Bombardier's Hot Wheel: "Following the release of the Segway, Bombardier (the makers of such things as Ski-Doo and Lynx snowmobiles) announce their prototype Embrio - a motorcycle-like unicycle that uses gyroscopes to balance itself and runs off hydrogen fuel cells. It also features a landing gear that automatically retracts once you reach 12 m.p.h. The story is at Forbes. You can also get more information directly from their website."
