Day of the Dolphin

Swim twice as fast as Michael Phelps:

“The human body does many things well, but swimming isn't one of them. We're embarrassingly inefficient in the water, able to convert just 3 or 4 percent of our energy into forward motion. (Even with swim fins, we're only 10 to 15 percent more efficient.) But a new, dolphin-inspired fin promises to fuel the biggest change in human-powered swimming in decades, putting beyond-Olympian speeds within reach of just about anyone.

Culminating decades of research, engineer and inventor Ted Ciamillo, an inventor and engineer in Athens, Ga., who made his name (and fortune) building high-performance bicycle brakes, created what he has dubbed the Lunocet, a 2.5-pound (1.1-kilogram) monofin made of carbon fiber and fiberglass that attaches to an aluminum foot plate at a precise 30-degree angle. With almost three times the surface area of conventional swim fins, the semiflexible Lunocet provides plenty of propulsion. The key to the 42-inch- (one-meter-) wide fin's speed: its shape and angle, both of which are modeled with scientific precision on a dolphin's tail.” via Scientific American.
