The concept of capturing and converting the energy available in the motion of ocean waves to energy.

An instrument for recording ocean waves. Most recorders are designed for recording wind waves, that is waves of periods up to about 25 seconds, but some are designed to record waves of longer periods such as tsunamis or tides.

Same as wave pole.
