Is there a clean way to extract Hydrogen fuel?



Honda plans to release a Hydrogen fuel cell car in 2008.
I know You can extract Hydrogen fuel by “splitting” water with an electric current, but that electricity comes from a power plant, which generates greenhouse gases. Is there a totally clean way to extract Hydrogen fuel?

How much will it cost to convert your gasoline car into a hydrogen fuel cell car?



Hey, I need an exact estimate on how much it would cost to convert your gasoline car into a hydrogen car. I would like to know how much would it cost if you do it yourself and if you took it to a car center. Thank You
