The stainless steel stock pot idea is interesting. Martin Payne, (35 mi. N. of me) brought a shiny new one over and his two teenage boys used it to construct an Anderson TLUD cookstove. He also brought grassfed beef steakburgers which we cooked on the stove when it was finished. Even though I already had ten stoves, I bought a stockpot and made a copy, using a stainless steel bain marie for the burn pot. Lately, when I screen/sort my charcoal, I pick out my “half baked” charcoal for use in the stoves, and since they are TLUD, I end up with finished charcoal. Meanwhile, I’ve been burning out grates like mad, so I now have some hunks of rebar ready to weld into a sturdier grate. The charcoal burns hotter/longer and can destroy grates. My Tom Reed Woodgas Campstove XL took about two years to burn out (about a third of the way up from the bottom), even though it was thin stainless, so I use an old chimney pipe liner inside my stainless bain marie to protect the stainless with an expendable part. This might work for you also. I have also severely distorted the pot lid, so now I just “clamp it down” harder. Regarding the bicycle, have you seen the two person motocross sidehack bikes? (There are pedal versions, and powered versions.) My current idea is to build a utility sidecar for a Honda CB250 wreck I found at the junkyard (destroyed front end), and place the gasifier on the sidecar. My usual grocery run is 25 miles round trip, just about perfect for a small charcoal unit. I could “top it off” before heading home. So, I have the sidecar wheel, the frame layout, and a donor front end (with alternate plan for some Earles Leading Link forks). The cooler could be part of the utility sidecar frame. I’m planning on using a cyclone and the Gilmore Filter (grease barrel size), but need a smaller reactor. (Recycled Propane tank?) Lately I’ve been “obsessed” with making/sorting/sifting charcoal and have done 72 fifty-five gallon sessions.
Have you considered an electric bike with the charger/generator on a small bicycle trailer? I’ll be looking for your pics. Thanks.
