In the field of renewable energy, one of the most promising technologies is wave energy. The amount of energy potentially available from the motion of waves in seas and oceans is high. Only a small part of this energy is currently converted and exploited. Systems used to extract wave energy are called Wave Energy Converters. One of these devices, the ISWEC (Inertial Sea Wave Energy Converter), uses the gyroscopic effect of a rotating flywheel to convert the energy of sea waves motion into electrical energy. This system is composed of an anchored hull capable of orienting itself with respect to the incident wave and that contains inside a gyroscopic platform.
