How spinning sails are cutting fuel use in modern shipping
SMRTR summary
Rotor sails — spinning vertical cylinders that harness wind through the Magnus effect — are helping modern cargo ships cut fuel use by 10–15%. In late 2024, three rotor sails were installed on the bulk carrier Chinook Oldendorff, delivering roughly 3 MW of extra propulsion while consuming only 50 kW of electricity, proving wind power remains a practical, low-cost path to reducing shipping emissions.
