Out of the closet. Compelling video on their website.
Thanks for the link, always in your debt.

Here is a new TAE paper presented at this years Fusion Power Associates meeting:

Overall, it looks like they are having some successes.

What’s the Big Idea? A venture capitalist takes on fusion energy by Ray Rothrock is an interesting article on Tri Alpha Energy published in Issues in Science and Technology at .

Nice article on venture capital. I thought the salient point was at the end where the author characterized the development cost, risk, and time horizon to a pharmaceutical drug development cycle. However, the fusion physics is outside of the normal VC science comfort zone and that is perhaps where fusion hits a snag with the VC people? The other point buried earlier in the article was very early on in the VC start up phase where some researcher 'proved' the central idea would not work. Sound familiar?

Seems like Tri Alpha increased confinement times to 11.5 ms and now has funding all the way to a prototype reactor in 2020ies. Not too soon, but not that far away anymore either:

If Polywell is so good, where is the funding?

The confinement time for Tri Alpha was limited only by the neutral beam injection, or in other words, confinement is solved. The goal now is increasing plasma temperature. Then, going to PB.

General Fusion's issue now is adiabatic compression.

EMC2 issue is cash containment.

If I remember correctly, Tri Alpha roughly achieved 1keV plasma temperature so far. Pulsed FRC devices like some of Helion's prototypes have routinely achieved over 5 keV. So it seems relatively plausible that Tri Alpha will achieve the temperatures, they need. What worries me a bit, is that their device is not exactly small anymore and if they get any larger, they will be competing with ITER for scale ;)
Granted, Tri Alpha is aiming for PB11 which is a lot harder. So the comparison to a D+T- tokamak is not entirely fair.

To error is human... and I'm very human.

Reactor size is not what is being increased, the neutral beam injectors need to be made more powerful and need to be continuous duty.

It would be nice to get the details, I think I have seen a presentation where this was discussed. Anyone?

For some reason, I missed this video they posted on their youtube channel 6 months ago:

I sincerely hope that EMC2, Tri-Alpha, Sorlox, Helion/MSNW, General Fusion and other left-coast fusion labs continually archive their latest results in a safe area, in preparation for slippages of the Cascadia Subduction Zone and San Andreas Fault.

Tri Alpha Energy also gave a talk at the US-Japan Compact Toroid Workshop 2016 . Erik Trask gave the overview talk on their progress and upgrade plans. There were three more TAE talks at the conference.
