Novel Electrical Generators For Use In Unmoored Buoys And the Like Platforms With Low-Frequency and Time-Varying Oscillatory Motions

摘要

A buoy for generating electrical energy from an roll/pitch motion resulting from a passing wave. The buoy including: a body; a pendulum member rotatably disposed on the body at a first end of the pendulum member; a pendulum mass disposed at a second end of the pendulum member; an exciter mass positioned on the pendulum member between the first and second ends; and one or more generators for generating electrical energy, the one or more generators being positioned in the body such that swinging of the pendulum member due to the roll/pitch motion causes a portion of the exciter mass to engage the one or more generators to generate the electrical energy.
