Just Hangin' Around - MIT graduate student, Nathan Ball, hangs 50 feet in mid-air from his battery-powered rope ascender, a device that can raise more than 250 pounds at 10 feet per second. Ball is the 2007 winner of the $30,000 Lemelson-MIT Student Prize, an award that recognizes students at MIT who have demonstrated remarkable inventiveness.
