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。
And you can hear the chains a-jangle as you go about and reach for the other buoy.
甚至在他们调转船头到达另一个浮标处时,他们仍然能听到那铁链发出的当啷声。
