The Oceana turbine is as beautifully sculpted as it is effective. In contrast to other designs, ours has eight blades that are individually stabilized over the rotating ring. Each blade is designed to balance axial forces exerted by the current flow, and these eight balanced blades on the rotating ring comprise the only moving part in the turbine. The ring rides on magnetic bearings and does not need a gear box to transfer electrical power. The flowing elements of the rotor ring and its blades blend seamlessly into the rest of the turbine, creating an impressive magnetic system that floats the turbine's one moving part over its chassis.
Money is an engineering parameter like voltage, force, and energy, and Oceana's turbine cuts the cost in half by supplying electricity at below $200/MWh, ensuring affordability to ratepayers. Unlike windmill-like designs, whose inferior ability to handle the force of water leads to increased production, maintenance costs and power conversion inefficiencies, the virtually zero-maintenance Oceana marine turbine can easily be scaled from a small, 6 foot model to a much larger 40-60 foot model capable of generating more than three megawatts of power, offering a wide range of potential hydrokinetic sites, from free-flowing rivers to near-shore ocean sites around the globe.
Built to last.
Most marine turbines under development mimic windmills, yet sea water is over 800 times more dense than air and embodies a harsh, corrosive environment. Oceana engineers began from scratch to design a new kind of turbine that collects energy from freely flowing currents. They built a turbine uniquely well-suited for the sea. Made with newly-developed, super-strength concrete, carbon-fiber-reinforced plastics, and other composites, the patented Oceana marine turbine is expressly engineered to harness the kinetic energy of water while diverting marine life safely through and around the device.
