2011 IEC Confrence slide presentations are now up
Some interesting reads. There are two presentations on Polywell.

The Sidney group reports on confinement, note they worked with low Beta conditions.
Joel Rogers analysis has evolved from impressions presented from last year. The 6.6 meter (13.2 M diameter) breakeven machine is for P-B11. I didn't see D-D discussed (still need to read the slides in greater depth- wish the verbal dialog was included). Some needed/ possible (?) improvements may shrink the size further.
6.6 M radius, is not too far from Bussard's 2 to 2.5 M radius estimate for P-B11 (for breakeven or for useful positive Q?).

To error is human... and I'm very human.
Joel wants to add "downscattered" (e-) "scrapers". That is his big change this year. I also wonder where he gets his Polywell diagrams. It would seem to be a patent application that I have not seen. Wall mounts, etc.

It's from his own patent, Modular Apparatus for Confining a Plasmaladajo wrote: I also wonder where he gets his Polywell diagrams. It would seem to be a patent application that I have not seen. Wall mounts, etc.
I noticed that, 14ish meters across is still kinda big... I really do hope it doesnt get any bigger than that. In other news, I emailed dr. Khachan about going to grad school at Sydney University, and he told me to try a school in the states... sigh...ladajo wrote:I do not recall seeing that before. Hmmm. Am I developing CRS?
Thanks. Joel has been a busy boy for someone who has said it does not work a couple of times.
What schools does IEC? Other than Wisconsin.
Throwing my life away for this whole Fusion mess.
B fields look low due to use of commercial copper magnets designed for continuous operation. I don't see a discussion of scaling with increased B fields that would be possible with superconductor magnets. It is very likely that I missed it due to poor reading skills on my part.
Best regards
PS Nice patent, did he get out in front of EMC2 on the magnet support?

Counting the days to commercial fusion. It is not that long now.
I didn't see any real evidence of a wiffleball effect in his analysis. I get the impression it ONLY covers simple cusp effects. In which case it would have to be MUCH larger that the Polywell EMC2 is investigating.Robthebob wrote:I noticed that, 14ish meters across is still kinda big...

Did I miss something?
I think he talked about whiffleball, but just used different words. Afterall, the cone reduction of the cusps is afterall what whiffleball is all about.
It is curious that he has flown this, and EMC has yet to re-issue a round of patent submission since the last lot ran out.
My take is that this will open up some sort of legal battle if things become fully viable.
It is curious how Joel's drawings and write up are very similar to public postings we have had from EMC2. To include the vacuum chamber as displayed on the EMC2 webpage.
Makes me a little uncomfortable.

IIRC he did mention some cusp-plugging effects in past presentations.KitemanSA wrote:I didn't see any real evidence of a wiffleball effect in his analysis.

Great to see he's still working on this.
n*kBolt*Te = B**2/(2*mu0) and B^.25 loss scaling? Or not so much? Hopefully we'll know soon...
