Depending on wave height and speed, as well as wavelength and water density, each buoy can produce up to 40 kilowatts of electricity.
每一個浮標最高可以産生高達40千瓦的電力，發電的多少依賴於海浪的高度以及速度，同樣也依賴於海浪的波長以及海水的密度。

According to Teruyuki Kato, the project's leader, this arrangement can measure a buoy's vertical motion with an accuracy of a few centimetres, which will pick up dangerous tsunamis in the open ocean where they are mere ripples on the surface (they rear up into killer waves only when they reach the shallows).
ECONOMIST: New ways of tracking these killer waves may help save lives
