The plasma must, though, be kept away from the reaction vessel's wall.

但是，等离子体必须远离反应容器的壁。

As Michel Laberge, its boss, explains, the fuel is still a plasma, but the reaction vessel's lining is a rotating cylinder of liquid metal—lithium in the prototype, and a mix of lithium and lead in the putative commercial model.

正如它的老板 Michel Laberge 解释的那样，燃料仍然是等离子体， 但反应容器的内衬是一个旋转的液态金属圆柱体——原型中是锂，而在假定的商业模型中是锂和铅的混合物。
