Meet your friendly neighborhood Spider-Kid! It's the stuff of childhood dreams, right? A boy in Cambridge, England, can climb the walls just like his favorite superhero.
OK, Vacuum-Boy's powers are slightly less subtle than Peter Parker's. But you have to love 13-year-old Hibiki Kono's creativity. He spent five months designing and building his Spider-Man gear from a pair of cheap 1,400-watt vacuums bought at Tesco (like a British Wal-Mart) and some suction pads.
Nothing puts the DIY in climbing a building like a homemade pair of suction gloves. Inventor Jem Stansfield used his vacuum-powered device to clamber up the 120-foot aluminum wall of the White City building in London last week.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.
