Their particularity lies in their bio-inspired forms. BioWAVE imitates the movement of giant algae seaweeds, called kelps. The system, which is 26 metres high and anchored in the seabed, is topped by three air-filled cylinders A , the top part of which is close to the surface. It captures the mechanical energy of the swell, which is then transmitted by hydraulic jacks B to an onboard O-Drive module C that converts the mechanical energy into electricity.

BioSTREAM is an immersed structure shaped like a fish s caudal fin that moves in time with the tidal currents. The direction is controlled by an onboard computer D . Unlike BioWAVE, it is anchored at greater depths in order to capture the energy of the waves more efficiently. The oscillating movement actuates two hydraulic jacks E that transmit their energy to an O-Drive module F that is connected via a cable, like BioWAVE.

These environmentally harmless mechanisms can produce up to 2 megawatt hours per year, or the equivalent of the consumption of 1,600 households, and up to 100 megawatts, if they are networked. The major advantage of this energy is that it is produced constantly.
