PART 2 COMING SOON. Subscribe to see it: ru-vid.com?sub...
You’ve probably heard about nuclear fusion. Maybe you've heard recent news about the Livermore National Lab achieving a nuclear fusion breakthrough called "ignition" - meaning it produced more energy than it took to start the reaction. That's a huge deal! But it leaves other questions unanswered. I wanted to know more.
I started by asking the CEO of the nuclear fusion company Helion all my big questions: What is nuclear fusion, really? I know it happens on the sun, but how can we do it on earth? Are we doing it already? Then, I ask one last question: “I’ve heard about kids building fusion reactors in their moms’ garage… if fusion is so hard… what are THEY doing?” The answer sets off the most fun and ambitious Huge If True episode yet.
It turns out that you can actually BUILD a nuclear fusion device. So I team up with my friend Simone Giertz to try. When something goes wrong, it turns into an explainer on what’s really going on with the world’s most-hyped energy source.
Special thanks to Jessie, Ron and Joben at Helion for helping set up such an exciting shoot (and not giving up!). And thank you to Anna Bresnahan for helping shoot this episode!

Hey from the "misshapen metal bits" comment it sounds like it was your grid that was stolen? I built a fusor as my bachelor thesis at uni, and it was actually really easy to make prototype grids by hand with just stainless steel thread. Also from my experience you might benefit from more "spokes" on your grid.

At <a href="#" class="seekto" data-time="480">8:00</a> you refer to plasma as the disassociation of neutrons, protons, and electrons; however, (in this context) plasma is when the electrons are stripped from the nucleus (ionized) while the protons and neutrons remain bound to each other. I really enjoy your videos.

Great video Cleo! Thank you! Hello @HelionEnergy! Amazing tech. Godspeed! I'm curious what your take is on "climate change"? I suspect your probably "all-in" for obvious reasons. I ask bc despite it's near ubiquity these days, there appears to be a number of fundamental problems with the theory - esp. regarding carbon dioxide. The true answers to a few questions provide what anyone interested should know about CO2/Earth climate; what was the maximum CO2 level in the past? What is the "ideal" CO2 level for plants? What is the minimum CO2 level for plants? The current CO2 level in relation to the "true answers" to those questions tells everything one needs to know about what "the consensus" believes causes climate change. I encourage anyone interested to repeat the process. It's well worth it. Very enlightening! PS, I say "true answers to a few questions" bc the BS is everywhere! From all sides of the debate. The politics attached to this issue are pathetic and sad.

You always seem to manage to do it at times to explain the stuff that I'm thinking. Also it is great to see some underlying themes from the channel show through on different videos. You mentioned about the possibilities of having unlimited energy back in your clean energy video and the idea of reducing being mis-stated. I'm really looking forward to seeing the video in another 6 months and where things might lead.

@hari20001 Год назад

Congrats on the explanation, I loved this 101 on fusion. Thank you! Some of the issues that fusion systems are experiencing are how to overcome the great complexity of engineering challenges required to maintain a running fusion system. The systems being developed now only last for a very small blip of a second. I believe the more experiments we can do on a smaller scale (just as you did) the greater the ingenuity we can throw at the engineering difficulties of constructing a running fusion system and the faster we can achieve a sustainable outcome. Build small fusion kits in many Labs and Unis. Start playing with our ingenuity in problem-solving and experimenting faster. Unleash our most powerful weapon; a network of minds. Something we need to remember is that having the culture to play with ideas and methods is just as powerful in problem-solving as building a massive methodical laboratory process.

It's magical thinking though. The lack of time and resources we have makes it so that we can't just innovate and consume our way out. Fusion is actually a good example of something that's theoretically possible but may very well not be applicable or scalable to help much. It's why believers have to rely on erroneous fluffy notions like, 'we did other electricity stuff before.'

@@christianschmitt2409 it's just a very troublesome kind of optimism to have when facing such a crisis. The 'Don't Look Up' kind. I think the video that started it all is an even better example. Recall the example of adding insulation vs having abundant energy such that we won't even need to insulate. Insulation is a known, practical, lasting solution that effectively acts at least as well as adding extra energy to the equation. Why! Why undermine realistic and urgent mitigating requirements with mirage like hopes of abundant energy just over the horizon? The polished graphics presented by a skillful and seemingly well meaning person makes it all the more worrying.

@christianschmitt2409 Год назад

@@snizami that's a good point. Not adding insulation would be rather stupid. however, having abundant energy doesn't have to stop us from doing that. Energy will still not be free. and I totally see optimism being dangerous in this time. at any time, really.

I’m a high school STEM teacher. My chem class is doing nuclear chemistry right now, so I’m showing this to them. I may show it to my engineering class as well. I wish I could easily coordinate it with my algebra and geometry classes, but I’ll see most of them in chem. P.s. Whenever I face similar mispronunciation proliferations, I either switch to easier-to-say and/or smaller words: weaponization, militarization or arming all work pretty well. Complete ideas like “runaway military repurposing,” “exponential arms propagation,” and “uncontrolled weapons development,” all express proliferation people better than the obscure word itself (to most people).

I’m 100% behind continuing to research fusion reactors. Just not at the cost of slowing down our deployment of other tech like solar and wind. Like you said in the video, it feels like fusion has “almost been a thing” for a long time. There’s just too much risk that we never really manage to get it to work so we shouldn’t put all our eggs in that basket.

@odw32 Год назад

There's often some cynicism when people build "garage fusors", maybe in part because it's often linked to slightly overhyped articles about "genius teens". However -- too many people think that the goal of hobby engineering projects is to end up with an original invention, or a functional product. The important bit is the knowledge, the skills, the insights gained along the way! Projects like these inspire people to learn more about physics, visit makerspaces, work on their own projects, or even convince kids to get STEM degrees, which is a major win!

Because that's the only easy way to do Fusion, where you just make a very strong spherical electric field, and all the charged particles oscillate back and forth between the walls and collide with each other in the center. It just takes _WAY_ more energy to run it compared to the output, but it's a very good neutron source!

@CharlesBrown-xq5ug Год назад

Fusion is fascinating. Especially to those here. A very early idea I had was to put D&T in a hollow sphere and charge the sphere positive. Nuclei don't repel to the center as I may want because the cross section area of a samplng cone increases with the square of the distance while repulsion decreases with its square simultaniously so there is no preference for the center. After years I changed the goal. The new goal is to balance away the the nuclear repulsion separating the D&T nuclei Maybe a foam metallic glass sphere having very small precisely spherical hollows is the answer. The hollows may be defined by lithium microspheres. Spray the grounded sphere with Positively charged ions of interest. Aloha

In the 80's I heard that nuclear fusion was about 25 years away. I think that's still the case.

The proliferation issue is pretty complicated but that was a nice way to say why “controlled fusion” can’t be used to make a bomb. Fission has a tendency to produce smaller amounts of more energetic materials. This is because the freed subatomic particles need somewhere to go. A freed proton might join up with some heavy uranium. The product of hydrogen fusion is helium… a necessary element for chip manufacturing that is becoming scarce.

Wait, what? Why do you @Cleo Abram only have 243K subscribers.... I find your way in wich you are telling these video's fasinating... You are telling these stories in ways I have seen perhaps no other RU-vidr tell these stories... or well, perhaps Mark Rober is an exception... But in a different kind of way. Even though I love Simone, I think you should have WAAAYYYYYYY more subscribers!

Plasma physics PhD student here! I LOVED THIS VIDEO! Thank you for shedding light on fusion research :) Good Luck!

It's only a matter of time until we are able to stabilize fusion plasma for extended amounts of time, but sadly the prejudice against fission sets back the development of fuision despite fusion actually holding this huge potential for (compareatively) clean, sustainable and effecient energy! Also in regards to space travel!

Recently, a group of people was able to gain energy from fusion (a small amount, but still progress!)

I watched a video about Helion’s fusion project a few weeks ago and now this project is like the icing on the cake! To watch two smart people do something they haven’t done before!

at <a href="#" class="seekto" data-time="391">6:31</a> when the ceo talks about using fusion to perhaps add some more energy. That is an understatement. In thermonuclear bombs, fusion releases orders of magnitude more energy than the fission portion. The fission bomb serves the purpose to 'ignite' the uncontrolled fusion process - yes, it is that difficult. Fission bombs doesn't release enough energy to destroy the world,. The thermonuclear bombs, on the other hand, can alter geological feature - create large craters, take a chunk off of a mountain etc... If you look at the five permanent members of the UN security council: US, Russia, China, UK and France, they all have one thing in common - every country has thermonuclear weapons. btw, because the fusion process is so hard to initiate and maintain, the chance of nuclear meltdown event is much lower.
