After building another 8 systems for those asking for help, I will continue to carry on with a smile in my little corner and keep cranking fuel through my 6 year old processor as it nears its 6,500 gallon mark.  It’s not rocket science – no wait, that would be easy compared to Nuclear Reactor Physics.  The only drawback is that the newer diesels 2006+ have injector systems that are too wimpy for this fuel to act as a ‘drop in.’

As for carbon footprints, the oil stock I use comes 5 miles away.  The oil stock we buy at the pump comes several hundred if not thousands by (probably non-bio)diesel truck.  My oil stock sequestered carbon before it was used in a restaurant’s business.  I use less than a kWh to run a 50 gallon batch.  Even with the emissions of my worst vehicle – 1997 Benz, I’m liking the sustainability of this big picture.  Energy Return on Investment (EROI) is through the roof, too.  Best of all, no tax dollars were needed for any of the research or SIMPLE equipment, just a little American initiative, and yet, still plenty of American skeptics.Go Old Navy!
