The Biochar Blues

First you take a big old drum
Then fill it full of dry cow dung
Make sure the lid's on really tight
Then just stick in a small stove pipe

Light a fire under the drum
Cook that cow dung till it's done
Open the door and there you are
What you've got is biochar

Black is the new green
Just how much could biochar do to change the world's carbon balance?
