Abstract: A "Small Buoy for Energy Harvesting" has applications for use on current and future buoy systems used by the submarine fleet of the United States Navy. This work proposes to meet the requirements by converting mechanical wave energy to electrical energy using a generation system housed in a spar buoy. The energy extraction method will work with the natural orientation and motion of the buoy. Accumulated energy can be used to power a variety of systems including surveillance and communications and will greatly extend the operational capabilities of remote and independent marine based platforms.
Benefits: A "Small Buoy for Energy Harvesting" has applications for use on current and future buoy systems used by the submarine fleet of the United States Navy. Devices of this type would convert ocean wave energy to electricity, allow un-interrupted operation under all weather conditions, be easily integrated with surveillance applications for underwater and high sea state operations, and minimize or eliminate the need for batteries thus enabling enhanced functionality, higher data rates, and uninterrupted operation. Commercial applications include extended lifetime monitoring of shipping lanes, powering of instrumentation to sense oil spills, extended monitoring of fish migrations to aid the commercial fishing industry.
