For anyone interested in even smaller reactors, I'm working on a device that believe might be able to scale down to the size of a button cell battery. http://www.ddprofusion.com http://www.ddprofusion.com

  Do you have any published papers on this? I’m fascinated!

    They link a patent on their page: http://www.ddprofusion.com/US10354761.pdf http://www.ddprofusion.com/US10354761.pdf

    I haven't yet found anyone to help me to describe and analyze it with rigor.

    Some related discussion by fusor practitioners about the concept. It's a tantalizingly complex field where many have attempted and failed to find the pot of gold at the end of the rainbow: https://fusor.net/board/viewtopic.php?p=78286#p78286 https://fusor.net/board/viewtopic.php?p=78286#p78286

      Yeah, that's me there as well. I've been working on this for a few years.

  Is this somehow related to cold fusion?
  - pontifier 6y ago
    Not at all. I believe a Penning trap could have an oscillation mode which causes a single species to reach extremely high densities for short periods of time. I'm hoping to try for a density record with my prototype. It may not happen, but I think I can get higher densities than NIF.

There is a list of active fusion organizations at : https://www.fusionenergybase.com/organizations https://www.fusionenergybase.com/organizations Also the fusion subreddit is reasonably active : https://old.reddit.com/r/fusion/ https://old.reddit.com/r/fusion/ For anyone after an up to date book on fusion The Future of Fusion Energy is good: https://www.goodreads.com/book/show/43700662-the-future-of-fusion-energy https://www.goodreads.com/book/show/43700662-the-future-of-f...

  I can't say anything about that website since I am not familiar. The subreddit is godawful and no one should waste their time. The book is top notch and everyone interested should give it a read (assuming you care enough and have enough disposable income to afford it, it is not cheap).

    Where do you get fusion news? There is news on that subreddit of all the fusion startups, even the lesser known ones like HB11. The Kindle version of The Future of Fusion Energy is $US 12.

      Well, I work on a fusion research machine in an academic setting, so weekly seminars. I hear about startups from coworkers, but I’m not too interested in them because I am jaded about their prospects. I understand that they are considered moonshots by VC, but I still think their chance of success is 0%. I’d love to be proven wrong, but a lot of smart people have been working on this for a long time. I don’t think we’ll be shaking out any magical revelations anytime soon. Advancements in turbulent transport is where the important work lies imo. Anything funded by DoE (which is a lot) necessarily has to keep all publications public. Just because you don’t have a subscription to Nuclear Fusion or IEEE Transactions on Plasma doesn’t mean you can’t learn about what’s going on for free. It’s unfortunately just a pain to find. Look for papers hosted on websites of projects at PPPL, ORNL, UWisc, IPP, etc.
