This is the beating heart of a farm design based on the concept of #Silvopasture. My thinking is this is how Bitcoin will directly integrate into agriculture beyond farmers and ranchers accepting payment in Bitcoin for their products.

To be brief this system converts woody farm waste to energy, #biochar, and wood vinegar. A Silvopasture, properly managed, can produce a massive amount of wood for feedstock. The Electricity produced is used to power Bitcoin miners and a wood chipper. The residual heat of the miners and generator is used to reduce the moisture content of the woody feedstock and then heat a greenhouse. The biochar and wood vinegar are used as soil amendments and much more.

Biochar added to soil acts as a battery for water (making trees, shrubs, and grasses drought tolerant) and nutrients. NOTE: This is a much longer discussion but suffice it to say that I want as much Biochar in my soil as I can get. It makes soil resilient.

Wood Vinegar? Yeah, that's a massive discussion all by itself but . . . you want it in the soil as well.

Electricity produced: Possibly 2 MW but . . . it depends.

Bitcoin mined: It depends but maybe 0.11 BTC per day.

Biochar/Wood Vinegar produced: That depends on the gasifier.

I've given up with trying to capture the sin gasses & create the bio-char with an air tight kiln.

I'm now using an open air kiln with high sides 1200mm using corrugated iron & then quenching with water. The corrugated iron restricts the oxygen & reflects the heat. Only the top layer gets oxygen & you add wood as the top layer converts to charcoal. I have no shortage of feedstock right now because I'm thinning my trees.

The quality of the biochar is not as high (incomplete pyrolysis) but it produces multiple times more volume of charcoal for the same effort/time.

I'd love to capture the gas but haven't seen an economical way.

Yeah, to capture the gas there is a substantial amount of capital that has to be spent and that's not just something everyone can do. For small holders, homesteaders and residential doing what you're doing is the best way to go because you still get char and that's gold.
