Floating Gyroscopes Could Unlock Half of Ocean Wave Energy

A new theoretical model proposes a floating gyroscopic wave energy converter that could, by tuning the spinning flywheel and generator resistance to match changing waves, achieve up to 50% efficiency in converting wave energy to electricity. Simulations back the math, but real‑world testing and the device's energy cost are still unaddressed; researchers plan experiments and optimal control studies, with publication in the Journal of Fluid Mechanics (2026).
