Re: EMC2 news

I think he would be interested. I am not sure he actually responded the last time we reached out. I believe that some of his questions and concerns have been addressed, especially regarding diamagnetic behaviors at the boundaries and within the cusps. I contacted him about the Q&A with Park, bu...

Re: General Fusion in the news

"breakeven" in a machine? You don't seem to understand development, this is not the milestone. :roll: For instance, in Tokamak it is guaranteed to be breakeven; it is all the other 'details' that are the problem. Uhm, I think that reaching a point where they at least have a scientific bre...

Re: More Helion Energy news....

Yes, thank you for pointing that out. Software seems to have come of age for plasma research. All the upstarts are going there. Yes, that is one of their smaller machines, easier to go to 20T in a smaller machine so they can squeeze more insight and more importantly validate their code. An encourag...

Re: More Helion Energy news....

2014 stuff repackaged. Stay optimistic. I think you missed the part where they did some 2000 shots with their Venti test device since last year. They have achieved a plasma density of 10^21 and their simulation code seems to be getting better and better too. Also it seems like they have increased t...

Re: SpaceX News

Personally I think the big problem is the regulations. Currently the FAA requires the ability to evacuate a plane within 90 seconds of the deployment of the evacuation slides. That in itself has been one of the reasons why planes haven't moved to more internal capacity. The airlines are pushing bac...

Re: SpaceX News

It was in the article on BFR that I linked (I think, much water under my bridge since then...) Sooo... rough napkin math, stealing from a comment at the BFR video link... ~$100K in fuel per flight Say 50% overhead on that per flight 100 pax (200lbs avg weight per pax = 20,000lbs pax cargo weight......

Re: SpaceX News

I got the impression that the modularity and commonality make those issues moot. You want a 9, fine. You want a heavy, just stra them together. Thebsecond stage MIGHT be different, but doesn't have to be. They found out that this is actually not the case. They had to redesign the first stages of al...

Re: Tokamak Energy news

Their approach is interesting as far as Tokamaks go because they hope that their reactors can be relatively small due to the use of high temperature super conductors and spherical tokamaks instead of the more traditional shapes. I am also excited by their quite aggressive schedule. They plan to have...

Re: General Fusion in the news

This is quite a big announcement. There are also interesting things going on elsewhere. Tokamak Energy will soon get their ST40 device ready. LPP Fusion will switch to their beryllium electrodes in a few months time and the results with that will be interesting to see. TAE is working with their lat...
