| 20110258997 | LOW COST LINEAR GENERATOR WAVE ENERGY CONVERTERS - A wave energy converter comprising: a linear generator comprising an armature and a stator; a float connected by a linkage to the armature; wherein the weight of the armature and the linkage bear downwards upon the float and one of the armature and stator comprises electrical coils and the other of the armature and stator comprises a stack of permanent magnets, the arrangement being such that during the ascending portion of a passing wave, the buoyancy of the float causes the armature to rise, and as the wave falls away, the combined weight of the float, linkage and armature causes the armature to fall, electricity thereby being generated upon the upstroke and the downstroke, the stack of permanent magnets or electrical coils of the armature being sufficiently sized in terms of deadweight to procure that the combined weight of the armature, linkage and float and any other travelling components act sufficiently against the electromotive force being generated by the linear generator upon the downward stroke to ensure that the float descends to the trough of the passing wave. | 10-27-2011 |
