A pendulum-based system allows energy to be extracted from ocean currents
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…
The energy of marine currents could be used in a much simpler way thanks to a pendulum-based system developed by the Universitat Rovira i Virgili. The device transforms into energy the vibrations generated by water by flowing around a submerged cylinder, reducing complexity and maintenance in front of conventional turbines. The model, tested in laboratory, opens new possibilities to obtain renewable energy in marine and river environments where …
Pendulum device taps power from ocean currents
Paris, France (SPX) Jan 15, 2026 A new energy harvesting concept uses a pendulum like cylinder system to capture power from moving water in oceans and rivers. The design, developed by Francisco Huera of the Department of Mechanical Engineering at the Universitat Rovira i Virgili, converts vibrations generated as currents flow past a submerged tube into usable mechanical energy. The work appears in the Journal of Fluids and Stru
