Flower-like wave energy turbines could power the coasts of Japan

Flower-like wave energy turbines could power the coasts of Japan

Along Japan's coasts are structures called tetrapods. These pyramid-shaped concrete wave breakers serve to reduce the strength of crashing waves to prevent erosion in key spots along the shoreline. Researchers at Okinawa Institute of Science and Technology Graduate University (OIST) have created a technology that, like the tetrapods, helps protect the shoreline, but also generates power from waves while its at it. The researchers designed wave energy turbines that resemble flowers growing from the seabed with petal-like blades that spin. The submerged turbines would be placed in areas where tetrapods are used, namely the southern parts of Japan, and would be anchored to the ocean floor. The turbines also feature a flexible stem and blades that can endure the pounding of crashing waves . The flexible and softer materials of the stem and blades also makes them safe for any m...
