Gov,

Your information regarding the time frame for Honda's FCV (Clarity) is off a bit.:)   They've already started to roll off their assembly lines in Japan and will be shipped in limited numbers to this country (actually CA) soon.

Sorry, kinda swamped here with work.  It will be 3 or 4 years before you will see them at Honda dealerships nationwide.  

Flake-

The homestation for filling the vehicle they are pushing emits CO2, not the car.  You state its not a solution, but you must clarify what solution you are talking about.  Its not a solution to reducing pollution, but is a solution to the current energy issue.

The other issue is refilling the vehicle.  The capital requirements alone to convert gas stations to hydrogen filling stations is high.  Hopefully, congress will issue tax credits to help convert these faster.
