Abstract

A wave powered electric generator using direct energy conversion is described which includes, within a water and airtight, buoyant envelope tethered to a fixed point relative to the sea bottom, one or more stators and one or more elements moveable by the force of inertia, the relative motion of the moveable element within the stator generating electricity. Also within the buoyant envelope is a rectifier for rectifying the electric energy generated by the moveable element, and power transmission means for supplying the generated and rectified electric energy to a power station. In a preferred embodiment, a conductive fluid is employed as a moveable element, this fluid being passed through a concentrated magnetic field, the resultant electrical power being tapped by electrodes whose axis preferably is orthagonal to the field and direction of fluid motion.
