靠水和产能比耗能多的熔化器启动的汽车，是发明者们幻想的主要产物。

Cars that run on water and fusion machines that generate more energy than they use are staples of inventors’ fantasy.

铱，通常被用于太空火箭，比铂金稀有十倍并且高度耐热，因此理论上即使它掉进岩浆中也不会熔化。

Iridium, usually used in space rockets, is ten times rarer than platinum and highly resistant to heat so theoretically it can be dropped it into lava, and it will not melt.

这种加热十分有效可以将物体质能的大致50%转化为辐射，如相对的核子熔化只能转化质能很少的百分比。

This heating is extremely efficient and can convert about 50% of the mass energy of an object into radiation, as opposed to nuclear fusion which can only convert a few percent of the mass to energy.
