Bottom Wave Generator
Green Wave’s wave turbines have been developed with the philosophy that they should be environmentally non-invasive and uncomplicated – and tough enough to work in the rough environment of the ocean. Our turbine consists of nothing more than a structurally reinforced fiberglass cylinder with a large propeller (or impeller) inside that’s connected to an electric generator. No oil or hydraulics are involved. The turbine is vertically anchored into a fixed spot (outside the breakers in a location predetermined based on local stakeholders’ recommendations) with just its top peeking out of the water. The generator is also easily connected to other Green Wave turbines that make up the power plant, or the substation nearby on land. The generator’s production relies on the water rising and falling inside the cylinder, to turn the propeller and generate electricity.
