From what I understand, they do have experimental data and "power in the bank" from their direct conversion method, though the efficiency is currently a well kept secret.

The direct conversion system is intrinsic to Helion's reactor design. The charged particles induce a current in the magnets that drive and compress the plasmoids. Plus they can recoup quite a bit of the energy that went into driving the fusion reaction in the first place. This is why they believe th...

That's one of the reasons why I like Helion. They don't have those problems.
I think CFS has a pretty decent grasp on the divertor issue. At least judging from Dennis Whyte's divertor design class.

Simulations are only as good as the real life data you base them on. We do now have a pretty good amount of practical experience with STs. Not as much as with regular Toks, but not bad.

I don't think that TE will be the first, but they will likely be one of the first. I think they have a good chance to beating MIT/CFS, though CFS has a lot more money. I see them definitely beating TAE and and probably General Fusion too.

I don't see TAE anywhere. I see MIFTI, which is a staged Z- Pinch and PPPL, which is a FRC device. Sadly, the more interesting SFS Z- Pinch from ZAP does not seem to be in the running. Also MSNW's Fusion Driven Rocket could have been interesting to look at. PPPL is still quite a few years away from ...

I agree with that, but it shows that there is a path forward to do this IF engineering challenges can be resolved.
Clearly there is a lower limit to the how small it can get, but it is still better than that ITER monstrosity, likely even better than ARC.

That sounds very encouraging. Seems like Tokamam Energy made the right choice going for a Spherical Tomakak instead of a regular shaped one like Commonwealth does.

I agree on most of the points you are making. That said, they do not have to increase the input current that much get a viable reactor (1.2 MA, I believe) and according to Uri, they have some other "knobs" (rather than just the current) that they can still play with to improve performance. I think t...

Good and fairly recent presentation by Uri Shumlak:

Hmm, interesting.
Could have application in some fusion reactor designs. Question is how efficient those magnets can be.

LOL, it is livescience...
The science in the name has nothing to do with the idiotically shitty content on the website. I got banned from their comment sections because I kept pointing out their BS. I am not even going to bother reading the article.

Glad you are doing well bud! A heart attack is nothing to sneeze at! I did not know you had one. Glad you are OK. Please be careful and take care of your health!

This one will be interesting: https://meetings.aps.org/Meeting/DPP20/Session/CP20.10 Deformation of Plasma-Facing Surfaces in the ZaP-HD Device: Target surfaces are analyzed with a scanning electron microscope and energy-dispersive x-ray spectroscopy.

They might not be mentioning the issue anymore because it turned out to be a non issue. I mean, we will see what happens. From what we know, they are planning to achieve a notional Q~1 within the next 3 years (I read an earlier statement that said 2 years). Until then, we can only speculate. I prefe...
