It's also gotten picked up by WaPo as well, sounds like at least something interesting has happend. As another poster pointed out though, is it net gain from the total system or just the laser/containment piece? https://www.washingtonpost.com/business/2022/12/11/fusion-nuclear-energy-breakthrough/ quote:The Department of Energy plans to announce Tuesday that scientists have been able for the first time to produce a fusion reaction that creates a net energy gain — a major milestone in the decades-long, multibillion dollar quest to develop a technology that provides unlimited, cheap, clean power.

It's a shame USPol doesn't have the equivalent to the clancychat rule of the Ukraine war thread, it's pretty loving wild to read goon fanfic about how fusion plants are basically H-bombs waiting to go off. Fission power plants, which are in use today, are sort of similar to fission weapons in that the fission "pile" has a chain reaction going on, which is moderated by neutron absorbers and kept from going super-critical (which is a nuclear bomb). Nuclear fission is a process where very heavy elements (typically uranium) undergo spontaneous fission, which means that the nuclei of the heavy stuff split up, which releases energy. This energy is then typically used as the driving force of a steam engine of some description, where the heat captured from the fission pile is used to, well, heat stuff up and that is then converted into electricity by means of some mechanical apparatus. This process has some unwanted side effects, such as the released neutrons "activating", i.e. making radioactive, materials around the fission pile. A fusion power plant works like the Sun does, or at least that's the idea. Light elements, or their nuclei, fuse together to form heavier elements, and this also releases energy due to marvels of nuclear physics and specifically how atomic binding energies work out. The trouble from an engineering perspective is that the core of the Sun, or any working star for that matter, is what we in the sciences like to call "extremely hot". In the temperatures we're talking about here, matter exists in a form called plasma, which basically means that it's hot enough that the electrons that in normal matter go 'round the atomic nuclei are in fact split off from the nuclei. This means that the atomic nuclei, which have a positive electric charge, and the now-free electrons, who have a negative electric charge, move around independently, and once this electrified soup becomes hot enough, the nuclei start interacting with one another which causes the fusion reaction we're after. Now, it's somewhat of a good thing that plasma is composed of electrically charged particles, because we can use https://i.imgur.com/nB7z6a1.mp4 to (try to) contain the plasma of our fusion reactor. A fairly popular idea, that is utilized in ITER for example, is to force the plasma into a donut shape with magnetic fields. This is also where the big engineering problems show up. First of all, to make the magnetic fields required to contain the plasma donut takes up a lot of electricity. And the containment process cannot be perfect, we will always have plasma escaping its magnetic cage and smashing into the walls of our reactor, which understandably slowly destroys every material known to man, and figuring out what kind of stuff to use for building the walls of our reactor is a Big Question in materials science. And our bright idea of using magnetic fields only really works for charged particles, but when we're talking about nuclear physics, there's always those drat pesky neutrons around, and as per their name they're electrically neutral, and our magnetic fields don't exert a (lot of) force on them. So they will mash into our reactor walls, too, activating stuff and making nuclear waste. Oh, and as mentioned earlier, the plasma has to be hot hot hot, and heating it up to Sun-level temperatures also requires a lot of electricity. All of this is to say that a nuclear fission pile will merrily fission all by itself, hence the idea of a critical mass, where the chain reaction of nuclei splitting up releases enough neutrons that they in turn cause other nearby nuclei to fission, releasing more neutrons, and you can see where the moniker chain reaction comes into play here. A nuclear fusion reactor, in contrast, is very much an artificial, engineered thing that is forced into its configuration by a lot of expended energy. If anything should fail in a fusion reactor, the fusion process will just stop, either because the magnetic bottle fails and our plasma dissipates and smashes into the surrounding walls, or our plasma cools down from the required insane temperatures and there's not enough energy around for our nuclei to fusion. The entire problem with fusion reactors is that we have such trouble creating a macroscopic volume of space where plasma can exist in the first place! It's insane to suggest that the fail condition of any terrestrial fusion plant would be "turning the surroundings into a crater".

It's just that once we finally hit the break-even on energy generation and go to commercial usage future advances might end up doing something to cause a catastrophic breakdown that we literally cannot foresee now. TL;DR: I was being glib while also pointing out that human stupidity and greed is about as great as human ingenuity and aspiration, and if at some point in the future it can happen due to currently impossible to know variables someone looking to cut corners will face fault their way into doing it. If this hasn't somehow made it clear to you: It is decidedly not possible for a fusion reactor, Tokamak or otherwise, to explode now. Nor is it likely to in the span of any foreseeable future. Doesn't mean i'm not going to snark about fusion when we've got basically gently caress all to say that this new breakthrough is reliable until it gets reproduced by other scientists that can verify that it's a real thing that doesn't gently caress the reactor up for future sustained usage.

Fusion requires extremely hot temperatures that are extremely difficult to maintain for a variety of reasons. Also, we have absolutely have ran reactors for limited amounts of time that reached temps over a 100 million degrees. The hottest to date that I know of was around 150 million Celsius. Obviously there's no material on earth that can handle touching anything that hot, so the solution is to suspend it in some way. If the suspension mechanism fails (Which is possible, though given that these aren't day to day commercially used reactors unlikely.) then you may or may not end up having an extremely hot ball of plasma slagging a part the reactor before it can finish terminating.

If the suspension mechanism fails then you have an extremely hot ball of plasma slagging a large part of the hull of the reactor before terminating. Again, this is missing the forest for the trees. You stated, and let's quote it here to be clear, Archonex posted:I apologize if i'm wrong but the problem that I sort of recall reading is that containing a reaction slowly (and sometimes in at times very bad situations not so slowly) slags whatever containment they have and if the shutdown sequence or certain parts of the reactor experience a total failure then oops now you basically have a superb bomb that can and absolutely will immediately vaporize the building along with everything in the locality of the power plant due to potentially as much as 150 million Celsius temperatures (depending on the scale of failure or Chernobyl style mismanagement and intentionally bad design.) and equivalent pressure rapidly expanding outwards if it it isn't shut down. And now you are citing a paper that says that within a very, very small volume of space did a team of scientists manage a temperature of 150 million degrees Celsius. This does not amount to anything resembling "vaporizing buildings along with everything in the locality". Here's an example that might be instructive. What's the temperature of planet Earth? Where I'm sitting, it's literally freezing outside, and the streets are full of ice and snow. Not fun! But, the Earth, as a whole, sits at around 15 degrees Celsius year round. The local temperature is a meaningful measurement when one is considering what to wear outside that day, and we look at the global temperature when we're trying to figure out if the globe is on fire. (Spoiler alert: It is.) We have all sorts of particle accelerators and other scientific instrumentation of the sort where you can, locally, in a very small volume, create exotic environments. This does not, again, translate into somehow magically turning whole blocks of streets into 150 million degrees Celsius weather.

Please note that I did not say that the fossil fuel companies will make it impossible to switch to fusion energy, just that they will make it harder and take longer.

https://www.yahoo.com/news/thousands-youths-compelled-join-militarys-154348130.html article from the NYT (yahoo link to avoid potential paywall) about compulsory enrollment of high school students in JROTC, disproportionately affecting schools that are majority black and Latino. When challenged, some schools back off on the policy but others make it difficult or impossible to unenroll students from the program. Enrollment is being done without informed parental consent. The military claims JROTC is not part of recruitment but schools with such programs statistically have far more students that go on to join the military and the schools are incentivized to do it because the education arm of the military picks up the tab. This is happening during a time with sharply decreased military enrollment.

Yeah, I don't think this is because these random schools want to become fascist recruitment centers. It seems like this is the latest creative method that schools have found to raise money/cut costs and fix attendance/discipline problems (and attendance rates also impact funding in some places, so this is itself just part of the overall effort to raise money/cut costs). The schools that do this are almost exclusively in low-income areas with student bodies that are over 80% POC.

No final deal reached, but negotiators say they are close to agreeing to an outline to revive the expanded child tax credit that will get 10 Republicans + Manchin to support. Democrats would vote to extend some research and manufacturing tax credits for businesses that were implemented in the Trump Tax Cuts and Covid stimulus bills as part of the package. Republicans would vote for an entire year's budget with no continuing resolutions and the new child tax credit. The new version would be extended for "multiple years" and would be structured slightly differently than the previous one. The main differences from the previous expanded credit: - No monthly payments, you get it all in a bulk payment once per year with your tax refund. - Income cap will likely be lower than the previous $150,000 cap. - A "work requirement" that requires that you either have earned at least $1 in taxable income for the year, certify that you have applied to a job in the last year, or get an exemption by certifying that you are a full-time caretaker of the children or are exempt from the requirement for other reasons (the normal child tax credit already required you to have some income. The first expanded credit waived that. This one doesn't waive it, but does add several new exemptions to let you qualify even if you didn't earn at least $1 in the tax year). It still makes the credit fully refundable, so people who only get a partial payment or don't pay any taxes right now can now claim the full value of the credit. It is expected to cover roughly 19 million. None of these details are finalized and they are still hammering out the structure of the deal. This would be part of the full omnibus budget that needs to be passed by December 16th (unless they pass a continuing resolution to delay it). https://twitter.com/adamcancryn/status/1602302431425183744 Leon Trotsky 2012 fucked around with this message at 17:40 on Dec 12, 2022 |

Indiana Senator Mike Braun plans to run for Governor of Indiana and resign his Senate seat after 2024. Seems very unlikely to make much of a difference in the Senate because a Democrat is unlikely to win and most potential Republican replacements will likely vote functionally the same. Former Governor Mitch Daniels is said to be considering a run and may be slightly open to certain bipartisan votes, but that is more of a tactical difference than an ideological one. The other likely candidates on the Republican side are Reps. Jim Banks and Victoria Spartz. https://twitter.com/burgessev/status/1602342659527524352 Louisiana Senator John Kennedy is also considering resigning his seat to run for Governor of Louisiana in 2023.
