Core Mechanisms and Key Innovations
Triad Resonance Phenomenon
A cornerstone of this technology lies in a fascinating process known as triad resonance. This phenomenon occurs when two underwater acoustic waves align their frequencies with a surface wave, resulting in a significant increase in the surface wave’s height and power. Such amplification can enhance the performance of energy capture devices like turbines and oscillating water columns by over 30%, a leap forward in efficiency.
The implications of triad resonance are profound, as it directly tackles the inefficiency issues plaguing wave energy systems.
