I heard they are getting rid of red diesel anyway soon. I think a lot more people are going to be looking for alternatives then too. I also heard that you can use heating oil instead of red diesel with a tiny additive? Dunno if that's true. I would LOVE to know how to make biofuel. I looked it up once and it looked pretty complicated.
I couldn't believe the peddle video!! I have actually been thinking about using peddle power myself! Awesome to see it can be done.

As you can probably tell from my name I know a fair bit about biodiesel ,back in September 2008 ,I decided to start making my own biodiesel to power my Land rover ,this was to, A,cut down on exhaust emissions B,avoid lining the prime ministers pocket C,recycle waste oil that would otherwise end up in landfill sites Since Sept 2008 ,I can honestly say that I've never been to a tax station (petrol station) ,although the initial setup was rather costly ,this money was very quickly made back in savings ,I built my own procssing plant and would be happy to share my knowledge with anyone who wants to know more ,my current land based flat is on the market,once it sells I intend to move onto a narrowboat,and guess what ,it's going to be powered by BIODIESEL.
