In The Dark

Rick Nebel, the lead guy in Polywell Fusion Research has a few things to say about his current state of knowledge with reference to the Polywell Fusion Reactor. He also discusses some rather technical questions about his research and findings. You can read those by following the link.

To a certain extent we are in the same boat as everyone else as far as the previous experiments go since Dr. Bussard’s health was not good when we started this program and he died before we had a chance to discuss the previous work in any detail. Consequently, we have had to use our own judgement as to what we believe from the earlier experiments and what we think may be questionable.

That may explain why the US Navy has contracted Rick's company, EMC2 Fusion, (formerly run by Dr. Bussard until his death) to do several different measurements on the plasma including density, and magnetic fields.

In various Polywell discussion groups a lot of the talk is focused on how little published information there is about Polywell. The above may be part of the explanation.

I must say that this news is a surprise to me. I was under the impression that the knowledge was out there. Now it appears that however much there was a lot of it died with Dr. Bussard. However, some very big names in plasma physics, like Nicholas Krall, who wrote Principles of Plasma Physics are interested in the progress of the Polywell reactor. In fact Dr. Krall who famously said, "We spent $15 billion dollars studying tokamaks and what we learned about them is that they are no damn good.", wrote a paper with Dr Bussard titled Forming and maintaining a potential well in a quasispherical magnetic trap. So despite our current state of knowledge I'd have to say the effort to find out more is very worthwhile. Especially given the relatively low cost of knowledge. So far the US Navy agrees. Here is what Dr. Nebel recently said about what the experiments show.

"There's nothing in there that suggests this will not work," Nebel said. "That's a very different statement from saying that it will work."

If we upped the burn rate of the project from $2 million a year to $10 million a year we could learn more faster. Which means faster decision making. And that is almost always a good thing. Right now we are in the position of not having enough solid information. More is better.
