ISWEC Inertial Sea Wave Energy Converter
The ISWEC point absorber consists of a floating hull with one or more internal gyroscopic groups; the coupling between the hull’s pitching and the flywheel rotational motion, generate gyroscopic forces that are then converted into electric energy by a power take-off system. The device is modular such that the gyroscopic unit can be changed in order to vary the nominal power of the converter. The energy produced may be used to power offshore infrastructures or small coastal communities.
The key aspect of this technology is the gyroscopic system, consisting of two 10-ton flywheels whose angular velocity can adapt to the working sea conditions to optimize the performance and energy absorption of the device, increasing the flexibility of the converter.
