Re: EMC2 has published a polywell preprint on arXiv

...the conditions needed to instigate a proper wiffleball are apparently a bit steeper than first modeled, and it is quite helpful to have some data to tell just what it takes. Building a big machine and then trying to sneak up on a wiffleball from the bottom using inadequate equipment is a terribl...

Re: EMC2 has published a polywell preprint on arXiv

BTW as others have pointed out, this doesn't prove Polywells are a viable path to economic fusion power, it just means they crossed another significant hurdle. It's still hard to know for sure what losses will look like in reactor-sized machines, to say nothing of the electron optics. A demo reactor...

Re: EMC2 has published a polywell preprint on arXiv

Yeesh, 1.6GW net power output for a 1 meter radius? Did I read that right? It's late, must sleep... That's probably optimistic but it's still an encouraging estimate given that they've done some scaling now. That means it should cost around $200M (vs $20B for ITER which is planned to produce 500MW)....

Re: 10KW LENR demonstrator (new thread)

I thought it was interesting that NRL claimed the other day to have a process to produce jet fuel from seawater for $3-$6, for which they were not immediately condemned by all right-thinking people. -- And why should they be, or were you just being facetious? Indeed, Bussard himself made some... op...

Re: 10KW LENR demonstrator (new thread)

no one seems to have the kind of solid theoretical grasp needed for effective mass production. Or it just doesn't do what he claims. Probably not. But one could say the same of most claims for most new technologies. But it's one thing to say e-CAT's not going to live up Rossi's claims that it will ...

Re: 10KW LENR demonstrator (new thread)

Thanks Axil. I mention a few of them in the last chapter. I mention Defkalion which I have an enormous difficulty to assess all the time. I still have strong doubts about Defkalion, but they have been the one that have seemed to have something close to Rossi that I knew of. But I would not say that ...

Did we ever figure out if they're trying p-B11 yet? That was the WB-8.1 goal iirc.

Re: Recovery.Gov Project Tracker

Why not do the pump the water up the mountain, and let it drain thing using wind (or other low load/low efficency when underloaded capacity at that moment) as the source? The losses and costs at every step would very likely make that uneconomic even in a best-case scenario. This is partly because i...

Re: 10KW LENR demonstrator (new thread)

Thanks for sharing Axil. I wonder how Rossi's longer-running machines are doing? I suspect Rossi still doesn't have a strong understanding of the effect he's trying to commercialize. McKubre's take is probably correct and would be typical for efforts of this kind. The effect may not even be commerci...

Re: Convergent Scientific videos are up.

Steady state just means the device is cooled and doesn't operate in pulse mode. It has no implications for the physics (at least in theory) because the time scales are much smaller than the pulses. The drive current is what keeps the machine at the quasi-neutral limit. In that respect it's pretty ty...

Ha! 1.6T is nothing, FF claims to create 100,000T magnetic fields.
