Our Story

Norsepower was founded in late 2012. Our mission is to reduce the environmental impact of shipping by providing efficient, easy to use, and reliable auxiliary wind propulsion for large ships. Norsepower Rotor Sail™ uses a minimal amount of the ship’s electric power to rotate cylinders on the ship’s deck. The rotating cylinders use wind to create powerful thrust. This allows the main engine to be throttled back.

The concept of rotor sails was first introduced by Finnish inventor and architect Sigurd Savonius and German engineer Anton Flettner in the 1920s. Norsepower’s vision is to bring sails back to shipping – and help to reach its goal of zero carbon emissions.
