Although they were mostly popular in military applications of the past, due to the benefits of the toroidal propeller, they might be making an epic return. The toroidal propeller really came into the mainstream last year when MIT and Sharrow gave a new take on an older design. These have been shown to improve efficiency and reduce noise on boats, planes, and drones.
