Introduction

The presented system is an energy converter, using gyroscopic effects to generate electrical power from the sea waves. The device consists of an external hull that is sealed and constrained to the seabed through a slack mooring. The rocking movement induced by the waves triggers the gyroscopic system placed inboard, which in turn actuates two rotary generators and produces electricity.

Technical features

The presented system is an energy converter, using gyroscopic effects to generate electrical power from the sea waves. The device consists of a hull-shaped external structure that is constrained to the seabed through a chain, loosely connected to the central body, at least two oscillating frames arranged on planes orthogonal to each other, a flywheel installed around a third axis and located within the central floater. The rocking movement induced by the waves in accordance with roll and pitch motions or a combination of both, triggers a gyroscope fixed upon an internal frame, which in turn actuates two rotary generators, producing electricity. Furthermore, an independent control unit monitors the operating conditions of the system in real-time. The planetary ring configuration of the electric generating means and their large radius allows for obtaining high torque and ensures a greater performance compared to other solutions available on the market, even in the presence of low angular velocities.

Possible Applications

• Distributed production of energy;
• Wave energy power plants;
• Marker buoys;
• Offshore radio bridges.

Advantages

• High efficiency electric generator integrated into the gyroscopic structure;
• No driveline interposition: minimum losses;
• Simple and durable configuration;
• Suitable for adverse weather conditions.
