So, you think concept cars that run on alternative fuels are thing of the future?...Well that´s not entirely true, at least not for Honda.
Unlike GM who´s Volt concept car has no real (actual, certain o "It may never see the light") launching date, the FCX, made by Japanese automaker Honda, which runs on hydrogen fuel cells, and has no emissions (other than steam), is upon us. Japanese automaker is really up to the challenge of getting the car on Americas Roads (starting at LA) A. S.P. 
According to Honda:
"The FCX Clarity is ready for the road. A limited number of these groundbreaking vehicles will be leased to Southern Californians starting during the summer of 2008. "
Check their site, you might get approval for a leasing.
