Wave energy’s huge potential could finally be unlocked by the power of sound

AI generated summary

Ocean waves have immense potential as a renewable energy source, producing an estimated 50 to 80 trillion watts of power globally. Despite this, current technologies for harnessing wave energy face efficiency challenges, particularly in deeper waters. Recent research suggests that underwater sound waves can enhance surface waves, making them more powerful and potentially more viable for energy production. This interaction, known as triad resonance, allows acoustic waves to increase the amplitude of surface waves, which could improve the efficiency of wave energy devices.

Additionally, the research explores the possibility of using acoustic waves to mitigate tsunami risks. By manipulating underwater acoustic waves, it may be possible to reduce tsunami wave heights, as demonstrated during the 2022 Tonga earthquake. The study also highlights the potential of using hydrophones to monitor acoustic waves for real-time tsunami prediction, complementing existing technologies. This approach could enhance early warning systems and contribute to making coastal communities more resilient to tsunami threats.
