Submission + - Chinese Fusion Reactor Breaks Plasma Density Limit (futurism.com)

hackingbear writes: Scientists at China’s Experimental Advanced Superconducting Tokamak (EAST) program rang in the new year with a stunning accomplishment: empirical evidence that they used the device to achieve nuclear plasma densities once thought to be beyond human capabilities. To reach a point where fusion reactor can power itself — a sustainable fusion reaction — requires that gnarly plasma to stay hot, dense, and stable for long stretches of time. For years, it was understood that higher plasma densities would inevitably result in instability, collapsing the fuel before it could ignite, a threshold known as the Greenwald limit. In deuterium-tritium fusion, the fuel must be heated to about 13 keV (150 million kelvin) to reach optimal conditions. At such temperatures, the amount of fusion power produced increases with the square of the plasma density. This new research seemingly flips all that on its head. As the EAST team explains, the method basically involves creating a high gas pressure environment in the reactor prior to plasma formation, which allows the plasma to interact with the reactor wall in a much less destructive way than it would otherwise. Scientists also manually pump extra energy into the plasma as it heats, allowing an even rise in density. The result is a plasma that remains stable even as its internal density rises, resulting in fuel densities “far exceeding empirical limits.” While there are still plenty of breakthroughs left before humanity achieves practical power production with fusion, shattering the Greenwald represents a major item on the to-do list — and another notch on China’s lengthy green energy belt.

This was an inevitability, and not just because of the tightening job market. The real gasoline dumped on the tire-fire of employment (especially tech employment) in the United States is AI. It used to be that, when I posed a job opening, I got maybe 100 applications over the course of a few weeks from people who moderately embellished their resumes. And that's because the conventional wisdom was to spend the time to put together a really class-A application to the jobs that were the best fit for you.

But AI has changed the math.

Now the hours-long process of fine-tuning your resume to fit a job description and crafting a nice cover letter to go with it are the work of a click or two. Candidates have every reason in the world to apply to as many jobs as they can. It's a classic prisoners dilemma; sure, everyone else is worse off if the HR departments are flooded but if everyone else does it and you don't, you're never going to land a job.

And so the firehose opens and the job ad that used to get me 100 resumes over the course of a month gets me 1,000 resumes over the course of an hour.

And, just for funsies, most of them are wildly unqualified. AI is happy to lie on your resume for you and getting it not to do that is hard. So now not only do I have a ton of resumes to go through, I have a crisis of trust on my hands. Who, out of all of these applicants, are telling the truth and who's basically echoing the job-ad back to me?

In that situation, it makes a ton of sense to lean back on trust relationships. Harvard, MIT, Stanford, etc have reputations to uphold. I can count on them to police their candidates. My local university wants to maintain a good relationship with area businesses; if their graduates are BSing me in their resumes I can meet the head of their career center for coffee and get them to deal with it.

There is no solution here. The employment market is a feedback loop. The bigger the applicant:job ratio grows the harder it is for employers to adequately consider and respond to applications, turning the application process into something more akin to a lottery ticket than a proper application. The more converting an application to a job feels like random chance the more incentivized applicants are to prioritize quantity over quality, driving the ratio ever higher.

Nothing short of a sudden and profound cratering of the unemployment rate is going to slow this arms race. This isn't the end state of the market; it's going to get worse before it gets better.

In Finland in the early 90s we also had to read complete novels. You could pick from among options or propose your own to the teacher. The tests were not questions but you had to instead write a 2-3 page summary of the book including a short review, and then briefly present it to the class. Since most pupils read separate books, I think the concept was different from the US concept where I assume there were then discussions about the books in class?

I remember reading Catch-22 and Crime and Punishment this way. Crime and Punishment was a chore but I rather enjoyed Catch-22.

I don't bother with romance novels (they're usually about abusers being rewarded for being abusers, and not really my cup of tea even when they aren't), but AI is not great at translation, is terrible at metaphor, and is horrific at writing.

If they're going to use AI for auto-translation, then I think the best thing they can do is pay for the first 30 sessions of therapy needed afterwards.

Over-reliance on an unreliable source is stupid.

Britain has plenty of brilliant minds and is more than capable of building services equal, or superior, to those in the US. It honestly isn't hard - I've worked in the US tech sector and their minds are nowhere near up to scratch. Those that are are overworked, underpaid, and essentially beholden to their employer because the US is a "good ol' boy's club" where executives abuse power and authority on a regular basis. This is not a good way to run a reliable, competent, business.

Hell, give me the seed money and I'll set up an damn cloud provider that can beat the carp out of those in the US. I've been in this business longer than most of the techies working on the US cloud infrastructure but I'm also not blinded by the naive assumptions and political intrigues that have defined the sector thus far.

Submission + - Supercritical CO2 Generators Now In Production 1

cusco writes: https://kdwalmsley.substack.co...

Chinese engineers deployed the world's first commercially viable sCO2 power generators, at a steel mill in Guizhou.

The Supercritical Carbon Dioxide (sCO2) generator converts waste heat into electricity. Compared to traditional steam and thermal systems, the sCO2 design is more than 85% more efficient, and produces 50% more electricity. . .

SCO2 is supercritical carbon dioxide. CO2 that’s maintained in a state above critical temperature and pressure, which is over 31 degrees Celsius and 1070 psi. Once there, CO2 acts both as a liquid and as a gas, and in industrial applications, that becomes very useful. As a gas, there is less resistance, and as a liquid, it provides greater thrust. And, turning CO2 into supercritical CO2 is more energy efficient than turning water into steam. . .

Not everyone is as optimistic. Long article which assumes the Chinese will be sloppy with implementation for some reason.

Experience with hydrogen suggests that expecting seals to remain effectively perfect over many years of continuous high pressure operation is absurdly optimistic, and there is little reason to assume supercritical CO systems will escape a similar long term reality. . .

True, but to be fair, the scientists, engineers, and scholars are largely fleeing the country, the tech industry is in a massive slump (agriculture is the only sector growing jobs according to the last reliable official figures), and there's a political need to create the impression that the country isn't in a bad way.

They strive to build The Everyman, but fail at the core mission more often that we'd like.

But... shouldn't they? I graduated from college in 2002. Today I run software development teams that build cloud hosted machine learning models pretty much none of which was a thing in 2002. Even if we want to imagine that college is essentially a trade school but with ivy and columns, the fact remains that your average college graduate's degree far outlives the value of most of what they're taught unless they're majoring in history.

We certainly want people to exit college with the skills they need to either enter the workforce or grad school, but those skills could be aquired for a whole heck of a lot less time and money than a four-year-degree. The college degree is about critical thinking skills; managing complexity; proving a capability for self education and improvement; etc. Or it should be, anyway.

Submission + - China's "artificial sun" just broke a fusion limit scientists thought was unbrea (sciencedaily.com)

alternative_right writes: Researchers using China’s “artificial sun” fusion reactor have broken through a long-standing density barrier in fusion plasma. The experiment confirmed that plasma can remain stable even at extreme densities if its interaction with the reactor walls is carefully controlled. This finding removes a major obstacle that has slowed progress toward fusion ignition.
