Aiming to bring the general public closer to this innovative reality, the activities carried out by the team (L. Carlo, A. Ruggeri, C. Iuppa, B. Bonaccorso and C. Faraci) as part of the European Researchers’ Night 2021 will be dedicated to the presentation of the main devices for extracting energy from wave motion through video, focusing on the U-OWC devices that are currently under investigation at the Hydraulic Laboratory of the Department of Engineering. Interactive experiments will be carried out with scale models, where the public will be able to understand how the experimental campaigns for the optimization of such structures work and to acquire awareness about the energy extraction potential from sea waves.
