I'm working on agri-forestry and biochar reactors on a hobby farm.

Hybrid poplars mature within a decade, and a biochar reactor is a net-energy producing reaction that produces soil improving char as a byproduct.

It won't save the world on it's own, but trees can be leveraged in powerful ways.

Can you think of anyway we could measure individuals doing this? I’m thinking reverse Bitcoin - provide a kit for people to start generating terra preta and deploying it and then give them coins for the amount of carbon they store.

Hang on. That sounds carbon-neutral at best.

Great for replacing fossil fuels, but not a carbon sequestration technique.

You can bury the char or plow it into fields as a soil ameliorant.

Or if you wanted you could literally just bury it. Then it becomes a coal plant in reverse
