Need Power? Got Wood?

Turn tree branches into FREE GENERATOR FUEL with a “Wood Gasifier”

Study Schematics

Survive well when others won’t

Provide reliable power to your family and neighbors in dark times and crisis using just the sticks and branches God placed at your feet.

A wood gasifier is a small scale refinery that gives you the ability to turn wood from your own property into free motor fuel in minutes. The fuel is called “wood gas” and you can use it to make off grid electric power, run farm equipment, heating, hot water and more. It only takes 5-10 minutes to make gas. Gas is produced on demand so it needs no storage.

During WWII 1,000,000 wood & charcoal gasifiers provided fuel when oil and gas weren’t available.

Reader Reviews


4.9 stars


– “I am a red seal fabricator welder and I found this book informative and technically sound. However the format makes things understandable in such a way that even a non-trades person could make the final product happen.

– “I would like to thank you so much for the plans. My generator started immediately the very first time!”

“Easy to understand and a terrific amount of illustrations.”

– “I have built a couple small experimental gasifiers and have the first edition of this book. The author put even more details in the 2nd edition and hides nothing and has taken the mystery out of how they work and how to build one. Anyone with the ability to cut and weld can build one.”

– “Very detailed, loving it.”

– “I am a member of a ARES/RACES team that, if called upon, would help provide emergency radio communications to our county in the event of a disaster… I looked into multiple ways of keeping the lights on and the radio station up and decided a wood gasifier was my best and most economical option. Of all the gasifiers I studied, Petersen’s is the best documented, best supported and in my estimation, the best quality one for the do-it-yourselfer.”

– “As builder and avid user of Ben’s gasifier design I highly recommend his latest book. I have all of Ben’s books. Such great material. Ben’s latest book ties it all together. For the builders the info is very valuable saving hours trying to dial in a gasifier. For the historian, potential builders, and gasifier enthusiast it’s a must for the collection. I’m not much of a welder or fabricator I found the building directions very easy to follow.”

– “This is a great project with a very valuable unit in the end. I’ll admit it was a little more work than I thought at the beginning but we ended up with an amazing gas generator.

– “Perfect for the home fabricator.”

– “If you want to understand how a Gasifyer works, buy this book.
If you want to understand how to build a Gasifyer, buy this book.
If you need a technical guide, with all pictures and dimensions, buy this book.
If at the end of your project if you want a working Gasifyer, buy this book.”

– “This book is truly a step by step gasifier build that is extremely efficient. The calculation (very easy to understand) is also shown to size the gasifier to the motor one plans to use. All parts are easily obtained through Home Depot and other sources. Part numbers are also given to make finding them a breeze. This book is badass!!”
