World’s First Floating Wind-Current Turbine to be Installed Off Japanese Coast

Offshore wind farms and tidal energy facilities harness the power of the wind and the ocean – but why should we have separate turbines for each task? Offshore technology company Mitsui is developing a hybrid wind-current power generating system that combines a floating vertical-axis wind turbine with an underwater turbine that generates power from ocean currents. The clever apparatus would cut down on material waste, and it could produce twice as much energy as a conventional wind turbine.

Renewable energy developers strive for improved efficiency in the solar, wind and hydro power industries – and the hybrid wind-current system effectively doubles the efficiency of a typical wind or ocean current turbine. Mitsui Ocean Development & Engineering Company says the system will provide cost-effective power generation while having very little impact on the environment.

The turbines will be large in scale; according to NHK News, the wind turbine will be 47 meters (154 feet), and the underwater portion will have a diameter of 15 meters (49 feet). The turbines will be tested off the coast of Japan later this year. If they work as well as advertised, each turbine could generate enough energy to power 300 households.

    Offshore wind turbines are awesome. This one will generate from the wind and the sea at the same time. Clever idea.

    Offshore wind farms and floating wind turbines are the future energy options as sea experiences high winds and power is cube of velocity.

    My project is about the same, since in 2007, a Bucharest, but that I also use in my plant with wave energy contribution, not just the wind and tidal currents. Click the link, and share: or my website :

    I am always wondered about taking power output from those off shore wind powerplants. This dual system is extremely interesting. But can you guys tell me about the way of power output?
