Why is Fusion always two decades away and not now? It's effectively free energy and we have enough deuterium and tritum to power it forever in human scale. Will AI speed up the research?
>>544915585>It's effectively free energythis is why
>>544915585>Why is Fusion always two decades away and not now?Because you need to outdo nature.Fusion inside stars is quintillions less likely than you getting bitten by a shark inland stars are just really big so it happens often enough.>Will AI speed up the research?Not in the way you think.
>>544915585I was going to contribute to this discussion but as you're hiding your flag communication is impossible, nigger
>>544915585>It's effectively free energythat we all already use as we always did . Jews lie about shortage1905 wireless electricity in the city electrical cars and public transporthttps://www.youtube.com/watch?v=ZAiAXLhHc_c
>>544915797>Fusion inside stars is quintillions less likely than you getting bitten by a shark inland stars are just really big so it happens often enough.Why are they still pursuing it though? There's still tens of billions pouring in.
>>544915585fuck you bitch. you will have nothing and you will be happy
>>544915585Eat red pills about energy hoax https://youtu.be/m85mf8WRdhE
>>544915898>There's still tens of billions pouring in.that is a aim
>>544915898Because that's what humans do.Robots haven't worked for millenia and people tried.
>>544915585Turns out that confining plasma at millions of degrees using the strongest magnets ever created and get net energy from it is harder than it looks.
>>544916328>>544916335We have a fusion reactor in the sky why not make better efficient solar panels?
>>544915585Same reason as quantum computing is always 2 weeks away. It doesnt fucking exist
>>544915585Experimental machines have been physically built and operated, though none have yet achieved continuous net-electricity generation at a commercial scale
>>544916662Solar panels are just fine how they are right now.The problem is energy storage.
>>544915661these companies are worth pennies compared to free energy
>>544917149Oil companies will always be there even with nuclear fusion up and working. We have no substitute for the chemicals derived from oil
>>544915585Because asking people to guess when we will invent the next stage of existence is fucking impossible. How can you possibly know how long it will take to solve a problem nobody in existence had ever solved?In this case they have to also guess that the thousands of other technologies being developed to make fusion possible all advance just in time for the next stage.PS they already have most of fusion solved, they're working on getting it to all work together at the same time. Net energy gain has already been proven a few timesFor all we know chatGPT solves it tomorrow and within 5 years we have a commercial fusion reactor, except it never works in our favour because Altman claims the patent for israel after GPT stole the research of a hundred thousand scientists and put it together
>>544915585it is possible but maintaining the fusion is more expensive than the energy output
>>544917230When we have fusion we can synthesize them from carbon and hydrogen.>>544917149Yes, those companies and the petrodollar will be worthless when we have free energy, that's why it's in their best interest to never let it happen.
>>544915585Fusion neutronics PhD here, it's really fucking hard.>First wallThe stresses on the plasma-facing components is upwards from 15 MW/m2, which no modern material can sustain without melting or cracking. Disruption events raise that to 1.5 GW/m2 which leads to catastrophic damage to the machine if not mitigated, and we have no physics model for these.>Scaling lawsThe scaling laws dictate that only a large machine can create enough power to supply to the grid. ITER costs ~50 bln euros, a DEMO power plant will cost about the same, even billionaires are skittish.>Neutron damageA fusion reaction releases 10 times more neutrons per joule of energy in comparison to a fission reaction. These fast neutrons absolutely wreck steel, electronics, superconducting magnets, glass fibers, irradiate water to hell and back, so a plant will have to undergo routine repairs just due to this embrittlement.>Tritium breedingTritium is radioactive and light enough to escape Earth gravity. This means that the only T we have is the one we produce. You can generate T through the 6Li+n=a+t reaction, so a single T produces a single neutron which in turn generates a single T. Due to inevitable losses, you run out of tritium unless you fuck around with U/Be/Pb breeder blankets.>Tungsten rarityTungsten is the only thing that can survive plasma exposure, and it's rare. A fleet of fusion PPs that generates 16% of the world's power will consoom all current tungsten production, and over 90% of it is produced in China/Russia.>Confinement scheme fuckeryTokamaks are the most successful magnetic confinement schemes. They are also impulse-fired by design and have a bunch of unique and dangerous instabilities, and all other schemes are even worse.There are probably other problems I haven't mentioned, but the post is long enough already
>>544915585the initial resources to get it started are very expensive and very finite and also china hoards most of them
>>544915585>we have enough tritium to power (((nuclear fission)))That’s where you just outed yourself as being a retard. The earth has little to no supply of tritium
>>544915585Companies are moving to nanofusion because it doesn't take billions of upfront investment for a facility that may not even work.They are quickly iterating on their designs and expect small-scale operability with net energy gain in 2 more weeks.
>>544917564>The earth has little to no supply of tritiumIm nature yes, but we can breed it.
>>544915898>what is money launderingYou have to be at least 18 years old to post here.
>>544915585>It's effectively free energyNo it's not.You'd still have to build and maintain the fusion reactors.Solar and wind aren't "free energy" either for the exact same reason.
>>544917598>Companies are moving to nanofusion because it doesn't take billions of upfront investmentFuck it. Why not just move it to computer simulation software at this point? All you need is a macbook pro and cloud storage.
>>544917614Are you 12 years old?
>>54491779821 actually. Close though you got the numericals right.
>>544915585anyone hear about these copper dwellings in sibir? Apparently they are radiating what I believe to be beta-radiation and there were some deceased inhabitants who had metal suits, that would block the radiation while they would still benefit from the heat of the reaction.
>>544915898In some part, it's a pissing match between major powers, if any of them can make fusion power truly work the way it's advertised there'll likely never be another energy crisis for them again.Nobody wants to drop the ball and stop playing in case someone else finds a breakthrough.
>>544917460>european goy cattle here>blog postsgood thing you paid jews for getting your hand held. a big baby man with a college degree making reddit comments on 4chan is really smart because his paperwork said so.meanwhile AI can shit out everything you just said in a more concise and user friendly manner at a fraction of the speed it took you.which is probably how you got through university in the first place.
>>544917460Is it even possible in theory? What odds do we have?
>>544917955Why are you mad at a stranger on the internet? And what does your anger have to do with the topic of fusion energy?
>>544918097Check the flag.
>>544917691>No such thing as free energyEven a slice of toast taped butter side up to the back of a cat has initial capital investment.
>>544918014Sure it is, physically, but economically in the coming decades not so much. Very expensive laser-welded monocrystalline tungsten can survive the operational stress, and liquid lithium walls don't care about heat damage at all. Very large and expensive tokamaks can run at low-ish power and be pretty stable, and incredibly complex and ludicrously expensive stellarators can run for days without stopping. Neural net powered plasma control is quite successful at disruption prevention and instability control. You can even reduce the neutron stress and the breeding problem by surrounding the plasma chamber with depleted uranium since it is fissile under fast neutron irradiation. The hybrid design is much less demanding of plasma parameters. You get a bunch of very unpleasant radwaste, but we know how to manage that more or less, in fact, it can decay to something short-lived if you live it in the neutron flux. Currently, the tech is on the cusp of breakeven operation, that is, heat in equals heat out. Electricity in equals electricity out is 10 times harder, ITER aims to show that. Still, the material and economic challenges are really tough, and the political climate doesn't help the matters either.
I have no doubt that free energy exists in top secret labs and that it is one of the most closely guarded secrets in history. I think they mind controlled a schizo to kill that MIT plasma physicist
>>544915585Commercial fusion stays "20 years away" because igniting a brief reaction in a lab is a completely different problem from running a durable power plant that puts electricity on the grid.First, half the fuel is missing. Deuterium is easy to pull from seawater, but tritium is radioactive with a 12.3-year half-life and barely exists in nature. Global stockpiles sit at a few dozen kilograms, while a 1 GW fusion plant burns about 55 kg a year. A reactor has to breed its own fuel by lining the chamber with lithium so escaping neutrons convert it into new tritium. Nobody has run that closed loop at commercial scale.Second, lab records measure plasma breakeven (Q_plasma greater than 1), where the plasma releases more heat than the energy injected directly into it. That ignores the huge electricity draw needed to run the magnets, lasers, and cooling systems, plus the 60% loss when converting heat into steam-turbine electricity. A power plant needs a Q_plasma of 10 to 30 just to send net power to the grid.Third, the reactor damages itself from the inside. Magnetic fields hold the 150 million degree C plasma, but D-T fusion releases 14.1 MeV neutrons with no electrical charge. They fly straight through the magnetic field and slam into the solid wall, knocking metal atoms out of their crystal lattices and turning the steel brittle.Even when it works, fusion will not be free. Fuel costs pennies, so power bills will pay for the multi-billion-dollar magnets, vacuum vessels, and robots needed to replace radiation-damaged cores.AI is helping close the gap alongside High-Temperature Superconducting magnets. Deep reinforcement learning now predicts plasma instabilities 200 milliseconds ahead to adjust magnetic coils in real time, and neural networks run turbulence simulations 1,000 times faster, putting private pilot plants within reach by the late 2020s or early 2030s.
>>544915585Because it's not solved. Not even theoretically.
>>544915585> > Why is fusion always two decades away and not now? It's free energy and we have plenty of deuterium.Because you’re a midwit who thinks having a bathtub full of deuterium means you have a functioning power plant. Fusion isn't a fuel problem; it's an intractable materials science and magnetohydrodynamic (MHD) containment problem. You’re trying to contain a plasma at 150 million Kelvin. The plasma doesn't want to be contained. It throws tearing modes and edge-localized modes (ELMs) that will instantly quench your reaction. But the real kicker is neutron embrittlement. Those fusion neutrons are uncharged, meaning your magnetic fields don't do shit to stop them. They fly straight into your reactor wall and turn it into radioactive dust through displacement-per-atom (dpa) degradation. We don't have materials that can withstand that bombardment for years on end without dissolving.Then you have the Tritium Breeding Ratio (TBR). You have to breed your own tritium using lithium blankets. To be self-sustaining, your TBR needs to be >1.1. Right now, the physics calculations for most designs are sub-1.0. You're literally burning your seed corn. > > Will AI speed up the research?AI is just a glorified numerical optimizer. It’s great for tuning magnetic control loops so the plasma doesn't touch the wall for a few extra milliseconds. But AI cannot algorithm its way out of thermodynamic reality. It can't magically synthesize a superalloy that resists 14 MeV neutron bombardment. We are bottlenecked by physical metallurgy, not software. It's 20 years away because it has always been 20 years away. Stop coping.
>>544917460Thanks for the rundown Austria anon
>two chamber magnetic bottles with a constriction between them operating in alternating pulsed detonation regimeSkip the second chamber for a drive.
>why do scammers keep promising the same scam?Because you keep giving them money.
>>544920168this>in "wall street money never sleeps" the scientist needed "just another 100 million dollars" to fire 96 lasers at a single point to achieve fusion, an ever increasing number of lasers. why? because it's not real. they've been milking this goat for decades.
I thought the saying was always 50 years away
>>544917149>these companies are worth pennies compared to free energyOh so that's why we don't have free energy. Well that and retards like you still haven't come around to figure out how a fucking magnet works. In fact it's the only;y question you should be asking a quantum quack since they're about as clueless as you are when it comes to defining "energy".>>544920641It will always be "50 years" away when you you can keep building tokamak after tokamak knowing full well they won't work before you even build them/ Same with this next "impossible drive" in germany. Woooow you too the same tokamak...twisted it like your fucking pretzel (again) and (again) it still didn't do the magic magnetic thing (because the retards who build them with your taxes still don't know how a fucking magnet works).
>>544920918Literally >They don't even try looking for the answer anymore, while begging for more money for more super cooled magnets so their "particle" accelerator can keep functioning. Ask any one of them at CERN "how a magnet works" and they just look at you like this
>>544915585Because we should whip those scientists harder!
>>544915585 They always say it's a "breakthrough". In reality, however, commercially viable fusion isn't much closer than it was back in the 80s. While most honest writers have at least acknowledged the obstacles to commercially-scaled fusion, they typically still underestimate them, as much so today as back in the 80s. We are told that a fusion reaction would have to occur "many times a second" to produce usable amounts of energy. But the blast of energy from the LLNL fusion reactor actually only lasted one tenth of a nanosecond. Apparently other fusion reactions (with a net energy loss) have operated for a few nanoseconds, but reproducing this reaction over a billion times every second is far beyond what researchers are even contemplating. We are told that the reactor produced about 1.5 times the amount of energy that was input, but this only counts the laser energy that actually struck the reactor vessel. That energy, which is necessary to generate temperatures over a hundred million degrees, was the product of an array of 192 high-powered lasers, which required well over 100 times as much energy to operate. Third, we are told that nuclear fusion will someday free up vast areas of land that are currently needed to operate solar and wind power installations. But the entire facility needed to house the 192 lasers and all the other necessary control equipment was large enough to contain three football fields, even though the actual fusion reaction takes place in a gold or diamond vessel smaller than a pea. All this just to generate the equivalent of about 10-20 minutes of energy that is used by a typical small home. Clearly, even the most inexpensive rooftop solar systems can already do far more. A group at Stanford University has calculated that a total conversion to wind, water and solar power might use about as much land as is currently occupied by the world's fossil fuel infrastructure.
>>544917460D2 fusion creates that neutron. You are implying it doesn't. You use deuterium fusion neutron to breed tritium. That T is bonus power.
>>544921351>"just do away with fossil fuel infrastructure bro trust me bro, then we will have tried true communism"
>>544915585Its always 2 decades away because there is one 'problem' between us and having functioning fusion, and if we can just solve that one problem we can speedrun the rest of it.Unfortunately, that problem is having controlled fusion that produces more energy that it takes to run it and doesn't destroy itself. Its just one problem, but its turns out its a real doozy.
>>544921619kinda like climate change, throw thousands of trillions at it that is the only problem, instead of ending world hunger with just one trillion today.
>>544921711nah who am i kidding, AI on behalf of pacha mama is going to spend 90% of all world resources, such a pity we have to cull the human population by 90% to make it work, oh well AI will have a blast
>>544921711>ending world hunger with just one trillionAnd what will you do when the niggers, now well-fed. multiply tenfold without scaling up their food production at all and get hungry again? Throw 10 trillion at it? Then 100?

>>544915585it used to always be 50yrs away
>>544921903we just have to make them stay in africa then
>>544921465D2 fusion at optimal DT temperatures is about 100 times less likely than DT fusion, so you can't replenish lost T using the DD neutrons generated by the same plasma. Optimal DD temperatures are in the range of 200+ keV which is far beyond any modern or even conceptual fusion device.
>>544915585Real answer: material science hasn't caught up to the math and physics; we know it's possible but for it to be a continuous self-sustained reaction there needs to be a few more breakthroughs that makes it feasible for commercial/industrial use./pol/ answer: jews won't allow us to escape their plans. Infinite energy means a large portion of humanity can eventually escape their grasp and go into space where they can populate the universe with antisemitism (natural reaction).
>>544915585it's a scam. just like AI, Going to Mars, free energy et al...
>>544915585>Will AI speed up the research?YES
the powers that be only want chinese commies to survive by the way, all the rest of the races will die. Because they want obedient cattle, and also I think it was nostradamus who predicted the yellow race taking over the earth.
