I was surfin' the web today and stumbled on the site listed below...

http://www.reactual.com/metaefficient/archives/biodiesel/index.html

So, grab a six pack, pull up a chair and enjoy. A good few hours can be spent reading the above site.

Just had to share, Hmmm... Making your own Biodiesel isn't really that hard.

Most of this is old info but some is interesting. The links at the bottom are worth investigating.
