I think asking fundamental questions is always a good thing. If the basic fundamentals don't look good, there is no way to make things work. Like Art said, it's easy to make mistakes and I hope I'm off by 3 or 4 orders of magnitude.

Here's and on p-B fusion using particle beams. Even in principle it's pretty darn close to impossible. 1 MW needs 10^18 interactions per second. He needed 10000 revolutions of his beams to do that, and space charge would blow things up before that. The number of interactions is the same order of magnitude for a polywell. You need 10000 bounces, or a hell of a lot more current. But lots of current blows out your magnetic confinement.

We're all after the same thing - a good understanding of reality. "Victory" comes with the "Ah-Ha!" or "ah-shit!" It's the understanding that matters.

I have to admit that Art's comment about Dr. Nebel's response upthread ("'it will be difficult to draw accurate quantitative conclusions' is pretty weak") is a good one; if this turns out to be a fundamental limitation, we'd better find out now.
