Rotor Sails Bring Windpower Propulsion Back to Maritime Vessels
Adapting a century-old concept to modern technology and green energy demands, Finnish company Norsepower is bringing its novel rotor sails onboard a variety of marine vessels to help propel them through ocean waters. The company recently scored a number of contracts to place its auxiliary wind propulsion systems with leading fleet operators as demand mounts for greener shipping in the world’s seas. Separately, a Korean research group is investigating the use of magnetically levitated bearings to adapt rotor sails for use in coastal waters where wind is more variable. […]
