Make Your Own Biodiesel

With the August Bank Holiday Weekend arriving in the UK, maybe this is the opportunity you've been waiting for to create some Biodiesel. But where can you find quality instructions for how to make Biodiesel, I hear you ask. Well, in Make, of course. And it is an American, Kip Kay, who gives the fine presentation, and another American, Rob Elam, who wrote the original article, Biodiesel was invented in Belgium:

Where it did come from?
"On August 31, 1937, G. Chavanne of the University of Brussels (Belgium) was granted a patent for a 'Procedure for the transformation of vegetable oils for their uses as fuels' (fr. 'Procédé de Transformation d’Huiles Végétales en Vue de Leur Utilisation comme Carburants') Belgian Patent 422,877. This patent described the alcoholysis (often referred to as transesterification) of vegetable oils using ethanol (and mentions methanol) in order to separate the fatty acids from the glycerol by replacing the glycerol with short linear alcohols. This appears to be the first account of the production of what is known as 'biodiesel' today."
