We may never be able to swim as fast as fish, but guys like Ted Ciamillo are hard at work to make sure we can at least get second place. The Greek engineer has come up with a contraption called Lunocet, which is basically a dolphin-inspired 2.5 pound monofin.
It’s lightweight and made of carbon fiber and fiberglass, and spans almost a meter. It’s capable of propelling swimmers almost 33 miles per hour, converting nearly 80 percent of the applied energy into thrust. The appendage is efficient, lightweight and fast. And can propel swimmers almost twice the speed of Michael Phelps.
