Long Endurance Compact Sonobuoy Power Source

The Navy requires a long duration, maintenance free power source for the “A” sized sonobuoy that meets a number of specific power requirements. To meet this need, we propose to design and develop an innovative power system capable of harvesting energy collected from sea wave motion and using it to greatly extend sonobuoy power for long duration, maintenance free operation. The proposed technology will continuously extract and convert to electrical power the hydrodynamic kinetic energy of ocean waves that are available in abundance at sea. The generated power will be used to continuously recharge an onboard battery for sustaining the sonobuoy’s long-term functionality and will be capable of a six-year or longer storage life. The project will develop the system design and provide proof of concept. The new energy harvesting technology to be developed in this project will also be readily adaptable to meet a wide variety of other military and commercial power needs.
