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

Even the core only has an output of 200-300W/m^3.

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.

And only 12 seconds to regret.

And keeps you sated for another 22 seconds.

Then you want seconds.

That was such a culture shock when I went to the us for the first time.

In Germany and many places in Europe do not think of burgers as sandwiches. I was so confused when I ordered a sandwich and got something like a burger.

I expected something like this. My confusion must’ve been quite the sight, the waitress even seemed concerned. Tasted great though.

But I’m le tired.

It’s not the size the matters, it’s the amount of hands that matters.

But pushing for more renewables can also be a way to stop fascism. Those texan oil barons are funding Trump exactly because they want to keep their business. Putin is funding all those right wing parties because he wants to keep selling gas. And the Saudis, Qataris and other dictators are also not to keen on not selling oil and gas.

‘Boinks’

People fall off rooftops fitting solar panels, burn to death repairing wind turbines that they can’t climb down fast enough to escape, and dams burst and wash away towns. Renewable energy is much less killy than fossil fuels, but per megawatt hour, it’s comparable to nuclear, despite a few large incidents killing quite a lot of people each. At the moment, over their history, hydro is four times deadlier than nuclear, wind’s a little worse than nuclear, and solar’s a little better. Fission power is actually really safe.

The article’s talking about fusion power, though. Fission reactions are dangerous because if you’ve got enough fuel to get a reaction at all, you’ve got enough fuel to get a bigger reaction than you want, so you have to control it carefully to avoid making it too hot, which would cause the steam in the reactor to burst out and carry chunks of partially-used fuel with it, which are very deadly. That problem doesn’t exist with fusion. It’s so hard to make the reaction happen in the first place that any problem just makes the reaction stop immediately. If you somehow blew a hole in the side of the reactor, you’d just get some very hot hydrogen and very hot helium, which would be harmless in a few minutes once they’d cooled down. It’s impossible for fusion power, once it’s working, not to be the safest way to generate energy in history because it inherently avoids the big problems with what is already one of the safest ways.

cheaper,

Once commercial fusion comes out, it’s likely to be about half the cost of wind.

[more] reliable

There’s absolutely no way to know how reliable human-generated fusion is, but it powers every star in the sky for billions of years, so it could probably last for a few decades here on Earth without much trouble.

and safer alternatives

Nuclear fusion, when begun, creates water as its byproduct. This water is, admittedly, very slightly radioactive; if you drank the “nuclear waste” that is produced by a fusion plant as your only source of water, it would increase your radiation exposure the same as if you flew from New York to Los Angeles and back once per year. Now, that’s not nothing, but it is almost nothing.

As for large-scale disasters from nuclear fusion, that’s almost impossible—and you can see why by the fact that this very article is news. With a nuclear fission reaction, the difficulty is in containment; get the right things in the right place, and the reaction happens automatically. There are natural nuclear fission reactors in the world, caves where radioactive materials have formed in an arrangement that causes a nuclear reaction. But in order for nuclear fusion to happen on its own, you need, quite literally, a stellar mass. So if something goes wrong in a fusion power plant, where we’re manufacturing the conditions that make fusion possible at great energy cost and effort, the reaction just stops unless there’s a literal sun’s worth of hydrogen hanging around. It cannot go critical, it cannot explode, it cannot break containment; it can only end. It’s hard to sustain a fusion reaction, and that’s why stories like this are news: because it’s a major breakthrough anytime we get closer to a reaction where we can feed enough power that it generates back into the machines that keep it running. Once the power to those machines is cut, a fusion reaction cannot continue.

Wait, what is the cheaper alternative to the moon landing?

The space race gave us space age materials and advances. It wasn’t for nothing.

So much has manifested in the ripple effects from the pursuit of great things.

It’s several cooperative and competitives projects. Diversity is not bad for science anyway. ITER itself involve tons of countries.

I should’ve replaced ‘quite’ with a more clear ‘remotely’ but you’re absolutely correct

In just 10 more years, it’ll only be 40 more years!

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.

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?

OK, so we should be clear there are broadly two approaches to fusion: magnetic confinement and inertial drive.

In magnetic confinement a plasma is confined such that it can be driven to sufficient density, temperature and particle confinement time that the thermal collisions allow the fuel to fuse. This is what the OP article is talking about. This Tokamak is demonstrating technologies that if applied to a larger the experiment could probably reach a positive energy output magnetically confined plasma.

The article you referenced discusses inertial drive experiments, where a driver is directly pushing the fuel together, like gravity in the sun, a fission bomb shockwave in a hydrogen bomb, or converging laser beams in Livermore’s case.

Livermore’s result is exciting, but has no bearing on the various magnetic confinement approaches to fusion energy.

In my experience the community will usually distinguished between “scientific Q” and “wall plug Q” when discussing fusion power gain. Scientific is simply the ratio of power in vs power out, whereas wall plug includes all the power required to support scientific Q. Obviously the difference isn’t always clearly delineated or reported when talking to journalists…

Inertial confinement doesnt produce a “stable reaction” it is pulsed by it’s nature, think of it in the same way as a single cylinder internal combustion engine, periodic explosions which are harnessed to do useful work. So no the laser energy is required every single time to detonate the fuel pellet.

NIF isnt really interested in fusion for power production, it’s a weapons research facility that occasionally puts out puff pieces to make it seem like it has civilian applications.

Move zig move zig move zig, you know what you doing take off every zig!

HNNNGG, right in my nostalgia.

Time for another reread I suppose.

Hahaha thank you for this gift

The ironic thing is the human body runs on fat and a huge portion of our illness stems from the insane amount of sugar we consume.

Summary: In 1984 our group published the first modern study of the effects of adapting to a low carbohydrate high fat diets on athletic performance. I have spent the next 31 years expanding on this research. In my presentation I will present the results of that research program and conclude with our exciting new evidence for the role of low carbohydrate diets and ketosis in the prevention of whole body inflammation in athletes training daily at very high loads. I will also present evidence to show that elite ultra-endurance athletes have an unexpectedly high capacity to oxidize fat during exercise and so potentially to run at fast paces for prolonged periods without the need to ingest exogenous fuels.
