What it is: Atlas Power Ascender What it's used for: Rapidly pulling people and their gear up the side of a building or canyon The prototype of the Power Ascender was not easy to use. The battery-powered, waist-mounted climbing assistant yanked people up a dangling rope at a blistering 10 feet per second — almost 7 mph — fast enough to snap their limbs back. So Atlas, a company run by four mechanical engineers outside Boston, set the maximum speed to a more reasonable 5 feet per second and added a variable- speed trigger like on a power drill. Now customers — such as US military personnel — simply clip the 25-pound device onto a climbing harness, push any nonbraided rope through the top, and let it fly. Inside the gizmo, a network of grippers scurries up the line and ensures that it threads cleanly out the side. The Ascender's 10-kilowatt output can lift up to 350 pounds, which is no easy task. "Having that much power that close to your crotch is a huge engineering challenge," says Atlas' Bryan Schmid, "and frankly a bit risky." Sounds pretty ballsy.
