Problem Statement
- Conventional wave energy converters face challenges in efficiently harnessing wave energy due to sensitivity to wave direction and irregular wave conditions, requiring a robust and flexible technology.
- A directional, insensitive, and mobile wave energy converter system that can effectively harness wave energy irrespective of wave direction, while being easy to fabricate, install, maintain, and transmit electricity with minimal loss.
Technology
Bean-shaped floats:
- Designed to oscillate in response to incident waves, enabling efficient energy capture.
Hinge-joint connections:
- Facilitate free movement of floats around the buoy, ensuring adaptability to wave direction.
Hydraulic piston-cylinder arrangement:
- Converts mechanical motion of floats into pressurized hydraulic fluid.
Gearbox arrangement:
- Transforms hydraulic pressure into rotational motion to drive an electric generator.
Heave plate:
- Enhances system stability and efficiency by mitigating the effects of wave motion on the buoy.
