Biofuels

I've been reading recently about carbon sequestration and the fact that it also generates biofuel as part of the process. I know several people (not in NZ, unfortunately) who make their own biofuel at home - and there are several how to guides on the internet.

Perhaps biofuel would be an option? NZ doesn't need the vast amount of fuel that most other countries do to power its cars - there's just not as many of them.
