Abstract
A device and a method for extracting energy from waves on a liquid from the oscillations of a column 14 of liquid in a chamber 22. The oscillations are caused by an oscillatory excitation force `Fe` produced by the effect of the waves. The phase of the velocity `z` of the column 14 of liquid and the phase of the excitation force `Fe` are brought substantially into phase by arresting the motion of the column 14 of liquid, and holding the column 14 of liquid stationary until the column 14 of liquid can be released in phase with the excitation force `Fe`.
