I know that terra preta's charcoal is ground to smithereens. But was it done that way by the aboriginals?

I imagine it being done as grain is powdered. Have you seen pictures of Native peoples using a long thick tree pole and slamming it up and down into a big high walled container -a little like a huge mortar and pestle?
Our government (The Land of Oz) just gave $60M to
Chevron Mobil to sequester
CO2 gas underground! I read the UK is contemplating a similar scheme
I can't understand how anyone can contemplate this technology.
How do you know if the gas will stay there?
How would you know if it left?
Will it stay for a day, a month a year, a 100 years?
Charcoal in soil
has been shown to be stable for
thousands of years and make soil more fertile and productive.
(O yes, we get rid of waste, make bio-gas and electricty into the bargain).
What is the problem with governments?
Terra preta is the way to go. It is a 'No-brainer'
