Amtrak’s B20 biodiesel train

The Amtrak Heartland Flyer has been fueled entirely with B20 (20% biodiesel and 80% regular diesel) since April, pulling big loads between Oklahoma City and Fort Worth. Not only has it shown that biodiesel works just fine in stenuous real-life situations, it has also been honored as an innovator by Time in their 50 Best Innovations of 2010.

The biodiesel is made from rendered cattle fat and amazingly not only burns cleaner than regular diesel, it’s also cleaner than plant biodiesel.
