Re: KSTAR - South Korea's magnetic fusion device

The news appears to be that KSTAR "broke its own record". You might think that meant it held the previous record, and that ought to be a reasonable assumption.

Lawyers, politicians, and headline writers.

Re: Chinese Scientists Say They’ve Discovered Cheap New Way to Do Nuclear Fusion

From the referenced SCMP article:
Lead researcher Zhang Zhe predicts a new generation of large-scale laser facilities will be finished or near completion in China by 2026.

Re: Z-Pinch Renaissance

These efforts aim to scale the pinch current, plasma density, and plasma temperature to reach scientific breakeven equivalent conditions by early 2023 in the next generation device FuZE-Q, which is currently being commissioned. I'm guessing this means that they expect to achieve conditions with DD ...

LLNL "at threshold of fusion ignition"

LLNL has announced that on August 8 the National Ignition Facility achieved a fusion yield of more than 1.3 megajoules. This is not quite ignition, but it is getting there. Omar Hurricane is quoted as saying, "To me, this is a Wright Brothers moment," which is what's making the headlines , but he al...

Dr. Jaeyoung Park is a co-author of the paper, and his affiliation is given as "TAE Technologies, Inc." When did that happen?

Re: Lawaranceville E-Newsletter

Also, with lower Z brehmstralung should be lower, so the plasma would heat up faster, other things equal. That could be a compelling reason to test with D+He3. My understanding is that Bremsstrahlung is supposed to be minimized by the quantum magnetic field effect, but LPPFusion hasn't yet reached ...

Re: Lawaranceville E-Newsletter

I asked a similar question (though not specifically about He3) a long time ago on the Focus Fusion forums. I forget exactly what the answer is, but my understanding of the fuel situation is this: deuterium (what LPP has been using) is useful mainly for diagnostic purposes because it produces neutron...

Re: 2021 state of the horse race: ITER vs. dark horses

You are stuck in the thinking that these companies are still trying to prove their science. I'm not sure I understand what you're implying. I see perhaps three possibilities: 1) These companies don't have to prove their science to the general public. No doubt this is true for now and until they hav...

Re: Using gravity to create a self sustaining thermonuclear reaction

Interesting. Could this be interpreted as a refinement of the "elephant" idea?

Re: 2021 state of the horse race: ITER vs. dark horses

So, near term: LPPFusion (dense plasma focus) - Experiments planned this year, hopefully starting in May. Possibly hydrogen-boron experiments by late summer. Scientific feasibility possibly demonstrated this year...or not. LPPFusion's small team is slightly larger than when they started experiments ...

Re: The world's worst reactor idea: The OhioVR mantis reactor

It was just a joke, obviously, a throwaway example of a fusion "concept" someone might dream up but never realistically implement. I found the post . The context was Chris's list of fusion technologies, and particularly what sort of concepts should be excluded from the list: Well, I think someone sh...

Re: The world's worst reactor idea: The OhioVR mantis reactor

Sometime, when I find the time, I'll have to flesh out the elephant & deuterium balloon concept. I believe it was ChrisMB's concept initially, but since he didn't bother to do the math and engineering, it's up to someone else to pick up where he left off. Right now I'm weighing the costs and benefit...

Re: Tokamak reactors could be practical with this one weird trick

I think the fact that some other fusion researcher thought of it first shows it's an idea that is (or was) worth trying out. I'd be interested in seeing what the actual experimental results were, and what the rationale was for not pursuing it further. There's a difference between "We already tried t...

2021 state of the horse race: ITER vs. dark horses

The year is 2021. ITER assembly is 70-75% complete. This year begins assembly of the vacuum vessel, with first plasma expected within five years. So far all ITER member nations appear committed to the project, and funding seems secure. Still time for a dark horse to suddenly steal ITER's thunder, bu...
