Nice build Neal!

Could you describe it for us? What is the big tank on the left? What does the control box looking thing do? Is the smaller tank to the right the Riche’ style retort? Are you running the generator off of it?

I have questions for anyone who might know, about the nature of the gas produced. I know it’s richer than gasses from partial combustion gasifiers. Is it rich enough that engine power isn’t sacrificed? The gas also has a higher hydrogen content. How will this effect engine operation? Would it require adjusting the timing?
