The Subwave Turbine
Wavecos wave power solution is based on the turbine invention from 2014 by Inge Bakke, the founder of Waveco. The Subwave turbine, called so because it will operate in the safe haven below the wave zone, is a double-winged, counter-rotating water mill, hanging about a 100 meters under a buoy floating on the surface. When the buoy is affected by ocean waves, the turbine will alternately be lifted up and sinking down in the calm and dark water in the depth, forcing the turbine blades to excert torque on the rotors and generate electricity.
This Youtube video will explain the concept. The video will open in a new window.
Our first model is tested in the sea and then horizontally in a towing tank. We have learned a lot about the function, the power potential and the efficiency. The model has a diameter of one meter. When upscaled, the power output increases by the square of the turbine diameter. For energy production, the diameter can be up to 20 meters.
