Sabine Hossenfelder explains how close nuclear fusion really is to break-even, and why headlines about ITER and lab milestones are misleading. She distinguishes plasma gain (Q plasma) from whole-system gain (Q total) and shows the latter is still far below one.
HN 推薦的原因： HN commenters post it under nearly every fusion breakthrough story as the standard reality check on Q-factor hype.
