Flexing
Flexing is not good for the containment
No, but some guy proved that we could use that to our advantage. If you don’t use the magnetic constrictors to compensate for the heat from the fusion expanding the vessel, you can have it enter fusion and leave fusion several times a second. Wrap the thing in copper wire coils, and you have now got your vessel in a state of flux, and producing enough power to blackout your local grid, and get lots of fines from the feds in less than 5 seconds of runtime. He obviously didn’t continue working on that particular method of generating power with a Tokomak
Can you link to something so I can read more about this please?
Rumor is next they are trying for 11.6858˙3 hours
A headline without calling it an “Artificial Sun”?!
The power of the sun in the palm of my hand.
@Toribor @notsoshaihulud with great power comes great responsibility
Don’t worry, it will stabilize
The amusing thing is that the sun is actually quite a shit fusion reactor. It’s power per unit volume is tiny. It just makes it up in sheer volume. A solar level fusion reactor would be almost completely useless to us. Instead we need to go far beyond the sun’s output to just be viable.
It’s like describing one of the mega mining dumper trucks as an “artificial mule”.
I think this energy density math really depends on whether only the core or the whole surface area is taken into consideration.
Even the core only has an output of 200-300W/m^3.
That’s about the energy output per volume of a 70 year old cyclist.
Arguably, the nearby sun scale fusion reactor has been fairly useful for us. Nowadays we can convert its output directly into electricity using solar cells
I never said it wasn’t useful, just a very low efficiency reactor. Then again, if it was better, it would burn out faster, which would be bad for life on earth.
Someone once told me a sun is just a fusion nuclear pile reactor and… Like… I guess.
They say “artificial sun” because that’s what it is though, there’s no fusion reactions here they’re just microwaving hydrogen to millions of degrees to study the kind of thing that would happen IF somebody runs a fusion reactor for 22 minutes.
Or a “star in a bottle”

But I’m le tired.
Well have a nap
The only reason to pursue fusion power research is so you can say this on a weekly basis. Any benefits to humanity are purely secondary.
How big are your hands???
This is freaking awesome. Only a few years ago it was exciting to see a fusion reaction last a fraction of a second.
Maybe if it runs longer, we all get to jump to a better timeline. 😅
Or the world blows up and it’s all over. I guess what I’m saying is, no downside, fire it up and let’s see what happens.
I’m sceptical. Even if somebody would present a working fusion reactor today, what would the timeline to replace everything based on fossil fuels even be? Build several thousand of expensive fusion reactors in every country of the world, even in geopolitical rivals like China, Russia or North Korea or war-torn third world countries? Replace every car with an electrical one? Replace home heating everywhere? Rebuild every ship and airplane worldwide?
Meanwhile in America we’re trying to make macdonalds cheaper by bundling an extra sandwich to go along with a value meal…
That’s called McFusion
And it only takes 22 seconds to consume.
And only 12 seconds to regret.
Which means you are still consuming the burger for 10 seconds fully regretting your decision.
110% commitment to the burger and the regret. USA! USA!
That’s way better than Taco Bell, where the regret sinks in when you consider going there.
Spoken like someone who’s never had a cheesy gordita crunch
And keeps you sated for another 22 seconds.
Then you want seconds.
America would blow up a fusion reacto, call it dangerous, elon musk has a lot of things to say about it and then it would be illegal worldwide. Have you guys heard about coal? We already fixed it, just burn coal.
Why don’t we use “shatters world record” like the pro-China articles where they did this for 16 minutes?
I know why.
I know!
Because the articles were written by different people and published in different magazines ya goober.
Nah.
It’s because of the Chinese propaganda machine.
Because that one was over double the length of the record before it and this one is closer to a 35% increase.
So it’s probably just a “slams”
‘Boinks’
whopping
Is it because of the Uyghurs?
Oh shit. Things are heating up in the fusion race.
IIRC it was expected because previous record from China was essentially a trial for this one. It all happens under ITER project so it’s not that much of a race.
Good shit. I’d rather this be a global cooperative effort rather than a jingoistic dick-waving contest.
Good. The only thing that was
quiteremotely good about the cold war was the competition.That’s not what this is, and even then, that competition wasn’t even good. You had two countries hoarding technological advancements for themselves, with everything having to be discovered twice.
This is a worldwide collaboration, where each assists the others, and it’s a much better way of making progress. See ITER.
I should’ve replaced ‘quite’ with a more clear ‘remotely’ but you’re absolutely correct
I didn’t see any mention of the output in the article. 22MW injected, but does anyone know if the reaction was actually generating a positive output?
No magnetic confinement fusion reactor in existence has ever generated a positive output. The current record belongs to JET, with a Q factor of 0.67. This record was set in 1997.
The biggest reason we haven’t had a record break for a long time is money. The most favourable reaction for fusion is generally a D-T (Deuterium-Tritium) reaction. However, Tritium is incredibly expensive. So, most reactors run the much cheaper D-D reaction, which generates lower output. This is okay because current research reactors are mostly doing research on specific components of an eventual commercial reactor, and are not aiming for highest possible power output.
The main purpose of WEST is to do research on diverter components for ITER. ITER itself is expected to reach Q ≥ 10, but won’t have any energy harvesting components. The goal is to add that to its successor, DEMO.
Inertial confinement fusion (using lasers) has produced higher records, but they generally exclude the energy used to produce the laser from the calculation. NIF has generated 3.15MJ of fusion output by delivering 2.05MJ of energy to it with a laser, nominally a Q = 1.54. however, creating the laser that delivered the power took about 300MJ.
I wasn’t aware of that distinction about the energy for the laser to generate the heat energy within the reaction not being factored into the Q value, very interesting, thank you! Would that energy for the laser still be required in a “stable reaction” continuously, or would it be something that would “trail off”?
Mr. Fusion now 1 step closer… 10 years late, but still!
Only ten more years, and we’ll have it!
…you said 10 more years 50 years ago
In just 10 more years, it’ll only be 40 more years!
I feel like the awesome back to future reference was missed completely.
So, some as graphene.
We’re using graphene! Almost entirely for it’s electrical properties true, but we’re using graphene doped batteries in consumer electronics currently. We also use fusion and ITER research for a whole lot more than just power generation - plasma dynamics, just one tiny subfield concerned with physics, has applications in everything from radio transmission beam forming techniques to satellite engines to magnetodynamic modeling to the EMI shielding on your vacuum cleaner.
I would like to subscribe for more graphene facts.
Has DOGE cut funding to ITER yet?
They sacked everybody. Now they are trying to get them back.

What about my racist and misogynist views I try to hide underneath my crazed and incompetent rantings about DEI? Is there room for someone like me?
You are now leading the department.

Didn’t read the article.
I have no clue wtf that technology is in detail but wouldn’t it be easy to have a longer reaction time by supplying enough energy? The news should not be how long the reaction lasted but how long it lasted selfreliant.
I read through it for the details.
It was net negative, requiring 2MW of power to maintain hydrogen plasma in a state analogous to fusion. The major achievement of this particular experiment was doing so without energies equivalent to a fusion reaction damaging the containing assembly.
It was purely a test/demonstration of the containment of fusion-like conditions.
Thanks for this TLDR. I’m too high to read actual things.
You need to be the right amount of high to properly understand fusion. Too far either way, and it doesn’t make sense.
Eh, fusion isn’t that complicated. You push things together and heat them up until they get even hotter on their own. That’s all that’s happening.
Wth is this comment?
A reasonable question.
Doesn’t sound that impressive when Wendelstein 7-X achieved 17 minutes of plasma in 2021.
Yes but 22 minutes is longer than 17 minutes
Think of it like a pizza oven
How well done is your pizza?
at temperatures that exceed the surface of the sun, there’s only one setting.
carbonized.
I can’t find a reference to that but China did 17 minutes in January this year. I think you’re confusing the announcement that they increased power by 17x while maintaining plasma.
This test was 20 minutes at a higher power setting without being incredibly destructive, that’s their milestone.
Agreed. Plus, when talking about that reactor you get to say “stellarator”, which is always fun.
This is cool but also remember the practicalities of Fusion make it not much better than nuclear:
Well nuclear is great, so even “not much better” would be great.
Yea one of the most interesting applications of fusion reactor research is the requirements in advancements for material science also benefits fission and even solar power generation, so the research bears fruit well and above the stated goals.
not to say its the greatest form of energy production ever, but, what are your gripes with nuclear these days anyway?
Well, really it’s the opposite, nuclear works already. So why not just build nuclear plants at 1/20 the cost? (and actually get some net positive energy)
Just saying…
this (specific project) isn’t about harvesting energy…
I understand that, it can’t be. Because fusion power generation hasn’t all been worked out yet. Unlike fission. That’s my point.
Also, once fusion does work, it will still be the most expensive way to generate energy man has ever devised, so there’s that too.
if I remember correctly, the output of a nuclear fission reactor can be used in a nuclear fusion reactor for a near-net zero loss in materials.
there’s like three different fusion reactors, so it’s likely one of the three that can do this, but still better than fossil fuels.
