186亿，“人造太阳”最大单轮融资来了 这一规模远超2023年微软与Helion Energy的50兆瓦协议，成为目前全球最大聚变能源购电协议，也让“聚变商业化”从概念向现实再近一步。 资本对CFS的追捧并非偶然。自2021年起，这家公司就拿下了全球核聚变领域单轮最大的18亿美元B轮融资；今年8月28日，CFS再获8.63亿美元的B2轮融资，B轮总计融资26.63亿美元（约合人民币186亿元），刷新了核聚变领域的单轮融资纪录——背后站着谷歌、英伟达、比尔·盖茨旗下基金Breakthrough Energy Ventures等重量级玩家，是聚变行业当之无愧的“融资王”。 此轮融资后，CFS累计融资破30亿美元，占全球聚变行业总融资的三分之一；公司估值也达到约80亿美金（折合人民币约560亿元）。 与此同时，大洋彼岸的中国合肥，“人造太阳”实验装置EAST的控制室里早已爆发出欢呼——炽热等离子体被成功维持上千秒，刷新了可控核聚变持续运行的世界纪录。 从比尔·盖茨到谷歌，再到国内外不计其数的创投机构，都接连将目光聚焦向了曾被戏称为“永远还需要50年”的可控核聚变技术，全球核聚变领域已然风起云涌。 这项原先停留在实验室里的尖端技术，正加速从科研阶段走向产业前沿。 人类最早对“核聚变”的探索，其实是为了回答一个基础问题：太阳的能量从哪里来？ 1920年，英国物理学家爱丁顿（Arthur Stanley Eddington）首次提出猜想：“太阳内部可能在发生氢原子聚变成氦核的反应，这个过程会通过爱因斯坦质能公式E＝mc²释放巨大能量”——这是人类第一次把“聚变”和“恒星能量”联系起来，但当时没有实验能证明。 直到1937-1939年间，美国物理学家贝特（H.Bethe）和德国物理学家魏茨泽克（C.F.v.Weizsacker）同时提出了C-N循环理论，此后贝特又进一步算出太阳氢聚变的具体公式，从理论上证实太阳能源来自氢核聚变成氦核，才让人类终于摸清了“人造太阳”的方向。 理论落地需要实验支撑，而冷战成了早期探索的催化剂。 美国则尝试激光惯性约束路线，1972年劳伦斯·利弗莫尔国家实验室（LLNL）建成首台多束激光装置“Shiva”，靠60束激光压缩燃料触发聚变反应。不过这一阶段多是政府主导的秘密研究，虽然建成了多种实验装置，但能量消耗远大于产出，商业化仍遥不可及。 冷战结束后，各国意识到单靠一国之力难以破局，全球协作成了新的方向。1985年，美、苏、欧、日共同启动“国际热核聚变实验堆”（ITER）计划，中国于2006年加入，与欧盟、印度、日本、韩国、俄罗斯和美国共同签署ITER计划协定。它成为了迄今最大的国际科研协作平台。 与此同时，各国也在推进小型实验装置。中国2006年建成的EAST多次刷新纪录，今年更是实现了1亿℃运行1000秒；美国2009年建成的国家点火装置（NIF）在2022年首次实现净能量增益，人类终于摸到了“聚变能量可用”的门槛。 2020年代，核聚变探索迎来了关键转折：高温超导、AI控制等技术成熟让装置体积缩小、成本降低，全球碳中和需求又倒逼零碳能源突破，资本和科技大厂开始主动下场。 CFS融资纪录、谷歌协议和微软与Helion的首份协议，都意味着聚变已不再只是科研，而是有了2030年代建商业电厂的明确时间表。
