国运之战，这个堪比“两弹一星”的超级计划，中国发力了 可控核聚变，一个真正关系国运的战场。 其中，中国投资增速极为显著： 短短三年内，中国对可控核聚变的股权投资出现了几乎“从无到有”的爆发式增长，迅速一度超越美国。 要知道，可控核聚变虽然被誉为“能源问题终极方案”，但难度同样是“珠穆朗玛峰”级别的，科学界曾经有一个说法：可控核聚变距离完全实现，永远还有50年。 更让人意外的是，今年2月，美国核聚变“独角兽”的Helion Energy获得了一笔4.25亿美元的融资，投资者名单中不仅有光速创投、日本软银等，甚至还出现了OpenAI的创始人Sam Altman。 为什么中美对于核聚变领域的投资，先后出现大幅升温，吸引了最前沿科技大佬的目光？ 可控核聚变作为人类能源问题的理想解决方案，已成为大国科技竞争的前沿阵地。 据日本调查公司Astamuse的数据，2015年以后中国在核聚变领域申请的重要专利大幅增多，超过了美国。 据澎湃新闻报道，中石油此次增资昆仑资本，是为了入股中国聚变能源有限公司（下称中国聚变公司），成为这家公司的仅次于中核集团的第二大股东。 公开信息显示，中国聚变公司与上文提到可控核聚变创新联合体同步挂牌成立，其意味相当明确： 以及上海的核聚变初创企业能量奇点，投资方除了蔚来资本，红杉中国种子基金、蓝驰创投，甚至还有游戏公司米哈游。 天量资金所向，一时风起云涌。 今年2月，同为美国核聚变“独角兽”的Helion Energy获得了一笔4.25亿美元的融资，投资者包括OpenAI的创始人Sam Altman。 老钱与新钱都争相投入，核心的焦虑点只有一个：能源。 可控核聚变，正是解决能源问题可能的一个“终极答案”。 如果实现可控核聚变，这种“奢侈”的供电方式，完全有可能实现。它给人类带来的改变绝对是颠覆性的，可能远超前三次科技革命。 要知道，核聚变的原材料是氢的同位素氘和氚，它们广泛存在于占地球面积70%的海洋中，几乎可以说是无穷无尽。 而且理论上，1克核聚变燃料可产生的热量与约8吨石油产生的热量相同，是目前核电站产生核裂变反应产生热量的4倍。一旦掌握可控核聚变，人类可利用的能源规模只取决于核聚变反应堆的数量，拥有了近乎无限的能源，打开无穷的可能性： 比如，可以大规模蒸馏海水彻底解决缺水问题，甚至制造人工气候，让沙漠戈壁成为绿洲； 这是因为，可控核聚变面临两座难以逾越的“大山”。 这需要的最低温度大概是5000万至1亿摄氏度。目前人类能造出的熔点最高的物质——铪合金，熔点也不过4215摄氏度。任何材料接触到核聚变产生的等离子体，都会被瞬间熔毁。 目前国际上主流的技术路线是磁约束聚变，用强大的磁场“关住火球”，让等离子体在一个稳定空间中持续“燃烧”。其中最广泛采用的就是托卡马克装置，全球已经有100多台建成并运行。 世界上在建的最大托卡马克装置是1985年由欧盟、中国、韩国、苏联、日本、印度和美国等大国共同立项建设的国际热核聚变实验堆（ITER），原定今年完成，但工期一拖再拖，投入使用时间已调整至2034年。 EAST局部（图源：光明日报） 但这还不够，可控核聚变还有第二个难题：实现能量的正收益。
