与仍然控制宇宙太空船飞行主要手段推进器比较，反射装置功率是微小的。

Compared with thrusters, which remain the main method of steering the spacecraft, the effect of the reflecting devices is slight.

相比较而言，一支75瓦的白炽灯可达1千小时；功率大致一样的紧凑型荧光灯(俗称节能灯)可达8千到1万小时。

For comparison, a 75-watt incandescent light bulb lasts about 1,000 hours; a comparable CFL lasts 8,000 to 10,000 hours.

电机的功率和能量都比较大可以粗略的处理，但别忘了智能控制的是不会让这种情况发生的。

Motors can take rough treatment and are efficient and powerful, but forget intelligent control cause it ain't happening.
