In this episode of Climate Positive, Gil Jenkins and Kenny Gayles speak with Heikki Pöntynen, CEO of Norsepower, about how rotor sails are helping the maritime industry cut fuel use and emissions. By harnessing the Magnus effect with spinning cylinders mounted on cargo ships, Norsepower is delivering 5–25% fuel savings today—sometimes even more. Heikki discusses the company’s rapid growh, including a new factory in China to scale production, the evolving policy landscape at the IMO and EU, and why ship owners are increasingly open to wind propulsion.
