Abstract: The invention concerns an apparatus for generating power, in particular electric energy, from wave motion in water basins. It comprises at least an operating unit, including gearing provided for unidirectional rotation and to continuously operate at least one power generator in response to the movements of a control element susceptible to alternating linear movements deriving from the wave motion. Each operating unit comprises at least a main or driving shaft (11, 12; 11b) solidly carrying a driving wheel (13, 14; 13b) engaged and placed in rotation by said linear control element (15, 15b) and at least two driven shafts (21, 22; 21b, 22b) operated by the main shaft through a unidirectional drive mechanism (20, 20b) and each connectable to at least a power generator.
