- 0:01Speaker 1: Welcome to Stuff you should know from House Stuff Works
- 0:05Speaker 1: dot com. Hey you welcome to the podcast. I'm Josh Clark.
- 0:14Speaker 1: There's Charles W. Chuck Bryant, guest producer. Noel is here.
- 0:18Speaker 1: Noel's moved in. Yeah, so what that that cod is
- 0:22Speaker 1: on the plan? He works constantly. Uh. You know what
- 0:27Speaker 1: my superhero nickname was as a child. Uh, I'll tell
- 0:33Speaker 1: you plasma Boy. No, it wasn't. I'm just kidding. That
- 0:38Speaker 1: was a weird joke. Why we're talking about plasma Plasma boy? Yeah,
- 0:44Speaker 1: like a radioactive man na plasma boy. Yeah, but it
- 0:49Speaker 1: wasn't plasma boy. It was what was it? What was
- 0:52Speaker 1: the Sidekicks name? Radioactive Man Sidekicks? Uh? Now I want
- 0:59Speaker 1: to know, dude. Well, that's a band, I know, but
- 1:06Speaker 1: I wonder if it's based on that maybe. I don't know.
- 1:10Speaker 1: We'll find out, won't we. Well, we'll look it up
- 1:12Speaker 1: and then we'll find out with a million emails. So, um,
- 1:15Speaker 1: plasma boy. Huh. I wish you must have an affinity
- 1:20Speaker 1: for this episode. Then it's great, Chuck. You know, when
- 1:23Speaker 1: lightning strikes the earth, we did a pretty awesome podcast
- 1:28Speaker 1: on lightning. Do you remember we talked about how it
- 1:31Speaker 1: literally rips the sky open. It rips the atmosphere open,
- 1:38Speaker 1: and as it's traveling down through this ripped open atmosphere,
- 1:41Speaker 1: the air on either side of this stuff is superheated
- 1:44Speaker 1: to about twenty thousand degrees. It's more than three times
- 1:48Speaker 1: the surface temperature of the sun celsius. I should say celsius,
- 1:53Speaker 1: not even fair enhog. It's about twelve grand celsius. Roughly,
- 1:57Speaker 1: it's super hot, right, I'm sorry. Fare Kneite does a
- 2:00Speaker 1: fare kneit. Yeah, twelve grand fare kneit. Yeah, Okay. At
- 2:05Speaker 1: any rate degrees is lightning. And this when the air
- 2:10Speaker 1: is superheated, it takes on what's commonly called the fourth
- 2:13Speaker 1: state of matter, plasma. Right, so you've got solid, boring
- 2:19Speaker 1: liquid gas. Awesome, Okay, but plasma is super awesome gas.
- 2:26Speaker 1: It's it's a bit like a gas, and usually it
- 2:29Speaker 1: starts out as a gas, but it it holds an
- 2:33Speaker 1: electro magnetic field, or creates an electromagnetic field, and it
- 2:38Speaker 1: holds an electrical charge. It has free roaming electrons. It's
- 2:41Speaker 1: running through it doing all sorts of crazy stuff. It
- 2:44Speaker 1: just basically breaks gas into like this, this crazy, weird
- 2:49Speaker 1: different type of fluid and that's plasma and it's awesome
- 2:54Speaker 1: ionized gas. Yes, pretty good stuff. Uh, super high tempts,
- 2:59Speaker 1: like you are saying. And because it's a super high attempt,
- 3:03Speaker 1: what it can do is it it can break down,
- 3:06Speaker 1: it can it can it can cause something solid to
- 3:09Speaker 1: undergo what's called molecular dissociation, which means it's not just
- 3:14Speaker 1: burning something, it's not melting something. It's actually exposing it
- 3:19Speaker 1: to so much heat that the molecular bonds break apart
- 3:23Speaker 1: and it becomes a pile of its components and it
- 3:29Speaker 1: breaks it down to from its compound of molecules to
- 3:33Speaker 1: its atomic components. Yeah, pretty amazing. It is very amazing. UM.
- 3:38Speaker 1: And it's like you said, it's not it's not UM
- 3:40Speaker 1: burning Like this process of UM using a plasma torch
- 3:47Speaker 1: to break something down to decompose it is actually what
- 3:50Speaker 1: it's doing. UM doesn't even need to use oxygen nope. UM.
- 3:55Speaker 1: So that means that it's a process called pyrolysis, which
- 4:00Speaker 1: is intense, intense heat that creates decomposition in some sort
- 4:04Speaker 1: of matter, especially organic matter, and UM. As a result,
- 4:07Speaker 1: you get these byproducts. If it's a an organic piece
- 4:12Speaker 1: of materials, say like some corn stalks that are using
- 4:15Speaker 1: a biomass feedstock. Um, it will become something called sin gas. Right.
- 4:21Speaker 1: And then if it's something like um old pair of
- 4:27Speaker 1: roller skates, yeah, we'll save those. First of all, they're
- 4:32Speaker 1: just not very good any longer. So the leather is
- 4:37Speaker 1: was it at one point organic? I guess it would
- 4:39Speaker 1: still be considered an organic material that turns into gas.
- 4:42Speaker 1: The metal in the skates that will turn into something
- 4:47Speaker 1: called slag, right, and it undergoes the process of vitrification, Yeah,
- 4:53Speaker 1: it does. Vitrification is where this stuff becomes so the
- 4:58Speaker 1: bombs break between it so thoroughly that it becomes basically
- 5:02Speaker 1: a form of glass, yeah, like volcanic glass, almost at
- 5:06Speaker 1: least what it looks like, Yeah, like obsidient. So all
- 5:10Speaker 1: this sounds great. We're kind of beating around the bush
- 5:13Speaker 1: about what a plasma torch can do. Um, And here's
- 5:18Speaker 1: the big, the big bomb boom. Plasma torches can burn
- 5:23Speaker 1: garbage and waste. Yes. And not only that, they can
- 5:27Speaker 1: burn it without combustion, which means there's not a bunch
- 5:30Speaker 1: of smoke. Yeah, and they can actually harvest the energy
- 5:35Speaker 1: in that garbage in incredible ways because it turns out
- 5:40Speaker 1: garbage is chock full of potential energy. You can release
- 5:45Speaker 1: that energy when you burn it, like just regular incineration,
- 5:48Speaker 1: but you only can maybe net about fift of the
- 5:53Speaker 1: energy that's locked into this big pile of garbage in
- 5:56Speaker 1: like a landfill, right, what a waste. With using a
- 5:59Speaker 1: plast the torch to create pyrolysis or gasification, you can
- 6:04Speaker 1: net up to eight of that energy that's locked in
- 6:08Speaker 1: their potentially crazy into garbage. So what we're talking about
- 6:11Speaker 1: is a potential future where we are using plasma torches
- 6:15Speaker 1: to create energy to sell back to the grid, to
- 6:19Speaker 1: create steam to turn those turbines, like we're always still
- 6:23Speaker 1: just knocked out that that's how you create energy these days,
- 6:26Speaker 1: I'm sorry electricity. Uh, and then sell off byproducts as
- 6:31Speaker 1: well and make more money. Yes, it's it's like I
- 6:34Speaker 1: cannot be more excited about this. And medical waste, chemical waste,
- 6:41Speaker 1: throw it in there. In fact, you know what, so
- 6:44Speaker 1: anything you got in their daddy, except for like radioactive material,
- 6:50Speaker 1: you gotta you gotta swine flu outbreak. Take those pig carcasses,
- 6:54Speaker 1: you throw them into the gasification chamber. There is no
- 6:59Speaker 1: swine flu left. It is totally gone. Or how about this.
- 7:03Speaker 1: I'll bring it to your farm. I'll have a small
- 7:05Speaker 1: one set up. You got a swine food outbreak, I'll
- 7:07Speaker 1: come to your farm and I'll burn up all those
- 7:10Speaker 1: nasty pigs. You've got some toxic waste. Oh well, we'll
- 7:14Speaker 1: just burn that in a gasification chamber and we'll break
- 7:18Speaker 1: it down to its innert components. It's not gonna hurt anybody,
- 7:21Speaker 1: no more, little lamb. I guess we keep saying burn. Well,
- 7:25Speaker 1: it's really tough not to ye to see torch torch. Yeah. Nice,
- 7:31Speaker 1: all right, So let's talk. Strickland wrote this, Jonathan Strickland
- 7:34Speaker 1: of Tech Stuff, and he did a great job and
- 7:38Speaker 1: he seemed to be as excited about it as we
- 7:41Speaker 1: are when he was writing it, because how can you
- 7:43Speaker 1: not be. Uh, Let's talk about some of the parts
- 7:47Speaker 1: of these things. The first thing that he points out
- 7:49Speaker 1: that we should point out is that um any plasma
- 7:54Speaker 1: conversion gasification facility is gonna be unique to its own knee.
- 8:00Speaker 1: They're all custom built at this point, there's no standardized unit.
- 8:04Speaker 1: There are some companies that are starting to like westing
- 8:07Speaker 1: House has some that you can just like what amounts
- 8:11Speaker 1: to off the shelf. The backyard gasifier pretty much. Yeah,
- 8:15Speaker 1: they I think they have like three different models, although
- 8:16Speaker 1: I'm sure they will custom build you whatever you want.
- 8:19Speaker 1: You're probably right. Uh But anyway, when he wrote this,
- 8:23Speaker 1: they weren't super standardized, and that's good that we're going
- 8:25Speaker 1: towards that. But um so what we're gonna talk about it,
- 8:28Speaker 1: you know, sort of depends on the system. But what
- 8:31Speaker 1: you're probably gonna have is conveyor belt that's gonna move
- 8:33Speaker 1: the garbage into the converter. Yeah, it's gonna play that
- 8:37Speaker 1: Bugs Bunny Powerhouse song. Oh man. Sometimes they will pre
- 8:42Speaker 1: treat the stuff like although you could, if you had
- 8:45Speaker 1: a big enough um machine, you could throw an entire
- 8:49Speaker 1: car in it, let's say, but sometimes it's more efficient
- 8:52Speaker 1: to break that car down and have a pilot, tires
- 8:54Speaker 1: and a pile of scrap metal and break it down
- 8:57Speaker 1: to its components, just to make it more efficient. Yeah,
- 8:59Speaker 1: because it's gonna use a lot less energy to break
- 9:01Speaker 1: it down into smaller parts and then feeded into the
- 9:05Speaker 1: the plasma torch incinerator. Then it will to just torch
- 9:10Speaker 1: it with the torch because these things use a lot
- 9:13Speaker 1: of energy, a lot of energy. They probably saved that
- 9:17Speaker 1: for when the investors come by right there like watching
- 9:21Speaker 1: now you see it? Now you don't. Uh, you have
- 9:24Speaker 1: your furnace, of course, and Strickland says, this is where
- 9:27Speaker 1: the magic happens um because you don't need oxygen. It
- 9:30Speaker 1: is air locked and airtight. Um junk goes in, but
- 9:36Speaker 1: the heat doesn't escape into the atmosphere or the gases
- 9:39Speaker 1: or the byproducts, which again that is really saying something
- 9:42Speaker 1: about the material science that's gone into this, because these
- 9:46Speaker 1: things are burning it like or heated to six thousand
- 9:49Speaker 1: degrees fahrenheigh again celsius, like the temperature of the sun
- 9:55Speaker 1: in this little in this canister right here. It's amazing.
- 9:59Speaker 1: I'm surprised plasma weapons for real. I think it's really
- 10:02Speaker 1: great that they don't. I looked into it. It's like
- 10:05Speaker 1: the realm of video games of course, like plasma guns
- 10:07Speaker 1: and stuff. Uh So, if you have a furnace, which
- 10:12Speaker 1: you will, you're gonna have the plasma torch, which is
- 10:15Speaker 1: in the lower like half of the furnace, let's say.
- 10:18Speaker 1: And they're also gonna have some drainage for that slag
- 10:20Speaker 1: and some venting for the gas, and it's going to
- 10:23Speaker 1: be water cooled. Yeah. One of the things that came
- 10:26Speaker 1: across to me and this researching this is these things
- 10:30Speaker 1: frequently have like really elegant designs. Right, So, like you
- 10:33Speaker 1: have a drain for the slag, which again is the
- 10:35Speaker 1: molten metal that's broken down to like it's constituent parts.
- 10:39Speaker 1: It's inorganic material and depending on how you treat it
- 10:42Speaker 1: will turn into glass or sand or nodules right asphalt um.
- 10:47Speaker 1: And then you have the gas going up, but you
- 10:50Speaker 1: also and you're draining off the slag, but you're also
- 10:53Speaker 1: keeping some in because it forms basically a coke bed
- 10:57Speaker 1: that keeps the furnace hot, which you have to use
- 11:00Speaker 1: less energy in your in your plasma torch, just like
- 11:05Speaker 1: having your own little lava bed just sort of sitting
- 11:07Speaker 1: there up. So that's pretty cool, but eventually you're gonna
- 11:11Speaker 1: probably want to get some of the slag out of
- 11:13Speaker 1: there because you're gonna do cool things with it, which
- 11:15Speaker 1: we'll talk about later. The plasma torch as themselves are clever,
- 11:18Speaker 1: amazing little instruments. It's basically a uh it's a lightning creator,
- 11:26Speaker 1: like they use an electrical arc. They push usually just
- 11:29Speaker 1: plain old air through it so that this electric charge
- 11:33Speaker 1: heats the air to these six thousand degrees, turns it
- 11:36Speaker 1: into plasma and then that's what's directed into the furnace.
- 11:41Speaker 1: It is very crazy, but that's that's what they're doing.
- 11:44Speaker 1: It's a little water cooled torch that that gets super hot.
- 11:48Speaker 1: Also doesn't use any kind of oxygen for combustion. Right.
- 11:52Speaker 1: And also these things you want to turn me on
- 11:56Speaker 1: with electrical stuff is show me a system that powers self,
- 12:01Speaker 1: right that I just love that more than anything in
- 12:03Speaker 1: these facilities, Um, I mean they've got they've got excess
- 12:08Speaker 1: energy to spare afterwards, not only can they power themselves
- 12:11Speaker 1: in a lot of cases, they're selling uh back to
- 12:14Speaker 1: the grid. Right. So, once you've got this initial input
- 12:17Speaker 1: where you get this thing going online and you heat
- 12:20Speaker 1: that plasma torch up for the first time, the moment
- 12:23Speaker 1: you start feeding feedstock into it, which in this case
- 12:26Speaker 1: is garbage plain old municipal solid waste from their lands
- 12:29Speaker 1: back to the future. Right, Um, Right, when you start
- 12:33Speaker 1: feeding that, it starts to produce energy. And the way
- 12:36Speaker 1: that it does that that gas that escapes sing Gaess,
- 12:40Speaker 1: let's talk about sing gas, dude. Sincas is a beautiful, amazing,
- 12:44Speaker 1: elegant thing. It has, it's combustible and it's untreated form,
- 12:50Speaker 1: so you could use it to burn like natural gas,
- 12:52Speaker 1: although it has about half the energy density of natural gas.
- 12:56Speaker 1: But if you're burning um garbage, it's just basically free
- 13:00Speaker 1: natural gas. The byproduct you can also treat it and
- 13:03Speaker 1: scrub it and just release it into the atmosphere is
- 13:06Speaker 1: innert gas. No problems with that water water scrubbed, right.
- 13:11Speaker 1: But when the sing gas exits the furnace, it's it
- 13:17Speaker 1: wants to expand. So if you're a very clever engineer,
- 13:20Speaker 1: you'll put what's called the gas turbine right there. A
- 13:23Speaker 1: gas turbine is spun by expanding gas. Well, you've got
- 13:27Speaker 1: plenty of that stuff, right, So you've got the sing
- 13:29Speaker 1: gas going through the gas turbine spinning that so it's
- 13:32Speaker 1: a generating electricity. It's also very hot, so once it
- 13:36Speaker 1: goes through that gas turbine, it can be caught by
- 13:39Speaker 1: what's called a heat recovery steam generator, right, And that's
- 13:43Speaker 1: just got some water going through it and it uses
- 13:44Speaker 1: hot this hot heat gas to turn the water into steam. Well,
- 13:50Speaker 1: that in turn turns another turbine. It generates even more electricity,
- 13:54Speaker 1: and then at the end, before you even treat it,
- 13:56Speaker 1: you have all the sin gas that could be used
- 13:58Speaker 1: to fuel a austion engine to generate even more electricity,
- 14:03Speaker 1: all from burning garbage. All right, we have to take
- 14:07Speaker 1: a break because I have to peel Josh off the
- 14:09Speaker 1: ceiling because you're so excited about sin gas. All right,
- 14:13Speaker 1: we'll be back in a second. How you feeling, buddy,
- 14:39Speaker 1: He okay, I'm so excited. This might as well be
- 14:43Speaker 1: ocean currents. Oh yeah, you like that one too, huh.
- 14:47Speaker 1: All right, so we're talking about sin gas. You need
- 14:49Speaker 1: to scrub it with water. They passes through a spray
- 14:53Speaker 1: of water. You're actually cleaning gas, which is pretty interesting
- 14:56Speaker 1: as a concept. And then there are all measure of
- 14:58Speaker 1: filters after word, to remove acids and things like that
- 15:04Speaker 1: which do form weird byproducts like salts and salts. It's
- 15:09Speaker 1: pretty neat. If you run it through a base scrubber,
- 15:11Speaker 1: it turns into salts. But there again inert like just
- 15:14Speaker 1: go ahead, pick up a handful and eat it. See
- 15:16Speaker 1: what happens? Probably nothing. And if you use an afterburner,
- 15:20Speaker 1: sometimes they'll use a secondary burner, uh, which is actually
- 15:24Speaker 1: just natural gas flames. I guess to finish the job.
- 15:27Speaker 1: Maybe yeah, to burn off like any particulate matter in
- 15:31Speaker 1: the gas, like if the if them, the process didn't
- 15:37Speaker 1: the sing gas isn't like pure this This basically burns
- 15:41Speaker 1: off particular matter. Or you can scrub it too. And
- 15:44Speaker 1: if you're doing all this, you're probably just going to
- 15:46Speaker 1: release it rather than try to trap it and use
- 15:48Speaker 1: it for combustion if you're gonna scrub it. But you
- 15:51Speaker 1: do need to scrub it, especially if you're gonna release
- 15:53Speaker 1: in the atmosphere, because it does contain some pretty nasty
- 15:56Speaker 1: stuff cabium, mercury, a lot of heavy metals. Because remember
- 16:01Speaker 1: what what this process does. The plasma torch and the
- 16:04Speaker 1: gasification process breaks these things down into the their constituent
- 16:09Speaker 1: um atoms and molecules and heavy metals and and um.
- 16:15Speaker 1: Some other things are not really good for us, even
- 16:18Speaker 1: in their most basic form. So for the most part,
- 16:20Speaker 1: it's gonna take something that chemically speaking, was once a
- 16:25Speaker 1: threat but has been broken down to its separate, innocuous
- 16:28Speaker 1: in our components. Some things, even when they're at their
- 16:31Speaker 1: most basic level, are still dangerous to us, like cadmium,
- 16:34Speaker 1: like mercury, like other heavy metals, and these things do
- 16:37Speaker 1: have to be taken out of the slag and or
- 16:41Speaker 1: the sin gas and disposed of. The thing is is,
- 16:45Speaker 1: if you put a thousand tons of municipal solid waste
- 16:48Speaker 1: into one of these furnaces, you're only gonna get about
- 16:53Speaker 1: twenty tons of that stuff. So so we will still
- 16:58Speaker 1: need landfills or something like that, but it will just
- 17:00Speaker 1: be for these very um dangerous chemicals are very dangerous,
- 17:04Speaker 1: like heavy metals or something like that. But you still
- 17:07Speaker 1: got great stuff out of the other nine times. Yeah, exactly.
- 17:13Speaker 1: So the byproducts we talked about, the sing gash, the slag,
- 17:17Speaker 1: and the heat are all used or not always used,
- 17:20Speaker 1: depends on what you're trying to do with your plant,
- 17:22Speaker 1: but they can potentially all be used. And the slag,
- 17:27Speaker 1: I think you already said you're getting. So that means
- 17:29Speaker 1: the weight of your resulting slag is only of what
- 17:33Speaker 1: you started with. So you took that buick, uh, and
- 17:37Speaker 1: it now weighs what it formally weighed. You could pick
- 17:41Speaker 1: it up if you wanted, Yeah, maybe, so, probably should
- 17:44Speaker 1: wait for it to cool down. And the volume is
- 17:47Speaker 1: only about five percent of the original waste volume. Uh.
- 17:50Speaker 1: And like you said, it looks like volcanic glass, and
- 17:53Speaker 1: they can use it in asphalt and concrete. They can
- 17:56Speaker 1: pour it directly into molds and make paper stones, and
- 18:00Speaker 1: it's all of a sudden, it's a it's a it's
- 18:03Speaker 1: something that you would find at your Big Bucks hardware
- 18:06Speaker 1: store for your garden, which is pretty amazing. Another UM
- 18:09Speaker 1: potential creation that you can use slag for is to
- 18:12Speaker 1: turn into rock wool. Man, I love this stuff right like,
- 18:16Speaker 1: so as the smolten slag is coming out, if you
- 18:18Speaker 1: expose it to compressed air blasts, it turns into this
- 18:22Speaker 1: thready very light but also very strong wool type material
- 18:27Speaker 1: like gray cotton candy. Is how um how Strickland puts it.
- 18:31Speaker 1: And there's a lot of uses for it, Like you
- 18:33Speaker 1: can use it in hydroponics. It's a it's a growing medium. UM.
- 18:38Speaker 1: You can also use it as insulation. Apparently it has
- 18:41Speaker 1: twice the insulating properties of UM fibery last. Yeah, it
- 18:47Speaker 1: is UM and you can also use the clean up
- 18:50Speaker 1: oil spills. That says, Yeah, this is the one that
- 18:52Speaker 1: really gets me going. It's lighter than water, so you
- 18:54Speaker 1: can just throw it on water and it'll sit there
- 18:57Speaker 1: and it's super absorbent, so it'll basicly, what they'll probably
- 19:02Speaker 1: do is contain it in something like a tube or
- 19:05Speaker 1: something and then just throw that tube in a big
- 19:08Speaker 1: circle around an oil spill. It'll float on the water
- 19:11Speaker 1: soak up the oil. Um, you just go back and
- 19:14Speaker 1: scoop up the Rockwell, yeah, I guess. So. I had
- 19:18Speaker 1: a friend that used to work and um, I need
- 19:21Speaker 1: to look that up and him up actually, because I
- 19:23Speaker 1: don't know where it went. But they were using banana
- 19:26Speaker 1: fibers to do the same thing to clean up oil spills.
- 19:31Speaker 1: Didn't we do one on oil spills? And like your friend,
- 19:34Speaker 1: you emailed with them or something like that about it.
- 19:37Speaker 1: I don't know, I feel like we did. It seems
- 19:38Speaker 1: like the distant past. But here's the cool thing about
- 19:41Speaker 1: the the rock will they currently use it. It's not
- 19:45Speaker 1: just something that you can only get as a byproduct
- 19:48Speaker 1: of creating the sin gas. It is produced by mining rocks.
- 19:53Speaker 1: You melt it down and then spin it sort of
- 19:55Speaker 1: like cotton candy, like you said, in a big machine.
- 19:59Speaker 1: And here's the cool thing about the gasification though. The
- 20:02Speaker 1: way they make the rock will now it's about ten
- 20:05Speaker 1: cents I'm sorry about a dollar a pound as a
- 20:08Speaker 1: byproduct That could be sold for ten cents a pound plus.
- 20:11Speaker 1: You don't have all of the um the disturbances in
- 20:15Speaker 1: the earth of mining rocks to turning the rock will
- 20:18Speaker 1: it's a byproduct of garbage that you're burning. That's great,
- 20:21Speaker 1: it's amazing. This is like when win win win win,
- 20:25Speaker 1: win win win. The slag is not leachable. That's another
- 20:29Speaker 1: cool thing that I found too. So Strickland specifically said,
- 20:32Speaker 1: you can't do this with radioactive material. I have seen
- 20:35Speaker 1: that you can. Yeah, And what you can do is
- 20:40Speaker 1: it'll turn it into the slag the subsidian glass, and
- 20:44Speaker 1: while it's still radioactive, it's not going anywhere. It's not
- 20:48Speaker 1: going to leach out into the soil, and it shall.
- 20:51Speaker 1: It should be stable like this for thousands of years,
- 20:54Speaker 1: conceivably until the radioactivity is not harmful the humans any longer.
- 20:59Speaker 1: It would be a really great You can just turn
- 21:01Speaker 1: it into these radioactive paver stones that yeah, that might
- 21:06Speaker 1: even glow at night. You'd have a nice little path
- 21:08Speaker 1: in your backyard and they'll glow. There's actually glass like that.
- 21:12Speaker 1: I can't remember what it's technical term is, but in
- 21:16Speaker 1: the mid twentieth century there was a big trend for
- 21:20Speaker 1: radio They called it vasoline glass because it glowed about
- 21:24Speaker 1: the color of vasoline, which is weird. But you can
- 21:27Speaker 1: find cut glass like ashtrays and sculptures that glow, and
- 21:30Speaker 1: the reason they glow because they're radioactive. I think, I
- 21:34Speaker 1: know what you're talking about, really neat looking, but it's
- 21:36Speaker 1: also like, I don't know if that should be in
- 21:38Speaker 1: my home. I would like your own cigarette holds. All right. Uh, well,
- 21:44Speaker 1: let's take another break here and we'll talk about where
- 21:47Speaker 1: we are now and where we could be headed with gasification.
- 22:13Speaker 1: All right, So here's what I've found in this might
- 22:17Speaker 1: not even be current. What I saw was that they're
- 22:20Speaker 1: currently eight functioning plasma gasification facilities in the world. That's
- 22:27Speaker 1: that sounds about right. One in Taiwan, when in Japan,
- 22:30Speaker 1: one in Canada, when in England, one here in the USA.
- 22:33Speaker 1: Where's the one in the US? Uh think Vero Beach, Florida.
- 22:37Speaker 1: Oh yeah, um, one in India, one in China, and
- 22:40Speaker 1: get this one, there's one on an aircraft carrier that
- 22:44Speaker 1: the US is using. The idea is that it's a
- 22:49Speaker 1: little small unit that basically just treats the on board waste.
- 22:55Speaker 1: So they envisioned the future where like cruise ships have
- 22:58Speaker 1: these things, and they don't have just dump all their
- 23:01Speaker 1: garbage in the ocean, while there's exactly you treat all
- 23:04Speaker 1: the waste, and I guess they could even sell buy
- 23:06Speaker 1: products that they wanted to. UM. There's one that's supposedly going.
- 23:12Speaker 1: I know you saw it was mothballed, right, But there's
- 23:15Speaker 1: one that's that's playing. They have like all the I
- 23:18Speaker 1: guess the UM licenses and certifications that they need to
- 23:22Speaker 1: build one in Port St. Lucy, Florida. And it's supposedly
- 23:27Speaker 1: it started out um as it was going to take
- 23:30Speaker 1: on a thousand tons of garbage a day and put
- 23:33Speaker 1: out UM third, it was gonna generate sixty seven megawatt
- 23:38Speaker 1: hours a day and sell thirty three of that, so
- 23:43Speaker 1: it would completely power its own operations and still have
- 23:46Speaker 1: thirty three megawatt hours to put out, like to sell
- 23:49Speaker 1: back to the grid. It's just more money that this
- 23:52Speaker 1: thing is making, right, UM. What I saw is that,
- 23:55Speaker 1: and I think it was like two thousand, fourteen UM.
- 23:58Speaker 1: It said that it was going to be about six
- 24:01Speaker 1: of that, so it would take in about six hundred
- 24:03Speaker 1: tons of garbage and generate a total output of twenty
- 24:07Speaker 1: two mega OTTs um but yeah, I don't know if
- 24:12Speaker 1: it's coming or not. But either way, the thing that
- 24:15Speaker 1: got me about this one, chuck, was that they planned
- 24:18Speaker 1: to not just accept landfill waste, but to go out
- 24:22Speaker 1: and mind existing landfills and use those things as feedstock.
- 24:27Speaker 1: And in fact, there was one in um uh Uashinai,
- 24:32Speaker 1: Japan that closed down because they ran out of feedstock.
- 24:35Speaker 1: They burned through all the garbage. Wo. Yeah, that's pretty
- 24:39Speaker 1: great when you're out of garbage exactly. They'll stop earlier
- 24:45Speaker 1: this year, I think um the world's largest plant um is.
- 24:49Speaker 1: They said it was near completion in May, so it
- 24:50Speaker 1: may be done at this point. But a company called
- 24:53Speaker 1: Air Products UM began processing three d and fifty thou
- 24:58Speaker 1: tons at this facility, creating power. Wow wait during tons. Yeah,
- 25:05Speaker 1: it's had enough powered for homes and uh fifty full
- 25:10Speaker 1: time jobs, which is not that many, not for that much,
- 25:14Speaker 1: but no, which is highly automated, I would guess, yeah,
- 25:16Speaker 1: which is sort of good in a way. Um, but
- 25:19Speaker 1: I guess you'd want more jobs created to this is
- 25:22Speaker 1: sort of a balancing acting, guess. Uh. And it costs
- 25:25Speaker 1: half a billion, five million dollars um and that is
- 25:30Speaker 1: one of the that's one of the stumbling blocks along
- 25:33Speaker 1: the way. Strickland points out that anytime you have a
- 25:35Speaker 1: new technology, it's gonna be super expensive to get going.
- 25:38Speaker 1: And everyone's dug in on the landfill and how we're
- 25:41Speaker 1: doing things now, so it's gonna take a lot. It'll
- 25:44Speaker 1: get cheaper over time like everything else. That's a new
- 25:48Speaker 1: new way of doing things. And you also have to
- 25:50Speaker 1: win over the establishment with with dollars. You have to
- 25:54Speaker 1: show them why it'll be better for them financially. Well. Yeah. Also,
- 25:58Speaker 1: if if say a municipality is kind of like, well,
- 26:02Speaker 1: we're not gonna close down the landfill, but if you
- 26:05Speaker 1: guys want to open one, go ahead. Well then you
- 26:07Speaker 1: have a plasma waste treatment facility and a landfill in
- 26:12Speaker 1: direct competition. And if you are their customer, meaning you
- 26:16Speaker 1: have some garbage that you want to take, you don't
- 26:18Speaker 1: care where your garbage is going, probably you want to
- 26:21Speaker 1: go to whoever has the cheaper fees for accepting that garbage.
- 26:25Speaker 1: Because a landfill is kind of an expensive proposition. They're
- 26:29Speaker 1: tipping fees are going to be high. It's basically the
- 26:31Speaker 1: only way they can make money if by charging people
- 26:34Speaker 1: to deposit their garbage with a plasma waste treatment facility,
- 26:39Speaker 1: They're making money all over the place. They're selling slag
- 26:42Speaker 1: as paper stuff, they're selling rockwell to clean up oil spills,
- 26:47Speaker 1: they're selling electricity back to the grid. So they're making
- 26:50Speaker 1: money in all these other ways that can pay for
- 26:52Speaker 1: the operation and generate a profit so they could keep
- 26:55Speaker 1: their tipping fees low. So if you own a landfill
- 26:58Speaker 1: and somebody opens a plasma waste tream facility in the
- 27:00Speaker 1: same city, you may be in a bit of trouble
- 27:03Speaker 1: business wise. Yeah, keep the tipping philo and uh and
- 27:07Speaker 1: not just people like municipalities will begin using your services ultimately,
- 27:11Speaker 1: because I think the one thing that's lacking still is
- 27:14Speaker 1: that environmental will right, And we're definitely a lot further
- 27:18Speaker 1: along than we were when Strickland wrote this article. But
- 27:22Speaker 1: I think that that that's one of the things that
- 27:23Speaker 1: makes it so attractive is we're gonna burn your garbage
- 27:27Speaker 1: and really really green sustainable ways create energy from it.
- 27:31Speaker 1: And we're gonna go get your old garbage and burn
- 27:34Speaker 1: that too and make even more electricity, and the plant's
- 27:38Speaker 1: gonna power itself with your garbage. It's it's a win
- 27:41Speaker 1: win win win Win Win So Strickland interviewed, Um he
- 27:48Speaker 1: was from Georgia Tech, right, a doctor Cisero. I'm sorry
- 27:52Speaker 1: cerci Cercio. Oh I thought it was Cistero too. Yeah,
- 27:56Speaker 1: it's a mine trick are before? See? Um? So Dr
- 28:01Speaker 1: Cercio said he envisions a future where you don't just
- 28:05Speaker 1: have like the big municipality plant, Like that'd be great
- 28:08Speaker 1: and all. Maybe you could bring a plasma torch to
- 28:12Speaker 1: a landfill and just bore a hole through it and
- 28:16Speaker 1: stick that plasma torch in there, cap it off, and
- 28:19Speaker 1: start burning that junk from the inside out. Yeah, but
- 28:22Speaker 1: I feel like, well, whoa, whoa, there could be a
- 28:24Speaker 1: coal steam nearby. What about what I thought? What about? Like,
- 28:27Speaker 1: uh what Centralia, Pennsylvania. Right, Centralia, Pennsylvania caught fire. There's
- 28:35Speaker 1: a combustion fire going on. If any coal steam was
- 28:39Speaker 1: exposed to this, it would it would just be decomposed
- 28:42Speaker 1: into carbon into its constituents. It wouldn't catch fire. That's
- 28:46Speaker 1: nothing to do with this again. So it's actually extremely
- 28:50Speaker 1: safe and the landfill itself would act as the furnace.
- 28:54Speaker 1: That's amazing, isn't it. Like it's really tough to think of,
- 28:57Speaker 1: really intense heat without thinking fire. But that that is
- 29:02Speaker 1: not where this goes. Uh or Dr Sir Sero cercio
- 29:10Speaker 1: Ceo says, hey, why not work together here and bring
- 29:17Speaker 1: a plasma converter to another existing traditional facility where they
- 29:23Speaker 1: can work hand in hand, like a coal fire power plant. Yeah,
- 29:25Speaker 1: why not? So what this would do is you would
- 29:28Speaker 1: just basically stick a plasma facility onto it into the
- 29:32Speaker 1: existing infrastructure and just accept garbage in there and burn
- 29:36Speaker 1: that and everything, and then the sin gas that's created
- 29:39Speaker 1: would be used to help fire the coal fire plants.
- 29:43Speaker 1: Then it would be used for combustion, right, and you
- 29:46Speaker 1: would be using less coal or less fossil fuels to
- 29:49Speaker 1: UM do the same thing to create steam to spin
- 29:52Speaker 1: the turbine, because ultimately that's what it all comes down
- 29:55Speaker 1: to with electricity. So if you have a UM a
- 29:59Speaker 1: green way to supplement the stuff, all you're doing is
- 30:02Speaker 1: using less fossil fuel too. It's also way cheaper because
- 30:06Speaker 1: then you're not having to treat the sin gas, which
- 30:09Speaker 1: apparently is half the cost of a plasma treatment facili
- 30:13Speaker 1: because these guys have to treat the escaping smoke and
- 30:16Speaker 1: everything anyway. So all you're doing is adding actually a
- 30:19Speaker 1: cleaner um, a cleaner fuel into the fire. It's going
- 30:23Speaker 1: to ultimately be cleaned down the line. Amazing. And then
- 30:27Speaker 1: we talked about um sort of half joking, but they're
- 30:30Speaker 1: serious about decontamination. You know, if you have an outbreak
- 30:34Speaker 1: on your farm and you have a bunch of uh,
- 30:37Speaker 1: you know, sad. But if you have a bunch of sick,
- 30:40Speaker 1: disease dead livestock, just bring out the h the P
- 30:45Speaker 1: three thousand, throw those cows in there, bing bang boom. Yeah,
- 30:50Speaker 1: maybe grind them up first two yeah, why not? Um? Yeah,
- 30:54Speaker 1: and you can do that with soil as well. Contaminated soil,
- 30:57Speaker 1: got an e. Coli outbreak and your spinach field not anymore,
- 31:02Speaker 1: But the dirty humans not anymore. Storm in there, medical
- 31:05Speaker 1: waste to biohezard. Nope, you've got inert stuff, poopy cruise ship,
- 31:11Speaker 1: the whole thing in there at once. I'm kidding about
- 31:14Speaker 1: dirty humans. By the way, why do I didn't even
- 31:17Speaker 1: need to say that. I don't think so. I hope not.
- 31:22Speaker 1: You never know, buddy. So that is plasma waste treatment,
- 31:26Speaker 1: hopefully the wave of the future. Yeah, we should title
- 31:29Speaker 1: this something a little sexier so people aren't like Yeah,
- 31:32Speaker 1: there's a lot of people because that should Yeah, because
- 31:36Speaker 1: then like even people that are super into like green
- 31:39Speaker 1: technologies will probably be like, I want to learn about
- 31:41Speaker 1: this weird science thing. Yeah, how about plasma waste treatment?
- 31:46Speaker 1: Please listen, Signed Josh and Chuck. Yeah, I like it.
- 31:50Speaker 1: It's a little clumsy, will work on it. If you
- 31:53Speaker 1: want to know more about plasma treatment facilities or any
- 31:56Speaker 1: of that stuff, you can take those words in the
- 31:58Speaker 1: search bar at how of words dot com. And since
- 32:01Speaker 1: Chuck said sexy, it's time for listener mail. I'm gonna
- 32:07Speaker 1: call this you guys got Africa right. Thank you, Hey guys,
- 32:11Speaker 1: listen to your podcast about female puberty and was very
- 32:13Speaker 1: impressed with the thoughtfulness and sensitivity in which you explain
- 32:16Speaker 1: things and gave advice. Um, by the way, we heard
- 32:20Speaker 1: from a lot of people on that, and thank you.
- 32:23Speaker 1: A lot of young women, a lot of grown women,
- 32:25Speaker 1: a lot of men, and Dad's uh, and that one
- 32:28Speaker 1: meant a lot. It was really good to get that
- 32:30Speaker 1: one right, I think. Um. The one thing that we
- 32:32Speaker 1: didn't quite get right that someone has pointed out more
- 32:35Speaker 1: than a few times is uh, we said boy crazy
- 32:39Speaker 1: a lot and we should have gone out of our
- 32:40Speaker 1: way to say, like, you know, you might also be
- 32:43Speaker 1: girl crazy or you might not have sexual feelings and thoughts.
- 32:47Speaker 1: I wish we had that one back. I know. That's
- 32:50Speaker 1: you know, I'm giving us a break on that because
- 32:52Speaker 1: we people know how we feel about that stuff. We
- 32:55Speaker 1: just didn't pointed out as strongly as we should have.
- 32:58Speaker 1: But that's I mean, that's how things change and improved
- 33:00Speaker 1: those you know what we're saying that now, young young
- 33:03Speaker 1: ladies out there going through puberty, you might like other girls,
- 33:07Speaker 1: you might not like boys or girls. Uh And all
- 33:10Speaker 1: that's okay too, Yes, all right, thanks for saying that.
- 33:14Speaker 1: So back to this, probably listen to about two hundred
- 33:16Speaker 1: or more of your podcasts, man, you get a long
- 33:18Speaker 1: way to go, buddy. Uh. And I'm always like, I'm
- 33:20Speaker 1: almost the three oh one, only five after that. I'm
- 33:25Speaker 1: always happy to hear you. Guys, do your best to
- 33:26Speaker 1: be specific when you make references to events in countries
- 33:30Speaker 1: or geographic regions. What I mean by this is you
- 33:33Speaker 1: don't generalize like a lot of people do and say crap,
- 33:36Speaker 1: like in Africa they blah blah blah, or in Europe
- 33:39Speaker 1: it's normal to blah blah blah when you got to
- 33:42Speaker 1: the part of your latest show where you talk about
- 33:43Speaker 1: female puberty rights. Was elated to hear you being careful
- 33:46Speaker 1: enough to say, in Ghana, there is a village where
- 33:49Speaker 1: dot dot dot. The reason for my reaction is that
- 33:52Speaker 1: I've lived in the US for twenty years, but I'm
- 33:54Speaker 1: from Ghana. There at least twenty distinct ethnic groups and
- 33:57Speaker 1: languages in Ghana alone, and I know for a fact
- 34:00Speaker 1: that the ritual you described is not done in all
- 34:01Speaker 1: of them. In fact, I've heard of it, but I
- 34:03Speaker 1: don't think it happens anymore. By the way, the official
- 34:06Speaker 1: language in Ghana is English, so we are able to
- 34:09Speaker 1: communicate with each other. Nothing irritates US Africans more than
- 34:14Speaker 1: to hear someone started sentence within Africa. I bet it's
- 34:19Speaker 1: continent that huge, because no one says, well, in North America, no,
- 34:24Speaker 1: but they just say, like in the US, but at
- 34:26Speaker 1: least it's a confederation of like associated states. In Africa,
- 34:30Speaker 1: it's like, yeah, you're you're putting the whole continent, and
- 34:33Speaker 1: it's all these different countries with all these different cultures. Yeah,
- 34:36Speaker 1: it's amazing. So thanks guys for being so thoughtful and professional.
- 34:40Speaker 1: Eric from Seattle by way of Ghana. I guess yeah,
- 34:44Speaker 1: thanks a lot. Eric appreciate that. Thank you agreed. If
- 34:48Speaker 1: you want to get in touch with us, whether to
