The mystery invention code-named "Ginger" that has set the U.S. technology world abuzz may be little more than a morotized mini-scooter, judging from a recent patent application that came to light on January 12, 2001. A December 14, 2000 filing with the "World Intellectual Property Organization" describes a "class of transportation vehicles for carrying an individual over ground...that is unstable with respect to tipping when...not powered." The "personal mobility vehicle" pictures what appears to be a young girl balanced on a two-wheeled scooter. The Patent application by millionaire inventor Dean Kamen and six co-inventors fits descriptions made in broadcast reports by people claiming to have seen prototypes of the vehicle.
