A set of pictures illustrating the SeaTwirl technique.
An illustration of SeaTwirl is seen above. 1 indicates the vertical wind turbine. 2 indicates the torus ring used by SeaTwirl to fill with water and store energy. 3 indicates the float body rotating in direct contact with the water and using the water as a roller bearing. 4 indicates the generator at the bottom of the float body. All these parts rotate together as one and the only thing not rotating is the generator axis and anchorage seen below the generator.
