Norsepower’s unusual take on wind power for modern maritime mobility is a far cry from the familiar sight of canvas sails flapping in the breeze. Even the high tech rigid sails of the yacht racing circuit look somewhat sail-like. Nevertheless, there it is. The company has developed a sail that looks like it should be belching smoke instead of deploying wind power.

If you’re wondering how it works, that’s a good question. Norsepower’s pipe-shaped Rotor Sail takes advantage of something called the Magnus effect, which refers to the pressure difference created when an object moves through air.
