Converting the vibrations generated by water currents in contact with an object into energy. This is the basis of the new system designed by Francisco Huera, a researcher in the Department of Mechanical Engineering at the Universitat Rovira i Virgili (URV). The device harnesses the energy of water currents from the vibrations that occur when water passes around a cylinder and creates vortices behind it. This method has a very simple structure: a submerged cylindrical tube hanging from an axis that oscillates like a pendulum when the water current makes it vibrate.
A pendulum-based system allows energy to be extracted from ocean currents
