The central idea in this work is to read interconnection between technology and society in the field of the promotion of renewable energies. The challenges of energetic sector are the climate change, the increase of energetic mix and the improvement of a fair access to resources. Future sceneries indicate population's needs that must be satisfied with new systems and technologies. For this purpose ocean energies technologies are sure of a good future in the European and world energetic scene. In this work our attention is on the role of tidal currents and sea currents in line with large efforts in RD&D systems (Research, Development and Demonstration). We focus our studies about sea turbines with a brief reference to Kobold turbine which is a technology that is moored in the straits of Messina. Technologic innovation depends from several social factors which play an important role in the social construction process of the technology by SCOT approach (social construction of technology). 展开更多
