Re: Tokamak Energy news

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.

Re: Tokamak Energy news

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...

Re: Tokamak Energy news

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.

Re: Spherical Tokamaks

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.

Re: Tokamak Energy news

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.

Re: Trump Promotes Fusion Space-Travel

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 ...

Re: Spherical Tokamaks

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.

Re: Spherical Tokamaks

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.

Re: Z-Pinch Renaissance

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...

Re: Creating a magnetic field at a distance

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

Re: Creating a magnetic field at a distance

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.

Re: Z-Pinch Renaissance

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...
