In some parts of the world, cyclists have been powering safety lights for years with devices called bicycle dynamos, which use a generator to create alternating current with every turn of the wheels.

在世界的一些地方，骑自行车的人已经通过叫自行车发电机的装置产生了多年的安全电能。当自行车车轮转动的时候一个装在上面的发电机就会产生交流电。

Design a structure in which the electrons resonate in a way analogous to a tuning fork and you have a type of generator, since the resonating electrons are, in effect, an alternating current.

设计一个结构，结构中的电子能以类似于音叉的方式共振，这就形成了一种发电机，因为共振的电子实际上就是交流电。
