Re: Prospects for Low Cost Fusion Development

Is from last November. I think it was posted here before. I don't like it much. It seems overly pessimistic and gets some technical details wrong. E.g. the assumption that a machine capable of achieving scientific break even would cost several hundred million is unfounded. Helion is building a full ...

Re: China plans fusion power research center

I also noted recently that China has been trying to encourage foreign fusion research teams that have innovative confinement concepts to share their technology. IIRC, there was a prize with a few million bucks set out. Not sure what became of it and I wonder how many fusion companies would bite on s...

Re: Tokamak Energy news

This is pretty cool. They have been making steady progress, though they are still behind their original schedule. Things will get really interesting once the HTSCs get put in. Melanie Windridge indicated recently that things with research on that is going quite well. They are still a top contender f...

Re: Z-Pinch Renaissance

Well, the FuZE prototype is really small. The expensive part is the experiments right now. Once they worked out the kinks, these things should be really cheap to mass produce. May be not as cheap as a fusor, but they will (hopefully) produce a lot more neutrons.

Small article about the Sheared Flow Stabilized Z- Pinch. Not much new in it, but still worth linking:

Re: More Helion Energy news....

Personally, I am not so sure that Tri-Alpha or General Fusion will be around in five years given my spidey sense of high tech hand-waving going on... I agree that these two could potentially falter. I am concerned about the way their reactor designs have become more and more complicated (and bigger...

Re: SpaceX News

The Starship hopper was destroyed last night by a storm :( https://forum.nasaspaceflight.com/index.php?topic=47120.msg1904371#msg1904371 Only the "fairing" part of it. The part with the tanks and "legerons" is fine. The rest was built in a few days. So it should be an easy repair.

Re: Princeton FRC work

Princeton Fusion Systems, which is a subsidiary of Princeton Satellite Systems got 1.25 million from ARPA-E to fund further development of Sam Cohen's PFRC. This is good news, since despite some impressive progress over the years, the PFRC has always been a bit of a stepchild at PPPL with just enoug...

Re: Small Tri Alpha news blurp

Someone said on reddit that Binderbauer was misquoted and that the two year time frame is not correct. It will be more like 5 years until they demonstrate break even.
