Dang, and I'll be out of town! What are the odds?

"A breakthrough demonstration happened approximately 6 month ago and they finally got permission to publish and present the results."

So can we finally say that bussard's claims were verified? Are we finally down to just engineering isues?

This has been the longest friggin' 7 years ever.... and it seems to still be dragging on :( If this keeps up, not even poly viagra will work.

edit: maybe i should calrify.. nothing will work trying to raise enthusiasm

That explains why the U. of Maryland is hosting a talk. One of the reviewers is based there.

From what I've heard, Dr. Park is talking at all the schools with big plasma groups. I actually missed his talk at LANL.

There's a chance I may be able to do polywell research. A source said if you want to do important physics, you pretty much have to do 1m x 1m; this will be very difficult for me.
Throwing my life away for this whole Fusion mess.

It would be nice to hear a report of the seminar if someone from Talk-Polywell did attend.

The slides from Dr Parks seminar are available at .
They complement nicely the arXiv preprint with more details. Enjoy! :D

So much for operating under a gag.

Let's see, what didn't they reveal? Did they use plate nuts or conventional hex nuts on their CF flanges?

Well Tom, I am glad he is putting it out in the wild now. I have told him that visibility is his friend.
Must be that the patents are fully in, so he is willing to share now.

Ooops, I guess I let the cat out of the bag a bit.
Is this the part where I admit that I have touched WB7, WB8, and Mini-B?

The revelation that Mini B achieved a calculated(?) Beta of 0.7 is enlightening. I wondered about the B field exclusion of ~ 15% and if it was because of the measuring loop being outside the wiffleball border, etc. This better defines the conditions. It also raises the question of the "sharp border" at high Beta. How close to Beta=1 is needed for the sharp border to dominate electron motions- turn around. The fusion output potential is further revealed also. Apparently, expected density scales linearly with Beta. A Beta= 1 would have a density 1/0.7 greater and fusion yield may be that squared or ~ twice as great. Compared to a Tokamak with a Beta of perhaps 0.03 gives a fusion rate ~ 0.0009 per unit of volume. This is consistant with the claimed density differential of ~ 10^19 to 10^20 particles per meter cubed for a Tokamak and ~ 10^22 for a Polywell. The resultant fusion yield is ~ 10,000 times greater per unit of volume. This is again consistent with the estimate of ~62,000 greater power density for a Polywell over a Tokamak.

This assumes similar internal plasma conditions other than density. Temperature, thermal spread, and non ion confluence areassumed to be the same. It serves as a comparison of the Beta to machine performance. Any improvement to Beta- even modest gains, in a Tokamak are significant. The problem is that the edge / macro instabilities become more difficult to control with increasing Beta in Tokamaks. This illustrates another attractive feature of Polywells , the stable magnetic field surfaces due to convexity towards the plasma. The sharp border at high Beta refines the distribution of the plasma to the B fields. In a magnatized plasma it is difficult to define where the plasma is in relation to the B field lines- it is on both sides with a gradual gradient. In the Wiffleball condition in a Polywell there is no such ambiguity. Note that electron ExB diffusion is not eliminated, but it becomes much less contributory to the description of the plasma distribution, for the electrons and indirectly for the ions also (due to the potential well ideally confining the ions to the interior of the Wiffleball).
