Edits could be proposed for the Wikipedia page...

Indeed, but I have no idea how the procedure works.
If someone knows how to do it than changes should be done as that section is highly misleading.

The direct conversion unit is still totally theoretical until now, so I would not dismiss it as a "solved issue", and this includes also the re-circulation of the injected power.
Selling Tritium could indeed be a good source of income for pushing the financing of additional research funds.

I went to quickly read it back to refresh my memory. Here is the paper for everyone to read: https://ses.library.usyd.edu.au/bitstream/handle/2123/21070/bowden-reid_rd_thesis.pdf?sequence=1&isAllowed=y The Apparatus description and experimental runs start from page 53 And here is a passage of the la...

If it's the final nail in the coffin for the Polywell, is it also the final nail for Lockheed Martins experiment, they have a lot in common. Did the paper also look at the results from the last EMC2 WB-X device? The test apparatus of the paper was just two magnetic coil rings parallel to each other...

I would say no. The experimental apparatus is different from a Polywell machine and the power and energy configurations are also order of magnitude smaller. The conclusions and explanation on why he didn't measure a potential well with this apparatus are indeed interesting. Interesting also the deri...

Indeed Helion does not have to bother with divertors, but the trade off is that they need to develop a proper direct conversion energy system that is probably on the same level of engineering difficulty. But I think that their main problem will be to develop the 3He generation process (from the D-D ...

My personal bet is that the first one that will solve "Divertor" and "First wall" engineering issues will be the winner.

Yes, most of the models I saw have the tendency to have too many assumptions (mostly to reduce the computing power needed to run the simulation), but this in the end prevents to have a clear understanding of the equilibrium point of the interactions among the different forces, especially for what it...

If after all what happened in the last 20 years they are still able to find people willing to invest in their magical technology, than I can only say that those people deserve to part ways with their money...

Nice video indeed.
It will be be darn interesting to see the results of the 20 Tesla magnet on that DEMO4 test machine. If it follows the theoretical prediction than ST-F1 machine might indeed be the first fusion reactor of humanity.

Better performance is always benificial. One way or the other.

Absolutely true.
I was just pointing out that those are not data from a real machine for now but just the results of a numerical simulation, with all the limits and pitfalls of simulations.

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. Of course I fully agree. My concerns are mai...

"We find that for similar values of field and fusion power, but smaller volume, STs can have nTτΕ up to a factor of three higher and Qfus an order of magnitude higher than CTs." "Potentially our results open an alternative and faster route to fusion power based on relatively small, low power STs." ...

Yes, input current needs can eventually be managed if they are able to reduce the radius of the pinch, so the MHD instabilities will be the beast to tame. I am also very happy to hear that they have enough funds to move on the research to clarify if they can make it feasible. Let's wait and see what...

Good and fairly recent presentation by Uri Shumlak: https://drive.google.com/file/d/1nHKEa_Bxh4d_JhWo7F6vJR69A5FQFmFX/view Thanks, it was a very interesting video. There is lot of new info that I didn't know into this presentation, it helped to clear some doubts I had, but it strengthened some othe...
