Dean Kamen wants to change the world by changing how cities are organized. Segways, he believes, are ideal for downtown transportation. Unlike cars, they are cheap, clean, efficient, maneuverable. Unlike bicycles, they are designed specifically to be pedestrian friendly. He imagines them everywhere: in parks and at Disneyland, on battlefields and factory floors, but especially on downtown sidewalks.

How it works

The Sedway has a gyroscope that acts like your inner ear, a computer that acts like your brain, motors that act like your muscles, and wheels that act like your feet. There are 10 microprocessors, a cluster of aviation-grade gyros, an accelerometer, a bevy of sensors, two batteries and sophisticated software.
