Figs. 15A-C are dimensional schematics of a large-scale WEC for deployment in highly active wave fields in accordance with various embodiments of the present invention. Without device tuning, a differing wave period will result in differing WEC response and a different phase relationship with respect to the wave. However, one skilled in the art will realize the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
In yet still further embodiments, requirements may exist to prevent uninhibited 360-degree float 902, 904 rotation. Solving the conflicting problems of survivability and cost of energy is achievable, yet success in doing so requires a significant improvement over the state-of-the-art (STOA). WECs in accordance with the present disclosure may take advantage of the rotational nature of ocean waves to capture the incident energy with floats that are rotationally coupled to produce mechanical torque in the central housing.
Wave energy is a globally-desirable resource and has the potential to be a cost-competitive and important component of a diverse mix of clean, renewable energy resources. 5-7.
