Sabine Hossenfelder 深度解析了可控核聚变距离实现真正的“能量盈亏平衡”究竟还有多远，并揭批了各类关于 ITER 和实验室里程碑的新闻通稿是如何误导大众的。她清晰区分了等离子体增益（Q plasma）与全系统增益（Q total），指出后者的能量产出目前依然远不及投入。
为什么 HN 推它
每当有新的核聚变突破上热搜，HN 评论区都会刷出这个视频，堪称戳破 Q 因子炒作泡沫的标杆级清醒剂。
「Sabine Hossenfelder 这期绝对是必看之作。」HN 网友原话：Mandatory video by Sabine Hossenfelder
英文原摘要（HackerTube / Claude 整理）
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 commenters post it under nearly every fusion breakthrough story as the standard reality check on Q-factor hype.
