A spinning gyroscope could finally unlock ocean wave energy

Ocean waves are a vast and steady source of renewable energy, but capturing their power efficiently has long frustrated engineers. A researcher at The University of Osaka has now explored a bold new approach: a gyroscopic wave energy converter that uses a spinning flywheel inside a floating structure to turn wave motion into electricity. By harnessing gyroscopic precession—the subtle wobble of a spinning object under force—the system can be tune…

Gyroscopic wave device targets broadband ocean power

Osaka, Japan (SPX) Feb 18, 2026 Ocean waves offer a vast and predictable source of renewable energy, but many existing technologies only perform efficiently under limited sea conditions. In response, a researcher at The University of Osaka has carried out a detailed analysis of a gyroscopic wave energy converter, or GWEC, to explore its potential for practical large scale power generation. The study evaluates how this device c
