A new sail, the Mirage, has been developed that reduces fuel consumption by up to 20% by making the most of the sails that have disappeared from modern ships powered by engines and installing them on ships with engines.
Startup OutSail Shipping is looking at how to install a sail the size of a Boeing 747 on a large container ship. The Mirage can be reduced to a smaller size and placed inside a container. Even after being installed on a boat, it can be folded down when not in use and extended only when the wind blows. It is 3 m when it is reduced to a small size and reaches 60 m when it is enlarged.
