Hotter than the surface of the sun by a factor of ~18000.

Hotter than the suns core by a factor of ~7.

People talk about Icarus flying too close to the sun. Motherfuckers are recreating it in labs πŸ˜‚

Hotter than yo mama …. Wait a minute

[–] rigatti@lemmy.world 1 points 2 years ago

Just barely though...

If Icarus won't come to the sun, the sun will come to Icarus.

Is… is that good?

Edit: it is!

[–] ummthatguy@lemmy.world 1 points 2 years ago (1 children)

From what absolutely little I know, yes. Sustaining the reaction at such high temps for long is, as of now, difficult.

[–] gregorum@lemm.ee 1 points 2 years ago (1 children)

Yeah, I decided to actually bother and read the article. That’s why I made my edit. This sounds like a very important technical milestone for the development of fusion reactors. Hooray!

[–] assembly@lemmy.world 1 points 2 years ago

48 seconds at those temperatures is no joke, that is pretty amazing. I didn’t see the article elaborate on what the current limiting factors are for pushing beyond 48 seconds. Like I wonder if it’s a hard wall, a new engineering challenge, a tweak needed, etc. this is the reactor that set the last record so they are doing something really right.

Unfortunately the amount of helium made in fusion is so small as to be useless for anything humans need. Fusion is just that efficient.

[–] dohpaz42@lemmy.world 1 points 2 years ago

So no chipmunk voices? 😒

[–] Scrof@sopuli.xyz 1 points 2 years ago

Can't wait for fusion reactors to not be thing for another 50 years at the very least.

100 million degrees C

Sounds hot.

[–] CosmicCleric@lemmy.world 1 points 2 years ago

Sounds hot.

You should see it in a bikini.

[–] Pistcow@lemm.ee 1 points 2 years ago

Almost as hot as the temperature my wife leaves the shower at.

[–] whaleross@lemmy.world 1 points 2 years ago (2 children)

Hot damn! Limitless fusion power is only thirty years away!

[–] hydroptic@sopuli.xyz 1 points 2 years ago

Like it has been for the past 30 years (which, I assume, was the joke here.)

If fusion research was funded adequately we'd probably have it by now, but I don't know if it's the energy lobby or what that means that it's chronically underfunded. An actually working fusion reactor design would bring about such an upheaval in the energy markets that I wouldn't be surprised if plutocrats had a hand in making sure the research receives orders of magnitude less money than it should.

[–] ours@lemmy.world 1 points 2 years ago

Breakthroughs will bring in investment and then things can accelerate if it ends up viable.

[–] FritzGman@lemmy.world 1 points 2 years ago

Soooo, we will all start sounding like Alvin and the Chipmunks soon?

[–] fidodo@lemmy.world 1 points 2 years ago

I'd like to know more. How do you actually harness the energy produced by temperatures that high? Is the end goal to figure out how to sustain the reaction at lower temperatures or do we actually have ways to generate electricity from those temperatures without losing most of it to waste?

[–] Gigan@lemmy.world 1 points 2 years ago (1 children)

I'd love to see an operating fusion reactor in my lifetime. Real sci-fi technology

[–] virku@lemmy.world 1 points 2 years ago

Currently reading news and communicating with people around the world from the privacy of my toilet using my hand terminal. It can also understand what I am saying and excecute my spoken commands (to some extent at least). That's some Sci fi shit right there. Pun intended

[–] phoneymouse@lemmy.world 1 points 2 years ago (1 children)

Can’t be good for our global warming problem, amirite?

[–] iceonfire1@feddit.nl 0 points 2 years ago (1 children)

Lol ironic isn't it, considering easy access to fusion power would basically solve the climate crisis.

[–] SatansMaggotyCumFart@lemmy.world 0 points 2 years ago (1 children)

If you had a bunch of fusion plants running AC units could you reverse global warming?

[–] snugglesthefalse@sh.itjust.works 1 points 2 years ago (1 children)

Ignoring actual practicality.... I guess you could run a heat exchanger and dump all the energy into a tiny object then shoot it into space

[–] LodeMike@lemmy.today 1 points 1 year ago

Not the timezones!

[–] FireTower@lemmy.world 0 points 2 years ago (1 children)

One step closer to getting the T-51s working.

[–] n3m37h@lemmy.dbzer0.com 0 points 2 years ago (1 children)

Only 2,543,456,495,596 steps to go

[–] LodeMike@lemmy.today 1 points 1 year ago (1 children)

This ia a reference to max signed int32 right?

[–] n3m37h@lemmy.dbzer0.com 1 points 1 year ago (1 children)

No, the fact the technology has been 5 years away since the 80's
