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.

Looking forward to the controlled landing attempt on the RTFM -- I mean, JRTI.

Re: Mach Effect progress
Hope you're right about getting more data this year, GIThruster. I really hoped 2014 would be the year we saw more replication, a little disappointed on that front. Anyways, I'm sufficiently intrigued by your comments (and his emails to the group) to read Woodward's book (anyways I need some light r...

Re: Aviation Week on the Lockheed Skunkworks CFR
With mechanical supports for the coils, this idea is dead in the water. You cannot get 'recirculation' that way. All the plasma on the field lines that pass outside those 'internal' rings can ExB or grad-B drift around azimuthally until it collides with the stub and is lost. So you basically turn i...

Re: University of Washington dynomak
As best I can tell, just another tokamak/spheromak variant. I wouldn't expect dramatically different results.

They do claim to get high beta.

Re: EMC2 website upgrade in progess
Well, WB-8 was intended to test scaling. It sounds like we learned the wiffleball scales pretty well, but the well depth does not scale quite as well. That sounds like they're seeing more maxwellianization than expected. And apparently they're not even trying to do p-B11. So, presumably the next ste...

Re: EMC2 website upgrade in progess
EMC2 is upgrading their website. The picture has been taken in November 2010, so maybe it is WB-8? Pretty picture, thanks for sharing! Yep, based on the lack of nubs that appears to be WB-8. If we're lucky they're redesigning to announce WB-9. If we're really, really lucky WB-9 is a 100MW prototype...

Re: New Experimental Polywell Publication
why the geometry mistakes of the early machines would be repeated. Bussard's results are not published. They are nothing more than anecdotes for anyone outside of his company. For all intents and purposes, they never happened. The Sydney group are really the only folks putting out rigorous peer-rev...

I would never pretend to speak for Paul, but I can relate to you what his positions have been in the past.

Re: EMC2 has published a polywell preprint on arXiv
...the conditions needed to instigate a proper wiffleball are apparently a bit steeper than first modeled, and it is quite helpful to have some data to tell just what it takes. Building a big machine and then trying to sneak up on a wiffleball from the bottom using inadequate equipment is a terribl...

Re: EMC2 has published a polywell preprint on arXiv
BTW as others have pointed out, this doesn't prove Polywells are a viable path to economic fusion power, it just means they crossed another significant hurdle. It's still hard to know for sure what losses will look like in reactor-sized machines, to say nothing of the electron optics. A demo reactor...

Re: EMC2 has published a polywell preprint on arXiv
Yeesh, 1.6GW net power output for a 1 meter radius? Did I read that right? It's late, must sleep... That's probably optimistic but it's still an encouraging estimate given that they've done some scaling now. That means it should cost around $200M (vs $20B for ITER which is planned to produce 500MW)....
