PowerSwim

The DARPA PowerSwim program is developing a human-powered swimming device for use by combat and reconnaissance swimmers. The device uses the same oscillating foil approach to swimming that is exhibited by many fish and aquatic birds. This propulsion approach is more than 80-percent efficient in conversion of human motions to forward propulsion. Typical recreational swim fins are no more than 15-percent efficient in their conversion of human exertion to propulsive power, and freestyle swimming converts only 3-percent.
