Abstract
An energy-harvesting buoy is provided comprising an air-pressure generator, such as a piezo-electric generator, or any other generator that can harvest energy from an air pressure. The energy harvesting buoy consists of a first float and a second float. An air pressure is created when relative vertical motion occurs between the first float and the second float which drives an air pressurization means such as a piston driven air pump using a linkage member pivotably mounted between the respective floats. The generator uses the air pressure from the air pressurization means to drive the generator to generate electrical power.
