Inspired by the pumping of the human heart, the Wave Energy Generator from CorPower Ocean can deliver up to five times more energy than current systems.
The system is made up of buoys that absorb the wave energy and send it to a geared drivetrain—instead of the more usual hydraulic pump. The drivetrain, developed by the KTH Royal Institute of Technology, is equipped with an array of smaller wheels that convert the linear motion of the moving buoy into rotating motion that spins a flywheel. According to the team, the drivetrain system allows the buoys to use all of the wave's motion, no matter how high or long the waves may be.
The system was inspired by Swedish cardiologist Stig Lundbäck's research into heart pumping.
