Yeah I get that but no one has apparently managed it up until this point.Yawn. We’ve been here every 12 months for the last two decades. I mean I hope it’s true but this claim is next level crying wolf at this point.

No we haven't been here before. That's the point.Yawn. We’ve been here every 12 months for the last two decades. I mean I hope it’s true but this claim is next level crying wolf at this point.
Where we have been for decades are scientists claiming that they have reached net energy output with fusion. If these guys/gals have done it, then that's phenomenal.No we haven't been here before. That's the point.
It's definitely great news for rare forms of cancers, I kind of feel we're at the tipping point of major breakthroughs now with biotech and the likes of CRISPRBase editing: Revolutionary therapy clears girl's incurable cancer

There's always been theorised approaches, but often getting funding is very hard.Where we have been for decades are scientists claiming that they have reached net energy output with fusion. If these guys/gals have done it, then that's phenomenal.

Isn't it! Just amazing!Some of the stuff humans can do is just incredible.
The thing is with this kind of research though is once a breakthrough happens and it yields results other people can focus on making it viable too.Tweet

Seems to be backed up a bit more than previous ones. Still a way to go though.
Also Val Kilmer that poor bastard.
To me, the biggest thing I take from this is that it at last proves that the process of positive output Nuclear Fusion is possible. Yes we knew that it should be possible. But for the first time, it has been proven. And proven by a reasonable margin.This seems to be a bit different to the previous breakthrough. To be fair, every previous breakthrough looked like it could be the one, but this really seems to be the one. First time ever it reaches parity, in fact, it produces 20% more energy than it needs.
Always thought that if there is a solution for the climate change, it is going to be technological. I hope this proves correct and in a couple of decades, the world has moved from fossil energy (or more likely, it has become carbon neutral).
They can try all they want, it won’t stop the civilised world working on it where they have zero influence.Can’t wait until the GOP demonise this and all progress comes to a crawl.
My wife is about as a pessimstic as it gets about climate change, and she sees this is as something super positive that might really turn things around once it becomes practically operable in, say, 30 years.EDIT. The world needed a piece of good news and this certainly seems good news.
As the old saying says, fusion energy is always 20 years in the future, no matter what year are you reading this

You are discounting the oil and coal industries pumping in millions, to both sides.It's certainly an accounting win, I'm not entirely convinced by it given that they didn't factor in the losses in the lasers so it didn't actually produce any net power. Perhaps the control of the plasma is the real achievement here I don't know, but it seems like a very technical win.
Oh and for the people thinking the GOP will be against this, it's very unlikely I think. The technology will be big, centralised and profits privatised. Right up their street I would think compared to solar or wind power which is much more simple technology and can be deployed in a more democratic manner.
They'll be investing in it I should think.You are discounting the oil and coal industries pumping in millions, to both sides.
Yes. But on this occasion, it really might well be just 20 years away.As the old saying says, fusion energy is always 20 years in the future, no matter what year are you reading this

This was just one experiment among a number of experiments. Effectively a proof of concept. And the result was that the concept was proven.This is really exciting news.
One thing i have read though is that "it will take decades to make this commercialy viable". What does that mean really? Does it mean its challenging to build on a large scale because of the technological infrastructure or does it simply mean its so expensive its not profitable?
Exactly that.I'm working through my understanding of this. The breakthrough was that they put in ~2MJ of energy to the target and generated ~2.5MJ of fusion energy output. "It's the first time an experiment resulted in a meaningful gain of energy."
But, "the positive energy gain reported ignores the 500MJ of energy that was put into the lasers themselves."
So powering up the lasers took 500MJ, then the lasers pointed 2MJ at the target which generated 2.5MJ of energy? So they'd need to sustain and/or scale up the reaction to "repay" the cost of the laser energy, and even more so to actually produce net energy? Presumably they can use the energy from the reaction itself to sustain and scale up and that's possible because they achieved "ignition"?
It's an incredible achievement, to harness the power of the stars themselves.
Thank you very muchThis was just one experiment among a number of experiments. Effectively a proof of concept. And the result was that the concept was proven.
But it is very important to understand that a huge amount of data was needed to determine how much energy was put in and the net amount that was output.
But importantly, it was a scientific experiment.
There are a number of other programmes underway around the world using differing methods to this one to create the right conditions to force 2 positively charged Hydrogen Protons to overcome the repulsive electromagnetic force to be held together by the strong nuclear force such that a heavier Helium (3) atom is created. The tiny amount of mass that is given off results in the energy output. This requires incredibly high temperatures and pressures.
To create a commercially viable nuclear fusion power station, those incredibly high temperatures and pressures need to be sustained for very long periods of time. Not just a few fractions of a second.
That is the biggest challenge which has yet to be developed.

Im not diminishing what they accomplished. Im sure is a big leap, and is an incredible feat but there are so many other factors, materials, how to sustain plasma floating permanently (i mean, the current tresshold is counted in mimuts and seconds) and so onYes. But on this occasion, it really might well be just 20 years away.
By which time I could be 92 if I am still alive then.Im not diminishing what they accomplished.

To be honest, im quite certain that i ill not see fusion energy at commercial level and im 42
I can only say, see you in 20 years
But that's how magnetic confinement works, right, not inertial confinement? I could be hopelessly wrong...Im not diminishing what they accomplished.
