There are many roads to sustainability, and the biofuels road is definitely one.

I actually purchased an 85′ SD300 Benz a number of years ago (2004?) and built a bio-diesel processor…the whole 9 yards. Was fun finally having a sunroof, too! I was living at an eco-village outside of my town of Eugene (www.lostvalley.org — great permaculture programs, and much more), so it was a blast giving people rides into and back from town in my Golden Bio-Benz.

The down side of it was that I was living way outside of Eugene — by about 18 miles…the commute was nice, but, ironically, not very sustainable.

I took the plunge, moved into town with the family, sold the car, gave the biodiesel processor to the community at the eco-village…and started riding my bike. Suddenly, an 8-15 minute commute–by pedal power no less! And I bought a new laptop with the proceeds.
Going straight veggie, obviously, makes more sense than doing biodiesel. My twin brother is still aiming to buy a Benz and do the same thing you’re doing. Anyone can change the bulbs in their house from incandescent to CF. Your step is a little more gutsier.
May you inspire others with it…
