TAE Technologies has published another paper and announced a very interesting research partnership with Japan´s National Institute for Fusion Science on testing pB11 in the Large Helical Device (LHD) stellarator:

Simulation of equilibrium and transport in advanced FRCS, https://iopscience.iop.org/article/10.1 ... 326/ac1e5f

For more details on the public-private partnership see this press release: https://tae.com/tae-technologies-partne ... -research/.

I am not sure TAE is going to be relevant by the time they do their thing...

Nevertheless, they are doing solid work. I would suggest that neutral beam injection would overcome any instabilities that Zap Energy encounters that they cannot solve.

Not sure how neutral beam injection would apply to a Sheared Flow Stabilized Z- Pinch, or any pulsed fusion device for that matter.

Plasma physics modeling is done in hindsight, so using it for predictions over multiple orders of magnitude is a crap shoot. After reading Zap's paper on modeling and the two instability modes, second being the kink mode, I realized that no one really knows until you build it and test it. Whether or not anything will help deal with an instability is sheer wild speculation, so yes, how neutral beam would help or not is just BS'ing.

We can say though what has been tested works which goes for Helion, General Fusion, and TAE. Zap is not there yet (as far as I know), soon they will know, but their scaling is the 11th power and they have some wicked instabilities to deal with.

True that. I hope we will know in 18 months from now, whether they made it or not ;)

TAE Technology has published a 90 s video on the history of their experimental devices in connection with the blog post on the appearance of TAE Technology in the film "Finch".

2021 Fusion Power Associates Meeting slides:

Maybe noteworthy is the 5 keV ion temperature with an electron temperature up to 1 keV.
I am not sure they have previously reported that high temperatures, but I might be remembering things wrong. High ion to electron temperature ratio is certainly good to have as it will make PB11 easier for them.

Copernicus production has already started with first commissioning set for late 2023.
"Hydrogen only operation". If that means "protium only", then it is a bit disappointing and it would contradict earlier plans for D-T fusion demonstration.
It would require another machine to demonstrate a viable D-T power plant.
So I am not sure how to interpret all that.

Copernicus with current budget is targeting goals that only support development of their next machine DaVinci, however Copernicus is able to perform testing for D-T (with more money).

Face it, Helion will be selling commercial machines and generating revenue from power generation before DaVinci is built and tested.

I think that Helion will be the first to put power on the grid.
ZAP might be the only team that currently has funded (!) plans that are close with them going for Q(sci)>1 in 2023 and Q(eng) >1 in 2026.
TAE is going for Q(sci) > 1 in 2024/2025 (though from the looks of it with protium only and then extrapolated).
IIRC, DaVinci is planned for 2028 unless plans have changed.
The plans by all the others are lagging behind these three at least a little.

Zap's aggressive parallel paths would infer confidence that they will not run into hidden stability problems. They do have modeling that supports that.

Bombshells will go off with Helion and Zap successes.
