Harnessing wave power in the seas around Scotland, a new hydraulic energy-capturing device shows promise. The floating squid-like mechanism is made of a central ballast shaft and three attached arms. As the arms move along an X,Y, and Z axis the hydraulic connecting points harness the energy as the buoys move. The design is scalable, you can connect multiple buoys, and the inventors hope to have nearly a mile of the buoys floating by 2024, producing 100 megawatts of energy, enough energy to power more than 14,000 homes.
