Resonant Wave Energy Harvesting Device

Abstract

An energy harvesting pendulum device is provided to oscillate in a semi-circular path on an inclined plane with a low friction surface in response to wave motion of an ocean surface. An electrical production source is mounted to an underside of the plane to convert kinetic energy of a pendulum bob of the pendulum device into electrical energy. The pendulum device can be enclosed by an enclosure floating on the ocean surface with the pendulum moving bob on the inclined plane within the enclosure. The length of the pendulum and the angle of the inclined plane are determined so that the pendulum operates in a resonant state at the ocean motion frequency. The pendulum bob can include rollers for minimal friction when contacting the inclined plane.
