Welcome to my kick off post. I find it the height of arrogance to blog as I claim no mastery in the subjects that interest me most. I’m a greenie, a builder, a single dad, an alternative energy enthusiast, a gardener, and deeply concerned about the sustainability of the world we have created. I probably won’t write all that often but look in from time to time as I muddle my way through building a better life. For today the topic will be My charcoal powered tractor.
Years ago I launched a search for a fossil fuel free way to charge my batteries in my off grid home. The amount of useable sun in the winter on my solar array would drop to 1.5 hours from a summer high of 5. Most off grid homes resort to propane generators to make up the difference. Propane was not cheap and like any good doomer I understood how precious it was. Steam, thermo electrics, stirling engines, Hydrogen brown gas, you name it I researched and tinkered. The search for an alternative led me to Gasification, specifically charcoal gasification, as a possible locally appropriate solution. Hidden in history I discovered hundred of thousands tractors, buses and cars ran on the stuff during the second world war. Some were jury rigged but there was also also factory made kits, standardization of fuel, Fuelling stations, government pamphlets, standards of construction, government regulations and guidelines, it was all there and vanished as soon as gasoline became available again. Don’t buy it? Just another conspiracy theory? here is a great photo montage done by another woodgas nut like me. What strikes me here is just how normal this fuel was:
Imagine my surprise that a fuel that could run all my machinery with minor modification could be made at home while I heated my house…
This article is too short to go into the ins and outs of gasification, charcoal versus wood and how it works so take a look here for a primer on the subject:
If you want a glimpse into the modern masters of the technology check here:
As often happens in life priorities change. For me it was kids, a busier work schedule and correspondingly higher electrical usage which had me choose to grid connect my home to replace the generator. For a while projects around resilience took a back seat to all that make families work. It was always there though. I’ve decided to revisit these themes over the next few years as I attempt to refocus my life towards greatly increased food production, renewed energy independence, and fossil fuel replacements. Right now food comes first.
Fossil fuels have come to be critical to food production. I won’t debate the effectiveness of permaculture, lasagna garden bed making, french intensive methods, organic farming, or the joys of draft animals here. I can tell you that in times of crisis we will need millions of new large gardens seemingly overnight and one thing all those above methods are not is fast. Tractors are able to convert a manicured lawn into a plowed field in a matter of hours. With all that in mind my contribution is my 1953 Ferguson TEA20 tractor converted to run on charcoal. It was cheap and available but appropriately its from an era of simpler machines designed to run forever and be repaired by an owner in the field with minimal tools. On a sunny october afternoon it turned my weed filled 2250 sq ft garden back into the food plot it had once been. One hour of charcoal powered cultivation replaced what would have been 3 days of back breaking work for one person. Total fuel consumed 10 gallons of charcoal ,just shy of 14 Lbs., roughly equivalent to 1 US gallon of gasoline. I make my charcoal in my wood stove over the winter. This would have represented the coals from 24 hours of mid winter fires but honestly it probably took me 2 evenings of shovelling coals to accumulate this much as I’m not a fanatic or desperate. This is not a solution for a thriving society basking in economic prosperity and cheap energy. It works best if you have access to wood and are used to processing it so probably rural dwellers, who are land rich but money poor and heat with wood. It will not power an economy of commuting suburbanites but it might be enough for my northern tree covered slice of the world.
I’ve committed to plowing up 2 garden plots for friends this fall if time allows. I will be running on charcoal and will record the process. For now just some stills and some background videos will have to do. As a teaser that same 14 lbs of charcoal would have produced between 6 and 8 kW Hr of electricity for battery charging… That is another post though.
It all starts with making charcoal:

All nice and shiny running on charcoal gas at an agricultural fair. It’s never been that clean since!
