Sharrow and MIT have both been working on toroidal propellers which have shown incredible results. In this video we look at a new design of propellers known as toroidal propellers. These have been shown to increase efficiency, thrust, and reduce the noise of both boats and drones. There could be many applications for this, such as cargo ships, electric flying taxies, and even computer fans.
