Comment on China’s ‘artificial sun’ breaks nuclear fusion limit thought to be impossible
AA5B@lemmy.world 1 day ago
I really hate how so many of these articles feel like they need to dumb it down with this “artificial sun” imagery. It feels so condescending. I’d rather learn more about the latest progress with nuclear fusion

So we hear. But the world is not America and this is a British newspaper.

article didn’t say anything. How does denser plasma achieve higher temperatures or other benefits? What advances did their denser plasma produce?
Mpatch@lemmy.world 13 hours ago
Plasma is made from basicly over charging a gas with electrons the gas getting all pissy about having those electrons and starts dumping them. something do with elements wanting stability. In that process you get alot of heat out put. Now f you make it more dense I would conclude simply, you now have more ionized atoms in the plasma stream, meaning your plasma will be hotter if the stream will be the same size or if the plasma stream is shrunk but has the same number of ionized gas atoms, you have the same heat out put but in a smaller stream.

You’re having a space characters infestation, you should do something about that.

Right. where’s the actual content, the wording not treating us like idiots?

There is no current actual improvement other than the possibilities. By cooling the plasma edge and using clean wall materials, they broke a theoretical density barrier that could potentially bring steady-state fusion closer to reality.
That’s all it is. We’re no closer to steady fusion, but now we know we can push past the Greenwald limit.

Thanks. Seems like a positive step

While a plasma is far from an ideal gas:
pV=nRT
p is the pressure, T the temperature, when you increase the pressure while keeping everything else the same, you increase the temperature aswell. The density here is the colloquial term for pressure.

I generally agree that science reporting treats everyone like children, but I really don’t have a problem with this analogy. Stars are the only naturally occurring fusion we have to observe and compare it to. To me that makes sense.
adespoton@lemmy.ca 23 hours ago
Sure… but the metaphor glosses over the fact that they haven’t really told us anything of interest. It SOUNDS good, but there’s no way to tell how significant it actually is.
Fusion breakthroughs have sounded good since the 90s, but we’re still 10 years away from anything useful.

articles such as this one usually are optimized for their audience, you just aren’t the audience. that’s ok. I’m rarely the audience either :) a quick search should give you what you’re looking for www.science.org/doi/10.1126/sciadv.adz3040

It isnt optimized. Its gibberish written just to give some weight to the headline. People do bad jobs at science popularization too.

Cool, thanks. So much more readable
