Humans can get better 'gas mileage' using unpowered exoskelton

It's taken millions of years for humans to perfect the art of walking. But research results published today in the journal Nature show that humans can get better 'gas mileage' using an unpowered exoskeleton to modify the structure of their ankles. The device puts an extra spring in each human step, reducing metabolic energy consumption by 7 percent below walking in normal athletic shoes.
