明显的是鱼的速度（最多70kph ）和极端游泳效率，其身体结构的进化可以减少阻力，从而在海洋移动中保存了体力。
These are evident in the fish’s speed (up to 70kph) and extreme swimming efficiency, evolution having honed its body to reduce drag and thus conserve strength during transoceanic migrations.
ESS语重心长的表示：自力更生一般来说当然是好的，但是如果走了极端，那么就既不有效率也不公正。
“While self-reliance is a good principle in general, it may be neither efficient nor just if taken to extremes,” noted the ESS.
高效率的机器可以成群安放，在极端天气下也能生效。
The efficient machines can be arranged in clusters, and they can function in extreme weather.
