Meanwhile USA is stealing Venezuelan oil. Good job everbody. 👍

Just a few years ago US labs were the first to generate more power than they put into a fusion reactor, it was one of the most important breakthroughs to date in fusion.

Even under the shitheap Trump, the US is continuing to research into fusion and building stellarators such as Infinity 1 in Tennessee.

Europe likewise is leading breakthroughs such as with Wendelstein 7-X stellarator in Germany lasting for 43 seconds. This is being improved with the new Proxima Alpha stellarator being built.

China’s EAST reactor had a breakthrough when they achieved 1,000 seconds last year. While Europes recent ITER tokamak should be achieving its first plasma in the coming years.

Fusion is a global effort, and scientists are benefiting from the works being put in elsewhere. Stellarators and Tokamak are both breaking new grounds each year, and each has their own pros and cons.

Don’t fall for any propaganda trying to claim anyone is “winning”.

What ? It was not really. Here's a physicist discussing why.

https://dothemath.ucsd.edu/2023/08/fusion-foolery/

In the end, the NIF fusion accomplishment might be called a stunt. Stunts explore what we can do (often after an insane amount of preparation, practice, and failure), rather than what’s practical. Stunts hide the pains and present an appearance of ease and grace, but it’s a show.

The “more energy out than laser energy in” equation masks several fundamental problems. NIF’s doped glass lasers have an efficiency of about 0.5 percent, meaning that they would have sucked in roughly 400 megajoules of energy from the grid in order to produce the 2.1 megajoules of light energy…

To be fair the hype machine was from the press not the scientists

Let’s pause to say: well done! Honestly. No sarcasm. What they did was ridiculously hard, and it finally worked after more than a decade of trying. They actually produced a significant number of fusion events! There’s no faking that, and I’d like to see you try. So let’s be clear that I’m not knocking the accomplishment in itself. My major beef is how we interpret the implications for society.

Stunts also draw attention to stuff. Its yet to be seen if its a net positive but it did help me get up to speed on the current state of fusion technology.

These comment sections can be a place of puerility and defeatism. Thanks for being the difference.

While we maybe researching and contributing into Fusion we are not at all looking into making use for the energy grid. At most just if it can be used for the Data Centers

(Which is yes we could but I think providing free energy for homes is a better use you ask me.)

Thanks for your positive and refreshing comment ❤️

I'm assuming the sole reason the Orange cunt hasn't destroyed the US's fusion research is because he wants to give exclusive rights to build and use it to ~~Vault-Tech~~ the tech broligarchs who bribe him.

[–] SaveTheTuaHawk@lemmy.ca -2 points 2 days ago (1 children)

It's still decades to never from being practical.

[–] Deceptichum@quokk.au 17 points 2 days ago

It always will be until the day it isn't. Breakthrough's cannot be timelined or predicted.

Well. At least it will guarantee the USA's eventual fall from power.

Can you imagine the tech bros and anti-intectuals groveling to rejoin the scientific community?

Unfortunately science is not a morality structure.

Stay positive buddy.stay positive buddy, if oil become obsolete the struggle of the us will end. Their trouble is price of oil. They need to inject oil in the system to reduce price and stay competitive with solar, etc. And they have to attack other country to maintain the system. It stay viable for long they will have to go renewables.
