Honda recently introduced the production version of the FCX fuel-cell hybrid at the LA Auto Show this week, conveniently called the FCX Clarity. The zero-emissions ride features a hydrogen-fuel-station-finding GPS system, which gets you the "gasoline-equivalent" mileage of 68mpg combined city/highway.
For the time being, Honda is leasing only 100 or so of the cars to buyers who live near one of its three hydrogen fuel stations in Southern California. So it looks like if you wanna save the world, you gotta move to Cali, baby! Hahahahaha!
