Sounds like another year at least to get information with a well. Drat. Well, I'll go back to holding my breath
BTW, the links on ennresearch.com appear to be gone?

Re: Lockheed Martin’s Compact Fusion Reactor
Could be an attempt to pry out what you're up to? If it isn't, I'd like to use it as suchladajo wrote:I also have to wonder about patent overlap with Polywell. Afterall, it seems to me that there is significant prior art in the concept of pinched cusps, be they line or point.

Re: Apollo Fusion
I worked for Mike in an earlier startup. As far as I know, they're 12 people working on an ion thruster. I haven't heard anything from him recently on the fusion front, sadly.
Re: EMC2 news
The short of the long of it; Is it certain? No. "we demand rigidly defined areas of doubt and uncertainty!" :sigh: I suppose it looks like movement internally, but from the outside, I feel like I've heard that simplification before.... Nevertheless, I applaud you making it out before Heavy launch, ...

Re: SpaceX News
SpaceX BFR construction will start in 4 to 6 months It is my understanding that the ship will be built and tested prior to the booster. There are a number of design choices that concern me about the orbital vessel. The relatively large surface area will put it at higher risk for orbital debris hits...
Re: EMC2 news
I have my suspicions. The bremsstrahlung losses might be smaller by a factor. (very wishful thinking) but given most conventional thinking in a open cusp polywell they would be about 30 percent even cutting loses in half would be outstanding. I suspect that the larger size and lower well has to do ...
Re: EMC2 news
I thought the PowerPoint they published in August was very revealing. [...] For those to you may have missed it. https://arpa-e.energy.gov/sites/default/files/5_PARK.pdf Yeah, I found some slides in need of labels (because I don't remember all the details), so I'm cross-referencing to: https://iec....
Re: EMC2 news
Excellent news! Are the models running D/T fuel or P/B11? [Apologies if I missed this :( ] I assume the former, if they're aiming for "neutrons, medical isotopes" but I would think that there were many steps between scaling verification and handling the rest of the engineering challenges of a "hot" ...

Re: EMC2 has published a polywell preprint on arXiv
But, what is the average speed over the electrons travel across the machine? ... For the mean to equal the average there can be no bias in the acceleration. But there is a bias. Indeed. I'm not even sure I know what the interior looks like, nm I don't have the math to talk sensibly about what that ...

Re: EMC2 has published a polywell preprint on arXiv
The KE of the electrons of somewhere between 2 and 7 KeV implies speed of eg: 5,000,000 M/s [....] I get 50,000,000 m/s for a 7 keV electron. Yeah, that agrees with my simple math as well: v = sqrt(KE * 2 / m) v = sqrt(7kev * 1e3ev/kev * 1.6e-19j/ev * 2 / 9.11e-31kg) = 50e6m/s but then the electron...

Re: EMC2 has published a polywell preprint on arXiv
If I'm viewing the videos correctly, it looks like highest losses are out of the faces, and I thought recirculation was less certain for such losses? Recirculation should not care which cusp the electrons escape through. I'm sure I'm missing about six years of evolution in understanding here, but s...

Re: EMC2 has published a polywell preprint on arXiv
Note that this performance / breakeven is ~ 10 times worse than projected for WB100. What is different? That is hard to say as no numbers were provided about confinement, recirculation, confluence, etc. The way I read it, there was no recirculation. Lifetime of 300 bounce confinement, and the profu...

Looks like the trick is going to be good cycling.

Re: Improved Battery Technology (finally?)
Interesting. Seems like they have a cycling problem at the moment, but it looks worth further research. Thanks for the link.
