When I came on this morning I couldn't believe this wasn't already posted here. I guess the duty falls on me then. The results for WB7 have been made available here. I'm actually kind of surprised I'm the first to post this.

After achieving "first plasma" in February, JET engineers have managed to leapfrog competing fusion technologies in the long race to net gain. "Preliminary tests indicate measured net power gain of 150% with predicted gains of up to 15x with minor modifications." http://www.jet.efda.org/pages/news/...

yeah, I'd been meaning to cut back to 5 or 6 times myself.

I've got a question I've seen on slashdot and want to make sure I'm seeing it right. I'm hoping someone here can help me out if nobody there steers me straight. Here's the objections raised: "Thermalisation alone can NEVER take you from a maxwellian to a non-maxwellian energy distribution. It doesn'...

As MSimon said, it's more like a linear accelerator in reverse. Instead of doing work to push alphas, the alphas push and you get work(DC) out.

A stupid question: I can see the charged plates decelerating the alpha's, thus alpha must have work done on the plates. But can't figure out how that translate to DC current output. Help? On a really simplistic level the alpha's are always coming through the decelerating grid in the same direction....

Why does the strength of the B field scale the fusion so dramatically? Bussard mentions this scaling in both the video and the Valencia paper, but I'm not sure what he's basing this on. Was that from his experimental results? This is a major point I see skepticism on. My take from the Valencia repo...

The best conclusion is it appears to independently verificaty that Rider's model of IEC behavior was wrong. That would answer the biggest criticism of Polywells.

"Since the proportionality constants K1 and K2 were never provided by Dr. Bussard, there is no way to correlate the two estimates." M_Simon addressed that in the spaceflight thread already. Here's a snippet: "The estimates for the k for power gain go as: n1*n2 *fusion cross section* colliding veloci...

Very interesting stuff. I have seen Indreks YouTube movies and I liked them so much I saved them to my computer hdd and converted them to *.avi's. Maybe you could put your finished work up on YouTube aswell DrMike? Btw I have a question. I know why Polywell would need a ion gun. To get higher densi...

What happens when you combine 50Kev emitters shooting electrons.. with a MaGrid.... The MaGrid is positive to the wells' negative, and the MaGrid is operating at what level charge ? Once sufficient electron density occurs, the MaGrid and the well push back at one another, equilibrium occurs, the we...

So, once the central virtual cathode is stabilised at a particular well depth, the well can be maintained at that depth just by ensuring that the electron losses are balanced by sufficient injected electron current? Does this square with the idea that the polywell system acts as a momentum transfor...

This raises an issue I've been struggling with for some time, namely, how the well depth is determined by the machine parameters. I was initially under the impression that the electron guns impart the KeV necessary to accelerate the electrons to slightly more than the resulting potential well depth...

When you say electron orbit radius do you mean larmor radius or are you referring to the electrons going into the centre and out to maximum radius? If the vacuum wall was earthed then I would imagine the electrons would slow down on arrival to it independently of its distance from the magrid, the c...
