The basic idea I had was that fusion plasma containment involves containing a turbulent, dynamical system, so it might require some kind of actual intelligence learning or co-evolving with the system.
I wondered if this might be the only way to achieve over-unity fusion outside gravitational confinement (stars, black hole accretion disks, etc.). This would mean there are two fusion mechanisms in nature: gravitational confinement and cognitive confinement. The latter can only be a product of a living system.
When a living system achieves this, its biosphere "ignites" and becomes something I termed a "biostar." Biostars could be potential SETI targets -- biospheres that have harnessed fusion and so emit anomalous amounts of optical and infrared radiation on their night side. This moment of ignition would be an event in a biosphere comparable to the evolution of photosynthesis-- a fundamental change in the energetic dynamics of life.
In the far future life the that achieved fusion could settle things like rogue planets in deep space, so that would be another potential SETI target. Find objects emitting anomalous infrared in the interstellar void. The advantage would be being far from destructive events like solar storms.
Captain's Log: Since we came to orbit Venuuil III to host talks between the Klingons and the Venullians, there has been a increased incidence of unpredictable fluctuations of plasmas in the warp drive containment field. We are now devoting all available power to increasing our computer's ability to track and predict this rapidly changing phenomenon. Geordi reports that at the current growth factor we can maintain containment for 22 hours, 47 minutes, 17 seconds. To support the peace talks, we will remain here as long as possible.
Captain's Log: Intriguingly, the fluctuations are beginning to reveal an embedded temporal distortion that exhibits language like patterns. Data has begun working on an interface between the containment field and his positronic neural net.
What a series, I really need to read them again.
Control strategies in nonlinear systems are an effectively huge search space, and deep learning is just one way to find a good-ish solution faster.
Edit: to add some numbers, the "planned" DEMO power plant (the hypothetical successor of a successful ITER experiment) would produce something like 750MW, while Three Gorges Dam produces 22,500MW. Even if DEMO could be scaled up (which is hard, given that it would already be beyond the limits of today's material science), it definitely couldn't scale up 30 times.
I'm being entirely serious. Even though the visualization of the reactor was wildly off the mark, this specific concept fits what the writers had in mind with the AI mechanical limbs.

Da fuck? The mechanism is compression. This is like calling "generating electricity via a generator", "cognitive energy".
What is ITER? Black Magic that happens to cause Fusion?
Inertial confinement has sort of achieved this but only on paper. If you tally up the total input to set up and run the system it’s still way in the red.
ITER has the potential to run just a bit over unity but it’s really just a research platform.
I mean that is a cool scifi story, but economics seems to hate cool things.
There's this "big lie" that fusion people imply that it will be cheap, clean, and limitless.
Cheap is doubtful, clean is undermined by the reality that fast neutrons from fusion degrade the reactor to radioactive isotopes, and ok the fuel is pretty much limitless
Now, if we can get scalable fusion as viable load levelling, to develop it to the point it can be used in space then that's some real scifi.
But then there’s Helion. If you can extract electrical power directly rather than through heat exchange and a turbine, it changes the equation drastically. So I think their approach can work from a theoretical point of view.

Sabine has a good review of it:
And has been rapidly emerging for 60 years...
The plasma in the Safire reactor has self-containing magnetic fields and doesn't need the $20billion+ super-magnet infrastructure. A Safire reactor costs under $20-million to build, and probably much less these days.
The Safire reactor can keep the plasma lit and going for hours if not days without interruption. The Safire reactor has been around for over seven years now.
What matters is how we build Tokamak's has changed. A huge notable difference are the magnets used for example.
Commonwealth are using cutting-edge high-temp superconductors which can generate much stronger fields:
The idea is old, the tech is new.
Helion would have to ship something that gives positive net energy first.
Sure, they have prototypes, but we don't know how well they are currently performing
We know that helion is able to recover 95% of the energy of every pulse. And they've measured the scaling laws. There doesn't seem to be anything that will prevent net positive energy in the reactor they're building right now.
The results of the Safire type 3 reactor rendering radioactive material benign were done by a third party, which means independent, laboratory. They literally spell this out in terms that even a complete idiot can understand in the documentary you just pointed out. Hence why a very small part of their team spent some documenting what the science team did to make Safire type 3.
But I've never heard of SAFIRE. I've been on their website, and I can't find anything explaining what SAFIRE is and especially nothing about why it's so much better than a Tokamak. I can't find anything peer-reviewed.
All their marketing materials are leaving a very bad (e.g. pseudoscience) taste in my mouth
Here is what was shared, including some raw video footage, of what happened when a small tungsten rod was exposed to plasma in a Safire type 2 chamber. https://vid.puffyan.us/watch?v=7y46wMAHnsI
But since ITER was designed decades ago, we're stuck with a massive, expensive, outdated beast that's taken so long to build it will likely end up being lapped by other projects.
At least NIF has something to show for it. ITER feels like building the Vasa.
And the improvements have not made tokamaks sensible. Even higher field magnets don't rescue the tokamak concept from practical irrelevancy.
They'll work on it even if there is no hope of commercial fusion power, simply for academic kudos. Government's will fund it simply because there isn't much other blue skies physics research to fund.
Unless they are literally coming straight ahead at us!
- vs fossil fuels, almost limitless fuel with no greenhouse gas emissions
- vs nuclear fission, more fuel compared to current designs (though breeder reactors could essentially use any piece of rock as fuel), and shorter lived but even more toxic outputs (at least for D-T fusion, all pieces of the reactor become highly radioactive materials after 10-20 years)
- vs renewables, it has the advantage of being decoupled from weather and day/night patterns, but it is more expensive, it requires fuel, and it produces much more toxic outputs
You don't need a wonder technology to cart around the solar system, well, unless you are talking ECONOMICAL technology.
I'm not sure how expensive H-bombs are to make at scale.
Note that when I say self-sustaining, I don't just mean power, food, air, and water. I mean everything that a high-tech colony actually needs - plastics, machined parts, microprocessors, software, and so on.
For that matter, if a space colony is equipped with a mirror for concentrating the sunlight needed to illuminate the inside as if it were Earth, and we place the limiting distance as that at which the mass of the mirror is equal to the mass of the space colony, the distance is about 1 light year.
In the documentary they published, they do waste the viewer's time with "look at this lab we built", but if they feel passionate about telling the story of their journey, that's fine. Also in the documentary, they share some of their data and what they did to validate that data with a third party.
My comment that it doesn't seem like "serious science" means that I'm going to ignore anything not peer reviewed and I suggest others do the same.
I honestly still wish them the best, they just have a lot of work to convince anyone they're really dealing with anything new or interesting, and I don't think that video production is the path to that.
NIF is a nuclear weapons research program, as are all other (non-scam) ICF designs. Other MCF designs are either more-or-less legal scams (such as the MIT-derived startup claiming to build a working fusion power plant by the end of next or year or so), or woefully under funded.
I disagree, in two ways.
First, ITER is itself not a serious attempt at a fusion research program, although there is great pretense that it is. There is no plausible route from ITER to a practical reactor, even if it achieves every one of its goals.
Second, there are other attempts that are, IMO, much more promising. Helion and Zap are the two that come to mind.
The designs for actually capturing that energy, and for replenishing tritium, are a bigger hurdle, but there are plausible technical solutions.
Helion in contrast seems entirely a scam, promising and failing to deliver results year after year. Zap energy seems to at least not make false timeline promises, but it is trying out a much less proven concept in a direct commercial venture - not a promising way to do novel research.
Note that I am very skeptical that fusion power is a plausible economic approach to power generation, and do personally believe that all known approaches will fail to deliver a power plant that is economically viable. The amount of power that is plausible with all current approaches seems far too low to justify the immense engineering costs, and the benefit of abundant fuel is just not that impressive when you have solar and wind as alternatives.
The fact that they take a closer look at interesting power generation possibilities is a fringe-benefit: that's just scientists being thorough, but it's not why it was built. It's a bonus.
If you sincerely believe they are scam artists, then please explain something for us.
The finding, shared at the EU 2017 conference here https://vid.puffyan.us/watch?v=7y46wMAHnsI , documented on video, is an example of a Langmuir probe (a tungsten rod) evaporating.
After the tungsten rod evaporated, the Safire team tried a much larger tungsten rod which did not immediately evaporate, but rapidly decayed, as was documented.
If the Safire team is a team of scam artists, how were they able to do something new that had not been done* before?
Is there any example of this given before year 2017? Is any other team able to take credit for this finding?
[*] done unclassified, many suspect this knowledge was already attained in classified (as in national security secrets) type environments.
>> your claim does not show up on Google.
I want to make sure I answer your question, can you narrow down which claim you are asking about?
As far as "which laboratory verified the results of the Safire type 3 reactor rendering radioactive material benign?", I will reach out to them and just ask them.
So as long as no reputable independent team is a able to verify their claims, I'll remain extremely sceptical. So far all we have are wild claims and fancy videos all from a single source and that just won't cut it to convince me.
>> sustained plasma is owned by fluorescent lighting
This is an NPC "I deliberately misunderstand the argument" tier response.
>> I don't think that video production is the path to that.
If you aren't intelligent enough to see in the raw video footage that you are looking at something new and novel, that's not their problem.
That said, their materials have been published and reviewed. You can find them if you look. I'm not here to spoonfeed you.
What does intelligence have to do with seeing a video? To make an analogy, you think you'd be able to discern Intel Pentium IV from 14900K from a video footage of a working processor that would have its model number scraped out?
Fusion is just going to produce light of a certain spectrum. I don't think your brain is good at spectrometry.
The raw video footage of the multi-layered plasma fusion reaction in a laboratory conveys meaningful and complete information, directly validating the larger assertions made by the Safire team. The information is right there.
If you are not able to comprehend what is right there on video not just in one place but many videos over several years, and you still want to present non-arguments against it, then you aren't very intelligent. Simple as.
>> you think you'd be able to discern Intel Pentium IV from 14900K from a video footage
The topic is not about CPUs, the topic is about plasma fusion.
>> Fusion is just going to produce light of a certain spectrum.
The fusion in question shows multiple separate plasma layers, this key information is literally shown in the video in question, not mere spectrometry.
You argued against novel scientific information conveyed in raw footage providing proof of the scientific claims made. You don't even know what the video is yet you present a bad argument where you don't even know what it is you are arguing about.
What a fucking waste of time. God damn you are stupid. You should be ashamed for posting such garbage.
edited: clarified video footage
As far as I am presently aware, a Farnsworth Fusor has not produced multiple plasma layers.
>> but not useful for a sustained fusion reaction.
The plasma in Safire meets the definition of "sustained fusion reaction", but whether this particular sustained fusion reaction is useful or not is a legitimate bigger question.
Perhaps I am biased because, most of my experience with plasma chambers has been involved in physical presence in laboratory settings.
>> I did my masters in Tokamak simulation
I think "simulation" is the key difference between what you did and those who are doing real laboratory work. Tesla lamented that too much in theoretical mathematics was being done in place of lab work.
I am honestly very disappointed that the essential characteristics between a Safire type 2 chamber and a Farnsworth Fusor are so clear to me, yet someone who has a "masters" (implies master degree) seems to struggle to spot the differences quickly.
The guys from the LLNL team were keen on immediately recognizing the differences, so no need to lose faith in humanity or anything here, but still, do they just give out masters degrees like candy now..
This just shows that you have no idea what you're talking about. Not only does Tesla predate the whole field of computational physics, but computational physics is distinct from both theoretical mathematics and lab work.
And I asked a simple question-- how is a SAFIRE constructed or operated? Still no answer!
Just FYI. You're not effectively refuting the pseudoscience claim with this.
Here's a hint if you need it spelled out for you: nobody gives a shit if you think this is "science" or "pseudoscience".
You yourself admit the economic problem, which is not separate from the notion of practicality.
Helion and Zap energy will more likely never be able to supply power to the grid at all for physics reasons, regardless of economics (assuming of course they don't entirely change course and move to a tokamak-like design).
Helion and Zap have larger physics barriers, that's true. But the goal isn't to produce a pyrrhic victory and a power plant that "works" but can't compete. The goal is competitive energy out. I contend Helion and Zap are both more likely to reach that actual practical goal than DEMO.
The Safire plasma team doesn't even announce "weRe doinG ScIeNCe", all they are doing is presenting "here's what we did, here's what we found".
If you believe what they did "isn't science", then what you believe is not "they didn't follow the scientific method", what you believe is they did not do Science™ which amounts to orthodoxy ie religion.
As far as I have seen from the Safire plasma team, they run experiments and share their findings, then make hypothesis and run more experiments and share more findings. I have watched them do this consistently over several years.
If you want to argue that they aren't doing the "scientific method" when you aren't even familiar with their years of work, you are very stupid and may God have mercy on your soul.
A scam artist would not be able to originally discover and present such a result.
>> So as long as no reputable independent team is a able to verify their claims
The Safire team has worked directly with LLNL, which is as "reputable" as Science(TM) gets.
>> The EU 2017 conference is not a science conference
Nobody said the EU 2017 is not a Science(TM) conference. The Safire team is just one of many speakers there.
Let me state this again, I do not trust them as a source. I can't find any information regarding any Safire and llnl collaboration as well. Especially nothing from the llnl side.
I respect your skepticism.
>> any information regarding any Safire and llnl collaboration
What I know about this information is from about six years ago, which is what I can tell you today. I probably have it saved somewhere.
>> Can you please give me evidence for anything you have written in this thread that did not originate from Safire or aureon?
The short answer is yes. Separate from that, I also have access to two of their laboratories later this year. This is contingent not on their willingness to allow me access but my own itinerary for the year.
>> To make an analogy, ...
> The topic is not about CPUs, the topic is about plasma fusion.
I mean if you can't comprehend word "analogy" in a simple sentence, what makes you think you can reason about scientific claims?
What goes on inside of the Intel CPU you specified is not visible to the naked human eye.
Considering the scales very obviously involved (if you bothered to look), it's harder to come up with a dumber analogy than the one you presented.
Do you realize how many bright gazzy things have visible layers? Hell, even a match flame has visible layers and is also part plasma.
>> itS buLlSHiT
amounts to autistic reee'ing
At least I understand the concept of scientific proof. And "thEre'S A viDeO oN teH iNteRweBs!" doesn't cut it.
Have a nice life.
Basically, ITER/DEMO has a low chance of being economical even if it works physically. Helion and Zap have a higher chance of being economical if their approach works. I think we both agree on these points.
Where we differ is that I don't believe it's plausible that Helion or Zap's approach will work at all. But this is just a belief ultimately, I'm not basing it on any objective facts or anything like that.
Suppose one were trying to take advantage of heat provided by fire, they would want to exploit how fire naturally behaves to get the benefit, rather than attempt to force fire to behave a certain way to get the benefit.
I actually do much appreciate that you point this out.
A while back working with a group I had pointed out that "fire is a cold plasma" and that there were electrical properties to fire. I got scolded by those of Soyence orthodoxy for saying such things. A US Navy patent reveals a fire-fighting technique that projects an "ionic wind" that "cuts the circuit" at the base of a fire, which had also vindicated what I was talking about.
>> In both cases you can't see the important parts: calculations/energy conversion
The layers they postulate were very clearly visible to the naked eye.
>> Hell, even a match flame has visible layers and is also part plasma.
These layers were not postulated. Another analogy.
>> Nah, the analogy is excellent and

Thanks, but I am done. You're too stupid. Too bad you will forget about that by the time that pseudoscientific snake oil company collapses.
This is way over the line at which we ban accounts. I'm not going to ban you right now because you've been here a long time and it doesn't look like your account has a long history of being abusive. But please don't post like this to HN again.

And the only naturally occurring plasma hot enough for fusion is in the cores of stars, where gravity, not magnetic fields, keep it contained.
>> the only naturally occurring plasma hot enough for fusion is in the cores of stars
Plasma that is artificially created is still plasma, not unlike how fire that is artificially created is still fire.
That plasma can be manipulated magnetically does not change. The Safire plasma has self-containing magnetic fields. Helion's plasma does not have this.
They are basically a cold fusion scam, except they are using a hotter plasma than the original cold fusion scammers. But, per their own claims (25,000 °C), nowhere near the temperatures required for fusion (million+ kelvin). They also claim that they are reproducing the conditions of the sun's atmosphere, which is again equivalent to admitting that they can't actually produce fusion power, since fusion doesn't happen in the sun's atmosphere.
Their website contains other bizarre claims, like claiming that they "use electricity to change the nuclei of atoms" and that they "transmute tungsten and iron into 17 benign stable daughter elements". They talk about cold fusion as if it exists as well.
These people either have no idea what they're talking about, or are active scammers. There is 0 chance they are anything else. Their device might heat plasma up to 25k C, but it does nothing else.
What's most remarkable about this is that you've allowed yourself to be taken in by it. Show even the slightest level of skepticism, please.
"warm" fusion does exist, see https://brillouinenergy.com/ - some have insisted that Brillouin Energy is doing cold fusion, but I am not sure if cold fusion is an appropriate description. The Brillouin Energy team is completely external to the Safire team, though they may share some of the "controversial" views that the Safire team also holds about how electricity plays a greater role in chemistry than conventional thought. The awesomeness of the larger zeitgeist of science is that it is always changing.
As far as I know, and am interested to find out, Brillouin doesn't reach a temperature of 25,000 °C.
>> They have a working plasma, yes
The Safire plasma, on its face as shown by direct observation, behaves very differently than other plasmas, in a way that others were not able to make happen.
>> They do not, in any way shape or form, a self-sustaining fusion-producing plasma.
I think this here exemplifies how there is one set of words on the screen, and some here are reading some other set of words. This phrase you have presented has not been written anywhere else on this thread. I am not aware of any point where the Safire team wrote or uttered "a self-sustaining fusion-producing plasma".
Whatever ghost you thought you were arguing against, I don't think it exists.
That said, the Safire plasma, like other plasmas, produces heat that can be converted to electricity. Because the Safire plasma remains contained by its self-containing magnetic fields and does not require external magnets to force the plasma to stay contained, the *energy requirements of the external magnets are not required*.
Hence all that is required is the already modest amount of electricity to keep the plasma lit and a steady supply of hydrogen. Because the Safire plasma continues to run, and without the overhead of external magnets, abundant electricity can be harvested. This *does not mean* that Safire "puts out more energy than it takes in", this only means that the abundant electrical energy is being harvested from what *existing energy* is converted. This is *not* and also *no one claims* that this is somehow "free energy" nor "self-sustaining". Something that requires something external to it to continuously feed hydrogen is not self-sustaining. On this front, the Safire plasma team has only ever claimed (as far as I have seen) that they have a very efficient way to harvest usable electricity from Hydrogen ; the Safire team has never claimed that their Safire plasma chamber is or somehow could be "self-sustaining".
>> They talk about cold fusion as if it exists as well.
Cold fusion is a thing that scientifically exists. Perhaps what they have written in scientific terms, is some larger meme that you have confused the term "cold fusion" with, similar to "self-sustaining fusion-producing plasma" above.
>> These people either have no idea what they're talking about
The Safire team has created a novel plasma chamber where the plasma chamber has multiple layers and self-containing magnetic fields. If you have worked on a team that has created something similar, perhaps you know more about this topic than the Safire team, but if you haven't, they are speaking from real-world experience that they objectively do have.
Furthermore, please show me another team separate from the Safire team that has created a multi-layer plasma with self-containing magnetic fields documented to have done this before the Safire team on-record accomplished this. Pro tip: you can't.
>> Show even the slightest level of skepticism
What is it, exactly, you want me to be skeptical about?
That they have a multi-layered self-containing plasma?
That the plasma in the Safire type 2 chamber is self-containing and does not require external magnets like a Tokomak reactor?
That in their plasma chamber fusion is occurring and heavier elements are forming?
The Safire team has been, for close to a decade now, forthcoming and transparent about their guesses, about what they are finding, how often they are finding it, what they think they know, what they are confident they know, so on and so on.
To be clear, the Safire type chamber containing this plasma, has ultimately one and only one at-the-crux differentiating feature, external magnets are not required like Tokomak. The Safire team does not claim to have "invented" the concept of a plasma chamber. Hot plasma does cause fusion to occur, this is not special nor novel (and Safire team did not "invent" nor advent this either). In a Safire plasma chamber the plasma is self-containing, that's the one differentiating thing, that's it.
About 10 years ago members of the Safire team (as it is now named) shared their findings in writings. In addition to their writings they shared several hours of raw video footage of plasma regimes they had in the lab of a Safire type 1 plasma chamber.
I have watched them, albeit remotely, over the years steadily progress from their experimental chambers, to their type 1 plasma chamber, to their type 2 plasma chamber. That plasma in their approach to a plasma chamber is self-containing has never seemed to be in dispute. Hell, I could probably get one of these running in my own industrial garage if I tried to, and I wouldn't be the first one to do this.
People I personally know have met these folks face to face at various conferences. What these people I personally told me was that these plasma tinkerers were no less mild-mannered, candid, forthcoming, willing to listen, and willing to answer than they present themselves online. What I and many others have seen out of them is consistency.
If you think there is some specific detail that is highly questionable, please point out to me what you think it is. I am more than willing to carefully consider what you have to share and disconfirm what seems to be reasonably true. If you have some new information to bring forth, please do.
The saying "old science dies hard" does come to mind here.
Please help me embody the skepticism you are asking of me, you can do this successfully by addressing the very specific details you are concerned about and also by not failing to make a sincere attempt to answer the questions that have been presented to you in this response.
