This device makes Navy SEALs swim like actual seals

DARPA wants Navy SEALs to be more seal-like, so they invented PowerSwim.

“Technically it’s called an oscillating foil propulsion device,” DARPA program manager Jay Lowell says, in a video from DARPA TV. “That’s a really fancy way of saying it’s a wing that helps push a diver through the water.”

The typical swimmer fins are no more than 15 percent efficient in their conversion of human exertion. By contrast, PowerSwim helps divers swim 80 percent more efficient. This dramatic improvement in swimming efficiency will enable a subsurface swimmer to move up to two times faster than what’s currently possible, improving performance, safety, and range, according to DARPA.
