WEBVTT - TechStuff Fuels Up

0:00:04.280 --> 0:00:07.240
<v Speaker 1>Get in touch with technology with tech Stuff from how

0:00:07.320 --> 0:00:14.240
<v Speaker 1>stuff works dot com. Hey there, everyone, and welcome to

0:00:14.400 --> 0:00:18.040
<v Speaker 1>tech Stuff. I'm Jonathan Strickland and i'm and Today we

0:00:18.120 --> 0:00:20.880
<v Speaker 1>are going to tackle part one of a two part

0:00:20.960 --> 0:00:26.000
<v Speaker 1>series about alternative fuels. Yes, we can technically do like

0:00:26.040 --> 0:00:28.240
<v Speaker 1>a seven part series on this, but we decided to

0:00:28.320 --> 0:00:30.600
<v Speaker 1>kind of condense it the way that you would perhaps

0:00:30.680 --> 0:00:35.360
<v Speaker 1>a natural guests or yeah, hey, looks the only one

0:00:35.360 --> 0:00:41.040
<v Speaker 1>who can. Really basically, we are compressing these subjects into

0:00:41.080 --> 0:00:43.559
<v Speaker 1>two parts. The first part is going to be kind

0:00:43.560 --> 0:00:47.040
<v Speaker 1>of an overview of the different alternatives that we think

0:00:47.080 --> 0:00:49.760
<v Speaker 1>of with alternative fuel, keeping in mind that, you know,

0:00:49.800 --> 0:00:52.400
<v Speaker 1>the ones that we're talking about today are the major players,

0:00:52.560 --> 0:00:55.560
<v Speaker 1>and that there could be an alternative fuel right around

0:00:55.560 --> 0:00:57.920
<v Speaker 1>the corner that is completely different from the ones we're

0:00:58.200 --> 0:01:02.120
<v Speaker 1>chatting about. Now, uh, you know, that's a possibility, but

0:01:02.160 --> 0:01:04.720
<v Speaker 1>these are the These are the ones that are currently

0:01:04.800 --> 0:01:08.320
<v Speaker 1>in some form of production and use in various places

0:01:08.360 --> 0:01:10.839
<v Speaker 1>around the world. It also will behoove us to mention

0:01:10.920 --> 0:01:14.319
<v Speaker 1>the fact that Lauren and I come from the United

0:01:14.400 --> 0:01:16.680
<v Speaker 1>States of America. That is where we live, that is

0:01:16.680 --> 0:01:18.880
<v Speaker 1>our frame of reference UM and a lot of the

0:01:18.920 --> 0:01:23.640
<v Speaker 1>information available to us immediately centered around that kind of experience,

0:01:23.640 --> 0:01:26.480
<v Speaker 1>so we know more about the laws, the prices, and

0:01:26.520 --> 0:01:31.240
<v Speaker 1>the general availability exactly right, right, what's the infrastructure status

0:01:31.240 --> 0:01:33.520
<v Speaker 1>in the US. Now, keep in mind that some of

0:01:33.520 --> 0:01:36.160
<v Speaker 1>these alternative fuels have a lot of support in other

0:01:36.319 --> 0:01:40.319
<v Speaker 1>nations around the world. Uh, some nations have have invested

0:01:40.319 --> 0:01:43.400
<v Speaker 1>a great deal in say propane for example, as a

0:01:43.400 --> 0:01:46.920
<v Speaker 1>possible fuel source. And we're really talking about fuel for

0:01:46.959 --> 0:01:50.919
<v Speaker 1>the most part as vehicle fuel and specifically vehicle fuel

0:01:51.200 --> 0:01:54.160
<v Speaker 1>for you guys as in consumers. Yes, we will mention

0:01:54.240 --> 0:01:56.400
<v Speaker 1>a couple of places where some of these fuels have

0:01:56.560 --> 0:02:01.120
<v Speaker 1>been used commercially or in a government fleet vehicles right,

0:02:01.240 --> 0:02:05.400
<v Speaker 1>or in industrial vehicles that are used in factories or

0:02:05.520 --> 0:02:08.320
<v Speaker 1>or construction yards or whatever. But for the most part,

0:02:08.360 --> 0:02:11.920
<v Speaker 1>we're really looking at this is the alternative to the

0:02:12.040 --> 0:02:15.960
<v Speaker 1>stuff what you put in your gas tank or diesel

0:02:16.000 --> 0:02:21.360
<v Speaker 1>tank as the case maybe, or hydrogen fuel cell or etcetera, etcetera. Yeah. So, um,

0:02:21.440 --> 0:02:24.080
<v Speaker 1>so you can look at these in lots of different ways.

0:02:24.160 --> 0:02:28.080
<v Speaker 1>You can divide them up into all sorts of different categories.

0:02:28.240 --> 0:02:32.120
<v Speaker 1>And so we kind of arbitrarily made these into our

0:02:32.160 --> 0:02:36.800
<v Speaker 1>own categories based upon my whim not not completely arbitrary.

0:02:37.160 --> 0:02:41.080
<v Speaker 1>We're first going to cover I think of biodiesel and ethanol. Yeah,

0:02:41.200 --> 0:02:43.200
<v Speaker 1>and and the idea here is that these are two

0:02:43.280 --> 0:02:48.320
<v Speaker 1>fuels that we get from uh organic sources, and then

0:02:48.360 --> 0:02:51.760
<v Speaker 1>we process it to make it into fuel. Also, these

0:02:51.800 --> 0:02:55.640
<v Speaker 1>two different fuels, they are different. Ethanol and biodesel are

0:02:55.760 --> 0:02:59.320
<v Speaker 1>not the same thing. Uh. These two fuels also, besides

0:02:59.400 --> 0:03:03.760
<v Speaker 1>requiring some processing, have some other stuff in common. For instance,

0:03:04.080 --> 0:03:07.720
<v Speaker 1>both of them you will frequently see in blended form,

0:03:07.880 --> 0:03:11.800
<v Speaker 1>meaning that we actually blend these with petroleum based fuels.

0:03:11.840 --> 0:03:14.040
<v Speaker 1>In the case of ethanol, we're talking gasoline, and with

0:03:14.080 --> 0:03:18.519
<v Speaker 1>bio diesel we're talking yeah. But anyway, in both cases,

0:03:18.680 --> 0:03:24.280
<v Speaker 1>we're talking about mixing uh this this biologically uh created

0:03:24.320 --> 0:03:28.040
<v Speaker 1>fuel with stuff that is petroleum based. Keeping in mind,

0:03:28.040 --> 0:03:30.400
<v Speaker 1>of course, if we want to go all the way back,

0:03:30.960 --> 0:03:34.800
<v Speaker 1>even petroleum based stuff was organic at one point. But sure, sure,

0:03:34.880 --> 0:03:37.280
<v Speaker 1>but but there's a difference between a between man made,

0:03:37.320 --> 0:03:41.760
<v Speaker 1>processed organics and stuff that took millions and millions and

0:03:41.840 --> 0:03:44.880
<v Speaker 1>millions of years to form the way it did. Yeah,

0:03:44.920 --> 0:03:48.160
<v Speaker 1>there's a tiny difference there. Uh So So let's let's

0:03:48.160 --> 0:03:50.840
<v Speaker 1>start with um, Well, let's start with ethanol, I think,

0:03:50.840 --> 0:03:53.280
<v Speaker 1>because that one is probably the one that that a

0:03:53.280 --> 0:03:55.360
<v Speaker 1>lot of people who may not be aware of it

0:03:55.440 --> 0:03:58.560
<v Speaker 1>are using already. Right, um, I think that in American

0:03:58.880 --> 0:04:02.960
<v Speaker 1>most places in America use a blend of gasoline to

0:04:03.000 --> 0:04:06.320
<v Speaker 1>about ethanol. Yeah, it's called E ten. That's the the

0:04:06.480 --> 0:04:10.640
<v Speaker 1>general term for that blend or gasohol. That's also what

0:04:10.720 --> 0:04:13.120
<v Speaker 1>it's often referred to, although, which sounds so goofy and

0:04:13.120 --> 0:04:17.280
<v Speaker 1>it's it's it's I've seen it increasing, or rather I

0:04:17.320 --> 0:04:19.719
<v Speaker 1>should say there's a decreasing trend to call it that.

0:04:19.800 --> 0:04:22.839
<v Speaker 1>I think it almost has a stigma against it because

0:04:22.839 --> 0:04:26.719
<v Speaker 1>people realize that uh ethanol, which by the way, is

0:04:26.839 --> 0:04:29.640
<v Speaker 1>ethyl alcohol, you know, it's it's just another name for

0:04:29.680 --> 0:04:33.640
<v Speaker 1>ethyl alcohol. Um that ethyl alcohol could be pretty hard

0:04:33.800 --> 0:04:37.359
<v Speaker 1>on some engine parts, depending upon what you know, what

0:04:37.520 --> 0:04:40.799
<v Speaker 1>your engine had in it, like various tubes and connectors

0:04:40.800 --> 0:04:43.520
<v Speaker 1>and things like that. Al Right, it is a solvent

0:04:43.680 --> 0:04:45.479
<v Speaker 1>so um So one of the problems and using some

0:04:45.520 --> 0:04:48.200
<v Speaker 1>of the higher blends and in normal engines is that

0:04:48.320 --> 0:04:52.560
<v Speaker 1>it can um a start start knocking some some extra

0:04:52.600 --> 0:04:56.240
<v Speaker 1>stuff loose um and clogging fuel filters that way, and

0:04:56.520 --> 0:04:58.799
<v Speaker 1>be can start eating away at some of the rubber

0:04:58.839 --> 0:05:02.839
<v Speaker 1>components fuel exactly exactly. And so what's what's kind of

0:05:02.839 --> 0:05:05.520
<v Speaker 1>funny is that when it's eating away at that that

0:05:05.800 --> 0:05:08.000
<v Speaker 1>stuff that's built up in an engine. Let's say that

0:05:08.040 --> 0:05:11.640
<v Speaker 1>you've been using regular gasoline in an engine for a while,

0:05:11.680 --> 0:05:15.280
<v Speaker 1>but the engine can also accept ethanol of various blends,

0:05:15.320 --> 0:05:18.920
<v Speaker 1>like even a even a high concentration of of um

0:05:18.960 --> 0:05:23.599
<v Speaker 1>ethanol to actual gasoline. Well, the nice thing is that

0:05:23.680 --> 0:05:25.960
<v Speaker 1>it's actually going to start cleaning your system. But the

0:05:26.000 --> 0:05:28.040
<v Speaker 1>problem is all that stuff that's built up has to

0:05:28.040 --> 0:05:29.960
<v Speaker 1>go somewhere, and that's when you get into that problem

0:05:29.960 --> 0:05:32.400
<v Speaker 1>of it clogging up filters and things like that. Right,

0:05:32.800 --> 0:05:35.240
<v Speaker 1>which is why should you Should you have a vehicle

0:05:35.279 --> 0:05:37.839
<v Speaker 1>that can accept both, and you start using higher blends

0:05:37.839 --> 0:05:40.960
<v Speaker 1>of ethanol um, it's recommended to replace your fuel pumps

0:05:41.000 --> 0:05:44.000
<v Speaker 1>with something that is more capable of dealing with that, right, Right,

0:05:44.040 --> 0:05:47.360
<v Speaker 1>And then once you've got everything you know cleaned out

0:05:47.480 --> 0:05:52.000
<v Speaker 1>that first run through, just have a basic maintenance and

0:05:52.040 --> 0:05:55.040
<v Speaker 1>replacement schedule, just as you would your normal vehicle. The

0:05:55.080 --> 0:05:57.920
<v Speaker 1>way most of us ignore UH and UH. I say

0:05:57.960 --> 0:06:00.440
<v Speaker 1>that because I know a lot of car owners, and

0:06:00.720 --> 0:06:03.200
<v Speaker 1>I think regular maintenance is something that just happens to

0:06:03.240 --> 0:06:07.600
<v Speaker 1>other people. Uh, I've been I've been that guy once

0:06:07.720 --> 0:06:10.560
<v Speaker 1>or twice. I I take the train, so what do

0:06:10.600 --> 0:06:14.120
<v Speaker 1>I know. But anyway, so it's it's very common in

0:06:14.160 --> 0:06:17.400
<v Speaker 1>the United States. Uh. In fact, I think something like

0:06:18.400 --> 0:06:22.800
<v Speaker 1>cent of gas stations have used some blend of ethanol.

0:06:22.880 --> 0:06:25.760
<v Speaker 1>And part of the reason for that is that ethanol

0:06:25.880 --> 0:06:29.279
<v Speaker 1>will increase the octane of your gasoline. Now, octane is

0:06:29.360 --> 0:06:32.080
<v Speaker 1>this this rating that we think of that can actually

0:06:32.120 --> 0:06:34.840
<v Speaker 1>reduce what we call engine knocking. So if you've ever

0:06:34.880 --> 0:06:38.160
<v Speaker 1>been in an old car running on you know, a

0:06:38.200 --> 0:06:41.640
<v Speaker 1>low uh octane gasoline and you start hearing this weird

0:06:41.720 --> 0:06:44.080
<v Speaker 1>knocking noise coming out of the engine, that's that's from

0:06:44.120 --> 0:06:48.120
<v Speaker 1>this this octane issue. Adding an ethanol increases the octane.

0:06:48.440 --> 0:06:52.400
<v Speaker 1>What it also does, however, is it it lowers the

0:06:52.440 --> 0:06:56.640
<v Speaker 1>actual energy content of the gasoline, because ethanol does not

0:06:56.800 --> 0:07:00.560
<v Speaker 1>have as much potential energy stored in it as gasoline, right,

0:07:00.560 --> 0:07:02.960
<v Speaker 1>which in all practicality means that the gallon for gallon,

0:07:03.040 --> 0:07:05.440
<v Speaker 1>you're going to get less mileage out of ethanol than

0:07:05.480 --> 0:07:08.360
<v Speaker 1>you will out of gasoline, right, And the less mileage

0:07:08.360 --> 0:07:11.280
<v Speaker 1>all depends upon that blend, Right, Like So if it's

0:07:11.320 --> 0:07:13.280
<v Speaker 1>an E ten blend where you've got the ten percent

0:07:13.400 --> 0:07:17.720
<v Speaker 1>ethanol and gasoline, you might get three to four percent

0:07:17.840 --> 0:07:20.000
<v Speaker 1>fewer miles per gallon than you would if you were

0:07:20.080 --> 0:07:23.880
<v Speaker 1>using just regular gasoline, if you were using eight five,

0:07:24.280 --> 0:07:26.080
<v Speaker 1>which is kind of the flip side of that, it's

0:07:26.120 --> 0:07:30.960
<v Speaker 1>ethanol and percent gasoline. This is something that flexible fuel

0:07:31.080 --> 0:07:33.240
<v Speaker 1>vehicles or f f vs as we call them in

0:07:33.280 --> 0:07:36.840
<v Speaker 1>the biz, can use. Then you're talking about a significant

0:07:36.920 --> 0:07:40.640
<v Speaker 1>drop in miles per gallon. You're talking, right, that's a

0:07:41.000 --> 0:07:44.080
<v Speaker 1>that's big, right. I mean, these are why we have

0:07:44.240 --> 0:07:48.360
<v Speaker 1>these different considerations, and we'll do a full episode about why. Uh,

0:07:48.400 --> 0:07:51.520
<v Speaker 1>there are a lot of challenges to switching to alternative fuel,

0:07:51.520 --> 0:07:53.080
<v Speaker 1>So I'm not going to really get into it there,

0:07:53.120 --> 0:07:54.840
<v Speaker 1>but you can kind of already see one of the

0:07:54.920 --> 0:07:58.040
<v Speaker 1>issues here. Um, So it does have a lower energy

0:07:58.080 --> 0:08:02.440
<v Speaker 1>content than gasoline. The cost of ethanol kind of varies

0:08:02.960 --> 0:08:05.400
<v Speaker 1>in the Midwest, where you've got a lot of places

0:08:05.400 --> 0:08:08.960
<v Speaker 1>that are actually growing the feedstocks. That's what we call

0:08:09.040 --> 0:08:12.560
<v Speaker 1>the stuff what we turn into ethanol, right, right, Starch

0:08:12.600 --> 0:08:16.480
<v Speaker 1>crops are what are used to ferment and distill um

0:08:16.520 --> 0:08:19.880
<v Speaker 1>stuff into ethanol, and especially in the US. That is

0:08:19.880 --> 0:08:22.480
<v Speaker 1>the stuff. Yes, and um so corn is here in

0:08:22.520 --> 0:08:25.040
<v Speaker 1>the US is used mostly in Brazil. I think it's sugarcane,

0:08:25.240 --> 0:08:28.120
<v Speaker 1>but you can also use wheat, barley, potatoes. Right. The

0:08:28.360 --> 0:08:31.080
<v Speaker 1>starch based or sugar based stuff can be turned into this.

0:08:31.160 --> 0:08:36.000
<v Speaker 1>You can also use cellulose based cellulosic ethanol, which would

0:08:36.000 --> 0:08:39.480
<v Speaker 1>come from things like wood chips or switch grass. Uh. Now,

0:08:39.520 --> 0:08:43.439
<v Speaker 1>this stuff has potentially a better return on investment when

0:08:43.440 --> 0:08:45.559
<v Speaker 1>it comes to energy. There's this thing called e r

0:08:45.640 --> 0:08:49.800
<v Speaker 1>o I that's energy return on investment. Whenever we're talking

0:08:49.800 --> 0:08:53.760
<v Speaker 1>about producing any sort of fuel, producing the fuel requires

0:08:53.800 --> 0:08:57.520
<v Speaker 1>you put energy into the production, and so it's really

0:08:57.559 --> 0:08:59.920
<v Speaker 1>important that the energy you get out from that pot

0:09:00.080 --> 0:09:02.160
<v Speaker 1>entol fuel, like whatever you're going to use that fuel for,

0:09:02.280 --> 0:09:04.800
<v Speaker 1>the energy is greater than what you've put in, right

0:09:04.840 --> 0:09:07.240
<v Speaker 1>because otherwise why are you doing it? Yees? Otherwise it

0:09:07.240 --> 0:09:09.480
<v Speaker 1>would be an energy sink. Because let's say, let's say

0:09:09.520 --> 0:09:11.360
<v Speaker 1>that you know, for the most part, the energy you're

0:09:11.400 --> 0:09:13.600
<v Speaker 1>going to be getting to produce the stuff is still

0:09:13.640 --> 0:09:16.640
<v Speaker 1>coming from fossil fuels, because that's what we really depend

0:09:16.679 --> 0:09:19.720
<v Speaker 1>upon right now. So if you would actually consume more

0:09:19.800 --> 0:09:22.840
<v Speaker 1>fossil fuel producing this alternative fuel than you would if

0:09:22.840 --> 0:09:24.960
<v Speaker 1>you had used the fossil fuel in the first place.

0:09:25.280 --> 0:09:27.839
<v Speaker 1>Then it's an energy sink and you're playing a losing game.

0:09:27.880 --> 0:09:30.520
<v Speaker 1>You want that energy to be greater the same the

0:09:30.559 --> 0:09:33.360
<v Speaker 1>same way that that fusion reactors are not popular yet

0:09:33.440 --> 0:09:35.959
<v Speaker 1>because they use more energy to start up than they

0:09:36.040 --> 0:09:38.920
<v Speaker 1>put out exactly. Yeah, if you've got an energy sink,

0:09:38.920 --> 0:09:41.400
<v Speaker 1>then really you've just got a thing what goes deep.

0:09:41.600 --> 0:09:43.960
<v Speaker 1>It's just what a lot in this. I apologize that

0:09:44.000 --> 0:09:45.760
<v Speaker 1>I don't know what it was that got into my head.

0:09:45.800 --> 0:09:48.840
<v Speaker 1>I shot a video today cackled insanely and then got

0:09:48.880 --> 0:09:53.200
<v Speaker 1>called on it on Twitter. Lauren, Hey, I that was

0:09:53.240 --> 0:09:55.920
<v Speaker 1>not Lauren. That was your humble narrator. That was completely different.

0:09:56.000 --> 0:09:59.079
<v Speaker 1>Fair enough, that's true. You can talk to her right so.

0:09:59.360 --> 0:10:02.400
<v Speaker 1>But some other things about ethanol, uh, they do. Ethanol

0:10:02.679 --> 0:10:05.439
<v Speaker 1>does tend to put out fewer greenhouse gas emissions than

0:10:05.480 --> 0:10:09.520
<v Speaker 1>gasoline combustion does, which is important. You know. One of

0:10:09.559 --> 0:10:11.640
<v Speaker 1>the questions we have to ask ourselves about moving to

0:10:11.640 --> 0:10:14.319
<v Speaker 1>an alternative fuel is why are you doing it right?

0:10:14.320 --> 0:10:16.120
<v Speaker 1>Because there are a lot of different potential answers you

0:10:16.120 --> 0:10:18.520
<v Speaker 1>could give, and if one of those answers is I'm

0:10:18.520 --> 0:10:23.280
<v Speaker 1>concerned about the environmental impact of gasoline consumption, then something

0:10:23.320 --> 0:10:26.200
<v Speaker 1>like this where you're talking about fewer greenhouse gas emissions,

0:10:26.440 --> 0:10:29.520
<v Speaker 1>is important. Uh, you know, so that's that's something to

0:10:29.559 --> 0:10:32.959
<v Speaker 1>keep in mind. Ethanol, of course, is also produced domestically.

0:10:33.240 --> 0:10:36.080
<v Speaker 1>That's also important because in the United States, you know,

0:10:36.200 --> 0:10:38.720
<v Speaker 1>some of our oil a great deal roil. Around half

0:10:38.720 --> 0:10:41.960
<v Speaker 1>of it really is brought in from it. Yeah, important,

0:10:42.000 --> 0:10:44.040
<v Speaker 1>and some of that's imported from places in the world

0:10:44.040 --> 0:10:46.560
<v Speaker 1>where that it would be perhaps better for us to

0:10:46.679 --> 0:10:49.839
<v Speaker 1>not be supporting economically and politically, right the money that

0:10:49.880 --> 0:10:52.880
<v Speaker 1>we are are putting out could be funding things that

0:10:52.920 --> 0:10:57.199
<v Speaker 1>could be harmful to either that region's stability or to

0:10:57.520 --> 0:11:01.000
<v Speaker 1>the United States. Is stability in general role and so

0:11:01.160 --> 0:11:05.200
<v Speaker 1>anything you can produce domestically removes that that or at

0:11:05.240 --> 0:11:10.520
<v Speaker 1>least reduces that issue. So that's another reason why ethanol

0:11:10.640 --> 0:11:13.760
<v Speaker 1>is considered to be a nice alternative, is because it's

0:11:13.800 --> 0:11:17.440
<v Speaker 1>something that we can produce domestically. However, Uh, there's also

0:11:17.520 --> 0:11:21.040
<v Speaker 1>an issue about how much ethanol we produce versus um

0:11:21.160 --> 0:11:23.640
<v Speaker 1>how much gasoline we produce. But again, I'll save that

0:11:23.679 --> 0:11:26.440
<v Speaker 1>for the next show. I don't want to spoil everything

0:11:26.440 --> 0:11:30.000
<v Speaker 1>in this one. But anyway, um, yeah, I mean that's

0:11:30.080 --> 0:11:33.840
<v Speaker 1>that's generally the big picture on ethanol now for ethanol,

0:11:34.040 --> 0:11:36.240
<v Speaker 1>for like things like that E a D five blend

0:11:36.280 --> 0:11:39.839
<v Speaker 1>where you have the ethanol. Again, that's something that's only

0:11:39.960 --> 0:11:43.640
<v Speaker 1>really useful in specific vehicles that have been tooled to

0:11:43.800 --> 0:11:47.400
<v Speaker 1>accept that as a fuel, so called that flexible fuel vehicles,

0:11:47.480 --> 0:11:50.920
<v Speaker 1>right exactly. So you don't want to fill up your

0:11:51.000 --> 0:11:54.520
<v Speaker 1>your right off the lot car that normally runs on

0:11:54.559 --> 0:11:57.080
<v Speaker 1>gasoline with E eighty five because that's not a good

0:11:57.080 --> 0:12:00.480
<v Speaker 1>fuel for it. It could eat through those rubber hoses

0:12:00.520 --> 0:12:04.160
<v Speaker 1>like you were talking about, Lauren. So this is you know,

0:12:04.200 --> 0:12:06.240
<v Speaker 1>it's it's one of those things where you're really looking

0:12:06.240 --> 0:12:10.000
<v Speaker 1>at offsetting gasoline consumption, not completely replacing it. All right,

0:12:10.040 --> 0:12:12.480
<v Speaker 1>So let's talk about biodiesel, which is the other sort

0:12:12.480 --> 0:12:17.000
<v Speaker 1>of biological fuel source that we wanted to mention. Biodiesel,

0:12:17.120 --> 0:12:19.920
<v Speaker 1>of course, as the name suggests, is not a replacement

0:12:19.920 --> 0:12:23.120
<v Speaker 1>for gasoline. It's more like a substitute for diesel, which

0:12:23.160 --> 0:12:27.040
<v Speaker 1>is again a petroleum based fuel, but it's different from gasoline.

0:12:27.360 --> 0:12:32.960
<v Speaker 1>So a gasoline engine will not burn diesel fuel efficiently.

0:12:32.960 --> 0:12:36.120
<v Speaker 1>You have to have a diesel engine to do that now.

0:12:36.240 --> 0:12:41.240
<v Speaker 1>I actually remember when diesel cars were more popular than

0:12:41.280 --> 0:12:44.960
<v Speaker 1>they are now, because that's how old I am. I

0:12:45.000 --> 0:12:46.840
<v Speaker 1>was about to say, I don't remember that at all, Jonathan,

0:12:46.840 --> 0:12:48.679
<v Speaker 1>and I'm not even making fun of you right now. Yeah, no,

0:12:48.840 --> 0:12:51.320
<v Speaker 1>I remember it because, uh I was alive in the

0:12:51.360 --> 0:12:55.920
<v Speaker 1>seventies and nine, I saw diesel engine cars. Uh, you know,

0:12:55.920 --> 0:13:01.719
<v Speaker 1>because they're still very common in industrial use large vehicles

0:13:01.760 --> 0:13:06.520
<v Speaker 1>like buses or trucks. But and there are still cars

0:13:06.559 --> 0:13:11.439
<v Speaker 1>that are diesel engine cars. They're just not as common. Yeah,

0:13:11.480 --> 0:13:12.920
<v Speaker 1>a lot of And I did want to mention a

0:13:12.920 --> 0:13:15.840
<v Speaker 1>lot of the changes that have been made to how

0:13:15.880 --> 0:13:19.199
<v Speaker 1>we consume fossil fuels started out in the nineteen seventies

0:13:19.240 --> 0:13:22.360
<v Speaker 1>with them a the here in America, the the Clean

0:13:22.400 --> 0:13:25.680
<v Speaker 1>Air Act being passed by the Environmental Protection Agency, and

0:13:25.760 --> 0:13:28.679
<v Speaker 1>also the Arab oil Embargo from seventy three to seventy four,

0:13:28.720 --> 0:13:32.000
<v Speaker 1>and then the Iranian Revolution from seventy seventy nine. Yeah,

0:13:32.000 --> 0:13:35.080
<v Speaker 1>we had some major fuel crises in the United States

0:13:35.080 --> 0:13:38.679
<v Speaker 1>and the seventies which really started the ball rolling. Things

0:13:38.720 --> 0:13:40.760
<v Speaker 1>that have kept the ball rolling are everything from the

0:13:40.800 --> 0:13:43.720
<v Speaker 1>domestic safety issue that I referred to earlier and the

0:13:43.800 --> 0:13:46.920
<v Speaker 1>environmental issue as well as just people concerned with trying

0:13:46.920 --> 0:13:49.480
<v Speaker 1>to find a way that would uh some sort of

0:13:49.480 --> 0:13:52.760
<v Speaker 1>fuel that could be less expensive, less volatile in price

0:13:52.920 --> 0:13:57.559
<v Speaker 1>than gasoline, right because between say seventy eight and one UM,

0:13:57.840 --> 0:14:01.880
<v Speaker 1>the cost of oil per barrel skyrocketed from fourteen dollars

0:14:01.880 --> 0:14:04.480
<v Speaker 1>to over thirty five. Well, I remember when I first

0:14:04.520 --> 0:14:07.560
<v Speaker 1>moved to Atlanta, gasoline was eighty five cents a gallon.

0:14:08.320 --> 0:14:11.480
<v Speaker 1>I I love watching things like a like die Hard

0:14:11.520 --> 0:14:14.360
<v Speaker 1>where suddenly it pans past a gas station and you

0:14:14.400 --> 0:14:17.120
<v Speaker 1>know that it's that it was before our time, because

0:14:17.120 --> 0:14:19.560
<v Speaker 1>it's like seventy nine cents a gallon. Yeah, now it's

0:14:19.600 --> 0:14:22.280
<v Speaker 1>over you know, three dollars a gallon easily in most

0:14:22.320 --> 0:14:24.360
<v Speaker 1>of the United States. And now that we should complain

0:14:24.400 --> 0:14:26.880
<v Speaker 1>about that because in Europe it's much much much higher,

0:14:27.000 --> 0:14:29.400
<v Speaker 1>right right, But again, but anyway, sign of the times.

0:14:29.440 --> 0:14:33.080
<v Speaker 1>So so biodiesel is interesting and that this is diesel

0:14:33.160 --> 0:14:37.000
<v Speaker 1>fuel that's manufactured from vegetable oils, animal fats, and even

0:14:37.080 --> 0:14:41.120
<v Speaker 1>recycled restaurant grease. I remember reading a news report a

0:14:41.160 --> 0:14:44.440
<v Speaker 1>few years ago, uh, an article in Creative Loafing, which

0:14:44.480 --> 0:14:49.000
<v Speaker 1>is a local weekly paper here in Atlanta, and it

0:14:49.040 --> 0:14:51.560
<v Speaker 1>was a feature on a guy out in Athens who

0:14:51.640 --> 0:14:55.040
<v Speaker 1>had had tinkered with his car so that it could

0:14:55.080 --> 0:15:00.080
<v Speaker 1>accept a form of restaurant grease with minimum amount of processing.

0:15:00.120 --> 0:15:02.880
<v Speaker 1>So he was actually using biodiesel and kind of the

0:15:03.400 --> 0:15:06.520
<v Speaker 1>issues he was running into on the official end because

0:15:06.520 --> 0:15:09.680
<v Speaker 1>this was all kind of um from a tinkerer's perspective

0:15:09.680 --> 0:15:11.960
<v Speaker 1>as opposed to this is something that was fully supported

0:15:12.000 --> 0:15:16.000
<v Speaker 1>by an infrastructure. But the idea here is that you're

0:15:16.080 --> 0:15:19.320
<v Speaker 1>using this stuff, this renewable resource, because there's you know,

0:15:19.360 --> 0:15:24.520
<v Speaker 1>we can keep growing more vegetables or animals or McDonald's,

0:15:24.640 --> 0:15:27.440
<v Speaker 1>and then we get the stuff from it, this grease

0:15:27.600 --> 0:15:30.800
<v Speaker 1>or or fat or oil and process it and in

0:15:30.840 --> 0:15:34.040
<v Speaker 1>that processing we then end up with this biodiesel. It's

0:15:34.040 --> 0:15:39.640
<v Speaker 1>a biodegradable fuel. Uh, it's non toxic, so less toxic

0:15:39.680 --> 0:15:42.200
<v Speaker 1>than say table salt, which is great, you know, right,

0:15:42.280 --> 0:15:46.520
<v Speaker 1>you know, you have a massive biodegrade or biodesel fuel spill.

0:15:46.960 --> 0:15:49.480
<v Speaker 1>It is biodegradable, it's non toxic, and it makes the

0:15:49.560 --> 0:15:53.160
<v Speaker 1>highway small like French fries. So really, I mean who

0:15:53.240 --> 0:15:55.680
<v Speaker 1>loses which which isn't to say that that a giant

0:15:55.680 --> 0:15:58.200
<v Speaker 1>oil spill of this stuff would be happy for the environment.

0:15:58.200 --> 0:16:00.880
<v Speaker 1>It's not going to like moisturize all of the seal's

0:16:00.920 --> 0:16:02.840
<v Speaker 1>faces or anything like that, but it's just you know,

0:16:02.840 --> 0:16:04.720
<v Speaker 1>but but it's a little bit less scary and easier

0:16:04.760 --> 0:16:08.280
<v Speaker 1>to clean up. Yeah, it's considered to have a lower

0:16:08.360 --> 0:16:10.960
<v Speaker 1>environmental impact from that perspective, and you still have to

0:16:10.960 --> 0:16:13.120
<v Speaker 1>have processes stuff, so you still have to put energy

0:16:13.160 --> 0:16:15.120
<v Speaker 1>into the system, just like you do with ethanol. So

0:16:15.640 --> 0:16:18.280
<v Speaker 1>don't don't think that this takes fossil fuels out entirely,

0:16:18.280 --> 0:16:21.760
<v Speaker 1>and in fact, just like ethanol, biodiesel is something that

0:16:21.840 --> 0:16:28.000
<v Speaker 1>is frequently blended with petroleum based diesel, so they're different blends. Um,

0:16:28.040 --> 0:16:31.520
<v Speaker 1>there's uh, there's B two which is only two percent

0:16:31.560 --> 0:16:36.800
<v Speaker 1>biodiesel and percent petroleum based diesel, B five which is

0:16:36.960 --> 0:16:40.160
<v Speaker 1>five percent biodiesel, and B twenty, which is biodiesel. You

0:16:40.240 --> 0:16:43.080
<v Speaker 1>can get B one hundred, although I don't think there

0:16:43.080 --> 0:16:46.160
<v Speaker 1>are any consumer vehicles that are that run on B

0:16:46.280 --> 0:16:49.200
<v Speaker 1>one hundred, but B one hundred would be one percent

0:16:49.360 --> 0:16:54.760
<v Speaker 1>pure biodiesel. Most vehicles in the United States don't go

0:16:54.960 --> 0:16:59.760
<v Speaker 1>over B five as the the recommended blend for running

0:16:59.760 --> 0:17:02.280
<v Speaker 1>into the engine. The engines that you know, the manufacturers

0:17:02.280 --> 0:17:05.600
<v Speaker 1>say this engine was not designed to run anything with

0:17:05.680 --> 0:17:09.439
<v Speaker 1>a greater than B five blend for biodiesel to diesel.

0:17:09.840 --> 0:17:12.240
<v Speaker 1>But but even even those very small concentrations can make

0:17:12.240 --> 0:17:16.080
<v Speaker 1>a very large difference in the way that the fuel burns. Right.

0:17:16.200 --> 0:17:20.680
<v Speaker 1>In fact, again just like with ethanol, the biodiesel has

0:17:20.720 --> 0:17:26.040
<v Speaker 1>a lower fuel economy than than pure diesel does. So

0:17:26.160 --> 0:17:28.600
<v Speaker 1>for example, if you go with B one hundred, it's

0:17:28.640 --> 0:17:32.520
<v Speaker 1>something like a ten percent lower fuel economy, right, which

0:17:32.520 --> 0:17:34.640
<v Speaker 1>which means that it would take about one point one

0:17:34.680 --> 0:17:37.880
<v Speaker 1>gallons of biodiesel to equal one gallon of standard right,

0:17:37.920 --> 0:17:41.119
<v Speaker 1>whereas B twenty is more like just a two percent

0:17:41.560 --> 0:17:45.160
<v Speaker 1>deficit in fuel economy. So obviously, when you're getting close

0:17:45.200 --> 0:17:48.600
<v Speaker 1>to B five or B two, the change is negligible

0:17:48.640 --> 0:17:51.159
<v Speaker 1>to the point where you probably wouldn't notice it that

0:17:51.280 --> 0:17:54.400
<v Speaker 1>much unless you're really min maxing era. You're driving experience,

0:17:54.440 --> 0:17:56.960
<v Speaker 1>and hardly anyone, I mean, there are people who do that.

0:17:57.600 --> 0:18:01.480
<v Speaker 1>There's some people who go to some pretty extreme links

0:18:01.520 --> 0:18:04.960
<v Speaker 1>to try and maximize fuel economy. My programmer friends sometimes

0:18:04.960 --> 0:18:08.560
<v Speaker 1>get bored in their hybrid vehicles and do that. Also

0:18:08.600 --> 0:18:10.520
<v Speaker 1>they're really tracking it. I think of the people who

0:18:10.560 --> 0:18:14.440
<v Speaker 1>are drafting behind massive trucks. That's not a safe thing

0:18:14.480 --> 0:18:20.200
<v Speaker 1>to do, by the way, But it does actually fuel economy,

0:18:20.600 --> 0:18:25.960
<v Speaker 1>but it decreases your life expectancy, so uh. It does

0:18:26.680 --> 0:18:31.160
<v Speaker 1>in general have fewer greenhouse gas and UH and pollutant

0:18:31.160 --> 0:18:34.119
<v Speaker 1>emissions than diesel, although there is the possibility of an

0:18:34.200 --> 0:18:38.440
<v Speaker 1>increase in nitrous oxide emissions. So it's not like this

0:18:38.560 --> 0:18:43.200
<v Speaker 1>is across the board cleaner than petroleum based diesel. But

0:18:43.720 --> 0:18:47.800
<v Speaker 1>for most of the types of emissions that we would

0:18:47.840 --> 0:18:51.600
<v Speaker 1>consider harmful, it's better than the petroleum based one. It's

0:18:51.640 --> 0:18:55.280
<v Speaker 1>just not hands down or runaway wins. So you can't

0:18:55.320 --> 0:18:57.919
<v Speaker 1>just point it bio diesel and say this is this,

0:18:57.920 --> 0:19:00.679
<v Speaker 1>this is the cure for our environmental problem, right right.

0:19:00.680 --> 0:19:04.560
<v Speaker 1>It does. It does reduce carbon dioxide emissions, but that's

0:19:04.600 --> 0:19:06.520
<v Speaker 1>a big one. I mean CEO two emissions, that's a

0:19:06.560 --> 0:19:09.119
<v Speaker 1>big problem. And also they point out that really the

0:19:09.119 --> 0:19:13.520
<v Speaker 1>CEO two emissions, the way that it quote unquote reduces them,

0:19:13.560 --> 0:19:18.200
<v Speaker 1>in part is because you are you are creating feedstocks

0:19:18.280 --> 0:19:20.639
<v Speaker 1>again in order to create the biodiesel, and by creating

0:19:20.680 --> 0:19:23.679
<v Speaker 1>the feed stocks, you're creating carbon dioxide sinks, right right,

0:19:23.680 --> 0:19:26.399
<v Speaker 1>you're offsetting some of that some of what's going to

0:19:26.400 --> 0:19:28.320
<v Speaker 1>be burned later, right, Yeah, the stuff that's going to

0:19:28.359 --> 0:19:30.640
<v Speaker 1>be released in the atmosphere is actually getting pulled in

0:19:30.760 --> 0:19:34.000
<v Speaker 1>by the stuff that is turning into growing. So in

0:19:34.320 --> 0:19:37.359
<v Speaker 1>this case, it's it's almost deceptive in a way to

0:19:37.480 --> 0:19:40.119
<v Speaker 1>say lower carbon dioxide emissions, because part of that is

0:19:40.200 --> 0:19:43.160
<v Speaker 1>due to the fact that they're saying, well, yeah, it's

0:19:43.160 --> 0:19:48.440
<v Speaker 1>lower because this stuff is taking carbon dioxide in. Yeah,

0:19:48.520 --> 0:19:50.159
<v Speaker 1>but I mean you have to That's That's one of

0:19:50.160 --> 0:19:52.320
<v Speaker 1>the other things that we'll be talking about in this

0:19:52.400 --> 0:19:55.920
<v Speaker 1>podcast is you really have to look at the big picture.

0:19:56.080 --> 0:19:59.960
<v Speaker 1>There's so many factors involved of you know, how how

0:20:00.080 --> 0:20:03.480
<v Speaker 1>you create something, how you process it, and what ship it,

0:20:03.640 --> 0:20:05.679
<v Speaker 1>how you ship it, oh yeah, yeah, and and what

0:20:05.720 --> 0:20:07.320
<v Speaker 1>it does natural gas. It's going to be big on

0:20:07.359 --> 0:20:08.960
<v Speaker 1>that one. And and and what it does to the

0:20:09.000 --> 0:20:13.800
<v Speaker 1>environment overall. Um. Another benefit of biodiesel is that it acts.

0:20:13.840 --> 0:20:16.080
<v Speaker 1>It's another thing that acts as a solvent in your engine,

0:20:16.080 --> 0:20:20.400
<v Speaker 1>which which can again create some problems initially initially if

0:20:20.440 --> 0:20:22.840
<v Speaker 1>you if you aren't um, watching out for your fuel

0:20:22.880 --> 0:20:26.760
<v Speaker 1>pump and rubber rubber bits, right, and then once uh,

0:20:26.800 --> 0:20:29.160
<v Speaker 1>once you do get all that cleaned out, all that gunk,

0:20:29.240 --> 0:20:31.760
<v Speaker 1>that's in there, then it's it should run much more

0:20:32.080 --> 0:20:36.240
<v Speaker 1>cleanly than a typical diesel engine would. And um, I

0:20:36.240 --> 0:20:37.919
<v Speaker 1>mean a lot of people point out that this is

0:20:37.960 --> 0:20:40.320
<v Speaker 1>one of those things that if we can figure out

0:20:40.320 --> 0:20:42.600
<v Speaker 1>a way to make it work, it's a huge benefit

0:20:42.680 --> 0:20:46.160
<v Speaker 1>because first of all, you're taking stuff that nobody wants

0:20:46.359 --> 0:20:49.720
<v Speaker 1>used restaurant grease, you know, stuff that would you know,

0:20:49.800 --> 0:20:51.639
<v Speaker 1>we we already have to figure out a way of

0:20:51.720 --> 0:20:54.320
<v Speaker 1>disposing of that so it doesn't clog up drains or

0:20:54.359 --> 0:20:57.400
<v Speaker 1>cause problems. If we can then take what would normally

0:20:57.440 --> 0:20:59.960
<v Speaker 1>be a waste product and turn it into a few

0:21:00.000 --> 0:21:03.760
<v Speaker 1>fuel product, then that's a win win in that scenario.

0:21:04.760 --> 0:21:06.760
<v Speaker 1>Once you start looking outside that, that's when you're like,

0:21:06.800 --> 0:21:08.080
<v Speaker 1>all right, but you have to take these other things

0:21:08.080 --> 0:21:10.919
<v Speaker 1>into consideration. Well, yeah, you know, both both biodiesel and

0:21:10.960 --> 0:21:14.159
<v Speaker 1>ethanol can be created from what we would normally be

0:21:14.200 --> 0:21:17.359
<v Speaker 1>considered as waste crops um, you know, extra bits that

0:21:17.400 --> 0:21:19.639
<v Speaker 1>we wouldn't really be using that would either you know,

0:21:19.800 --> 0:21:23.760
<v Speaker 1>go into multure, a landfill or something. Although the ethanol argument,

0:21:23.800 --> 0:21:26.520
<v Speaker 1>people get really up in arms about that because if

0:21:26.520 --> 0:21:29.040
<v Speaker 1>you're talking about growing corn just for fuel, and then

0:21:29.080 --> 0:21:33.199
<v Speaker 1>you take into account other things like starvation issues or

0:21:33.520 --> 0:21:36.359
<v Speaker 1>you know, good or effective land use. Then that brings

0:21:36.440 --> 0:21:39.320
<v Speaker 1>up another debate. But again I think that actually fits

0:21:39.320 --> 0:21:41.760
<v Speaker 1>in our second episode, probably a little more. So we'll

0:21:42.000 --> 0:21:44.520
<v Speaker 1>we'll say that, we'll we'll get on the soapbox for

0:21:44.560 --> 0:21:46.720
<v Speaker 1>the second one. Will spare you that for right now.

0:21:47.160 --> 0:21:50.680
<v Speaker 1>So that that's the biological stuff. Um, let's see, do

0:21:50.720 --> 0:21:54.399
<v Speaker 1>you want to go right into the more fossil fuel

0:21:54.440 --> 0:21:57.240
<v Speaker 1>oriented ones or do you want to do hydrogen next?

0:21:58.080 --> 0:22:00.879
<v Speaker 1>Let's let's do I've got natural gas next on my paper.

0:22:01.400 --> 0:22:04.960
<v Speaker 1>Let's do that. Then it so natural gas. We're primarily

0:22:04.960 --> 0:22:08.320
<v Speaker 1>talking about methane here. Methane is one of those greenhouse

0:22:08.320 --> 0:22:10.520
<v Speaker 1>gases that you hear about a lot. It actually has

0:22:11.040 --> 0:22:15.440
<v Speaker 1>the capacity to do far more harm than carbon dioxide,

0:22:15.480 --> 0:22:18.920
<v Speaker 1>but on a shorter time scale. So uh, it's greenhouse

0:22:18.960 --> 0:22:21.679
<v Speaker 1>effect is greater than c O two. It does not

0:22:21.960 --> 0:22:24.440
<v Speaker 1>stay in the atmosphere as long as c O two.

0:22:25.200 --> 0:22:27.120
<v Speaker 1>But um, but that's one of those things that people

0:22:27.119 --> 0:22:29.959
<v Speaker 1>will point out. But methane is a clear and odorless

0:22:30.040 --> 0:22:32.400
<v Speaker 1>gas that might surprise you when you think of all

0:22:32.400 --> 0:22:36.520
<v Speaker 1>the things that methane is said to be generated by. Um, yeah,

0:22:36.560 --> 0:22:40.160
<v Speaker 1>it on pure methane is it's clear and it's odorless.

0:22:40.200 --> 0:22:43.399
<v Speaker 1>It's only gets odors from other things that are mixed

0:22:43.400 --> 0:22:47.760
<v Speaker 1>in with it. Uh. It is normally sold in one

0:22:47.760 --> 0:22:52.800
<v Speaker 1>of two forms, either compressed natural gas where you actually

0:22:52.800 --> 0:22:56.679
<v Speaker 1>have it in compressed canisters in gas form YEP, or

0:22:56.800 --> 0:23:00.280
<v Speaker 1>liquefied natural gas, which means that it's really compressed yeah,

0:23:00.359 --> 0:23:03.400
<v Speaker 1>to the point where it's actually liquefied. Now we all

0:23:03.440 --> 0:23:06.120
<v Speaker 1>know that, or if we don't, we will soon that

0:23:06.160 --> 0:23:09.359
<v Speaker 1>when you compress gas enough, assuming that you've got the

0:23:09.480 --> 0:23:13.040
<v Speaker 1>right uh set up here, you are actually pushing those

0:23:13.160 --> 0:23:16.200
<v Speaker 1>gas atoms closer and closer together, and if you are

0:23:16.400 --> 0:23:19.360
<v Speaker 1>in the right conditions, you can then eventually get add

0:23:19.440 --> 0:23:22.560
<v Speaker 1>enough pressure where you can liquefy something. Now, once it

0:23:22.840 --> 0:23:26.359
<v Speaker 1>is released from that pressure, assuming that the temperature outside

0:23:26.359 --> 0:23:29.720
<v Speaker 1>of the pressurized compartment is greater than it's boiling point,

0:23:29.800 --> 0:23:33.399
<v Speaker 1>it will then immediately boil off into gas. Uh. We

0:23:33.480 --> 0:23:36.240
<v Speaker 1>see this with lots of different stuff. So, for example,

0:23:36.320 --> 0:23:40.360
<v Speaker 1>liquid nitrogen, if it once it's removed from being pressurized,

0:23:40.560 --> 0:23:44.640
<v Speaker 1>starts to boil off and it becomes a gaseous nitrogen,

0:23:45.080 --> 0:23:47.520
<v Speaker 1>which is why why you know you you see that

0:23:47.560 --> 0:23:50.119
<v Speaker 1>whenever you see any of those liquid nitrogen demonstrations. You

0:23:50.160 --> 0:23:55.240
<v Speaker 1>just see this this pour of Yeah, that's that's UM

0:23:55.480 --> 0:23:58.640
<v Speaker 1>part of this whole process. Well, anyway, methane is one

0:23:58.680 --> 0:24:01.960
<v Speaker 1>of those that at room temperature is a gas. It's

0:24:02.040 --> 0:24:06.159
<v Speaker 1>essentially carbon and four hydrogen atoms. That's your basic building

0:24:06.200 --> 0:24:10.920
<v Speaker 1>block for methane and UM. It can be used either

0:24:11.000 --> 0:24:15.240
<v Speaker 1>in vehicles that are dedicated to using natural gas, or

0:24:15.280 --> 0:24:18.720
<v Speaker 1>it can be used in what is called a a

0:24:18.800 --> 0:24:22.840
<v Speaker 1>duel or by fuel vehicle, which means they can use

0:24:22.920 --> 0:24:27.159
<v Speaker 1>both um methane or gasoline or diesel, depending upon what

0:24:27.200 --> 0:24:31.560
<v Speaker 1>the engine is. So. Uh, one of the reasons we

0:24:31.600 --> 0:24:34.399
<v Speaker 1>could look at natural gas as being an alternative fuel

0:24:34.640 --> 0:24:36.800
<v Speaker 1>is we produce a lot of it in the United States.

0:24:36.840 --> 0:24:40.480
<v Speaker 1>A lot of nations produce a great deal of natural gas. Yeah.

0:24:40.520 --> 0:24:43.439
<v Speaker 1>The thing about natural gases that it occurs naturally in

0:24:43.520 --> 0:24:46.959
<v Speaker 1>association with crude oil. Usually when you tap into a

0:24:47.400 --> 0:24:50.280
<v Speaker 1>into a well, you're going to get both crude oil

0:24:50.320 --> 0:24:54.359
<v Speaker 1>and natural gas. Right, So it's a byproduct in that sense. So,

0:24:54.640 --> 0:24:56.800
<v Speaker 1>but it's a byproduct that's useful. It's you know, it

0:24:57.000 --> 0:24:59.920
<v Speaker 1>means that you get two things for one process. Right.

0:25:00.000 --> 0:25:02.080
<v Speaker 1>We only started being able to use it, and I

0:25:02.160 --> 0:25:04.879
<v Speaker 1>think about the nineties, which is when they started figuring

0:25:04.920 --> 0:25:08.199
<v Speaker 1>out how to to basically bottle and transport it. Right,

0:25:08.280 --> 0:25:12.560
<v Speaker 1>it's efficiently the whole process well processing natural gas so

0:25:12.600 --> 0:25:15.080
<v Speaker 1>that you can actually draw it off of everything else

0:25:15.119 --> 0:25:19.399
<v Speaker 1>and make it into a usable fuel. Um. About natural

0:25:19.440 --> 0:25:23.720
<v Speaker 1>gas in the United States is domestically produced, so only

0:25:23.760 --> 0:25:26.920
<v Speaker 1>six percent or so is imported from outside the US.

0:25:26.920 --> 0:25:30.040
<v Speaker 1>Other nations produce all the natural gas they want, or

0:25:30.240 --> 0:25:32.080
<v Speaker 1>some of them have to import quite a bit of it.

0:25:32.440 --> 0:25:35.240
<v Speaker 1>And mostly in the US we use it for heating

0:25:35.320 --> 0:25:39.560
<v Speaker 1>and cooking. Uh, there's it's used for electric power production

0:25:39.640 --> 0:25:42.800
<v Speaker 1>and also in industrial uses. Very little of it is

0:25:42.840 --> 0:25:47.040
<v Speaker 1>being used in transportation outside of a few notable instances

0:25:47.080 --> 0:25:50.240
<v Speaker 1>like here in Atlanta, we have a public transportation system

0:25:50.280 --> 0:25:54.679
<v Speaker 1>called Marta and a lot of the buses actually just

0:25:54.800 --> 0:25:57.040
<v Speaker 1>I think just the buses, but yeah, I was about

0:25:57.080 --> 0:25:58.680
<v Speaker 1>to say trains, and I was trying to catch myself,

0:25:58.720 --> 0:26:01.040
<v Speaker 1>but yeah, the buses in mark on Marta for the

0:26:01.040 --> 0:26:03.640
<v Speaker 1>most part are natural gas buses, so they are using

0:26:03.640 --> 0:26:07.640
<v Speaker 1>this as their fuel. Uh. It tends to produce fewer

0:26:07.840 --> 0:26:14.840
<v Speaker 1>smog producing pollutants by about depending upon the vehicle's calibration

0:26:15.160 --> 0:26:18.280
<v Speaker 1>and the specific type of natural gas you're using, whether

0:26:18.320 --> 0:26:21.720
<v Speaker 1>it's that compressed natural gas or liquefied natural gas, as

0:26:21.760 --> 0:26:27.080
<v Speaker 1>well as a few other variables. It also is about um, well,

0:26:27.119 --> 0:26:30.639
<v Speaker 1>it produces five to nine percent fewer greenhouse gas emissions,

0:26:30.720 --> 0:26:35.600
<v Speaker 1>so it's cleaner than gasoline. Um although you're still producing

0:26:35.600 --> 0:26:38.879
<v Speaker 1>greenhouse gases. It's not like it's eliminating them all right, Right,

0:26:38.880 --> 0:26:41.000
<v Speaker 1>It is still a fossil fuel, so even though it's

0:26:41.000 --> 0:26:44.320
<v Speaker 1>an alternate, it's yeah, and that's another thing to remember.

0:26:44.359 --> 0:26:46.280
<v Speaker 1>It is a fossil fuel. It's not it's not a

0:26:46.280 --> 0:26:49.480
<v Speaker 1>renewable resource the way that that for example ethanol and

0:26:49.520 --> 0:26:53.160
<v Speaker 1>bio diesel. Right exactly. It does tend to be cheaper

0:26:53.280 --> 0:26:56.280
<v Speaker 1>than gasoline, so that's good. It does have lower energy

0:26:56.359 --> 0:26:58.720
<v Speaker 1>content than gasoline, so just like the other ones we've mentioned.

0:26:58.760 --> 0:27:02.040
<v Speaker 1>In fact, you're gonna see a runing theme here where

0:27:02.080 --> 0:27:04.639
<v Speaker 1>the energy content of the fuel when you when you

0:27:04.680 --> 0:27:08.399
<v Speaker 1>compare it to a comparable amount of gasoline is lower.

0:27:08.600 --> 0:27:10.960
<v Speaker 1>One of the many reasons that gasoline became popular in

0:27:11.000 --> 0:27:14.720
<v Speaker 1>the first place was that it was so so efficient. Yeah,

0:27:14.720 --> 0:27:16.480
<v Speaker 1>I had a lot of it had a high energy

0:27:16.520 --> 0:27:20.399
<v Speaker 1>density compared to other fuels, and uh, you know, it's

0:27:21.119 --> 0:27:23.600
<v Speaker 1>another thing to keep in mind is that it's really

0:27:23.640 --> 0:27:27.159
<v Speaker 1>hard to compare some of these fuels against gasoline because

0:27:27.160 --> 0:27:29.639
<v Speaker 1>they are in different formats. Right, so, right, right, how

0:27:29.840 --> 0:27:31.720
<v Speaker 1>do you how do you compare a gallon of air

0:27:31.840 --> 0:27:34.320
<v Speaker 1>versus a gallon of liquid And you have to look

0:27:34.359 --> 0:27:38.199
<v Speaker 1>at cubic feet of gas versus a gallon of liquid.

0:27:38.200 --> 0:27:42.080
<v Speaker 1>It's it becomes very difficult to make a meaningful comparison.

0:27:42.119 --> 0:27:44.520
<v Speaker 1>Same sort of thing will come true in in hydrogen,

0:27:44.560 --> 0:27:46.359
<v Speaker 1>but I'll talk about that when we get there. Right,

0:27:46.400 --> 0:27:48.359
<v Speaker 1>the real measure that we can figure out is um

0:27:48.480 --> 0:27:50.320
<v Speaker 1>and just kind of how many how many miles per

0:27:50.320 --> 0:27:52.360
<v Speaker 1>gallon you get off of it? And and even then

0:27:52.400 --> 0:27:54.520
<v Speaker 1>you start to be affected by things like the fact

0:27:54.640 --> 0:27:58.120
<v Speaker 1>that natural gas tanks can be very heavy um and

0:27:58.119 --> 0:28:01.320
<v Speaker 1>and drag down the efficiency would be a you might,

0:28:01.359 --> 0:28:03.920
<v Speaker 1>you might. I think for me, the best measurement I

0:28:03.920 --> 0:28:05.760
<v Speaker 1>would be able to say is if you had two

0:28:05.880 --> 0:28:09.720
<v Speaker 1>vehicles that were of comparable weight and design, and they

0:28:09.720 --> 0:28:12.840
<v Speaker 1>were both fully fueled with whatever fuel they had, how

0:28:12.880 --> 0:28:14.640
<v Speaker 1>far could they get before you had to call Mom

0:28:14.720 --> 0:28:18.000
<v Speaker 1>to come pick you up? And if that number is

0:28:18.000 --> 0:28:20.160
<v Speaker 1>greater with gasoline. Than then you say, all right, well,

0:28:20.200 --> 0:28:23.000
<v Speaker 1>if you're talking about a fully fueled vehicle, whatever, the

0:28:23.040 --> 0:28:25.399
<v Speaker 1>definition of that is, whatever kind of tank it is

0:28:25.480 --> 0:28:28.560
<v Speaker 1>is filled up right, and that and that tank the

0:28:28.600 --> 0:28:32.040
<v Speaker 1>two exactly our fuel cell. The two the two vehicles

0:28:32.040 --> 0:28:34.639
<v Speaker 1>are of equivalent weight and design because you have to

0:28:34.640 --> 0:28:36.640
<v Speaker 1>figure the design too. I mean, if one of them

0:28:36.680 --> 0:28:38.240
<v Speaker 1>is if they both weigh the same, but one of

0:28:38.280 --> 0:28:40.120
<v Speaker 1>them is essentially a wall and the other one is

0:28:40.120 --> 0:28:42.640
<v Speaker 1>a super sleek car, then obviously that's going to play

0:28:42.640 --> 0:28:45.320
<v Speaker 1>a part. It's one if one way is like a

0:28:45.440 --> 0:28:48.360
<v Speaker 1>best spun, the other is a STV, right right, Yeah,

0:28:48.400 --> 0:28:50.800
<v Speaker 1>these are these are This just just shows you how

0:28:50.840 --> 0:28:53.160
<v Speaker 1>complex this problem is. It really is one of those

0:28:53.160 --> 0:28:55.200
<v Speaker 1>things where if you look at it just on the

0:28:55.240 --> 0:28:58.120
<v Speaker 1>surface and you say, oh, this has fewer greenhouse gas

0:28:58.120 --> 0:29:01.600
<v Speaker 1>emissions and uh and and it's not nearly as many

0:29:01.600 --> 0:29:05.480
<v Speaker 1>particulars that we should use this all the time, and

0:29:05.560 --> 0:29:08.520
<v Speaker 1>then you look at all the factors. Yeah, it's a

0:29:08.560 --> 0:29:10.600
<v Speaker 1>complicated problem. I'm glad that this I'm glad I just

0:29:10.640 --> 0:29:12.520
<v Speaker 1>get to pay to talk about it as opposed to

0:29:12.520 --> 0:29:16.400
<v Speaker 1>have to make the decisions. All right. Before the break,

0:29:16.400 --> 0:29:19.360
<v Speaker 1>we talked about natural gas. Let's talk about another type

0:29:19.440 --> 0:29:24.760
<v Speaker 1>of fossil fuel, propane, which is also called liquefied petroleum

0:29:24.840 --> 0:29:27.880
<v Speaker 1>gas UM. You know, we talked about how natural gas

0:29:27.920 --> 0:29:30.240
<v Speaker 1>we we can find that in the same places that

0:29:30.280 --> 0:29:33.959
<v Speaker 1>we find oil. Propane is actually something that is truly

0:29:34.040 --> 0:29:38.320
<v Speaker 1>a byproduct of natural gas, processing of yeah, or or

0:29:38.360 --> 0:29:41.520
<v Speaker 1>even of crude oil. So we can get it from

0:29:42.040 --> 0:29:45.920
<v Speaker 1>processing natural gas or crude oil. Propane is h is

0:29:46.120 --> 0:29:51.040
<v Speaker 1>this colorless and odorless fuel very much, you know, just

0:29:51.080 --> 0:29:52.959
<v Speaker 1>as methane is colorless and odorless. By the way, if

0:29:52.960 --> 0:29:55.160
<v Speaker 1>you if you're wondering how is this possible? Because I

0:29:55.240 --> 0:29:59.000
<v Speaker 1>know the smell of things like natural gas, that's because uh,

0:29:59.360 --> 0:30:02.520
<v Speaker 1>odorance are actually mixed in with that that fuel. So

0:30:02.720 --> 0:30:06.040
<v Speaker 1>they're so dangerous that if if they weren't, then if

0:30:06.080 --> 0:30:08.880
<v Speaker 1>you got a leak, it's a lot easier to send

0:30:09.040 --> 0:30:13.840
<v Speaker 1>detect a leak than to die of overexposure. You would

0:30:13.840 --> 0:30:16.160
<v Speaker 1>want there to be some way of detecting it apart

0:30:16.240 --> 0:30:19.640
<v Speaker 1>from a spark ends up igniting a huge explosion obviously,

0:30:19.760 --> 0:30:23.440
<v Speaker 1>so by mixing odorance, and it's really just to alert

0:30:23.600 --> 0:30:27.480
<v Speaker 1>safety measure to its presence. Um. Right, So propane and

0:30:27.520 --> 0:30:30.440
<v Speaker 1>butane um, which you know, is used in in lighter

0:30:30.440 --> 0:30:34.400
<v Speaker 1>fluid are both collected during the production of natural gas

0:30:34.480 --> 0:30:38.240
<v Speaker 1>and oil refinery in order to prevent them from condensing

0:30:38.280 --> 0:30:41.800
<v Speaker 1>and causing processing difficulties. Right, so we can actually use

0:30:41.840 --> 0:30:45.320
<v Speaker 1>this in other formats as well, other other uses. So

0:30:45.600 --> 0:30:48.920
<v Speaker 1>in the United States, for example, propanes used in home

0:30:49.000 --> 0:30:52.640
<v Speaker 1>and water heating. It's used in cooking as a strickland,

0:30:52.840 --> 0:30:56.480
<v Speaker 1>I am very well aware of propane and propane accessories.

0:30:57.200 --> 0:31:00.960
<v Speaker 1>That joke was never funny. And then it's also used

0:31:00.960 --> 0:31:04.720
<v Speaker 1>in refrigerating and clothes drying and farm in industrial equipment,

0:31:04.800 --> 0:31:08.200
<v Speaker 1>and even in drying corn. That's mainly what we use

0:31:08.240 --> 0:31:11.600
<v Speaker 1>it for here in the United States. The propane here

0:31:11.600 --> 0:31:14.680
<v Speaker 1>in the US comes from domestic sources, so again we've

0:31:14.880 --> 0:31:17.920
<v Speaker 1>mostly we've produce it ourselves here in the US, and

0:31:17.960 --> 0:31:22.240
<v Speaker 1>we don't import that much compared to the stuff we produce. UH.

0:31:22.400 --> 0:31:26.120
<v Speaker 1>As a fuel, it does have lower carbon dioxide emissions

0:31:26.160 --> 0:31:30.440
<v Speaker 1>than gasoline, but it also has a lower energy content. Yes,

0:31:30.560 --> 0:31:32.920
<v Speaker 1>so again if you're if you're talking about a fully

0:31:32.960 --> 0:31:36.200
<v Speaker 1>fueled vehicle with propane versus a fully fueled vehicle with gasoline,

0:31:36.600 --> 0:31:38.880
<v Speaker 1>you may not be able to go as far in

0:31:38.920 --> 0:31:43.440
<v Speaker 1>the propane vehicle. Uh. It also can emit fewer carbon

0:31:43.480 --> 0:31:48.120
<v Speaker 1>monoxide and non methane hydrocarbon emissions, so it's also cleaner

0:31:48.120 --> 0:31:51.520
<v Speaker 1>in that respect. It tends to be less expensive than gasoline,

0:31:51.520 --> 0:31:54.760
<v Speaker 1>although that price can fluctuate over time, right, right, even

0:31:54.760 --> 0:31:56.720
<v Speaker 1>even for the course of a year, especially here in

0:31:56.760 --> 0:31:58.440
<v Speaker 1>the U S where we use it a lot for heating,

0:31:58.480 --> 0:32:00.920
<v Speaker 1>it can be very much mar pensive than gasoline in

0:32:00.920 --> 0:32:03.560
<v Speaker 1>the winter, and then very much cheaper in the summer. Yep.

0:32:03.760 --> 0:32:06.320
<v Speaker 1>All depends on on when and where you're you're picking

0:32:06.320 --> 0:32:09.440
<v Speaker 1>it up. Uh. And it's um, you know, it's it's

0:32:09.440 --> 0:32:12.840
<v Speaker 1>got a higher octane than gasoline does, but like you said,

0:32:12.920 --> 0:32:15.040
<v Speaker 1>has a lower fuel economy, so it does have a

0:32:15.080 --> 0:32:17.840
<v Speaker 1>trade off. And it's a fossil fuel, you know, just

0:32:17.880 --> 0:32:20.640
<v Speaker 1>like natural gas is a fossil fuel. So it is

0:32:20.680 --> 0:32:23.880
<v Speaker 1>technically non renewable, right, So renewable over the course of

0:32:23.960 --> 0:32:27.360
<v Speaker 1>billions of years, right right, It's it's not renewable on

0:32:27.400 --> 0:32:29.720
<v Speaker 1>any kind of time frame that does us any good

0:32:29.800 --> 0:32:32.440
<v Speaker 1>whatsoever until we hit that fancy singularity thing that's coming

0:32:32.480 --> 0:32:35.040
<v Speaker 1>in twenty to forty years, right. And and like like

0:32:35.160 --> 0:32:38.560
<v Speaker 1>the compressed natural gas, you have to worry about how

0:32:38.560 --> 0:32:42.400
<v Speaker 1>you're going to actually store this stuff. You know, it's

0:32:42.440 --> 0:32:45.200
<v Speaker 1>not the same as the liquid gasoline that we can

0:32:45.240 --> 0:32:48.719
<v Speaker 1>pump into a car, right right, It has to be

0:32:48.760 --> 0:32:52.719
<v Speaker 1>pressurized and compressed essentially. So yeah, it's it's you know,

0:32:52.760 --> 0:32:55.280
<v Speaker 1>it's it's usually under when you get a propane it's

0:32:55.320 --> 0:32:58.480
<v Speaker 1>usually a propane tank that's under a big, heavy tanks. Yeah. Yeah,

0:32:58.520 --> 0:33:01.280
<v Speaker 1>So so refueling be an issue, just as it would

0:33:01.280 --> 0:33:03.080
<v Speaker 1>be with some of the other alternatives we talked about.

0:33:03.240 --> 0:33:07.640
<v Speaker 1>Ethanol and biodiesel are again the most like gasoline, so

0:33:07.720 --> 0:33:11.240
<v Speaker 1>that you're the most compatible with current engine designs and

0:33:11.640 --> 0:33:16.040
<v Speaker 1>infrastructure infrastructure, right yeah. So so in this case, if

0:33:16.080 --> 0:33:18.840
<v Speaker 1>we were to make a switch to propane, then it

0:33:18.840 --> 0:33:23.200
<v Speaker 1>would require us to rethink how we package and deliver

0:33:23.440 --> 0:33:26.040
<v Speaker 1>and and consume this stuff, and how how would you

0:33:26.080 --> 0:33:28.200
<v Speaker 1>refuel your vehicle? Would it require you to get the

0:33:28.200 --> 0:33:31.680
<v Speaker 1>assistance of a couple of burly dudes? Probably would for me,

0:33:32.080 --> 0:33:35.800
<v Speaker 1>I don't have a large lifting capacity, so uh. But

0:33:35.880 --> 0:33:38.720
<v Speaker 1>that that's kind of the low down on propane. And

0:33:38.720 --> 0:33:40.720
<v Speaker 1>now we're going to talk a little bit about one

0:33:40.720 --> 0:33:43.520
<v Speaker 1>of my favorite elements of all time, which is good

0:33:43.560 --> 0:33:45.640
<v Speaker 1>because it's also one of the It is the most

0:33:45.640 --> 0:33:50.080
<v Speaker 1>abundant in the universe. Hydrogen. Hydrogen, yes, hydrogen, of course

0:33:50.400 --> 0:33:52.880
<v Speaker 1>is the fuel that we think about when we think

0:33:52.920 --> 0:33:55.680
<v Speaker 1>about what the sun is doing, where it's taking hydrogen

0:33:55.720 --> 0:34:00.920
<v Speaker 1>and fusing it into helium millions of degrees doom. Yeah,

0:34:01.240 --> 0:34:03.360
<v Speaker 1>I can't, I can't not do that. We've done that

0:34:03.400 --> 0:34:05.240
<v Speaker 1>before in the podcast. I know. Don't write in and

0:34:05.280 --> 0:34:07.160
<v Speaker 1>tell us that we did that joke already. We know

0:34:07.240 --> 0:34:10.800
<v Speaker 1>we did. They might they might be. Giants are awesome,

0:34:10.880 --> 0:34:13.760
<v Speaker 1>and we're not sorry. No, we're not even a little sorry.

0:34:14.040 --> 0:34:16.880
<v Speaker 1>So and we'll probably do it again in a future episode,

0:34:17.120 --> 0:34:19.080
<v Speaker 1>maybe even in the next one, who knows. But at

0:34:19.120 --> 0:34:21.400
<v Speaker 1>any rate, hydrogen can be used as a fuel in

0:34:21.440 --> 0:34:23.359
<v Speaker 1>a couple of different ways. You could just burn it

0:34:23.719 --> 0:34:28.160
<v Speaker 1>in an internal combustion engine. It is combustible. Uh, if

0:34:28.200 --> 0:34:32.200
<v Speaker 1>you were to do that, it would actually produce some

0:34:32.560 --> 0:34:35.359
<v Speaker 1>nitrous ox side as an as one of the things

0:34:35.360 --> 0:34:39.960
<v Speaker 1>that would emit a pollutant. But another way you could

0:34:40.040 --> 0:34:43.400
<v Speaker 1>use hydrogen is in a fuel cell. Hydrogen and a

0:34:43.440 --> 0:34:48.000
<v Speaker 1>fuel cells are really cool idea. It's not practical, but

0:34:48.239 --> 0:34:50.000
<v Speaker 1>at the moment, but we'll talk about that in a

0:34:50.080 --> 0:34:52.719
<v Speaker 1>little bit. First of all, the ideas that with a

0:34:52.719 --> 0:34:56.200
<v Speaker 1>fuel cell, you've got essentially a membrane and you have

0:34:56.680 --> 0:34:59.520
<v Speaker 1>hydrogen on one side of this membrane and oxygen on

0:34:59.560 --> 0:35:03.400
<v Speaker 1>the other side the membrane, and that membrane allows ions

0:35:03.440 --> 0:35:07.200
<v Speaker 1>to pass through but not electrons. So the hydrogen really

0:35:07.239 --> 0:35:09.160
<v Speaker 1>wants to get over to where the oxygen is. There's

0:35:09.160 --> 0:35:13.080
<v Speaker 1>a there's a catalyst that's on this membrane, there's an

0:35:13.080 --> 0:35:16.080
<v Speaker 1>electro light on the membrane. It's all going to facilitate

0:35:16.160 --> 0:35:18.880
<v Speaker 1>this this chemical reaction that's going to happen. Actually, this

0:35:18.960 --> 0:35:22.840
<v Speaker 1>this physical reaction really that happens. So since the hydrogen

0:35:22.880 --> 0:35:25.799
<v Speaker 1>wants to go and party with the oxygen and the

0:35:25.800 --> 0:35:28.520
<v Speaker 1>the electrons are being a total pill about it, they

0:35:28.600 --> 0:35:31.120
<v Speaker 1>ditch the electrons and then they go right on through

0:35:31.160 --> 0:35:33.719
<v Speaker 1>that that member membrane, which is kind of like the

0:35:33.719 --> 0:35:36.160
<v Speaker 1>bouncer at a club, right. You know, you want to

0:35:36.160 --> 0:35:38.520
<v Speaker 1>get in the club, but you brought your you know,

0:35:38.640 --> 0:35:41.880
<v Speaker 1>dorky friend who is totally not club material. So your

0:35:41.920 --> 0:35:44.799
<v Speaker 1>choice is either leave the club or ditch the dorky friend.

0:35:45.080 --> 0:35:48.400
<v Speaker 1>Hydrogen ditches the dorky electron friend and goes into the

0:35:48.440 --> 0:35:51.360
<v Speaker 1>club and parties with the oxygen. The electrons are thinking, oh,

0:35:51.440 --> 0:35:53.279
<v Speaker 1>I'm not having none of that. I will get into

0:35:53.320 --> 0:35:55.439
<v Speaker 1>that club. I'm just using the back door. The back

0:35:55.440 --> 0:35:57.640
<v Speaker 1>door in this case is going through some form of circuit,

0:35:58.080 --> 0:35:59.680
<v Speaker 1>and then once it goes to the circuit, it comes

0:35:59.719 --> 0:36:03.040
<v Speaker 1>to the other side of the fuel cell rejoins the

0:36:03.120 --> 0:36:05.480
<v Speaker 1>hydrogen and oxygen says, didn't get rid of me after all,

0:36:05.520 --> 0:36:07.560
<v Speaker 1>did you? And then they all have a big water

0:36:07.680 --> 0:36:11.359
<v Speaker 1>party because at that point you have H two O. Right. Yes,

0:36:11.440 --> 0:36:15.239
<v Speaker 1>this is called electrochemical conversion. I like my version where

0:36:15.239 --> 0:36:18.440
<v Speaker 1>it's a club. I like that better too. Okay, at

0:36:18.480 --> 0:36:21.640
<v Speaker 1>any rate, so the output here is really interesting. You

0:36:21.680 --> 0:36:25.680
<v Speaker 1>get electricity, you get water, and you get heat. Heat

0:36:25.760 --> 0:36:28.680
<v Speaker 1>is a byproduct as well. So a lot of people

0:36:28.680 --> 0:36:31.360
<v Speaker 1>have said fuel cells, that's gotta be the way to

0:36:31.440 --> 0:36:33.360
<v Speaker 1>the future, because think about it, you don't have to

0:36:33.360 --> 0:36:36.800
<v Speaker 1>worry about any greenhouse gas emissions except for water vapor,

0:36:36.880 --> 0:36:39.960
<v Speaker 1>which is a greenhouse gas, but it can easily be

0:36:40.080 --> 0:36:43.960
<v Speaker 1>incorporated into the water cycle, um, whereas you know other

0:36:44.000 --> 0:36:48.560
<v Speaker 1>ones can't. Uh. And the idea that it's a contained cell,

0:36:48.640 --> 0:36:51.960
<v Speaker 1>you're you're using the same product over and over again. Well, yeah, essentially,

0:36:52.000 --> 0:36:54.839
<v Speaker 1>what happens is you get the water in the fuel cell,

0:36:54.840 --> 0:36:57.040
<v Speaker 1>and then you have to refuel the fuel cell with

0:36:57.080 --> 0:36:59.880
<v Speaker 1>more hydrogen. Uh. And then the question is, all right,

0:37:00.000 --> 0:37:02.080
<v Speaker 1>where do you get the hydrogen? Uh Huh. There's the

0:37:02.160 --> 0:37:05.960
<v Speaker 1>rub because it turns out hydrogen, while plentiful, tends to

0:37:06.040 --> 0:37:09.160
<v Speaker 1>buddy up with just about everything which is which which

0:37:09.200 --> 0:37:10.799
<v Speaker 1>is a how you get the water. But but you

0:37:10.840 --> 0:37:13.880
<v Speaker 1>know you can extract hydrogen from water, but you have

0:37:13.920 --> 0:37:16.759
<v Speaker 1>to expel energy to do that. So the question then

0:37:16.880 --> 0:37:19.680
<v Speaker 1>is like, is it more efficient for you to free

0:37:19.760 --> 0:37:21.840
<v Speaker 1>up that hydrogen so that you can get that pure

0:37:22.000 --> 0:37:25.400
<v Speaker 1>hydrogen you need for the fuel cell. Is the energy

0:37:25.440 --> 0:37:28.399
<v Speaker 1>that you're pouring in to get the hydrogen more than

0:37:28.440 --> 0:37:31.120
<v Speaker 1>the benefit you're getting from the fuel cell. If it is,

0:37:31.160 --> 0:37:33.279
<v Speaker 1>then it's an energy sink, like we talked about at

0:37:33.320 --> 0:37:36.480
<v Speaker 1>the top of the podcast. And with hydrogen that tends

0:37:36.480 --> 0:37:38.280
<v Speaker 1>to be the problem is that how do you get

0:37:38.880 --> 0:37:42.520
<v Speaker 1>lots of pure hydrogen? It doesn't occur that that often

0:37:42.560 --> 0:37:45.360
<v Speaker 1>here on on Earth. Yeah, not in its unbound form.

0:37:45.480 --> 0:37:49.279
<v Speaker 1>It's almost always bound with something else. So you have

0:37:49.360 --> 0:37:51.759
<v Speaker 1>to find a way of breaking those molecular bonds to

0:37:51.800 --> 0:37:54.480
<v Speaker 1>free up that hydrogen that that requires you to put

0:37:54.520 --> 0:37:57.160
<v Speaker 1>forth a little effort, and that's that's where the that's

0:37:57.160 --> 0:37:59.239
<v Speaker 1>where the problem is, all right. I think the other

0:37:59.280 --> 0:38:02.120
<v Speaker 1>big problem with high rygen is is a perception concept

0:38:02.200 --> 0:38:05.120
<v Speaker 1>because you know, people think hydrogen and sometimes they think

0:38:05.200 --> 0:38:08.080
<v Speaker 1>Hindenburg and then they think oh the humanity and yeah,

0:38:08.120 --> 0:38:10.879
<v Speaker 1>and that's and you know it's I mean, yes, yes,

0:38:10.920 --> 0:38:14.880
<v Speaker 1>the Hindenburg was filled with hydrogen, but but really the

0:38:14.960 --> 0:38:19.759
<v Speaker 1>problem there was the aluminum powder coating and yeah, and

0:38:20.160 --> 0:38:23.879
<v Speaker 1>various other explosive properties that they weren't really thinking about

0:38:23.920 --> 0:38:26.920
<v Speaker 1>too hard. Right. It also depends on whether it's an

0:38:26.960 --> 0:38:30.200
<v Speaker 1>internal combustion engine use of hydrogen or fuel cell use

0:38:30.239 --> 0:38:33.320
<v Speaker 1>of hydrogen, but it still does have you know issues.

0:38:33.440 --> 0:38:38.040
<v Speaker 1>Procity totten really fast. How do you store it and

0:38:38.080 --> 0:38:39.720
<v Speaker 1>how do you make sure it gets to the fuel

0:38:39.719 --> 0:38:42.480
<v Speaker 1>cell safely? Or do you just replace fuel cells? Is

0:38:42.480 --> 0:38:44.920
<v Speaker 1>that the way you refuel your fuel cell vehicle? And

0:38:44.960 --> 0:38:46.680
<v Speaker 1>if so, do you need to get those burly guys

0:38:46.719 --> 0:38:49.640
<v Speaker 1>back over at the refueling station because you know, these

0:38:49.680 --> 0:38:52.000
<v Speaker 1>things get heavy. Remember, you know, when we're talking about

0:38:52.000 --> 0:38:55.600
<v Speaker 1>a fuel cell, that's one unit of what would be

0:38:55.960 --> 0:38:59.160
<v Speaker 1>essentially a huge stack of these things that yeah, because

0:38:59.160 --> 0:39:00.879
<v Speaker 1>if you just if you just plug one and it's

0:39:00.920 --> 0:39:02.440
<v Speaker 1>not going to get you very far, but you have

0:39:02.600 --> 0:39:05.600
<v Speaker 1>very much juice at all. Yeah yeah, um and and

0:39:05.600 --> 0:39:08.440
<v Speaker 1>and it would require something like like a giant steel

0:39:08.600 --> 0:39:13.360
<v Speaker 1>tank in order to create something sturdy enough to house

0:39:13.800 --> 0:39:16.560
<v Speaker 1>this kind of this kind of gas now hydrogen. And

0:39:16.600 --> 0:39:18.400
<v Speaker 1>of course, and the heavier you make the vehicle, the

0:39:18.440 --> 0:39:20.239
<v Speaker 1>more power you need to move the vehicle. So it

0:39:20.280 --> 0:39:23.480
<v Speaker 1>becomes this kind of this that you're chasing, this constant

0:39:23.520 --> 0:39:26.239
<v Speaker 1>problem that just shifts where the problem actually is. Right,

0:39:26.480 --> 0:39:28.719
<v Speaker 1>you're like, oh, I solve this, but oh now this

0:39:28.800 --> 0:39:31.840
<v Speaker 1>is the issue. Uh, this is something engineer struggle with

0:39:31.880 --> 0:39:34.920
<v Speaker 1>all the time, not just in vehicle design or alternative fuels,

0:39:34.920 --> 0:39:40.040
<v Speaker 1>but all sorts of applications. Now, hydrogen does contain less

0:39:40.160 --> 0:39:43.960
<v Speaker 1>energy than gasoline if you're talking about by volume, if

0:39:43.960 --> 0:39:47.160
<v Speaker 1>you're talking about by weight, hydrogen has the highest energy

0:39:47.239 --> 0:39:50.880
<v Speaker 1>content of any fuel. But here's the thing. Hydrogen's really, really,

0:39:50.960 --> 0:39:55.160
<v Speaker 1>really light. It's the lightest element. So when you're talking

0:39:55.160 --> 0:39:59.240
<v Speaker 1>about getting a lot of hydrogen together before it makes

0:39:59.440 --> 0:40:03.200
<v Speaker 1>a weight of any appreciable amount, that's a lot of hydrogen.

0:40:03.320 --> 0:40:05.560
<v Speaker 1>So that's why you talk about it being a low

0:40:05.760 --> 0:40:09.440
<v Speaker 1>energy by volume as opposed to a high energy by weight.

0:40:09.800 --> 0:40:11.960
<v Speaker 1>When you when you get enough for you to compare

0:40:12.000 --> 0:40:16.080
<v Speaker 1>the hydrogen versus the gasoline, it doesn't bigger than the car.

0:40:16.160 --> 0:40:20.359
<v Speaker 1>Probably it's it's that's the big issue, or one of

0:40:20.400 --> 0:40:23.160
<v Speaker 1>the many issues really in high In the United States,

0:40:23.200 --> 0:40:28.520
<v Speaker 1>hydrogen is mostly used to refine petroleum, to treat metals,

0:40:28.520 --> 0:40:32.319
<v Speaker 1>and also to produce fertilizer. So, um, that's the other

0:40:32.400 --> 0:40:34.080
<v Speaker 1>thing is that you always have to think about how

0:40:34.120 --> 0:40:38.160
<v Speaker 1>we're what we are using this stuff for currently and uh,

0:40:38.320 --> 0:40:43.319
<v Speaker 1>then thinking about the added stress we would put on them. Yeah,

0:40:43.320 --> 0:40:44.920
<v Speaker 1>and we'll talk about more than in the in the

0:40:44.920 --> 0:40:50.200
<v Speaker 1>next episode. So this leaves us with our final alternative fuel,

0:40:50.280 --> 0:40:52.680
<v Speaker 1>which is not it's not really a fuel, not in

0:40:52.680 --> 0:40:55.120
<v Speaker 1>the sense of the others, and we've already kind of

0:40:55.160 --> 0:40:58.520
<v Speaker 1>touched on it with hydrogen fuel cells, but it's electricity.

0:40:58.719 --> 0:41:01.640
<v Speaker 1>And electricity is just another are alternative to making your

0:41:01.680 --> 0:41:04.200
<v Speaker 1>cars go. And the interesting thing here is, of course,

0:41:04.239 --> 0:41:07.360
<v Speaker 1>for those of you who know your history with cars,

0:41:07.360 --> 0:41:10.120
<v Speaker 1>some of the first vehicles were electrical. Yeah, electric cars

0:41:10.160 --> 0:41:15.320
<v Speaker 1>actually pre date the gasoline powered cars. Uh, but electric

0:41:15.360 --> 0:41:20.880
<v Speaker 1>cars were while they were early versions of personal vehicles

0:41:21.239 --> 0:41:24.040
<v Speaker 1>they were a little limited. You were limited pretty much

0:41:24.080 --> 0:41:27.279
<v Speaker 1>by the area that you could drive in, and that

0:41:27.360 --> 0:41:31.680
<v Speaker 1>was mostly in cities, because they had the capacity to

0:41:31.719 --> 0:41:34.879
<v Speaker 1>generate and distribute the electricity that you would need to

0:41:34.880 --> 0:41:38.879
<v Speaker 1>to recharge your vehicle. Um once people got it into

0:41:38.880 --> 0:41:42.959
<v Speaker 1>their heads, this crazy notion of hey, this vehicle would

0:41:43.080 --> 0:41:47.160
<v Speaker 1>actually allow me to go and explore beyond just getting

0:41:47.160 --> 0:41:48.680
<v Speaker 1>from point A to point B in my city, but

0:41:50.120 --> 0:41:53.000
<v Speaker 1>out somewhere, maybe not across the wild beyond. Right, I've

0:41:53.000 --> 0:41:55.960
<v Speaker 1>always I've always wanted to drive from New York to

0:41:56.480 --> 0:41:59.799
<v Speaker 1>you know, uh to Chicago. Then you would need some

0:42:00.000 --> 0:42:03.040
<v Speaker 1>thing that would allow you to uh to get further

0:42:03.120 --> 0:42:04.759
<v Speaker 1>than that, or you would have to have some sort

0:42:04.760 --> 0:42:07.640
<v Speaker 1>of infrastructure in place that could allow you to refuel.

0:42:08.120 --> 0:42:13.040
<v Speaker 1>And that's kind of how gasoline took over. Now these

0:42:13.080 --> 0:42:15.560
<v Speaker 1>these days, of course, there are lots of hybrid vehicles

0:42:15.560 --> 0:42:19.280
<v Speaker 1>and a few all electric vehicles, and we are creating

0:42:19.360 --> 0:42:23.280
<v Speaker 1>more of an infrastructure around those for charging stations in between,

0:42:23.360 --> 0:42:24.799
<v Speaker 1>you know, so that if you don't happen to have

0:42:24.840 --> 0:42:27.799
<v Speaker 1>a house once every thirty miles along your route, right, yeah,

0:42:27.840 --> 0:42:31.040
<v Speaker 1>you can't just you know, sneakily plug in your vehicle

0:42:31.120 --> 0:42:34.840
<v Speaker 1>to whatever outlet happens to be nearby. Uh, yeah, you can.

0:42:35.000 --> 0:42:39.279
<v Speaker 1>You can support it through these official infrastructure utilities that

0:42:39.320 --> 0:42:43.279
<v Speaker 1>are out there. Also, there's uh, there are other innovations

0:42:43.280 --> 0:42:47.680
<v Speaker 1>like regenerative breaking, where you've get some which you save

0:42:47.760 --> 0:42:50.600
<v Speaker 1>up some the kinetic energy that you create from breaking

0:42:50.719 --> 0:42:53.560
<v Speaker 1>or from and normally you would just you would just

0:42:53.600 --> 0:42:55.920
<v Speaker 1>lose that energy. That energy would normally just be converted

0:42:55.920 --> 0:42:59.440
<v Speaker 1>into heat and you would lose it. But with regenerative breaking,

0:42:59.440 --> 0:43:02.239
<v Speaker 1>you're actually capturing some of that energy that otherwise would

0:43:02.280 --> 0:43:04.520
<v Speaker 1>just go into heat, and you can put that back

0:43:04.520 --> 0:43:07.480
<v Speaker 1>into the battery. Now, of course there's no way to

0:43:07.560 --> 0:43:10.360
<v Speaker 1>completely eliminate heat. If we could, we'd have the perfect

0:43:10.360 --> 0:43:12.600
<v Speaker 1>closed system and every time we use the brakes, we

0:43:12.640 --> 0:43:14.839
<v Speaker 1>would capture all of that energy and put it right

0:43:14.840 --> 0:43:17.080
<v Speaker 1>back into the battery. Doesn't mean that you would even

0:43:17.360 --> 0:43:19.320
<v Speaker 1>you would never have to recharge the battery, but it

0:43:19.360 --> 0:43:20.680
<v Speaker 1>would mean that you could do it. We could go

0:43:20.719 --> 0:43:22.600
<v Speaker 1>for a really long time. Yeah, but it turns out,

0:43:22.680 --> 0:43:24.400
<v Speaker 1>you know, we can't do that. We can't press you.

0:43:25.719 --> 0:43:31.320
<v Speaker 1>Oh your thermodynamics. Um, I blame Newton. Really, it's his fault.

0:43:32.160 --> 0:43:34.600
<v Speaker 1>If that apple had not hit his head. And he

0:43:34.640 --> 0:43:38.080
<v Speaker 1>had just stuck with figs, we would have been I

0:43:38.080 --> 0:43:41.280
<v Speaker 1>think I'm mixing things up anyway. So, uh So, getting

0:43:41.280 --> 0:43:44.919
<v Speaker 1>back into electricity, the nice thing about an electrical car

0:43:45.120 --> 0:43:49.279
<v Speaker 1>is that you really have no appreciable emissions to speak of. Right,

0:43:49.320 --> 0:43:51.520
<v Speaker 1>you know, you do have to worry about whatever the

0:43:51.560 --> 0:43:54.560
<v Speaker 1>battery is made out of, if that stuff is toxic

0:43:54.640 --> 0:43:57.040
<v Speaker 1>or dangerous, and how do you dispose of that once

0:43:57.120 --> 0:43:59.960
<v Speaker 1>you need to eventually replace it and keeping in my

0:44:00.000 --> 0:44:02.560
<v Speaker 1>and you can charge and drain a battery a lot

0:44:02.600 --> 0:44:06.319
<v Speaker 1>of several times, but eventually you will need to replace it. Um.

0:44:06.440 --> 0:44:10.839
<v Speaker 1>So there that's a concern on top of that. Just

0:44:10.880 --> 0:44:15.520
<v Speaker 1>because your car is clean, like the the electricity isn't

0:44:15.560 --> 0:44:19.680
<v Speaker 1>producing any sort of appreciable emissions, doesn't mean that there

0:44:19.719 --> 0:44:25.759
<v Speaker 1>were no emissions created during the processing of that battery, yeah,

0:44:26.000 --> 0:44:29.920
<v Speaker 1>or of the electricity that you put into that battery,

0:44:30.080 --> 0:44:32.400
<v Speaker 1>right yeah, because because how does you know, how does

0:44:32.440 --> 0:44:34.239
<v Speaker 1>power get to your house? Yeah? If you if your

0:44:34.239 --> 0:44:38.200
<v Speaker 1>power is coming from a coal powered plant, then the

0:44:38.239 --> 0:44:42.360
<v Speaker 1>fact that your car is not emitting greenhouse gases or

0:44:42.520 --> 0:44:45.920
<v Speaker 1>pollutants is nice, but it's still getting its energy from

0:44:45.960 --> 0:44:48.640
<v Speaker 1>a source that really is producing a lot of greenhouse

0:44:48.640 --> 0:44:51.600
<v Speaker 1>gases and pollutants. So in a way, the way I

0:44:51.640 --> 0:44:56.360
<v Speaker 1>like to say is that it kind of shifts the

0:44:56.520 --> 0:44:59.759
<v Speaker 1>burden the responsibility to a different party. But it's all

0:45:00.040 --> 0:45:03.480
<v Speaker 1>dull part of this overall system. So again, if your goal,

0:45:03.880 --> 0:45:06.279
<v Speaker 1>because it doesn't necessarily mean that your goal to switch

0:45:06.320 --> 0:45:09.000
<v Speaker 1>from one fuel to an alternative, it doesn't necessarily have

0:45:09.120 --> 0:45:12.520
<v Speaker 1>to be environmental. But if it is environmental, switching all

0:45:12.560 --> 0:45:14.560
<v Speaker 1>of this other stuff into consider it. You can't just

0:45:14.600 --> 0:45:18.600
<v Speaker 1>switch to electrical and think I am now saving the world.

0:45:18.680 --> 0:45:20.880
<v Speaker 1>It all depends on how the energy is produced. Now,

0:45:20.880 --> 0:45:23.600
<v Speaker 1>if your energy is being produced by plants that are

0:45:23.640 --> 0:45:27.719
<v Speaker 1>mainly using hydro power or geothermal power, or solar or

0:45:27.760 --> 0:45:31.960
<v Speaker 1>wind power. First of all, I'm amazed, uh, not so

0:45:32.040 --> 0:45:34.080
<v Speaker 1>much with the hydro power. There are quite a few

0:45:34.160 --> 0:45:37.600
<v Speaker 1>facilities that use that. But but you know, if most

0:45:37.600 --> 0:45:40.160
<v Speaker 1>people aren't off the grid enough and most people, yeah,

0:45:40.239 --> 0:45:43.120
<v Speaker 1>but most areas are not in the US anyway, are

0:45:43.160 --> 0:45:46.120
<v Speaker 1>not using that kind of power for yeah, I mean generation.

0:45:46.200 --> 0:45:48.560
<v Speaker 1>Not everyone has access to the kind of stuff. Like

0:45:48.719 --> 0:45:50.520
<v Speaker 1>you know, if you're using hydro power, you've got to

0:45:50.520 --> 0:45:53.280
<v Speaker 1>have access to a great amount of water that's in motion.

0:45:53.680 --> 0:45:55.040
<v Speaker 1>If you happen to be in a part of the

0:45:55.120 --> 0:45:57.560
<v Speaker 1>United States or the world in general that is not

0:45:58.040 --> 0:46:01.080
<v Speaker 1>close to any sort of major river or or title

0:46:01.719 --> 0:46:04.000
<v Speaker 1>motion or anything like that where you can harness this,

0:46:04.360 --> 0:46:07.359
<v Speaker 1>then you have to find something else to create your electricity.

0:46:07.560 --> 0:46:11.200
<v Speaker 1>It's not even that you're necessarily you know, uh, part

0:46:11.280 --> 0:46:13.680
<v Speaker 1>of the what what some people think of as a

0:46:13.760 --> 0:46:17.000
<v Speaker 1>giant conspiracy among car companies and oil companies and that

0:46:17.080 --> 0:46:20.040
<v Speaker 1>sort of thing. Personally, I don't believe that conspiracy really exists.

0:46:20.080 --> 0:46:22.600
<v Speaker 1>I believe that there are a lot of companies out

0:46:22.680 --> 0:46:25.120
<v Speaker 1>there that have interests and they will lobby to have

0:46:25.160 --> 0:46:28.000
<v Speaker 1>those interests protected. But I don't think it goes so

0:46:28.040 --> 0:46:32.640
<v Speaker 1>far as to let us suppress all innovation. They don't

0:46:32.640 --> 0:46:35.239
<v Speaker 1>need to, and we'll talk about more about that in

0:46:35.280 --> 0:46:39.000
<v Speaker 1>the next podcast. But but at any rate, so, yeah,

0:46:39.640 --> 0:46:42.239
<v Speaker 1>it's it's a lack of availability of um of of

0:46:42.280 --> 0:46:46.240
<v Speaker 1>a rare earth elements to to help things like photovoltaics

0:46:46.360 --> 0:46:49.000
<v Speaker 1>and and be um just just access to the natural

0:46:49.040 --> 0:46:52.200
<v Speaker 1>resources needed to to really collect wind on a wind

0:46:52.200 --> 0:46:55.360
<v Speaker 1>farm or solar energy exactly. Yeah, you may not be

0:46:55.400 --> 0:46:58.400
<v Speaker 1>in a part of the world that is conducive to

0:46:58.440 --> 0:47:01.440
<v Speaker 1>any of that, so you have to get it somehow. So, yeah,

0:47:01.520 --> 0:47:04.960
<v Speaker 1>electricity is good in theory, but again it all depends

0:47:04.960 --> 0:47:07.480
<v Speaker 1>on how that electricity was generated, whether or not you

0:47:07.520 --> 0:47:12.720
<v Speaker 1>are net doing a service to the environment. And again

0:47:12.880 --> 0:47:15.680
<v Speaker 1>if if that's not your concern, if the environment isn't

0:47:15.680 --> 0:47:17.880
<v Speaker 1>the reason you're switching to an alternative fuel, this is

0:47:18.000 --> 0:47:21.640
<v Speaker 1>a moot discussion in the first place, because, like we said,

0:47:21.640 --> 0:47:24.160
<v Speaker 1>there are lots of different reasons. All right, So that

0:47:24.280 --> 0:47:26.320
<v Speaker 1>is the overview. Do you have anything else about electricity

0:47:26.360 --> 0:47:29.880
<v Speaker 1>you wanted to add? Excellent? Alright, So we have covered

0:47:29.920 --> 0:47:33.239
<v Speaker 1>the various alternatives that are typically talked about when we

0:47:33.280 --> 0:47:36.480
<v Speaker 1>talk about alternative fuel. In our next episode, we're really

0:47:36.480 --> 0:47:39.879
<v Speaker 1>going to cover why is gasoline something that we really

0:47:39.880 --> 0:47:41.880
<v Speaker 1>depend on? We've touched on a lot of it already,

0:47:42.280 --> 0:47:45.640
<v Speaker 1>and talk about what are the big challenges to moving

0:47:45.719 --> 0:47:51.319
<v Speaker 1>to a gasoline free fuel system? And there are quite

0:47:51.360 --> 0:47:53.879
<v Speaker 1>a few challenges, as it turns out, but we'll cover

0:47:53.960 --> 0:47:56.000
<v Speaker 1>that in our next episode. If you guys have any

0:47:56.040 --> 0:47:58.799
<v Speaker 1>suggestions for future episodes that we should cover here on

0:47:58.920 --> 0:48:01.600
<v Speaker 1>Tech Stuff, please let us know. A lot of you

0:48:01.680 --> 0:48:04.440
<v Speaker 1>been writing in and giving us some great suggestions for

0:48:04.560 --> 0:48:06.600
<v Speaker 1>future topics. Thank you so much for all of your

0:48:06.640 --> 0:48:08.839
<v Speaker 1>all of your letters. Yeah, we really appreciate it. We've

0:48:08.840 --> 0:48:11.439
<v Speaker 1>been adding to the list, and trust us, that list

0:48:11.560 --> 0:48:13.440
<v Speaker 1>is very important to us because it means that we

0:48:13.480 --> 0:48:15.960
<v Speaker 1>don't have to sit there and invent stuff. We already

0:48:15.960 --> 0:48:18.279
<v Speaker 1>know what you want to hear, and when we know

0:48:18.320 --> 0:48:21.160
<v Speaker 1>what you want to hear, it makes it better for everybody.

0:48:21.200 --> 0:48:23.360
<v Speaker 1>So keep that up. Let us know, send us an email,
