A novel floating vertical axis wind turbine (VAWT) design for offshore wind farms is being advanced by Norwegian startup company World Wide Wind.

In contrast to horizontal axis wind turbines, VAWTs accept wind energy from any direction, rather than needing to turn to face into the wind, eliminating the need for heavy drivetrain and other components at the top-end. These new turbines sport two sets of blades, one stacked on top of the other, that are arranged to contra-rotate: one will rotate clockwise while the other rotates counterclockwise.

The contra-rotating vertical turbine architecture affixes one turbine to the rotor and the other to the stator, doubling the relative speed of rotation as compared to a static stator. The company believes its VAWT will reduce the levelized cost of energy to $50/MWh and expects to be able to produce units towering up to 400 m (1,312 ft) high, with a 40 MW capacity. The new system would dwarf the 16 MW produced by the world's largest wind turbine, the MingYang Smart Energy 16.0-242, which stands at 242 m (794 ft) tall.

A 3 MW model is planned to be demonstrated by 2026, with the 40 MW system scheduled for production as soon as 2029.
