Re: Helion Energy to demonstrate net electricity production by 2024
Making some reasonable assumptions about Polaris dimensions, an accepting particle densities similar to those achieved with previous generations, I obtain that Polaris' tau(n) ~ 2.5 ms... So, 1 ms of fusion per second for Polaris thanks charlie, that sounds plausible to me For starters, Bremsstrahl...

Re: Helion Energy to demonstrate net electricity production by 2024
thanks mvan and charlie, I am a bit more interested in the compressed (fusing) plasma lifetime (since that's when power is produced), but the total pulse length might help us estimate utilization factor (the proportion of time that a reactor can spend producing power) which could then give us an ide...

Re: Helion Energy to demonstrate net electricity production by 2024
yes, instantaneous conversions are confusing... you have to mix energy (joules sitting in the capacitors pre-pulse) with power (watts flowing into the Polaris system to do various pulse-related things such as compress or accelerate the plasma (essentially transferring the energy), then flowing back ...

Re: Helion Energy to demonstrate net electricity production by 2024
thanks Skip, much appreciated been looking over Kirtley's paper, this seems to be the crux https://media.springernature.com/full/springer-static/image/art%3A10.1007%2Fs10894-023-00367-7/MediaObjects/10894_2023_367_Fig15_HTML.png so if that's accurate they expect usable power to be about 3x combined ...

Re: Helion Energy to demonstrate net electricity production by 2024
Well rail and road. Rail only gets you so far... depends what you're doing, heavy industry has traditionally been located along rivers and railroads for that very reason not unusual to find coal power plants with dedicated tracks the last mile problem has been around forever of course they probably...

Re: Helion Energy to demonstrate net electricity production by 2024
Sure, you can, but they won't fit through underpasses, you need special permits, it slows things down tremendously. Helion wants to produce (eventually) 20 machines a day. That is a lot of machines to transport. Tactics wins a battle, logistics wins the war. yes Kirtley says in the last video they ...

Re: Helion Energy to demonstrate net electricity production by 2024
Helion's magnets are just standard aluminum magnets. Not super conducting. I can't unfortunately give more details in their past magnet experiments. The alternative to stronger magnets are bigger machines. From what I understand, there is currently no noticeable limit for how big you can make them ...

Re: Helion Energy to demonstrate net electricity production by 2024
hmm otoh their machine is pulsed and I see LANL has achieved 100T(!) in a pulsed magnet, though apparently not SC and I'm not sure for how long so now I'm not really sure how hard 30T would be for FRC reactors Helion's probably thought about this a lot more than I have though, maybe they'll share so...

Re: Helion Energy to demonstrate net electricity production by 2024
fwiw Skipjack, agree it will be technically difficult to achieve 30T, suspect they are hoping Polaris results keep them under 20T for the next model 20T still seems to be practical maximum for SC magnets, but even at that size you'd have to worry about flux creep larger than that and you're trying t...

Re: Helion Energy to demonstrate net electricity production by 2024
the final magnet size would depend on a number of factors, they probably want to keep that as small as possible given how it drives final cost Trenta was 8T, and Polaris is 15T, so 30T is probably a reasonable guess for the first demonstrator plant ideally we'd see a commercial reactor eventually wo...

Re: LENR Is Real
parallel -- Thanks for keeping up on this in the face of a lot of negativity. Have you seen anything suggesting smaller units might be available soon? I worry that with the larger units Rossi may be at a price point where legitimate questions of reliability and controversy will prevent much success ...

Admit it, we all laughed when the MFMP device blew up on a live feed. It was funny. Well, it would have been less funny without the shield. http://energycatalyzer3.com/news/e-cat-replication-attempt-ends-in-explosion It's interesting we never heard back from Ahern. Oh wait, uh oh...

Re: EMC2 has published a polywell preprint on arXiv
Not that exciting, we already knew wiffleball confinement is a real thing, but nice to finally see this published.
It's interesting they talk about a reactor with 250MW input and 2GW output. That's a pretty hefty machine! I wonder what loss scaling assumptions went into that.
