Some discourage investment in nuclear fusion, claiming that, given how far from being market-ready the technology is, our financial resources are better allocated to tried and tested energy options. The critics have a point: given that fusion can be carried out only on a large scale, its investment requirements are considerable.
有些人不赞成投资核聚变，称鉴于该技术离进入市场依然遥远，将财政资源配置到久经考验的能源项目才是最佳选择。批评人士的话有一定道理：鉴于聚变只能大规模进行，需要满足的投资需求相当巨大。
