Waveco Subwave

Waveco's Subwave is a double-rotor underwater turbine mounted on a submersible float designed to harness the energy in ocean waves. When ocean waves interact with the device, the turbine is activated making the device rise and sink, alternately. Each rotor is made of four flexible blades mounted so that they rotate the same way whether the turbine is going up or down in the water. The device on it's own does not have a surface expression but it's intended to Since 2019, Waveco has also been developing an observation buoy, the Automar, which is envisioned to be integrated with the Subwave to power instrumentation onboard the Automar buoy.
