Wasn't there another article a few weeks a go that said the energy required to turn organic matter into usable fuel was more than the energy contained in the fuel? I still think bio fuels are a long way off.
You are right about the cost outweighing the benefit. However, if you drive a diesel it will happily run on cooking oil like Mazola, or cheaper brands. It is illegal because you are not paying tax though.
If that can be overcome strike a deal with KFC and McD's to take all their old cooking oil off their hands instead of them having to pay to dispose of it. Run it through a good filter and hey presto free fuel!!!
It depends how powerful you want the fuel. You can add White Spirit to improve combustion. If you are really adventurous you can add some Nitro fuel as used in radio controled cars, boats and planes. That is simply castor oil with nitro added.
You should google it it is a very interesting and simple subject
