Well BillyS. for open source proven for large engines I do not think you will beat just using/basing off of the Mother Earth News Gasifier system.
The design has certainly been out their for decades. Nothing secret about it.
It has fuel powered V-8’s, I-6’s and I believe even down to large four cylinder generators.
Two DOW members I know use it successfully.
Ron Lemler and Paul Halverson. Read here:
Your open source change the world concept . . . . even the best of designs takes hundreds and hundreds of hours under year around varying conditions to really get one of these system reliably producing. We know. Here on the DOW we hand hold fellows through this.
Guys who have walked this path know no matter what design tweaks recommended it just will nor work for the majority of the diverse folks out there.
One woodgasifier system at a time. One operator using that at a time is the only proven pathway.
You want operator easier?
Go with a pre-made charcoal system. And still a learning curve. With varying operational condition continually throwing you curve balls.
And you: the offering up designer; will be faulted for most users inabilities. Their overoptimism’s using wet wood. Shoreline/drift wood. BBQ charcoal briquets. Sap laden Green full in leaf arborists free chop. Painted build debris wood. MDF scrap’s and tear outs.
Sigh. You go ahead with your open-source concept. It is your life. To spend-expend as you wish.
