Well so this is my colleague. Sarah rieger she's a reporter in calgary and after receiving a tip. She started digging into noise complaints from a wealthy community near edmonton. Some people thought it was. It was some kind of farm equipment. Some people thought it was some other kind of equipment and you have a hot tub in the back. We go sit and go. Hey what is that airplane landing in our field. What i seemed like a normal neighborhood. Squabble about keeping the volume down soon involves secretly constructed powerplants big financial technology and the future of alberta's energy infrastructure. It all started in the fall of last year. When some residents of sturgeon county complained about that sound that she was describing as you can imagine a constant buzzing noises pretty frustrating so they say not only.

The Electric Grid-Lock
"Robinson. Mayer is a writer at the atlantic and author of the newsletter. The weekly planet so robinson. Let's turn up very basically How is the power grid in the. Us organized nationals state by state. Oh well it's it's a disaster honest basically. There's three grids in the us. There is the eastern grid which kind of runs to the middle of the country. There's the westerner connect and then there's texas and we are just going to set x aside. So here's the thing. All the grids within those big interconnections like talk to each other and are connected so you could move electricity from like connecticut to new york to new jersey even though those are kind of like three different local grids. Yeah but like. You can't move electricity super easily from oklahoma to new jersey. The dream of a national grid is that you build those across the country so that we have like basically like an electricity interstate highway system linking the whole country. What is so bad about the current situation. I mean what would actually be so much better if everything were fixed and perfect like i dunno with power bills be like a quarter as expensive. Would they be like a couple of bucks. Plus would it be like our carbon emissions would go down by eighty percent. I mean what are the stakes here. The stakes here. I think are really two fold. The first is gonna need transmission to solve climate change. We just need it. that is blowing. My mind is not that big of a deal transmission. It's really so. It's a huge deal to fight. Climate change right. We need to build as much low-carbon electricity generation as possible right as many renewables and so it is just true that we have a power system that right now. Basically relies on kind of power plants to generate electricity. A lot of the time and we're moving to a power system where we have to be kind of more entrepreneurial about where electricity is flowing from anyone moment

It's actually interwoven with the story. Whether or not tesla's paying for any of this or if the game just wanted to have tesla in it is not clear. Next year is an event to be on the lookout for from elon. This wednesday alone will be participating in the b word. Bitcoin conference as we previously talked about.

Kathy of course of arc invest and both jack and kathy are big supporters of bitcoin whereas yulon has obviously said that he is a supporter of bitcoin in the past but has also made critical comments about bitcoin since then which has garnered a harsh reaction. Let's say from the bitcoin community so it'll be really interesting to hear that discussion obviously is going to receive a lot of media as well. I wouldn't expect a ton of overlapping. Commentary on tesla other than the information that we already know which would be tussles position and the reason they took that position having a highly liquid assets that could still appreciate no longer accepting transactions because of high environmental costs etc. But we'll see. i guess.

Literacy for Environmental Justice
"I'm joined remotely via soon by the andrea morton senior development consulting community program coordinator alex lasco and executive director. Patrick marley rump. From literacy for environmental justice. Thanks for being here. The entry alex and patrick thank you very very much and then patrick i'm gonna turn to you and ask you to please provide the audience. A quick overview of who is literacy for environmental justice environmental justice or ledge is a community based grassroots nonprofit in bayview hunters point or district in southeastern francisco. Were basically like a combination of young adults youth. Educators activists environmentalists. You know have come together to kinda create environmental justice and social change. Big one hundred point. Our organization was founded in nineteen ninety eight and it was really at that time and bayview. There was a lot of work around closing the hunters point. Pg power plant illuminating all the stuff the not in my backyard stuff that exists and baby. There's three hundred twenty five toxic sites and one hundred point and really. I think there was a strong movement to address the environmental injustices. An impact on the bayview hunters point community. But there really wasn't a mechanism to engage you so our founding director paired up with some youth and high school and came up with the idea of creating a organization were projects that could bridge the gap between the advocacy of the elders and the next generation. So while we got our beginnings and really like teaching the principles of environmental justice and providing a platform for young people to be a part of the environmental justice who had been at a localized level. I think our organization has kind of spun out to actually create some of the just environments that we want so we've done extensive work with the san francisco unified school district to bring people to the community to do investigation to habitat restoration to transform spaces cairns at park to build the aeko center at herron said are and last like decade.

They're heading down to the greenwich generation. Power plant the natural gas-fired facility generates some electricity. Oh what's gotten. The attention of. The activists is their generation of bitcoin. They're protesting today. Because greenwich is looking to expand. Its bitcoin mining. That would probably mean burning. More natural gas emitting more greenhouse gases. Yvonne taylor is vice. President of seneca lake guardian and is leading the opposition to greenwich. We simply cannot allow this ludicrous scheme of burning fossil fuels to make fake money in the midst of climate generating or mining. Cryptocurrency is complicated. there's no actual mining the gist.

A Look Back at What Caused the Chernobyl Disaster
"1 of the worst disasters in history happened. It was a Saturday in the early morning when reactor number four at the Chernobyl nuclear power plant exploded in what is now Ukraine. Ironically, the incident started during a safety test. It was supposed to be a simulation of an electrical power outage and to test the cooling function to keep the reactor stable. A combination of dangerous conditions and design flaws led to an uncontrolled nuclear chain reaction. It was considered the worst nuclear disaster in history in terms of cost and casualties. It's one of only two nuclear accidents that has been raided a seven, which is the highest disaster level on the rating scale. Today, Chernobyl is a ghost town labeled the Zone of alienation. All because of the major disaster on this day in 1986. You know, I watch all those

We get more on the promised emission cuts by the president from Mike Power and analysis by energy innovation found that for the U. S to achieve the greenhouse gas emissions goals set forth by President Biden, we would have to phase out all of our remaining coal power plants and have our natural gas use over the next decade. We would also have to dramatically increase our energy efficiency and electrified vehicles. The analysis won't lay out of figure for the outlay but estimates that these job changes would add $570 billion per year to the U. S economy vehicle.

How Will Biden Administration Reach Its Clean Energy Goal?
"President biden's administration said a big climate goal two zero out greenhouse gas emissions from power plants by twenty thirty five last week we talked with epa administrator michael regan about this believe that we can set up the right policy instrumentation and regulatory framework to encourage continued innovation to get us to that carbon-neutral goal that we know we can't achieve continued innovation. Industries still has to figure some of this out. So what more do we know about how the government is going to encourage it. Npr's jeff brady has been following up. Jeff good morning good morning. I just wanna know. 2035 sounds really distant. And then you start counting fourteen years not that long when you talk about changing all the power plants in the country house administration going to do it. Well you know is getting. The details are getting a little bit clear from the president's budget proposal and groups talking with the administration about this Details are still being worked out but a central focus is creating a national clean energy standard. And this would be a countrywide requirement that overtime increasing of is generated from fuels that don't emit the greenhouse gases that fossil fuels do conrad schneider at the clean air task. Force says it's similar to renewable energy standards that many states have they essentially required an increasing percentage electricity sales from renewable energy like clean energy standard simply broadens the list of energy resources that are eligible under the standard so in addition to wind and solar. This national standard would include things like hydropower and nuclear and another bit of detail. Here of energy likely will create this standard. And that's a little controversial.

Using Dragonflies as Contamination Detectors
"Mercury pollution from power plants and mining operations can end up in our air and water. But it's tricky to predict. Just how much of that. Environmental mercury will make its way into our food and our bodies we were working on developing a bio indicator of sent. And all that could inform us of the levels of mercury contamination across the us ecologist colin eagles smith of the united states survey. He and his colleagues came up with a practical way to determine the scope of mercury contamination in an ecosystem by measuring mercury levels in a single species their bio indicator juvenile dragonflies or larvae dragonfly larvae. Stander water don't move. Much are easy to collect and live long enough to accumulate significant amounts of mercury. If you have enough location sampled with dragonflies you can develop an index of of the relative amount of mercury in the biological community. The team measured mercury concentrations in thousands of dragonfly larvae collected from waterways. One hundred national parks during a ten year period and to amass the large sample number. They recruited volunteers through the dragonfly. Mercury project the volunteers used dip nets to collect dragonfly. Larvae from their aquatic national park staff then sent the larvae to laboratories for processing

"power plant" Discussed on TechStuff
"It's really hard to build new nuclear power plants, even though they currently produce about twenty percent of the electricity that the United States uses. So eventually, if those all those power plants go dark, you gotta figure out where that twenty percent is gonna come from because our demand for electricity isn't going down. It's going up every year. So that puts a huge pressure on us to figure out where else are we going to get this electric city. And the easiest answer is fossil fuels, but we already know fossil fuels contribute to climate change. They produce pollutants that are environmental and health hazards. So not a great story. Now it's easier to store. Low level waste that stuff. I was telling you about where it's the equipment or the uniforms as stuff like that stuff that was in the power plant and absorbed radiation over time. But those materials pose much less of a threat than spent nuclear fuel. They will tend to have their radiation completely diminished within three hundred years, which is still a long time, but a heck of a lot shorter than tens of thousands of years. And again, like I said, some of the most hazardous radioactive materials have a half life of around ten years or less, but not all of them do. And that's the problem. So telling someone, hey, within twenty years, most of the stuff won't even be a problem anymore isn't necessarily the biggest winning argument. You can make to someone when you're trying to store nuclear waste there. In addition to all that building nuclear power plants became economically challenging. It's very expensive to build one, not just because the technology is sophisticated and complicated and you've got to have a lot of materials, but also. There's a lot of bureaucracy surrounding the process. Not that the bureaucracy doesn't serve a purpose. They're very strict protections and regulations that are in place to require facilities to be built an operate under safe guidelines. Those are absolutely necessary. There's a history of of facilities that were not operating up to those guidelines and that is not just criminal, but potentially deadly. So those regulations and restrictions end up adding to the cost, obviously. And while nuclear power has compelling positive arguments compared to again, like coal power plants might make more economic sense to look elsewhere if you're getting into the energy biz. And then of course, we have the famous disasters stuff like Three Mile Island, tra-, noble and Cosima. And as I said, I'm going to do an episode soon that explains what happened in each of those three cases and what we learned as a result of those. But they certainly have gone a long way to discourage support for nuclear power. If you can point to a disaster. That's a pretty powerful con argument. And earlier I mentioned thorium reactors as a proposed alternative to the traditional YouTube thirty-five ones. These reactors wouldn't use thorium itself for fuel. Rather a facility would process th Aurium to thirty two and create an isotope called uranium to thirty three uranium to thirty three's unstable. You will not find it out in nature, but it is fissile meaning like you to thirty five. You can create a sustained nuclear reaction using this. Fuel. In addition proponents say, thorium based plants would produce less nuclear waste. There would be more efficient at producing energy and thorium is more plentiful than uranium now have to do a full episode about thorium implants, but that's further in the future. I'm not gonna do more than one week of nuclear power stories at a time. I'll I'll revisit that, but here's one fun, local facts, something that you guys can look forward to. I learned that and. I'm amazed that never heard this before, but I live within an hour of a radiated site that I learned about this in a book titled atomic awakening by James Mahaffy and the radiated site is now known as the Dawson forest wildlife area. That's about fifty miles north of Atlanta, the city where I live and formerly, this was the Georgia nuclear aircraft laboratory, which was a top secret are indeed facility operated by the air force and the story behind it is really interesting. And I think I'm actually going to take a little trip with the guys from us stuff. They don't want you to know and we're all going to visit it with Geiger counters. So stay tuned for that..

"Because the energy from a nuclear reactor includes stuff that can really cause harm to humans in various ways. The nuclear reactor itself has to be heavily shielded to prevent that radiation from getting out into the general environment. Typically reactor has a concrete liner to act as a radiation shield and around that liner. So one layer out think of it as an onion. So you've got a reactor at the core of the onion. You've got appeal of the onion, a layer of the that is the concrete liner. Then you have another layer around that. That's a steel containment vessel. And then the power plant itself is typically made out of very thick concrete that acts as sort of a final layer of protection between the reactor and the surrounding area. If all else were to fail. In addition, the spent fuel inefficient reactor is itself radioactive. It contains a lot of different radioactive materials in it of various. Half life's so some of those half life's are on the matter of days or a couple of years. But others last a lot longer the equipment and parts of a nuclear power plant can absorb energy and become reactive as well. That is what we call low level radioactive material or radioactive waste that is much lower in radio activity and in potential danger than say, spent fuel is, but however this creates challenges when it comes to what do you do with that stuff? What do you do with this waste? It's still dangerous. It emits a lot of energy. It will eventually corrode whatever container you put it into, and it will stay dangerous for thousands of years in some cases, tens of thousands with high level radiation and indicates very slowly into stable forms. They'll do so long after we're gone. Keep in mind, ten thousand years. That's the length of human history. So. So this waste, some of it will remain dangerously radioactive as in the type of radiation it gives off could cause harm for thousands of years. The most dangerous stuff tends to decay much faster, but it's not really that reassuring. So we have to figure out what do we do with the stuff, nuclear power plants produce about two thousand metric, tons of nuclear waste every year back in the nineteen sixties. One plan for dealing with waste involved reprocessing the nuclear waste in order to produce new fuel. And one of those products of reprocessing is plutonium and plutonium two thirty eight can be used as a nuclear fuel. You make it by bombarding uranium to thirty eight with neutrons..

"So in some reactors, like the third of the ones that are in the United States, the coolant is in fact the water that gets converted into steam and eventually pushes a turbine. But again, that can be risky because that coolant has been in direct contact with the radioactive materials. So if that's. Steam were to escape him, then that could be a potential hazard for the surrounding environment. Generally, most of the power plants in the United States use pressurized water reactors and a secondary closed system of water for the purposes of turning the turbines, two thirds of the power plants, the United States use this approach. So you have the water, the coolant that's inside your nuclear reactor under tremendous amount of pressure and that pressure prevents the water from boiling off. It remains liquid, so it's superheated liquid. That cannot boil because of that pressure that superheated liquid is in contact with a heat exchanger. And the heat exchanger transfers heat to the water that's inside a boiler, and that water can boil off turned into steam and turn steam turbines, but it's in its own closed parallel system. So the two systems don't actually share. Any water between the two of them and that way you have one relatively clean system of water that's consistently being heated to steam turning turbines condensing back into water and starting over again. And then you have the other one that's acting as the coolant for your actual reactor. Two thirds of the power plants in the United States use that approach the steam that powers the turbine has to cool off in order to condense back into water. So some plants will use water from natural resources like lakes or streams to cool that steam using another form of heat exchange. So the steam exchanges heat, it transfers heat to the water from the lake or stream. And then as a result, the steam itself starts to cool down because it's pushed that heat energy off to a different source and turns into water other nuclear power plants have those really tall cooling towers. Those are those icon ick enormous chimney like structures that we tend to associate with nuclear power plants. Like if you watch. The Simpsons. You see that that icon ick shape of the cooling towers next to the power plant in in Springfield. So for every unit of electricity produced by power plant about two units of waste heat, get transferred to the environment, but that's just heat, it's it is heat, but it's not greenhouse gas. So it's not something that contributes to climate change on a global scale. You get some regionalized heating, but it's temporary. So that's good, but nuclear power plants, obviously create some real challenges. What are those? Well, I'll tell you in just a second, but first, let's take another quick break to think our sponsor.

"A high energy photons. In addition, the two new atoms that result from the vision of uranium-235 will undergo beta radiation, which means they release super fast electrons, and they also released more gamma radiation against has pretty dangerous stuff. It will not turn you into the hook. It will hurt you very badly. So let's talk about the innards of a nuclear reactor. So you gotta get a source. Of uranium-235 enriched uranium to thirty five. That means that there's a higher concentration of uranium-235 in your amount of uranium than you would find in nature. So if you went out in nature, you got yourself a pick and you're going to an area that's rich in uranium and you mind yourself some uranium and you get a big chunk of uranium. Most of the atoms of that uranium are going to be you to thirty eight. Almost all of them uranium-235 would make up about point seven, two percent of all the atoms. In that sample you collected then is not enough for you to be able to hit critical mass. You need to be at around two or three percent uranium-235 in the overall sample in order to have that sustainable nuclear reaction, which means you have to have enriched uranium. You had to have uranium has unnaturally high concentrations of uranium-235 and you form these samples of enriched uranium into. Pellets. Each pellet is a cylinder that's about two and a half centimeters long or about an inch long. They have a diameter of around eighteen millimetres around point seven inches. So in other words, there about the diameter of a US dime, and you take these little cylinder Lindros pellets, and you put them end to end to form rods, uranium rods. You then collect bunches of those rods into what are called bundles. The bundles you put into a pressure vessel that's filled with water and the water acts as your coolant these nuclear reactions generate a lot of heat and without a coolant that amount of heat would be high enough to actually melt the rods themselves. The rods would overheat through these reactions and we'll get hotter than the melting point for uranium. This is what we in the biz call a nuclear meltdown, and it is a bad thing to have happen. So you have to have that coolant there. Another preventative measure against overheating. Are the control rods, control rods are made of a material that can absorb neutrons. Now, remember the sustained nuclear reaction of a nuclear power plant involves uranium-235 emitting these neutrons and then absorbing incoming neutrons emitting splitting emitting more neutrons. And that's what keeps the reaction going. So if you put in material that can absorb those neutrons, you're taking away the trigger that would continue to allow this nuclear reaction to happen. So you can actually use these robotic arms to lower or raise the control rods out of the bundles of uranium two thirty five. And by by putting them into the bundles, you absorb more of those neutrons. So you can reduce the rate of nuclear reaction. You can even stop it completely. If you if you leave it in there long enough and you have enough of the the, the control rods there, or you can lift it out of the bundles to allow more of. Of those reactions to occur to increase the reactions and it all depends on how things are going on in the core at any given time. And if the reactions ramping up too quickly lower arrived in the bundle soak up some neutrons, prevent those U2. thirty five atoms in the bundles from doing it and pushing the reaction even further. Now in some reactors, the coolant isn't water at all. It might be something else. There are a few that use gas based coolants like carbon dioxide, or they might use liquid metals, like sodium or potassium that generally allows you to operate at a higher temperature than you would if you're using water. But that also could mean that you're burning through fuel a lot faster..

"Now the steam continues through the system after passing through the turbine, and it cools down as it does. So typically through exposure to some other part of this system and as it cools down. Down at condenses back into water, and it flows back into the boiler where the whole process can start over again. But again, with nuclear power, you're using a different material and process to create the heat than you would with a coal power plant, and there's a need to make sure the systems in a nuclear power plant are secure and separate from each other to prevent contamination or at least shielded very, very well if you have a full implemented system. So if the water is actually passing through the reactor and that same water is the water that's converted into steam the best with the turbine, we want to make sure that that facility is very well shielded. Most nuclear power plants have to water systems. They have one that's the coolant and then they have a secondary one where there's a heat exchanger that sends the heat from the coolant into this boiler, which then boils off the water and create steam, and the the two systems are separate. They don't. They don't come. Into direct contact with each other. So you don't pass radioactive contaminants from the coolant into the steam that you're using to turn the turbines. Now, the isotope most commonly associated with nuclear power is uranium two, thirty five, but plutonium two thirty. Nine is also used in some reactors, and there are some nuclear power proponents who really advocate a thorium based power plant more on that later in this episode and I've said the word isotope, if you times was that actually, meanwhile isotopes are two or more forms of the same element meaning two or more forms that all have the same number of protons because if you have different number of protons and you have different elements, so you're looking at two different atoms that represent the same element and they had the same number of protons, but they have different numbers of neutrons from each other. Neutrons. Are particles have a neutral charge. You find them in the nuclei of atoms. They don't affect the chemical properties. Of the element, but isotopes do have different atomic masses relative to one another. So they are chemically identical. But from a nuclear process perspective, they are different. So uranium-235 is as you would imagine an isotope of uranium it is not the most commonly found form of uranium in nature. The most common form of uranium is uranium two thirty eight uranium to thirty eight has ninety two protons and one hundred forty, six neutrons. Uranium-235 has ninety two protons and one forty. Three neutrons. Uranium-235 makes up less than one percent of all naturally occurring uranium in the world. And it has a half-life of nearly seven hundred four million years which means if you have a quantity of uranium to thirty-five any given amount. Let's say that you have a pound of uranium-235. That's an enormous amount of Gary name to thirty five. But let's say you have a pound of it. It would take approximately seven hundred four million years for that uranium-235 to reduce in half through radioactive decay. So you would end up with half a pound on average after seven hundred four million years more or less the this is essentially the the rate of radioactive decay. But I think we could actually do a lot better than that if we really put our minds to it, knocks plane how in just a second. But first, let's take a quick break to thank our sponsor.
