff that's left behind
- 31:02Speaker 1: is gonna gunk up the membrane is really quick. It's
- 31:05Speaker 1: going to get insane in the membrane so they take
- 31:07Speaker 1: exactly so they take steps to keep this from fouling,
- 31:11Speaker 1: from getting clogged up by adding additional stuff. Well, that
- 31:14Speaker 1: additional stuff also gets pumped out into the ocean too,
- 31:17Speaker 1: which is a problem as well. There are calls for
- 31:20Speaker 1: um uh additional steps to be added onto that reject
- 31:26Speaker 1: stream so that before it hits the ocean, it runs
- 31:28Speaker 1: through like a UV light that kills off pathogens maybe
- 31:32Speaker 1: UM or maybe they need to filter out some of
- 31:36Speaker 1: the stuff and reuse like the chlorine and the copper
- 31:38Speaker 1: that they're introducing. Um there are things that we could
- 31:41Speaker 1: do to to make the whole thing a little more
- 31:43Speaker 1: environmentally friendly for sure. Yeah for their uh. I think
- 31:48Speaker 1: the plant operators in Australia say that they're like, you're
- 31:52Speaker 1: pumping it out so fast, made it mixes in a
- 31:54Speaker 1: really quick And I don't know if I buy that.
- 31:59Speaker 1: I mean, it makes sense that it mixes faster than
- 32:01Speaker 1: if you're just like leaking it out slowly. But I
- 32:04Speaker 1: would say, just spread it out a lot more if
- 32:06Speaker 1: you could. I mean, maybe that's not practical and it's
- 32:09Speaker 1: just like a a dumb guy who doesn't know how
- 32:11Speaker 1: it works talking, But you know, I would disperse it more. Yeah,
- 32:18Speaker 1: I mean I guess you kind of could. You could
- 32:19Speaker 1: you could put like, ah, like a sprinkler head on
- 32:22Speaker 1: the end, so it's not just one big column. It's
- 32:25Speaker 1: just kind of Ye, it's diffug Just when I thought
- 32:27Speaker 1: it was a dumb idea, No, that's a great idea.
- 32:29Speaker 1: We now we need to go invent like a giant
- 32:31Speaker 1: sprinkler head and patent and use it. Uh. It's not
- 32:36Speaker 1: just a danger for oceans to um. Most of these
- 32:39Speaker 1: plants obviously are near the ocean. Um. But if there
- 32:43Speaker 1: are plants that are more inland and they're storing this
- 32:46Speaker 1: stuff in tanks, you could just like you have an
- 32:49Speaker 1: oil spill, you could have a sailine like a brine spill,
- 32:52Speaker 1: and that would be really really harmful to the dry
- 32:54Speaker 1: land vegetation and plant life and the whole ecosystem. And
- 32:58Speaker 1: you know, I don't think we uh, we kind of
- 33:00Speaker 1: walk past the fact that when you're pumping this stuff
- 33:03Speaker 1: in the sea, it's not just like, oh, some lobsters
- 33:05Speaker 1: and coral dyes, like that's part of the ecosystem that's
- 33:08Speaker 1: going to set off a chain reaction uh to everything
- 33:11Speaker 1: around it as well. Yeah. Um, so there there are
- 33:15Speaker 1: people who are trying to come up with, like we
- 33:17Speaker 1: were saying, like more efficiencies and ways around some of
- 33:20Speaker 1: these problems. One of the things I saw um was
- 33:22Speaker 1: out of the National Laboratory in Idaho, UM that uses
- 33:27Speaker 1: something called switchable polarity solvents. Did you see that. So
- 33:33Speaker 1: there's a different kind of osmosis that they're using that
- 33:35Speaker 1: doesn't require um the artificial pressure built up using pumps
- 33:40Speaker 1: and all that, so automatically it's less energy intensive. And
- 33:43Speaker 1: they added kind of chemical called the switchable polarity solvent,
- 33:48Speaker 1: which when you add it to UM the solution, it
- 33:52Speaker 1: actually raises the osmotic pressure itself, so the water comes
- 33:56Speaker 1: out of solution um on its own without having to
- 34:00Speaker 1: be pressed. And then that switchable polarity solvent comes with it.
- 34:04Speaker 1: You hit it with some heat and it basically shocks
- 34:07Speaker 1: the sps that chemical out of the water UM, and
- 34:10Speaker 1: then you have you've just got your water. And then
- 34:12Speaker 1: you just remove that switchable polarity solvent. So it requires
- 34:16Speaker 1: far less energy, which is a big improvement for sure.
- 34:19Speaker 1: That's pretty amazing it is. And I saw another one
- 34:22Speaker 1: that uses a double piston set up where when they
- 34:26Speaker 1: they do the water treatment basically in batches where they
- 34:30Speaker 1: added to that barrel that has the hollow barrel going
- 34:32Speaker 1: through it with the membrane involved the actual reverse osmosis
- 34:36Speaker 1: filtering on an industrial scale, they added in batches and
- 34:40Speaker 1: they use a piston to push the water through, and
- 34:43Speaker 1: then as the pistons moving, there's another chamber opening up
- 34:46Speaker 1: behind it that's getting filled with sea water. So there's
- 34:49Speaker 1: no downtime where like the piston moves to one side
- 34:52Speaker 1: and then seawater fills up, and then the piston moves
- 34:54Speaker 1: to the other side. It's just constantly going back and forth,
- 34:57Speaker 1: and on either side there seawater that's being treated or
- 34:59Speaker 1: filling up to be treated next, so you don't have downtime.
- 35:02Speaker 1: But then also the sea water that's coming in is
- 35:05Speaker 1: pushing the piston the other way too, so it requires
- 35:08Speaker 1: less energy as well. Um And I think that one's
- 35:11Speaker 1: out of Purdue. So there's some people figuring out how
- 35:14Speaker 1: to make this a little better, less energy intensive, a
- 35:16Speaker 1: little faster um and we'll probably see a lot of
- 35:21Speaker 1: a lot more solutions, especially as water becomes more and
- 35:24Speaker 1: more precious, you know. Starting now. Basically, yeah, they're also
- 35:29Speaker 1: trying to find more uses for that Brian instead of
- 35:31Speaker 1: trying to put it in the ocean. They're like, you know,
- 35:33Speaker 1: surely people can use Brian, right, And there are some
- 35:37Speaker 1: aquaculture applications in commercial aquaculture, I think talapia farms if
- 35:44Speaker 1: you if you like talapia, I'm not a big fan,
- 35:46Speaker 1: but tapia love really I think high high selinic would
- 35:51Speaker 1: that be it? Sure? High selinic water? Sure? I mean
- 35:56Speaker 1: at this point it doesn't matter. Alright, great, they like
- 36:01Speaker 1: really salty water, that's how should salt water, and I
- 36:05Speaker 1: think bream do as well. So they're they're starting to
- 36:08Speaker 1: ship some of that stuff there, and I think, um,
- 36:12Speaker 1: sometimes it can be used to grow stuff like sea
- 36:15Speaker 1: beats or an animal feed or in biofuel. But I
- 36:19Speaker 1: don't think it's like there's still going to be that
- 36:21Speaker 1: byproduct even if they even if every tilapia farm on
- 36:25Speaker 1: Earth wanted this water, you know, this bright stuff. And
- 36:28Speaker 1: especially the more we produce, the more Brian we're gonna have,
- 36:30Speaker 1: because I don't know if we said it or not.
- 36:32Speaker 1: For every one leader of fresh water you produce, you've
- 36:35Speaker 1: got one point five liters of briny water, higher salty
- 36:39Speaker 1: concentration water that you're sending back out to see it
- 36:42Speaker 1: kind of mess with the silin selenic count. So that's
- 36:49Speaker 1: reject streams um first album. What is this selnic sound?
- 36:54Speaker 1: Selnic count reject stream Alright, so Chuck, there's actually we
- 36:58Speaker 1: gotta finish on this one point. There's a debate. Especially
- 37:02Speaker 1: it seems like on Facebook, um is just how healthy
- 37:09Speaker 1: reverse osmosis water is. And in a lot of ways
- 37:12Speaker 1: it makes sense on its face to tell you the truth.
- 37:15Speaker 1: People are like that seems to be the kind of
- 37:20Speaker 1: like the kind of sites that are really touting this
- 37:23Speaker 1: seemed to to have their links promoted on Facebook a
- 37:26Speaker 1: lot um that's as diplomatic as I so. UM. So
- 37:33Speaker 1: the idea is that reverse osmosis is all well and
- 37:35Speaker 1: good for preventing pathogens, viruses, chemicals, minerals, metals from passing through.
- 37:41Speaker 1: And when you run water through reverse osmosis filter, the
- 37:45Speaker 1: ultrapure water you have on the other side is is great.
- 37:49Speaker 1: But the point of these that these people are making
- 37:52Speaker 1: is that it's actually too great, it's too pure, and
- 37:55Speaker 1: that humans actually need more stuff than just hydrogen and
- 38:00Speaker 1: oxygen mixed together, that we need other kinds of like
- 38:03Speaker 1: trace minerals in our water and UM that reverse osmosis
- 38:07Speaker 1: strips it out. So there's this, um, there's remineral remineralization
- 38:12Speaker 1: filters that you can actually get for your reverse osmosis
- 38:16Speaker 1: filter to where it goes through all the stages pre treatment, treatment,
- 38:20Speaker 1: reverse osmosis, and then on the other side, the last
- 38:22Speaker 1: filter is remineralization where it might add a little bit
- 38:25Speaker 1: of boron, a little bit of you know, sea salt,
- 38:28Speaker 1: something like that. Um, it's got a little calcium in it,
- 38:32Speaker 1: and now the water is ultra pure but also beneficial
- 38:36Speaker 1: for your metabolisms, optimal function. It makes a lot of sense.
- 38:39Speaker 1: I didn't see a lot of academic debate over it.
- 38:43Speaker 1: It was happening more peripherally, it seemed like. So that's
- 38:46Speaker 1: why I'm a little a little incredulous of the whole thing.
- 38:48Speaker 1: But it makes a lot of sense. You know, I
- 38:50Speaker 1: like a good mineral water. Yeah. And apparently also if
- 38:54Speaker 1: you um, if you want, if you have reverse osmosis
- 38:56Speaker 1: at your house and you are like, I can't afford
- 38:59Speaker 1: to REMI no realization picture s get yourself a little
- 39:01Speaker 1: Himalayan salt or a little bit sea salt that's more
- 39:06Speaker 1: than just salt, that contains a lot of other um
- 39:09Speaker 1: beneficial elements and um metals, alkali, earth metals and stuff,
- 39:14Speaker 1: and just put a little little sprinkle in there. There
- 39:16Speaker 1: you go, a little taple, do you? That's right? That's
- 39:20Speaker 1: the second album from Reject Stream. They're going pop. They're
- 39:25Speaker 1: like Kings of Leon. They started out kind of edgy,
- 39:27Speaker 1: and then the record company came to call in and
- 39:30Speaker 1: they said, sign us up. I love that first King
- 39:33Speaker 1: of Kings of Leon's album. And then they they said,
- 39:36Speaker 1: all right, hill billy's go get a haircut, yeah, and
- 39:39Speaker 1: get rich. They're like, get hot. Uh, you got anything
- 39:44Speaker 1: else about Kings of Leone? Okay, Well, if you want
- 39:48Speaker 1: to know more about Kings of Leon, rejects, Streame, reverse Osmoses, desalination,
- 39:52Speaker 1: any of that stuff, Um, go check it out on
- 39:56Speaker 1: the internet. See what happens when you search all of
- 39:58Speaker 1: that at once. Maybe the un verse will explode. Since
- 40:01Speaker 1: I said the universe will explode, it's time for a
- 40:03Speaker 1: listener mail. I'm gonna call this conveniently an email from Peth.
- 40:11Speaker 1: Oh wow, isn't it crazy? It's a full circle, man,
- 40:13Speaker 1: that's synchronicity. Uh. I'm not going to read it in
- 40:20Speaker 1: my terrible pasty accent. Though I wish you would, I
- 40:23Speaker 1: can't do it. I'm fading. Hey guys, A big fan
- 40:26Speaker 1: here from far far away Western Australia. My husband and
- 40:29Speaker 1: I spent two years traveling and exploring Australia in a
- 40:32Speaker 1: ute towing a caravan I don't know what that is
- 40:37Speaker 1: sub van truck uh, and in the process discovered the
- 40:42Speaker 1: delights of stuff you should know. It was great for
- 40:44Speaker 1: days with long outback drives. I remember our very first
- 40:48Speaker 1: episode that I randomly selected when we lost our podcast,
- 40:51Speaker 1: Virginity Cave Diving totally nuts and we were hooked. We
- 40:56Speaker 1: have since returned home to our city of Peth because
- 41:00Speaker 1: of COVID put in an abrupt into their travels and
- 41:03Speaker 1: now they listen on their daily drive to and from work. Luckily,
- 41:06Speaker 1: there are so many years worth of shows for me
- 41:09Speaker 1: to catch up on. On our travels, we spent a
- 41:12Speaker 1: week in the outback town of kuber Petty, that is
- 41:16Speaker 1: p E d y c O O b e R
- 41:20Speaker 1: couber Petty, where a lot of worlds of the world's
- 41:23Speaker 1: opals come from. You should do an episode on opals
- 41:26Speaker 1: any who I couldn't help, but notice that you failed
- 41:30Speaker 1: to mention that that town in the Selects Cave Dwelling episode.
- 41:35Speaker 1: I listened to that one recently despite most of the
- 41:37Speaker 1: town living underground and having some beautiful underground churches. Check
- 41:42Speaker 1: it out on Google. Uh, there's another any who. Keep
- 41:46Speaker 1: up the good work. I'll keep listening. Warm wishes that
- 41:50Speaker 1: is from Tamra. Well thanks a lot, Tamara. Any who
- 41:54Speaker 1: appreciate that? Did Tamras spell it h o o or
- 41:58Speaker 1: w h o A and y h o oh? Yeah?
- 42:03Speaker 1: There's two kinds of people in the world, and it's
- 42:04Speaker 1: divided by how you spell any who? There are three
- 42:07Speaker 1: kinds there. You know what the third is what the
- 42:11Speaker 1: people who don't use anything? I don't know, Chuck. I
- 42:14Speaker 1: think we all have a little bit of in any
- 42:16Speaker 1: who user in all of us. I think you're saying
- 42:19Speaker 1: you can take the person out of the any who,
- 42:21Speaker 1: but you can't take the ani who out of the
- 42:22Speaker 1: person you sure said it. Well, thanks again, Tamara, and
- 42:27Speaker 1: shout out to Perth for a third time. Why might
- 42:30Speaker 1: as well make it a hat trick And if you
- 42:32Speaker 1: want your time to get shouted out, why don't you
- 42:34Speaker 1: get in touch with us or build some massive desalination plants.
- 42:37Speaker 1: One of the two that would help a lot. Actually,
- 42:43Speaker 1: you can get in touch with us via email at
