Not entirely clear if that's Polaris or the power plant. If it's the plant at 50MW it doesn't work at 1 Hz: the capacitor bank will be empty after supplying the grid when the next shot cues up. At 2 Hz, I don't think it can work at a Q of 2, because of losses. A consistent picture at 3 Hz would be ...

SJ, any idea what the new earthwork is all about at Helion's new plant? Accelerating production plans??

Been trying to get information on that.

No, I don’t think so. If its producing a net 5MJ in each pulse, and doing one pulse per second, thats 5MW: a Watt is a Joule per second. What is strange is that the core seems to be idle something over 99.7% of the time. Seems like an opportunity…though I dimly recall 10Hz as the target for the com...

happy if they managed to power a light bulb. Yes. That was the context for Polaris power production, just to reach net electric, not commercial. I thought that was understood. Hence the capacitor sizing for polaris is just to form the plasma, accelerate, then compress it, then recover it minus loss...

HERT: So 1Hz, circa 50 MJ in, say 55 MJ out, is 5MW. yes but unfortunately it's only 5MW for 1ms, which is not very useful, practically speaking, as it would only provide 5KW over the 1 second, or enough to power an average home (although again I have to emphasize this is still 50 years ahead of ma...

This does confirm that the final assembly of Polaris has shifted to the right by a few months and is now scheduled for summer.

(theoretically Q-eng>1 should be possible even with Q-sci<1) at one point I also thought this might be true, but then I decided it can't be because then there's nowhere for the losses to come from (as per above) i.e., if per Kirtley's graph you have to spend 10MW in losses to get 50MW in output, th...

pulse length in Polaris is somewhere around 1 ms Plasma duration at point of compression in the device center is one time, which I suspect SJ is saying is ~1ms, then there is the magnetic field sequential firing to accelerate the plasma from each end to collide & to be further compressed, and that ...

From what I understand, pulse length in Polaris is somewhere around 1 ms, give or take a few hundred microseconds. They can not make it much longer for the reasons outlined by Charliem. Again, as mentioned, Helion would rather terminate the pulse early and recover the energy than keep the plasma ali...

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...

Second those hopes...

Ah! I remember them as Princeton Stellarators. Good call!

New newsletter out today. Welp, they broke their electrode again... It will be at least March until they have a replacement. I predict that we won't see them having any significant progress until mid 2024, maybe even the end of 2024... or 2025... https://www.lppfusion.com/storage/LPPFusion-Report-De...

New Helion news letter is out. It is quite long, so I can't post screenshots. Link to web- version: https://mailchi.mp/helionenergy/recapping-2023?e=fb0f77adc2 Team is now 220 people strong. They are currently upgrading the Polaris formation test section after results from the initial tests. A major...
