- Nuclear energy might have a lot of unused potential. Not only is it one of the best mid term solutions for global warming bit despite what gut feeling tells us, it has saved millions of lives. By investing more into better technologies we might be able to make nuclear energy finally save and clean forever.

The bad arguments said nothing about Thorium.And since it is safer than uranium i think the answer is obvious!
no ur bad
do video why i got bones
There was 1 dead by fukushima
read my comment
You should probably have pointed out that cooling towers in nuclear plants only emit water vapor (H2O). You'd be surprised at how much people (at least here in my country) believe that "radioactive stuff" comes out of the "chimneys".
I agree blazer some people don't know what they are talking about
xD
In what country do you live?
What is a cubicwatt
Also, citation?
So we have been working on this project for more than a year on and off. now The only way we found to be really neutral was not to be neutral. We did a pro and contra video - the pro video is *really* pro, the contra video is *really* contra. Together they should even out and become a neutral statement. So before you write angry comments about how we totally did misrepresent nuclear energy, please watch both of them. And share them if you like them!
very nice i really think everyone who knows what he is talking about should be "for" nuclear energy
***** great job trying to balance the arguments on facts
kurojima i really think the favor is for nuclear
***** You guys are great about being scientifically accurate, but in the future could you refer to global warming as "climate change" as it is not JUST the warming of the earth.
ttam 809 But it is global warming. The dominant trend in climate change is the warming of the climate. The changes that are occurring are because the climate is warming.
As a German I can tell you that closing many nuclear plants in favor of coal was a very dumb idea. Sure we have invested plenty in renewable eneregy, but these sources aren't reliable to maintain the electric frequency of the power lines at 50 Hz, so when there's no wind or sun, coal is our only main option. Meanwhile in France they have 70% I believe of their electricity produced with nuclear energy, it's the cleanest country (at least CO2 wise) in Europe with Norway.
I’ve heard of that stupid protesters protested the nuclear power plants and then you guys replaced them with lignite. Coal but worse
Yeah, politicians know that pretending to care about climate change is much better than actually doing things, so since people think nuclear is bad, they just close them and make the problem worse. In France, they just closed part of Fessenheim nuclear power plant for no reason.
Well, there are gas power plants as well, which are way more flexible than coal p.p. and produce less CO2. Unfortunately, our german government is too incompetent to follow countries like England who have completed such a process already and accordingly have a much better emission record. But, yeah, the timing of the phase-out of nuclear power was horrible with regards to what climate protection would require. It simply was a rash, populist decision at the time. Anyway, building more nuclear p.p. now wouldn't solve the problem either because planning, waiting for approval, building and commissioning would take roughly 20-30 years. But we need low-carbon electricity generation now, not in 30 years. Also, the political climate makes it practically impossible to pursue nuclear energy in Germany.
When there won't be anymore poor suckers that'll get paid for burying your nuclear waste, you'll be happy you got rid of them. Nuclear waste will be poisoning future generations for thousands of years.
@@paulalexandre3358 not for no reason, but because of Germany and Switzerland! They forced us to close Fessenheim !
Before watching this video I was one of those pepole who are against nuclear energy due to ignorance and its bad reputation.
but now I think it's our best option until renewable or fusion will take off.
Thanks Kurzgesagt for enlightening me
*fission not fusion
no, they meant fusion
@@DomWPC oh sorry i didn't read the comment properly.
@@mosqou yeah? so what?
@Zangief The Red how is it so bad then? its the best option up until we get nuclear fusion, and thorium reactors are even better then uranium or plutonium and doesnt need to be refined, also its not a well earned reputation, its just chernoble was due to a poorly made reactore, human negligence, and fukishima couldve also been avoided due to the fact that they shouldve seen an earthquake was prone to happen due to the fact that it is an earthquake prone area and also it was a 9.0, unordinarily high earthquake and very rare. if you think nuclear energy is bad, please explain why.
I really hope we develop Thorium reactors.
***** Ok. Last thing i heared there were no thorium reactors yet.
*****
Those are CANDU reactors I think. They can even run on LWR waste, but not as much energy as a breeder.
Paul S
Actually, the first working prototype was made back in the 70's when people were deciding on which path to go with, Thorium or Uranium. They choose Uranium simply because the byproduct of it was Plutonium which can be used in military, while the with Thorium you don't really have any byproduct other than smaller and smaller chunks of Thorium. The project was chucked for a long time and since the only working prototype is in US and they're not willing to share it, this technology path has been forgotten till recently.
Ivan Hrenovac
They are sharing the info right now with a canadian company, terrestrial energy. It doesn't look like a LFTR though.
Yeah, "we". More like us engineers and scientists.
I just read up about Thorium reactors... why the hell is this receiving minimal funding?
+Soulless Jack It is called Iter.
+Omeggia Monopoly of evergy market most likely

+DeadPistolsBrainGerms You're an idiot.
Some people are afraid of progress
Thorium reactors sound pretty badass.
It'll take multiple decades to get politics rolling on implementation of that technology, though.
The problem is that we don't have that time anymore since the climate is already fucked up. We can't wait another 30 years when we should have gotten rid of fossil fuel usage 30 years ago.
Orillion123456 Well then it sounds like the best we can hope for is mitigating the disaster at this point. Our forbears dealt us a shitty hand so now we have to play it.
Those damn hippies back then should have informed themselves before protesting against nuclear energy. A big reason why we didn't get rid of it is money. Why should the rich part of humanity spend more money on saving the earth when they can earn even more money by not doing anything?
Yeah it does!
that's why its called "thor"-ium cause thor is badass too

iSoTz & highdopvp ⌉ PvP faction ⌈ but France this summer has stopped and decrease power of many reactors due to warming and lack of water to cool down the reactors. And many of them are in the ending of their lifetime and dangerously old. Decomissioning will cost more than waht needed to built.
thought it was 80% now? anyways, your doing better then the idiots i have to deal with in the US. stupid people think solar and wind power are better then the evil radiation producers, ya know its not like nuclear reactors put less radiation into the environment then coal power. no thats obviously not true!
@@notlogical4016 It's 72% while in 1995 ,it was 74%
Watching the contra video: "Nuclear power got to go!"
Watching the pro video: "Nuclear power actually sounds pretty good.."
Really? Because from the sounds of it. For a nuclear standpoint, this is at least 95% favorable towards nuclear energy.
Huh. weird. I swear some of the facts in the contra video directly contradict the facts in the pro video.
Really, I thought some of the contra theories were disproved by the pro theories.
Watching the contra video again: "Nuclear power got to go!"
I thought they exaggerated the dangers a bit. Nuclear disasters like the one in Fukushima were always caused by stupid and easily preventable human mistakes or unsafe reactors. These things won't happen in Europe were there are strict regulations and no corruption. Nuclear waste is the only small problem, which could've been solved years ago if ignorant hippies wouldn't protest nuclear power and stop research.
"Nuclear energy is arguably less harmful to environment than fossil fuels".
Correction: "Nuclear energy is INDISPUTABLY less harmful to the environment than fossil fuels."
@Gavin Gamble not every energy source is perfect. We still don’t have a permanent long-term solution for nuclear waste.
@@harrisonkarn2078 Yes we do. You obviously know nothing about physics. I’m a physics major. Nuclear waste is small and manageable and most of it is just stored on site. France has even started reusing their own nuclear waste.
@@harrisonkarn2078 Deinococcus radiodurans is a polyextremophilic bacteria that is chemoorganotrophic (relying not on food but on radiation). This means that nuclear waste can be treated by this thing since genetic engineering allowed it to digest solvents & heavy metals in radioactive environments
@@maxwell8758 they used deinococcus bacteria family?
Not only that, but even if there's a meltdown somehow radiation leaks, the containment zone is actually a paradise for wild life. 😁
i watched the anti nuclear energy first, and then this one. the anti made me think that nuclear energy maybe wasn't a good idea after all, but this video quickly changed my mind again. so i'd say that these videos did exactly what they're supposed to do.
Huntracony If more people started in the middle for nuclear and other issues like climate change, i think the conversation would be a whole lot better. Glad to see these videos are doing just that.
Christopher Willis i have a lot of people around me against nuclear energy, so i guess that kept me in the middle too.
Aguila701 yep
***** I wish life was magical, but i think this is as close to a miracle solution as we'll get. If you want to generate a lot of energy in one place, it will always be relatively dangerous, and if you want to spread it out, it will always stupidly expensive.
I hope that i'm proven wrong about this.
Huntracony ***** My goal, as a future nuclear engineer, is to design reactor systems that are basically boring. As boring as that highly dangerous but super well engineered lithium ion battery you hold up to your face everyday :D
Number 2 is basically my argument in favor of Nuclear energy
It's not something we want to keep forever, but it's better then what we're currently using
For long term energy usage, I'm currently very intrigued by geothermal, I know a guy who has a neighbor that has geothermal air conditioning/heating, and he won't shut up about the money it saves him
It's actually kind of annoying
I would argue geothermal is probably better than nuclear. But so far nuclear is one of the best ways to do things. Solar and wind is very limited and batteries used to store energy that isn't immediately used is very toxic. If we don't use batteries, we still need alternate power to make up for the down times these systems get. Hydro is also pretty good but considering that it have other major environmental effects, Nuclear sounds the best. Particularly the 4th generation thorium reactors with minimal waste production relative to the current ones.
If we can get nuclear fusion ready, that would be even better. Even cleaner, less catastrophic risk and even more power.
Deathnotefan97 geothermal is for primitives. Nuclear fusion is the fusion
alternative nuclear energy sounds like the best option. The arguments are definitely compelling against nuclear energy in it's current state but if we just had technology to automate it we wouldn't have incompetency to cause meltdowns and uninhabitable areas of land and it'd be less harmful to the environment. If we had nuclear accidents every 10 or 30 years eventually the amount of uninhabitable land would exponentially increase deaths as population density becomes larger and there's less land to inhabit.
you know that the inside of the earth has only stayed this warm for so long because of radioactive decay.
I would argue geothermal is dumb since its slowly(very;0) cooling down the Earth's core which would lead to our demise heh
I've never understood why the green party prefers fossil fuels over nuclear. For me global warming always seemed like a more pressing problem than nuclear waste storage.
Karlo Schallibaum Which green party are you on about?
softrockification The one in Germany. The one that caused a boom in coal energy.
Same deal with the 'green' party (and like 80% of the rest parties) in Sweden, they speak about Nuclear power like it's the most dangerous thing in the world and are doing everything they can do to shut down it all together, they've even managed to shut down funding to scientists researching gen4 and other nuclear technologies...
They actually think it's feasible to go 100% solar+wind, which is absurd in a country like Sweden.
Bart Bols Honestly, it's just misinformation. The perception is that nuclear is incredibly dangerous while it quite simply isn't
Don't attribute to malice what can be adequately explained by stupidity.
Also it's probably just a more likely platform to get them voted in.
The first Green Party was founded in Germany by an ex nazi who basically wanted to fuck with the world economy, knowing that the worst effected would be the poor (and mostly black) parts of the world. Thus everything that provided a good, scarcity free future was opposed.
This being the first Green Party, his book and ideology spread rapidly, and he basically became the patron saint of green, permanently ruining what would otherwise have been an ok idea.
I thing there is a new movement called "blue" that aims to become what the greens could have been, but I haven't looked into it much.
Humanity’s rejection of Nuclear power was a massive mistake, and the environment has payed dearly for it as we continue to rely on fossil fuels for our electricity
Really glad you brought up thorium plants, more people need to know about them. They've had great results with them in India, and with better design structures that they use it's almost impossible to have a "Nuclear Meltdown."
Timothy Richter we need to end coal
They wont cuz money is better then life right???
Thanks for info
Also, India is Great....
Ye a thorium reactor would be very very very hard to have a nuclear meltdown due to thorium needing plutonium to work and the reactor would be able to instantly separate the thorium from the plutonium stopping any meltdowns to happen
Do you have more info about the Indian reactors?
"This will probably offend no-one and lead to very civil discussions."
Nice.
"but nuclear contra"
Yes, thorium is the future, up until fusion reactors.
I agree but until the powers that be get out of the way and allow someone to build one its not going to happen ,it needs a high profile person to get on board ,Elon Musk Richard Branson or someone like that.
I know ITER is currently building a prototype for a nuclear fusion reactor to proof that it is possible and from what I could see it looks rather promising.
True It is a long road till we get fusion reactors, but if we developed thorium reactors which would be viable for a while, this would give us a lot of time to engineer fusion reactors and they would be pretty great.
Fusion will be commercially ready in the year 2500. The first generation of breeder waste will be pretty much inert by them :P
Maybe.
Also of note...Solar panels are not permanent. High quality panels need to be replaced every 25 years, and cheap panels (like the ones most of us get from China) need to be replaced ever 10 years or so. And since we don't have a good waste/recycling program, all those heavy metals wind up in African landfills where they leech into local water tables and endanger the indigenous populations.
Wind ain't so good, either. In addition to killing thousands of birds every year (many of which are endangered species), the rare earths used in their magnet-brush systems are highly toxic to refine, and it's mainly done in China (Bao-tao, specifically) where it creates vast lakes of radioactive toxic sludge.
But hey! Those feel-good Clean Energy pictures, right?
It's not about which energy source is good, it's about which one is better, or more specifically, less bad.
Let me balance the argument: Fossil fuels, while cheaper and great for developing countries, produce large amounts of CO2 that gets pumped into the air. The side effects are clearly visible in China... literally. On some days the smog is so bad it's not recommended to go outside without a mask (before covid, now everyone should always have a mask). Not to mention the fact that it's a greenhouse gas, and climate change is no small thing.
@@autumn4442 Not to mention the nasty stuff that fossil fuel plants put out OTHER than CO2.
Personally I'd love to see more development and implementation of Thorium, as well as treatment of Uranium waste to be re-burned and then stored for 300 years, rather than 300,000.
@@somedandy7694 in india there are plans for creatng thorium reactors but we'll see how it goes
Yea actually the production and disposal of solar panels makes them as harmful to the environment as coal or natural gas.
@@sadslavboy Not really. While the production and disposal of them ARE harmful, it comes nowhere near how bad fossil fuels are for the environment.

Excellent pro-argument. Those that are against nuclear ALWAYS forget that the alternative to nuclear (coal & gas) is way much worse. It will be decades before renewables are a viable alternative to nuclear, coal, and gas.

THE WORLD NEEDS ENERGY
*Deal with it*
Jacob Hunter Have you heard Drake's new album? He's got a whole song about his energy. Drake is the solution to the energy crisis.
TC Coltharp The only reason renewables are not viable is because corporations and companies are not investing in it (that was similar to the case in the explainer video). Nuclear may reduce emissions but renewables will stop them.
Dylan Storer Actually fortunes are being put into renewable and progress is being made, it just isnt good enough yet.
Dylan Storer renewables are not viable because the costs of the plants are astronomical, while the gain of it is minimal (compared to other sources).
many governments invest heavily into renewable energy sources and subsidise them, in order to artificially make them lucrative, especially in central europe.
Thorium for president!
Till fusion shows up at least.
Ok
Absolute traitor talk to all of humanity..
Both sides on the argument agree on two things:
1) Nuclear energy will have to be out of use eventually.
2) The current method of nuclear energy harvesting is poor.
I say we switch to Thorium until we can move on to forms of renewable energy, as fast as possible.
hell yes have thorium reactors until renewable energy is viable for everybody
+Manuel Campins thorium will outcompete & throw renewable energy out of the market, after thorium & generation 4 nuclear we will go to nuclear fusion
+Manuel Campins Nobody said that nuclear energy will be out of use. The theoretical productivity of nuclear energy is such, that in the far future it will be the only viable form of energy. Instead of using a minor percent of what our sun is spewing out, we will create our own stars. And we will prosper.
+Manuel Campins Renewables are a great supplemental power source, however they are not grid viable and never will be. Thorioum will be used for thousands of years, until it runs out, and in a few hundred years fusion will be making power as well. I actually see Thorium being used primarily to make liquid fuel alternatives from gasoline out of seawater, ans fusion providing the brunt of electricity production.
The best place to throw money at renewable energy is in bio fuel pellet mill operations and methane biodigestion.
But the world just demands too much for renewables. In order for humannity to get past our own planet we need nuclear.
+Manuel Campins Nope. As a pro-nuclear supporter, nuclear energy should never be replaced. After all, how will we colonize deep space? Solar panels won't work at the edges of our solar system. Fear of nuclear power should not hold us back. It is and should be a permanent solution.

David Blakeman "Fried by the sun"
Really bad sunburn!
The vast majority of solar panels are made with silicon which is not harmful. We are fossil fuel dependent because billionaires are making money off it and will go far to keep it that way,
Nuclear energy is the way to go. The worst nuclear accident was caused by stupid humans and is very much preventable.
And even then, it has required disabling automatic safety interlocks.
Nuclear is NOT THE WAY TO GO FREE ENERGY FOR EVERYONE!!! Nikola Tesla DID NOT LIVE AND DIE FOR NO REASON. WAKE UP!!!!

I honestly don't think we have any choice not to use nuclear energy. It is the only form of energy that can replace fossil fuels completely.
Ieuan Hunt Why?
Renewable energy can as well. You're just making a blanket statement.
Renewable energy is expensive and at the moment requires a lot of empty space to operate.

Of course, but it seems rather irrational to switch to energy sources with so lower energy density...
***** No, because renewable energy cost a LOT, and as it turns out not so ecological after all. A solar panel doesn't polute does it ? Yes, it does: during the making, and it's not even that durable.

What I mean is you can shut down coal power plant and replace it with a nuclear power plant. You can't do that with renewables. The tide only moves twice a day, wind turbines only work when it is windy, solar panels only work during the day.
Nuclear power works all the time.

@Ater Deng The disasters are atomic nuclear bombs, not nuclear reactor. The only bad thing with nuclear energy is the wastes.
And scientists are even trying to find a solution to solve this problem, just needs deepest researches.
So... What ?
@Ater Deng Yeeeeeeee right of couuuurse yeeeeee tottaly right
tbh before watching this video I thought that we should totally avoid nuclear energy at all costs, but that Thorium model sounds amazing
Yes. Thorium sounds great, but if we can get Cold Fusion up and running, then we have a good chance of reviving nuclear energy!
+Maximilian Baade Cold Fusion is purely hypothetical at this time. However, other fusion generators are currently being developed.
+Tavo Hapson Thorium sounds awesome, but the liquid salt reactors have huge problems with corrosion. Turns out 450°C flouride melts are not the nicest stuff to put into steel reactors...
Btw: There are also standing wave breeding reactor designs (for uranium fuel) that could utilize natural uranium/spent fuel rods. I'd rather bet on that.
+Maximilian Baade You see, your reference to cold fusion makes me wonder whether you are a sarcastic douche who knows exactly how unlikely cold fusion is and is saying that Thorium reactors are equally unlikely, or if you are uninformed and enthusiastic....
+Doping1234 China has a 10 year program to have an energy producing liquid thorium salt reactor, they announced and started it in 2014... so by 2024 would be the estimated time of having a working LFTR reactor.
ITER first plasma reaction test is scheduled for 2027.
Germany just this month December 2015, tested and successfully ran a low energy plasma in their twisty tokamak reactor.
I think fusion reactors would be available about 2040 to 2050.
I think a LFTR model bridge would be good until then to avoid adding CO2 into the atmosphere, and LFTR is actually cheaper in the midterm than using fossil fuel energy; thorium is very abundant and the amount of energy per unit of thorium as it mentioned in the video is huge, like tokamak fusion, you get so much energy per unit of fuel it makes making other energy distribution methods via electrolysis to make H2 or a synthetic hydorcarbon chain using water and CO2 from the atmosphere cheaper than using gasoline or diesel.
Only draw back LFTR vs Fusion Deuterium lithium-tritium breeding blankets is LFTR does have some waste mostly cesium, which has a high cross section (it absorbs neutrons more than it will split and release energy) so you can introduce too much cesium waste back into a thorium reactor, you'll likely end up with some storage of radioactive cesium. Fusion deuterium has no waste products at all, the tritium is incredibly small amounts and it's alpha decay is very weak doesn't break skin, 9 hours after an immediate shut down, you can go into the plasma chamber and do repairs without any worries of radiation. Neither can "meltdown" and neither can be used for nuclear weaponry.
I have NEVER heared of the positive arguments of nuclear energy. We often just hear the negative aspects of it. Thank you very much for showing (again) how important it is to see both sides of the coin.
After seeing this video, I apologize for my ranting comment on the previous nuclear video. This pointed out pretty much everything right about nuclear that my comment outlined. My appreciation for Kurzgesagt has been raised even more. Thank you for being so thorough in your work! Glad to be a Patron!
Sad they didn’t develop Thorium in the 60s because it was rhe cold war and couldn’t provide weapons...
Well... Mutual Assured Destruction probably did prevent the Cold War from going Hot.
Those who develop nuclear plants either already have a nuclear bomb, or don’t want to have any (like Germany, because it would be impossible for their international image). A country that makes plants already has the industry and R and D to make nuclear bombs, so the risk of weaponisation is irrelevant really.
not sad it was stupid. Sigh....
Much like the Space Race without the Cold War it's doubtful that they would have been serious interest in nuclear power to begin with.

_How about we do it [shutting down nuclear power plants in favor of coal]..._
*Anyway!*
I don't know if I'm feeling what they felt in the 1950s, but nuclear energy seems to be the way to go (For now anyway) Every time I consider a world powered by Thorium, the world seems greener and better. Cars and vehicles powered by electricity generated by the non-CO2 producing Thorium reactors makes it seem like global warming would no longer be a concern. But this might be me looking at it through rose tinted glasses.
+Mr.chang cooler even without thorium, nuclear fission can last us thousands of years, and as space flight gets easier and cheaper, we may be able to mine uranium from other moons and planets, not only to power us on earth, but any colonies on mars, or titan or the like. nuclear has a world of possibilities, its a shame the world was so quick to turn on it.
+superskiier50 current uranium reactors only have an efficiency of 0.5%, while thorium boasts an efficiency rating of up to 54%. not only that - but uranium is about as common on earth as gold or platinum, while thorium is as abundant as lead or neodymium. huge, huge, huge gains.
the only problem with electric vehicles, however, is that they require efficient and long-lasting batteries - which we do not really have just yet. until then, they will be unable to really compete with gasoline or diesel vehicles on a large scale.
+Kevin Keel You mixed up 2 different percentages there. That 54% is a thermodynamic efficiency while the 0.5% is fuel utilization.
You can burn 100% of uranium with fast spectrum neutrons and you can burn 100% of thorium using thermal or fast neutrons. They can both use the same 54% efficient turbine if they can reach the correct temperature. There is also a lot more accessible uranium in the oceans (than the crust) which would be economical to extract if we could burn it 200 times better.
+Kevin Keel you know theres electric cars with over 250 miles per charge right? thats more than enough......

That would also require abundant power production as well. Making synthetic fuels is far less efficient than using electric cars and requires more overhead.

Unbiased and fair, Like
I am the son of a nuclear physicist and while still having been relatively young (7 years old) when the accident in Tchernobyl happened, I still remember very well when my Dads beeper went off that evening (he was working for our governments radiation protection agency). Being in Europe and therefore close to where the wind blew the radiation, as well as getting first-line information from radiation measurements all over Europe I believe i was a bit "more involved" than the general public.
All the "fuzz" after the incident, over many years to come, made me grow up with a very negative mindset about nuclear power. After having had a discussion with my Dad about nuclear power about 10 years after it happened, he was nonetheless convinced that nuclear power was definitely the path to proceed forwards, as it is more efficient and better for the environment. Eventually I changed my mind and now I do agree with him, however we need to find a way to take the biggest risk - the "Human factor" - out of the equation to make it safe in the long term.
Gen 4 cannot have a meltdown. :)
Just saying, the future is here.
I'm such a fan! I love your art style and media references! I subscribed after just a couple weeks!
I am really happy that you mentioned Thorium reactors. They seem very promising especially security-wise since they operate using a liquid fuel opposed to solid uranium.
For anyone interested search for the term _LFTR (Liquid fluoride thorium reactor)_ - there are interesting documentaries on that topic.
Two comments, because I *love* your videos.
Annatala Wolf The Co2 thing is painful. Somehow this made it through multiple spell checking rounds. About neutrality and balance - we did strongly opinionated videos on purpose - the information density is as much as you can fit in about three and a half minutes - if you want to try it just for fun, one script has about 3200 characters (including blank ones) it is really impossible to get much more into detail while covering a lot of different topics. We did a lot of research and had an expert as an adviser. About the bias. From scanning the comments we see that people read into that, most of the time on the side that they are on. We have no overall contra bias on nuclear energy. Our team is split on this topic. The pro side was more involved with the pro video, the contra side more with the contra video. Both sides got to say their favorite arguments in "their" video. Overall we think this is a fair representation of both camps.
Knock it off you two, no civilized conversation/debates on UA-cam comments.
Annatala Wolf The first thing you learn in journalism 101 is, "Remain unbiased always". The second thing you learn is, "It is impossible to be completely unbiased. Everyone has opinions and ideas".
Kurz Gesagt
Neutrality doesn't mean arguing for a side that's wrong. It means stating the facts. After all, when you made your evolution video, you didn't also make a creationism-explained video. Being neutral doesn't mean arguing a side that is wrong. Nuclear is our best option.
***** I'm not sure it was a good idea to delegate only members who believed themselves to be in the supporting camp for a point of view to put forth the arguments for that point of view. I understand and appreciate what you're saying about an attempt at neutrality, though.
I have a psychology degree (prior to my work in the hard sciences) and it is not surprising that people tend to see a neutral argument as being oppositional to their personal point of view. Nonetheless, I am not by any means a strong supporter of nuclear power, and the direction of this video still seems to undermine the arguments it is making. First, examples with the script like those I illustrated in the original message. Second, the direction of the video such as the labeling of containment of toxic waste a "bad idea" when the depicted form of containment has never actually been implemented (due to cost rather than lack of feasibility or risk, high-level nuclear waste remains uncontained). But third and perhaps most of all, the notable omission of two of the most important aspects of nuclear power: economic feasibility in the long-term (once infrastructure is in place), and its existing footprint (many European countries are already highly dependent upon nuclear energy to meet their energy needs).
Anyway, all of that bitching aside: you make nice videos. Please keep making more of them. :)
Kurzgesagt has provided us with a thesis and an antithesis !! It really remarkable
I know im 2 years late, but the antithesis is actually a joke video, thus why its a shit video with incorrect event dates and biased topics
World, "We need to move away from FF to protect our environment."
China, "LOL."
Sten Schmidt 1. Sources? 2. By "Leader," I assume you mean "Nation with the fastest annual FF reduction." Which I can agree with. Unfortunately, this is because they are the number one consumer of fossil fuels by a landslide. So having the largest marginal reduction isn't really that impressive. At least in my opinion. However, I will give China credit for at least trying to create a reduction. Anything helps.
China is actually the country investing the most in renewable energy. Granted, they're also the country feeling the most need to, as they are suffering the worst effects of fossil fuels.
USA (TrumP): let's use coal again and basically unsign everything that was good for the earth
"ROR"*
The absurd ideology of the western powers:
1. Start Industrial Revolution
2. Harness the power from FF
3. Release a ton of greenhouse gases
4. China begins to use FF as a late starter
5. Blame China for releasing all of the greenhouse gases
Okay, I've watched both vides and I have to say Nuclear comes out stronger. The two of the three criticisms of Nuclear outlined in the 'Nuclear energy is terrible!', accidents and waste, are effectively addressed in this video. Namely that Nuclear saves lives relative to Fossil Fuels and that CO2 waste is far worse than Nuclear waste.
The Nuclear weapons thing is the only argument not really addressed (aside from the Thorium bit). But we are not in the Cold War anymore. Full-scale conflicts between states are very rare nowadays (see Kurz Gesagts 'Is War Over?' video) and conflicts bad enough to devolve into nuclear war are difficult to imagine. Besides, at this point any country determined enough to develop nuclear weapons (at the cost of losing face internationally), already can. A fear of nuclear weapons alone is not a good enough reason to block nuclear power.
You may want to check, how much CO2 is released in the production of the fuel. That could change your mind. And don't get me wrong, I don't argue for coal/gas, I'm just arguing against nuclear energy in its current state.
sxfreak I know Nuclear plants produce CO2 at some point in their life cycles, but so do renewables like hydroelectric.
According to the IPCC, emissions over the life cycle of Nuclear Energy are comparable to those of renewables. After doing some additional research, it's very difficult to find an agreed upon comparison of CO2 emissions from different energy sources. However, even the most anti-nuclear sources seem to acknowledge that Nuclear is better than Fossil Fuels.
Sxfreak
Solar panel.manufacturing emits more co2
sxfreak The total life cycle carbon emissions of nuclear, including fuel fabrication and uranium mining ect, is similar to that of wind

It's even not just the CO2, coal emits shit like mercury and even uranium. It's an incredibly dirty source of energy.
A teacher was having everyone write questions bout society problems and I wrote one about nuclear power plants switching to Thorium reactors. He did not know what that was so I said I would make a presentation.
+SamThe RandomG1rl Teachers- people who get paid to be dumber than their students.
That's a bit harsh. I would consider a school teacher to just be a normal layman in most areas outside their specialization (and this one seems to have been specialized on society?). After all, their job is not to be up-to-date on cutting-edge knowledge, they're paid to teach the very basics to new generations.
And just because this one teacher didn't happen to watch random "bits of knowledge" videos online for entertainment doesn't mean he's "paid to be dumb".
i know its been a few years since the video release but, i just wanted to say that the reason we aren't using thorium reactors is because of what the video says, its really hard to make nuclear bombs and stuff with it (including the waste, its very safe) and apparently that's bad and the only reason we use uranium reactors is because of one simple google search, its backed by the government because it produces plutonium from the waste, which is handy for bombs.
In both videos, you portray nuclear waste as a liquid held in simple barrels. Neither of these attributes are true; spent nuclear fuel is a solid, and it's stored in large, well-shielded casks.
Er.
The argument you just made would be equivalently applied as "guns and bombs use chemical energy, therefore we shouldn't use chemical energy"
I'll put it this way: the use of nuclear energy makes nuclear weapons less likely.
How?
Uranium-235, in a country with nuclear energy, has an economic value of something like $36 million per gram - that is, the electricity that one gram of U-235 can produce in conventional reactors is worth $36 million. So to waste the 10kg of the stuff on a weapon requires significantly more motivation if a country has nuclear power than if not.
Now, if you want to talk wasteful, let's talk wind power. For the same amount of energy output, a wind turbine requires about twice as much concrete, steel and aluminum as does nuclear, and around 10 times as much land. It also requires us to use a significant amount of neodymium - a material we're already straining for, and on the order of 100 times as much as the same amount of nuclear.
Meanwhile, wind generation and demand rarely coincide. If you don't store the excess power, its wasted. If you do, you're wasting batteries on what could be load-following, and wasting about 20% of your energy as battery cycle losses.
o0
go do some real research, instead of repeating what your mom's friend heard from some fear mongering chain email
***** holy crap it's like you just ate up the fear mongering handbook. Uranium doesn't kill you nearly that quickly, in fact the alpha particles (the most dangerous) can be stopped with... nearly anything, because it reacts with nearly anything. A thin piece of paper or even a couple feet of air is enough to save your skin, and even then your skin is fine, it gets shed off (in most cases) before harmful effects can occur. IF you decided to eat it, then yeah, it would end very, very badly for you.
Beta particles are meh, and gamma rays are just high energy light. The farther they go, the less reactive they are with your cells. That doesnt mean walk up to a nuclear reactor though, keep in mind if the chances of a beta particle causing a DNA mutation are 1 in a trillion, there's already trillions of beta particles zipping around. good shielding has always been an issue (that is, other than super-thick walls of concrete or other dense or ionized materials. But will these kill you in 5 seconds? not unless you're standing inside the actual reactor. In fact there's videos on youtube of people handling pure uranium with their hands, and even using geiger counters. It's not nearly that bad.
Also they wont blow up randomly. It takes an intense amount of energy to start a nuclear explosion
"Uranium kills you in about 5 secs that your not wearing an hazard suit."
Well shit. Don't I feel all "Sixth Sense".
No, seriously, I've got a small rock of uranium ore sitting on my desk at work. I've handled it directly for more than 5 seconds at a time. I must have died in like 2010.
I figure you're talking about spent fuel; it _is_ extraordinarily dangerous (despite what Calvin DiBartolo says, there's enough gamma flux there to kill a man at a meter or so) - which is why it's kept in big thick concrete casks.
"Also Uranium is rare and very costly"
It's about $100/kg. In a conventional reactor, 1 kg of uranium will produce about 750 MWh of electricity - about 15 American households' worth for a year. In terms of economic value, that's about $75,000 worth of wall-juice. Most of the cost of nuclear electricity comes from financing, regulation, operation and maintenance of the reactor. The fuel accounts for 0.01 cents / kWh of the cost of electricity.
By comparison, 1 kg of coal - the "cheapest" form of electricity costs about $0.10, and can produce about 4 kWh of energy - about $0.40 worth.
So compared to its economic value, uranium's not in any sense "expensive"; it's easily the best cheapest fuel we have available.
"won't last forever"
No, probably not. However, it'll outlast fossil fuels by a couple orders of magnitude at least, no matter how hard we exploit it.
At present, uranium extraction isn't particularly aggressive, and in sum, we've only got easy access to about 6 billion kg of the stuff. At our current consumption rate, this will last us about 1,360 years.
If we were to replace 100% of our energy consumption - including non-electric stuff - with nuclear electricity made in conventional reactors without reprocessing, it'll last about 35 years.
Reprocessing is the act of taking spent fuel, taking out the fission ash that limits its ability to burn, and putting the fuel back into the reactor. This is reasonably energy intensive, but would only account for a fraction of a percent of the fuel's embodied energy in a single cycle. Doing would enable us to reuse the same fuel about 8 times - an aggregate burnup of around 60% turning the 35 years for full deployment into 280.
But that's not the _best_ route. There are reactors on the near horizon that achieve 98% burnup - converting 35 years to ~460. Additionally, they can consume thorium - which has a prevalence in normal crust about 4x that of uranium - 1,840 years.
Of course, we can't assume our energy needs will remain static. Various sources have predictions for the world's energy growth needs - but if the entire planet gets to American levels of prosperity and energy consumption, we can expect the world's output to triple. Assuming that this tripling happens every hundred years or so (which is an extraordinarily generous assumption), that brings the 1,840 down again, to 265 years.
However, I stated above that the 6 billion kg is only what's _easy_ to get. If you double the price you're willing to pay to get uranium (to $200/kg), the availability of the stuff increases tenfold, according to current geological research. Taking into account growth, that still brings us to 475 years. Double it again, and it goes up by 10 again - 684 years, assuming centennial tripling.
Another doubling of price - to $800 / kg - and something changes. Seawater extraction of uranium becomes economic, and the availability of uranium increases by a factor of about a million - 2,000 years worth, again, assuming we triple global energy consumption centennially.
Incidentally, at 2,000 years in this scenario, we'll be consuming at a rate of 52 zettawatts - high enough that I not only had to _look up_ the appropriate SI prefix, but thought it a bit high, and looked up global insolation - 52 ZW is 520,000 times the 100 PW or so we recieve from the sun.
That's not going to happen, but it does give an absurd lower limit on the total possible available fission fuel. Realistic estimates say that the human race should top out at around 50 TW, all said and done, which should burn up all of our fission fuel over the course of 4 billion years.
I didn't even bother going into the efficiency increase that would come from switching from high-pressure, low-temperature reactors to low-pressure, high-temperature. The increase from 33% efficiency to 40% should push us that last billion years until the sun burns out - assuming we haven't worked out fusion and left the planet in the meantime.
"lets talk if it blows up its taking the whole dam area with it"
There has been exactly one fission-driven reactor failure in the history of nuclear power - Chernobyl - and there's a simple reactor property that caused it (though there were several things that exacerbated it, most pointedly, the lack of any secondary containment whatsoever).
RBMK reactors have a positive temperature coefficient of reactivity - the hotter they get, the more power they produce, the hotter they get. It's surprising to me that more haven't gone up.
LWRs have a negative coefficient; if they get to hot, reactivity falls off until the reactor falls back into normal operating range. However, they have a different problem: pressure.
Now, I trust good engineers - but not even good engineers trust pressure, regardless of how well-contained it is. Pressure vessels are, as such, notoriously overengineered. RPVs and secondary containment domes are no exception here, and as a result are both the main drivers of cost and danger from a conventional reactor.
Again, those reactors on the near horizon are, almost without exception, of the atmospehric pressure core variety. No danger from a core that very much doesn't want to be where it is. No giant cost driver from an overengineered containment.
I don't expect you to get on-board for future tech, of course - no one got anywhere betting on fusion in 10 years for the last 50. But with at least 8 different projects approaching this at small variants of the same angle (molten salts), and another 15 approaching it from another (metal-cooled), mass commercialization of an atmospheric pressure reactor of one flavor or another is pretty certain within the next 5 years or so (Russia's already selling a 600 MW metal-cooled, but they're reserving their big sales effort for the BN-800 they're working on).
"lets talk if it blows up its taking the whole dam area with it"
Can't believe I missed this initially.
LWRs can't blow up, at least not in the nuclear sense. Fukushima's explosions were based on hydrogen, evolved from the overheated fuel cladding interacting with the coolant water - a chemical explosion, and one that damaged the reactors.
Meanwhile, people _could_ move back to Fukushima right now; the I-131 (the only demonstrable health concern from the reactors) had all decayed away by the three month point.
What's left - Cesium isotopes - have not been shown to increase cancer odds or radiation exposures significantly. They don't concentrate anywhere in the body, and their biological half-life - 100 days - is significantly shorter than the radiological half-life of the isotopes in question. Meanwhile, radioactivity measured in the area is presently within the range of natural radiation throughout the world.
So even using the loosest interpretations of "blowing up" and "taking the whole damn area with it", LWRs are demonstrably incapable of this, even in the worst situation.
Still, I'd like to see us get low-pressure reactors to the point where they're readily deployable.
With low-pressure reactors, we would never have to worry about the safety of nuclear energy again, as the main mechanisms by which a core is moved into its surrounding environment would be _gone_. Nuclear accidents would be strictly industrial accidents - with their harm strictly limited to on-site damages, instead of the weak radioactive contamination that causes so much media apoplexy today.

@@ionicman2908 yeah. Both videos are posted on april 1
It’s not pro anything. They have a video talking about why nuclear energy is bad too.
that tardis with plutonium barrels at 0:29
i know right
There are tardis in every kurgesagt video lol
"Thorium reactor [...] and it's hard to make a nuclear weapon out of this"
But... My nukes!
damn those sensible idiots!
We must innovate in 100%recyclable nuclear technology in future.
Unfortunately, Uranium is NOT a renewable resource. It only comes as a byproduct of really big stars that go supernova. Luckily, we've already got a very large amount that already exists here on Earth and is enough to fuel humanity for a VERY long time.
We must innovate 100% non-stinky poo in future.
1:10 oh shit. It's THAT Turry
Could you guys do an episode on Thorium Energy(Liquid Fluoride Thorium Reactor(LFTR)). It's a new and exciting up and coming source of energy and I believe if you do just a little bit of research you will love it.
I love mentioning the first point to those people who disagree with nuclear power. It seems counter intuitive if all you know is what they show on the news, but looking at perception of risk for diffuse vs point source pollution is a very interesting thing.
People it's NOT April's fools. This is not a joke.
Becasue of all the people that still think that nuclear energy is bad is why I believe that this decisions should be made by scientists that now what they’re doing and not politicians
You are sadly mislead my friend free energy already exists invented by Nikola Tesla!!! Wake up!!! Demand free energy from your government!!!
Casden Simonson I’m so confused...
Are you any type of conspiracy theorist??
@@evyiennetla9416 ah yes free energy, very real
Video was made 1st of april
@@YellowDire so what
This three-parter left me more uncertain about the topic but more informed. How does that happen
That's the nature of being informed about something. Nuance exists.
SCIENCE BITCH.
My stance on the subject is, if we go full nuclear then there will be more research done in making it cleaner and even safer. Then there is also the Eventuality of fusion which will replace everything. And he is the other thing, what if more money in nuclear research causes the fusion research to speed up? Then wouldn't that be the best decision to make?
The way it should be. Only uninformed people are ever truly certain.
Yes, I believe what your saying is correct the problem is nobody cares about this issue, as everyone is more interested in the stupid arguments being brought up by the current presidential candidates. Our Earth is bleeding, and if we don't do something about China in the next 5 years it will be too late
The 1 tonne Thorium to 200 tonnes Uranium claim is misleading. In a theoretical Thorium LSR, 1 tonne is equivalent to around 200 tonnes of Uranium in a Light Water Reactor, however LWRs are the least efficient Uranium reactors. You can achieve similar performance using Uranium breeder reactors.
what’s the waste produced by the uranium breeder things like tho.
@@jib6689 breeder reactors "breed" more fuel than they consume. There are several designs that fit that description. That means they can continue to burn nuclear fuel that would be considered way too depleted for other reactors, or even make fuel for new reactors. They generate virtually no transuranic waste (the "bad" waste), as it's just more fuel. Their waste consists of non-fissile fission byproducts that go inert in a relatively short time (think 100 years as opposed to thousands of years)
Thanks a lot for the portuguese translations, guys! Awesome!
ive seen both sides of the argument and think that overall it would be better to use nuclear energy than to stop but we need to make some major improvements such as improving efficiency (incorperating betavoltaic cells into the reactor walls,actually using plutonium,using thorium,insulation to trap heat with a heat valve to release extra heat,pyroelectric cells,reflectors to reflect radiation back into the reaction chamber,reuse of irradiated water[water containing tritium and deturium] for fusion experiments,ect) we also need to improve safety systems to avoid nuclear disasters and convince investors it is less risky.
It's my life goal to figure out how to harness fusion on earth!
+x Lunar Tip: don't try to buy nuclear material on the internet. Found out the hard way.
+MegaKwijibo thanks man xD
+MegaKwijibo Now tell the whole story, I want hear!
+MegaKwijibo Yeah, I wanna hear about it too xD
Lunar, my uncle works at general atomic a in San Diego and they already have done nuclear fusion in reactor model just saying. Though you could attempt to make it usable and efficient enough to be commercially used.
Just out of curiosity what materials we can use that are still available to build a Thorium Reactor and how much will they cost for each unit?
There's no one answer for that question.
+kokofan50 no I meant whenever we decided to use nuclear fusion which will probably take decades
Possibly ten million or more?
The only issue I've been able to find with thorium is the lack of readily available super alloys in large quantities such as cupernicle
They are build a new modern reactor in Korea for about 3 billion and it was estimated it would be even cheaper to build a Thorium Reactor, whereas the same capacity would cost about 15 billion if wind was used...
This video appeared to focus more on "Why nuclear energy is better than what we use now" and the other one was on "Why nuclear energy sucks". This is like the self-driving car debate. And pseudo-quoting GCP Grey on this, "Self-driving cars don't need to be perfect, they just need to be better than us..." This relates to this topic in that nuclear power does not need to be perfect, it just needs to be better than all the other options we have available, and it appears to be the case at the moment, especially in the case of the theorized thorium reactor.
ZweiSpeedruns While we're theorizing, what about the theorized artificial photosynthesis?
All the technology for thorium reactors exist, it's just no one is willing to pay the startup cost. Artificial photosynthesis would indeed be better (more efficient than solar panels), but we're talking about what is feasible in the present. Not to forget photosynthesis itself is basically re-arrangement of atoms in molecules to form sugar, and this process itself is very similar to nuclear fusion, with the difference that energy is in the byproduct rather than the process itself.
The only reason uranium instead of thorium is used is that initial research into nuclear power was for warfare, and uranium was the best for doing so, so we learned how to work with it and not thorium. Thorium reactors ARE possible to build at this very moment.
I hate debating with people, so I will leave with this closing argument and go back to being like Switzerland to the best of my ability
ZweiSpeedruns
Are we talking MSR's here? if so there are some really vexing plant lifetime corrosion issues to be worked out
MSR's?
I guess we're not talking about them if I have no idea what they are :/
+ZweiSpeedruns MSR is Molten Salt Reactors (a thorium burning reactor is an MSR). And yes what @Stephen Nielsen says is the biggest focus of research how to concur corrosion so that the reactors last longer than the theorized 15-20 years with current technology.
It would financially not be feasible if a thorium reactor only runs for 15-20 years. 30 or 40 years is the benchmark
Thank you for the interesting pieces of information! Without them, I would not have been able to complete my school project.
Nuclear power, hydro, wind and solar is what we should switch to as a planet... And be less waist full
There really is no valid "other side of the argument". The points here clearly debunk or outweigh the otherside's claims. You can't call nuclear energy dangerous when the other forms destroy the planet, toxify the environment, kill people, don't meet energy demands fast enough and are fought over with war. Just because nations can male weapons with them, doesn't mean they will or will use them. Besides the lesser developed countries can stick to coal or gas. Developed ones, trusted and civilized, use most of the current energy anyhow and already have nuclear weapon capabilities or stockpiles (or closely allied with such).
The fact we only need 4000 reactors to solve our energy demands is actually impeccably a good thing. If the waste gets to much.... use that energy to send rockets with it to space, store it on the moon or launch it at the sun and say good by. There is plenty of space on Earth for storage of i as well as the potential for reuse of it.
Why would anyone ever want to pursue a good idea, though? Way more economic to keep pumping shit into our atmosphere?
One mistake, and entirety of human population is destroyed in a matter of weeks. One madman, one terrorist, one sleepy, tored, overworked person, we are doomed. I am fully aware of all the benefits. But the risk is too high.
@@MarkoFTW Have you been watching The Simpsons too much? The reactors can endure a plane crash, and emergency cooling reserve is deployed by gravity.
@@HalNordmann that makes it sound like they were made by aperture laboratories

why do you think this?
1:11 “Turry gets great at handwriting”
Seeing how those 2 videos have the same amount of views brings smile!
ONLY MINECRAFT VETERAN'S CAN FIND OUT WHY THE BEACON HAS A BLACK RAY AT 1:44
Russia ruined it for the rest of us. This really is the best and cleanest energy if we don't cheap out and make it safe.
How can solar energy kill someone?
Those calculations usually include the sourcing of the raw materials as well as the processing and installation. So it probably includes deaths in mines, factories, and in installation.
You'd be surprised how many people fall of their roofs.
Vampires in the workforce
Mostly people thinking they can install the panel themselves and falling off the roof.
If you have a serious injury from an accident and need to be rushed to the ER. But the hospital had to close down because it was a little cloudy
Came here after watching the How Many People Did Nuclear Energy Kill? Nuclear Death Toll video - the potential of investing in Nuclear tech is so beautiful, the Thorium reactor alone blows my mind.
