Story summary

A study led by Takahito Iida of the University of Osaka finds a gyroscopic wave energy converter (GWEC) could reach about 50% efficiency in converting wave energy to electricity.
The study, published in the Journal of Fluid Mechanics, is based on computer simulations.
Yet simulations show limits, including lower efficiency in larger waves and the gyroscope's power costs, with future testing planned.
