Learn how you can make FREE generator fuel at home, using wood branches and a unique device called a “wood gasifier.”

60 second video explains

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 turns 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 gasifiers provided fuel when oil and gas weren’t available.

– “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. ”

– “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.”
