Superman may not be the only one able to leap a building in a single bound thanks to graduate student in mechanical engineering at Massachusetts Institute of Technology, Nathan Ball.

The Atlas rope ascender lets a fully loaded firefighter reach the top of a 30-story building in 30 seconds. This compares to the six minutes it could take to climb the stairs with 80 to 100-lbs. of equipment. The device is the size of a hand-held power tool and can lift a 250-lb. load more than 600 ft. into the air at about 10 ft./sec. on a single battery charge.
Similar to the way anchors are raised and lowered on ships, the rope-handling mechanism produces a tighter grip each time the rope wraps around a cylinder, continuously tightening as more weight is applied. In Ball's patent-pending design, the rope is between 3/8-and-5/8-in. in diameter. This new device could be used in rescue work but also recreationally, for climbing and exploring caves. "It could eliminate the need for ladders and heavy gear," says Ball.More Information:
