France has just sustained a fusion reaction for more than 22 minutes, breaking China's record (from few weeks ago) of 18 minutes.
There’s a revolution happening right now. This breakthrough is massive — and the world needs to know. We’re on the brink of nearly free, limitless energy, the very foundation that drives technological and scientific advancement.
This leap forward demonstrates how our knowledge of plasmas and technological control of them over longer periods is becoming more mature.

This is interesting how China is getting ahead in innovations. The artifical sun isn't a copy.

I think we need more data than just time. What’s most important about fusion is getting more energy out than you put in.

We want more energy out of it than it costs energy to start it up, that's true. If it runs 24/7 one day we will get more energy out of it than we put in.

Maybe need to look at the thermodynamics. Time while important isn’t telling the entire story

Maybe need to look at the thermodynamics.
You're very smug while seemingly knowing little about the topic. There is no issue with the fundamental laws of thermodynamics. If there was, the sun couldn't exist.

I didn’t say anything about the laws. I said just mentioning time is misleading. Biggest issue with fusion is the amount of start up energy needed to get it started and to keep it cold is enormous that is why it’s been fleeting humanity’s grasp for decades

I think you guys are talking past each other. You're both right.
Up-time is meaningless if almost no energy is being produced.
But I think @zuspotirko 's point is that, even if the energy output is tiny, if it can be sustained 24/7 we have unlimited energy. This is true no matter how small the output number is.
It's like the concept of limits in calculus. When something is approaching infinity, it may as well just be considered infinity for all intents and purposes.

Damn, a future complete with tokamak power generation seemed so far off when playing SimCity 2000 as a kid. I had no idea the state of the art of was this far along. I guess there's no mention of the Q ratio here, or how much power was generated, so maybe I shouldn't get too excited yet. Still, just maintaining confinement without melting the reactor within seconds is an incredible feat of engineering.

Dang. Difficulty adjustment to the moon!!!!
Where we're going, we're going to need more zeros (in the hash).

(but on a more serious note: hardware will be a constraint and mooaar power isn't necessarily post-scarcity power)

How much has it cost to make that record?
