Gaijin Biker says,
I swung by the 2006 Tokyo Fuel Cell Expo, where I saw the ENV hydrogen-powered motorcycle from British company Intelligent Energy. Its expected price is somewhere below $10,000, and it should be available in about 18 months. Apparently, riding it feels more like skiiing or windsurfing than like riding a normal motorcycle. Also, it is completely quiet. Interestingly, the fuel cell that powers the bike is removable, and can be used to run other items in your home.
