It's called ENV, pronounced "Envy".
I use, and they should use, the term "motorcycle" advisedly. With a 50mph top speed which it reaches in 12 seconds, this isn't going to displace the Yamaha YZF-R1 any time soon. "Scooter" might be a better word to use, and a better market to shoot for. But with no exhaust except water vapor, and a cost of $3 to $4 for a five-ounce hydrogen fillup that will take it a hundred miles, it'd make a hell of an inner-city runabout.
The manufacturer, Intelligent Energy, projects a possible retail cost of about $1,500 for a home-sized reformer unit that would produce hydrogen from natural gas, ethanol, or biomass. Turn kitchen scraps into usable fuel? Hey, I could get all over that.
