Is Nuclear Fusion The Answer To Clean Energy?
Nuclear power has a controversial history, but many energy experts say it has a major role to play in our energy future. Some in the industry are working to make standard fission power safer and cheaper. Others are pursuing the holy grail of energy - nuclear fusion, the process that powers the sun and the stars. If we figure out how to harness that power here on earth, it would be a huge game-changer.

Is Nuclear Fusion The Answer To Clean Energy?
17:44 “public opinion on nuclear fission remains split” Badum tss That’s a good one 👍
The nuclear power plant operator was greeted when he begun his shift, "May the weak force be with you!" For those who didn't get the joke, I quote Wikipedia. "In particle physics, the weak interaction, which is also often called the weak force or weak nuclear force, is the mechanism of interaction between subatomic particles that is responsible for the radioactive decay of atoms"
Rofl xD, good one.

Nuclear engineering is amazing. I had the privledge of knowing Tom Andrews, Senior Instant Response Coordinator for the Nuclear Regulatory Commission in the Dallas area. Amazing guy.

Sounds like he was a great guy.

Being for the environment and against nuclear is the most hypocritical way one could think. Also, the data processing abilities and AI algorithms have sped the race to positive production fusion.
Being for the environment and against nuclear is basically for the destruction of the modern world.
They don’t understand that the amount of pollution from nuclear energy is astronomically less than coal, and we still rely mainly on coal for energy
STOP fission now!!!! STOP gas now!!!!! Let's use candles and horses to save the planet!!!!!!
yet amazingly almost no one actually think there's an enormous nuclear reaction inside the Earth that has been burning more than 4 billion years, I doubt that even the most destructive volcano eruption that has the power to wipe the entire human race could make people realize how much energy in it
I am actually tempted to agree with this. I remember supporting environmental policies over ten years ago, but it astounded me how much a large portion of the environmentalist movement hates nuclear as much if not more than fossil fuels. I understand the risks with catastrophic meltdowns, and I also understand how nuclear waste is a very bad problem, but both of these risks are grossly outweighed by all of the pollution and greenhouse effects that fossil fuels have created. Nuclear also stands to become much more refined and cleaner with more research: Fossil fuels are pretty much at a dead end when it comes to research, apart from just increasing fuel efficiency.
Opposing fission because of exceedingly rare disasters is akin to opposing aviation due to airliner crashes. Yes when things go bad they go really bad....but it's still much safer to fly than it is to drive. The same goes for nuclear fission. It's safer not only directly for us, but for the planet.
@just another human 'Farnsworth' never built a nuclear reactor you nitwit, fusion, fission or otherwise.
@just another human kzhead.info/sun/ra2kZdeBmIt_hHk/bejne.html A Farnsworth Fusor is an early design for a nuclear fusion reactor. The design is ultimately impractical for fusion power generation, because the amount of power generated with such a design has never come close to even equaling the amount of power that must be put in to sustain the reaction.

That's why most private ventures are successful, atleast in an economic sense, than most public ventures.

17:44 _"public opinion on nuclear fission remains split"_ then we must *unite* our efforts for nuclear fusion
"Nuclear fission was discovered in late 1938" (Germany). Nuclear fission was first theorized by Tadayoshi (Japan, 1934)
Isaac Newton didn't "discover" gravity he simply formulated a way of explaining it.
Nah but Hahn could explained it, which Tayadoshi wasn't able to(He couldn't proof it).
Nuclear is absolutely the best way to be "green." Glad to see some attention being shined on the subject...this is a debate we seriously need to have. Safe, clean and plentiful, why would we NOT be producing more Nuclear plants, that is the question.
Because if push came to shove, Nuclear could go disastrously wrong. How do you actually handle nuclear waste
@@vasu6494 Nuclear waste can be recycled, but US refuse to do that.

@@andrerichardson the history of major great innovation was with rejection, ridiculed, and laughter..
I totally agree. This is definitely a mentality issue. We have to encourage governments to contribute actively in fusion energy projects no matter how long it takes. If finally a breakthrough is achieved, it's going to be the biggest solution to our energy crises. We have to make the public aware of the benefits of fusion energy to our planet and our future generation by educating them. This is the only way a mentality change can occur. At the moment the vast majority are ignorant to the benefits and knowledge of fusion energy.
its a funding mainly same problem with space advancement stalled due to funding. But something like this is going to take 200 years to develop if not more its a synthetic sun in a cage
Fast forward to today when multiple times already fusion has achieved a net positive energy production

Besides hydropower, nuclear energy is the only renewable energy that is available 24/7 and 365 days a year. Confusing fusion with fission might be the greatest limitation to the success of nuclear power.
don't forget geothermal, which is great where it is available.
@@jsmariani4180 Agreed. :-)
Hydropower can affect local tectonic and cause e.g. localized earthquakes. Wind power plants can affect weather conditions - e.g. prevent humid air from reaching inland. Neither source of energy is without cons.
I think electricity in general is amazing in our everyday lives. It’s easy to forget that and take it for granted. As for side effects, I suppose weighing pros and cons is the best we can do.
@@NetZeroTech Yes, that is true. Considering impact on environment, on all stages (including production of required components of power plant), I think nuclear energy is slightly better, causing less environmental impact.
I just want to thank all the people working so hard for the world on impossibly difficult issues.
"A number of high profile accidents.." You mean 3....in the last 70 years. And really only 2.
It's at least three. Anyway, even two would be too much. Take a look at Japan. Fukushima nuclear disaster happened in 2011, but they are still struggling to contain it. The total cost of the disaster will be more than the construction costs of all of Japan's nuclear reactors combined, according to current estimates at least 450 billion dollars. One disaster made Japan's nuclear energy extremely expensive. Because of the Chernobyl disaster large part of the forests and agricultural lands of Ukraine and Belarus are unusable. Again, intolerably expensive and damaging. There are other good reasons to give up nuclear power, but even these are enough. Nuclear power (fission based) is slowly dying anyway. Building of new reactors has practically stopped in developed countries, and by far the largest builder, China, has recently stripped down most of it's ambitious nuclear program, and is building renewables instead. In 2019 China made more than half of the global investments in renewable energy. I'd say the competition is already over. The future is renewable. Fusion might have been good, but has already missed it's time window (I originally wrote "fission might have been good..." by accident - sorry about that).
@@ademeionademo3703 the fact that renewables are most invested in isn't an argument that they are the best. Problem with renewables is that you need to rely on something that is unreliable. Nuclear power plants are hugely effective and incredibly green for their reliable output (even with kWh/co2 they go toe to toe with solar and wind and usually come out better). In my country (Czech Republic, around 10M people) there are only two nuclear power plants which are back bone of our power production still to this day (built in 80s). One thing you can also reconsider is that IF (and that is a big if) nuclear accident happen, it will probably ruin a lot of agricultural land. If you build solar panel field, you will ruin that field 100%. Because another great problem is kWh/km^2. I understand your worries about nuclear energy. From my point of view renewables have not convinced me that they are solutions to the problems they claimed to be
Ademeion Ademo Nuclear is the only way, nothing else can scale to our needs. We start with fission and then move to fusion once we figure out how to do that, fusion is certainly the only option looking hundreds of years into the future.
@@TheShadowBannedBandit You are quite correct about nuclear, except we don't need fusion. 1/ We won't get hundreds of years into the future without nuclear. 2/ Nuclear fusion is not nearly as free from residual radioactivity as in 1961 I thought it was. Helium is not radioactive, but the superfast neutrons that get nearly all of the energy have the capacity to transform any other nuclei into something radioactive. 3/ I have read that the brilliant Andrei Sakharov, one of the inventors of the Tokamak, pointed out that fission of massive nuclei produces more energy _per reaction_ than fusion. It's also IMHO easier to capture for civilian purposes. Given that one atom each of tritium and deuterium has a mass of 5, and that thorium, uranium and up have masses over 230, the energy per unit mass comes out better for fusion, but when you consider the apparatus, that's probably misleading.
albert rogers Well, considering the big ball of fire in the sky runs on fusion not fission... somewhere your logic is flawed.
Nuclear is the best way. We have to break through this mental barrier that society hold on nuclear...it's absolutely safe, even safer then other energy production. Cost will go down by itself as the technology advances. We saw this with our phones and laptops. We just have to start funding it now to maybe have a future.
Nuclear is promising but I think we also need to be honest about its shortcomings. As the video pointed out the economics aren't great even after decades of experience with nuclear tech. Its also not going to solve climate change all by itself, since we can't build nuclear power plants in every country due to a) proliferation risks (just think Iran) and b) lack of energy infrastructure to operate a massive nuclear power plant (think 3rd world countries). The 5-10 year built time is also an issue. We need to reduce CO2 emissions right now so relying on nuclear alone will cost to much time to get it done and there is a limit on how many reactors a country can build at the same time, since there just aren't that many nuclear engineers around. Just pointing this out since some people seem to think that nuclear is the silver bullet that solves all problems when it isn't. Its just an important piece of the solution.

Dan ketika reaktor masuk dalam talian, kata Laberge 10:53 ia akan menjadikan kos kuasa General Fusion bersaing dengan arang batu 10:56 dan pembaharuan seperti angin dan solar. 10:59 Pada kadar 5 sen per kilowatt jam, sebenarnya cukup kompetitif. 11:01 Seperti lebih murah daripada banyak perkara lain. 11:04 Tetapi ia tidak lebih murah daripada gas asli. 11:07 Laberge berharap ia akhirnya akan menjadi lebih murah, kemungkinan jika 11:11 A.S. memutuskan untuk melaksanakan cukai karbon. 11:14 Pasaran tenaga di planet ini adalah satu trilion setahun. 11:16 Oleh itu, jika kita mengambil sebahagian besar dari itu, kita akan mendapat sebahagian besar daripada 11:20 trilion dolar setahun. Tetapi sebilangan pakar industri percaya bahawa swasta 11:24 syarikat seperti General Fusion terlalu optimis dengan syarikat mereka 11:27 garis masa. Dalam 10 tahun terakhir, terdapat banyak industri kecil 11:32 datang untuk mengatakan bahawa kita dapat mencapai perpaduan dalam lima tahun, sepuluh tahun. 11:36 Saya tidak mempercayainya. 11:38 Saya rasa mereka memandang rendah dan tidak memandang penuh cabaran a 11:43 reaktor pelakuran. Peleburan nuklear sukar. 11:47 Tidak ada kumpulan atau syarikat penyelidikan yang dapat mencapai apa yang disebut 11:50 titik pulang modal, di mana tenaga yang dibebaskan dari tindak balas pelakuran berada 11:54 lebih besar daripada tenaga yang diperlukan untuk memanaskan plasma yang digunakan dalam tindak balas. 11:58 Ini sebenarnya bukan teknologi tenaga. 12:04 Ini adalah penyelidikan asas. 12:07 Penyelidikan asas mempunyai nilai. 12:09 Tetapi untuk menjualnya sebagai teknologi yang akan menyelesaikan keperluan tenaga kita di 12:14 20 hingga 30 tahun akan datang adalah menipu. 12:16 Kami tidak begitu dekat. 12:18 Tetapi penyelidikan asas adalah roti dan mentega Lawrence Livermore National 12:21 Makmal. Ini telah meneliti fusion sejak penubuhannya pada tahun 1950-an. 12:27 Pada tahun 2009, makmal membuka Kemudahan Pencucuhan Nasional dengan tujuan untuk 12:30 mencapai titik pulang modal dan akhirnya memicu tindak balas pelakuran. 12:34 Dan dengan menyala kita bermaksud bahawa ia dapat memelihara diri. 12:37 Ia dapat menyebar ke seluruh bahan bakar yang terdapat dalam letupan. 12:42 Lawrence Livermore mengejar perpaduan inersia. 12:46 Iaitu, mengurung plasma pada tekanan yang sangat tinggi untuk jangka masa yang pendek 12:49 jumlah masa, menggunakan laser tenaga tinggi untuk melakukannya. 12:53 Kami berdiri dalam apa yang kami sebut sebagai Target Bay kami, melihat sasaran kami 12:58 ruang. Ruang sasaran adalah bola besar sekitar 30 kaki di seberang, dan di 13:04 di tengah-tengah bola itu, kami meletakkan sasaran yang sangat kecil mengenai ukuran 13:09 hujung jari saya, dan kami memancarkan sasaran itu dengan seratus sembilan puluh 13:15 dua laser paling bertenaga di dunia. 13:18 Penyelidik di Kemudahan Pencucuhan Nasional dan makmal nasional lain mempunyai 13:21 akses ke kekuatan pengkomputeran yang sangat besar, yang membolehkan mereka berjalan kompleks 13:24 simulasi yang membantu mereka memahami keadaan sebenar yang diperlukan 13:27 mencapai pencucuhan. Oleh itu berdasarkan simulasi terbaik kami, mereka mengatakan bahawa a 13:31 kemudahan skala ini cukup besar untuk mewujudkan reaksi pelarian ini, jika 13:37 semuanya berfungsi dengan ideal. 13:39 Tetapi jelas, menjadikan semuanya berfungsi dengan sempurna di dunia nyata adalah 13:42 jauh lebih sukar daripada yang kelihatan di skrin.

hahahah true that
Or plans for it.
did not watch the video. but, nuclear fusion hasnt been done yet. If it does work, it will be a great source of energy. Until then, stick to nuclear fission, which is actually a great replacement for oil!
@@gags730 For the US we only use oil in Hawaii (there are some plants in reserve for emergencies though mostly in the eastern US). The reason we got in the first oil crisis in the 1970's was that we had moved a huge amount of power production to oil. This greatly increased the consumption of oil and made us highly reliant on the Middle East. These mistakes were made by Johnson and Nixon especially and to lesser a degree Kennedy. The crisis is worse than most people realize. It caused a rush on US gold reserves and has lead to the inflation from that time to today. We moved away from oil after that mostly building coal power plants and some nuclear, but with fracking, natural gas became very plentiful and cheap in the US and most new plants became natural gas. There are two kinds of natural gas plants: simple cycle and combined cycle. Combined cycle is much more efficient. Simple cycle is cheaper to build and the old oil plants that were not demolished were converted into these inefficient natural gas plants. Nuclear became hard after 3 mile island. But this was due to lies put forth by the anti-nukes (who were actually bankrolled initially by oil tycoons because oil was being used for power generation at the time). They said tens to hundreds of thousands of people would die prematurely from cancer as a result of the radiation cloud release. That of course did not happen. Lots of studies...no increase. We have mechanisms in our cells that repair DNA provided the damage rate is slow. The media ate up the lies and continue to spout them because fearmongering brings in viewers which sells advertising. They said in this piece that long term exposure to low level radiation creates new worries...hogwash! We are designed to live in a radioactive environment and always have. It is called background radiation. Stick a Geiger counter next to a banana it will go bonkers. Also the background radiation levels have fallen off dramatically since they stopped above ground nuclear testing. Fukushima is a drop in the bucket compared to that previous level. In fact, it did not even stop the falling levels due to half life reduction of background radiation from the 1950's and 1960's. Not one person died due to radiation in Fukushima, but the news never says: "Big news nobody died" The guy mentioned that nuclear cost the least amount of lives per year on average. That number is 90 lives (mostly industrial in nature not radiation) per trillionkWhr (including the disasters). Sounds terrible doesn't it? Coal is over 100,000 lives! Oil is 36,000 lives. Even biomass is 24,000 lives. Natural gas is 4,000 lives. Even solar is 440 lives. And the US number for nuclear is 0.1 lives. We use oil in the US obviously but it is used for transportation. All other uses are peanuts.
@Usze 'Taham that is not strictly true we had electric cars before we had petrol and if we had not gone the oil route bettered would have advanced singifincalt and we would have used coal I'm jot saying coal is good I'm simply saying oil was not the reason why technology went forward it was simply one option to fuel that push forward there was and still is many others

I appreciate all the videos you guys thanks
I think getting usable work directly from the fusion reactor is just as important as the reactor itself. As they mentioned, they're going to use the fusion reaction (just like fission now) to heat water to steam to spin turbines. We're harnessing the power of a star, to turn it [basically] into a windmill. We need a more efficient way for the reactor to directly generate electricity.
Turning heat into electricity is always inefficient. There are solid state electrical devices called Thermoelectric generators, that generate electricity straight from temperature differences. This is probably the most high-tech way to generate electricity directly from a heat source. That means one side has to be heated while the other side is cooled...to create the temperature differential. (Most likely, water would be used to cool the cold side...so back to square one😅🤣) Anyway, efficiency is determined by the temperature difference and how well the hot side and cold side is insulated.

why? Just because steam turbines were invented a while ago doesn't mean you should throw them away. Do you still use wood, fire, hammers nails, spades and indoor plumbing. They aren't new.
@@michaeldavison9808 yes but we use those because there cheap strong and hold up well with time. But thats luck. we still use those because they've always been amazing at there job but energy is different. Its harder and expensive and when we are literally using the power of the stars for a spinning rod with wings that carries barely any energy compared to what we could get. Well can you see the problem, all the effort all that power for a spinny wheel to waste most of it. Its not only inefficient but wasteful and optimization is key in generating electricity. Even those good ole materials we still use may eventually be replaced. Heck in space travel alot if not most are and nuclear fusion could be key to space stations or moon colonys.

Just go Thorium, 20 Tons of Thorium produce almost the equivalent of 200 tons of Uranium or 10 000 000 tons of coal
problem is you have to build new reactors.
@@lukasanzengruber5993 i've heard that it should be as simple as retrofitting old powerplants to suit moltensalt reactor
Not to mention it’s nearly impossible to create weapons with, cannot have a meltdown in a reactor, and is more common than uranium
problem is it's rare and cannot be used to supply even 2 percent of the world
The main obstacle is that weapons grade Uranium is needed to start the process. That would give more nations an excuse to produce or procure weapons grade Uranium. Most rouge states already possess weapons grad Uranium...so I think this is a dumb reason to hold back Thorium reactors.

9:50 “preheated up to a few million degrees” I’m sorry, what??? I want to know more about that! Sounds really interesting to learn how it’s preheated to those temperatures amongst other things!
It depends a lot on the type of fusion reactor, but often it's done by basically microwaving the gas in a way if I recall correctly (definitely not a nuclear scientist, do not take any of my word as fact). The reason it works is because the gas is kept away from the walls by electromagnets, and thus there isn't really anything to give heat off to. Second reason is because the amount of gas is tiny, just a few grams, if even that, so relatively little energy is necessary to get it to those temperatures (Still needs an incredible amount of energy however). Linus Tech Tips has an entire video about this specific reactor design, as they visited it.
Yo are heating only two hydrogen atoms.even at few million degrees,the heat i unlikely to be dangerous
As SlayerOfTheBad said, there are many approaches. But the typical tokamak reactor design uses lasers to heat a very small space, confined by an intense electromagnetic field (so it doesn't directly contact the other materials in the reactor). This is also why it is so difficult to get more energy out than in, because both those lasers and strong electromagnetic fields take lots of energy. But, as with most things, these things tend to get more optimized and efficient over time.
David pretty sure a tokamak doesnt use lasers just regular old microwaves Lasers though are used in a different design where they shoot lasers from all sides and that way compressing and heating a tiny peelt containing hydrogen But im no nuclear scientist

This was excellent. Thank you CNBC. Of the scientists featured, I would have like to have heard their opinion on thorium reactors. But I appreciate how all of them agreed that it's not simply one solution that should be looked at, and innovation should be promoted in all the areas discussed.
if you put metallic particulaie into a fluid that is driven by the steam of the fusion core .. you can skip the turbine as it runs through magnetic coilsz .. also you are only turbining once .. you can have sequential turbine chambersz .. as long as pressure is ocntrolled to flow
The fusion reaction at 6:07 is not complete: a neutron is missing. It is D + T --> He + n. This is quite a significant mistake, as the neutron is used to heat up the walls of the vessel surrounding the plasma, and thus eventually driving a turbine (generating electricity). The energy of the Helium nucleus is used to further heat the plasma, trying to sustain the fusion reaction.
He + He --> S +H + Am + O + U + Na

The public in general isn't even strongly against Nuclear energy are they (I'm talking about conventional Nuclear energy using current, proven technology)? Isn't the fact that Nuclear is really expensive (and takes a really long time to start getting a return on your investment) the biggest reason why Nuclear isn't more popular? Once you do get to the point where your Nuclear plant has paid for itself, you're getting an enormous amount of power relative to the operating costs (including the costs of storing nuclear waste). And that's with current Nuclear technology. It could end up getting a lot better, and we should invest in trying to figure out how.
Cannot wait for fusion. I heard it's only 20 years away from being commercially feasable for 50 years now.

"public opinion on nuclear fission remains split" 17:43 i see what you did there
this.
20:24 Nuclear Power isn't a zero sum game. Fission is the solution for the short term, near future, up to 2050 (perhaps even 2100) but Fusion is the long term solution for 2100+ and beyond and won't just meet our energy needs here on Earth but will also allow humanity to begin colonizing the solar system. Fission harnesses the power of splitting the atom while Fusion harnessing the power of fusing it, which is what powers the sun, which is the reason for all life on Earth. We should be investing in BOTH!
Precisely. 💯💯
Exactly
Wholeheartedly agree, development and improvement of fission plants as well as further research and investment into eventual fusion power are both imperitive
Assuming we will find a way to NOT fry our planet before then with too much CO2 being dumped in to the atmosphere and heating up the permafrost CO2 storage bank.

Unexpectedly well done. Thank you CNBC!
I'm here after the announcement.
Same, revisiting the sentiment 2 yrs ago to now.
There was no coverage here on Thorium which is cheaper and considerably less hazardous.
Thorium is a possible fuel for fast breeder reactors, but currently it is more hype than anything else. There is enough already mined uranium out there, even enriched one. Just disassemble those terrible nuclear weapons and use them as fuel. And use the light water reactor waste as fuel too. When we get low on these resources, then we could start mining Thorium. But until then so much time has passed, that there is the possibility that fusion is also an option. Currently existing technology are Gen III and Gen III+ reactors. These are the reactor types that are inherently secure (don't need active cooling, won't self destruct when let alone) and can be built right now. There are even designs for Gen IV reactors like the GE Hitachi Prism. Unfortunately we live in a time where people are scared to death by one the safest forms of energy production ( www.nextbigfuture.com/2011/03/deaths-per-twh-by-energy-source.html ).
In what ways are thorium cheaper? The logistics alone will be expensive, not to mention the ongoing trade war with all thorium rich countries.

Why not talk about thorium fission reactors? There's a lot of potential to be used there and it would fit beautifully to the theme. Great documentary tho.
Because we need "normal" nuclear reactors to hide the true cost of building nuclear bombs (which is why, for example, in the US, nuclear weapon grade material creation comes under the Department of Energy, rather than being part of the defence budget) so there's a lot of money and power behind giving people a false impression of thorium not actually having any benefits, including some very official reports that can easily convince gullible reporters (who think they are journalists) who are left with the impression that it's just some quackery that people on the internet believe.
@@annoloki you know that in normal nuclear reactors low enriched uranium is used, while nuclear weapons need highly enriched uranium. Also this would only explain the reason why it's not used in the USA, while most countries don't even have nukes anymore.

The threat to the Earth and its species, is the promotion and use of "Energy Based Technologies," releasing huge amounts of Energy directly into the Environment.
I like the idea of fusion but I also like that we are looking at all kinds of ideas. We are keeping our options open.
Sorry to have to tell you this, but nuclear fusion is NOT like the solar fusion process. The sun takes four protons and with inordinately high densities and temperatures (1000 times that of the photosphere) in a remarkably long time makes a helium nucleus. The Bikini bomb fused together a tritium and a deuterium nucleus. That's two protons and three neutrons, and it makes a helium nucleus and a fiendishly high powered neutron. The problem is that the nuclear strong force needs neutrons to make it work. The other options --we have three or even four versions of the nuclear fission option quite well proven. But the biggest or "most successful" of the popularly defined "renewable energy" quite clearly are an expensive environmental blunder or abomination.
