Considering the dozens of books and zines about biodiesel, the hundreds of workshops held, and the thousands of pages of online discussion, it is a wonder this is the first time our collective knowledge about backyard biodiesel production has been gathered into an easy to read, how-to resource. Piedmont is a commercial operation with a homebrewer heritage. Bob and Lyle bring wisdom born of experience that few else in the industry can, written with grace and humor. This is a must read for the biodiesel nerd. It will sit on my bookshelf between my signed copy of Martin Mittelbach and my faded girlMark zine.

Small biodiesel producers have always been the most creative and enthusiastic problem solvers. This book presents the accumulated experience of two of the field's most experienced and authoritative practitioners. They not only guide you through the steps of making your own fuel, but make you excited to get started.

At last! A biofuel book that is realistic about global supply potential while being hands-on useful to the backyard or garage enthusiast. Though some first-generation biodiesel books were hampered by hype and misinformation, Estill and Armantrout get it right.
---Richard Heinberg, author, Afterburn

Lyle Estill and Bob Armantrout are some of the absolute best minds in the business when it comes to making biodiesel. Whether it's at a small scale level in your garage or a full-blown commercial biodiesel plant, these guys really know their stuff! Having a book written by these two on how to make biodiesel (and how to avoid all the mistakes along the way) is like having them right beside you. The writing is quick and easy to follow, and the chemistry explanations are great. We highly recommend it as a great book to anyone interested in making their own biodiesel, regardless of the scale.
---Graydon Blair, President, Utah Biodiesel Supply

While the economic climate may not be ripe for commercial biodiesel production, it is an essential science whose art must not be forgotten purely due to lack of profitability. Having themselves ridden the commercial roller coaster many times, the combined experience of these two authors along with their entertaining rhetoric provide a sound source for safe community-scale biodiesel production to promote clean domestic fuel production and build resilient communities.
