Fusion Energy: Hype or The Future? 

A couple of corrections: At 3:13 I said the processes the wrong way round. The FISSION part is only there to aid the FUSION part. And ICF is Inertial Confinement Fusion not Internal. Sorry about that.

my favorite part about generating electricity is that we're always just trying to find the most complicated and efficient way to boil water to turn a turbine.

"And yes, I finally made a video about fusion in this channel, ColdFusion" Another major milestone.

I strongly recommend everybody to take a look at the video that Improbable Matter made in response to the Real Engineering one about Helion. He has worked in the field and can explain all the challenges of fusion in great detail. What happened on december 5th was historic, in the sense that is the first time we extract more energy that we put in without using an A-bomb as a trigger (we cannot ignore that we had been building fusion reactors that work as insteded since the 50's, they are just single-use only). But if we write down a list of the engineering problems we still have to manage that we don't know how to solve, it's amazing how astronomically far we are from a comercial fusion reactor. I'm sorry guys, but apparently we are going to get out of this energy-poverty well with fission, and the sooner we start the better...

"The power of the sun in the palm of my hands" Never thought that would become a reality.

"Before everyone celebrates, there's a lot to be done" is practically the motto of human scientific endeavour. 👍

While I'm optimistic that we have made big steps with fusion, things like Helion aren't all they're cracked up to be. There's a good response video by Improbable Matter which strongly suggests Helion are really over-selling themselves for investment and are banking on a less efficient reaction with big question marks over scalability and danger.

I visited JET (Joint European Torus) in '96 at a physics tour in England among other things. We were shown the torus (Magnetic Confinement Fusion) and the facility. They told us that they had to phone the power-stations in advance in the area when an experiment was due or else the entire area (a small city and two or three suburbs) went without power. JET used that much power! And it's rather small in comparison to what it uses; kind of a small living room or an apartment with a single room. Edit: I forgot to say, that the power-stations was able to turn up to full power and THEN the experiment could take place without any bother.

Great video Dagogo as always, thank you! btw, you mixed up the fusion/fission relationship - the initial fission reaction powers the fusion reaction which is the majority of the explosive power.

If I'm not mistaken, the main source of Tritium is Fission Reactors. So, ironically, in order to scale up Fusion we may need to scale up the number of Fission Reactors, with all of the problems associated with that. Unless we can find a different isotope to use in the fusion we're going to need to have nuclear power in a lot more places. Apart from the dangers and mess they make, they are also very expensive, slow and complex to build.

If you ignore the fact that they actually put more energy in than they got out of it, they got more energy out of it than they put into it.

Fusion is the energy of the future… and always will be

This sounds like it will take a century to become commercially viable.

I love these videos and the music - Im amazed how talented Cold Fusion is!

ColdFusion has finally made a video on Fusion. And I remember the days when the channel was called "ColdFustion". Makes me feel a bit old. 😁

Pretty sure they did end up putting more energy into it, id suggest you look further into it

Dagogo: "For proof of it, just look up at the sky in the daytime" Viewer: "AHHHHH my eyes!!!" Lesson learned? Don't look at the sun!

4:10 Essentially fusion is just two nuclei falling for each other then giving off that spark. Ah yes it's chemistry at peak performance...

Channel name checks out! Thanks for all the great videos.

4:13 “The electrons say sayounara” with the most chill voice 😂

Hello Dagogo! Love from A Briton and Nigerian living in Germany. We love your channel and all you do. Proud of you keep it up.

I love this kind of optimistic better future videos, we're on the edge of new era breakthrough and I can't wait to see how this pans out.

Thank you for the provided information to us the mass and for keeping us updated.

Great episode as always,keep up the GREAT work

The power of the sun, in the palm of my hand!

The energy needed to power the lasers was 300 MegaJoules. They gained only 1 MegaJoule from the whole process. So we are minus 299 MJ. We have a long way of optimization in front of us.

Thank you Dagogo for the most SOBER video yet about this topic. Well done! ❤

The simulation of the ignition laser is amazing, and getting all those split beams to converge at a point is mind blowing. I know the work is hard, days are long, and it’s not all fun and games, but the people working there must get amazing satisfaction.

There is a lie already in the very 1st minute. They didn't get more energy out than what they put in. They forgot to mention the energy used for running the whole fusion😂😂

Also did you see "Improbable Matter" on the Helion company?! VERY interesting and grounded stuff on this channel on the whole fusion game!!

Loved that you mentioned the fusion part at the end

Really glad you covered what Helion is doing in this video. Assuming what they have is real (and I hope it is) I'm hopeful the way they are doing direct energy capture with electromagnets is the winner here. Cheers and please keep up the amazing work.

I've been learning Nuclear Physics the past week. The day humanity cracks fusion... I hope I live to see it.

Great breakdown of a complex system to generate energy. Yes this has take long to get here, but advances in science and engineering will make it a reality. Thanks again Dagogo for a great show. Love you subject matter that seems you never run out of steam. 😂😂

Yessss I was wondering if you were going to mention that finally did a fusion video, coldfusion!

I've always been interested in fusion energy, but many of the articles or journals I found on the subject were geared towards scientists and were hard to follow at times. Thank you for making this video, I learned a lot.

I think the main explosion in an H bomb actually comes from hydrogen fusion, and the fission is only used as a trigger for that reaction(like the lasers...), supposedly there's not that much radiation from an H bomb, just insane explosive power. Really hope to see a viable fusion reactor in my lifetime, what a game changer!

I'm glad you're being cautious to make sure people know that the practicality for this is still decades away. But I think the step taken here is more than just "a large step". Most people thought it was fantasy before (not even sci-fi) because of how long it was taking to take this one large step. Now that this has been confirmed to work on this scale, so much more support for it will begin pouring back in. More *human excitement* was produced from this reaction than was put in. (Sure, Scientists knew it was possible. But scientists aren't in charge of directing funding.)

Good job on a clear and unbiased presentation Dogogo! Bravo 👏🏼

Another great video from your channel as always and keep up the good work Dagogo 🎉🎉🎉

I sorely missed these optimistic videos. Thank you

I seem to recall reading an article right after Dec 5th, and one of the scientists was quoted as saying something like, "our breakthrough moment came when we realized we don't have to pump energy into the reaction once it starts. The reaction itself will generate the temperatures needed. We just have to get it started." or something like that. I could be mis-remembering that, though.

Finally understood, a little bit complex topic of CHEMISTRY - PHYSICS. Thank you ColdFusion!😊

Dang, I love your videos. I enjoyed the fact that you mentioned the project in Southern France the ITER.

Thanks for the vid, I was just wondering today how the steam deck is doing. Indeed it seems that allowing other developers to add enhancements seems to add more value and utility to these things. Good to hear it isn’t walled off.

I don't think anyone said creating the conditions of a star on planet earth would be impossible. I believe what they said was extracting energy from it for use as a power source was impossible, and still is. It would be great, but I'm not holding my breath.

Thanks Dagogo, great to see different approaches to achieving a fusion reaction Healthy competition is a great driver to the progress of a goal. This would transform the worlds power production.

Excellent summary of the three most promising fusion tech. Thanks

It's a step, it's a milestone, but not yet a breakthrough. I'm so excited to see this happen in my lifetime! I think a big step forward would be finding a way to not need such high purity precursors. Ultrapure water in of itself is a nightmare to purify and store (ask anyone in the semiconductor fabrication industry). When dealing with heavy water for fusion, I can only imagine the headache associated with ultrapure heavy water. I believe that not needing ultrapure grade heavy water I think is a possible next milestone, and possibly not needing heavy water could be another one, though I have less faith in that idea, since deuterium is the most thermodynamically efficient precursor as far as I know. DISCLAIMER: my background is materials science, chemical engineering, electrochemistry, and molecular physics. I am not a nuclear chemist or physicist. My only exposure to nuclear fusion work is reading the scientific papers associated with the work out of my own interest.

ColdFusion -- documenting the future, 20mins at a time

Listen your videos are awesome and so unbiased keep em coming man

I think you should do a video about what great things this breakthrough will actually create like what thing that were impossible before fusion is possible if fusion is done

The only channel which remained my favourite since childhood🥰

I’m almost in tears watching this because you’ve done this so well. I learn something new about our world every time you upload. I really appreciate all the work you put in to educating millions of us about our world! Thank you a million times over!

I absolutely love your ending pun about doing a video on fusion by your channel Coldfusion!

Love that last part "And yes, I've finally done a video on fusion on the channel Cold Fusion" - as always great content and music!

Fusion will be great when it happens. I had a chance to work briefly on ITER, and I can say that it is an experimental facility that MIGHT overcome many of the limitations of prior tokamak reactors. In any case, commercial fusion power generation is still a couple decades off. In the meantime, we should be pushing for molten chloride fast reactors (MCFR). These are fission reactors, BUT without many of the concerns that plague traditional fission reactors in current operation in the US, and with many of the advantages of fusion. MCFR does not use water to slow neutrons down or to cool the reaction. Instead the reaction happens with fast neutrons, which can much more completely use up the fuel, resulting in only short half-life waste products, and can use a wider variety of materials as fuel, including natural/depleted uranium and thorium, as well as much of the existing spent fuel waste stockpile (which still contains a lot of fissile material that simply could not be utilized by the slow neutron reactors). Since the system doesn't use water for primary cooling, there is no high pressure steam to contain, thus reactor vessels can be made much more cheaply. And the reaction is self-limiting. As the temperature increases out of normal operating margin, the liquid reactants expand, slowing down the reaction. Key advantages: Can't melt down Can't have steam explosion or release of radioactive steam Self regulating Broad range of fuels Little new waste and using up existing waste TerraPower and Elysium Industries are both working on pilot plants to prove commercial viability.

Now that you have done an episode on fusion, you better make one on cold!

This was fascinating, thank you, Dagogo!

Thank you for another wonderful wonderful program again I hope to see you in Scandinavia, giving some lectures and playing some music in the Buffalo thank God for having you around us fitting us with wonderful insights

Not necessarily, if ITER with its 23,000 tons produced 1 Gw-h, assuming that half of its mass is Neodymium (reactors are basically giant magnets) and that it does not use more exotic elements. With the current reserves we will have about 10 Tw-h as a viable maximum.

My favourite part about the fusion experiment is that they didn’t count the energy the lasers used.

I'm so ready for Cold Fusion episode about Cold fusion

great way to ended fusion on Coldfusion! :)

ColdFusion talks about Fusion

This Channel has come a long way since the days of ColdFudsion, now he's finally covering Fusion technology!

ColdFusion talking about Fusion. Phenomenal video !!!

It's astounding to think how far humanity has come in such a short period. Best wishes to those working on a cleaner, brighter future!

Let's hope that fusion energy will be the energy of all the masses in the future.

Why are even science/tech channels that should know better spouting this B.S. The overall power input of the whole system was about 400 MJ. They produced about 3 MJ. They did not produce more energy than what was put into the overall system. This garbage that it produced more is from the fact that the lasers only delivered about 2MJ to the fuel. Power delivered to the fuel: 2 / 400 = 0.5% of input. Power produced: 3 / 400 = 0.75% of input. Yes this is an important milestone but telling people more energy was produced that used is just flat out wrong and people aren't going to look into or even understand the distinction when this line is being pushed by those they consider experts.

Good highlight. Thanks for sharing it ✌️

Wonderful explanation such a wonderful energy source

"they produced more energy than they put in" Only had to make a billion dollar machine to do it.

I'm hoping that AI will help with fusion as well as other technologies. I am hopefull

ColdFusion's mini-documentary on fusion energy... I've been waiting for this 🤤

Great broadcast

I thought you'd also talk about the Wendelstein-Stellerator experiment which just cracked a 8minute sustained plasma milestone. But these guys are in Germany, usually not so boastful.

Fusion energy may be the far future of energy, but right now it's all hype

Exciting times ahead !!

For reference as to ignition. Iter is designed to have 1,000% ignition, DEMO is expected to reach 2,000%, and what is considered commercial viable will be 10,000%.

Success is not built on success. It's built on failure, It's built on fraustration. it's built on fear that you have to overcome. I pray that anyone who reads this will be successful in life

You will get to grift on this for another 4-5 decades. Well done sir, great video.

Great video. Very informative.

This is your favourite cold Fusion

Despite the economic downturn, I'm so happy 😊I have been earning $ 60,000 returns from my $9,000 investment every 15days.

Finally.. cold fusion doing a video on cold fusion!

Great video, thanks!

Nicely explained, man!

My favorite part of the episode was the last nod to Fusion! 🔥

You have the best voice! It’s so good

very good presentation mate...

Thanks a lot for making this video.

luv your work

Whenever you see, even momentarily, passion, it's all wide open.

This is huge. It will take time but it will revolutionize everything!

ColdFusion finally making a video about Fusion 😅

I love the name "ignition". It really is like igniting matter, just not in the usual combustion sense.

Dam this Fusion video was ice Cold 🥶

I'm watching your channel for the last ten years and I never get tired of! Can you make a video about procedural content generation, not for games, but for programming cells and another high complex simulations? A video like that will be mindblowing for me and a lot of others. (I'm not that kind of person, who asks for videos xD) Thanks!

Is that a new sound track i hear at the end? Can’t wait to hear more!
