you can keep your fibreglass fins
I'm interested in seeing what the US Department of defense research has come up with
to quote
"The company which gave the world the Segway has developed a revolutionary new set of swim fins, twice as efficient as the ones worn by divers today"

The Powerswim Program is developing highly efficient, human-*powered swimming devices for use by combat and reconnaissance swimmers. This program explores a new concept in swimming propulsion that uses the same oscillating foil approach to swimming that is exhibited by many fish and aquatic birds. This propulsion approach is more than 85-percent efficient in conversion of human motions to forward propulsion. Typical recreational swim fins are no more than 10-percent efficient in their conversion of human exertion to propulsive power. This dramatic improvement in swimming efficiency will enable subsurface swimmers to move up to two-and-a-half times faster than is currently possible, thus improving swimmer performance, safety, and range.
