Welcome to c/news! Please read the Hexbear Code of Conduct and remember... we're all comrades here.
Rules:
-- PLEASE KEEP POST TITLES INFORMATIVE --
-- Overly editorialized titles, particularly if they link to opinion pieces, may get your post removed. --
-- All posts must include a link to their source. Screenshots are fine IF you include the link in the post body. --
-- If you are citing a twitter post as news please include not just the twitter.com in your links but also nitter.net (or another Nitter instance). There is also a Firefox extension that can redirect Twitter links to a Nitter instance: https://addons.mozilla.org/en-US/firefox/addon/libredirect/ or archive them as you would any other reactionary source using e.g. https://archive.today/ . Twitter screenshots still need to be sourced or they will be removed --
-- Mass tagging comm moderators across multiple posts like a broken markov chain bot will result in a comm ban--
-- Repeated consecutive posting of reactionary sources, fake news, misleading / outdated news, false alarms over ghoul deaths, and/or shitposts will result in a comm ban.--
-- Neglecting to use content warnings or NSFW when dealing with disturbing content will be removed until in compliance. Users who are consecutively reported due to failing to use content warnings or NSFW tags when commenting on or posting disturbing content will result in the user being banned. --
-- Using April 1st as an excuse to post fake headlines, like the resurrection of Kissinger while he is still fortunately dead, will result in the poster being thrown in the gamer gulag and be sentenced to play and beat trashy mobile games like 'Raid: Shadow Legends' in order to be rehabilitated back into general society. --

They talked about Q value alot, but why compare those to pure-fusion test projects? Strapping a nuclear reactor is obviously going to generate more energy than an experimental device not designed to break even. What I want to know is it predicted to be more or less efficient than a reactor by itself, what other advantages it might have, is it capable of recycling nuclear waste for example.
One advantage of these reactors is they're completely meltdown proof. You design the fission component to be sub-critical - the fission core can only maintain a reaction as long as the neutron flux from the fusion reactor is maintained. The neutron flux doesn't just enhance fission, it's a necessary component for the fission to keep going at all. And the fusion portion doesn't make net energy, it's just a glorified way of turning electricity into neutrons.
If anything goes wrong, you just flip a switch and shut down the fusion part of the reactor. Temp starts increasing too much? A sensor flips a switch and the fusion reactor shuts off automatically.
