Guess Next Big Future picked up on my earlier post here and added some new, extra information. We finally get to see a picture of their new prototype!

Skipjack,
Any confirmation that Helion Fusion is going for $35 million series B funding, and any details on who is the broker?

Switches. There are now high current FETs rated at 4.5Kv And that number goes up about 50% every few years. At some point we will get the switches needed.

General Fusion has the best solution to containing the 14 MeV neutrons from the D-T reaction and breeding tritium, but I'm not so sure how well Helion Energy will be able to contain the neutrons and generate tritium. I agree that having a separate burn chamber eases the maintenance of it, but it could require costly remote operations as has been foreseen on ITER. Neither the acoustic compression by General Fusion nor the magnetic compression by Helion Energy has yet demonstrated break even. The different fusion concepts have different advantages and difficulties, but they all have to first demonstrate scientific break even and then technological feasibility. In this sense I think that they all have equal amounts of work remaining, including Helion Energy.

@Skipjack: holy patience you had arguing with the troll at NBF.

Here is another cool article about Helion that I had not seen yet. Some great, new information there. It looks like their updated design is even more promising.
From what I understand they have now updated their design to a sort of D+D - D+T hybrid, which drastically reduces the need for tritium breeding and makes the neutron shielding of the burn chamber a lot easier. It seems like they will be using a FLiBe molten salt for that.
Also wonder how well their design lends itself to a catalyzed DD fusion type approach, where they remove the tritium between pulses and let it decay to He3 for fueling the plant (improving output over DD).
Once again the guys at Helion show how an elegant design can side step the problems associated with neutronic fusion instead of battling them head on (like ITER does) or insisting on a aneutronic fusion.
