Western countries continue to rely heavily on coal-fired power plants built decades ago with outdated, inefficient technology that burn a lot of coal and emit considerable amounts of carbon dioxide.

西方依然对几十年前建成的低效燃煤电站很是依赖，但是这种技术耗煤量大、排放温室气体多。

But some fundamental technology hurdles—chief among them how to move enough heat out of the engine so that it won't burn itself up—have kept the concept on paper up to this point.

但基础领域的一些技术障碍让这个概念一直停留在纸上谈兵阶段，比如说，其中的一大问题是怎样让发动机充分散热，以免自燃。
