Any announcements like this coming from China should be taken with a huge grain of salt the size of... China.

Yep. They‘re putting out what they call huge breakthroughs on a weekly basis for months and make headlines. By the time they have been put into perspective or straight out debunked and torn to shreds by the global scientific community, they already squeezed out another wild claim to overshadow criticism. Rinse and repeat. There is a reason the overwhelming majority of AI generated slob studies come from China. They want fast results and know the press won‘t really read them and instead just quote whatever they claim.

What we need to do is find some way to make a giant fusion reactor and put it in the sky and get energy from it that way.
But that's just a pipe dream...
What we need is robust decentralized multimodal energy production fit for the local area where it is installed and contributing to a well maintained distributed grid with multiple redundancies and sufficient storage so that incidental costs are minimized and uptime is effectively 100%. Energy is a tool and its generation is a category of tools, whining about people developing a better screwdriver rather than only using hammers is counterproductive when we're trying to build a house for as many people as possible that doesn't fucking kill everyone.

Yeah, and then that artificial sun can give us power at night
It's too bad there isn't some sort of way we could store electricity in some sort of containment.
Then we could do stuff like take electrically-powered devices with us wherever we went! Think of how handy that would be!
Yeah! We could use such technology to trap this "artificial sun" instead, and then have a steady stable output throughout the night for things that use a bunch of electricity but run constantly, like water filtration plants and material processing facilities.
Great idea! But I guess more research is needed to make this work for the things that use the MOST electricity, instead of small portable devices that use a fraction of the electricity

Impressive. :)
I'm tempted, but won't try to guess how operation endurances will progress - it would be an poorly informed guess by a rando. Better to wait what they write about it in journals.

Not a word about how much energy went into the process and how much was harvested…
I can create plasma using a candle and a microwave.

A 17 minute runtime in a Tokamak an incremental step on the path to success. You're in the kitchen looking over the shoulder of the chef saying the steak he's just put in the pan isn't cooked enough yet. He knows, but you can't have the steak on your plate cooked to perfection until he does this current step he's on.

In 1964 you could build an honest to goodness fusion reactor copying the Farnsworth Fusor, yet that would never be on a path to a sustained fusion reaction with a net energy gain. The work in the article is.
Producing energy is not the goal of this facility which is why they don't report on it. The useful output is in refining control and heating methods so that when power producing facilities are built, they can operate continuously. On that front, 17 minutes is very impressive. At the speeds at which the particles in a fusion plasma move, that time frame is essentially an eternity.

Great. Now put a magnifying glass in front of it and point it at the white house
So what are the limitations of running the reactor for longer? Is it containing the plasma becoming infeasible due to heat or other constraints or does the reaction inside the plasma fizzle out?
