This is the story of "Ginger," officially named the Segway Human Transporter: a self-balancing, electric-powered people mover that Kamen called "magic sneakers." Code name Ginger documents the birth of a new technology and the feats of its inventor, his team of engineers, and the financiers who pursued them. Steve Kemper was the only journalist granted complete access to the Ginger project as the machine was designed, prototyped, and readied for manufacture. He takes us inside a world of ingenious engineering, in which improbable ideas become real: wheelchairs climb stairs, scooters balance on two wheels, polluted water is made clean. He reveals Kamen as few have seen him: in the heat of invention, racing against time, caught between his idealistic beliefs and his obsession to make Ginger a commercial success. He chronicles the wheeling and dealing of high-rolling investors and New Economy kingpins from John Doerr to Steve Jobs. And he delivers vital business lessons about leadership, entrepreneurship, marketing, and innovation while recounting a technological adventure that will be studied and argued about for decades.
