I recall the quote as being ~ 10e-4 to 10e-5, or 1/10,000th to 1/100,000th.
Also, figure 2 is misleading and , I believe labeled backwards. The Polywell should show a narrow bell curve centered on the disired fusion temperature. The thermalized plasma is more spread out. And, I believe, Maxwellian thermalized plasmas/ gas showe a slued Bell curve. The average temperature is below the mean temperature, so the graph should be pushed downward on the high energy side.

This has important consequences for thermalized machines like Tokamaks, where the average temperature is actually too low for optimized fusion, but the high energy tail do reach better fusion conditions. This is one reason only D-T fusion is considered possible in these machines. Aside from losses, thermalized machines have difficulty reaching temperatures for the average energy ions to fuse efficiently, so most of the fusion occurs in the relatively few ions at higher energies. Because of this, the easier D-T fusion fuel is the only one that can reach breakeven in these machines.

To error is human... and I'm very human.
I will make the corrections..
Chris & Dan,
I will make those corrections. It was supposed to be reference 1, not 51. The response to your points from November is ready. However, there is another post which should go up before then. That is nearing completion. I generally seem to work much slower than this web forum would like.
