Depending on wave height and speed, as well as wavelength and water density, each buoy can produce up to 40 kilowatts of electricity.

每一个浮标最高可以产生高达40千瓦的电力，发电的多少依赖于海浪的高度以及速度，同样也依赖于海浪的波长以及海水的密度。

As the buoy lifted with the surge, a 40-watt light bulb on top of it, powered by wave energy, lighted up.

当浮标被海浪抬起来后，它顶上一盏40瓦的灯泡，被波浪能量的供电点亮了。
