Ocean Power Technology PB150 wave-power generator
Generating electricity from wave-energy, the foot of this machine (on the left) is anchored to the seabed; the yellow disc floats above, rising and falling with wave action. This motion is used to drive a generator in the middle of the stem, sending power onshore via a subsea cable.
