1 00:00:01,160 --> 00:00:04,360 Speaker 1: Welcome to you stuff you should Know from house stuff 2 00:00:04,360 --> 00:00:12,719 Speaker 1: Works dot com. Hey you, and welcome to the podcast. 3 00:00:12,760 --> 00:00:16,360 Speaker 1: I'm Josh Clark. There's Charles to be, Chuck Bryant, Jerry 4 00:00:16,480 --> 00:00:22,560 Speaker 1: and me Josh Clark, which makes this who know the podcast? 5 00:00:22,880 --> 00:00:27,800 Speaker 1: That's right. I thought that I wrote this article, and 6 00:00:27,880 --> 00:00:31,880 Speaker 1: it turns out it didn't list not your pseudonym, Stephanie Watson. No, 7 00:00:32,080 --> 00:00:34,760 Speaker 1: I thought I updated. I did something way back in 8 00:00:34,800 --> 00:00:39,680 Speaker 1: the day on our website about geothermal energy. It might 9 00:00:39,720 --> 00:00:41,519 Speaker 1: have just been an update that I didn't end up 10 00:00:41,520 --> 00:00:45,400 Speaker 1: getting a byeline for. It was probably how to survive 11 00:00:46,200 --> 00:00:49,320 Speaker 1: shipwreck due to geo thermal energy or something like that. Right, 12 00:00:49,479 --> 00:00:52,360 Speaker 1: Maybe did you do a bunch of like survival ones. Yeah, 13 00:00:52,360 --> 00:00:54,240 Speaker 1: that was a survival guy for a while. You were 14 00:00:54,280 --> 00:00:57,440 Speaker 1: wearing that like bush hat. Uh, the Safari hat, yeah, 15 00:00:57,520 --> 00:01:00,840 Speaker 1: where one flap goes up. Huh, Like the jungle guy 16 00:01:00,880 --> 00:01:02,880 Speaker 1: from g I Joe, what was his name? I don't know. 17 00:01:03,040 --> 00:01:07,920 Speaker 1: I didn't watch those man, that's crazy crazy, I was 18 00:01:07,959 --> 00:01:14,960 Speaker 1: too sophisticated. Uh, Chuck, So do you know the Earth 19 00:01:16,080 --> 00:01:19,600 Speaker 1: is about four point eight billion years old? It's old, 20 00:01:20,120 --> 00:01:23,639 Speaker 1: super old. That's like so old. It's a lot younger 21 00:01:23,920 --> 00:01:28,360 Speaker 1: some people do. Science is pretty um much in consensus 22 00:01:28,400 --> 00:01:30,679 Speaker 1: on the idea. That's about four point eight billion years 23 00:01:30,680 --> 00:01:34,520 Speaker 1: old alright. For about the first billion of those years, 24 00:01:35,200 --> 00:01:41,000 Speaker 1: it was in a crazy state, just loco basically. So 25 00:01:41,240 --> 00:01:45,440 Speaker 1: the whole thing is supposedly formed as an accretion disk, right, 26 00:01:47,000 --> 00:01:51,400 Speaker 1: and the terrestrial planets in our Solar system, which include Earth, Mercury, Venus, 27 00:01:51,400 --> 00:01:58,240 Speaker 1: and mars um happened to attract the heavier elements elemental particles, 28 00:01:58,240 --> 00:02:01,600 Speaker 1: which created a rocky core eventually, and then more and 29 00:02:01,640 --> 00:02:08,280 Speaker 1: more stuff was um attracted to this rotating gravity pulsing core, 30 00:02:09,040 --> 00:02:11,920 Speaker 1: and the Earth was formed eventually. Right while as it 31 00:02:12,000 --> 00:02:16,840 Speaker 1: was formed or forming, at some point, another celestial body 32 00:02:17,560 --> 00:02:22,280 Speaker 1: which just took off afterward, slammed into Earth. And remember 33 00:02:22,320 --> 00:02:23,880 Speaker 1: we talked about the Moon. This is how the Moon 34 00:02:23,960 --> 00:02:27,280 Speaker 1: was formed, just basically spit out a bunch of the Earth, 35 00:02:27,800 --> 00:02:30,160 Speaker 1: and then the Moon formed its own little lucretion disk, 36 00:02:30,200 --> 00:02:33,040 Speaker 1: and then there was the Moon. Um. But when this 37 00:02:33,160 --> 00:02:36,920 Speaker 1: body hit the Earth, they think that it melted. The 38 00:02:37,040 --> 00:02:42,960 Speaker 1: impact melted the first several thousand kilometers of the Earth's surface. 39 00:02:43,760 --> 00:02:47,000 Speaker 1: The depth just melted it. It hit it that hard. 40 00:02:47,680 --> 00:02:52,000 Speaker 1: Isn't that cool? Yeah, so I really I raised this all. 41 00:02:52,240 --> 00:02:56,120 Speaker 1: I mentioned all this for two points. One that heat 42 00:02:56,720 --> 00:03:03,120 Speaker 1: that was originally part of the Earth really formation, yes, 43 00:03:03,600 --> 00:03:07,800 Speaker 1: and then secondly, the heat from the impact that eventually 44 00:03:08,120 --> 00:03:12,640 Speaker 1: calved the Moon it's still there too. Wow. Isn't that 45 00:03:12,680 --> 00:03:15,760 Speaker 1: crazy to think that after four point eight billion years 46 00:03:16,040 --> 00:03:21,680 Speaker 1: the Earth is still cooling down. Yeah, that's pretty remarkable. 47 00:03:21,720 --> 00:03:25,560 Speaker 1: That's not all. So those those account for combined about 48 00:03:25,720 --> 00:03:28,720 Speaker 1: half of the heat found in the Earth's court. The 49 00:03:28,760 --> 00:03:33,760 Speaker 1: other half is mostly from radioactive decay of isotopes in 50 00:03:33,800 --> 00:03:38,840 Speaker 1: the core. From these incredibly high temperatures and heat um, 51 00:03:38,960 --> 00:03:42,920 Speaker 1: the particles actually decay and as the decay, a particles 52 00:03:42,920 --> 00:03:47,160 Speaker 1: sloughed off, and when there's an imbalance in the mass, 53 00:03:47,200 --> 00:03:49,800 Speaker 1: that extra mass is released as heat energy. So that's 54 00:03:49,840 --> 00:03:52,400 Speaker 1: about half of the heat in the core, but it's substantial. 55 00:03:53,360 --> 00:04:00,680 Speaker 1: It is uh hundred miles, that's sixty clicks down. You're 56 00:04:00,680 --> 00:04:06,280 Speaker 1: gonna have temperatures of about seventies sid degrees fahrenheit. That's 57 00:04:06,280 --> 00:04:09,200 Speaker 1: that's hot. That's the core, baby, And at that core, 58 00:04:09,400 --> 00:04:11,760 Speaker 1: and we should say for our friends everywhere else on Earth, 59 00:04:11,800 --> 00:04:16,240 Speaker 1: that's about degrees celsius. That's right. Uh. And at that 60 00:04:16,279 --> 00:04:23,080 Speaker 1: core um. We're talking about rock melting temperatures creating magma, 61 00:04:23,120 --> 00:04:25,760 Speaker 1: which is that melted rock. So you've got the magma 62 00:04:25,760 --> 00:04:28,000 Speaker 1: down there. It's less dense, so it tends to rise. 63 00:04:28,800 --> 00:04:31,719 Speaker 1: And we talked about a lot in the volcano episode. 64 00:04:31,880 --> 00:04:35,200 Speaker 1: We talked about it some in the Geyser's episode. When 65 00:04:36,400 --> 00:04:38,599 Speaker 1: the lava flows, that is the magma. But when it 66 00:04:38,720 --> 00:04:42,400 Speaker 1: just stays down there, it heats up water underground water, 67 00:04:42,440 --> 00:04:46,520 Speaker 1: and that escapes, sometimes as geyser's uh, sometimes as hot 68 00:04:46,560 --> 00:04:49,160 Speaker 1: springs even. Yeah, it can just be like an underground 69 00:04:49,240 --> 00:04:53,320 Speaker 1: reservoir of really really really hot water, yeah, or it 70 00:04:53,400 --> 00:04:56,279 Speaker 1: just stays there. And that's what's called a geo thermal reservoir, 71 00:04:56,400 --> 00:04:59,640 Speaker 1: is when you have this really hot water heated by magma, 72 00:04:59,720 --> 00:05:03,240 Speaker 1: just hanging out down there waiting to be used. And 73 00:05:03,320 --> 00:05:07,960 Speaker 1: so just in the first fifty kilometers no, I'm sorry, 74 00:05:08,320 --> 00:05:13,400 Speaker 1: just in the first ten kilometers below the Earth's surface, right, yes, 75 00:05:13,720 --> 00:05:19,200 Speaker 1: not that deep, there is an estimated fifty thousand times 76 00:05:19,279 --> 00:05:22,400 Speaker 1: more energy in the form of heat then there is 77 00:05:22,600 --> 00:05:25,320 Speaker 1: in all of the oil and natural gas reserves in 78 00:05:25,360 --> 00:05:29,960 Speaker 1: the world. Fifty thousand times more energy. Right, because of 79 00:05:30,000 --> 00:05:33,560 Speaker 1: all this heat and everywhere you go on Earth, you're 80 00:05:33,600 --> 00:05:36,320 Speaker 1: going to find in some way, shape or form, this 81 00:05:36,480 --> 00:05:40,960 Speaker 1: heat that's in the Earth's surface, beneath the surface. Yes, 82 00:05:41,160 --> 00:05:44,200 Speaker 1: so I said, um, that's just waiting to be used. 83 00:05:44,240 --> 00:05:46,080 Speaker 1: It's not waiting to be used because it is being 84 00:05:46,200 --> 00:05:49,520 Speaker 1: used in the form of geothermal energy. And that is 85 00:05:49,680 --> 00:05:54,120 Speaker 1: not new. Uh. It goes back to the Roman times. 86 00:05:54,240 --> 00:05:57,719 Speaker 1: Ancient Romans used hot springs. Yeah, the city of Bath 87 00:05:57,760 --> 00:06:01,240 Speaker 1: in England, it's a Roman towns right built around hot 88 00:06:01,320 --> 00:06:03,960 Speaker 1: springs right here in North America ten thousand years ago. 89 00:06:04,839 --> 00:06:09,520 Speaker 1: Are American Paleo Indian friends. They used hot springs, they 90 00:06:09,560 --> 00:06:12,120 Speaker 1: bathed in them, they cooked in them. Yeah, they imagine 91 00:06:12,120 --> 00:06:15,080 Speaker 1: that at the same time, I don't know. They could 92 00:06:15,120 --> 00:06:19,480 Speaker 1: be like Cramer. Remember we prepared that radish flower as 93 00:06:19,520 --> 00:06:24,000 Speaker 1: he bathed. Yeah, nice, but stew. Yeah. They used to 94 00:06:24,080 --> 00:06:28,240 Speaker 1: lower FDR into the warm springs at warm Springs, Georgia. 95 00:06:28,400 --> 00:06:32,000 Speaker 1: That's right. Uh. And the first real geo thermal heating 96 00:06:32,040 --> 00:06:35,599 Speaker 1: system was developed in Boise, Idaho here in the United States. 97 00:06:36,520 --> 00:06:41,520 Speaker 1: But before that, it was developed in Italy and that 98 00:06:41,600 --> 00:06:44,040 Speaker 1: was actually after it. So the one I thought the 99 00:06:44,040 --> 00:06:46,320 Speaker 1: first one was in Pizza and Lord Ela. No, So 100 00:06:46,400 --> 00:06:49,320 Speaker 1: the first and we'll talk about the distinctions in a minute. 101 00:06:49,320 --> 00:06:52,240 Speaker 1: But the first the first plant was in Italy. Yeah, 102 00:06:52,320 --> 00:06:55,919 Speaker 1: so that was a geo thermal energy production plant. And Boise, Idaho, 103 00:06:56,000 --> 00:06:58,960 Speaker 1: they used what's called direct geo thermal energy, which is 104 00:06:59,000 --> 00:07:03,680 Speaker 1: basically where you just pipe this really hot water and 105 00:07:03,800 --> 00:07:06,640 Speaker 1: use it to heat greenhouses in the winter or there's 106 00:07:06,640 --> 00:07:09,479 Speaker 1: a lot of um cities that get snow on the 107 00:07:09,520 --> 00:07:14,360 Speaker 1: ground that have basically radiant heat sidewalks where the heat 108 00:07:14,400 --> 00:07:17,440 Speaker 1: from the geothermal springs nearby is pump an east sidewalks 109 00:07:17,520 --> 00:07:21,000 Speaker 1: or streets to keep the ice from forming. Yeah, Klamath Falls, Oregon, 110 00:07:21,480 --> 00:07:24,400 Speaker 1: they have such a system because they knew we have 111 00:07:24,520 --> 00:07:28,240 Speaker 1: a kg r A nearby, which is a known geothermal 112 00:07:28,280 --> 00:07:31,600 Speaker 1: resource area. They have water from about two hundred to 113 00:07:31,600 --> 00:07:35,840 Speaker 1: two twenty degrees just sitting underneath the ground, and they, 114 00:07:35,920 --> 00:07:38,000 Speaker 1: like you said, melt the sidewalks, They melt their bridges, 115 00:07:38,520 --> 00:07:41,400 Speaker 1: they melted up, melt their faces out there, and anything 116 00:07:41,440 --> 00:07:44,960 Speaker 1: they can with that junk. So, like I said, fifty 117 00:07:45,040 --> 00:07:47,440 Speaker 1: thousand times the amount of energy in the form of 118 00:07:47,480 --> 00:07:49,800 Speaker 1: heat just waiting to be used in the first ten 119 00:07:49,880 --> 00:07:53,520 Speaker 1: kilometers below the Earth's surface everywhere on Earth. Yeah, that's 120 00:07:53,560 --> 00:07:57,680 Speaker 1: pretty attractive, man, for a few reasons. One, everybody knows 121 00:07:57,680 --> 00:08:03,160 Speaker 1: that fossil fields are dirty, they're problematic, they require transportation. 122 00:08:03,600 --> 00:08:08,000 Speaker 1: And if you think about electrical production in the world, Um, 123 00:08:08,640 --> 00:08:13,200 Speaker 1: the world uses seventeen points seven million megawatts of electricity, 124 00:08:13,280 --> 00:08:15,240 Speaker 1: or it did in two thousand twelve. That's a ton 125 00:08:15,280 --> 00:08:19,200 Speaker 1: of electricity. Most of it was produced by gas, oil 126 00:08:19,640 --> 00:08:23,280 Speaker 1: or coal. And the whole point of all of those 127 00:08:23,320 --> 00:08:27,520 Speaker 1: things is you burn them and you create heat. Then 128 00:08:27,520 --> 00:08:30,160 Speaker 1: you use that heat to heat up water, use that 129 00:08:30,160 --> 00:08:33,880 Speaker 1: water to make steam, and use that steam to turn 130 00:08:33,920 --> 00:08:36,240 Speaker 1: a turbine. Yeah, we talked about this in one of 131 00:08:36,240 --> 00:08:39,960 Speaker 1: our other ones. How amazing electricity. Yeah, that just every 132 00:08:40,400 --> 00:08:42,840 Speaker 1: everything we've ever come up with still comes down to 133 00:08:43,320 --> 00:08:45,480 Speaker 1: trying to get that steam to turn that turbine. That's 134 00:08:45,480 --> 00:08:48,040 Speaker 1: exactly right. That's why that's why we use all of 135 00:08:48,040 --> 00:08:51,360 Speaker 1: these fossil fuels. Is too heat water, not even just 136 00:08:51,440 --> 00:08:57,800 Speaker 1: fossil fuels. Man. Nuclear power uses radioactive and they dip 137 00:08:57,840 --> 00:08:59,920 Speaker 1: it in water, It heats the water up, turns it 138 00:09:00,200 --> 00:09:04,440 Speaker 1: in vapor, spins a turbine. I mean, like with geo 139 00:09:04,480 --> 00:09:06,280 Speaker 1: thermal energy. One of the things that makes it so 140 00:09:06,320 --> 00:09:09,719 Speaker 1: attractive as you're cutting out a lot of processes. You're 141 00:09:09,760 --> 00:09:11,360 Speaker 1: you're not only are you cutting out the need to 142 00:09:11,400 --> 00:09:15,000 Speaker 1: burn fossil fuels, you're cutting out entire steps which, over 143 00:09:15,080 --> 00:09:18,560 Speaker 1: the course of the plant's lifetime, can reduce the cost 144 00:09:18,720 --> 00:09:22,760 Speaker 1: of this geothermal energy production. Yeah. And it is caught 145 00:09:22,760 --> 00:09:25,000 Speaker 1: on in a big way. I believe they are. I 146 00:09:25,000 --> 00:09:29,200 Speaker 1: think twenty countries now that are using geothermal energy. The 147 00:09:29,240 --> 00:09:32,320 Speaker 1: United States is leading the way there. Yeah. Surprisingly, I 148 00:09:32,320 --> 00:09:35,400 Speaker 1: didn't realize that. Yeah, but um, if you want to 149 00:09:35,960 --> 00:09:39,000 Speaker 1: really see it in action, go to Iceland into the 150 00:09:39,000 --> 00:09:42,080 Speaker 1: city of Ricky Vick, where basically the entire city is 151 00:09:42,120 --> 00:09:46,600 Speaker 1: heated with those uh geothermal wells. Yeah. And the country 152 00:09:46,600 --> 00:09:49,080 Speaker 1: of Iceland as a whole, a quarter of its energy 153 00:09:49,200 --> 00:09:52,400 Speaker 1: is produced geothermally amazing. Same with El Salvador. Do you 154 00:09:52,440 --> 00:09:55,320 Speaker 1: know that? Oh well, I thought you're gonna say I 155 00:09:55,320 --> 00:09:59,160 Speaker 1: did not. You got me there. Um. The thing is, though, 156 00:09:59,240 --> 00:10:03,480 Speaker 1: was world, why about seven thousand megawatts of geothermal energy 157 00:10:03,480 --> 00:10:07,120 Speaker 1: are produced? And don't forget we use seventeen point seven million. 158 00:10:07,280 --> 00:10:10,520 Speaker 1: It's still it is. But we'll talk about the different 159 00:10:10,600 --> 00:10:34,800 Speaker 1: kinds of geothermal energy right after this. All right, kinds 160 00:10:34,800 --> 00:10:37,280 Speaker 1: of geothermal energy I like this of you know that 161 00:10:37,360 --> 00:10:40,200 Speaker 1: earth science jazz is me man. Yeah, well, whatever I 162 00:10:40,240 --> 00:10:43,240 Speaker 1: did for this many years ago, I remember being very 163 00:10:43,240 --> 00:10:45,240 Speaker 1: turned on by it. I don't know if it was 164 00:10:45,360 --> 00:10:49,079 Speaker 1: updating or writing. I just remember thinking, man, this is cool. 165 00:10:49,200 --> 00:10:51,880 Speaker 1: And if you are a critic of geothermal energy, hold 166 00:10:51,920 --> 00:10:54,400 Speaker 1: your horses. We understand that there's problems with it. We're 167 00:10:54,400 --> 00:10:59,280 Speaker 1: just talking about geothermal energy and it's it's pros right now. Boy, 168 00:10:59,320 --> 00:11:02,680 Speaker 1: people get upset about alternative fuel sources. I've never under 169 00:11:03,120 --> 00:11:07,200 Speaker 1: gotten that. You know, there's a lot of money at Steak, 170 00:11:07,440 --> 00:11:12,160 Speaker 1: a lot of geopolitical posturing and power and stuff at steak. 171 00:11:12,960 --> 00:11:15,560 Speaker 1: The world's based on fossil fuels. I know, but I 172 00:11:15,559 --> 00:11:17,320 Speaker 1: don't know. It just doesn't make sense. It seems like 173 00:11:17,320 --> 00:11:20,079 Speaker 1: it would make more sense even for economies to like, hey, 174 00:11:20,160 --> 00:11:23,640 Speaker 1: let's pursue it all. Well that's the that's the you know, 175 00:11:23,880 --> 00:11:28,240 Speaker 1: that seems to be the prevalent mindset these days, an 176 00:11:28,320 --> 00:11:31,520 Speaker 1: energy policy that includes everything. Yeah, although I think a 177 00:11:31,520 --> 00:11:33,559 Speaker 1: lot of that though, is is just kind of paying 178 00:11:33,600 --> 00:11:36,360 Speaker 1: lip service to the alternative stuff, and it gives you, 179 00:11:36,760 --> 00:11:40,240 Speaker 1: um a blank check to pursue fossil fuels more because 180 00:11:40,280 --> 00:11:42,839 Speaker 1: you seem like you're an open minded person. Yeah, it's 181 00:11:42,880 --> 00:11:45,079 Speaker 1: just weird. I just I don't know. You hear something 182 00:11:45,120 --> 00:11:48,040 Speaker 1: about like solar power and you think I think, well 183 00:11:48,080 --> 00:11:51,679 Speaker 1: that's neat, and I'll post something about that. What does 184 00:11:51,720 --> 00:11:54,600 Speaker 1: solar power make? You think? Well, that's neat and I'll 185 00:11:54,640 --> 00:11:56,199 Speaker 1: post something about it on the stuff you should know 186 00:11:56,200 --> 00:12:00,200 Speaker 1: Facebook wall And people are just stupid. That's so, why 187 00:12:00,240 --> 00:12:02,920 Speaker 1: would anyone do that? Is up with like Facebook and 188 00:12:02,960 --> 00:12:06,320 Speaker 1: stuff like that? The worst in people. Give a man 189 00:12:06,360 --> 00:12:09,800 Speaker 1: of mask and he will show his true face wise words. 190 00:12:09,840 --> 00:12:12,000 Speaker 1: Did you just make that up? No, that's an old thing. 191 00:12:13,640 --> 00:12:17,200 Speaker 1: I think anything that says give a man uh automatically 192 00:12:17,280 --> 00:12:19,880 Speaker 1: reveals his age. You know, been around the block a 193 00:12:19,960 --> 00:12:22,120 Speaker 1: few times. Give a man of fish, he'll eat for 194 00:12:22,120 --> 00:12:25,080 Speaker 1: a day. Teach a man to fish, he'll eat for 195 00:12:25,480 --> 00:12:27,920 Speaker 1: at least two or three days if the fish are biting. 196 00:12:28,040 --> 00:12:30,480 Speaker 1: Did you make that one up? Oh, that's a good one. 197 00:12:30,559 --> 00:12:34,640 Speaker 1: Chuck the T shirt. I never catch fish, so it 198 00:12:34,640 --> 00:12:37,240 Speaker 1: should say teach a man to teach. Chuck the fish, 199 00:12:37,280 --> 00:12:39,640 Speaker 1: and he'll starve because he is a very good at catch. 200 00:12:39,720 --> 00:12:44,040 Speaker 1: Can't get a bite, Nope, he'll go to Arthur treachers instead. 201 00:12:45,280 --> 00:12:48,280 Speaker 1: Man that's still around. I think they there was one 202 00:12:48,280 --> 00:12:50,160 Speaker 1: in l A that I remember. It seems like Captain 203 00:12:50,240 --> 00:12:52,600 Speaker 1: D's really took over the market. I don't even see 204 00:12:52,640 --> 00:12:55,600 Speaker 1: Long John Silvers anymore. There's still Long John's, but I 205 00:12:55,600 --> 00:12:58,319 Speaker 1: mean like it's more Captain D's than anything, well as 206 00:12:58,320 --> 00:13:00,920 Speaker 1: it should be. Are you a Captain D's over Long 207 00:13:01,040 --> 00:13:03,920 Speaker 1: Jon's fan? Uh? I grew up on Long Done Silver's. 208 00:13:03,960 --> 00:13:07,240 Speaker 1: They got me with the free pirate hats. Yeah. Um, 209 00:13:07,280 --> 00:13:10,920 Speaker 1: I think I like the Captain D's better. I just 210 00:13:11,040 --> 00:13:14,040 Speaker 1: I just like Fried Fishy. Is Arthur Treachers like an 211 00:13:14,080 --> 00:13:16,280 Speaker 1: also ran just like those? Or is it like a 212 00:13:16,320 --> 00:13:19,000 Speaker 1: little fancier now? I think it was just another chain, 213 00:13:19,080 --> 00:13:21,800 Speaker 1: but it has seen its better days in the past. 214 00:13:22,200 --> 00:13:24,320 Speaker 1: If I'm not mistaken, I might be wrong. Someone tell 215 00:13:24,360 --> 00:13:26,679 Speaker 1: me about Arthur Treachers. Yeah, if you work at Arthur Treachers, 216 00:13:26,760 --> 00:13:30,280 Speaker 1: let us know if it's still around, all right. Direct 217 00:13:30,280 --> 00:13:34,080 Speaker 1: geo thermal energy that is, uh, that is where you 218 00:13:34,160 --> 00:13:39,120 Speaker 1: have one of those known geothermal resource areas, um, not 219 00:13:39,320 --> 00:13:42,319 Speaker 1: too far under the earth surface. That's like if you're 220 00:13:42,360 --> 00:13:44,960 Speaker 1: located near a place where there are these hot pools. Yeah, 221 00:13:44,960 --> 00:13:47,560 Speaker 1: and you're not doing anything fancy with it. You're just 222 00:13:47,600 --> 00:13:52,160 Speaker 1: basically piping that hot water into say a house and 223 00:13:52,280 --> 00:13:54,880 Speaker 1: using it as hot water at that house, which is 224 00:13:54,920 --> 00:13:58,880 Speaker 1: what that Boise District did um back in two And 225 00:13:58,920 --> 00:14:02,880 Speaker 1: you want to know something amaze, but that geo thermal 226 00:14:03,480 --> 00:14:08,079 Speaker 1: um direct use plant is still heating fo homes and 227 00:14:08,160 --> 00:14:12,160 Speaker 1: Boise today. Uh. And it is not just to give 228 00:14:12,200 --> 00:14:14,320 Speaker 1: you hot water. Um. You can also use a heat 229 00:14:14,320 --> 00:14:17,199 Speaker 1: exchanger and incorporate into your HVAC system and all of 230 00:14:17,240 --> 00:14:20,080 Speaker 1: a sudden you are using that heated water to heat 231 00:14:20,120 --> 00:14:22,480 Speaker 1: your home as well and to cool your home. Right. 232 00:14:22,560 --> 00:14:25,560 Speaker 1: So that's that's a geo thermal heat pump, I believe, right, 233 00:14:26,920 --> 00:14:29,600 Speaker 1: Uh what to heat and cool? Yeah, so I think 234 00:14:29,840 --> 00:14:32,640 Speaker 1: I think those are both. Like a geothermal heat pump 235 00:14:33,000 --> 00:14:35,920 Speaker 1: is an example of direct geo thermal energy. Direct geo 236 00:14:35,960 --> 00:14:39,720 Speaker 1: thermal energy is not necessarily just like using the hot 237 00:14:39,720 --> 00:14:41,920 Speaker 1: water to heat and cool your house. You could also 238 00:14:42,000 --> 00:14:44,440 Speaker 1: be yeah exactly, or you can just use the hot 239 00:14:44,440 --> 00:14:47,000 Speaker 1: water directly to like wash your dishes or something like that. 240 00:14:47,520 --> 00:14:50,680 Speaker 1: But with like when you're using a heat exchange or something. 241 00:14:50,920 --> 00:14:54,240 Speaker 1: This is actually extremely clever and it's it's been around 242 00:14:54,240 --> 00:14:56,960 Speaker 1: for a very long time and as the green movements 243 00:14:57,040 --> 00:15:00,600 Speaker 1: kind of caught on. Stupid movement. It's this older technology 244 00:15:00,640 --> 00:15:05,880 Speaker 1: that's starting to get re uh discovered, I guess. But basically, 245 00:15:05,880 --> 00:15:08,360 Speaker 1: if you use the geothermal heat pump, the whole idea 246 00:15:08,440 --> 00:15:12,000 Speaker 1: is that you bury in the ground beneath your house 247 00:15:12,480 --> 00:15:17,680 Speaker 1: some pipes, a closed pipe system, and there's like an 248 00:15:17,800 --> 00:15:21,400 Speaker 1: h v A C system in your house that uh 249 00:15:21,680 --> 00:15:26,480 Speaker 1: circulates air or say something like water or anti freeze 250 00:15:27,000 --> 00:15:31,320 Speaker 1: through these pipes, and it takes the heat from your 251 00:15:31,320 --> 00:15:35,840 Speaker 1: house and exchanges it through this heat exchanger in the summer, 252 00:15:36,280 --> 00:15:39,880 Speaker 1: sends it through the underground where it's cooler than it 253 00:15:39,960 --> 00:15:43,040 Speaker 1: is in your house in the summer, so that that water, 254 00:15:43,160 --> 00:15:45,600 Speaker 1: anti freeze or whatever is cooled, which brings it back 255 00:15:45,880 --> 00:15:48,160 Speaker 1: and then cools the air in your h v A 256 00:15:48,200 --> 00:15:51,080 Speaker 1: C system, which then blows out through your duct work. Yeah, 257 00:15:51,120 --> 00:15:54,080 Speaker 1: just a few feet under your feet underground, it's fifty 258 00:15:54,160 --> 00:15:56,920 Speaker 1: to sixty degrees year round. Yeah, below the frost line, 259 00:15:56,920 --> 00:16:00,360 Speaker 1: which is usually about ten ft below ground. Uh. And yeah, 260 00:16:00,640 --> 00:16:04,480 Speaker 1: if you you can, since it's a steady temperature um 261 00:16:04,480 --> 00:16:07,440 Speaker 1: depending on the season, especially if you have wild seasonal 262 00:16:07,480 --> 00:16:10,640 Speaker 1: fluctuations where it gets really cold and really hot depending 263 00:16:10,640 --> 00:16:13,800 Speaker 1: on yeah, Um, then you can really take advantage of this. 264 00:16:14,080 --> 00:16:16,600 Speaker 1: So the whole idea is if it's say like fifty 265 00:16:16,600 --> 00:16:20,040 Speaker 1: degrees in the summertime, when it's ninety degrees, if you're 266 00:16:20,400 --> 00:16:24,280 Speaker 1: cooling that liquid that's in turn cooling your air, that's easy. 267 00:16:24,680 --> 00:16:27,520 Speaker 1: But fifty degrees in the winner that seems you know, 268 00:16:28,080 --> 00:16:31,640 Speaker 1: not that much warmer, but just that little bit of 269 00:16:32,040 --> 00:16:35,600 Speaker 1: warmth that extra is, say twenty degrees on a particularly 270 00:16:35,640 --> 00:16:39,080 Speaker 1: cold day, that heats up that air, which means that 271 00:16:39,120 --> 00:16:42,600 Speaker 1: your h v a C system has less has less 272 00:16:42,720 --> 00:16:46,320 Speaker 1: energy to expend in further heating up the air to 273 00:16:46,480 --> 00:16:51,960 Speaker 1: say seventy five degrees exactly. So you're still using like 274 00:16:52,000 --> 00:16:54,720 Speaker 1: a lot of the same technology like a compressor and 275 00:16:54,760 --> 00:16:57,240 Speaker 1: all of that that you would use with a traditional 276 00:16:57,320 --> 00:17:00,200 Speaker 1: h v A C system in your home. But this 277 00:17:00,520 --> 00:17:05,359 Speaker 1: the the the steady temperature of the ground is like 278 00:17:05,400 --> 00:17:08,600 Speaker 1: you said, assisting that, so you're having you're using less 279 00:17:08,680 --> 00:17:11,359 Speaker 1: energy and and thus your energy costs are less as well. 280 00:17:11,480 --> 00:17:14,080 Speaker 1: Plus it's reliable, it's not you know that it's going 281 00:17:14,119 --> 00:17:17,280 Speaker 1: to be between fifty and sixty degrees all year round, 282 00:17:17,320 --> 00:17:20,880 Speaker 1: all year round. The third way that you can use 283 00:17:20,960 --> 00:17:23,240 Speaker 1: this is with the power plant, like we talked about, 284 00:17:23,680 --> 00:17:27,120 Speaker 1: and that is when they, like we said, they generate, 285 00:17:27,840 --> 00:17:31,400 Speaker 1: they pipe it up through the wells and they generate electricity. Uh. 286 00:17:31,440 --> 00:17:33,479 Speaker 1: There are dry steam plants where they just pipe it 287 00:17:33,520 --> 00:17:38,560 Speaker 1: directly uh into the generator empower it. That's I guess 288 00:17:38,560 --> 00:17:41,880 Speaker 1: the easiest and most cost efficient. Yeah, that's that's just yeah. 289 00:17:41,880 --> 00:17:45,640 Speaker 1: I think the one in uh Italy um and where 290 00:17:45,840 --> 00:17:50,440 Speaker 1: Lardarello I think is Lardarello, Italy in four it's still 291 00:17:50,480 --> 00:17:53,919 Speaker 1: in in online today. Basically, we have the steam, right, 292 00:17:54,000 --> 00:17:56,680 Speaker 1: and let's use it, and let's just put a turbine 293 00:17:56,680 --> 00:17:58,960 Speaker 1: on top of it, and so it cuts out all 294 00:17:59,000 --> 00:18:02,240 Speaker 1: those middlemen. It's just you're using the steam, naturally produced 295 00:18:02,240 --> 00:18:05,199 Speaker 1: steam underground to spind the turbine to produce electricity. Right. 296 00:18:05,200 --> 00:18:08,119 Speaker 1: And obviously you have to have um a great amount 297 00:18:08,119 --> 00:18:11,200 Speaker 1: of uh luck I guess to be located near such 298 00:18:11,200 --> 00:18:13,680 Speaker 1: a place. Right. And that's so that's considered a dry 299 00:18:13,760 --> 00:18:16,359 Speaker 1: steam plant. Yes. Then you have the flash steam, and 300 00:18:16,400 --> 00:18:20,320 Speaker 1: that's water between three hundred and seven hundred degrees fahrenheit 301 00:18:20,359 --> 00:18:23,240 Speaker 1: which is super hot that they draw up through a well, 302 00:18:24,000 --> 00:18:26,640 Speaker 1: uh and then use that steam to spind the turbine. 303 00:18:26,840 --> 00:18:30,480 Speaker 1: That's right. And then there's binary cycle plants. So UM, 304 00:18:30,560 --> 00:18:36,480 Speaker 1: let's say you're not located over a super hot reservoir, UM, 305 00:18:36,520 --> 00:18:38,880 Speaker 1: but you still have pretty hot water something that would 306 00:18:38,880 --> 00:18:42,160 Speaker 1: be considered like a hot springs. Typically this is between 307 00:18:42,320 --> 00:18:45,879 Speaker 1: a hundred and fifty and three hundred degree water UM, 308 00:18:46,680 --> 00:18:49,040 Speaker 1: which is as low as or as high as a 309 00:18:49,119 --> 00:18:52,560 Speaker 1: hundred and forty eight degrees celsius. Right, And what you 310 00:18:52,640 --> 00:18:55,600 Speaker 1: do is you take this water and you use it 311 00:18:55,680 --> 00:18:59,320 Speaker 1: to heat another liquid that has a lower boiling point. 312 00:19:00,040 --> 00:19:03,520 Speaker 1: Pretty clever. Then when that liquid with the lower boiling 313 00:19:03,560 --> 00:19:07,720 Speaker 1: point begins to boil, it creates the steam that powers 314 00:19:07,760 --> 00:19:10,240 Speaker 1: the turbine. So again that's like an assist I would 315 00:19:10,240 --> 00:19:13,600 Speaker 1: say probably. And then lastly, there's another one that's newer 316 00:19:13,840 --> 00:19:18,000 Speaker 1: UM that's called enhanced geo Thermal energy, and basically a 317 00:19:18,119 --> 00:19:24,439 Speaker 1: uses fracking techniques to UM create a geothermal hot spot. 318 00:19:24,840 --> 00:19:27,120 Speaker 1: So they go in and they dig wells, they dig 319 00:19:27,119 --> 00:19:30,800 Speaker 1: a deposit well, and they dig another well and exit 320 00:19:30,880 --> 00:19:34,880 Speaker 1: well right. Um. And then in between those two they 321 00:19:34,920 --> 00:19:36,680 Speaker 1: go in and just break up a bunch of this 322 00:19:36,880 --> 00:19:40,200 Speaker 1: really hot rock where there's no water necessarily but it's 323 00:19:40,240 --> 00:19:44,520 Speaker 1: super hot, right, and then they pump water into this 324 00:19:44,880 --> 00:19:48,000 Speaker 1: um hot rock bed, let it heat up, and then 325 00:19:48,040 --> 00:19:50,800 Speaker 1: they let the hot water come back up the other well, 326 00:19:51,480 --> 00:19:53,840 Speaker 1: and then they use that to create steam, usually like 327 00:19:53,880 --> 00:19:57,600 Speaker 1: a binary cycle plant. And again that spins the turbine. 328 00:19:57,720 --> 00:20:00,320 Speaker 1: It's all about spinning that turbine. All about been in 329 00:20:00,359 --> 00:20:02,440 Speaker 1: the turbine, man, all right, So let's take a break 330 00:20:02,480 --> 00:20:05,840 Speaker 1: here and we will finish up with I guess the 331 00:20:05,880 --> 00:20:08,639 Speaker 1: lowdown on how it compares to other forms of energy 332 00:20:08,680 --> 00:20:31,920 Speaker 1: out there. All right, So here we are. Is it good? 333 00:20:32,280 --> 00:20:37,280 Speaker 1: Is it bad? Well, like everything, it's both land on 334 00:20:37,320 --> 00:20:40,199 Speaker 1: the good side, though I think it's typically good. The 335 00:20:40,240 --> 00:20:45,440 Speaker 1: thing is, the bad stuff is so um rarely mentioned. 336 00:20:45,800 --> 00:20:48,040 Speaker 1: You know. Everybody thinks like geo thermal it's as green 337 00:20:48,080 --> 00:20:51,160 Speaker 1: as it gets, and there are like a really there's 338 00:20:51,200 --> 00:20:54,240 Speaker 1: a lot of about geo thermal energy that is very green. 339 00:20:54,600 --> 00:20:58,560 Speaker 1: For the most part, it emits very very little carbon 340 00:20:58,600 --> 00:21:02,879 Speaker 1: dioxide compared to a fossil fuel power plant. Yes, I 341 00:21:02,920 --> 00:21:05,919 Speaker 1: have some numbers on that. In fact, by the way, 342 00:21:05,960 --> 00:21:08,040 Speaker 1: if you've ever driven by a geo thermal plant, you 343 00:21:08,080 --> 00:21:11,439 Speaker 1: see the smoke coming out, that's not smoke, that's water vapor. 344 00:21:11,960 --> 00:21:14,960 Speaker 1: So don't get all up on your hackles water vapor 345 00:21:15,080 --> 00:21:17,199 Speaker 1: just water vapor, which and I looked this up, I 346 00:21:17,200 --> 00:21:19,960 Speaker 1: couldn't find anything. Water vapors are greenhouse gas as well, 347 00:21:19,960 --> 00:21:22,439 Speaker 1: like a pretty bad one. But I didn't see anything 348 00:21:22,440 --> 00:21:25,800 Speaker 1: where that that was like a problem with geo thermal energy. 349 00:21:25,960 --> 00:21:29,800 Speaker 1: Oh yeah, alright, So here's some numbers. They did a 350 00:21:29,800 --> 00:21:36,040 Speaker 1: case study of a coal plant. They meaning scientist scientists 351 00:21:36,040 --> 00:21:38,760 Speaker 1: science doer may or may not have been funded by 352 00:21:38,800 --> 00:21:43,399 Speaker 1: a front group. Uh, they said, Um, they studied a 353 00:21:43,400 --> 00:21:48,680 Speaker 1: coal plant with uh scrubbers with good scrubbers and emissions 354 00:21:48,720 --> 00:21:52,680 Speaker 1: control technology, so basically a newer coal plant, And they 355 00:21:52,680 --> 00:21:56,000 Speaker 1: said that admitted twenty four times more CEO two and 356 00:21:56,240 --> 00:22:00,399 Speaker 1: almost eleven thousand times more sulfur dioxide and about thirty 357 00:22:00,400 --> 00:22:04,679 Speaker 1: eight hundred times more nitrous oxide per megawatt hour than 358 00:22:04,720 --> 00:22:10,520 Speaker 1: a geothermal steam plant. Pretty good, that's not bad at all. Um. However, 359 00:22:10,600 --> 00:22:14,679 Speaker 1: one of the one of the concerns with geothermal is 360 00:22:14,840 --> 00:22:18,760 Speaker 1: it does emit sulfur dioxide, which gives it a horrible 361 00:22:18,840 --> 00:22:23,359 Speaker 1: eggy smell, yes, and contributes to acid rain. But s 362 00:22:23,440 --> 00:22:26,040 Speaker 1: O two emissions from geothermal plants for about thirty times 363 00:22:26,040 --> 00:22:29,439 Speaker 1: lower per megawott hour than coal plants, which are the 364 00:22:29,560 --> 00:22:32,679 Speaker 1: largest s O two source, So that is one of 365 00:22:32,720 --> 00:22:36,239 Speaker 1: the bad emissions. Other than that, not a whole lot 366 00:22:36,280 --> 00:22:40,400 Speaker 1: of really harmful emissions. No. UM. Most of the problems 367 00:22:40,440 --> 00:22:45,000 Speaker 1: that come from geothermal energy production come from the fact 368 00:22:45,040 --> 00:22:50,440 Speaker 1: that when you are harvesting hot water from these geothermal sources. UM. 369 00:22:50,560 --> 00:22:53,639 Speaker 1: Before they used to just pump it out. Yeah, that 370 00:22:53,720 --> 00:22:56,840 Speaker 1: was an open loop system, and they much anymore, and 371 00:22:56,920 --> 00:22:59,280 Speaker 1: they figured out that this is a huge waste of 372 00:22:59,320 --> 00:23:03,400 Speaker 1: a resource, right, so they started making clothed loop systems 373 00:23:03,440 --> 00:23:06,119 Speaker 1: where the water would be pumped out, it would be 374 00:23:06,240 --> 00:23:09,440 Speaker 1: used to say heat some other um fluid with a 375 00:23:09,520 --> 00:23:13,000 Speaker 1: lower boiling point or however you used it to to 376 00:23:13,119 --> 00:23:15,760 Speaker 1: make that turbine spin, and then the water would be 377 00:23:15,800 --> 00:23:18,600 Speaker 1: captured and then sent back down into the reservoir to 378 00:23:18,640 --> 00:23:22,119 Speaker 1: be reheated and used again. Super smart, It is very smart, 379 00:23:22,160 --> 00:23:24,679 Speaker 1: and in that case there's even fewer emissions than with 380 00:23:24,800 --> 00:23:28,199 Speaker 1: an open loop system. The problem is is that it 381 00:23:28,280 --> 00:23:33,120 Speaker 1: also leads to introduction of things like salts, sometimes arsenic, 382 00:23:33,280 --> 00:23:38,520 Speaker 1: other heavy metals into the groundwater supply UM once it 383 00:23:38,560 --> 00:23:41,040 Speaker 1: comes through and makes the cycle, So there's a there's 384 00:23:41,040 --> 00:23:45,000 Speaker 1: a threat to groundwater contamination. Using geothermal energy production. That's 385 00:23:45,000 --> 00:23:48,719 Speaker 1: one problem with it. Another one is those hotbeds that 386 00:23:48,760 --> 00:23:52,760 Speaker 1: are used that basically use fracking techniques. Just like with fracking, 387 00:23:53,000 --> 00:23:56,800 Speaker 1: they can cause things like earthquakes or like massive earth sinking. 388 00:23:56,840 --> 00:24:01,199 Speaker 1: There's probably a geothermal plant in Off, Autralia where the 389 00:24:01,280 --> 00:24:04,280 Speaker 1: area is sunk about five feet ever since it's been 390 00:24:04,320 --> 00:24:07,200 Speaker 1: in production. Wow. Yeah, because you're going in and you're 391 00:24:07,359 --> 00:24:09,640 Speaker 1: sucking out all the water, you're breaking up a bunch 392 00:24:09,640 --> 00:24:13,040 Speaker 1: of rocks that form bedrock. You know, so when you 393 00:24:13,040 --> 00:24:17,359 Speaker 1: start messing with that stuff, it can have seismic um repercussions. 394 00:24:18,160 --> 00:24:21,879 Speaker 1: That's a good band name. Thanks. Uh. Noise pollution is 395 00:24:21,920 --> 00:24:25,120 Speaker 1: on the plus side because they say it typically produces 396 00:24:25,200 --> 00:24:30,480 Speaker 1: less noise than the equivalent of leaves rustling from breeze. 397 00:24:30,800 --> 00:24:34,200 Speaker 1: Is not ba plus the the typical geothermal power plant 398 00:24:34,240 --> 00:24:37,000 Speaker 1: takes about a lot less real estate. Yeah, you can 399 00:24:37,040 --> 00:24:41,679 Speaker 1: do a vertical system, uh if it suits the area, 400 00:24:41,840 --> 00:24:44,600 Speaker 1: and that really doesn't use up much UM as far 401 00:24:44,640 --> 00:24:47,640 Speaker 1: as like spreading it out what's called service area because 402 00:24:47,680 --> 00:24:50,640 Speaker 1: it's going straight up and down. UM uses a lot 403 00:24:50,680 --> 00:24:54,080 Speaker 1: less water. Geothermal plant uses five gallons of freshwater per 404 00:24:54,119 --> 00:24:57,720 Speaker 1: megawatt hour. Compared to three hundred and sixty one gallons 405 00:24:57,720 --> 00:25:00,840 Speaker 1: by a natural gas facility. Isn't that ironic? It uses 406 00:25:00,920 --> 00:25:03,359 Speaker 1: less water even though water is the basis of the 407 00:25:03,400 --> 00:25:08,360 Speaker 1: whole thing. And apparently a binary air cool plants use 408 00:25:08,520 --> 00:25:12,119 Speaker 1: zero fresh water. Oh, it's all. It's all just down 409 00:25:12,200 --> 00:25:15,880 Speaker 1: from the from the earth. Yes. And for the land use, 410 00:25:15,960 --> 00:25:19,320 Speaker 1: I did have one more stat um over a thirty 411 00:25:19,400 --> 00:25:22,440 Speaker 1: year span, which is the time period they usually use 412 00:25:22,520 --> 00:25:25,480 Speaker 1: to consider like the big impact of a life cycle 413 00:25:25,520 --> 00:25:28,639 Speaker 1: of a system. Uh. They said, a geo thermal facility 414 00:25:28,720 --> 00:25:31,800 Speaker 1: uses four four square meters of land per gig about 415 00:25:31,840 --> 00:25:35,280 Speaker 1: our while coal uses three thousand, six hundred and thirty 416 00:25:35,320 --> 00:25:39,080 Speaker 1: two square meters per gigat hour. It's a big diff 417 00:25:39,920 --> 00:25:42,000 Speaker 1: I also saw that they had like a net energy 418 00:25:42,200 --> 00:25:46,879 Speaker 1: ratio of like four. For every like one input of 419 00:25:47,119 --> 00:25:52,040 Speaker 1: energy you get five, Yeah, which is really great. The 420 00:25:52,119 --> 00:25:55,240 Speaker 1: thing is, the upfront costs are very expensive. So in 421 00:25:55,280 --> 00:25:57,840 Speaker 1: a lot of places where it would be advantageous to 422 00:25:58,200 --> 00:26:02,680 Speaker 1: start a geo thermal energy production plant, they just don't 423 00:26:02,760 --> 00:26:04,920 Speaker 1: have the money to set up that kind of infrastructure. 424 00:26:04,920 --> 00:26:07,680 Speaker 1: It's anywhere from like one million to four million dollars 425 00:26:07,720 --> 00:26:10,919 Speaker 1: for a well to be drilled, and would say, like 426 00:26:10,960 --> 00:26:14,399 Speaker 1: a hot rock binary system, you need two wells at 427 00:26:14,480 --> 00:26:18,760 Speaker 1: least that's just for you know, one area, so that 428 00:26:18,880 --> 00:26:22,240 Speaker 1: the upfront cost can be prohibitive. And the same thing 429 00:26:22,320 --> 00:26:24,399 Speaker 1: goes for if you're setting up like a geo thermal 430 00:26:24,440 --> 00:26:27,040 Speaker 1: heat pump in your home too. Yeah, I think it's 431 00:26:27,080 --> 00:26:31,160 Speaker 1: pretty reasonable. Well, with government subsidies, it's super reasonable. Now 432 00:26:31,280 --> 00:26:34,520 Speaker 1: with the energy savings, they typically estimate the thing pays 433 00:26:34,560 --> 00:26:37,600 Speaker 1: for itself within like five years. Yeah. They for the 434 00:26:37,640 --> 00:26:41,280 Speaker 1: two thousand nine Economic Stimulus Recovery Act, they remove the 435 00:26:41,320 --> 00:26:44,959 Speaker 1: cap on heat pump system rebates, so now you can 436 00:26:45,000 --> 00:26:50,000 Speaker 1: get h towards a qualified geo thermal heat pump system. 437 00:26:50,080 --> 00:26:54,040 Speaker 1: So even the richie riches can make out. Uh So, 438 00:26:54,200 --> 00:26:55,920 Speaker 1: if you're looking at an average a typical home of 439 00:26:56,760 --> 00:27:01,800 Speaker 1: square feet, boy, that's a typical home. Geez, a heating 440 00:27:01,840 --> 00:27:05,359 Speaker 1: load of sixty to us in a cooling load of sixtus. 441 00:27:05,680 --> 00:27:12,320 Speaker 1: It's gonna cost about twenty grand to install yet uh back, 442 00:27:12,400 --> 00:27:14,679 Speaker 1: and that's about double the cost of conventional heating and 443 00:27:14,680 --> 00:27:20,560 Speaker 1: cooling hvac um. But it reduces your bill by and 444 00:27:21,440 --> 00:27:24,960 Speaker 1: at last eighteen to twenty three years, which is easily 445 00:27:25,000 --> 00:27:27,840 Speaker 1: double what your standard h BAC will cost, So you're 446 00:27:27,840 --> 00:27:31,080 Speaker 1: definitely gonna to make your money back UM if you 447 00:27:31,119 --> 00:27:34,600 Speaker 1: want to invest in something like this. Uh. It's also 448 00:27:34,720 --> 00:27:38,159 Speaker 1: better than wind and solar in many ways because you 449 00:27:38,200 --> 00:27:40,520 Speaker 1: don't have to rely on the sunshine or the wind 450 00:27:40,560 --> 00:27:44,960 Speaker 1: to blow. It's seven. That's the other thing. It's dependable. 451 00:27:45,040 --> 00:27:49,280 Speaker 1: It's also typically considered renewable, although they've figured out that UM. 452 00:27:49,359 --> 00:27:52,480 Speaker 1: You have to take measures to sustain a production plant, 453 00:27:52,520 --> 00:27:54,560 Speaker 1: Like you can't just pump all the water out. You 454 00:27:54,600 --> 00:27:57,439 Speaker 1: have to make a closed system. But even if you 455 00:27:57,480 --> 00:28:01,760 Speaker 1: do use a closed system like UM, the area can 456 00:28:01,880 --> 00:28:06,119 Speaker 1: cool off for well over time, like the one in 457 00:28:06,160 --> 00:28:12,320 Speaker 1: Italy has seen a reduction and steam power over since 458 00:28:12,359 --> 00:28:16,600 Speaker 1: the nineteen fifties because the geothermal reservoir beneath that has 459 00:28:16,640 --> 00:28:19,080 Speaker 1: been cooling. So you basically have to like take it 460 00:28:19,119 --> 00:28:21,119 Speaker 1: easy on it. You have to treat it like a 461 00:28:21,119 --> 00:28:24,080 Speaker 1: little gently, you know. Yeah, And apparently you can use 462 00:28:24,320 --> 00:28:27,760 Speaker 1: UM if you're putting in a system not just for 463 00:28:27,840 --> 00:28:30,800 Speaker 1: your home, but like a plant, it can other things 464 00:28:30,800 --> 00:28:34,159 Speaker 1: can be going on there. It can be a golf course, 465 00:28:34,200 --> 00:28:39,320 Speaker 1: it can be a horse trading facility. Sure, it can 466 00:28:39,360 --> 00:28:41,960 Speaker 1: be uh, what else is landis where it can be 467 00:28:42,000 --> 00:28:45,200 Speaker 1: a cemetery. Well maybe not a cemetery, yeah, because people 468 00:28:45,240 --> 00:28:47,520 Speaker 1: don't get buried below the frost line. They just get buried. 469 00:28:48,560 --> 00:28:52,560 Speaker 1: My family does. So there's addressing that. A lot of 470 00:28:52,560 --> 00:28:54,560 Speaker 1: people say, well, it just takes up too much land. 471 00:28:54,560 --> 00:28:56,840 Speaker 1: What if you don't have a lot of land. Um, 472 00:28:56,920 --> 00:28:59,760 Speaker 1: you can actually build a vertical system where the pipes 473 00:28:59,840 --> 00:29:02,960 Speaker 1: just go straight down rather than flat beneath your house 474 00:29:03,520 --> 00:29:07,800 Speaker 1: and you'll have the same effect. That's right. Uh. The 475 00:29:07,880 --> 00:29:10,520 Speaker 1: last thing I have here is the world's largest facility 476 00:29:11,320 --> 00:29:14,200 Speaker 1: called the Geysers. It's in San Francisco, right, Yeah, and 477 00:29:14,280 --> 00:29:18,120 Speaker 1: about seventy miles north of San Francisco in the Maya 478 00:29:18,160 --> 00:29:22,880 Speaker 1: Kamas Mountains, a company called Kalpine. It is forty square 479 00:29:22,920 --> 00:29:29,400 Speaker 1: miles long UM and it powers fourteen plants. And this 480 00:29:29,440 --> 00:29:32,080 Speaker 1: thing has been around for a while. This is not right. Uh, 481 00:29:32,160 --> 00:29:35,680 Speaker 1: seven five megawatts of electricity. It creates enough to power 482 00:29:35,760 --> 00:29:40,600 Speaker 1: seven homes or a city like San Francisco. So it 483 00:29:40,680 --> 00:29:43,360 Speaker 1: meets the power needs of Sonoma Lake in Medicino Counties 484 00:29:44,040 --> 00:29:48,240 Speaker 1: and UH portions of Marina and Napa, and satisfies almost 485 00:29:48,240 --> 00:29:52,280 Speaker 1: six of the average electricity demand in the North coast region. 486 00:29:52,600 --> 00:29:55,360 Speaker 1: That is the Golden great Bridge, Golden gate Bridge to Oregon. 487 00:29:55,560 --> 00:29:59,440 Speaker 1: Yeah't that crazy? That's so perfect for San Francisco. Man, 488 00:29:59,440 --> 00:30:03,960 Speaker 1: they're all over that stuff. That's great. You've got nothing 489 00:30:03,960 --> 00:30:07,000 Speaker 1: else huh no, man, uh man. My dad was an 490 00:30:07,120 --> 00:30:10,040 Speaker 1: hva C engineer. He'd be pretty proud of this one. Yeah, 491 00:30:10,640 --> 00:30:13,360 Speaker 1: you're gonna point it out to him, probably who probably 492 00:30:13,400 --> 00:30:15,840 Speaker 1: won't listen, but still, and he'd say, what's that show 493 00:30:15,880 --> 00:30:19,840 Speaker 1: you do again? If you want to know more about 494 00:30:19,880 --> 00:30:22,240 Speaker 1: geo thermal energy, you can take those words in the 495 00:30:22,240 --> 00:30:24,920 Speaker 1: search part how stuff works dot com? And I said 496 00:30:25,040 --> 00:30:27,880 Speaker 1: search bars somewhere in there, And that means it's time 497 00:30:27,920 --> 00:30:32,800 Speaker 1: for this movim. I'm gonna call this organ donation follow 498 00:30:32,880 --> 00:30:36,240 Speaker 1: up from an expert, as he says, Hey, guys, I'm 499 00:30:36,240 --> 00:30:39,600 Speaker 1: a donation specialist at an opi O, an organ procurement 500 00:30:39,680 --> 00:30:42,080 Speaker 1: organization in the Northeast. I've been doing it for about 501 00:30:42,120 --> 00:30:44,160 Speaker 1: eight years. Uh. And the biggest concern I had with 502 00:30:44,200 --> 00:30:47,280 Speaker 1: your show was how tissue donation was incorrectly grouped together 503 00:30:47,280 --> 00:30:50,440 Speaker 1: with whole body donation. They're definitely not the same thing. 504 00:30:51,120 --> 00:30:54,480 Speaker 1: Body donation for science research is completely different than tissue 505 00:30:54,480 --> 00:30:57,960 Speaker 1: donation for transplant. A tissue donation should be and is 506 00:30:58,000 --> 00:31:02,400 Speaker 1: grouped together with organ donation. UH. Bone, skin, cornea, heart valve, 507 00:31:02,400 --> 00:31:05,560 Speaker 1: and vascular tissue are both life saving and life enhancing 508 00:31:05,560 --> 00:31:08,480 Speaker 1: gifts meant for recipients. In fact, when you register to 509 00:31:08,480 --> 00:31:11,440 Speaker 1: be a donor d m B or an online database, 510 00:31:11,440 --> 00:31:14,200 Speaker 1: you're registering is an organ and tissue donor, not a 511 00:31:14,240 --> 00:31:18,160 Speaker 1: whole body donor. Secondly, there absolutely is federal oversight regulation 512 00:31:18,600 --> 00:31:21,360 Speaker 1: and protocol for tissue Uh. The f d A A 513 00:31:21,360 --> 00:31:25,960 Speaker 1: A t B American Association of Tissue Banks. I but 514 00:31:26,160 --> 00:31:30,960 Speaker 1: that's a fun uh conference. Yeah conference. Uh. The e 515 00:31:31,080 --> 00:31:33,280 Speaker 1: B a A, the I Bank Association of America or 516 00:31:33,320 --> 00:31:36,000 Speaker 1: some of those governing bodies opos and tissue banks are 517 00:31:36,000 --> 00:31:41,560 Speaker 1: held to strict standards, including site visits and annual audits. UH. Lastly, 518 00:31:41,600 --> 00:31:43,960 Speaker 1: I encourage you both to do some further research into 519 00:31:44,040 --> 00:31:47,080 Speaker 1: tissue donation and be careful not to perpetuate into ex 520 00:31:47,120 --> 00:31:54,960 Speaker 1: stereotypes and misconceptions. Uh. Those This is from Josh Brennan, 521 00:31:55,880 --> 00:31:58,240 Speaker 1: and another guy wrote in and was like, I see 522 00:31:58,240 --> 00:32:01,440 Speaker 1: where Josh is going, but he's got it backwards. He said, 523 00:32:02,480 --> 00:32:06,440 Speaker 1: there's too much regulation on the organ side. Seven thousand 524 00:32:06,480 --> 00:32:09,320 Speaker 1: people year die because of the overregulation, and they need 525 00:32:09,320 --> 00:32:13,320 Speaker 1: to make it all for money. Disagree, And he wasn't. 526 00:32:13,360 --> 00:32:16,080 Speaker 1: He was like, he sourced a bunch of academic He's like, 527 00:32:16,120 --> 00:32:18,840 Speaker 1: the medical and academic communities are the ones making the 528 00:32:18,880 --> 00:32:21,040 Speaker 1: call for this. It's like, it's not like a bunch 529 00:32:21,040 --> 00:32:24,800 Speaker 1: of you know, free market Zella's. Trump's not calling for it. No, 530 00:32:25,000 --> 00:32:27,920 Speaker 1: he was like, doctors and scientists are saying this is 531 00:32:27,960 --> 00:32:30,280 Speaker 1: how it should go. Um. I guess that the reason 532 00:32:30,400 --> 00:32:33,240 Speaker 1: I saw fit to lump those things in together is 533 00:32:33,280 --> 00:32:35,160 Speaker 1: because I saw that one of the outcome from the 534 00:32:35,200 --> 00:32:38,600 Speaker 1: whole body donation could be the harvesting of your parts 535 00:32:39,120 --> 00:32:42,520 Speaker 1: for sale. And that's well that happens from times. That's 536 00:32:42,560 --> 00:32:45,440 Speaker 1: what illegal or illegal or gray market. Yeah, that's what 537 00:32:45,520 --> 00:32:48,760 Speaker 1: the guy, the first guy said, is the gray market 538 00:32:48,800 --> 00:32:51,800 Speaker 1: is there because it's so heavily regulated. People are dying 539 00:32:52,400 --> 00:32:54,680 Speaker 1: because they can't get this stuff, so they're willing to 540 00:32:54,680 --> 00:32:57,680 Speaker 1: go pay. He said, if you take out the if 541 00:32:57,680 --> 00:33:00,400 Speaker 1: you give the demand, that illegal supply will have to 542 00:33:00,400 --> 00:33:02,880 Speaker 1: be there. Yeah, I mean maybe maybe that's the case 543 00:33:02,920 --> 00:33:05,240 Speaker 1: as well, but yeah, I don't know. I think that 544 00:33:05,560 --> 00:33:07,280 Speaker 1: I think they're doing a great job with the Oregon 545 00:33:07,320 --> 00:33:09,960 Speaker 1: Pro Human thing, aside from the seven thousand people that 546 00:33:10,000 --> 00:33:15,280 Speaker 1: are trying every year waiting.
