聚变能听起来似乎好得令人难以置信,零温室气体排放,没有长久存在的放射性废弃物,它是一种几乎无限量的能源供应。而采用聚变能面临的最大障碍可能是经济学问题。核聚变发电设计还没有便宜到可以取代现有的利用化石燃料发电,例如煤炭和天然气的系统。美国华盛顿大学的工程师们希望改变这一现状。他们设计了一种概念核聚变反应 Fusion can sound like an incredible amount of zero-greenhouse gas emissions, no permanent radioactive waste, and an almost unlimited amount of energy. The biggest obstacle to using fusion energy may be economic issues. Nuclear fusion power generation designs have not been cheap enough to replace existing systems that utilize fossil fuel power, such as coal and natural gas. The engineers at the University of Washington hope to change this situation. They designed a conceptual nuclear fusion reaction
