Lockheed's compact fusion reactor question

Click For Summary
Magnetic mirrors were initially considered for fusion power but were found to allow plasma escape, leading to doubts about their viability. Lockheed's new model incorporates cusp confinement, which aims to address some of these issues by creating denser field lines, yet concerns remain about plasma leakage through open field lines. Critics argue that without significant innovations beyond the cusp and mirror concepts, Lockheed's design may not improve upon previous attempts. Historical context reveals that the mirror program was cut due to budget constraints rather than a definitive failure of the concept. Overall, skepticism persists regarding the effectiveness and potential advancements of Lockheed's approach to fusion technology.

If it was possible to produce enough ultracooled material in the Bose-Einstein condensate state,
that might help to reduce the size of some reactor parameters.
The trouble with that is you probably need a massive and dangerous industrial plant to make enough of it.
Where do you expect Bose-Einstein condensates to be useful, and where do you see a danger from them?

It is the kind of summary that reflects real work done by serious and dedicated researchers, stuff that is rarely seen any more.
Every publication, every conference, every other meeting has that.

Quenches are a necessary part of the commissioning - you need them to improve the maximal field strength of coils.

I don't the field strength Lockheed wants to use.

It is good that these summaries are produced. What is missing is wider dissemination of the results.
I do routinely skim the various journals such as Science News or Technology Review, there has not been such a document referenced, much less actually linked.
It is as if the field were operating under a security blanket or the leaders were ashamed of what they were doing. There is no effort to celebrate gains or to create some sense of the potential. Given that fusion seems a lot greener than covering the Earth with windmills and solar panels, that reticence is incomprehensible to me.

I'll try dig out a reference, but I do know that I read somewhere that Bose-Einstein condensates are a form of matter that can only exist near to absolute zero.
Matter in that state so I gathered can undergo fusion without the need of extreme pressure, (containment).
If that is actually true then you don't need the megawatts of power needed just to get the reactor started up, everything can be downsized.
However the industrial scale production of such material is definitely not feasible with present technology.

I think if that was feasible, the careful handling and application of the resulting material would be risky.
If for some reason there was a problem in transporting it very quickly, could it explosively undergo a phase transition to 'normal' helium or whatever.

That is clear and doesn't need a reference.

Who claims that?
