[00:00:00]Have you ever wondered what those spinning columns [music] on ships are?

[00:00:03]They are called rotor sails and this is how they work. When wind hits the rotating sail, it creates a pressure difference that pushes the ship forward.

[00:00:11]As a result, ships can reduce [music] their reliance on engines, save fuel, and cut emissions by up to around 20% depending on wind conditions. Rotor sails are made from lightweight materials and are usually tall and narrow, making them easy to install on large [music] vessels without affecting cargo space.
