Hi All,
A lot of First’s today.
First day of school for the young’uns. School bus just picked them up.
First day of Fall/Autumn.
Our first hard killing frost.
The black walnut will be dropping it’s nuts and leaf sprigs big-time.
Garden re-sets now.
I love the Fall

First day I wore my heavy gloves and face cover on the dual sport ride in the work! We didn’t get a frost but it was a little chilly. Archery deer season opened this morning marking the start of my favorite season!
My first day of spring we have high winds blowing and sunshine over the field helping to dry it out so i can drag some limbs over with the tractor on our 30 deg slopes 2nd day of the spring and more winds and warm & sunny again sure gives you a lift after a cold wet winter that’s for sure .

I’m so glad it’s still over 90 here today…I think…
Not sure if this would apply to small scale gasification.
As you actively work in the gasification and/or pyrolysis sector I wanted to make sure that you were aware of the proposed rulemaking by EPA regarding such units. Please see the EPA email below and the links offered. We all need to make sure the enviros don’t get their way in lumping gasification and pyrolysis into the Federal solid waste incinerator rules. That is the last place we need to be associated with.
Today, the EPA issued an advanced notice of proposed rulemaking (ANPRM) to assist in the potential development of regulations for pyrolysis and gasification units. These units are used to convert solid or semi-solid feedstocks, including solid waste (e.g., municipal solid waste, commercial and industrial waste, hospital/medical/infectious waste, sewage sludge, other solid waste), biomass, plastics, tires, and organic contaminants in soils and oily sludges to useful products such as energy, fuels and chemical commodities. Pyrolysis and gasification are often described as heat-induced thermal decomposition processes.
Through recent interactions with stakeholders, EPA has learned that pyrolysis and gasification processes are more widely being used to convert waste into useful products or energy. An ANPRM will provide an opportunity for a large and diverse group of stakeholders, including potentially impacted facilities, small businesses, and state, local, and tribal governments, to participate in the data and information gathering process and provide information on the details of pyrolysis and gasification units and processes. Based on data and information received through this ANPRM, the agency will evaluate how best to regulate the pyrolysis and gasification units.
A pre-publication version of the ANPRM and a fact sheet are available on the web at: Advance Notice of Proposed Rulemaking on Pyrolysis and Gasification Units | US EPA

Always best to not be blowing around what you are doing.
Well since my local hunting forum has some 1170 pages of replys on the bigfoot/sasquatch thread, I think it will move pretty quick! Subject gets brought up every few days with story’s of all kinds
My dream trucks are out there. It was exciting to look this one over. Sad to not to be able to nurse this one back on the road. In my shape, it just would not happen. Not to mention all the started projects that need to be finished. The only thing missing is a tilt front. Had that on a Jeep, can’t beat it with a stick.
Looks an awefull lot like this project sitting out back of the shop. 12v Cummins, juice brakes so no cdl needed, 5 yard box on it 7 speed conversion with a heavy clutch. Waiting on the drive line shop and then find a pto and pump to get it on the road for my buddy’s construction company
I’m high on the hog with all the free pallets I’ve been getting from work this week. Rained hard and heavy all week so I don’t feel nervous about a burn either. Time to make more charcoal this weekend! Got my table saw fixed too so I can hack up the boards easier for a TLUD run.
Those fiberglass tip down hoods where common on the IH trucks we has some of them on the farm as a kid. They are nice until someone backs the other truck into the front corner missing the fender but taking out the blinker and breaking the fiberglass where it mounts. Not an easy fix of the farm budget.

I never knew how easy it was to build girder forks until I really started looking into it. I’m still whipping up the shapes but it’s slowly coming together for a future build. Might get some of the frame done tomorrow and follow up with images. I was thinking of either a leaf spring fork but I’m starting to think that a full scratch made Girder might be more fitting for this screaming hot honda clone engine I’ve got.
No woodgas yet, but it is coming…some day. I know you guys like videos.
Spend some time on an CHP, build from scraps, calculations are right. Motor is a Yanmar clone 8 hp, delivering around 3 kW electric power. If it is direct drive maybe 4 kW. All aircooled, but very stinky. Now idea what to do about that. Exhaust is going to be cooled and maybe filtered over an charcoalfilter before going out. Someone any experience with charcoal filter, with it stay open, engine grade pieces to be used?
If I find myself a 3000 rpm motor , it can be converted to direct drive, along with a flywheel. The single cylinder isnot turning so smooth. Can’t find the sweetspot around 3000 rpm where e-power is zero. I reckon that is the single cylinder.
Parts are waiting for a motor.
And some automation. The governor is doing a good job, kept rpm’s stable for a few minutes.
combined heat and power , boiler had 115 gallons antifreeze at 84 f used less the gallon of propane in half hour and raised temperature of boiler to 92 f . Was also outputting power to grid at 8 kw .
temp of exhaust at engine 426 f temp of exhaust at boiler 267 f . 7,636 btu 2 Kw .
8 kW power to grid should give 16 kW heat? And 8 kW lost in space? Anyway, that is the way I am calculating.
Hello Joep, I am familiar with these Chinese engines, otherwise they work nicely but have worse combustion, I don’t know if you will eliminate this with a filter, and the addition of wood gas will improve the condition of the exhaust gases.
Otherwise, the exhaust of the diesel engine does not contain more than 20-30% of energy, more is discharged through the cooling system.
Joep and Tone there is still an active U.S. based forum dedicated to micro-CHP do-it-yourself systems:
https://www.microcogen.info
Search it up yourself just by microcogen.info
The maths been done and achieved by many there. Many directions tried, and promoted, over the course of 15-20 years.
Some of the take-aways for those efforts:
Direct drive locks you into ONE matched specialized engine and gen head combo.
Belt drive properly engineered will only lose you 1-2% and give you the flexibility to wide use change and source both side of it independently.
Water cooled will be quieter inherently and be much easier for farm out the engine heats.
Multiple cylinder engines at V-Twin (NOT two cylinder vertical) and inline 3-cylinders will be much quieter and smoother. And have then NO electrical output flicker with the single cylinder four stoke power event versus 50 and 60 hertz 2 and 4 pole generator heads.
I quit participating there as they drifted off into Tiny homes and Green-Spinning soap boxing as the new must-do’s.
The info’s though are still there just needing to be cherry picked out.
Enjoy info diving.
