[Terrapreta] Char made made under pressurized conditions?

[David Yarrow]

i am encouraged by the imagery of hot steam forcing water vapors deep into 
the dense networks of micropores in charcoal.  a steam treatment should 
rapidly reduce char's initial resistance to absorbing water.  might even 
induce a few explosions and ruptures to the cellular celluose matrix of 
micropores -- ripping open larger channels for macroscopic lifeforms to join 
the community.

and since i'm most certainly making my char for soil enhancement, i 
definitely intend to quench my first 2008 batch of hot char with sea water. 
not just water, but sea water, to inject a full spectrum mineral solution 
into the char, and thus improve its potential as microbial habitat.  the 
sooner microbes find water and a full menu of minerals, the sooner they will 
take up residence in the char.

for a green & peaceful planet,
