Few weeks ago I went to Austria to see a bio-diesel factory. Awesome technology. 1 liter of any kind of vegetable or animal fat, 100ml of methanol and a bit of caustic soda and you obtain 1 liter of bio-diesel 100ml of glycerin and a bit of fertilyzer. No waste of anything and everything is bio-degradable and organic.
A german company is building the first hi-performance turbo diesel motorcycle engine with a configuration similar to a Triumph in-line twin.

it's so easy to make bio-diesel at home, Internet is plenty of resources that describes what you need and how-to do.
But what makes me astonished is the Joe Cell.
Search joe cell using google video or youtube.
Here a good resource:

And the Proton Cell is a joe cell version for air-cooled engines.
