Reader Reviews



– “Very detailed, loving it.”

– “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. ”

– “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.”

– “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.”
